                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, January 1, 2018), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not accidentally dropped due to a printing or computer error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

Sec. 202.21  Purpose and scope.

    (a) This subpart sets forth the procedures to be followed when a 
subpoena, order, or other demand (hereinafter referred to as a 
``demand'') of a court or other authority is issued for the production 
or disclosure of (1) any material contained in the files of the 
Department of Energy (DOE), (2) any information relating to material 
contained in the files of the DOE, or (3) any information or material 
acquired by any person while such person was an employee of the DOE as a 
part of the performance of his official duties or because of his 
official status.
    (b) For purposes of this subpart, the term ``Employee of the DOE'' 
includes all officers and employees of the United States appointed by, 
or subject to the supervision, jurisdiction, or control of, the 
Administrator of DOE.



Sec. 202.22  Production or disclosure prohibited unless approved by 
appropriate DOE official.

    No employee or former employee of the DOE shall, in response to a 
demand of a court or other authority, produce any material contained in 
the file of the DOE or disclose any information relating to material 
contained in the files of the DOE, or disclose any information or 
produce any material acquired as part of the performance of his official 
duties or because of his official status without prior approval of the 
General Counsel of DOE.



Sec. 202.23  Procedure in the event of a demand for production or
disclosure.

    (a) Whenever a demand is made upon an employee or former employee of 
the DOE for the production of material or the disclosure of information 
described in Sec. 202.21(a), he shall immediately notify the Regional 
Counsel for the region where the issuing authority is located. The 
Regional Counsel shall immediately request instructions from the General 
Counsel of DOE.
    (b) If oral testimony is sought by the demand, an affidavit, or, if 
that is not feasible, a statement by the party seeking the testimony or 
his attorney, setting forth a summary of the testimony desired, must be 
furnished for submission by the Regional Counsel to the General Counsel.



Sec. 202.24  Final action by the appropriate DOE official.

    If the General Counsel approves a demand for the production of 
material or disclosure of information, he shall so notify the Regional 
Counsel and such other persons as circumstances may warrant.

[[Page 6]]



Sec. 202.25  Procedure where a decision concerning a demand is not
made prior to the time a response to the demand is required.

    If response to the demand is required before the instructions from 
the General Counsel are received, a U.S. attorney or DOE attorney 
designated for the purpose shall appear with the employee or former 
employee of the DOE upon whom the demand has been made, and shall 
furnish the court or other authority with a copy of the regulations 
contained in this subpart and inform the court or other authority that 
the demand has been, or is being, as the case may be, referred for the 
prompt consideration of the appropriate DOE official and shall 
respectfully request the court or authority to stay the demand pending 
receipt of the requested instructions.



Sec. 202.26  Procedure in the event of an adverse ruling.

    If the court or other authority declines to stay the effect of the 
demand in response to a request made in accordance with Sec. 202.25 
pending receipt of instructions, of if the court or other authority 
rules that the demand must be complied with irrespective of instructions 
not to produce the material or disclose the information sought, the 
employee or former employee upon whom the demand has been made shall 
respectfully decline to comply with the demand. ``United States ex rel

to run is not to be included. The last day of the period so computed is

notice of the document prior to the return date of the document.
    (d)(1) A witness subpoenaed by the DOE shall be paid the same fees

    (2) If in the course of a proceeding conducted pursuant to subpart M 
or O, a subpoena is issued at the request of a person other than an 
officer or agency of the United States, the witness fees and mileage

document or information because of a claim of attorney-client or other 
privilege, the person submitting the certification required by paragraph

Sec. 205.9  General filing requirements.

    (a) Purpose and scope. The provisions of this section shall apply to 
all documents required or permitted to be filed with the DOE or with a 
State Office.
    (b) Signing. All applications, petitions, requests, appeals, 
comments or any other documents that are required to be signed, shall be 
signed by the person filing the document or a duly authorized 
representative. Any application, appeal, petition, request, complaint or 
other document filed by a duly authorized representative shall contain a 
statement by such person certifying that he is a duly authorized 
representative, unless an DOE form other wise requires. (A false 
certification is unlawful under the provisions of 18 U.S.C. 1001 
(1970)).
    (c) Labeling. An application, petition, or other request for action 
by the DOE or a State Office should be clearly labeled according to the 
nature of the action involved (e.g., ``Application for Assignment'') 
both on the document and on the outside of the envelope in which the 
document is transmitted.
    (d) Obligation to supply information. A person who files an 
application, petition, complaint, appeal or other request for action is 
under a continuing obligation during the proceeding to provide the DOE 
or a State Office with any new or newly discovered information that is 
relevant to that proceeding. Such information includes, but is not 
limited to, information regarding any other application, petition, 
complaint, appeal or request for action that is subsequently filed by 
that person with any DOE office or State Office.
    (e) The same or related matters. A person who files an application, 
petition, complaint, appeal or other request for action by the DOE or a 
State Office shall state whether, to the best knowledge of that person, 
the same or related issue, act or transaction has been or presently is 
being considered or investigated by any DOE office, other Federal 
agency, department or instrumentality; or by a State Office, a state or 
municipal agency or court; or by any law enforcement agency; including, 
but not limited to, a consideration or investigation in connection with 
any proceeding described in this part. In addition, the person shall 
state whether contact has been made by the person or one acting on his 
behalf with any person who is employed by the DOE or any State Office 
with regard to the same issue, act or transaction or a related issue, 
act or transaction arising out of the same factual situation; the name 
of the person contacted; whether the contact was verbal or in writing; 
the nature and substance of the contact; and the date or dates of the 
contact.
    (f) Request for confidential treatment. (1) If any person filing a 
document with the DOE or a State Office claims that some or all the 
information contained in the document is exempt from the mandatory 
public disclosure requirements of the Freedom of Information Act (5 
U.S.C. 552 (1970)), is information referred to in 18 U.S.C. 1905 (1970), 
or is otherwise exempt by law from public disclosure, and if such person 
requests the DOE or a State Office not to disclose such information, 
such person shall file together with the document a second copy of the 
document from which has been deleted the information for which such 
person wishes to claim confidential treatment. The person shall indicate 
in the original document that it is confidential or contains 
confidential information and may file a statement specifying the 
justification for non-disclosure of the information for which 
confidential treatment is claimed. If the person states that the

[[Page 14]]

information comes within the exception in 5 U.S.C. 552(b)(4) for trade 
secrets and commercial or financial information, such person shall 
include a statement specifying why such information is privileged or 
confidential. If the person filing a document does not submit a second 
copy of the document with the confidential information deleted, the DOE 
or a State Office may assume that there is no objection to public 
disclosure of the document in its entirety.
    (2) The DOE or a State Office retains the right to make its own 
determination with regard to any claim of confidentiality. Notice of the 
decision by the DOE or a State Office to deny such claim, in whole or in 
part, and an opportunity to respond shall be given to a person claiming 
confidentiality of information no less than five days prior to its 
public disclosure.
    (g) Separate applications, petitions or requests. Each application, 
petition or request for DOE action shall be submitted as a separate 
document, even if the applications, petitions, or requests deal with the 
same or a related issue, act or transaction, or are submitted in 
connection with the same proceeding.



Sec. 205.10  Effective date of orders.

    Any order issued by the DOE or a State Office under this chapter is 
effective as against all persons having actual notice thereof upon 
issuance, in accordance with its terms, unless and until it is stayed, 
modified, suspended, or rescinded. An order is deemed to be issued on 
the date, as specified in the order, on which it is signed by an 
authorized representative of the DOE or a State Office, unless the order 
provides otherwise.



Sec. 205.11  Order of precedence.

    (a) If there is any conflict or inconsistency between the provisions 
of this part and any other provision of this chapter, the provisions of 
this part shall control with respect to procedure.
    (b) Notwithstanding paragraph (a) of this section, subpart I of part 
212 of this chapter shall control with respect to prenotification and

Sec. 205.80  Purpose and scope.

    (a) This subpart establishes the procedures for the filing of a 
formal request for an interpretation and for the consideration of such 
request. Responses, which may include verbal or written responses to 
general inquiries or to other than formal written requests for 
interpretation filed with the General Counsel or his delegate or a 
Regional Counsel, are not interpretations and merely provide general 
information.
    (b) A request for interpretation that includes, or could be 
construed to include an application for an exception or an exemption may 
be treated solely as a request for interpretation and processed as such.

Sec. 205.81  What to file.

    (a) A person filing under this subpart shall file a ``Request for 
Interpretation,'' which should be clearly labeled as such both on the 
request and on the outside of the envelope in which the request is 
transmitted, and shall be in writing and signed by the person filing the 
request. The person filing the request shall comply with the general 
filing requirements stated in Sec. 205.9 in addition to the 
requirements stated in this subpart.
    (b) If the person filing the request wishes to claim confidential 
treatment for any information contained in the request or other 
documents submitted under this subpart, the procedures set out in Sec. 
205.9(f) shall apply.



Sec. 205.82  Where to file.

    A request for interpretation shall be filed with the General Counsel 
or his delegate or with the appropriate Regional Counsel at the address 
provided in Sec. 205.12.

FR 17803, Apr. 26, 1978]



Sec. 205.83  Contents.

    (a) The request shall contain a full and complete statement of all 
relevant facts pertaining to the circumstances, act or transaction that 
is the subject of the request and to the DOE action

[[Page 18]]

sought. Such facts shall include the names and addresses of all affected 
persons (if reasonably ascertainable) and a full discussion of the 
pertinent provisions and relevant facts contained in the documents 
submitted with the request. Copies of all relevant contracts, 
agreements, leases, instruments, and other documents shall be submitted 
with the request. When the request pertains to only one step of a larger 
integrated transaction, the facts, circumstances, and other relevant 
information pertaining to the entire transaction must be submitted.
    (b) The request for interpretation shall include a discussion of all 
relevant authorities, including, but not limited to, DOE rulings, 
regulations, interpretations and decisions on appeals and exceptions 
relied upon to support the particular interpretation sought therein.



Sec. 205.84  DOE evaluation.

    (a) Processing. (1) The DOE may initiate an investigation of any 
statement in a request and utilize in its evaluation any relevant facts 
obtained by such investigation. The DOE may accept submissions from 
third persons relevant to any request for interpretation provided that 
the person making the request is afforded an opportunity to respond to 
all third person submissions. In evaluating a request for 
interpretation, the DOE may consider any other source of information. 
The DOE on its own initiative may convene a conference, if, in its 
discretion, it considers that such conference will advance its 
evaluation of the request.
    (2) The DOE shall issue its interpretation on the basis of the 
information provided in the request, unless that information is 
supplemented by other information brought to the attention of the 
General Counsel or a Regional Counsel during the proceeding. The 
interpretation shall, therefore, depend for its authority on the 
accuracy of the factual statement and may be relied upon only to the 
extent that the facts of the actual situation correspond to those upon 
which the interpretation was based.
    (3) If the DOE determines that there is insufficient information 
upon which to base a decision and if upon request additional information 
is not submitted by the person requesting the interpretation, the DOE 
may refuse to issue an interpretation.
    (b) Criteria. (1) The DOE shall base an interpretation on the FEA 
and EPAA and the regulations and published rulings of the DOE as applied 
to the specific factual situation.
    (2) The DOE shall take into consideration previously issued 
interpretations dealing with the same or a related issue.



Sec. 205.85  Decision and effect.

    (a) An interpretation may be issued after consideration of the 
request for interpretation and other relevant information received or 
obtained during the proceeding.
    (b) The interpretation shall contain a statement of the information 
upon which it is based and a legal analysis of and conclusions regarding 
the application of rulings, regulations and other precedent to the 
situation presented in the request.
    (c) Only those persons to whom an interpretation is specifically 
addressed and other persons upon whom the DOE serves the interpretation 
and who are directly involved in the same transaction or act may rely 
upon it. No person entitled to rely upon an interpretation shall be 
subject to civil or criminal penalties stated in subpart P of this part 
for any act taken in reliance upon the interpretation, notwithstanding 
that the interpretation shall thereafter be declared by judicial or 
other competent authority to be invalid.
    (d) An interpretation may be rescinded or modified at any time. 
Rescission or modification may be effected by notifying persons entitled 
to rely on the interpretation that it is rescinded or modified. This 
notification shall include a statement of the reasons for the recision 
or modification and, in the case of a modification, a restatement of the 
interpretation as modified.
    (e) An interpretation is modified by a subsequent amendment to the 
regulations or ruling to the extent that it is inconsistent with the 
amended regulation or ruling.

[[Page 19]]

    (f)(1) Any person aggrieved by an interpretation may submit a 
petition for reconsideration to the General Counsel within 30 days of 
service of the interpretation from which the reconsideration is sought. 
There has not been an exhaustion of administrative remedies until a 
period of 30 days from the date of service of the interpretation has 
elapsed without receipt by the General Counsel of a petition for 
reconsideration or, if a petition for reconsideration of the 
interpretation has been filed in a timely manner, until that petition 
has been acted on by the General Counsel. However, a petition to which 
the General Counsel does not respond within 60 days of the date of 
receipt thereof, or within such extended time as the General Counsel may 
prescribe by written notice to the petitioner concerned within that 60 
day period, shall be considered denied.
    (2) A petition for reconsideration may be summarily denied if--
    (i) It is not filed in a timely manner, unless good cause is shown; 
or
    (ii) It is defective on its face for failure to state, and to 
present facts and legal argument in support thereof, that the 
interpretation was erroneous in fact or in law, or that it was arbitrary 
or capricious.

the petitioner does not establish that--
    (i) The petition was filed by a person aggrieved by an 
interpretation;
    (ii) The interpretation was erroneous in fact or in law; or
    (iii) The interpretation was arbitrary or capricious. The denial of 
a petition shall be a final order of which the petitioner may seek 
judicial review.

Subpart L [Reserved]



          Subpart M_Conferences, Hearings, and Public Hearings



Sec. 205.170  Purpose and scope.

    This subpart establishes the procedures for requesting and 
conducting a DOE conference, hearing, or public hearing. Such 
proceedings shall be convened in the discretion of the DOE, consistent 
with the requirements of the FEAA.



Sec. 205.171  Conferences.

    (a) The DOE in its discretion may direct that a conference be 
convened, on its own initiative or upon request by a person, when it 
appears that such conference will materially advance the proceeding. The 
determination as to who may attend a conference convened under this 
subpart shall be in the discretion of the DOE, but a conference will 
usually not be open to the public.
    (b) A conference may be requested in connection with any proceeding 
of the DOE by any person who might be aggrieved by that proceeding. The 
request may be made in writing or verbally, but must include a specific 
showing as to why such conference will materially advance the 
proceeding. The request shall be addressed to the DOE office that is 
conducting the proceeding.
    (c) A conference may only be convened after actual notice of the 
time, place, and nature of the conference is provided to the person who 
requested the conference.
    (d) When a conference is convened in accordance with this section, 
each person may present views as to the issue or issues involved. 
Documentary evidence may be presented at the conference, but will be 
treated as if submitted in the regular course of the proceedings. A 
transcript of the conference will not usually be prepared. However, the 
DOE in its discretion may have a verbatim transcript prepared.
    (e) Because a conference is solely for the exchange of views 
incident to a proceeding, there will be no formal reports or findings 
unless the DOE in its discretion determines that such would be 
advisable.



Sec. 205.172  Hearings.

    (a) The DOE in its discretion may direct that a hearing be convened 
on its own initiative or upon request by a person, when it appears that 
such hearing will materially advance the proceedings. The determination 
as to who may attend a hearing convened under this subpart shall be in 
the discretion of DOE, but a hearing will usually not be open to the 
public. Where the hearing involves a matter arising under part 213, the 
Director of Oil Imports shall be notified as to its time and place, in 
order that he or his representative may present views as to the issue or 
issues involved.
    (b) A hearing may only be requested in connection with an 
application for an exception or an appeal. Such request may be by the 
applicant, appellant, or any other person who might be aggrieved by the 
DOE action sought. The request shall be in writing and shall include a 
specific showing as to why such hearing will materially advance the 
proceeding. The request shall be addressed to the DOE office that is 
considering the application for an exception or the appeal.
    (c) The DOE will designate an agency official to conduct the 
hearing, and will specify the time and place for the hearing.
    (d) A hearing may only be convened after actual notice of the time, 
place, and nature of the hearing is provided both to the applicant or 
appellant and to any other person readily identifiable by the DOE as one 
who will be aggrieved by the DOE action involved. The notice shall 
include, as appropriate:

[[Page 21]]

    (1) A statement that such person may participate in the hearing; or
    (2) A statement that such person may request a separate conference 
or hearing regarding the application or appeal.
    (e) When a hearing is convened in accordance with this section, each 
person may present views as to the issue or issues involved. Documentary 
evidence may be presented at the hearing, but will be treated as if 
submitted in the regular course of the proceedings. A transcript of the 
hearing will not usually be prepared. However, the DOE in its discretion 
may have a verbatim transcript prepared.
    (f) The official conducting the hearing may administer oaths and 
affirmations, rule on the presentation of information, receive relevant 
information, dispose of procedural requests, determine the format of the 
hearing, and otherwise regulate the course of the hearing.
    (g) Because a hearing is solely for the exchange of views incident 
to a proceeding, there will be no formal reports or findings unless the 
DOE in its discretion determines that such would be advisable.

Sec. 205.173  Public hearings.

    (a) A public hearing shall be convened incident to a rulemaking:
    (1) When the proposed rule or regulation is likely to have a 
substantial impact on the Nation's economy or large numbers of 
individuals or businesses; or
    (2) When the DOE determines that a public hearing would materially 
advance the consideration of the issue. A public hearing may be 
requested by any interested person in connection with a rulemaking 
proceeding, but shall only be convened on the initiative of the DOE 
unless otherwise required by statute.
    (b) A public hearing may be convened incident to any proceeding when 
the DOE in its discretion determines that such public hearing would 
materially advance the consideration of the issue.
    (c) A public hearing may only be convened after publication of a 
notice in the Federal Register, which shall include a statement of the 
time, place, and nature of the public hearing.
    (d) Interested persons may file a request to participate in the 
public hearing in accordance with the instructions in the notice 
published in the Federal Register. The request shall be in writing and 
signed by the person making the request. It shall include a description 
of the person's interest in the issue or issues involved and of the 
anticipated content of the presentation. It shall also contain a 
statement explaining why the person would be an appropriate spokesperson 
for the particular view expressed.
    (e) The DOE shall appoint a presiding officer to conduct the public 
hearing. An agenda shall be prepared that shall provide, to the extent 
practicable, for the presentation of all relevant views by competent 
spokespersons.
    (f) A verbatim transcript shall be made of the hearing. The 
transcript, together with any written comments submitted in the course 
of the proceeding, shall be made available for public inspection and 
copying in the public docket room, as provided in Sec. 205.15.
    (g) The information presented at the public hearing, together with 
the written comments submitted and other relevant information developed 
during the course of the proceeding, shall provide the basis for the DOE 
decision.

Sec. 205.190  Purpose and scope.

    (a) This subpart establishes the procedures for determining the 
nature and extent of violations of the DOE regulations in parts 210, 
211, and 212 and the procedures for issuance of a Notice of Probable 
Violation, a Proposed Remedial Order, a Remedial Order, an Interim 
Remedial Order for Immediate Compliance, a Remedial Order for Immediate 
Compliance, a Notice of Probable Disallowance, a Proposed Order of 
Disallowance, an Order of Disallowance, or a Consent Order. Nothing in 
these regulations shall affect the authority of DOE enforcement 
officials in coordination with the Department of Justice to initiate 
appropriate civil or criminal enforcement actions in court at any time.
    (b) When any report required by the ERA or any audit or 
investigation discloses, or the ERA otherwise discovers, that there is 
reason to believe a violation of any provision of this chapter, or any 
order issued thereunder, has occurred, is continuing or is about to 
occur, the ERA may conduct an inquiry to determine the nature and extent 
of the violation. A Remedial Order or Order of Disallowance may be 
issued thereafter by the Office of Hearings and Appeals. The ERA may 
commence enforcement proceedings by serving a Notice of Probable 
Violation, a Notice of Probable Disallowance, a Proposed Remedial Order, 
a Proposed Order of Disallowance, or an Interim Remedial Order for 
Immediate Compliance.



Sec. 205.191  [Reserved]



Sec. 205.192  Proposed remedial order.

    (a) If the ERA finds, after the 30-day or other period authorized 
for reply to the Notice of Probable Violation, that a violation has 
occurred, is continuing, or is about to occur, it may issue a Proposed 
Remedial Order, which shall set forth the relevant facts and law.
    (b) The ERA may issue a Proposed Remedial Order at any time it finds 
that a violation has occurred, is continuing, or is about to occur even 
if it has not previously issued a Notice of Probable Violation.
    (c) The ERA shall serve a copy of the Proposed Remedial Order upon 
the person to whom it is directed. The ERA shall promptly publish a 
notice in the Federal Register which states the person to whom the 
Proposed Remedial Order is directed, his address, and the products, 
dollar amounts, time period, and geographical area specified in the 
Proposed Remedial Order. The notice shall indicate that a copy of the 
Proposed Remedial Order with confidential information, if any, deleted 
may be obtained from the ERA and that within 15 days after the date of 
publication any aggrieved person may file a Notice of Objection with the 
Office of Hearings and Appeals of accordance with Sec. 205.193. The ERA 
shall mail copies of the Federal Register notice to all readily 
identifiable persons who are likely to be aggrieved by issuance of the 
Proposed Remedial Order as a final order.
    (d) The Proposed Remedial Order shall set forth the proposed 
findings of fact and conclusions of law upon which it is based. It shall 
also include a discussion of the relevant authorities which support the 
position asserted, including rules, regulations, rulings, 
interpretations and previous decisions issued by DOE or its predecessor 
agencies. The Proposed Remedial Order shall be accompanied by a 
declaration executed by the DOE employee primarily knowledgeable about 
the facts of the case stating that, to the best of declarant's knowledge 
and belief, the findings of fact are correct.
    (e) The ERA may amend or withdraw a Proposed Remedial Order at its 
discretion prior to the date of service of a Statement of Objections in 
that proceeding. The date of service of the amended documents shall be 
considered the date of service of the Proposed Remedial Order in 
calculating the time periods specified in this part 205.



Sec. 205.192A  Burden of proof.

    (a) In a Proposed Remedial Order proceeding the ERA has the burden 
of establishing a prima facie case as to the validity of the findings of 
fact and conclusions of law asserted therein. The ERA shall be deemed to 
meet this burden by the service of a Proposed Remedial Order that meets 
the requirements of Sec. 205.192(d) and any supplemental information 
that may be made available under Sec. 205.193A.

[[Page 23]]

    (b) Once a prima facie case has been established, a person who 
objects to a finding of fact or conclusion of law in the Proposed 
Remedial Order has the burden of going forward with the evidence. 
Furthermore, the proponent of additional factual representations has the 
burden of going forward with the evidence.
    (c) Unless otherwise specified by the Director of the Office of 
Hearings and Appeals or his designee, the proponent of an order or a 
motion or additional factual representations has the ultimate burden of 
persuasion.



Sec. 205.193  Notice of Objection.

    (a) Within 15 days after publication of the notice of a Proposed 
Remedial Order in the Federal Register any aggrieved person may file a 
Notice of Objection to the Proposed Remedial Order with the Office of 
Hearings and Appeals. The Notice shall be filed in duplicate, shall 
briefly describe how the person would be aggrieved by issuance of the 
Proposed Remedial Order as a final order and shall state the person's 
intention to file a Statement of Objections. No confidential information 
shall be included in a Notice of Objection. The DOE shall place one copy 
of the Notice in the Office of Hearings and Appeals Public Docket Room.
    (b) A person who fails to file a timely Notice of Objection shall be 
deemed to have admitted the findings of fact and conclusions of law as 
stated in the Proposed Remedial Order. If a Notice of Objection is not 
filed as provided by paragraph (a) of this section, the Proposed 
Remedial Order may be issued as a final order.
    (c) A person who files a Notice of Objection shall on the same day 
serve a copy of the Notice upon the person to whom the Proposed Remedial 
Order is directed, the DOE Office that issued the Proposed Remedial 
Order, and the DOE Assistant General Counsel for Administrative 
Litigation.
    (d) The Notice shall include a certification of compliance with the 
provisions of this section, the names and addresses of each person 
served with a copy of the Notice, and the date and manner of service.
    (e) If no person files a timely Notice of Objection, ERA may request 
the Office of Hearings and Appeals to issue the Proposed Remedial Order 
as a final Remedial Order.
    (f) In order to exhaust administrative remedies with respect to a 
Remedial Order proceeding, a person must file a timely Notice of 
Objection and Statement of Objections with the Office of Hearings and 
Appeals.



Sec. 205.193A  Submission of ERA supplemental information.

    Within 20 days after service of a Notice of Objection to a Proposed 
Remedial Order the ERA may serve, upon the person to whom the Proposed 
Remedial Order was directed, supplemental information relating to the 
calculations and determinations which support the findings of fact set 
forth in the Proposed Remedial Order.



Sec. 205.194  Participants; official service list.

    (a) Upon receipt of a Notice of Objection, the Office of Hearings 
and Appeals shall publish a notice in the Federal Register which states 
the person to whom the Proposed Remedial Order is directed, his address 
and the products, dollar amounts, time period, and geographical area 
specified in the Proposed Remedial Order. The notice shall state that 
any person who wishes to participate in the proceeding must file an 
appropriate request with the Office of Hearings and Appeals.
    (b) The Office that issued the Proposed Remedial Order and the 
person to whom the Order is directed shall be considered participants 
before the Office of Hearings and Appeals at all stages of an 
enforcement proceeding. Any other person whose interest may be affected 
by the proceeding may file a request to participate in the proceeding 
with the Office of Hearings and Appeals within 20 days after publication 
of the notice referred to in paragraph (a) of this section. The request 
shall contain
    (1) The person's name, address, and telephone number and similar 
information concerning his duly authorized representative, if any;
    (2) A detailed description of the person's interest in the 
proceeding;

[[Page 24]]

    (3) The specific reasons why the person's active involvement in the 
proceeding will substantially contribute to a complete resolution of the 
issues to be considered in the proceeding;
    (4) A statement of the position which the person intends to adopt in 
the proceeding; and
    (5) A statement of the particular aspects of the proceeding, e.g. 
oral argument, submission of briefs, or discovery, in which the person 
wishes to actively participate.
    (c) After considering the requests submitted pursuant to paragraph 
(b) of this section, the Office of Hearings and Appeals shall determine 
those persons who may participate on an active basis in the proceeding 
and the nature of their participation. Participants with similar 
interests may be required to consolidate their submissions and to appear 
in the proceeding through a common representative.
    (d) Within 30 days after publication of the notice referred to in 
paragraph (a) of this section, the Office of Hearings and Appeals shall 
prepare an official service list for the proceeding. Within the same 30 
day period the Office of Hearings and Appeals shall mail the official 
service list to all persons who filed requests to participate. For good 
cause shown a person may be placed on the official service list as a 
non-participant, for the receipt of documents only. An opportunity shall 
be afforded to participants to oppose the placement of a non-participant 
on the official service list.
    (e) A person requesting to participate after the period for 
submitting requests has expired must show good cause for failure to file 
a request within the prescribed time period.
    (f) The Office of Hearings and Appeals may limit the nature of a 
person's participation in the proceeding, if it finds that the facts 
upon which the person's request was based have changed or were incorrect 
when stated or that the person has not been actively participating or 
has engaged in disruptive or dilatory conduct. The action referred to in 
this provision shall be taken only after notice and an opportunity to be 
heard are afforded.



Sec. 205.195  Filing and service of all submissions.

    (a)(1) Statements of Objections, Responses to such Statements, and 
any motions or other documents filed in connection with a proceeding 
shall meet the requirements of Sec. 205.9 and shall be filed with the 
Office of Hearings and Appeals in accordance with Sec. 205.4. Unless 
otherwise specified, any participant may file a response to a motion 
within five days of service.
    (2) All documents shall be filed in duplicate, unless they contain 
confidential information, in which case they must be filed in 
triplicate.
    (3) If a person claims that any portion of a document which he is 
filing contains confidential information, such information should be 
deleted from two of the three copies which are filed. One copy from 
which confidential information has been deleted will be placed in the 
Office of Hearings and Appeals Public Docket Room.
    (b)(1) Persons other than DOE offices shall on the date a submission 
is filed serve each person on the official service list. Service shall 
be made in accordance with Sec. 205.7 and may also be made by deposit 
in the regular United States mail, properly stamped and addressed, when 
accompanied by proof of service consisting of a certificate of counsel 
or an affidavit of the person making the service. If any filing arguably 
contains confidential information, a person may serve copies with the 
confidential information deleted upon all persons on the official 
service list except DOE offices, which shall be served both an original 
filing and one with deletions.
    (2) A DOE office shall on the date it files a submission serve all 
persons on the official service list, unless the filing arguably 
contains confidential information. In that case the DOE office shall 
notify the person to whom the information relates of the opportunity to 
identify and delete the confidential information. The DOE Office may 
delay the service of a submission containing arguably confidential 
information upon all persons other than the possessor of the 
confidential information and other DOE offices up to 14 days. The 
possessor of the confidential information shall serve the filing with 
any

[[Page 25]]

deletions upon all persons on the official service list within such time 
period.
    (c) Any filing made under this section shall include a certification 
of compliance by the filer with the provisions of this subpart. The 
person serving a document shall file a certificate of service, which 
includes the date and manner of service for each person on the official 
service list.



Sec. 205.196  Statement of objections.

    (a) A person who has filed a Notice of Objection shall file a 
Statement of Objections to a Proposed Remedial Order within 40 days 
after service of the Notice of Objection. A request for an extension of 
time for filing must be submitted in writing and may be granted for good 
cause shown.
    (b) The Statement of Objections shall set forth the bases for the 
objections to the issuance of the Proposed Remedial Order as a final 
order, including a specification of the issues of fact or law which the 
person intends to contest in any further proceeding involving the 
compliance matter which is the subject of the Proposed Remedial Order. 
The Statement shall set forth the findings of fact contained in the 
Proposed Remedial Order which are alleged to be erroneous, the factual 
basis for such allegations, and any alternative findings which are 
sought. The Statement shall include a discussion of all relevant 
authorities which support the position asserted. The Statement may 
include additional factual representations which are not referred to in 
the Proposed Remedial Order and which the person contends are material 
and relevant to the compliance proceeding. For each additional factual 
representation which the person asserts should be made, the Statement 
shall include reasons why the factual representation is relevant and 
material, and the manner in which its validity is or will be 
established. The person shall also specify the manner in which each 
additional issue of fact was raised in any prior administrative 
proceeding which led to issuance of the Proposed Remedial Order, or the 
reasons why it was not raised.
    (c) A Statement of Objections that is filed by the person to whom a 
Proposed Remedial Order is directed shall include a copy of any relevant 
Notice of Probable Violation, each Response thereto, the Proposed 
Remedial Order, and any relevant work papers or supplemental information 
previously provided by ERA. Copies of this material must also be

participant may file a Response. If any motions are served with the 
Statement of Objections, a participant shall have 30 days from the date 
of service to respond to such submissions, notwithstanding any shorter 
time periods otherwise required in this subpart. The Response shall 
contain a full discussion of the position asserted and a discussion of 
the legal and factual bases which support that position. The Response 
may also contain a request that any issue of fact or law advanced in a 
Statement of Objections be dismissed. Any such request shall be 
accompanied by a full discussion of the reasons supporting the 
dismissal.
    (b) A participant may submit a Reply to any Response within 10 days 
after the date of service of the Response.



Sec. 205.198  Discovery.

    (a) If a person intends to file a Motion for Discovery, he must file 
it at the same time that he files his Statement of Objections or at the 
same time he files his Response to a Statement of Objections, whichever 
is earlier. All Motions for Discovery and related filings must be served 
upon the person to whom the discovery is directed. If the person to whom 
the discovery is directed is not on the official service list, the

written material in his possession;
    (2) A person respond to written interrogatories;
    (3) A person admit to the genuineness of any relevant document or 
the truth of any relevant fact; or
    (4) The deposition of a material witness be taken.
    (c) A Motion for Discovery shall set forth the reasons why the 
particular discovery is necessary in order to obtain relevant and 
material evidence and shall explain why such discovery would not unduly 
delay the proceeding.
    (d) Within 20 days after a Motion for Discovery is served, a 
participant or a person to whom the discovery is directed may file a 
request that the Motion be denied in whole or in part, stating the 
reasons which support the request.
    (e) Discovery may be conducted only pursuant to an Order issued by 
the Office of Hearings and Appeals. A Motion for Discovery will be 
granted if it is concluded that discovery is necessary for the party to 
obtain relevant and material evidence and that discovery will not unduly 
delay the proceeding. Depositions will be permitted if a convincing 
showing is made that the participant cannot obtain the material sought 
through one of the other discovery means specified in paragraph (b) of 
this section.
    (f) The Director of the Office of Hearings and Appeals or his 
designee may issue subpoenas in accordance with Sec. 205.8 in support 
of Discovery Orders, except that Sec. 205.8 (h)(2), (3), and (4) shall 
not apply to such subpoenas.
    (g) The Office of Hearings and Appeals may order that any direct 
expenses incurred by a person to produce evidence pursuant to a Motion 
for Discovery be charged to the person who filed the Motion.
    (h)(1) If a person fails to comply with an order relating to 
discovery, the Office of Hearings and Appeals may order appropriate 
sanctions.
    (2) It shall be the duty of aggrieved participants to request that

or appeal only upon issuance of the determination referred to in Sec. 
205.199B.



Sec. 205.198A  Protective order.

    A participant who has unsuccessfully attempted in writing to obtain 
information that another participant claims is confidential may file a 
Motion for Discovery and Protective Order. This motion shall meet the 
requirements of Sec. 205.198 and shall specify the particular 
confidential information that the movant seeks and the reasons why the 
information is necessary to adequately present the movant's position in 
the proceeding. A copy of the written request for information, a 
certification concerning when and to whom it was served and a copy of 
the response, if any, shall be appended to the motion. The motion must 
give the possessor of the information notice that a Response to the 
Motion must be filed within ten days. The Response shall specify the 
safeguards, if any, that should be imposed if the information is ordered 
to be released. The Office of Hearings and Appeals may issue a 
Protective Order upon consideration of the Motion and the Response.



Sec. 205.199  Evidentiary hearing.

    (a) Filing Requirements. At the time a person files a Statement of 
Objections he may also file a motion requesting an evidentiary hearing 
be convened. A motion requesting an evidentiary hearing may be filed by 
any other participant within 30 days after that participant is served 
with a Statement of Objections.
    (b) Contents of Motion for Evidentiary Hearing. A Motion for 
Evidentiary Hearing shall specify each disputed issue of fact and the 
bases for the alternative findings the movant asserts. The movant shall 
also describe the manner in which each disputed issue of fact was raised 
in any prior administrative proceeding which led to issuance of the 
Proposed Remedial Order, or why it was not raised. The movant shall with 
respect to each disputed or alternative finding of fact:

[[Page 27]]

    (1) As specifically as possible, identify the witnesses whose 
testimony is required;
    (2) State the reasons why the testimony of the witnesses is 
necessary; and
    (3) State the reasons why the asserted position can be effectively 
established only through the direct questioning of witnesses at an 
evidentiary hearing.
    (c) Response to Motion for Evidentiary Hearing. Within 20 days after 
service of any Motion for Evidentiary Hearing, the Office that issued 
the Proposed Remedial Order shall, and any other participant may file a 
Response with the Office of Hearings and Appeals. The Response shall 
specify:
    (1) Each particular factual representation which is accepted as 
correct for purposes of the proceeding;
    (2) Each particular factual representation which is denied;
    (3) Each particular factual representation which the participant is 
not in a position to accept or deny;
    (4) Each particular factual representation which is not accepted and 
the participant wishes proven by the submission of evidence;
    (5) Each particular factual representation which the participant is 
prepared to dispute through the testimony of witnesses or the submission 
of verified documents; and
    (6) Each particular factual representation which the participant 
asserts should be dismissed as immaterial or irrelevant.
    (d) Prehearing Conferences. After all submissions with respect to a 
Motion for Evidentiary Hearing are filed, the Office of Hearings and 
Appeals may conduct conferences or hearings to resolve differences of 
view among the participants.
    (e) Decision on Motion for Evidentiary Hearing. After considering 
all relevant information received in connection with the Motion, the 
Office of Hearings and Appeals shall enter an Order. In the Order the 
Office of Hearings and Appeals shall direct that an evidentiary hearing 
be convened if it concludes that a genuine dispute exists as to relevant 
and material issues of fact and an evidentiary hearing would 
substantially assist it in making findings of fact in an effective 
manner. If the Motion for Evidentiary Hearing is granted in whole or in 
part, the Order shall specify the parties to the hearing, any 
limitations on the participation of a party, and the issues of fact set 
forth for the evidentiary hearing. The Order may also require parties 
that have adopted similar positions to consolidate their presentations 
and to appear at the evidentiary hearing through a common 
representative. If the Motion is denied, the Order may allow the movant 
to file affidavits and other documents in support of his asserted 
findings of fact.
    (f) Review of Decision. The Order of the Office of Hearings and 
Appeals with respect to a Motion for Evidentiary Hearing shall be 
subject to further administrative review or appeal only upon issuance of 
the determination referred to in Sec. 205.199B.
    (g) Conduct of Evidentiary Hearing. All evidentiary hearings 
convened pursuant to this section shall be conducted by the Director of 
the Office of Hearings and Appeals or his designee. At any evidentiary 
hearing the parties shall have the opportunity to present material 
evidence which directly relates to a particular issue of fact set forth 
for hearing. The presiding officer shall afford the parties an 
opportunity to cross examine all witnesses. The presiding officer may 
administer oaths and affirmations, rule on objections to the 
presentation of evidence, receive relevant material, rule on any motion 
to conform the Proposed Remedial Order to the evidence presented, rule 
on motions for continuance, dispose of procedural requests, determine 
the format of the hearing, modify any order granting a Motion for 
Evidentiary Hearing, direct that written motions or briefs be provided 
with respect to issues raised during the course of the hearing, issue 
subpoenas, and otherwise regulate the conduct of the hearing. The 
presiding officer may take reasonable measures to exclude duplicative 
material from the hearing, and may place appropriate limitations on the 
number of witnesses that may be called by a party. The presiding officer 
may also require that evidence be submitted through affidavits or other 
documents if the direct testimony of witnesses will unduly delay the 
orderly

[[Page 28]]

progress of the hearing and would not contribute to resolving the issues 
involved in the hearing. The provisions of Sec. 205.8 which relate to 
subpoenas and witness fees shall apply to any evidentiary hearing, 
except that subsection Sec. 205.8(h) (2), (3), and (4) shall not apply.



Sec. 205.199A  Hearing for the purpose of oral argument only.

    (a) A participant is entitled upon timely request to a hearing to 
present oral argument with respect to the Proposed Remedial Order, 
whether or not an evidentiary hearing is requested or convened. A 
participant's request shall normally be considered untimely, if made 
more than 10 days after service of a determination regarding any motion 
filed by the requestor or, if no motions were filed by him, if made 
after the date for filing his Reply or his Response to a Statement of 
Objections.
    (b) If an evidentiary hearing is convened, and a hearing for oral 
argument is requested, the Office of Hearings and Appeals shall 
determine whether the hearing for oral argument shall be held in 
conjunction with the evidentiary hearing or at a separate time.
    (c) A hearing for the purpose of receiving oral argument will 
generally be conducted only after the issues involved in the proceeding 
have been delineated, and any written material which the Office of 
Hearings and Appeals has requested to supplement a Statement of 
Objections or Responses has been submitted. The presiding officer may 
require further written submissions in support of any position advanced 
or issued at the hearing, and shall allow responses any such 
submissions.



Sec. 205.199B  Remedial order.

    (a) After considering all information received during the 
proceeding, the Director of the Office of Hearings and Appeals or his 
designee may issue a final Remedial Order. The Remedial Order may adopt 
the findings and conclusions contained in the Proposed Remedial Order or 
may modify or rescind any such finding or conclusion to conform the 
Order to the evidence or on the basis of a determination that the 
finding or conclusion is erroneous in fact or law or is arbitrary or 
capricious. In the alternative, the Office of Hearings and Appeals may 
determine that no Remedial Order should be issued or may remand all or a 
portion of the Proposed Remedial Order to the issuing DOE office for 
further consideration or modification. Every determination made pursuant 
to this section shall state the relevant facts and legal bases 
supporting the determination.
    (b) The DOE shall serve a copy of any determination issued pursuant 
to paragraph (a) of this section upon the person to whom it is directed, 
any person who was served with a copy of the Proposed Remedial Order, 
the DOE office that issued the Proposed Remedial Order, the DOE 
Assistant General Counsel for Administrative Litigation and any other 
person on the official service list. Appropriate deletions may be made 
in the determinations to ensure that confidentiality of information 
protected from disclosure under 18 U.S.C. 1905 and 5 U.S.C. 552. A copy 
of the determination with appropriate deletions to protect confidential 
and proprietary data shall be placed in the Office of Hearings and 
Appeals Public Docket Room.



Sec. 205.199C  Appeals of remedial order to FERC.

    (a) The person to whom a Remedial Order is issued by the Office of 
Hearings and Appeals may file an administrative appeal if the Remedial 
Order proceeding was initiated by a Notice of Probable Violation issued 
after October 1, 1977, or, in those situations in which no Notice of 
Probable Violation was issued, if the proceeding was initiated by a 
Proposed Remedial Order issued after October 1, 1977.
    (b) Any such appeal must be initiated within 30 days after service 
of the Order by giving written notice to the Office of Hearings and 
Appeals that the person to whom a Remedial Order is issued wishes to 
contest the Order.
    (c) The Office of Hearings and Appeals shall promptly advise the 
Federal Energy Regulatory Commission of its receipt of a notice 
described in paragraph (b) of this section.
    (d) The Office of Hearings and Appeals may, on a case by case basis, 
set reasonable time limits for the Federal

[[Page 29]]

Energy Regulatory Commission to complete its action on such an appeal 
proceeding.
    (e) In order to exhaust administrative remedies, a person who is 
entitled to appeal a Remedial Order issued by the Office of Hearings and 
Appeals must file a timely appeal and await a decision on the merits. 
Any Remedial Order that is not appealed within the 30-day period shall 
become effective as a final Order of the DOE and is not subject to 
review by any court.



Sec. Sec. 205.199D-205.199E  [Reserved]



Sec. 205.199F  Ex parte communications.

    (a) No person who is not employed or otherwise supervised by the 
Office of Hearings and Appeals shall submit ex parte communications to 
the Director or any person employed or otherwise supervised by the 
Office with respect to any matter involved in Remedial Order or Order of 
Disallowance proceedings.
    (1) Ex parte communications include any ex parte oral or written 
communications relative to the merits of a Proposed Remedial Order, 
Interim Remedial Order for Immediate Compliance, or Proposed Order of 
Disallowance proceeding pending before the Office of Hearings and 
Appeals. The term shall not, however, include requests for status 
reports, inquiries as to procedures, or the submission of proprietary or 
confidential information. Notice that proprietary or confidential 
submissions have been made shall be given to all persons on the official 
service list.
    (b) If any communication occurs that violates the provisions of this 
section, the Office of Hearings and Appeals shall promptly make the 
substance of the communication available to the public and serve a copy 
of a written communication or a memorandum summarizing an oral 
communication to all participants in the affected proceeding. The Office 
of Hearings and Appeals may also take any other appropriate action to 
mitigate the adverse impact to any person whose interest may be affected 
by the ex parte contact.



Sec. 205.199G  Extension of time; Interim and Ancillary Orders.

    The Director of the Office of Hearings and Appeals or his designee 
may permit upon motion any document or submission referred to in this 
subpart other than appeals to FERC to be amended or withdrawn after it 
has been filed or to be filed within a time period different from that 
specified in this subpart. The Director or his designee may upon motion 
or on his own initiative issue any interim or ancillary Orders, 
reconsider any determinations, or make any rulings or determinations 
that are deemed necessary to ensure that the proceedings specified in 
this subpart are conducted in an appropriate manner and are not unduly 
delayed.



Sec. 205.199H  Actions not subject to administrative appeal.

    A Notice of Probable Violation, Notice of Proposed Disallowance, 
Proposed Remedial Order or Interim Remedial Order for Immediate 
Compliance issued pursuant to this subpart shall not be an action from 
which there may be an administrative appeal pursuant to subpart H. In 
addition, a determination by the Office of Hearings and Appeals that a 
Remedial Order, an Order of Disallowance, or a Remedial Order for 
Immediate Compliance should not be issued shall not be appealable 
pursuant to subpart H.



Sec. 205.199I  Remedies.

    (a) A Remedial Order, a Remedial Order for Immediate Compliance, an 
Order of Disallowance, or a Consent Order may require the person to whom 
it is directed to roll back prices, to make refunds equal to the amount 
(plus interest) charged in excess of those amounts permitted under DOE 
Regulations, to make appropriate compensation to third persons for 
administrative expenses of effectuating appropriate remedies, and to 
take such other action as the DOE determines is necessary to eliminate 
or to compensate for the effects of a violation or any cost disallowance 
pursuant to Sec. 212.83 or Sec. 212.84. Such action may include a 
direction to the person to whom the Order is issued to establish an 
escrow account or take other measures to

[[Page 30]]

make refunds directly to purchasers of the products involved, 
notwithstanding the fact that those purchasers obtained such products 
from an intermediate distributor of such person's products, and may 
require as part of the remedy that the person to whom the Order is 
issued maintain his prices at certain designated levels, notwithstanding 
the presence or absence of other regulatory controls on such person's 
prices. In cases where purchasers cannot be reasonably identified or 
paid or where the amount of each purchaser's overcharge is incapable of 
reasonable determination, the DOE may refund the amounts received in 
such cases directly to the Treasury of the United States on behalf of 
such purchasers.
    (b) The DOE may, when appropriate, issue final Orders ancillary to a 
Remedial Order, Remedial Order for Immediate Compliance, Order of 
Disallowance, or Consent Order requiring that a direct or indirect 
recipient of a refund pass through, by such means as the DOE deems 
appropriate, including those described in paragraph (a) of this section, 
all or a portion of the refund, on a pro rata basis, to those customers 
of the recipient who were adversely affected by the initial overcharge. 
Ancillary Orders may be appealed to the Office of Hearings and Appeals 
only pursuant to subpart H.



Sec. 205.199J  Consent order.

    (a) Notwithstanding any other provision of this subpart, the DOE may 
at any time resolve an outstanding compliance investigation or 
proceeding, or a proceeding involving the disallowance of costs pursuant 
to Sec. 205.199E with a Consent Order. A Consent Order must be signed 
by the person to whom it is issued, or a duly authorized representative, 
and must indicate agreement to the terms contained therein. A Consent 
Order need not constitute an admission by any person that DOE 
regulations have been violated, nor need it constitute a finding by the 
DOE that such person has violated DOE regulations. A Consent Order 
shall, however, set forth the relevant facts which form the basis for 
the Order.
    (b) A Consent Order is a final Order of the DOE having the same 
force and effect as a Remedial Order issued pursuant to Sec. 205.199B 
or an Order of Disallowance issued pursuant to Sec. 205.199E, and may 
require one or more of the remedies authorized by Sec. 205.199I and 
Sec. 212.84(d)(3). A Consent Order becomes effective no sooner than 30 
days after publication under paragraph (c) of this section, unless (1) 
the DOE makes a Consent Order effective immediately, because it 
expressly deems it necessary in the public interest, or (2) the Consent 
Order involves a sum of less than $500,000 in the aggregate, excluding 
penalties and interest, in which case it will be effective when signed 
both by the person to whom it is issued and the DOE, and will not be 
subject to the provisions of paragraph (c) of this section unless the 
DOE determines otherwise. A Consent Order shall not be appealable 
pursuant to the provisions of Sec. 205.199C or Sec. 205.199D and 
subpart H, and shall contain an express waiver of such appeal or 
judicial review rights as might otherwise attach to a final Order of the 
DOE.
    (c) When a Consent Order has been signed, both by the person to whom 
it is issued and the DOE, the DOE will publish notice of such Consent 
Order in the Federal Register and in a press release to be issued 
simultaneously therewith. The Federal Register notice and the press 
release will state at a minimum the name of the company concerned, a 
brief summary of the Consent Order and other facts or allegations 
relevant thereto, the address and telephone number of the DOE office at 
which copies of the Consent Order will be available free of charge, the 
address to which comments on the Consent Order will be received by the 
DOE, and the date by which such comments should be submitted, which date 
will not be less than 30 days after publication of the Federal Register 
notice. After the expiration of the comment period the DOE may withdraw 
its agreement to the Consent Order, attempt to negotiate a modification 
of the Consent Order, or issue the Consent Order as signed. The DOE will 
publish in the Federal Register, and by press release, notice of any 
action taken on a Consent Order and such explanation of

[[Page 31]]

the action taken as deemed appropriate. The provisions of this paragraph 
shall be applicable notwithstanding the fact that a Consent Order may 
have been made immediately effective pursuant to paragraph (b) of this 
section (except in cases where the Consent Order involves sums of less 
than $500,000 in the aggregate, excluding penalties and interest).
    (d) At any time and in accordance with the procedures of subpart J, 
a Consent Order may be modified or rescinded, upon petition by the 
person to whom the Consent Order was issued, and may be rescinded by the 
DOE upon discovery of new evidence which is materially inconsistent with 
evidence upon which the DOE's acceptance of the Consent Order was based. 
Modifications of a Consent Order which is subject to public comment 
under the provisions of paragraph (c) of this section, which in the 
opinion of the DOE significantly change the terms or the impact of the 
original Order, shall be republished under the provisions of that 
paragraph.
    (e) Notwithstanding the issuance of a Consent Order, the DOE may 
seek civil or criminal penalties or compromise civil penalties pursuant 
to subpart P concerning matters encompassed by the Consent Order, unless 
the Consent Order by its terms expressly precludes the DOE from so 
doing.
    (f) If at any time after a Consent Order becomes effective it 
appears to the DOE that the terms of the Consent Order have been 
violated, the DOE may refer such violations to the Department of Justice 
for appropriate action in accordance with subpart P.

Sec. 205.280  Purpose and scope.

    This subpart establishes special procedures pursuant to which 
refunds may be made to injured persons in order to remedy the effects of 
a violation of the regulations of the Department of Energy. This subpart 
shall be applicable to those situations in which the Department of 
Energy is unable to readily identify persons who are entitled to

[[Page 33]]

refunds specified in a Remedial Order, a Remedial Order for Immediate 
Compliance, an Order of Disallowance or a Consent Order, or to readily 
ascertain the amounts that such persons are entitled to receive.



Sec. 205.281  Petition for implementation of special refund procedures.

    (a) At any time after the issuance of a Remedial Order (including 
for purposes of this subpart a Remedial Order for Immediate Compliance 
and an Order of Disallowance), or a Consent Order, the Special Counsel 
of the Department of Energy, the ERA Office of Enforcement, or any other 
enforcement official of the Department of Energy may file with the 
Office of Hearings and Appeals a Petition for the Implementation of 
Special Refund Procedures.
    (b) The Petition shall state that the person filing it has been 
unable readily either to identify the persons who are entitled to 
refunds to be remitted pursuant to a Remedial Order or a Consent Order 
or to ascertain the amounts of refunds that such persons are entitled to 
receive. The Petition shall request that the Office of Hearings and 
Appeals institute appropriate proceedings under this subpart to 
distribute the funds referred to in the enforcement documents.
    (c) The Petition shall contain a copy of each relevant enforcement 
document, shall be filed in duplicate, and shall meet the requirements 
of Sec. 205.9 of this part.



Sec. 205.282  Evaluation of petition by the Office of Hearings
and Appeals.

    (a) After considering the Petition, the Director of the Office of 
Hearings and Appeals or his designee shall issue a Proposed Decision and 
Order. The Proposed Decision and Order shall generally describe the 
nature of the particular refund proceeding and shall set forth the 
standards and procedures that the Office of Hearings and Appeals intends 
to apply in evaluating refund claims.
    (b) The Proposed Decision and Order shall be published in the 
Federal Register together with a statement that any member of the public 
may submit written comments to the Office of Hearings and Appeals with 
respect to the matter. At least 30 days following publication in the 
Federal Register shall be provided for the submission of comments.
    (c) After considering the comments submitted, the Director of the 
Office of Hearings and Appeals or his designee shall issue a final 
Decision and Order which shall govern the disposition of the refunds. 
The final Decision and Order shall also be published in the Federal 
Register.
    (d) The final Decision and Order shall set forth the standards and 
procedures that will be used in evaluating individual Applications for 
Refunds and distributing the refund amount. Those standards and 
procedures shall be consistent with the provisions of this subpart.
    (e) In establishing standards and procedures for implementing refund 
distributions, the Office of Hearings and Appeals shall take into 
account the desirability of distributing the refunds in an efficient, 
effective and equitable manner and resolving to the maximum extent 
practicable all outstanding claims. In order to do so, the standards for 
evaluation of individual claims may be based upon appropriate 
presumptions.



Sec. 205.283  Applications for refund.

    (a) Any person entitled to a refund pursuant to a final Decision and 
Order issued pursuant to Sec. 205.282 may file an Application for 
Refund. All Applications must be signed by the applicant and specify the 
DOE order to which they pertain. Any Application for a refund in excess 
of $100 must be file in duplicate, and a copy of that Application will 
be available for public inspection in the DOE Public Docket Room at 2000 
M Street, NW., Washington, DC. Any applicant who believes that his 
Application contains confidential information must so indicate on the 
first page of his Application and submit two additional copies of his 
Application from which the information that the applicant claims is 
confidential has been deleted, together with a statement specifying why 
any such information is privileged or confidential.
    (b) The contents of an Application for Refund shall be specified in 
the final

[[Page 34]]

Decision and Order referred to in Sec. 205.282(c). A filing deadline 
for Applications shall also be specified in the final Decision and 
Order, and shall be no less than 90 days after the publication of the 
Order in the Federal Register.
    (c) Each Application shall be in writing and signed by the 
applicant, and shall indicate whether the applicant or any person acting 
on his instructions has filed or intends to file any other Application 
or claim of whatever nature regarding the matters at issue in the 
underlying enforcement proceeding. Each Application shall also include a 
sworn statement by the applicant that all information in his Application 
is true and correct to the best of his knowledge and belief.



Sec. 205.284  Processing of applications.

    (a) The Director of the Office of Hearings and Appeals may appoint 
an administrator to evaluate Applications under guidelines established 
by the Office of Hearings and Appeals. The administrator, if he is not a 
Federal Government employee, may be compensated from the funds referred 
to in the Remedial Order or Consent Order. The administrator may design 
and distribute an optional application form for the convenience of the 
applicants.
    (b) The Office of Hearings and Appeals or its designee may initiate 
an investigation of any statement made in an Application and may require 
verification of any document submitted in support of a claim. In 
evaluating an Application, the Office of Hearings and Appeals or its 
designee may solicit and consider information obtained from any source 
and may on its own initiative convene a hearing or conference, if it 
determines that a hearing or conference will advance its evaluation of 
an Application.
    (c) The Director of the Office of Hearings and Appeals or his 
designee shall conduct any hearing or conference convened with respect 
to an Application for Refund and shall specify the time and place for 
the hearing or conference and notify the applicant. The official 
conducting the hearing may administer oaths and affirmations, rule on 
the presentation of information, receive relevant information, dispose 
of procedural requests, determine the format of the hearing and 
otherwise regulate the course of the hearing. The provisions of Sec. 
205.8 of this part which relate to subpoenas and witness fees shall 
apply to any hearing convened with respect to an application for refund, 
except that Sec. 205.8(h) (2), (3) and (4) shall not apply.
    (d) Upon consideration of an Application and other relevant 
information received during the course of a refund proceeding, the 
Director of the Office of Hearings and Appeals or his designee shall 
issue an order granting or denying the Application. The order shall 
contain a concise statement of the relevant facts and the legal basis 
for the order. A copy of the order, with such modification as is 
necessary to ensure the confidentiality of information protected from 
public disclosure by 18 U.S.C. 1905, may be obtained upon request by an 
applicant or any other person who participated in the proceeding.



Sec. 205.285  Effect of failure to file a timely application.

    An Application for Refund must be filed no later than the date that 
the Office of Hearings and Appeals establishes pursuant to Sec. 
205.283(b). Any Application that is not filed on a timely basis may be 
summarily dismissed. The Office of Hearings and Appeals or its designee 
may, however, grant extensions of time for good cause shown. Any request 
for an extension of time must generally be submitted in writing prior to 
the deadline.



Sec. 205.286  Limitations on amount of refunds.

    (a) The aggregate amount of all refunds approved by the Office of 
Hearings and Appeals or its designee in a given case shall not exceed 
the amount to be remitted pursuant to the relevant DOE enforcement 
order, plus any accumulated interest, reduced by the amount of any 
administrative costs approved by the Office of Hearings and Appeals. In 
the event that the aggregate amount of approved claims exceeds the 
aggregate amount of funds specified above, the Office of Hearings and 
Appeals may make refunds on a pro rata basis. The Office of Hearings and 
Appeals may delay payment of any

[[Page 35]]

refunds until all Applications have been processed.
    (b) The Office of Hearings and Appeals may decline to consider 
Applications for refund amounts that, in view of the direct 
administrative costs involved, are too small to warrant individual 
consideration.



Sec. 205.287  Escrow accounts, segregated funds and other guarantees.

    (a) In implementing the refund procedures specified in this subpart, 
the Director of the Office of Hearings and Appeals or his designee shall 
issue an order providing for the custody of the funds to be tendered 
pursuant to the Remedial Order or Consent Order. This Order may require 
placement of the funds in an appropriate interest-bearing escrow 
account, retention of the funds by the firm in a segregated account 
under such terms and conditions as are specified by the DOE, or the 
posting of a sufficient bond or other guarantee to ensure payment.
    (b) All costs and charges approved by the Office of Hearings and 
Appeals and incurred in connection with the processing of Applications 
for Refund or incurred by an escrow agent shall be paid from the amount 
of funds, including any accumulated interest, to be remitted pursuant to 
the Remedial Order or Consent Order.
    (c) After the expenses referred to in paragraph (b) of this section 
have been satisfied and refunds distributed to successful applicants, 
any remaining funds remitted pursuant to the Remedial Order or Consent 
Order shall be deposited in the United States Treasury or distributed in 
any other manner specified in the Decision and Order referred to in 
Sec. 205.282(c).
    (d) Funds contained in an escrow account, segregated fund, or 
guaranteed by other approved means shall be disbursed only upon written 
order of the Office of Hearings and Appeals.



Sec. 205.288  Interim and ancillary orders.

    The Director of the Office of Hearings and Appeals or his designee 
may issue any interim or ancillary orders, or make any rulings or 
determinations to ensure that refund proceedings, including the actions 
of the administrator and the custodian of the funds involved in a refund 
proceeding, are conducted in an appropriate manner and are not unduly 
delayed.

Sec. 205.328  Environmental requirements for Presidential Permits
--Alternative 1.

    (a) NEPA Compliance. Except as provided in paragraphs (c) and (e) of 
this section, when an applicant seeks a Presidential Permit, such 
applicant will be responsible for the costs of preparing any necessary 
environmental document, including an Environmental Impact Statement 
(EIS), arising from ERA's obligation to comply with the National 
Environmental Policy Act of 1969 (NEPA). ERA will determine whether an 
environmental assessment (EA) or EIS is required within 45 days of the 
receipt of the Presidential Permit application and of environmental 
information submitted pursuant to 10 CFR 205.322 (c) and (d). ERA will 
use these and other sources of information as the basis for making the 
environmental determination:
    (1) If an EIS is determined to be necessary, the applicant shall 
enter into a contract with an independent third party, which may be a 
Government-owned, contractor-operated National Laboratory, or a 
qualified private entity selected by ERA. The third party contractor 
must be qualified to conduct an environmental review and prepare an EIS, 
as appropriate, under the supervision of ERA, and may not have a 
financial or other interest in the outcome of the proceedings. The NEPA 
process must be completed and approved before ERA will issue a 
Presidential Permit.
    (2) If an EA is determined to be necessary, the applicant may be 
permitted to prepare an environmental assessment pursuant to 10 CFR 
1506.5(b) for review and adoption by ERA, or the applicant may enter 
into a third party contract as set forth in this section.
    (b) Environmental Review Procedure. Except as provided in paragraphs 
(c) and (e) of this section, environmental documents, including the EIS, 
where necessary, will be prepared utilizing the process set forth above. 
ERA, the applicant, and the independent third party, which may be a 
Government-owned, contractor-operated National Laboratory or a private 
entity, shall enter into an agreement in which the applicant will engage 
and pay directly for the services of the qualified third party to 
prepare the necessary environmental documents. The agreement shall 
outline the responsibilities of each party and its relationship to the 
other two parties regarding the work to be done or supervised. ERA shall 
approve the information to be developed and supervise the gathering, 
analysis

[[Page 41]]

and presentation of the information. In addition, ERA will have the 
authority to approve and modify any statement, analysis, and conclusion 
contained in the environmental documents prepared by the third party. 
Before commencing preparation of the environmental document the third 
party will execute an ERA-prepared disclosure document stating that it 
does not have any conflict of interest, financial or otherwise, in the 
outcome of either the environmental process or the Permit application.
    (c) Financial Hardship. Whenever ERA determines that a project is no 
longer economically feasible, or that a substantial financial burden 
would be imposed by the applicant bearing all of the costs of the NEPA 
studies, ERA may waive the requirement set forth in paragraphs (a) and 
(b) of this section and perform the necessary environmental review, 
completely or in part, with its own resources.
    (d) Discussions Prior to Filing. Prior to the preparation of any 
Presidential Permit application and environmental report, a potential 
applicant is encouraged to contact ERA and each affected State public 
utility regulatory agency to discuss the scope of the proposed project 
and the potential for joint State and Federal environmental review.
    (e) Federal Exemption. Upon a showing by the applicant that it is 
engaged in the transaction of official business of the Federal 
Government in filing the application pursuant to 10 CFR 205.320 et seq., 
it will be exempt from the requirements of this section.

[48 FR 33819, July 25, 1983]



Sec. 205.329  Environmental requirements for Presidential Permits
--Alternative 2.

    (a) NEPA Compliance. Except as provided in paragraph (b) and (e) of 
this section, applicants seeking Presidential Permits will be 
financially responsible for the expenses of any contractor chosen by ERA 
to prepare any necessary environmental document arising from ERA's 
obligation to comply with the National Environmental Policy Act of 1969 
(NEPA) in issuing such Presidential Permits:
    (1) ERA will determine whether an Environmental Impact Statement 
(EIS) or an Environmental Assessment (EA) is required within 45 days of 
receipt of the Presidential Permit application and of the environmental 
information submitted pursuant to 10 CFR 205.322 (c) and (d). ERA will 
use these and other sources of information as the basis for making the 
environmental determination.
    (2) If an EIS is determined to be necessary, ERA will notify the 
applicant of the fee for completing the EIS within 90 days after the 
submission of the application and environmental information. The fee 
shall be based on the expenses estimated to be incurred by DOE in 
contracting to prepare the EIS (i.e., the estimated fee charges to ERA 
by the contractor). DOE employee salaries and other fixed costs, as set 
forth in OMB Circular A-25, shall not be included in the applicant's 
fee. Fee payment shall be by check, draft, or money order payable to the 
Treasurer of the United States, and shall be submitted to ERA. Upon 
submission of fifty percent of the environmental fee, ERA will provide 
to the applicant a tentative schedule for completion of the EIS.
    (3) If an EA is determined to be necessary, the applicant may be 
permitted to prepare an environmental assessment pursuant to 40 CFR 
1506.5(b) for review and adoption by ERA, or the applicant may choose to 
have ERA prepare the EA pursuant to the fee procedures set forth above.
    (4) The NEPA process must be completed and approved before ERA will 
issue a Presidential Permit.
    (b) Financial Hardship. Whenever ERA determines that a project is no 
longer economically feasible, or that a substantial financial burden 
would be imposed by the applicant bearing all of the costs of the NEPA 
studies, ERA may waive the requirement set forth in paragraphs (a) and 
(b) of this section and perform the necessary environmental review, 
completely or in part, with its own resources.
    (c) Discussions Prior to Filing. Prior to the preparation of any 
Presidential Permit application and environmental

[[Page 42]]

assessment, a potential applicant is encouraged to contact ERA and each 
affected State public utility regulatory agency to discuss the scope of 
the proposed project and the potential for joint State and Federal 
environmental review.
    (d) Fee Payment. The applicant shall make fee payment for completing 
the EIS to ERA in the following manner:
    (1) 50 percent of the total amount due to be paid within 30 days of 
receipt of the fee information from DOE;
    (2) 25 percent to be paid upon publication of the draft EIS; and
    (3) 25 percent to be paid upon publication of the final EIS.


If costs are less than the amount collected, ERA will refund to the 
applicant the excess fee collected. If costs exceed the initial fee, ERA 
will fund the balance, unless the increase in costs is caused by actions 
or inactions of the applicant, such as the applicant's failure to submit 
necessary environmental information in a timely fashion. If the 
application is withdrawn at any stage prior to issuance of the final 
EIS, the fee will be adjusted to reflect the costs actually incurred; 
payment shall be made by the applicant within 30 days of above 
referenced events.
    (e) Federal Exemption. Upon a showing by the applicant that it is 
engaged in the transaction of official business of the Federal 
Government in filing an application pursuant to 10 CFR 205.320 et seq., 
it will be exempt from the requirements of this section.

Sec. 205.370  Applicability.

    Sections 202(c) and 202(d) of the Federal Power Act are applicable 
to any ``entity'' which owns or operates electric power generation, 
transmission or distribution facilities. An ``entity'' is a private or 
public corporation (utility), a governmental agency, a municipality, a 
cooperative or a lawful association of the foregoing. Under this 
section, the DOE has the authority to order the temporary connection of 
facilities, or the generation or delivery of electricity, which it deems 
necessary to alleviate an emergency. Such orders shall be effective for 
the time specified and will be subject to the terms and conditions the 
DOE specifies. The DOE retains the right to cancel, modify or otherwise 
change any order, with or without notice, hearing, or report. Requests 
for action under these regulations will be accepted from any ``entity,'' 
State Public Utility Commission, State Energy Agency, or State Governor. 
Actions under these regulations also may be initiated by the DOE on its 
own motion. Orders under this authority may be made effective without 
prior notice.



Sec. 205.371  Definition of emergency.

    ``Emergency,'' as used herein, is defined as an unexpected 
inadequate supply of electric energy which may result from the 
unexpected outage or breakdown of facilities for the generation, 
transmission or distribution of electric power. Such events may be the 
result of weather conditions, acts of God, or unforeseen occurrences not 
reasonably within the power of the affected ``entity'' to prevent. An 
emergency also can result from a sudden increase in customer demand, an 
inability to obtain adequate amounts of the necessary fuels to generate 
electricity, or a regulatory action which prohibits the use of certain 
electric power supply facilities. Actions under this authority are 
envisioned as meeting a specific inadequate power supply situation. 
Extended periods of insufficient power supply as a result of inadequate 
planning or the failure to construct necessary facilities can result in 
an emergency as contemplated in these regulations. In such cases, the 
impacted ``entity'' will be expected to make firm arrangements to 
resolve the problem until new facilities become available, so that a 
continuing emergency order is not needed. Situations where a shortage of 
electric energy is projected due solely to the failure of parties to 
agree to terms, conditions or other economic factors relating to 
service, generally will not be considered as emergencies unless the 
inability to supply electric service is imminent. Where an electricity 
outage or service inadequacy qualifies for a section 202(c) order, 
contractual difficulties alone will not be sufficient to preclude the 
issuance of an emergency order.



Sec. 205.372  Filing procedures; number of copies.

    An original and two conformed copies of the applications and reports 
required under Sec. Sec. 205.370 through 205.379 shall be filed with

information as the DOE may deem pertinent.



Sec. 205.374  Responses from ``entities'' designated in the application.

    Each ``entity'' designated as a potential source of emergency 
assistance or as a potential supplier of transmission services and which 
has received a copy of the application under Sec. 205.373, shall have 
three (3) calendar days from the time of receipt of the application to 
file the information designated below with the DOE. The DOE will grant 
extensions of the filing period when appropriate. The designated 
``entities'' shall provide an analysis of the impact the requested 
action would have on its system reliability and its ability to supply 
its own interruptible and firm customers. The effects of the requested 
action on the ability to serve firm loads shall be clearly distinguished 
from the ability to serve contractually interruptible loads. The 
designated ``entity'' also may provide other information relevant to the 
requested action, which is not included in the reliability analysis. 
Copies of any response shall be provided to the applicant, the Federal 
Energy Regulatory Commission, any State Regulatory Agency having 
responsibility for service standards or rates of any ``entity'' that may 
be directly involved in the proposed action, and the appropriate 
Regional Electric Reliability Council. Pursuant to section 202(c) of the 
Federal Power Act, DOE may issue an emergency order even though a 
designated ``entity'' has failed to file a timely response.



Sec. 205.375  Guidelines defining inadequate fuel or energy supply.

    An inadequate utility system fuel inventory or energy supply is a 
matter of managerial and engineering judgment based on such factors as 
fuels in stock, fuels en route, transportation time, and constraints on 
available storage facilities. A system may be considered to have an 
inadequate fuel or energy supply capability when, combined with other 
conditions, the projected energy deficiency upon the applicant's system 
without emergency action by the DOE, will equal or exceed 10 percent of 
the applicant's then normal daily net energy for load, or will cause the 
applicant to be unable to meet its normal peak load requirements based 
upon use of all of its otherwise available resources so that it is 
unable to supply adequate electric service to its ultimate customers. 
The following conditions will be considered in determining that a system 
has inadequate fuel or energy supply capability:
    (1) System coal stocks are reduced to 30 days (or less) of normal 
burn days and a continued downward trend in stock is projected;
    (2) System residual oil stocks are reduced to 15 days (or less) of 
normal burn days and a continued downward trend in stocks is projected;
    (3) System distillate oil stocks which cannot be replaced by 
alternate fuels are reduced to 15 days (or less) of normal burn days and 
a continued downward trend in stocks is projected;
    (4) System natural gas deliveries which cannot be replaced by 
alternate fuels have been or will be reduced 20 percent below normal 
requirements and no improvement in natural gas deliveries is projected 
within 30 days;
    (5) Delays in nuclear fuel deliveries will extend a scheduled 
refueling shutdown by more than 30 days; and
    (6) Water supplies required for power generation have been reduced 
to the level where the future adequacy of the power supply may be 
endangered and no near term improvement in water supplies is projected.


The use of the prescribed criteria does not preclude an applicant from 
claiming the existence of an emergency when its stocks of fuel or water 
exceed the amounts and time frames specified above.



Sec. 205.376  Rates and charges.

    The applicant and the generating or transmitting systems from which 
emergency service is requested are encouraged to utilize the rates and 
charges contained in approved existing rate schedules or to negotiate 
mutually satisfactory rates for the proposed

[[Page 47]]

transactions. In the event that the DOE determines that an emergency 
exists under section 202(c), and the ``entities'' are unable to agree on 
the rates to be charged, the DOE shall prescribe the conditions of 
service and refer the rate issues to the Federal Energy Regulatory 
Commission for determination by that agency in accordance with its 
standards and procedures.



Sec. 205.377  Reports.

    In addition to the information specified below, the DOE may require 
additional reports as it deems necessary.
    (a) Where the DOE has authorized the temporary connection of 
transmission facilities, all ``entities'' whose transmission facilities 
are thus temporarily interconnected shall report the following 
information to the DOE within 15 days following completion of the 
interconnection:
    (1) The date the temporary interconnection was completed;
    (2) The location of the interconnection;
    (3) A description of the interconnection; and
    (4) A one-line electric diagram of the interconnection.
    (b) Where the DOE orders the transfer of power, the ``entity'' 
receiving such service shall report the following information to the DOE 
by the 10th of each month for the preceding month's activity for as long 
as such order shall remain in effect:
    (1) Amounts of capacity and/or energy received each day;
    (2) The name of the supplier;
    (3) The name of any ``entity'' supplying transmission services; and
    (4) Preliminary estimates of the associated costs.
    (c) Where the DOE has approved the installation of permanent 
facilities that will be used only during emergencies, any use of such 
facilities shall be reported to the DOE within 24 hours. Details of such 
usage shall be furnished as deemed appropriate by the DOE after such 
notification.
    (d) Any substantial change in the information provided under Sec. 
205.373 shall be promptly reported to the DOE.

Sec. 205.378  Disconnection of temporary facilities.

    Upon the termination of any emergency for the mitigation of which 
the DOE ordered the construction of temporary facilities, such 
facilities shall be disconnected and any temporary construction removed 
or otherwise disposed of, unless application is made as provided in 
Sec. 205.379 for permanent connection for emergency use. This 
disconnection and removal of temporary facilities shall be accomplished 
within 30 days of the termination of the emergency unless an extension 
is granted by the DOE. The DOE shall be notified promptly when such 
removal of facilities is completed.



Sec. 205.379  Application for approval of the installation of 
permanent facilities for emergency use only.

    Application for DOE approval of a permanent connection for emergency 
use only shall conform with the requirements in Sec. 205.373. However, 
the baseline data specified in Sec. 205.373(d) need not be included in 
an application made under this section. In addition, the application 
shall state in full the reasons why such permanent connection for 
emergency use is in the public interest.

information under this subpart, he may specify (in the rule, order or 
questionnaire or other means by which he has requested such reports) the 
nature of the showing required to be made in order to satisfy DOE that 
certain energy information contained in such reports warrants 
confidential treatment in accordance with this section. He shall, to the 
maximum extent practicable, either before or after requesting reports, 
by ruling or otherwise, inform respondents providing energy information 
pursuant to this subpart of whether such information will be made 
available to the public pursuant to requests under the Freedom of

Sec. 207.5  Violations.

    Any practice that circumvents or contravenes or results in a 
circumvention or contravention of the requirements of any provision of 
this subpart or any order issued pursuant thereto is a violation of the 
DOE regulations stated in this subpart.



Sec. 207.6  Notice of probable violation and remedial order.

    (a) Purpose and scope. (1) This section establishes the procedures 
for determining the nature and extent of violations of this subpart and 
the procedures for issuance of a notice of probable violation, a 
remedial order or a remedial order for immediate compliance.
    (2) When the DOE discovers that there is reason to believe a 
violation of any provision of this subpart, or any order issued 
thereunder, has occurred, is continuing or is about to occur, the DOE 
may conduct proceedings to determine the nature and extent of the 
violation and may issue a remedial order thereafter. The DOE may 
commence such proceeding by serving a notice of probable violation or by 
issuing a remedial order for immediate compliance.
    (b) Notice of probable violation. (1) The DOE may begin a proceeding 
under this subpart by issuing a notice of probable violation if the DOE 
has reason to believe that a violation has occurred, is continuing, or 
is about to occur.

[[Page 50]]

    (2) Within 10 days of the service of a notice of probable violation, 
the person upon whom the notice is served may file a reply with the DOE 
office that issued the notice of probable violation at the address 
provided in Sec. 205.12 of this chapter. The DOE may extend the 10-day 
period for good cause shown.
    (3) The reply shall be in writing and signed by the person filing 
it. The reply shall contain a full and complete statement of all 
relevant facts pertaining to the act or transaction that is the subject 
of the notice of probable violation. Such facts shall include a complete 
statement of the business or other reasons that justify the act or 
transaction, it appropriate; a detailed description of the act or 
transaction; and a full discussion of the pertinent provisions and 
relevant facts reflected in any documents submitted with the reply. 
Copies of all relevant documents shall be submitted with the reply.
    (4) The reply shall include a discussion of all relevant 
authorities, including, but not limited to, DOE rulings, regulations, 
interpretations, and decisions on appeals and exceptions relied upon to 
support the particular position taken.
    (5) The reply should indicate whether the person requests or intends 
to request a conference regarding the notice. Any request not made at 
the time of the reply shall be made as soon thereafter as possible to 
insure that the conference is held when it will be most beneficial. A 
request for a conference must conform to the requirements of subpart M 
of part 205 of this chapter.
    (6) If a person has not filed a reply with the DOE within the 10-day 
period provided, and the DOE has not extended the 10-day period, the 
person shall be deemed to have conceded the accuracy of the factual 
allegations and legal conclusions stated in the notice of probable 
violation.
    (7) If the DOE finds, after the 10-day period provided in Sec. 
207.6(b)(2), that no violation has occurred, is continuing, or is about 
to occur, or that for any reason the issuance of a remedial order would 
not be appropriate, it shall notify, in writing, the person to whom a 
notice of probable violation has been issued that the notice is 
rescinded.
    (c) Remedial order. (1) If the DOE finds, after the 10-day period 
provided in Sec. 207.6(b)(2), that a violation has occurred, is 
continuing, or is about to occur, the DOE may issue a remedial order. 
The order shall include a written opinion setting forth the relevant 
facts and the legal basis of the remedial order.
    (2) A remedial order issued under this subpart shall be effective 
upon issuance, in accordance with its terms, until stayed, suspended, 
modified or rescinded. The DOE may stay, suspend, modify or rescind a 
remedial order on its own initiative or upon application by the person 
to whom the remedial order is issued. Such action and application shall 
be in accordance with the procedures for such proceedings provided for 
in part 205 of this chapter.
    (3) A remedial order may be referred at any time to the Department 
of Justice for appropriate action in accordance with Sec. 207.7.
    (d) Remedial order for immediate compliance. (1) Notwithstanding 
paragraphs (b) and (c) of this section, the DOE may issue a remedial 
order for immediate compliance, which shall be effective upon issuance 
and until rescinded or suspended, if it finds:
    (i) There is a strong probability that a violation has occurred, is 
continuing or is about to occur;
    (ii) Irreparable harm will occur unless the violation is remedied 
immediately; and
    (iii) The public interest requires the avoidance of such irreparable 
harm through immediate compliance and waiver of the procedures afforded 
under paragraphs (b) and (c) of this section.
    (2) A remedial order for immediate compliance shall be served 
promptly upon the person against whom such order is issued by telex or 
telegram, with a copy served by registered or certified mail. The copy 
shall contain a written statement of the relevant facts and the legal 
basis for the remedial order for immediate compliance, including the 
findings required by paragraph (d)(1) of this section.
    (3) The DOE may rescind or suspend a remedial order for immediate 
compliance if it appears that the criteria set forth in paragraph (d)(1) 
of this section

[[Page 51]]

are no longer satisfied. When appropriate, however, such a suspension or 
rescission may be accompanied by a notice of probable violation issued 
under paragraph (b) of this section.
    (4) If at any time in the course of a proceeding commenced by a 
notice of probable violation the criteria set forth in paragraph (d)(1) 
of this section are satisfied, the DOE may issue a remedial order for 
immediate compliance, even if the 10-day period for reply specified in 
Sec. 207.6(b)(2) of this part has not expired.
    (5) At any time after a remedial order for immediate compliance has 
become effective the DOE may refer such order to the Department of 
Justice for appropriate action in accordance with Sec. 207.7 of this 
part.
    (e) Remedies. A remedial order or a remedial order for immediate 
compliance may require the person to whom it is directed to take such 
action as the DOE determines is necessary to eliminate or to compensate 
for the effects of a violation.
    (f) Appeal. (1) No notice of probable violation issued pursuant to 
this subpart shall be deemed to be an action of which there may be an 
administrative appeal.
    (2) Any person to whom a remedial order or a remedial order for 
immediate compliance is issued under this subpart may file an appeal 
with the DOE Office of Exceptions and Appeals in accordance with the 
procedures for such appeal provided in subpart H of part 205 of this 
chapter. The appeal must be filed within 10 days of service of the order 
from which the appeal is taken.



Sec. 207.7  Sanctions.

    (a) General. (1) Penalties and sanctions shall be deemed cumulative 
and not mutually exclusive.
    (2) Each day that a violation of the provisions of this subpart or 
any order issued pursuant thereto continues shall be deemed to 
constitute a separate violation within the meaning of the provisions of 
this subpart relating to criminal fines and civil penalties.
    (b) Criminal penalties. Any person who willfully violates any 
provision of this subpart or any order issued pursuant thereto shall be 
subject to a fine of not more than $5,000 for each violation. Criminal 
violations are prosecuted by the Department of Justice upon referral by 
the DOE.
    (c) Civil Penalties. (1) Any person who violates any provision of 
this subpart or any order issued pursuant thereto shall be subject to a 
civil penalty of not more than $10,164 for each violation. Actions for 
civil penalties are prosecuted by the Department of Justice upon 
referral by the DOE.
    (2) When the DOE considers it to be appropriate or advisable, the 
DOE may compromise and settle, and collect civil penalties.

Sec. 207.8  Judicial actions.

    (a) Enforcement of subpoenas; contempt. Any United States district 
court within the jurisdiction of which any inquiry is carried on may, 
upon petition by the Attorney General at the request of the 
Administrator, in the case of refusal to obey a subpoena or order of the 
Administrator issued under this subpart, issue an order requiring 
compliance. Any failure to obey such an order of the court may be 
punished by the court as contempt.
    (b) Injunctions. Whenever it appears to the Administrator that any 
person has engaged, is engaged, or is about to engage in any act or 
practice constituting a violation of any regulation or order issued 
under this subpart, the Administrator may request the Attorney General 
to bring a civil action in the appropriate district court of the United 
States to enjoin such acts or practices and, upon a proper showing, a 
temporary restraining order or preliminary or permanent injunction shall 
be granted without bond. The relief sought may include a mandatory 
injunction commanding any person to comply with any provision of such 
order or regulation, the violation of which is prohibited by section 
12(a) of ESECA, as implemented by this subpart.

records and transcripts prepared pursuant to paragraphs (a) and (b) of 
this section, shall be deposited within seven (7) days after the close 
of the week (ending Saturday) of their preparation during an 
international energy supply emergency or a test of the IEA emergency 
allocation system, and within fifteen (15) days after the close of the 
month of their preparation during periods of non-emergency, together 
with any agreement resulting therefrom, with the Department of Energy 
and shall be available to the Department of Justice, the Federal Trade 
Commission, and the Department of State. Such records and transcripts

out a plan of action shall, if not otherwise required to be recorded 
pursuant to this section, be recorded by such official as provided in 
Sec. 204.5.
    (e) During international oil allocation under chapters III and IV of

                         Subpart A_Recordkeeping



Sec. 210.1  Records.

    (a) The recordkeeping requirements that were in effect on January 
27, 1981, in parts 210, 211, and 212 will remain in effect for (1) all 
transactions prior to February 1, 1981; and (2) all allowed expenses 
incurred and paid prior to April 1, 1981 under Sec. 212.78 of part 212. 
These requirements include, but are not limited to, the requirements 
that were in effect on January 27, 1981, in Sec. 210.92 of this part; 
in Sec. Sec. 211.67(a)(5)(ii); 211.89; 211.109, 211.127; and 211.223 of 
part 211; and in Sec. Sec. 212.78(h)(5)(ii); 212.78(h)(6); 
212.83(c)(2)(iii)(E)(I); 212.83(c)(2)(iii)(E)(II); 212.83(c)(2)(iii); 
``Fi t''; 212.83(i); 212.93(a); 212.93(b)(4)(iii)(B)(I); 
212.93(i)(4); 212.94(b)(2)(iii); 212.128; 212.132; 212.172; and Sec. 
212.187 of part 212.
    (b) Effective February 5, 1985, paragraph (a) of this section shall 
apply, to the extent indicated, only to firms in the following 
categories. A firm may be included in more than one category, and a firm 
may move from one category to another. The fact that a firm becomes no 
longer subject to the recordkeeping requirements of one category shall 
not relieve that firm of compliance with the recordkeeping requirements 
of any other category in which the firm is still included.
    (1) Those firms which are or become parties in litigation with DOE, 
as defined in paragraph (c)(1) of this section. Any such firm shall 
remain subject to paragraph (a) of this section. DOE shall notify the 
firm in writing of the final resolution of the litigation and whether or 
not any of its records must be maintained for a further period. DOE 
shall notify a firm which must maintain any records for a further period 
when such records are no longer needed.
    (2)(i) Those firms which as of November 30 1984, have completed 
making all restitutionary payments required by an administrative or 
judicial order, consent order, or other settlement or order but which 
payments are on February 5, 1985, still subject to distribution by DOE. 
This requirement is applicable to only those firms listed in appendix B. 
Any such firm shall maintain all records for the time period covered by 
the administrative or judicial order, consent order, or other settlement 
or order requiring the payments, evidencing sales volume data for each 
product subject to controls and customers' names and addresses, until 
one of the following: June 30, 1985, unless this period is extended on a 
firm-by-firm basis; the end of the individual firm's extension; or the 
firm is notified in writing that its records are no longer needed.
    (ii) Those firms which as of November 30, 1984, are required to make 
restitutionary or other payments pursuant to an administrative or 
judicial order, consent order, or other settlement or order. Any such 
firm shall remain subject to paragraph (a) of this section until the 
firm completes all restitutionary payments required by the 
administrative or judicial order, consent order, or other settlement or 
order. However, after completing all such payments, a firm shall 
maintain

[[Page 58]]

all records described in paragraph (b)(2)(i) of this section until one 
of the following: Six months after the firm completes all such payments, 
unless this period is extended on a firm-by-firm basis; the end of the 
individual firm's extension; or the firm is notified in writing that its 
records are no longer needed.
    (3)(i) Those firms with completed audits in which DOE has not yet 
made a determination to initiate a formal enforcement action and firms 
under audit which do not have outstanding subpoenas. Any such firm shall 
maintain all records for the period covered by the audit including all 
records necessary to establish historical prices or volumes which serve 
as the basis for determining the lawful prices or volumes for any 
subsequent regulated transaction which is subject to audit, until one of 
the following: June 30, 1985, unless this period is extended on a firm-
by-firm basis; the end of the individual firm's extension; or the firm 
is notified in writing by DOE that its records are no longer needed. 
However, if a firm in this group shall become a party in litigation, the 
firm shall then be subject to the recordkeeping requirements for firms 
in litigation set forth in paragraph (b)(1) of this section.
    (ii) Those firms under audit which have outstanding subpoenas on 
February 5, 1985, or which receive subpoenas at any time thereafter or 
which have supplied records for an audit as the result of a subpoena 
enforced after November 1, 1983. Any such firm shall remain subject to 
paragraph (a) of this section until two years after ERA has notified the 
firm in writing that is in full compliance with the subpoena or until 
ERA has received from the firm a sworn certification of compliance with 
the subpoena as required by 10 CFR 205.8. However, if a firm in this 
group shall become a party in litigation, the firm shall then be subject 
to the recordkeeping requirements for firms in litigation set forth in 
paragraph (b)(1) of this section.
    (4) Those firms which are subject to requests for data necessary to 
verify that crude oil qualifies as ``newly discovered'' crude oil under 
10 CFR 212.79. Any such firm shall maintain the records evidencing such 
data until one of the following: June 30, 1985, unless this period is 
extended on a firm-by-firm basis; the end of an individual firm's 
extension; or the firm is notified in writing by DOE that its records 
are no longer needed. However, if a firm in this group shall become a 
party in litigation, the firm shall then be subject to the recordkeeping 
requirements for firms in litigation set forth in paragraph (b)(1) of 
this section.
    (5) Those firms whose records are determined by DOE as necessary to 
complete the enforcement activity relating to another firm which is also 
subject to paragraph (a) of this section unless such firms required to 
keep records have received certified notice letters specifically 
describing the records determined as necessary. At that time, the 
specific notice will control the recordkeeping requirements. These firms 
have been identified in appendix A. Any such firm shall maintain these 
records until one of the following: June 30, 1985, unless this period is 
extended on a firm-by-firm basis; the end of the individual firm's 
extension; or the firm is notified in writing by DOE that its records 
are no longer needed.
    (6) Those firms which participated in the Entitlements program. Any 
such firm shall maintain its Entitlements-related records until six 
months after the final judicial resolution (including any and all 
appeals) of Texaco v. DOE, Nos. 84-391, 84-410, and 84-456 (D. Del.), or 
the firm is notified by DOE that its records are no longer needed, 
whichever occurs first.
    (c) For purposes of this section:
    (1) A firm is ``a party in litigation'' if:
    (i)(A) The firm has received a Notice of Probable Violation, a 
Notice of Probable Disallowance, a Proposed Remedial Order, or a 
Proposed Order of Disallowance; or
    (B) The firm and DOE are parties in a lawsuit arising under the 
Emergency Petroleum Allocation Act of 1973, as amended (15 U.S.C. 751 et 
seq.) or 10 CFR parts 205, 210, 211, or 212; and
    (ii)(A) There has been no final (that is, non-appealable) 
administrative or judicial resolution, or
    (B) DOE has not informed the firm in writing that the Department has 
completed its review of the matter.

[[Page 59]]

    (2) A firm means any association, company, corporation, estate, 
individual, joint-venture, partnership, or sole proprietorship, or any 
other entity, however organized, including charitable, educational, or 
other eleemosynary institutions, and state and local governments. A firm 
includes a parent and the consolidated and unconsolidated entities (if 
any) which it directly or indirectly controls.

    Source: 43 FR 6212, Feb. 14, 1978, unless otherwise noted.



Sec. 216.1  Introduction.

    (a) This part describes and establishes the procedures to be used by 
the Department of Energy (DOE) in considering and making certain 
findings required by section 101(c)(2)(A) of the Defense Production Act 
of 1950, as amended, 50 U.S.C. app. 2071(c)(2)(A) (DPA). Section 101(c) 
authorizes the allocation of, or priority performance under contracts or 
orders (other than contracts of employment) relating to, materials and 
equipment, services, or facilities in order to maximize domestic energy 
supplies if the findings described in section 101(c)(2) are made. Among 
these findings are that such supplies of materials and equipment, 
services, or facilities are critical and essential to maintain or 
further exploration, production, refining, transportation or the 
conservation of energy supplies or for the construction or maintenance 
of energy facilities. The function of finding that supplies are critical 
and essential was delegated to the Secretary of Energy pursuant to E.O. 
12919 (59 FR 29525, June 7, 1994) and Department of Commerce Defense 
Priorities and Allocations System Delegation No. 2, 15 CFR part 700.
    (b) The purpose of these regulations is to establish the procedures 
and criteria to be used by DOE in determining whether programs or 
projects maximize domestic energy supplies and whether or not supplies 
of materials and equipment, services, or facilities are critical and 
essential, as required by DPA section 101(c)(2)(A). The critical and 
essential finding will be made only for supplies of materials and 
equipment, services, or facilities related to those programs or projects 
determined by DOE to maximize domestic energy supplies. These 
regulations

[[Page 67]]

do not require or imply that the findings, on which the exercise of such 
authority is conditioned, will be made in any particular case.
    (c) If DOE determines that a program or project maximizes domestic 
energy supplies and finds that supplies of materials and equipment, 
services, or facilities are critical and essential to maintain or 
further the exploration, production, refining, transportation or 
conservation of energy supplies or for the construction or maintenance 
of energy facilities, such determination and finding will be 
communicated to the Department of Commerce (DOC). If not, the applicant 
will be so informed. If the determination and finding described in this 
paragraph are made, DOC, pursuant to DPA section 101(c) and section 203 
of E.O. 12919, will find whether or not: The supplies of materials and 
equipment, services, or facilities in question are scarce; and 
maintenance or furtherance of exploration, production, refining, 
transportation, or conservation of energy supplies or the construction 
or maintenance of energy facilities cannot be reasonably accomplished 
without exercising the authority specified in DPA section 101(c). If 
these additional two findings are made, DOC will notify DOE, and DOE 
will inform the applicant that it has been granted the right to use 
priority ratings under the Defense Priorities and Allocations System 
(DPAS) regulation established by the DOC, 15 CFR part 700.

FR 10983, Feb. 29, 2008]



Sec. 216.4  Evaluation by DOE of applications.

    (a) Based on the information provided by the applicant and other 
available information, DOE will:

[[Page 69]]

    (1) Determine whether or not the energy program or project in 
connection with which the application is made maximizes domestic energy 
supplies and should be designated an eligible energy program or project; 
and
    (2) Find whether the described supplies of materials and equipment, 
services, or facilities are critical and essential to the eligible 
energy program or project.
    (b) In determining whether the program or project referred to in the 
application should be designated an eligible energy program or project, 
DOE will consider all factors which it considers relevant including, but 
not limited to, the following:
    (1) Quantity of energy involved;
    (2) Benefits of timely energy program furtherance or project 
completion;
    (3) Socioeconomic impact;
    (4) The need for the end product for which the materials and 
equipment, services, or facilities are allegedly required; and
    (5) Established national energy policies.
    (c) In finding whether the supplies of materials and equipment, 
services, or facilities described in the application are critical and 
essential to an eligible energy program or project, DOE will consider 
all factors which it considers relevant including, but not limited to, 
the following:
    (1) Availability and utility of substitute materials and equipment, 
services, or facilities; and
    (2) Impact of the nonavailability of the specific supplies of 
materials and equipment, services, or facilities on the furtherance or 
timely completion of the approved energy program or project.
    (d) Increased costs which may be associated with obtaining materials 
and equipment, services, or facilities without assistance shall not be 
considered a valid reason for finding the materials and equipment, 
services, or facilities to be critical and essential.
    (e) After DOE has determined a program or project to be an eligible 
energy program or project, this determination shall be deemed made with 
regard to subsequent applications involving the same program or project 
unless and until DOE announces otherwise.

[43 FR 6212, Feb. 14, 1978, as amended at 73 FR 10984, Feb. 29, 2008]



Sec. 216.5  Notification of findings.

    (a) DOE will notify DOC if it finds that supplies of materials and 
equipment, services, or facilities for which an applicant requested 
assistance are critical and essential to an eligible energy program or 
project, and in such cases will forward to DOC the application and 
whatever information or comments DOE believes appropriate. If DOE 
believes at any time that findings previously made may no longer be 
valid, it will immediately notify the DOC and the affected applicant(s) 
and afford such applicant(s) an opportunity to show cause why such 
findings should not be withdrawn.
    (b) If DOC notifies DOE that DOC has found that supplies of 
materials and equipment, services, or facilities for which the applicant 
requested assistance are scarce and that the related eligible energy 
program or project cannot reasonably be accomplished without exercising 
the authority specified in DPA section 101(c)(1), DOE will notify the 
applicant that the applicant is authorized to place rated orders for 
specific materials and equipment, services, or facilities pursuant to 
the provisions of the DOC's DPAS regulation.

[73 FR 10984, Feb. 29, 2008]



Sec. 216.6  Petition for reconsideration.

    If DOE, after evaluating an application in accordance with Sec. 
216.4, does not determine that the energy program or project maximizes 
domestic energy supplies or does not find that the supplies of materials 
and equipment, services, or facilities described in the application are 
critical and essential to an eligible energy program or project, it will 
so notify the applicant and the applicant may petition DOE for 
reconsideration. If DOE concludes at any time that findings previously 
made are no longer valid and should be withdrawn, DOE will so notify the 
affected applicant(s), and such applicant(s) may petition DOE for 
reconsideration of the withdrawal decision. A petition is deemed 
accepted when received by DOE

[[Page 70]]

at the address stated in Sec. 216.8. DOE will consider the petition for 
reconsideration and either grant or deny the relief requested. Written 
notice of the decision and of the reasons for the decision will be 
provided to the applicant. There has not been an exhaustion of 
administrative remedies until a petition for reconsideration has been 
submitted and the review procedure completed by grant or denial of the 
relief requested. The denial of relief requested in a petition for 
reconsideration is a final administrative decision.

Sec. 217.1  Purpose of this part.

    This part provides guidance and procedures for use of the Defense 
Production Act section 101(a) priorities and allocations authority with 
respect to all forms of energy necessary or appropriate to promote the 
national defense. (The guidance and procedures in this part are 
consistent with the guidance and procedures provided in other 
regulations that, as a whole, form the Federal Priorities and 
Allocations System. Guidance and procedures for use of the Defense 
Production Act priorities and allocations authority with respect to 
other types of resources are provided for: Food resources, food resource 
facilities, and the domestic distribution of farm equipment and 
commercial fertilizer; health resources; all forms of civil 
transportation (49 CFR Part 33); water resources; and all other 
materials, services, and facilities, including construction materials in 
the Defense Priorities and Allocations System (DPAS) regulation (15 CFR 
Part 700).) Department of Energy (DOE) regulations at 10 CFR Part 216 
describe and establish the procedures to be used by DOE in considering 
and making certain findings required by section 101(c)(2)(A) of the 
Defense Production Act of 1950, as amended.



Sec. 217.2  Priorities and allocations authority.

    (a) Section 201 of E.O. 12919 (59 FR 29525) delegates the 
President's authority under section 101 of the Defense Production Act to 
require acceptance and priority performance of contracts and orders 
(other than contracts of employment) to promote the national defense 
over performance of any other contracts or orders, and to allocate 
materials, services, and facilities as deemed necessary or appropriate 
to promote the national defense to:
    (1) The Secretary of Agriculture with respect to food resources, 
food resource facilities, and the domestic distribution of farm 
equipment and commercial fertilizer;
    (2) The Secretary of Energy with respect to all forms of energy;
    (3) The Secretary of Health and Human Services with respect to

civil transportation;
    (5) The Secretary of Defense with respect to water resources; and
    (6) The Secretary of Commerce for all other materials, services, and 
facilities, including construction materials.
    (b) Section 202 of E.O. 12919 states that the priorities and 
allocations authority delegated in section 201 of this order may be used 
only to support programs that have been determined in writing as 
necessary or appropriate to promote the national defense:
    (1) By the Secretary of Defense with respect to military production 
and construction, military assistance to foreign nations, stockpiling, 
outer space, and directly related activities;
    (2) By the Secretary of Energy with respect to energy production and 
construction, distribution and use, and directly related activities; and
    (3) By the Secretary of Homeland Security with respect to essential 
civilian needs supporting national defense, including civil defense and 
continuity of government and directly related activities.

[[Page 75]]



                   Subpart C_Placement of Rated Orders



Sec. 217.30  Delegations of authority.

    (a) The priorities and allocations authorities of the President 
under Title I of the Defense Production Act with respect to all forms of 
energy have been delegated to the Secretary of Energy under E.O. 12919 
of June 3, 1994 (59 FR 29525).
    (b) The Department of Commerce has delegated authority to the 
Department of Energy to provide for extension of priority ratings for 
``industrial resources,'' as provided in Sec. 261.35 of this part, to 
support rated orders for all forms of energy.



Sec. 217.31  Priority ratings.

    (a) Levels of priority.
    (1) There are two levels of priority established by the Energy 
Priorities and Allocations System regulations, identified by the rating 
symbols ``DO'' and ``DX''.
    (2) All DO-rated orders have equal priority with each other and take 
precedence over unrated orders. All DX-rated orders have equal priority 
with each other and take precedence over DO-rated orders and unrated 
orders. (For resolution of conflicts among rated orders of equal 
priority, see Sec. 217.34(c).)
    (3) In addition, a Directive regarding priority treatment for a 
given item issued by the Department of Energy for that item takes 
precedence over any DX-rated order, DO-rated order, or unrated order, as 
stipulated in the Directive. (For a full discussion of Directives, see 
Sec. 217.62.)
    (b) Program identification symbols. Program identification symbols 
indicate which approved program is being supported by a rated order. The 
list of currently approved programs and their identification symbols are 
listed in Schedule 1, set forth as an appendix to 15 CFR part 700. For 
example, DO-F3 identifies a domestic energy construction program. 
Additional programs may be approved under the procedures of E.O. 12919 
at any time. Program identification symbols do not connote any priority.
    (c) Priority ratings. A priority rating consists of the rating 
symbol--DO or DX--and the program identification symbol, such as F1, F2, 
or F3. Thus, a contract for a domestic energy construction program will 
contain a DO-F3 or DX-F3 priority rating.



Sec. 217.32  Elements of a rated order.

    Each rated order must include:
    (a) The appropriate priority rating (e.g. DO-F1 or DX-F1)
    (b) A required delivery date or dates. The words ``immediately'' or 
``as soon as possible'' do not constitute a delivery date. A 
``requirements contract'', ``basic ordering agreement'', ``prime vendor 
contract'', or similar procurement document bearing a priority rating 
may contain no specific delivery date or dates and may provide for the 
furnishing of items or service from time to time or within a stated 
period against specific purchase orders, such as ``calls'', 
``requisitions'', and ``delivery orders''. These purchase orders must 
specify a required delivery date or dates and are to be considered as 
rated as of the date of their receipt by the supplier and not as of the 
date of the original procurement document;
    (c) The written signature on a manually placed order, or the digital 
signature or name on an electronically placed order, of an individual 
authorized to sign rated orders for the person placing the order. The 
signature or use of the name certifies that the rated order is 
authorized under this part and that the requirements of this part are 
being followed; and
    (d)(1) A statement that reads in substance:
    This is a rated order certified for national defense use, and you 
are required to follow all the provisions of the Energy Priorities and 
Allocations System regulation at 10 CFR part 217.
    (2) If the rated order is placed in support of emergency 
preparedness requirements and expedited action is necessary and 
appropriate to meet these requirements, the following sentences should 
be added following the statement set forth in paragraph (d)(1) of this 
section:
    This rated order is placed for the purpose of emergency 
preparedness. It must be accepted or rejected within 2 days after 
receipt of the order if (1) The

[[Page 76]]

order is issued in response to a hazard that has occurred; or
    (2) If the order is issued to prepare for an imminent hazard, as 
specified in EPAS Section 217.33(e), 10 CFR 217.33(e).



Sec. 217.33  Acceptance and rejection of rated orders.

    (a) Mandatory acceptance. (1) Except as otherwise specified in this 
section, a person shall accept every rated order received and must fill 
such orders regardless of any other rated or unrated orders that have 
been accepted.
    (2) A person shall not discriminate against rated orders in any 
manner such as by charging higher prices or by imposing different terms 
and conditions than for comparable unrated orders.
    (b) Mandatory rejection. Unless otherwise directed by the Department 
of Energy for a rated order involving all forms of energy:
    (1) A person shall not accept a rated order for delivery on a 
specific date if unable to fill the order by that date. However, the 
person must inform the customer of the earliest date on which delivery 
can be made and offer to accept the order on the basis of that date. 
Scheduling conflicts with previously accepted lower rated or unrated 
orders are not sufficient reason for rejection under this section.
    (2) A person shall not accept a DO-rated order for delivery on a 
date which would interfere with delivery of any previously accepted DO- 
or DX-rated orders. However, the person must offer to accept the order 
based on the earliest delivery date otherwise possible.
    (3) A person shall not accept a DX-rated order for delivery on a 
date which would interfere with delivery of any previously accepted DX-
rated orders, but must offer to accept the order based on the earliest 
delivery date otherwise possible.
    (4) If a person is unable to fill all of the rated orders of equal 
priority status received on the same day, the person must accept, based 
upon the earliest delivery dates, only those orders which can be filled, 
and reject the other orders. For example, a person must accept order A 
requiring delivery on December 15 before accepting order B requiring 
delivery on December 31. However, the person must offer to accept the 
rejected orders based on the earliest delivery dates otherwise possible.
    (c) Optional rejection. Unless otherwise directed by the Department 
of Energy for a rated order involving all forms of energy, rated orders 
may be rejected in any of the following cases as long as a supplier does 
not discriminate among customers:
    (1) If the person placing the order is unwilling or unable to meet 
regularly established terms of sale or payment;
    (2) If the order is for an item not supplied or for a service not 
capable of being performed;
    (3) If the order is for an item or service produced, acquired, or 
provided only for the supplier's own use for which no orders have been 
filled for two years prior to the date of receipt of the rated order. 
If, however, a supplier has sold some of these items or provided similar 
services, the supplier is obligated to accept rated orders up to that 
quantity or portion of production or service, whichever is greater, sold 
or provided within the past two years;
    (4) If the person placing the rated order, other than the U.S. 
Government, makes the item or performs the service being ordered;
    (5) If acceptance of a rated order or performance against a rated 
order would violate any other regulation, official action, or order of 
the Department of Energy, issued under the authority of the Defense 
Production Act or another relevant statute.
    (d) Customer notification requirements. (1) Except as provided in 
this paragraph, a person must accept or reject a rated order in writing 
or electronically within fifteen (15) working days after receipt of a DO 
rated order and within ten (10) working days after receipt of a DX rated 
order. If the order is rejected, the person must give reasons in writing 
or electronically for the rejection.
    (2) If a person has accepted a rated order and subsequently finds 
that shipment or performance will be delayed, the person must notify the 
customer immediately, give the reasons for the delay, and advise of a 
new shipment or performance date. If notification is

[[Page 77]]

given verbally, written or electronic confirmation must be provided 
within five (5) working days.
    (e) Exception for emergency preparedness conditions. If the rated 
order is placed for the purpose of emergency preparedness, a person must 
accept or reject a rated order and transmit the acceptance or rejection 
in writing or in an electronic format within 2 days after receipt of the 
order if:
    (1) The order is issued in response to a hazard that has occurred; 
or
    (2) The order is issued to prepare for an imminent hazard.



Sec. 217.34  Preferential scheduling.

    (a) A person must schedule operations, including the acquisition of 
all needed production items or services, in a timely manner to satisfy 
the delivery requirements of each rated order. Modifying production or 
delivery schedules is necessary only when required delivery dates for 
rated orders cannot otherwise be met.
    (b) DO-rated orders must be given production preference over unrated 
orders, if necessary to meet required delivery dates, even if this 
requires the diversion of items being processed or ready for delivery or 
services being performed against unrated orders. Similarly, DX-rated 
orders must be given preference over DO-rated orders and unrated orders. 
(Examples: If a person receives a DO-rated order with a delivery date of 
June 3 and if meeting that date would mean delaying production or 
delivery of an item for an unrated order, the unrated order must be 
delayed. If a DX-rated order is received calling for delivery on July 15 
and a person has a DO-rated order requiring delivery on June 2 and 
operations can be scheduled to meet both deliveries, there is no need to 
alter production schedules to give any additional preference to the DX-
rated order.)
    (c) Conflicting rated orders.
    (1) If a person finds that delivery or performance against any 
accepted rated orders conflicts with the delivery or performance against 
other accepted rated orders of equal priority status, the person shall 
give precedence to the conflicting orders in the sequence in which they 
are to be delivered or performed (not to the receipt dates). If the 
conflicting orders are scheduled to be delivered or performed on the 
same day, the person shall give precedence to those orders that have the 
earliest receipt dates.
    (2) If a person is unable to resolve rated order delivery or 
performance conflicts under this section, the person should promptly 
seek special priorities assistance as provided in Sec. Sec. 217.40 
through 217.44. If the person's customer objects to the rescheduling of 
delivery or performance of a rated order, the customer should promptly 
seek special priorities assistance as provided in Sec. Sec. 217.40 
through 217.44. For any rated order against which delivery or 
performance will be delayed, the person must notify the customer as 
provided in Sec. 217.33.
    (d) If a person is unable to purchase needed production items in 
time to fill a rated order by its required delivery date, the person 
must fill the rated order by using inventoried production items. A 
person who uses inventoried items to fill a rated order may replace 
those items with the use of a rated order as provided in Sec. 
217.37(b).



Sec. 217.35  Extension of priority ratings.

    (a) A person must use rated orders with suppliers to obtain items or 
services needed to fill a rated order. The person must use the priority 
rating indicated on the customer's rated order, except as otherwise 
provided in this part or as directed by the Department of Energy. For 
example, if a person is in receipt of a DO-F1 rated order for an 
electric power sub-station, and needs to purchase a transformer for its 
manufacture, that person must use a DO-F1 rated order to obtain the 
needed transformer.
    (b) The priority rating must be included on each successive order 
placed to obtain items or services needed to fill a customer's rated 
order. This continues from contractor to subcontractor to supplier 
throughout the entire procurement chain.



Sec. 217.36  Changes or cancellations of priority ratings and rated 
orders.

    (a) The priority rating on a rated order may be changed or canceled 
by:

[[Page 78]]

    (1) An official action of the Department of Energy; or
    (2) Written notification from the person who placed the rated order.
    (b) If an unrated order is amended so as to make it a rated order, 
or a DO rating is changed to a DX rating, the supplier must give the 
appropriate preferential treatment to the order as of the date the 
change is received by the supplier.
    (c) An amendment to a rated order that significantly alters a 
supplier's original production or delivery schedule shall constitute a 
new rated order as of the date of its receipt. The supplier must accept 
or reject the amended order according to the provisions of Sec. 217.33.
    (d) The following amendments do not constitute a new rated order: a 
change in shipping destination; a reduction in the total amount of the 
order; an increase in the total amount of the order which has negligible 
impact upon deliveries; a minor variation in size or design; or a change 
which is agreed upon between the supplier and the customer.
    (e) If a person no longer needs items or services to fill a rated 
order, any rated orders placed with suppliers for the items or services, 
or the priority rating on those orders, must be canceled.
    (f) When a priority rating is added to an unrated order, or is 
changed or canceled, all suppliers must be promptly notified in writing.



Sec. 217.37  Use of rated orders.

    (a) A person must use rated orders to obtain:
    (1) Items which will be physically incorporated into other items to 
fill rated orders, including that portion of such items normally 
consumed or converted into scrap or by-products in the course of 
processing;
    (2) Containers or other packaging materials required to make 
delivery of the finished items against rated orders;
    (3) Services, other than contracts of employment, needed to fill 
rated orders; and
    (4) MRO needed to produce the finished items to fill rated orders.
    (b) A person may use a rated order to replace inventoried items 
(including finished items) if such items were used to fill rated orders, 
as follows:
    (1) The order must be placed within 90 days of the date of use of 
the inventory.
    (2) A DO rating and the program identification symbol indicated on 
the customer's rated order must be used on the order. A DX rating may 
not be used even if the inventory was used to fill a DX-rated order.
    (3) If the priority ratings on rated orders from one customer or 
several customers contain different program identification symbols, the 
rated orders may be combined. In this case, the program identification 
symbol ``H1'' must be used (i.e., DO-H1).
    (c) A person may combine DX- and DO-rated orders from one customer 
or several customers if the items or services covered by each level of 
priority are identified separately and clearly. If different program 
identification symbols are indicated on those rated orders of equal 
priority, the person must use the program identification symbol ``H1'' 
(i.e., DO-H1 or DX-H1).
    (d) Combining rated and unrated orders.
    (1) A person may combine rated and unrated order quantities on one 
purchase order provided that:
    (i) The rated quantities are separately and clearly identified; and
    (ii) The four elements of a rated order, as required by Sec. 
217.32, are included on the order with the statement required in Sec. 
217.32(d) modified to read in substance:
    This purchase order contains rated order quantities certified for 
national defense use, and you are required to follow all applicable 
provisions of the Energy Priorities and Allocations System regulations 
at 10 CFR part 217 only as it pertains to the rated quantities.
    (2) A supplier must accept or reject the rated portion of the 
purchase order as provided in Sec. 217.33 and give preferential 
treatment only to the rated quantities as required by this part. This 
part may not be used to require preferential treatment for the unrated 
portion of the order.
    (3) Any supplier who believes that rated and unrated orders are 
being combined in a manner contrary to the intent of this part or in a 
fashion that

[[Page 79]]

causes undue or exceptional hardship may submit a request for adjustment 
or exception under Sec. 217.80.
    (e) A person may place a rated order for the minimum commercially 
procurable quantity even if the quantity needed to fill a rated order is 
less than that minimum. However, a person must combine rated orders as 
provided in paragraph (c) of this section, if possible, to obtain 
minimum procurable quantities.
    (f) A person is not required to place a priority rating on an order 
for less than $50,000, or one-half of the Simplified Acquisition 
Threshold (as established in the Federal Acquisition Regulation (FAR) 
(see FAR section 2.101) or in other authorized acquisition regulatory or 
management systems) whichever amount is greater, provided that delivery 
can be obtained in a timely fashion without the use of the priority 
rating.



Sec. 217.38  Limitations on placing rated orders.

    (a) General limitations.
    (1) A person may not place a DO- or DX-rated order unless entitled 
to do so under this part.
    (2) Rated orders may not be used to obtain:
    (i) Delivery on a date earlier than needed;
    (ii) A greater quantity of the item or services than needed, except 
to obtain a minimum procurable quantity. Separate rated orders may not 
be placed solely for the purpose of obtaining minimum procurable 
quantities on each order;
    (iii) Items or services in advance of the receipt of a rated order, 
except as specifically authorized by the Department of Energy (see Sec. 
217.41(c) for information on obtaining authorization for a priority 
rating in advance of a rated order);
    (iv) Items that are not needed to fill a rated order, except as 
specifically authorized by the Department of Energy, or as otherwise 
permitted by this part; or
    (v) Any of the following items unless specific priority rating 
authority has been obtained from the Department of Energy, a Delegate 
Agency, or the Department of Commerce, as appropriate:
    (A) Items for plant improvement, expansion, or construction, unless 
they will be physically incorporated into a construction project covered 
by a rated order; and
    (B) Production or construction equipment or items to be used for the 
manufacture of production equipment. [For information on requesting 
priority rating authority, see Sec. 217.21.]
    (vi) Any items related to the development of chemical or biological 
warfare capabilities or the production of chemical or biological 
weapons, unless such development or production has been authorized by 
the President or the Secretary of Defense.
    (b) Jurisdictional limitations.
    (1) Unless authorized by the resource agency with jurisdiction, the 
provisions of this part are not applicable to the following resources:
    (i) Food resources, food resource facilities, and the domestic 
distribution of farm equipment and commercial fertilizer (Resource 
agency with jurisdiction--Department of Agriculture);
    (ii) Health resources (Resource agency with jurisdiction--Department 
of Health and Human Services);
    (iii) All forms of civil transportation (Resource agency with 
jurisdiction--Department of Transportation);
    (iv) Water resources (Resource agency with jurisdiction--Department 
of Defense/U.S. Army Corps of Engineers); and
    (v) Communications services (Resource agency with jurisdiction--
National Communications System under E. O. 12472 of April 3, 1984).



                 Subpart D_Special Priorities Assistance



Sec. 217.40  General provisions.

    (a) The EPAS is designed to be largely self-executing. However, from 
time-to-time production or delivery problems will arise. In this event, 
a person should immediately contact the Office of Infrastructure 
Security and Energy Restoration, for guidance or assistance (Contact the 
Senior Policy Advisor for the Office of Electricity Delivery and Energy 
Reliability, as listed in Sec. 217.93). If the problem(s) cannot 
otherwise be resolved, special priorities assistance should be sought 
from the Department

[[Page 80]]

of Energy through the Office of Infrastructure Security and Energy 
Restoration (Contact the Senior Policy Advisor for the Office of 
Electricity Delivery and Energy Reliability, as listed in Sec. 217.93). 
If the Department of Energy is unable to resolve the problem or to 
authorize the use of a priority rating and believes additional 
assistance is warranted, the Department of Energy may forward the 
request to another agency with resource jurisdiction, as appropriate, 
for action. Special priorities assistance is provided to alleviate 
problems that do arise.
    (b) Special priorities assistance is available for any reason 
consistent with this part. Generally, special priorities assistance is 
provided to expedite deliveries, resolve delivery conflicts, place rated 
orders, locate suppliers, or to verify information supplied by customers 
and vendors. Special priorities assistance may also be used to request 
rating authority for items that are not normally eligible for priority 
treatment.
    (c) A request for special priorities assistance or priority rating 
authority must be submitted on Form DOE F 544 (05-11) (OMB control 
number 1910-5159) to the Senior Policy Advisor for the Office of 
Electricity Delivery and Energy Reliability, as listed in Sec. 217.93. 
Form DOE F 544 (05-11) may be obtained from the Department of Energy or 
a Delegate Agency. A sample Form DOE F 544 (05-11) is attached at 
appendix I to this part.



Sec. 217.41  Requests for priority rating authority.

    (a) If a rated order is likely to be delayed because a person is 
unable to obtain items or services not normally rated under this part, 
the person may request the authority to use a priority rating in 
ordering the needed items or services.
    (b) Rating authority for production or construction equipment.
    (1) A request for priority rating authority for production or 
construction equipment must be submitted to the U.S. Department of 
Commerce on Form BIS-999.
    (2) When the use of a priority rating is authorized for the 
procurement of production or construction equipment, a rated order may 
be used either to purchase or to lease such equipment. However, in the 
latter case, the equipment may be leased only from a person engaged in 
the business of leasing such equipment or from a person willing to lease 
rather than sell.
    (c) Rating authority in advance of a rated prime contract. (1) In 
certain cases and upon specific request, the Department of Energy, in 
order to promote the national defense, may authorize or request the 
Department of Commerce to authorize, as appropriate, a person to place a 
priority rating on an order to a supplier in advance of the issuance of 
a rated prime contract. In these instances, the person requesting 
advance rating authority must obtain sponsorship of the request from the 
Department of Energy or the appropriate Delegate Agency. The person 
shall also assume any business risk associated with the placing of rated 
orders in the event the rated prime contract is not issued.
    (2) The person must state the following in the request:
    It is understood that the authorization of a priority rating in 
advance of our receiving a rated prime contract from the Department of 
Energy and our use of that priority rating with our suppliers in no way 
commits the Department of Energy, the Department of Commerce, or any 
other government agency to enter into a contract or order or to expend 
funds. Further, we understand that the Federal Government shall not be 
liable for any cancellation charges, termination costs, or other damages 
that may accrue if a rated prime contract is not eventually placed and, 
as a result, we must subsequently cancel orders placed with the use of 
the priority rating authorized as a result of this request.
    (3) In reviewing requests for rating authority in advance of a rated 
prime contract, the Department of Energy or the Department of Commerce, 
as appropriate, will consider, among other things, the following 
criteria:
    (i) The probability that the prime contract will be awarded;
    (ii) The impact of the resulting rated orders on suppliers and on 
other authorized programs;

[[Page 81]]

    (iii) Whether the contractor is the sole source;
    (iv) Whether the item being produced has a long lead time;
    (v) The time period for which the rating is being requested.
    (4) The Department of Energy or the Department of Commerce, as 
appropriate, may require periodic reports on the use of the rating 
authority granted under paragraph (c) of this section.
    (5) If a rated prime contract is not issued, the person shall 
promptly notify all suppliers who have received rated orders pursuant to 
the advanced rating authority that the priority rating on those orders 
is cancelled.



Sec. 217.42  Examples of assistance.

    (a) While special priorities assistance may be provided for any 
reason in support of this part, it is usually provided in situations 
where:
    (1) A person is experiencing difficulty in obtaining delivery 
against a rated order by the required delivery date; or
    (2) A person cannot locate a supplier for an item or service needed 
to fill a rated order.
    (b) Other examples of special priorities assistance include:
    (1) Ensuring that rated orders receive preferential treatment by 
suppliers;
    (2) Resolving production or delivery conflicts between various rated 
orders;
    (3) Assisting in placing rated orders with suppliers;
    (4) Verifying the urgency of rated orders; and
    (5) Determining the validity of rated orders.



Sec. 217.43  Criteria for assistance.

    Requests for special priorities assistance should be timely, i.e., 
the request has been submitted promptly and enough time exists for the 
Department of Energy, the Delegate Agency, or the Department of Commerce 
for industrial resources to effect a meaningful resolution to the 
problem, and must establish that:
    (a) There is an urgent need for the item; and
    (b) The applicant has made a reasonable effort to resolve the 
problem.



Sec. 217.44  Instances where assistance may not be provided.

    Special priorities assistance is provided at the discretion of the 
Department of Energy, the Delegate Agencies, or the Department of 
Commerce when it is determined that such assistance is warranted to meet 
the objectives of this part. Examples where assistance may not be 
provided include situations when a person is attempting to:
    (a) Secure a price advantage;
    (b) Obtain delivery prior to the time required to fill a rated 
order;
    (c) Gain competitive advantage;
    (d) Disrupt an industry apportionment program in a manner designed 
to provide a person with an unwarranted share of scarce items; or
    (e) Overcome a supplier's regularly established terms of sale or 
conditions of doing business.



                      Subpart E_Allocation Actions



Sec. 217.50  Policy.

    (a) It is the policy of the Federal Government that the allocations 
authority under title I of the Defense Production Act may:
    (1) Only be used when there is insufficient supply of a material, 
service, or facility to satisfy national defense supply requirements 
through the use of the priorities authority or when the use of the 
priorities authority would cause a severe and prolonged disruption in 
the supply of materials, services, or facilities available to support 
normal U.S. economic activities; and
    (2) Not be used to ration materials or services at the retail level.
    (b) Allocation orders, when used, will be distributed equitably 
among the suppliers of the materials, services, or facilities being 
allocated and not require any person to relinquish a disproportionate 
share of the civilian market.



Sec. 217.51  General procedures.

    When the Department of Energy plans to execute its allocations 
authority to address a supply problem within its resource jurisdiction, 
the Department shall develop a plan that includes the following 
information:
    (a) A copy of the written determination made, in accordance with 
section

[[Page 82]]

202 of E.O. 12919, that the program or programs that would be supported 
by the allocation action are necessary or appropriate to promote the 
national defense;
    (b) A detailed description of the situation to include any unusual 
events or circumstances that have created the requirement for an 
allocation action;
    (c) A statement of the specific objective(s) of the allocation 
action;
    (d) A list of the materials, services, or facilities to be 
allocated;
    (e) A list of the sources of the materials, services, or facilities 
that will be subject to the allocation action;
    (f) A detailed description of the provisions that will be included 
in the allocation orders, including the type(s) of allocation orders, 
the percentages or quantity of capacity or output to be allocated for 
each purpose, and the duration of the allocation action (i.e., 
anticipated start and end dates);
    (g) An evaluation of the impact of the proposed allocation action on 
the civilian market; and
    (h) Proposed actions, if any, to mitigate disruptions to civilian 
market operations.



Sec. 217.52  Controlling the general distribution of a material
in the civilian market.

    No allocation action by the Department of Energy may be used to 
control the general distribution of a material in the civilian market, 
unless the Secretary of the Department of Energy has:
    (a) Made a written finding that:
    (1) Such material is a scarce and critical material essential to the 
national defense, and
    (2) The requirements of the national defense for such material 
cannot otherwise be met without creating a significant dislocation of 
the normal distribution of such material in the civilian market to such 
a degree as to create appreciable hardship;
    (b) Submitted the finding for the President's approval through the 
Assistant to the President for National Security Affairs; and
    (c) The President has approved the finding.



Sec. 217.53  Types of allocation orders.

    There are three types of allocation orders available for 
communicating allocation actions. These are:
    (a) Set-aside: an official action that requires a person to reserve 
materials, services, or facilities capacity in anticipation of the 
receipt of rated orders;
    (b) Directive: an official action that requires a person to take or 
refrain from taking certain actions in accordance with its provisions. 
For example, a directive can require a person to: stop or reduce 
production of an item; prohibit the use of selected materials, services, 
or facilities; or divert the use of materials, services, or facilities 
from one purpose to another; and
    (c) Allotment: an official action that specifies the maximum 
quantity of a material, service, or facility authorized for a specific 
use.



Sec. 217.54  Elements of an allocation order.

    Each allocation order must include:
    (a) A detailed description of the required allocation action(s);
    (b) Specific start and end calendar dates for each required 
allocation action;
    (c) The written signature on a manually placed order, or the digital 
signature or name on an electronically placed order, of the Secretary of 
Energy. The signature or use of the name certifies that the order is 
authorized under this part and that the requirements of this part are 
being followed;
    (d) A statement that reads in substance: ``This is an allocation 
order certified for national defense use. [Insert the legal name of the 
person receiving the order] is required to comply with this order, in 
accordance with the provisions of the Energy Priorities and Allocations 
System regulation (10 CFR part 217), which is part of the Federal 
Priorities and Allocations System''; and
    (e) A current copy of the Energy Priorities and Allocations System 
regulation (10 CFR part 217).



Sec. 217.55  Mandatory acceptance of an allocation order.

    (a) Except as otherwise specified in this section, a person shall 
accept and

[[Page 83]]

comply with every allocation order received.
    (b) A person shall not discriminate against an allocation order in 
any manner such as by charging higher prices for materials, services, or 
facilities covered by the order or by imposing terms and conditions for 
contracts and orders involving allocated materials, services, or 
facilities that differ from the person's terms and conditions for 
contracts and orders for the materials, services, or facilities prior to 
receiving the allocation order.
    (c) If a person is unable to comply fully with the required 
action(s) specified in an allocation order, the person must notify the 
Department of Energy immediately, explain the extent to which compliance 
is possible, and give the reasons why full compliance is not possible. 
If notification is given verbally, written or electronic confirmation 
must be provided within five (5) working days. Such notification does 
not release the person from complying with the order to the fullest 
extent possible, until the person is notified by the Department of 
Energy that the order has been changed or cancelled.



Sec. 217.56  Changes or cancellations of an allocation order.

    An allocation order may be changed or canceled by an official action 
of the Department of Energy.



                       Subpart F_Official Actions



Sec. 217.60  General provisions.

    (a) A Rating Authorization is an official action granting specific 
priority rating authority that:
    (1) Permits a person to place a priority rating on an order for an 
item or service not normally ratable under this part; or
    (2) Authorizes a person to modify a priority rating on a specific 
order or series of contracts or orders.
    (b) To request priority rating authority, see Sec. 217.41.



Sec. 217.62  Directives.

    (a) A Directive is an official action that requires a person to take

    (b) A person must comply with each Directive issued. However, a 
person may not use or extend a Directive to obtain any items from a 
supplier, unless expressly authorized to do so in the Directive.
    (c) A Priorities Directive takes precedence over all DX-rated 
orders, DO-rated orders, and unrated orders previously or subsequently 
received, unless a contrary instruction appears in the Directive.
    (d) An Allocations Directive takes precedence over all Priorities 
Directives, DX-rated orders, DO-rated orders, and unrated orders 
previously or subsequently received, unless a contrary instruction 
appears in the Directive.



Sec. 217.63  Letters and Memoranda of Understanding.

    (a) A Letter or Memorandum of Understanding is an official action 
that may be issued in resolving special priorities assistance cases to 
reflect an agreement reached by all parties (the Department of Energy, 
the Department of Commerce (if applicable), a Delegate Agency (if 
applicable), the supplier, and the customer).
    (b) A Letter or Memorandum of Understanding is not used to alter 
scheduling between rated orders, to authorize the use of priority 
ratings, to impose restrictions under this part. Rather, Letters or 
Memoranda of Understanding are used to confirm production or shipping 
schedules that do not require modifications to other rated orders.



                          Subpart G_Compliance



Sec. 217.70  General provisions.

    (a) The Department of Energy may take specific official actions for 
any reason necessary or appropriate to the enforcement or the

    (2) Have ascertained that the information sought or other adequate 
and authoritative data are not available from any Federal or other 
responsible agency.
    (c) In administering this part, the Department of Energy may issue 
the following documents that constitute official actions:
    (1) Administrative Subpoenas. An Administrative Subpoena requires a 
person to appear as a witness before an official designated by the 
Department of Energy to testify under oath on matters of which that 
person has knowledge relating to the enforcement or the administration 
of the Defense Production Act and other applicable statutes, this part, 
or official actions. An Administrative Subpoena may also require the 
production of books, papers, records, documents and physical objects or 
property.
    (2) Demands for Information. A Demand for Information requires a 
person to furnish to a duly authorized representative of the Department 
of Energy any information necessary or appropriate to the enforcement or

Energy to interview the person's employees or agents, to inspect books, 
records, documents, other writings, and information, including 
electronically-stored information, in the person's possession or control 
at the place where that person usually keeps them or otherwise, and to 
inspect a person's property when such interviews and inspections are 
necessary or appropriate to the enforcement or the administration of the 
Defense Production Act and related statutes, this part, or official 
actions.
    (d) The production of books, records, documents, other writings, and 
information will not be required at any place other than where they are 
usually kept if, prior to the return date specified in the 
Administrative Subpoena or Demand for Information, a duly authorized 
official of the Department of Energy is furnished with copies of such 
material that are certified under oath to be true copies. As an 
alternative, a person may enter into a stipulation with a duly 
authorized official of Department of Energy as to the content of the 
material.
    (e) An Administrative Subpoena, Demand for Information, or 
Inspection Authorization, shall include the name, title, or official 
position of the person to be served, the evidence sought to be adduced, 
and its general relevance to the scope and purpose of the audit, 
investigation, or other inquiry. If employees or agents are to be 
interviewed; if books, records, documents, other writings, or

Administrative Subpoena, Demand

[[Page 85]]

for Information, or Inspection Authorization will describe them with 
particularity.
    (f) Service of documents shall be made in the following manner:
    (1) Service of a Demand for Information or Inspection Authorization 
shall be made personally, or by Certified Mail-Return Receipt Requested 
at the person's last known address. Service of an Administrative 
Subpoena shall be made personally. Personal service may also be made by 
leaving a copy of the document with someone at least 18 years old at the 
person's last known dwelling or place of business.
    (2) Service upon other than an individual may be made by serving a 
partner, corporate officer, or a managing or general agent authorized by 
appointment or by law to accept service of process. If an agent is 
served, a copy of the document shall be mailed to the person named in 
the document.
    (3) Any individual 18 years of age or over may serve an 
Administrative Subpoena, Demand for Information, or Inspection 
Authorization. When personal service is made, the individual making the 
service shall prepare an affidavit as to the manner in which service was 
made and the identity of the person served, and return the affidavit, 
and in the case of subpoenas, the original document, to the issuing 
officer. In case of failure to make service, the reasons for the failure 
shall be stated on the original document.



Sec. 217.72  Compulsory process.

reason to believe that the item will be accepted, redelivered, held, or 
used in violation of the Defense Production Act and other applicable 
statutes, this part, or an official action. In such instances, the 
person must immediately notify the Department of Energy that, in 
accordance with this provision, delivery has not been made.



Sec. 217.75  Compliance conflicts.

    If compliance with any provision of the Defense Production Act and 
other applicable statutes, this part, or an official action would 
prevent a person from filling a rated order or from complying with 
another provision of the Defense Production Act and other applicable 
statutes, this part, or an official action, the person must immediately 
notify the Department of Energy for resolution of the conflict.

investigation of any statement in an application and utilize in its 
evaluation any relevant facts obtained by such investigation. The DOE 
may solicit and accept submissions from third parties relevant to any 
application for review provided that the applicant is afforded an 
opportunity to respond to all third party submissions. In evaluating an 
application for review, the DOE may convene a conference, on its own 
initiative, if, in its discretion, it considers that a conference will 
advance its evaluation of the application.
    (ii) If the DOE determines that there is insufficient information 
upon which to base a decision and if upon request the necessary 
additional information is not submitted, the DOE may dismiss the 
application without prejudice. If the failure to supply additional 
information is repeated or willful, the DOE may dismiss the application 
with prejudice. If the applicant fails to provide the notice required by

without prejudice.
    (iii) An order dismissing an application for any of the reasons 
specified in paragraph (g)(1)(ii) of this section shall contain a

within 5 days of its service upon the applicant, unless within such 5-
day period the applicant files an amendment correcting the deficiencies 
identified in the order. Within 5 days of the filing of such amendment, 
the DOE shall notify the applicant whether the amendment corrects the 
specified deficiencies. If the amendment does not correct the 
deficiencies specified in the order, the order shall become a final 
order of the DOE of which the applicant may seek judicial review.
    (2) An application for review of an order shall be processed only if 
the applicant demonstrates that--
    (i) There is probable cause to believe that the supply order is 
erroneous, inequitable, or unduly burdensome; or
    (ii) There has been discovered a law, regulation, interpretation, 
ruling, order or decision that was in effect at the time of the 
application which, if it had been made known to the DOE, would have been 
relevant to the supply order and would have substantially altered the 
supply order; or
    (iii) There has been a substantial change in the facts or 
circumstances affecting the applicant, which change has occurred during 
the interval between issuance of the supply order and the date of the 
application and was caused by forces or circumstances beyond the control 
of the applicant.
    (h) Decision. (1) Upon consideration of the application and other 
relevant information received or obtained during the proceeding, the DOE 
shall issue an order granting or denying the modification or rescission 
of the supply order requested in the application for review.
    (2) The DOE shall process applications for review as expeditiously 
as possible. When administratively feasible, the DOE shall issue an 
order granting or denying the application within 20 business days after 
receipt of the application.
    (3) The order shall include a written statement setting forth the 
relevant facts and the legal basis of the order. The order shall state

serious and irreparable injury unless immediate stay relief is granted 
pending determination of an application for review pursuant to this 
subpart. An application for a stay shall be labeled as

[[Page 94]]

such on the application and on the outside of the envelope in which the 
application is transmitted, and shall be in writing and signed by the 
firm filing the application. It shall include a description of the 
proceeding incident to which the stay is being sought and of the facts 
and circumstances which support the applicant's claim that it will incur 
irreparable injury unless immediate stay relief is granted. The 
applicant shall comply with the general filing requirements stated in 10 
CFR 205.9 in addition to the requirements stated in this section. The 
DOE on its own initiative may also issue an order granting a stay upon a 
finding that a firm will incur irreparable injury if such an order is 
not granted.
    (b) An order granting a stay shall expire by its terms within such 
time after issuance, not to exceed 30 days as the DOE specifies in the 
order, except that it shall expire automatically 5 days following its 
issuance if the applicant fails within that period to file an 
application for review unless within that period the DOE for good cause 
shown, extends the time during which the applicant may file an 
application for review.
    (c) The order granting or denying a stay is not an order of the DOE 
subject to administrative review.



Sec. 218.34  Addresses.

            Subpart D_Administrative Procedures and Sanctions



Sec. 221.31  Requests by DOD.

    (a) When DOD finds that (1) a fuel supply shortage for DOD exists or 
is anticipated which would have a substantial negative impact on the 
national defense, and (2) the defense activity for which fuel is 
required cannot be postponed until after the fuel supply shortage is 
likely to terminate, DOD may submit a written request to ERA for the 
issuance to it of a priority rating for the supply of crude oil and 
petroleum products.
    (b) Not later than the transmittal date of its request to ERA, DOD 
shall notify the Federal Emergency Management Agency that it has 
requested a priority rating from ERA.
    (c) Requests from DOD shall set forth the following:
    (1) The quantity and quality of crude oil or petroleum products 
determined by DOD to be required to meet national defense requirements;
    (2) The required delivery dates;
    (3) The defense-related activity and the supply location for which 
the crude oil or petroleum product is to be delivered;

[[Page 97]]

    (4) The current or most recent suppliers of the crude oil or 
petroleum product and the reasons, if known, why the suppliers will not 
supply the requested crude oil or petroleum product;
    (5) The degree to which it is feasible for DOD to use an alternate 
product in lieu of that requested and, if such an alternative product 
can be used, the efforts which have been made to obtain the alternate 
product;
    (6) The period during which the shortage of crude oil or petroleum 
products is expected to exist;
    (7) The proposed supply source for the additional crude oil or 
petroleum products required, which shall, if practicable, be the 
historical supplier of such crude oil or product to DOD; and
    (8) Certification that DOD has made each of the findings required by 
paragraph (a) of this section.



Sec. 221.32  Evaluation of DOD request.

    (a) Upon receipt of a request from DOD for a priority rating as 
provided in Sec. 221.31, it shall be reviewed promptly by ERA. The ERA 
will assess the request in terms of:
    (1) The information provided under Sec. 221.31;
    (2) Whether DOD's national defense needs for crude oil or petroleum 
products can reasonably be satisfied without exercising the authority 
specified in this part;
    (3) The capability of the proposed supplier to supply the crude oil 
or petroleum product in the amounts required;
    (4) The known capabilities of alternative suppliers;
    (5) The feasibility to DOD of converting to and using a product 
other than that requested; and
    (6) Any other relevant information.
    (b) The ERA promptly shall notify the proposed supplier of DOD's 
request for a priority rating specified under this part. The proposed 
supplier shall have a period specified in the notice, not to exceed 
fifteen (15) days from the date it is notified of DOD's request, to show 
cause in writing why it cannot supply the requested quantity and quality 
of crude oil or petroleum products. ERA shall consider this information 
in determining whether to issue the priority rating.
    (c) If acceptance by a supplier of a rated order would create a 
conflict with another rated order of the supplier, it shall include all 
pertinent information regarding such conflict in its response to the 
show cause order provided for in subsection (b), and ERA, in 
consultation with DOD and the Federal Emergency Management Agency shall 
determine the priorities for meeting all such requirements.
    (d) ERA may waive some or all of the requirements of Sec. 221.31 or 
this section where the Secretary of Defense or his designee certifies, 
and has so notified the Federal Emergency Management Agency, that a fuel 
shortage for DOD exists or is imminent and that compliance with such 
requirements would have a substantial negative impact on the national 
defense.



Sec. 221.33  Order.

    (a) Issuance. If ERA determines that issuance of a priority rating 
for a crude oil or refined petroleum product is necessary to provide the 
crude oil or petroleum products needed to meet the national defense 
requirement established by DOD, it shall issue such a rating to DOD for 
delivery of specified qualities and quantities of the crude oil or 
refined petroleum products on or during specified delivery dates or 
periods. In accordance with the terms of the order, DOD may then place 
such priority rating on a supply order.
    (b) Compliance. Each person who receives a priority-rated supply 
order pursuant to this part shall supply the specified crude oil or 
petroleum products to DOD in accordance with the terms of that order.
    (c) ERA directives. Notwithstanding any other provisions of this 
part, where necessary or appropriate to promote the national defense ERA 
is authorized to issue a directive to a supplier of crude oil or 
petroleum product requiring delivery of specified qualities and 
quantities of such crude oil or petroleum products to DOD at or during 
specified delivery dates or periods.
    (d) Use of ratings by suppliers. No supplier who receives a 
priority-rated supply order or directive issued under the authority of 
this section may use such priority order or directive in order to

[[Page 98]]

obtain materials necessary to meet its supply obligations thereunder.



Sec. 221.34  Effect of order.

    Defense against claims for damages. No person shall be liable for 
damages or penalties for any act or failure to act resulting directly or 
indirectly from compliance with any ERA authorized priority-rated supply 
order or ERA directive issued pursuant to this part, notwithstanding 
that such priority-rated supply order or directive thereafter be 
declared by judicial or other competent authority to be invalid.



Sec. 221.35  Contractual requirements.

    (a) No supplier may discriminate against an order or contract on 
which a priority rating has been placed under this part by charging 
higher prices, by imposing terms and conditions for such orders or 
contracts different from other generally comparable orders or contracts, 
or by any other means.
    (b) Contracts with priority ratings shall be subject to all 
applicable laws and regulations which govern the making of such 
contracts, including those specified in 10 CFR 211.26(e).



Sec. 221.36  Records and reports.

    (a) Each person receiving an order or directive under this part 
shall keep for at least two years from the date of full compliance with 
such order or directive accurate and complete records of crude oil and 
petroleum product deliveries made in accordance with such order or 
directive.

    Source: 71 FR 20805, Apr. 21, 2006, unless otherwise noted.



Sec. 300.1  General.

    (a) Purpose. The General Guidelines in this part and the Technical 
Guidelines incorporated by reference in Sec. 300.13 govern the 
Voluntary Reporting of Greenhouse Gases Program authorized by section 
1605(b) of the Energy Policy Act of 1992 (42 U.S.C. 13385(b)). The 
purpose of the guidelines is to establish the procedures and 
requirements for filing voluntary reports, and to encourage 
corporations, government agencies, non-profit organizations, households 
and other private and public entities to submit annual reports of their 
greenhouse gas emissions, emission reductions, and sequestration 
activities that are complete, reliable and consistent. Over time, it is 
anticipated that these reports will provide a reliable record of the 
contributions reporting entities have made toward reducing their 
greenhouse gas emissions.
    (b) Reporting under the program. (1) Each reporting entity, whether 
or not it intends to register emissions as described in paragraph (c) of 
this section, must:
    (i) File an entity statement that meets the appropriate requirements 
in Sec. 300.5(d) through (f) of this part;
    (ii) Use appropriate emission inventory and emission reduction 
calculation methods specified in the Technical Guidelines (incorporated 
by reference, see Sec. 300.13), and calculate and report the weighted 
average quality rating of any emission inventories it reports;
    (iii) Comply with the record keeping requirements in Sec. 300.9 of 
this part; and
    (iv) Comply with the certification requirements in Sec. 300.10 of 
this part;
    (2) Each reporting entity, whether or not it intends to register 
emissions as described in paragraph (c) of this section, may report 
offset reductions achieved by other entities outside their boundaries as 
long as such reductions are reported separately and calculated in 
accordance with methods specified in the Technical Guidelines. The 
third-party entity that achieved these reductions must agree to their 
being reported as offset reductions, and must also meet all of the 
requirements of reporting that would apply if the third-party entity 
reported directly under the 1605(b) program.
    (3) An entity that intends to register emissions and emission 
reductions must meet the additional requirements referenced in paragraph 
(c) of this section.
    (4) An entity that does not intend to register emissions and 
emission reductions may choose to report its emissions and/or emission 
reductions on an entity-wide basis or for selected elements of the 
entity, selected gases or selected sources.
    (5) An entity that does not intend to register emissions may report 
emission inventories for any year back to 1990 and may report emission 
reductions for any year back to 1991, relative to a base period of one 
to four years, ending no earlier than 1990.
    (c) Registration requirements. Entities that seek to register 
reductions must meet the additional requirements in this paragraph; 
although these requirements differ depending on whether the entity is a 
large or small emitter.
    (1) To be eligible for registration, a reduction must have been 
achieved after 2002, unless the entity has committed under the Climate 
Leaders or

[[Page 100]]

Climate VISION programs to reduce its entity-wide emissions relative to 
a base period that ends earlier 2002, but no earlier than 2000.
    (2) A large emitter must submit an entity-wide emission inventory 
that meets or exceeds the minimum quality requirements specified in 
Sec. 300.6(b) and the Technical Guidelines (incorporated by reference, 
see Sec. 300.13). Registered reductions of a large emitter must be 
based on an entity-wide assessment of net emission reductions, 
determined in accordance with Sec. 300.8 and the Technical Guidelines.
    (3) A small emitter must also submit an emission inventory that 
meets minimum quality requirements specified in Sec. 300.6(b) and the 
Technical Guidelines (incorporated by reference, see Sec. 300.13) and 
base its registered reductions on an assessment of annual changes in net 
emissions. A small emitter, however, may restrict its inventory and 
assessment to a single type of activity, such as forest management, 
building operations or agricultural tillage.
    (4) Reporting entities may, under certain conditions, register 
reductions achieved by other entities:
    (i) Reporting entities that have met the requirements for 
registering their own reductions may also register offset reductions 
achieved by other entities if:
    (A) They have an agreement with the third-party entities to do so 
and these third-party entities have met all of the requirements for 
registration; or
    (B) They were the result of qualified demand management or other 
programs and are calculated in accordance with the action-specific 
method identified in Sec. 300.8(h)(5).
    (ii) Small emitters that serve as an aggregator may register offset 
reductions achieved by non-reporting entities without reporting on their 
own emissions, as long as they have an agreement with the third-party 
entities to do so and these third-party entities have met all of the 
requirements for registration.
    (d) Forms. Annual reports of greenhouse gas emissions, emission 
reductions, and sequestration must be made on forms or software made 
available by the Energy Information Administration of the Department of 
Energy (EIA).
    (e) Status of reports under previous guidelines. EIA continues to 
maintain in its Voluntary Reporting of Greenhouse Gases database all 
reports received pursuant to DOE's October 1994 guidelines. Those 
guidelines are available from EIA at http://www.eia.doe.gov/oiaf/1605/
guidelns.html.
    (f) Periodic review and updating of General and Technical 
Guidelines. DOE intends periodically to review the General Guidelines 
and the Technical Guidelines (incorporated by reference, see Sec. 
300.13) to determine whether any changes are warranted; DOE anticipates 
these reviews will occur approximately once every three years. These 
reviews will consider any new developments in climate science or policy, 
the participation rates of large and small emitters in the 1605(b) 
program, the general quality of the data submitted by different 
participants, and any changes to other emissions reporting protocols. 
Possible changes may include, but are not limited to:
    (1) The addition of greenhouse gases that have been demonstrated to 
have significant, quantifiable climate forcing effects when released to 
the atmosphere in significant quantities;
    (2) Changes to the minimum, quantity-weighted quality rating for 
emission inventories;
    (3) Updates to emission inventory methods, emission factors and 
other provisions that are contained in industry protocols or standards. 
The review may also consider updates to any government-developed and 
consensus-based emission factors for which automatic updating is not 
provided in the Technical Guidelines;
    (4) Modifications to the benchmarks or emission conversion factors 
used to calculate avoided and indirect emissions; and
    (5) Changes in the minimum requirements for registered emission 
reductions.



Sec. 300.2  Definitions.

    This section provides definitions for commonly used terms in this 
part.
    Activity of a small emitter means, with respect to a small emitter, 
any single category of anthropogenic production,

[[Page 101]]

consumption or other action that releases emissions or results in 
sequestration, the annual changes of which can be assessed generally by 
using a single calculation method.
    Aggregator means an entity that reports to the 1605(b) program on 
behalf of non-reporting entities. An aggregator may be a large or small 
emitter, such as a trade association, non-profit organization or public 
agency.
    Anthropogenic means greenhouse gas emissions and removals that are a 
direct result of human activities or are the result of natural processes 
that have been affected by human activities.
    Avoided emissions means the greenhouse gas emission reductions that 
occur outside the organizational boundary of the reporting entity as a 
direct consequence of changes in the entity's activity, including but 
not necessarily limited to the emission reductions associated with 
increases in the generation and sale of electricity, steam, hot water or 
chilled water produced from energy sources that emit fewer greenhouse 
gases per unit than other competing sources of these forms of 
distributed energy.
    Base period means a period of 1-4 years used to derive the average 
annual base emissions, emissions intensity or other values from which 
emission reductions are calculated.
    Base value means the value from which emission reductions are 
calculated for an entity or subentity. The value may be annual 
emissions, emissions intensity, kilowatt-hours generated, or other value 
specified in the 1605(b) guidelines. It is usually derived from actual 
emissions and/or activity data derived from the base period.
    Biogenic emissions mean emissions that are naturally occurring and 
are not significantly affected by human actions or activity.
    Boundary means the actual or virtual line that encompasses all the 
emissions and carbon stocks that are to be quantified and reported in an 
entity's greenhouse gas inventory, including de minimis emissions. 
Entities may use financial control or another classification method 
based on ownership or control as the means of determining which sources 
or carbon stocks fall within this organizational boundary.
    Carbon dioxide equivalent means the amount of carbon dioxide by 
weight emitted into the atmosphere that would produce the same estimated 
radiative forcing as a given weight of another radiatively active gas. 
Carbon dioxide equivalents are computed by multiplying the weight of the 
gas being measured by its estimated global warming potential.
    Carbon stocks mean the quantity of carbon stored in biological and 
physical systems including: trees, products of harvested trees, 
agricultural crops, plants, wood and paper products and other 
terrestrial biosphere sinks, soils, oceans, and sedimentary and 
geological sinks.
    Climate Leaders means the EPA sponsored industry-government 
partnership that works with individual companies to develop long-term 
comprehensive climate change strategies. Certain Climate Leaders 
Partners have, working with EPA, set a corporate-wide greenhouse gas 
reduction goal and have inventoried their emissions to measure progress 
towards their goal.
    Climate VISION means the public-private partnership initiated 
pursuant to a Presidential directive issued in 2002 that aims to 
contribute to the President's goal of reducing greenhouse gas intensity 
through voluntary frameworks with industry. Climate VISION partners have 
signed an agreement with DOE to implement various climate-related 
actions to reduce greenhouse gas emissions.
    De minimis emissions means emissions from one or more sources and of 
one or more greenhouse gases that, in aggregate, are less than or equal 
to 3 percent of the total annual carbon dioxide (CO2) 
equivalent emissions of a reporting entity.
    Department or DOE means the U.S. Department of Energy.
    Direct emissions are emissions from sources within the 
organizational boundaries of an entity.
    Distributed energy means electrical or thermal energy generated by 
an entity that is sold or otherwise exported outside of the entity's 
boundaries for use by another entity.

[[Page 102]]

    EIA means the Energy Information Administration within the U.S. 
Department of Energy.
    Emissions means the direct release of greenhouse gases to the 
atmosphere from any anthropogenic (human induced) source and certain 
indirect emissions (releases) specified in this part.
    Emissions intensity means emissions per unit of output, where output 
is defined as the quantity of physical output, or a non-physical 
indicator of an entity's or subentity's productive activity.
    Entity means the whole or part of any business, institution, 
organization, government agency or corporation, or household that:
    (1) Is recognized under any U.S. Federal, State or local law that 
applies to it;
    (2) Is located and operates, at least in part, in the United States; 
and
    (3) The emissions of such operations are released, at least in part, 
in the United States.
    First reduction year means the first year for which an entity 
intends to register emission reductions; it is the year that immediately 
follows the start year.
    Fugitive emissions means uncontrolled releases to the atmosphere of 
greenhouse gases from the processing, transmission, and/or 
transportation of fossil fuels or other materials, such as HFC leaks 
from refrigeration, SF6 from electrical power distributors, and methane 
from solid waste landfills, among others, that are not emitted via an 
exhaust pipe(s) or stack(s).
    Greenhouse gases means the gases that may be reported to the 
Department of Energy under this program. They are:
    (1) Carbon dioxide (CO2)
    (2) Methane (CH4)
    (3) Nitrous oxide (N2O)
    (4) HydrofluorocarbonsHFC-23 [trifluoromethane-(CHF3]HFC-
32 [trifluoromethane-CH2F2], 
CH2CF3, CH3F, 
CHF2CF3, CH2FCF3, 
CH3FCF3, CHF2CH2F,

    (5) Perfluorocarbons (perfluoromethane-CF4, 
perfluoroethane-C2F6, C3F8, 
C4F10, c-C4F8, 
C5F12, C6F14)
    (6) Sulfur hexafluoride (SF6)

CCl3F], CCl2F2, CClF3, 
CCl2FCClF2, CClF2CClF2, 
ClF3CClF2,)
    (8) Other gases or particles that have been demonstrated to have 
significant, quantifiable climate forcing effects when released to the 
atmosphere in significant quantities and for which DOE has established 
or approved methods for estimating emissions and reductions. (Note: As 
provided in Sec. 300.6(i), chlorofluorcarbons and other gases with 
quantifiable climate forcing effects may be reported to the 1605(b) 
program if DOE has established an appropriate emission inventory or 
emission reduction calculation method, but reductions of these gases may 
not be registered.)
    Incidental lands are entity landholdings that are a minor component 
of an entity's operations and are not actively managed for production of 
goods and services, including:
    (1) Transmission, pipeline, or transportation right of ways that are 
not managed for timber production;
    (2) Land surrounding commercial enterprises or facilities; and
    (3) Land where carbon stock changes are determined by natural 
factors.
    Indirect emissions means greenhouse gas emissions from stationary or 
mobile sources outside the organizational boundary that occur as a 
direct consequence of an entity's activity, including but not 
necessarily limited to the emissions associated with the generation of 
electricity, steam and hot/chilled water used by the entity.
    Large emitter means an entity whose annual emissions are more than 
10,000 metric tons of CO2 equivalent, as determined in 
accordance with Sec. 300.5(c).
    Net emission reductions means the sum of all annual changes in 
emissions, eligible avoided emissions and sequestration of the 
greenhouse gases specifically identified in Sec. 300.6(i), and 
determined to be in conformance with Sec. Sec. 300.7 and 300.8 of this 
part.
    Offset means an emission reduction that is included in a 1605(b) 
report and

[[Page 103]]

meets the requirements of this part, but is achieved by an entity other 
than the reporting entity. Offset reductions must not be reported or 
registered by any other entity and must appear as a separate and 
distinct component of an entity's report. Offsets are not integrated 
into the reporting entity's emissions or net emission reductions.
    Registration means the reporting of emission reductions that the EIA 
has determined meet the qualifications for registered emission 
reductions set forth in the guidelines.
    Reporting entity means an entity that has submitted a report under 
the 1605(b) program that has been accepted by the Energy Information 
Administration.
    Reporting year means the year that is the subject of a report to 
DOE.
    Sequestration means the process by which CO2 is removed 
from the atmosphere, either through biologic processes or physical 
processes.
    Simplified Emission Inventory Tool (SEIT) is a computer-based 
method, to be developed and made readily accessible by EIA, for 
translating common physical indicators into an estimate of greenhouse 
gas emissions.
    Sink means an identifiable discrete location, set of locations, or 
area in which CO2 or some other greenhouse gas is 
sequestered.
    Small emitter means an entity whose annual emissions are less than 
or equal to 10,000 metric tons of CO2 equivalent, as 
determined in accordance with Sec. 300.5(c), and that chooses to be 
treated as a small emitter under the guidelines.
    Source means any land, facility, process, vehicle or activity that 
releases a greenhouse gas.
    Start year means the year upon which the initial entity statement is 
based and the last year of the initial base period(s).
    Subentity means a component of any entity, such as a discrete 
business line, facility, plant, vehicle fleet, or energy using system, 
which has associated with it emissions of greenhouse gases that can be 
distinguished from the emissions of all other components of the same 
entity and, when summed with the emissions of all other subentities, 
equal the entity's total emissions.
    Total emissions means the total annual contribution of the 
greenhouse gases (as defined in this section) to the atmosphere by an 
entity, including both direct and indirect entity-wide emissions.
    United States or U.S. means the 50 States, the District of Columbia, 
the Commonwealth of Puerto Rico, the Commonwealth of the Northern 
Mariana Islands, Guam, American Samoa, and any other territory of the 
United States.



Sec. 300.3  Guidance for defining and naming the reporting entity.

    (a) A reporting entity must be composed of one or more businesses, 
public or private institutions or organizations, households, or other 
entities having operations that annually release emissions, at least in 
part, in the United States. Entities may be defined by, as appropriate, 
a certificate of incorporation, corporate charter, corporate filings, 
tax identification number, or other legal basis of identification 
recognized under any Federal, State or local law or regulation. If a 
reporting entity is composed of more than one entity, all of the 
entities included must be responsible to the same management hierarchy 
and all entities that have the same management hierarchy must be 
included in the reporting entity.
    (b) All reporting entities are strongly encouraged to define 
themselves at the highest level of aggregation. To achieve this 
objective, DOE suggests the use of a corporate-level definition of the 
entity, based on filings with the Securities and Exchange Commission or 
institutional charters. While reporting at the highest level of 
aggregation is encouraged, DOE recognizes that certain businesses and 
institutions may conclude that reporting at some lower level is 
desirable. Federal agencies are encouraged to report at the agency or 
departmental level, but distinct organizational units (such as a 
Department of the Interior Fish and Wildlife Service National Wildlife 
Refuge) may report directly if authorized by their department or agency. 
Once an entity has determined the level of corporate or institutional 
management at which it will report (e.g., the holding

[[Page 104]]

company, subsidiary, regulated stationary source, state government, 
agency, refuge, etc.), the entity must include all elements of the 
organization encompassed by that management level and exclude any 
organizations that are managed separately. For example, if two 
subsidiaries of a parent company are to be covered by a single report, 
then all subsidiaries of that parent company must also be included. 
Similarly, if a company decides to report on the U.S. and Canadian 
subsidiaries of its North American operations unit, it must also report 
on any other subsidiaries of its North American unit, such as a Mexican 
subsidiary.
    (c) A name for the defined entity must be specified by all 
reporters. For entities that intend to register reductions, this should 
be the name commonly used to represent the activities being reported, as 
long as it is not also used to refer to substantial activities not 
covered by the entity's reports. While DOE believes entities should be 
given considerable flexibility in defining themselves at an appropriate 
level of aggregation, it is essential that the name assigned to an 
entity that intends to register reductions corresponds closely to the 
scope of the operations and emissions covered by its report. If, for 
example, an individual plant or operating unit is reporting as an 
entity, it should be given a name that corresponds to the specific plant 
or unit, and not to the responsible subsidiary or corporate entity. In 
order to distinguish a parent company from its subsidiaries, the name of 
the parent company generally should not be incorporated into the name of 
the reporting subsidiary, but if it is, the name of the parent company 
usually should be secondary.



Sec. 300.4  Selecting organizational boundaries.

    (a) Each reporting entity must disclose in its entity statement the 
approach used to establish its organizational boundaries, which should 
be consistent with the following guidelines:
    (1) In general, entities should use financial control as the primary 
basis for determining their organizational boundaries, with financial 
control meaning the ability to direct the financial and operating 
policies of all elements of the entity with a view to gaining economic 
or other benefits from its activities over a period of many years. This 
approach should ensure that all sources, including those controlled by 
subsidiaries, that are wholly or largely owned by the entity are covered 
by its reports. Sources that are under long-term lease of the entity 
may, depending on the provisions of such leases, also be considered to 
be under the entity's financial control. Sources that are temporarily 
leased or operated by an entity generally would not be considered to be 
under its financial control.
    (2) Entities may establish organizational boundaries using 
approaches other than financial control, such as equity share or 
operational control, but must disclose how the use of these other 
approaches results in organizational boundaries that differ from those 
resulting from using the financial control approach.
    (3) Emissions from facilities or vehicles that are partially-owned 
or leased may be included at the entity's discretion, provided that the 
entity has taken reasonable steps to assure that doing so does not 
result in the double counting of emissions, sequestration or emission 
reductions. Emissions reductions or sequestration associated with land, 
facilities or other sources not owned or leased by an entity may not be 
included in the entity's reports under the program unless the entity has 
long-term control over the emissions or sequestration of the source and 
the owner of the source has agreed that the emissions or sequestration 
may be included in the entity's report.
    (4) If the scope of a defined entity extends beyond the United 
States, the reporting entity should use the same approach to determining 
its organizational boundaries in the U.S. and outside the U.S.
    (b) Each reporting entity must keep separate reports on emissions or 
emission reductions that occur within its defined boundaries and those 
that occur outside its defined boundaries. Entities must also keep 
separate reports on emissions and emission reductions that occur outside 
the United

[[Page 105]]

States and those that occur within the United States.
    (c) An entity that intends to register its entity-wide emissions 
reductions must document and maintain its organizational boundary for 
accounting and reporting purposes.



Sec. 300.5  Submission of an entity statement.

    (a) Determining the type of reporting entity. The entity statement 
requirements vary by type of reporting entity. For the purposes of these 
guidelines, there are three types of entities:
    (1) Large emitters that intend to register emission reductions;
    (2) Small emitters that intend to register emission reductions; and
    (3) Emitters that intend to report, but not register emission 
reductions.
    (b) Choosing a start year. The first entity statement describes the 
make-up, operations and boundaries of the entity, as they existed in the 
start year.
    (1) For all entities, it is the year immediately preceding the first 
year for which the entity intends to register emission reductions and 
the last year of the initial base period(s).
    (2) For entities intending to register emission reductions, the 
start year may be no earlier than 2002, unless the entity has made a 
commitment to reduce its entity-wide emissions under the Climate Leaders 
or Climate VISION program. An entity that has made such a commitment may 
establish a start year derived from the base period of the commitment, 
as long as it is no earlier than 2000.
    (i) For a large emitter, the start year is the first year for which 
the entity submits a complete emissions inventory under the 1605(b) 
program.
    (ii) The entity's emissions in its start year or its average annual 
emissions over a period of up to four years ending in the start year 
determine whether it qualifies to begin reporting as a small emitter.
    (3) For entities not intending to register reductions, the start 
year may be no earlier than 1990.
    (c) Determining and maintaining large or small emitter reporting 
status. (1) Any entity that intends to register emission reductions can 
choose to participate as a large emitter, but only an entity that has 
demonstrated that its annual emissions are less than or equal to 10,000 
metric tons of CO2 equivalent may participate as a small 
emitter. To demonstrate that its annual emissions are less than or equal 
to 10,000 metric tons of CO2 equivalent, an entity must 
submit either an estimate of its emissions during its chosen start year 
or an estimate of its average annual emissions over a continuous period 
not to exceed four years of time ending in its chosen start year, as 
long as the operations and boundaries of the entity have not changed 
significantly during that period.
    (2) An entity must estimate its total emissions using methods 
specified in Chapter 1 of the Technical Guidelines (incorporated by 
reference, see Sec. 300.13) or by using the Simplified Emission 
Inventory Tool (SEIT) provided by EIA and also discussed in Chapter 1. 
The results of this estimate must be reported to EIA. [Note: emission 
estimates developed using SEIT may not be used to prepare, in whole or 
part, entity-wide emission inventories required for the registration of 
reductions.]
    (3) After starting to report, each small emitter must annually 
certify that the emissions-related operations and boundaries of the 
entity have not changed significantly since the previous report. A new 
estimate of total emissions must be submitted after any significant 
increase in emissions, any change in the operations or boundaries of the 
small emitter, or every five years, whichever occurs first. Small 
emitters with estimated annual emissions of over 9,000 metric tons of 
CO2 equivalent should re-estimate and submit their emissions 
annually. If an entity determines that it must report as a large 
emitter, then it must continue to report as a large emitter in all 
future years in order to ensure a consistent time series of reports. 
Once a small emitter becomes a large emitter, it must begin reporting in 
conformity with the reporting requirements for large emitters.
    (d) Entity statements for large emitters intending to register 
reductions. When a large emitter intending to register emission 
reductions first reports under these guidelines, it must provide the

[[Page 106]]

following information in its entity statement:
    (1) The name to be used to identify the participating entity;
    (2) The legal basis of the named entity;
    (3) The criteria used to determine:
    (i) The organizational boundaries of the entity, if other than 
financial control; and
    (ii) The sources of emissions included or excluded from the entity's 
reports, such as sources excluded as de minimis emissions;
    (4) The names of any parent or holding companies the activities of 
which will not be covered comprehensively by the entity's reports;
    (5) The names of any large subsidiaries or organizational units 
covered comprehensively by the entity's reports. All subsidiaries of the 
entity must be covered by the entity's reports, but only large 
subsidiaries must be specifically identified in the entity statement;
    (6) A list of each country where operations occur, if the entity is 
including any non-U.S. operations in its report;
    (7) A description of the entity and its primary U.S. economic 
activities, such as electricity generation, product manufacturing, 
service provider or freight transport; for each country listed under 
paragraph (d)(6) of this section, the large emitter should describe the 
economic activity in that country.
    (8) A description of the types of emission sources or sinks to be 
covered in the entity's emission inventories, such as fossil fuel power 
plants, manufacturing facilities, commercial office buildings or heavy-
duty vehicles;
    (9) The names of other entities that substantially share the 
ownership or operational control of sources that represent a significant 
part of the reporting entity's emission inventories, and a certification 
that, to the best of the certifier's knowledge, the direct greenhouse 
gas emissions and sequestration in the entity's report are not included 
in reports filed by any of these other entities to the 1605(b) program; 
and
    (10) Identification of the start year.
    (e) Entity statements for small emitters intending to register 
reductions. When a small emitter intending to register emission 
reductions first reports under these guidelines, it must provide the 
following information in its entity statement:
    (1) The name to be used to identify the participating entity;
    (2) The legal basis of the named entity;
    (3) An identification of the entity's control over the activities 
covered by the entity's reports, if other than financial control;
    (4) The names of any parent or holding companies the activities of 
which will not be covered comprehensively by the entity's reports;
    (5) An identification or description of the primary economic 
activities of the entity, such as agricultural production, forest 
management or household operation; if any of the economic activities 
covered by the entity's reports occur outside the U.S., a listing of 
each country in which such activities occur;
    (6) An identification or description of the specific activity (or 
activities) and the emissions, avoided emissions or sequestration 
covered by the entity's report, such as landfill gas recovery or forest 
sequestration;
    (7) A certification that, to the best of the certifier's knowledge, 
the direct greenhouse gas emissions and sequestration in the entity's 
report are not included in reports filed by any other entities reporting 
to the 1605(b) program; and
    (8) Identification of the start year.
    (f) Entity statements for reporting entities not registering 
reductions. When a participant not intending to register emission 
reductions first reports under this part, it must, at a minimum, provide 
the following information in its entity statement:
    (1) The name to be used to identify the reporting entity;
    (2) The legal basis of the entity;
    (3) An identification of the entity's control over the activities 
covered by the entity's reports, if other than financial control;
    (4) A description of the entity and its primary economic activities, 
such as electricity generation, product manufacturing, service provider, 
freight transport, agricultural production, forest management or 
household operation; if any of the economic activities covered by the 
entity's reports occur

[[Page 107]]

outside the United States, a listing of each country in which such 
activities occur; and
    (5) A description of the types of emission sources or sinks, such as 
fossil fuel power plants, manufacturing facilities, commercial office 
buildings or heavy-duty vehicles, covered in the entity's reports of 
emissions or emission reductions.
    (g) Changing entity statements. (1) Reporting entities are required 
to annually review and, if necessary, update their entity statements.
    (2) From time to time, a reporting entity may choose to change the 
scope of activities included within the entity's reports or the level at 
which the entity wishes to report. A reporting entity may also choose to 
change its organizational boundaries, its base period, or other elements 
of its entity statement. For example, companies buy and sell business 
units, or equity share arrangements may change. In general, DOE 
encourages changes in the scope of reporting that expand the coverage of 
an entity's report and discourages changes that reduce the coverage of 
such reports unless they are caused by divestitures or plant closures. 
Any such changes should be reported in amendments to the entity 
statement, and major changes may warrant or require changes in the base 
values used to calculate emission reductions and, in some cases, the 
entity's base periods. Changes in the scope of reporting made on or 
before May 31 of a given calendar year must be reflected in the report 
submitted covering emissions and reductions for the following calendar 
year. Reporting entities may choose to postpone incorporating changes in 
the scope of reporting made after May 31 until submitting the report 
covering emissions and reductions for the year after the following 
calendar year. However, in no case should there be an interruption in 
the annual reports of entities registering emission reductions. Chapter 
2 of the Technical Guidelines (incorporated by reference, see Sec. 
300.13) provides more specific guidance on how such changes should be 
reflected in entity statements, reports, and emission reduction 
calculations.
    (h) Documenting changes in amended entity statements. A reporting 
entity's entity statement in subsequent reports should focus primarily 
on changes since the previous report. Specifically, the subsequent 
entity statement should report the following information:
    (1) For significant changes in the reporting entity's scope or 
organizational boundaries, the entity should document:
    (i) The acquisition or divestiture of discrete business units, 
subsidiaries, facilities, and plants;
    (ii) The closure or opening of significant facilities;
    (iii) The transfer of economic activity to or from specific 
subentities covered by the entity's reports, such as the transfer of 
operations to non-U.S. subsidiaries;
    (iv) Significant changes in land holdings (applies to entities 
reporting on greenhouse gas emissions or sequestration related to land 
use, land use change, or forestry);
    (v) Whether the reporting entity is reporting at a higher level of 
aggregation than it did in the previous report, and if so, a listing of 
the subsidiary entities that are now aggregated under a revised 
conglomerated entity, including a listing of any non-U.S. operations to 
be added and the specific countries in which these operations are 
located; and
    (vi) Changes in its activities or operations (e.g., changes in 
output, contractual arrangements, equipment and processes, outsourcing 
or insourcing of significant activities) that are likely to have a 
significant effect on emissions, together with an explanation of how it 
believes the changes in economic activity influenced its reported 
emissions or sequestrations.



Sec. 300.6  Emissions inventories.

    (a) General. The objective of an emission inventory is to provide a 
full accounting of an entity's emissions for a particular year, 
including direct emissions of the first six categories of gases listed 
in the definition of ``greenhouse gases'' in Sec. 300.2, indirect 
emissions specified in paragraph (e) of this section, and all 
sequestration or other changes in carbon stocks. An emission

[[Page 108]]

inventory must be prepared in accordance with Chapter 1 of the Technical 
Guidelines (incorporated by reference, see Sec. 300.13). An inventory 
does not include avoided emissions or any offset reductions, and is not 
subsequently adjusted to reflect future acquisitions, divestitures or 
other changes to the reporting entity (although a reporting entity often 
makes these types of adjustments when calculating emission reductions 
under the guidelines). Entity-wide inventories are a prerequisite for 
the registration of emission reductions by entities with average annual 
emissions of more than 10,000 metric tons of CO2 equivalent. 
Entities that have average annual emissions of less than or equal to 
10,000 metric tons of CO2 equivalent are eligible to register 
emission reductions associated with specific activities without also 
reporting an inventory of the total emissions, but such entities should 
inventory and report the emissions associated with the specific 
activity(ies) they do cover in their reports.
    (b) Quality requirements for emission inventories. The Technical 
Guidelines (incorporated by reference, see Sec. 300.13) usually 
identify more than one acceptable method of measuring or estimating 
greenhouse gas emissions. Each acceptable method is rated A, B, C or D, 
with A methods usually corresponding to the highest quality method 
available and D methods representing the lowest quality method that may 
be used. Each letter is assigned a numerical rating reflecting its 
relative quality, 4 for A methods, 3 for B methods, 2 for C methods and 
1 for D methods. Entities that intend to register emission reductions 
must use emission inventory methods that result in a quantity-weighted 
average quality rating of at least 3.0.
    (1) Entities may at any time choose to modify the measurement or 
estimation methods that they use for their current or future year 
emission inventories. Such modifications would enable entities to 
gradually improve the quality of the ratings over time, but prior year 
inventories may be modified only to correct significant errors.
    (2) Entities that have had their emission quantities and the 
quantity-weighted quality rating of their emissions inventory 
independently verified may report their emissions and average quality 
ratings by greenhouse gas, indirect emissions and sequestration, rather 
than by source or sink category.
    (3) Entities that certify that they have used only A or B methods, 
may forego indicating in their reports the quality ratings of the 
methods used and may forego calculating the quantity-weighted average 
quality of their emission inventories.
    (c) Using estimation methods not included in the Technical 
Guidelines. An entity may obtain DOE approval for the use of an 
estimation method not included in the Technical Guidelines (incorporated 
by reference, see Sec. 300.13) if the method covers sources not 
described in the Technical Guidelines, or if the method provides more 
accurate results for the entity's specific circumstances than the 
methods described in the Technical Guidelines. If an entity wishes to 
propose the use of a method that is not described in the Technical 
Guidelines, the entity must provide a written description of the method, 
an explanation of how the method is implemented (including data 
requirements), empirical evidence of the method's validity and accuracy, 
and a suggested rating for the method to DOE's Office of Policy and 
International Affairs (with a copy to EIA). DOE reserves the right to 
deny the request, or to assign its own rating to the method. By 
submitting this information, the entity grants permission to DOE to 
incorporate the method in a future revision of the Technical Guidelines.
    (d) Direct emissions inventories. Direct greenhouse gas emissions 
that must be reported are the emissions resulting from stationary or 
mobile sources within the organizational boundaries of an entity, 
including but not limited to emissions resulting from combustion of 
fossil fuels, process emissions, and fugitive emissions. Process 
emissions (e.g., PFC emissions from aluminum production) must be 
reported along with fugitive emissions (e.g., leakage of greenhouse 
gases from equipment).
    (e) Inventories of indirect emissions associated with purchased 
energy. (1) To provide a clear incentive for the users

[[Page 109]]

of electricity and other forms of purchased energy to reduce demand, an 
entity must include the indirect emissions from the consumption of 
purchased electricity, steam, and hot or chilled water in the entity's 
inventory as indirect emissions. To avoid double counting among 
entities, the entity must report all indirect emissions separately from 
its direct emissions. Entities should use the methods for quantifying 
indirect emissions specified in the Technical Guidelines (incorporated 
by reference, see Sec. 300.13).
    (2) Entities may choose to report other forms of indirect emissions, 
such as emissions associated with employee commuting, materials consumed 
or products produced, although such other indirect emissions may not be 
included in the entity's emission inventory and may not be the basis for 
registered emission reductions. All such reports of other forms of 
indirect emissions must be distinct from reports of indirect emissions 
associated with purchased energy and must be based on emission 
measurement or estimation methods identified in the Technical Guidelines 
(incorporated by reference, see Sec. 300.13) or approved by DOE.
    (f) Entity-level inventories of changes in terrestrial carbon 
stocks. Annual changes in managed terrestrial carbon stocks should be 
comprehensively assessed and reported across the entity, and the net 
emissions resulting from such changes included in the entity's emissions 
inventory. Entities should use the methods for estimating changes in 
managed terrestrial carbon stocks specified in the Technical Guidelines 
(incorporated by reference, see Sec. 300.13).
    (g) Treatment of de minimis emissions and sequestration. (1) 
Although the goal of the entity-wide reporting requirement is to provide 
an accurate and comprehensive estimate of total emissions, there may be 
small emissions from certain sources that are unduly costly or otherwise 
difficult to measure or reliably estimate annually. An entity may 
exclude particular sources of emissions or sequestration if the total 
quantities excluded represent less than or equal to 3 percent of the 
total annual CO2 equivalent emissions of the entity. The 
entity must identify the types of emissions excluded and provide an 
estimate of the annual quantity of such emissions using methods 
specified in the Technical Guidelines (incorporated by reference, see 
Sec. 300.13) or by using the Simplified Emissions Inventory Tool 
(SEIT). The results of this estimate of the entity's total excluded 
annual emissions must be reported to DOE together with the entity's 
initial entity statement.
    (2) After starting to report, each reporting entity that excludes 
from its annual reports any de minimis emissions must re-estimate the 
quantity of excluded emissions after any significant increase in such 
emissions, or every five years, whichever occurs sooner.
    (h) Separate reporting of domestic and international emissions. Non-
U.S. emissions included in an entity's emission inventory must be 
separately reported and clearly distinguished from emissions originating 
in the U.S. Entities must identify any country-specific factors used in 
the preparation of such reports.
    (i) Covered gases. Entity-wide emissions inventories must include 
the emissions of the first six categories of named gases listed in the 
definition of ``greenhouse gases'' in Sec. 300.2. Entities may report 
chlorofluorocarbons and other greenhouse gases with quantifiable climate 
forcing effects as long as DOE has established a method for doing so, 
but such gases must be reported separately and emission reductions, if 
any, associated with such other gases are not eligible for registration.
    (j) Units for reporting. Emissions and sequestration should be 
reported in terms of the mass (not volume) of each gas, using metric 
units (e.g., metric tons of methane). Entity-wide and subentity 
summations of emissions and reductions from multiple sources must be 
converted into CO2 equivalent units using the global warming 
potentials for each gas in the International Panel on Climate Change's 
Third Assessment (or most recent) Report, as specified in the Technical 
Guidelines (incorporated by reference, see Sec. 300.13). Entities 
should specify the units used (e.g., kilograms, or metric tons). 
Entities may need to use the standard conversion factors specified in 
the Technical Guidelines to

[[Page 110]]

convert existing data into the common units required in the entity-level 
report. Emissions from the consumption of purchased electricity must be 
calculated by region (from the list provided by DOE in the Technical 
Guidelines) or country, if outside the United States. Consumption of 
purchased steam or chilled/hot water must be reported according to the 
type of system and fuel used to generate it (from the list provided by 
DOE in the Technical Guidelines). Entities must convert purchased energy 
to CO2 equivalents using the conversion factors in the 
Technical Guidelines. Entities should also provide the physical 
quantities of each type of purchased energy covered by their reports.



Sec. 300.7  Net emission reductions.

    (a) Entities that intend to register emission reductions achieved 
must comply with the requirements of this section. Entities may 
voluntarily follow these procedures if they want to demonstrate the 
achievement of net, entity-wide reductions for years prior to the 
earliest year permitted for registration. Only large emitters must 
follow the requirements of paragraph (b) of this section, but small 
emitters may do so voluntarily. Only entities that qualify as small 
emitters may use the special procedures in paragraph (c) of this 
section. Entities seeking to register emission reductions achieved by 
other entities (offsets) must certify that these emission reductions 
were calculated in a manner consistent with the requirements of 
paragraph (d) of this section and use the emission reduction calculation 
methods identified in Sec. 300.8. All entities seeking to register 
emission reductions must comply with the requirements of paragraph (e) 
of this section. Only reductions in the emissions of the first six 
categories of gases listed in the definition of ``greenhouse gases'' in 
Sec. 300.2 are eligible for registration.
    (b) Assessing net emission reductions for large emitters. (1) 
Entity-wide reporting is a prerequisite for registering emission 
reductions by entities with average annual emissions of more than 10,000 
metric tons of CO2 equivalent. Net annual entity-wide 
emission reductions must be based, to the maximum extent practicable, on 
a full assessment and sum total of all changes in an entity's emissions, 
eligible avoided emissions and sequestration relative to the entity's 
established base period(s). This assessment must include all entity 
emissions, including the emissions associated with any non-U.S. 
operations covered by the entity statement, although the reductions 
achieved by non-U.S. operations must be separately totaled prior to 
being integrated with the net emission reductions achieved by U.S. 
operations. It must include the annual changes in the total emissions of 
the entity, including the total emissions of each of the subentities 
identified in its entity statement. All changes in emissions, avoided 
emissions, and sequestration must be determined using methods that are 
consistent with the guidelines described in Sec. 300.8 of this part.
    (2) If it is not practicable to assess the changes in net emissions 
resulting from certain entity activities using at least one of the 
methods described in Sec. 300.8 of this part, the entity may exclude 
them from its estimate of net emission reductions. The entity must 
identify as one or more distinct subentities the sources of emissions 
excluded for this reason and describe the reasons why it was not 
practicable to assess the changes that had occurred. DOE believes that 
few emission sources will be excluded for this reason, but has 
identified at least two situations where such an exclusion would be 
warranted. For example, it is likely to be impossible to assess the 
emission changes associated with a new manufacturing plant that produces 
a product for which the entity has no historical record of emissions or 
emissions intensity (emissions per unit of product output). However, 
once the new plant has been operational for at least a full year, a base 
period and base value(s) for the new plant could be established and its 
emission changes assessed in the following year. Until the emission 
changes of this new subentity can be assessed, it should be identified 
in the entity's report as a subentity for which no assessment of 
emission changes is practicable. The other example involves a subentity 
that has reduced its

[[Page 111]]

output below the levels of its base period. In such a case, the 
subentity could not use the absolute emissions method and may also be 
unable to identify an effective intensity metric or other method.
    (3) In calculating its net annual emission reductions, an entity 
should exclude any emissions or sequestration that have been excluded 
from the entity's inventory. The entity should also exclude all de 
minimis and biogenic emissions that are excluded from the entity's 
inventory of greenhouse gas emissions from its assessments of emission 
changes.
    (c) Assessing emission reductions for entities with small emissions. 
(1) Entities with average annual emissions of less than or equal to 
10,000 metric tons of CO2 equivalent are not required to 
inventory their total emissions or assess all changes in their 
emissions, eligible avoided emissions and sequestration to qualify for 
registered reductions. These entities may register emission reductions 
that have occurred since 2002 and that are associated with one or more 
specific activities, as long as they:
    (i) Perform a complete assessment of the annual emissions and 
sequestration associated with each of the activities upon which they 
report, using methods that meet the same quality requirements applicable 
to entity-wide emission inventories; and
    (ii) Determine the changes in the emissions, eligible avoided 
emissions or sequestration associated with each of these activities.
    (2) An entity reporting as a small emitter must report on one or 
more specific activities and is encouraged, but not required to report 
on all activities occurring within the entity boundary. Examples of 
small emitter activities include: vehicle operations; product 
manufacturing processes; building operations or a distinct part thereof, 
such as lighting; livestock operations; crop management; and power 
generation. For example, a farmer managing several woodlots and also 
producing a wheat crop may report emission reductions associated with 
managing an individual woodlot. However, the farmer must also assess and 
report the net sequestration resulting from managing all the woodlots 
within the entity's boundary. The small emitter is not required to 
report on emissions or reductions associated with growing the wheat 
crop.
    (3) A small emitter must certify that the reductions reported were 
not caused by actions likely to cause increases in emissions elsewhere 
within the entity's operations. This certification should be based on an 
assessment of the likely direct and indirect effects of the actions 
taken to reduce greenhouse gas emissions.
    (d) Net emission reductions achieved by other entities (offset 
reductions or emission reductions submitted by aggregators). A reporting 
entity or aggregator under certain conditions may report or register all 
or some of the net emission reductions achieved by entities that choose 
not to report under the section 1605(b) program. In all cases, an 
agreement must exist between the reporting entity or aggregator and the 
other entity that specifies the quantity of the emission reductions (or 
increases) achieved by the other entity that may be reported or 
registered as an offset reduction by the reporting entity or aggregator. 
A large emitter that is reporting on behalf of other entities must meet 
all of the requirements applicable to large emitters, including 
submission of an entity statement, an emissions inventory, and an 
entity-wide assessment of emission reductions. If an aggregator is a 
small emitter, it may choose to report only on the activities, emissions 
and emission reductions of the entities on behalf of which it is 
reporting and not to report on any of its own activities or emission 
reductions. The reporting entity or aggregator must include in its 
report all of the information on the other entity, including an entity 
statement, an emissions inventory (when required), and an assessment of 
emission reductions that would be required if the other entity were 
directly reporting to EIA. The net emissions reductions (or increases) 
of each other entity will be evaluated separately by EIA to determine 
whether they are eligible for registration in accordance with the 
guidelines of this part. Those registered reductions (or increases) 
assigned by the

[[Page 112]]

other entity, by agreement, to a reporting entity or aggregator will be 
included in EIA's summary of all registered offset reductions for that 
entity or aggregator. If the agreement between the reporting entity and 
other entity is discontinued, for any reason, the reporting entity must 
inform EIA and must identify any emission reductions previously reported 
that could be attributable to an increase in the carbon stocks of the 
other entity. Such reductions will be removed by EIA from the records of 
the reporting entity's offset reductions.
    (e) Net emission reductions to be reported by other entities as 
offset reductions. Entities must identify in their report the quantity 
of any net emission reductions covered by the report, if any, that 
another entity will report as an offset reduction, including the name of 
the other entity;
    (f) Adjusting for year-to-year increases in net emissions. (1) 
Normally, net annual emission reductions for an entity are calculated by 
summing the net annual changes in emissions, eligible avoided emissions 
and sequestration, as determined using the calculation methods 
identified in Sec. 300.8 and according to the procedures described in 
paragraph (b) of this section for large emitters, paragraph (c) for 
small emitters of this section for small emitters, and paragraph (d) of 
this section for offsets. However, if the entity experienced a net 
increase in emissions for one or more years, these increases must be 
reported and taken into account in calculating any future year 
reductions. If the entity subsequently achieves net annual emission 
reductions, the net increases experienced in the preceding year(s) must 
be more than offset by these reductions before the entity can once again 
register emission reductions. For example, if an entity achieved a net 
emission reduction of 5,000 metric tons of CO2 equivalent in 
its first year, a net increase of 2,000 metric tons in its second year, 
and a net reduction of 3,000 metric tons in its third year, it would be 
able to register a 5,000 metric ton reduction in its first year, no 
reduction in its second year, and a 1,000 metric ton reduction in its 
third year (3,000-2,000). The entity must file full reports for each of 
these three years. Its report for the second year would indicate the net 
increase in emissions and this increase would be noted in EIA's summary 
of the entity's report for that year and for any future year, until the 
emissions increase was entirely offset by subsequent emission 
reductions. If this same entity achieved a net reduction of only 1,000 
metric tons in its third year, it would not be able to register 
additional reductions until it had, in some future year, offset more 
than its second year increase of 2,000 metric tons.
    (2) [Reserved]



Sec. 300.8  Calculating emission reductions.

    (a) Choosing appropriate emission reduction calculation methods. (1) 
An entity must choose the method or methods it will use to calculate 
emission reductions from the list provided in paragraph (h) of this 
section. Each of the calculation methods has special characteristics 
that make it applicable to only certain types of emissions and 
activities. An entity should select the appropriate calculation method 
based on several factors, including:
    (i) How the entity's subentities are defined;
    (ii) How the reporter will gather and report emissions data; and
    (iii) The availability of other types of data that might be needed, 
such as production or output data.
    (2) For some entities, a single calculation method will be 
sufficient, but many entities may need to apply more than one method 
because discrete components of the entity require different calculation 
methods. In such a case, the entity will need to select a method for 
each subentity (or discrete component of the entity with identifiable 
emission or reductions). The emissions and output measure (generally a 
physical measure) of each subentity must be clearly distinguished and 
reported separately. Guidance on the selection and specification of 
calculation methods is provided in Chapter 2 of the Technical Guidelines 
(incorporated by reference, see Sec. 300.13).

[[Page 113]]

    (b) Identifying subentities for calculating reductions. If more than 
one calculation method is to be used, an entity must specify the portion 
of the entity (the subentity) to which each method will be applied. Each 
subentity must be clearly identified. From time to time, it may be 
necessary to modify existing or create new subentities. The entity must 
provide to EIA a full description of such changes, together with an 
explanation of why they were required.
    (c) Choosing a base period for calculating reductions. In general, 
the base period used in calculating emission reductions is the single 
year or up to four-year period average immediately preceding the first 
year of calculated emission reductions.
    (d) Establishing base values. To calculate emission reductions, an 
entity must establish a base value against which to compare reporting 
year performance. The minimum requirements for base values for each type 
of calculation method are specified in Chapter 2 of the Technical 
Guidelines (incorporated by reference, see Sec. 300.13). In most cases, 
an historic base value, derived from emissions or other data gathered 
during the base period, is the minimum requirement specified. Entities 
may, however, choose to establish base values that are more stringent 
than the base values derived from the methods specified in Chapter 2 of 
the Technical Guidelines as long as their report indicates the rationale 
for the alternative base value and demonstrates that it would result in 
a smaller quantity of emission reductions.
    (e) Emission reduction and subentity statements. For each subentity, 
an entity must submit to EIA the following information:
    (1) An identification and description of the method used to 
calculate emission reductions, including:
    (i) The type of calculation method;
    (ii) The measure of output used (if any); and
    (iii) The method-specific base period for which any required base 
value will be calculated.
    (2) The base period used in calculating reductions. When an entity 
starts to report, the base period used in calculating reductions must 
end in the start year. However, over time the reporting entity may find 
it necessary to revise or establish new base periods and base values in 
response to significant changes in processes or output of the subentity.
    (3) A description of the subentity and its primary economic activity 
or activities, such as electricity generation, product manufacturing, 
service provider, freight transport, or household operation; and
    (4) A description of the emission sources or sinks covered, such as 
fossil fuel power plants, manufacturing facilities, commercial office 
buildings or heavy-duty vehicles.
    (f) Changes in calculation methods, base periods and base values. 
When significant changes occur in the composition or output of reporting 
entities, a reporting entity may need to change previously specified 
calculation methods, base periods or base values. A reporting entity 
should make such changes only if necessary and it should fully document 
the reasons for any changes. The Technical Guidelines (incorporated by 
reference, see Sec. 300.13) describe when such changes should be made 
and what information on such changes must be provided to DOE. In 
general, such changes should not result in any alterations to previously 
reported or registered emission reductions. A reporting entity may alter 
previously reported or registered emission reductions only if necessary 
to correct significant errors.
    (g) Continuous reporting. To ensure that the summation of entity 
annual reports accurately represents net, multi-year emission 
reductions, an entity must submit a report every year, beginning with 
the first reduction year. An entity may use a specific base period to 
determine emission reductions in a given future year only if the entity 
has submitted qualified reports for each intervening year. If an 
interruption occurs in the annual reports of an entity, the entity must 
subsequently report on all missing years prior to qualifying for the 
registration of additional emission reductions.

[[Page 114]]

    (h) Calculation methods. An entity must calculate any change in 
emissions, avoided emissions or sequestration using one or more of the 
methods described in this paragraph and in the Technical Guidelines 
(incorporated by reference, see Sec. 300.13).
    (1) Changes in emissions intensity. An entity may use emissions 
intensity as a basis for determining emission reductions as long as the 
entity selects a measure of output that is:
    (i) A reasonable indicator of the output produced by the entity;
    (ii) A reliable indicator of changes in the entity's activities;
    (iii) Related to emissions levels; and
    (iv) Any appropriate adjustments for acquisitions, divestitures, 
insourcing, outsourcing, or changes in products have been made, as 
described in the Technical Guidelines (incorporated by reference, see 
Sec. 300.13).
    (2) Changes in absolute emissions. An entity may use changes in the 
absolute (actual) emissions (direct and/or indirect) as a basis for 
determining net emission reductions as long as the entity makes only 
those adjustments required by the Technical Guidelines (incorporated by 
reference, see Sec. 300.13). An entity intending to register emission 
reductions may use this method only if the entity demonstrates in its 
report that any reductions derived from such changes were not achieved 
as a result of reductions in the output of the entity, and certifies 
that emission reductions are not the result of major shifts in the types 
of products or services produced. Entities may report, but not register, 
such reductions even if the output associated with such emissions is 
declining.
    (3) Changes in carbon storage (for actions within entity 
boundaries). An entity may use changes in carbon storage as a basis for 
determining net emission reductions as long as the entity uses 
estimation and measurement methods that comply with the Technical 
Guidelines (incorporated by reference, see Sec. 300.13), and has 
included an assessment of the net changes in all sinks in its inventory.
    (4) Changes in avoided emissions (for actions within entity 
boundaries). An entity may use changes in avoided emissions to determine 
its emission reductions. Avoided emissions eligible to be included in 
the calculation of net emission reductions that qualify for registration 
include those associated with the sale of electricity, steam, hot water 
or chilled water generated from non-emitting or low-emitting sources as 
a basis for determining net emission reductions as long as:
    (i) The measurement and calculation methods used comply with the 
Technical Guidelines (incorporated by reference, see Sec. 300.13);
    (ii) The entity certifies that any increased sales were not 
attributable to the acquisition of a generating facility that had been 
previously operated, unless the entity's base period includes generation 
values from the acquired facility's operation prior to its acquisition; 
and
    (iii) Generators of distributed energy that have net emissions in 
their base period and intend to report reductions resulting from changes 
in eligible avoided emissions, use a method specified in the Technical 
Guidelines (incorporated by reference, see Sec. 300.13) that integrates 
the calculation of reductions resulting from both changes in emissions 
intensity and changes in avoided emissions.
    (5) Action-specific emission reductions (for actions within entity 
boundaries). A number of source- or situation-specific methods are 
provided in the Technical Guidelines and these methods must be used to 
assess the annual changes in emissions for the specific sources or 
situation addressed by these methods. In addition, a generic action-
specific method is identified in the Technical Guidelines. An entity 
intending to register reductions may use the generic action-specific 
approach only if it is not possible to measure accurately emission 
changes by using one of the methods identified in paragraphs (h)(1) 
through (h)(4) of this section. Entities that intend to register 
reductions and that use the generic action-specific approach must 
explain why it is not possible to use any of these other methods. An 
entity not intending to register reductions may use the generic action-
specific method to determine emission reductions, as long as the entity 
demonstrates that the estimate is based on analysis that:

[[Page 115]]

    (i) Uses output, utilization and other factors that are consistent, 
to the maximum extent practicable, with the action's actual performance 
in the year for which reductions are being reported;
    (ii) Excludes any emission reductions that might have resulted from 
reduced output or were caused by actions likely to be associated with 
increases in emissions elsewhere within the entity's operations; and
    (iii) Uses methods that are in compliance with the Technical 
Guidelines (incorporated by reference, see Sec. 300.13).
    (i) Summary description of actions taken to reduce emissions. Each 
reported emission reduction must be accompanied by an identification of 
the types of actions that were the likely cause of the reductions 
achieved. Entities are also encouraged to include in their reports 
information on the benefits and costs of the actions taken to reduce 
greenhouse gas emissions, such as the expected rates of return, life 
cycle costs or benefit to cost ratios, using appropriate discount rates.
    (j) Emission reductions associated with plant closings, voluntary 
actions and government (including non-U.S. regulatory regimes) 
requirements. (1) Each report of emission reductions must indicate 
whether the reported emission reductions were the result, in whole or in 
part, of plant closings, voluntary actions, or government requirements. 
EIA will presume that reductions that were not the result of plant 
closings or government requirements are the result of voluntary actions.
    (2) If emission reductions were, in whole or in part, the direct 
result of plant closings that caused a decline in output, the report 
must identify the reductions as such; these reductions do not qualify 
for registration. EIA will presume that reductions calculated using the 
emissions intensity method do not result from a decline in output.
    (3) If the reductions were associated, in whole or part, with U.S. 
or non-U.S. government requirements, the report should identify the 
government requirement involved and the effect these requirements had on 
the reported emission reductions. If, as a result of the reduction, a 
non-U.S. government issued to the reporting entity a credit or other 
financial benefit or regulatory relief, the report should identify the 
government requirement involved and describe the specific form of 
benefit or relief provided.
    (k) Determining the entity responsible for emission reductions. The 
entity that EIA will presume to be responsible for emission reduction, 
avoided emission or sequestered carbon is the entity with financial 
control of the facility, land or vehicle which generated the reported 
emissions, generated the energy that was sold so as to avoid other 
emissions, or was the place where the sequestration action occurred. If 
control is shared, reporting of the associated emission reductions 
should be determined by agreement between the entities involved so as to 
avoid double-counting; this agreement must be reflected in the entity 
statement and in any report of emission reductions. EIA will presume 
that an entity is not responsible for any emission reductions associated 
with a facility, property or vehicle excluded from its entity statement.



Sec. 300.9  Reporting and recordkeeping requirements.

    (a) Starting to report under the guidelines. An entity may report 
emissions and sequestration on an annual basis beginning in any year, 
but no earlier than the base period of 1987-1990 specified in the Energy 
Policy Act of 1992. To be recognized under these guidelines, all reports 
must conform to the measurement methods established by the Technical 
Guidelines (incorporated by reference, see Sec. 300.13).
    (b) Revisions to reports submitted under the guidelines. (1) Once 
EIA has accepted a report under this part, it may be revised by the 
reporting entity only under the circumstances specified in this 
paragraph and related provisions of the Technical Guidelines 
(incorporated by reference, see Sec. 300.13). In general:
    (i) Revised reports may be submitted to correct errors that have a 
significant effect on previously estimated emissions or emission 
reductions; and
    (ii) Emission inventories may be revised in order to create a 
consistent time series based on improvements in

[[Page 116]]

the emission estimation or measurement techniques used.
    (2) Reporting entities must provide the corrected or improved data 
to EIA, together with an explanation of the significance of the change 
and its justification.
    (3) If a change in calculation methods (for inventories or 
reductions) is made for a particular year, the reporting entity must, if 
feasible, revise its base value to assure methodological consistency 
with the reporting year value.
    (c) Definition and deadline for annual reports. Entities must report 
emissions on a calendar year basis, from January 1 to December 31. To be 
included in the earliest possible EIA annual report of greenhouse gas 
emissions reported under this part, entity reports that have not been 
independently verified must be submitted to DOE no later than July 1 for 
emissions occurring during the previous calendar year. Reports that have 
been independently verified must be submitted by September 1 for 
emissions occurring during the previous year.
    (d) Recordkeeping. Entities intending to register reductions must 
maintain adequate supporting records of base period data for the 
duration of their participation in the 1605(b) program. Supporting 
records for all reporting year data must be maintained for at least 
three years subsequent to the relevant reporting year to enable 
verification of all information reported. The records should document 
the basis for the entity's report to EIA, including:
    (1) The content of entity statements, including the identification 
of the specific facilities, buildings, land holding and other operations 
or emission sources covered by the entity's reports and the legal, 
equity, operational and other bases for their inclusion;
    (2) Information on the identification and assessment of changes in 
entity boundaries, processes or products that might have to be reported 
to EIA;
    (3) Any agreements or relevant communications with other entities or 
third parties regarding the reporting of emissions or emission 
reductions associated with sources the ownership or operational control 
of which is shared;
    (4) Information on the methods used to measure or estimate 
emissions, and the data collection and management systems used to gather 
and prepare this data for inclusion in reports;
    (5) Information on the methods used to calculate emission 
reductions, including the basis for:
    (i) The selection of the specific output measures used, and the data 
collection and management systems used to gather and prepare output data 
for use in the calculation of emission reductions;
    (ii) The selection and modification of all base years, base periods 
and baselines used in the calculation of emission reductions;
    (iii) Any baseline adjustments made to reflect acquisitions, 
divestitures or other changes;
    (iv) Any models or other estimation methods used; and
    (v) Any internal or independent verification procedures undertaken.
    (e) Confidentiality. DOE will protect trade secret and commercial or 
financial information that is privileged or confidential as provided in 
5 U.S.C. 552(b)(4). An entity must clearly indicate in its 1605(b) 
report the information for which it requests confidentiality. DOE will 
handle requests for confidentiality of information submitted in 1605(b) 
reports in accordance with the process established in DOE's Freedom of 
Information regulations at 10 CFR Sec. 1004.11.



Sec. 300.10  Certification of reports.

    (a) General requirement and certifying official: All reports 
submitted to EIA must include a certification statement, as provided in 
paragraph (b) of this section, signed by a certifying official of the 
reporting entity. A household report may be certified by one of its 
members. All other reports must be certified by the chief executive 
officer, agency head, or an officer or employee of the entity who is 
responsible for reporting the entity's compliance with environmental 
regulations.
    (b) Certification statement requirements. All entities, whether 
reporting or registering reductions, must certify the following:
    (1) The information reported is accurate and complete;

[[Page 117]]

    (2) The information reported has been compiled in accordance with 
this part; and
    (3) The information reported is consistent with information 
submitted in prior years, if any, or any inconsistencies with prior 
year's information are documented and explained in the entity statement.
    (c) Additional requirements for registering. The certification 
statement of an entity registering reductions must also certify that:
    (1) The entity took reasonable steps to ensure that direct 
emissions, emission reductions, and/or sequestration reported are 
neither double counted nor reported by any other entity. Reasonable 
steps include telephone, fax, letter, or e-mail communications to ensure 
that another entity does not intend to report the same emissions, 
emission reductions, and/or sequestration to DOE. Direct communications 
of this kind with participants in demand-side management or other 
programs directed at very small emitters are not required;
    (2) Any emission reductions reported or registered by the entity 
that were achieved by another entity (other than a very small emitter 
that participated in a demand-side management or other program) are 
included in the entity's report only if:
    (i) The other entity does not intend to report or register theses 
reductions directly;
    (ii) There exists a written agreement with each other entity 
providing that the reporting entity is the entity entitled to report or 
register these emission reductions; and
    (iii) The information reported on the other entity would meet the 
requirements of this part if the entity were reporting directly to DOE;
    (3) None of the emissions, emission reductions, or sequestration 
reported were produced by shifting emissions to other entities or to 
non-reporting parts of the entity;
    (4) None of any reported changes in avoided emissions associated 
with the sale of electricity, steam, hot or chilled water generated from 
non-emitting or low-emitting sources are attributable to the acquisition 
of a generating facility that has been previously operated, unless the 
entity's base period includes generation values from the acquiring 
facility's operation prior to its acquisition;
    (5) The entity maintains records documenting the analysis and 
calculations underpinning the data reported on this form and records 
documenting the analysis and calculations underpinning the base values 
used in calculating annual reductions are maintained in accordance with 
Sec. 300.9(d) of this part; and
    (6) The entity has, or has not, obtained independent verification of 
the report, as described in Sec. 300.11.



Sec. 300.11  Independent verification.

    (a) General. Entities are encouraged to have their annual reports 
reviewed by independent and qualified auditors, as described in 
paragraphs (b), (c), and (f) of this section.
    (b) Qualifications of verifiers. (1) DOE envisions that independent 
verification will be performed by professional verifiers (i.e., 
individuals or companies that provide verification or ``attestation'' 
services). EIA will consider a report to the program to be independently 
verified if:
    (i) The lead individual verifier and other members of the 
verification team are accredited by one or more independent and 
nationally-recognized accreditation programs, described in paragraph (c) 
of this section, for the types of professionals needed to determine 
compliance with DOE's 1605(b) guidelines;
    (ii) The lead verifier has experience managing an auditing or 
verification process, including the recruitment and allocation of other 
individual verifiers, and has been empowered to make decisions relevant 
to the provision of a verification statement; and
    (iii) All members of a verification team have education, training 
and/or professional experience that matches the tasks performed by the 
individual verifiers, as deemed necessary by the verifier accreditation 
program.
    (2) As further guidance, all members of the verification team should 
be familiar with:
    (i) The subject matter covered by the scope of the verification;
    (ii) The requirements of this part;

[[Page 118]]

    (iii) Greenhouse gas emission and emission reduction quantification;
    (iv) Data and information auditing sampling methods; and
    (v) Risk assessment and methodologies and materiality analysis 
procedures outlined by other domestic and international standards.
    (3) An individual verifier should have a professional degree or 
accreditation in engineering (environmental, industrial, chemical), 
accounting, economics, or a related field, supplemented by specific 
training and/or experience in emissions reporting and accounting, and 
should have his or her qualifications and continuing education 
periodically reviewed by an accreditation program. The skills required 
for verification are often cross-disciplinary. For example, an 
individual verifier reviewing a coal electric utility should be 
knowledgeable about mass balance calculations, fuel purchasing 
accounting, flows and stocks of coals, coal-fired boiler operation, and 
issues of entity definition.
    (4) Companies that provide verification services must use 
professionals that possess the necessary skills and proficiency levels 
for the types of entities for which they provide verification services. 
Continuing training may be required to ensure all individuals have up-
to-date knowledge regarding the tasks they perform.
    (c) Qualifications of organizations accrediting verifiers. 
Organizations that accredit individual verifiers must be nationally 
recognized certification programs. They may include, but are not limited 
to the: American Institute of Certified Public Accountants; American 
National Standards Institute's Registrar Accreditation Board program for 
Environmental Management System auditors (ANSI-RAB-EMS); Board of 
Environmental, Health and Safety Auditor Certification: California 
Climate Action Registry; Clean Development Mechanism Executive Board; 
and the United Kingdom Accreditation Scheme.
    (d) Scope of verification. (1) As part of any independent 
verification, qualified verifiers must use their expertise and 
professional judgment to verify for accuracy, completeness and 
consistency with DOE's guidelines of:
    (i) The content of entity statements, annual reports and the 
supporting records maintained by the entity;
    (ii) The representation in entity statements (or lack thereof) of 
any significant changes in entity boundaries, products, or processes;
    (iii) The procedures and methods used to collect emissions and 
output data, and calculate emission reductions (for entities with widely 
dispersed operations, this process should include on-site reviews of a 
sample of the facilities);
    (iv) Relevant personnel training and management systems; and
    (v) Relevant quality assurance/quality control procedures.
    (2) DOE expects qualified verifiers to refer to the growing body of 
literature on methods of evaluating the elements listed in paragraph 
(d)(1) of this section, such as the California Climate Action Registry 
Certification Protocol, the Climate Leaders Inventory Management Plan 
Checklist, and the draft ISO 14064.3 Protocol for Validation, 
Verification and Certification.
    (e) Verification statement. Both the verifier and, if relevant, an 
officer of the company providing the verification service must sign the 
verification statement. The verification statement shall attest to the 
following:
    (1) The verifier has examined all components listed in paragraph (d) 
of this section;
    (2) The information reported in the verified entity report and this 
verification statement is accurate and complete;
    (3) The information reported by the entity has been compiled in 
accordance with this part;
    (4) The information reported on the entity report is consistent with 
information submitted in prior years, if any, or any inconsistencies 
with prior year's information are documented and explained in the entity 
statement;
    (5) The verifier used due diligence to assure that direct emissions, 
emission reductions, and/or sequestration reported are not reported by 
any other entity;
    (6) Any emissions, emission reductions, or sequestration that were

[[Page 119]]

achieved by a third-party entity are included in this report only if 
there exists a written agreement with each third party indicating that 
they have agreed that the reporting entity should be recognized as the 
entity entitled to report these emissions, emission reductions, or 
sequestration;
    (7) None of the emissions, emission reductions, or sequestration 
reported was produced by shifting emissions to other entities or to non-
reporting parts of the entity;
    (8) No reported changes in avoided emissions associated with the 
sale of electricity, steam, hot or chilled water generated from non-
emitting or low-emitting sources are attributable to the acquisition of 
a generating facility that has been previously operated, unless the base 
year generation values are derived from records of the facility's 
operation prior to its acquisition;
    (9) The verifying entity has procedures in place for the maintenance 
of records that are sufficient to document the analysis and calculations 
underpinning this verification. The verifying entity shall maintain such 
records related to base period data submitted by the reporting entity 
for the duration of the reporting entity's participation in the 1605(b) 
program and records related to all other verified data for a period of 
no less than three years; and
    (10) The independent verifier is not owned in whole or part by the 
reporting entity, nor provides any ongoing operational or support 
services to the entity, except services consistent with independent 
financial accounting or independent certification of compliance with 
government or private standards.
    (f) Qualifying as an independent verifier. An independent verifier 
may not be owned in whole or part by the reporting entity, nor may it 
provide any ongoing operational or support services to the entity, 
except services consistent with independent financial accounting or 
independent certification of compliance with government or private 
standards.



Sec. 300.12  Acceptance of reports and registration of entity
emission reductions.

    (a) Acceptance of reports. EIA will review all reports to ensure 
they are consistent with this part and with the Technical Guidelines 
(incorporated by reference, see Sec. 300.13). EIA will also review all 
reports for completeness, internal consistency, arithmetic accuracy and 
plausibility. Subject to the availability of adequate resources, EIA 
intends to notify entities of the acceptance or rejection of any report 
within six months of its receipt.
    (b) Registration of emission reductions. EIA will review each 
accepted report to determine if emission reductions were calculated 
using an acceptable base period (usually ending no earlier than 2002), 
and to confirm that the report complies with the other provisions of 
this part. EIA will also review its records to verify that the reporting 
entity has submitted accepted annual reports for each year between the 
establishment of its base period and the year covered by the current 
report. EIA will notify the entity that reductions meeting these 
requirements have been credited to the entity as ``registered 
reductions'' which can be held by the reporting entity for use 
(including transfer to other entities) in the event a future program 
that recognizes such reductions is enacted into law.
    (c) Rejection of reports. If EIA does not accept a report or if it 
determines that emission reductions intended for registration do not 
qualify, EIA will return the report to the sender with an explanation of 
its inadequacies. The reporting entity may resubmit a modified report 
for further consideration at any time.
    (d) EIA database and summary reports. The Administrator of EIA will 
establish a publicly accessible database composed of all reports that 
meet the definitional, measurement, calculation, and certification 
requirements of these guidelines. EIA will maintain separate subtotals 
of direct emissions, indirect emissions and carbon fluxes. A portion of 
the database will provide summary information on the emissions and 
registered emission reductions of each reporting entity.

(or delegee), may sign and issue subpoenas for the attendance and 
testimony of witnesses and the production of relevant books, records, 
papers, and other documents, and administer oaths. Witnesses summoned 
under the provisions of this section shall be paid the same fees and 
mileage as are paid to witnesses in the courts of the United States. In 
case of contumacy by, or refusal to obey a subpoena served, upon any 
persons subject to parts 429, 430, or 431, the General Counsel (or 
delegee) may seek an order from the District Court of the United States 
for any District in which such person is found or resides or transacts 
business requiring such person to appear and give testimony, or to 
appear and produce documents. Failure to obey such order is punishable 
by such court as contempt thereof.



                         Subpart B_Certification



Sec. 429.10  Purpose and scope.

    This subpart sets forth the procedures for manufacturers to certify 
that their covered products and covered equipment comply with the 
applicable energy conservation standards.



Sec. 429.11  General sampling requirements for selecting units to
be tested.

    (a) When testing of covered products or covered equipment is 
required to comply with section 323(c) of the Act, or to comply with 
rules prescribed under section 324, 325, or 342, 344, 345 or 346 of the 
Act, a sample comprised of production units (or units representative of 
production units) of the basic model being tested must be selected at 
random and tested, and must meet the criteria found in Sec. Sec. 429.14 
through 429.62 of this subpart. Components of similar design may be 
substituted without additional testing if the substitution does not 
affect energy or water consumption. Any represented values of measures 
of energy efficiency, water efficiency, energy consumption, or water 
consumption for all individual models represented by a given basic model 
must be the same, except for central air conditioners and central air 
conditioning heat pumps, as specified in Sec. 429.16 of this subpart.
    (b) The minimum number of units tested shall be no less than two, 
except where:
    (1) A different minimum limit is specified in Sec. Sec. 429.14 
through 429.65 of this subpart; or
    (2) Only one unit of the basic model is produced, in which case, 
that unit must be tested and the test results must demonstrate that the 
basic model performs at or better than the applicable standard(s). If 
one or more units of the basic model are manufactured subsequently, 
compliance with the default sampling and representations provisions is 
required.

Sec. 429.12  General requirements applicable to certification 
reports.

    (a) Certification. Each manufacturer, before distributing in 
commerce any basic model of a covered product or covered equipment 
subject to an applicable energy conservation standard set forth in parts 
430 or 431, and annually thereafter on or before the dates provided in 
paragraph (d) of this section, shall submit a certification report to 
DOE certifying that each basic model meets the applicable energy 
conservation standard(s). The certification report(s) must be submitted 
to DOE in accordance with the submission procedures of paragraph (h) of 
this section.
    (b) Certification report. A certification report shall include a 
compliance statement (see paragraph (c) of this section), and for each 
basic model, the information listed in this paragraph (b).
    (1) Product or equipment type;
    (2) Product or equipment class (as denoted in the provisions of part 
430 or 431 of this chapter containing the applicable energy conservation 
standard);
    (3) Manufacturer's name and address;
    (4) Private labeler's name(s) and address(es) (if applicable);
    (5) Brand name;
    (6) For each brand, the basic model number and the manufacturer's 
individual model number(s) in that basic model with the following 
exceptions: For external power supplies that are certified based on 
design families, the design family model number and the

[[Page 140]]

individual manufacturer's model numbers covered by that design family 
must be submitted for each brand. For distribution transformers, the 
basic model number or kVA grouping model number (depending on the 
certification method) for each brand must be submitted. For commercial 
HVAC, WH, and refrigeration equipment, an individual manufacturer model 
number may be identified as a ``private model number'' if it meets the 
requirements of Sec. 429.7(b).
    (7) Whether the submission is for a new model, a discontinued model, 
a correction to a previously submitted model, data on a carryover model, 
or a model that has been found in violation of a voluntary industry 
certification program;
    (8) The test sample size (i.e., number of units tested for the basic 
model, or in the case of single-split system or single-package central 
air conditioners and central air conditioning heat pumps, or multi-
split, multi-circuit, or multi-head mini-split systems other than the 
``tested combination,'' for each individual combination or individual 
model). Enter ``0'' if an AEDM was used in lieu of testing (and in the 
case of central air conditioners and central air conditioning heat 
pumps, this must be indicated separately for each metric);
    (9) The certifying party's U.S. Customs and Border Protection (CBP) 
importer identification numbers assigned by CBP pursuant to 19 CFR 24.5,

procedure requirements under Sec. 430.27 or Sec. 431.401 of this 
chapter and the date(s) of such waiver(s);
    (11) Whether certification is based upon any exception relief from 
an applicable energy conservation standard and the date such relief was 
issued by DOE's Office of Hearings and Appeals;
    (12) If the test sample size is listed as ``0'' to indicate the 
certification is based upon the use of an alternate way of determining 
measures of energy conservation, identify the method used for 
determining measures of energy conservation (such as ``AEDM,'' or linear 
interpolation). Manufacturers of commercial packaged boilers, commercial 
water heating equipment, commercial refrigeration equipment, commercial 
HVAC equipment, and central air conditioners and central air 
conditioning heat pumps must provide the manufacturer's designation 
(name or other identifier) of the AEDM used; and

    (e) New model filing. (1) In addition to the annual filing schedule 
in paragraph (d) of this section, any new basic models must be certified 
pursuant to paragraph (a) of this section before distribution in 
commerce. A modification to a model that increases the model's energy or 
water consumption or decreases its efficiency resulting in re-rating 
must be certified as a new basic model pursuant to paragraph (a) of this 
section.
    (2) For general service fluorescent lamps or incandescent reflector 
lamps: Prior to or concurrent with the distribution of a new basic model 
each manufacturer shall submit an initial certification report listing 
the basic model number, lamp wattage, and date of first manufacture 
(i.e., production date) for that basic model. The certification report 
must also state how the manufacturer determined that the lamp meets or 
exceeds the energy conservation standards, including a description of 
any testing or analysis the manufacturer performed. Manufacturers of 
general service fluorescent lamps and incandescent reflector lamps shall 
submit the certification report required by paragraph (b) of this 
section within one year after the first date of new model manufacture.
    (3) For distribution transformers, the manufacturer shall submit all 
information required in paragraphs (b) and (c) of this section for the 
new basic model, unless the manufacturer has previously submitted to the 
Department a certification report for a basic model of distribution 
transformer that is in the same kVA grouping as the new basic model.
    (f) Discontinued model filing. When production of a basic model has 
ceased and it is no longer being sold or offered for sale by the 
manufacturer or private labeler, the manufacturer must report this 
discontinued status to DOE as part of the next annual certification 
report following such cessation. For each basic model, the report must 
include the information specified in paragraphs (b)(1) through (7) of 
this section, except that for integrated light-emitting diode lamps and 
for compact fluorescent lamps, the manufacturer must submit a full 
certification report, including all of the information required by 
paragraph (b) of this section and the product-specific information 
required by Sec. 429.56(b)(2) or Sec. 429.35(b)(2), respectively.
    (g) Third party submitters. A manufacturer may elect to use a third 
party to submit the certification report to DOE (for example, a trade 
association, independent test lab, or other authorized representative, 
including a private labeler acting as a third party submitter on behalf 
of a manufacturer); however, the manufacturer is responsible for 
submission of the certification report to DOE. DOE may refuse to accept 
certification reports from third party submitters who have failed to 
submit reports in accordance with the rules of this part. The third 
party submitter must complete the compliance statement as part of the 
certification report. Each manufacturer using a third party submitter 
must have an authorization form on file with DOE. The authorization form 
includes a compliance statement, specifies the third party authorized to 
submit certification reports on the manufacturer's behalf and provides 
the contact information and signature of a company official.
    (h) Method of submission. Reports required by this section must be 
submitted to DOE electronically at http://

[[Page 142]]

www.regulations.doe.gov/ccms (CCMS). A manufacturer or third party 
submitter can find product-specific templates for each covered product 
or covered equipment with certification requirements online at https://
www.regulations.doe.gov/ccms/templates.html. Manufacturers and third 
party submitters must submit a registration form, signed by an officer 
of the company, in order to obtain access to CCMS.
    (i) Compliance dates. For any product subject to an applicable 
energy conservation standard for which the compliance date has not yet 
occurred, a certification report must be submitted not later than the 
compliance date for the applicable energy conservation standard. The 
covered products enumerated below are subject to the stated compliance 
dates for initial certification:
    (1) Commercial warm air furnaces, packaged terminal air 
conditioners, and packaged terminal heat pumps, July 1, 2014;
    (2) Commercial gas-fired and oil-fired instantaneous water heaters 
less than 10 gallons and commercial gas-fired and oil-fired hot water 
supply boilers less than 10 gallons, October 1, 2014;
    (3) All other types of covered commercial water heaters except those 
specified in paragraph (i)(2) of this section, commercial packaged 
boilers with input capacities less than or equal to 2.5 million Btu/h, 
and self-contained commercial refrigeration equipment with solid or 
transparent doors, December 31, 2014;
    (4) Variable refrigerant flow air conditioners and heat pumps, March 
31, 2015;
    (5) Small, large, or very large air-cooled, water-cooled, 
evaporatively-cooled, and water-source commercial air conditioning and 
heating equipment, single package vertical units, computer room air 
conditioners, commercial packaged boilers with input capacities greater

                                                    of this section).
------------------------------------------------------------------------

    (2) PW,OFF. If individual models of single-package 
systems or individual combinations (or ``tested combinations'') of split 
systems that are otherwise identical are offered with multiple options 
for off mode-related components, determine the represented value for the 
individual model/combination with the crankcase heater and controls that 
are the most consumptive. A manufacturer may also determine represented 
values for individual models/combinations with less consumptive off mode 
options; however, all such options must be identified with different 
model numbers for single-package systems or for outdoor units (in the 
case of split systems).
    (3) Refrigerants. (i) If a model of outdoor unit (used in a single-
split, multi-split, multi-circuit, multi-head mini-split, and/or outdoor 
unit with no

[[Page 147]]

match system) is distributed in commerce and approved for use with 
multiple refrigerants, a manufacturer must determine all represented 
values for that model using each refrigerant that can be used in an 
individual combination of the basic model (including outdoor units with 
no match or ``tested combinations''). This requirement may apply across 
the listed categories in the table in paragraph (a)(1) of this section. 
A refrigerant is considered approved for use if it is listed on the 
nameplate of the outdoor unit. If any of the refrigerants approved for 
use is HCFC-22 or has a 95 [deg]F midpoint saturation absolute pressure 
that is  18 percent of the 95 [deg]F saturation 
absolute pressure for HCFC-22, or if there are no refrigerants 
designated as approved for use, a manufacturer must determine 
represented values (including SEER, EER, HSPF, SEER2, EER2, HSPF2, 
PW,OFF, cooling capacity, and heating capacity, as 
applicable) for, at a minimum, an outdoor unit with no match. If a model 
of outdoor unit is not charged with a specified refrigerant from the 
point of manufacture or if the unit is shipped requiring the addition of 
more than two pounds of refrigerant to meet the charge required for 
testing per section 2.2.5 of appendix M or appendix M1 (unless either 
(a) the factory charge is equal to or greater than 70% of the outdoor 
unit internal volume times the liquid density of refrigerant at 95 
[deg]F or (b) an A2L refrigerant is approved for use and listed in the 
certification report), a manufacturer must determine represented values 
(including SEER, EER, HSPF, SEER2, EER2, HSPF2, PW,OFF, 
cooling capacity, and heating capacity, as applicable) for, at a 
minimum, an outdoor unit with no match.
    (ii) If a model is approved for use with multiple refrigerants, a 
manufacturer may make multiple separate representations for the 
performance of that model (all within the same individual combination or 
outdoor unit with no match) using the multiple approved refrigerants. In 
the alternative, manufacturers may certify the model (all within the 
same individual combination or outdoor unit with no match) with a single 
representation, provided that the represented value is no more efficient 
than its performance using the least-efficient refrigerant. If a 
manufacturer certifies a single model with multiple representations for 
the different approved refrigerants, it may use an AEDM to determine the 
represented values for all other refrigerants besides the refrigerant 
used for testing. A single representation made for multiple refrigerants 
may not include equipment in multiple categories or equipment 
subcategories listed in the table in paragraph (a)(1) of this section.
    (4) Limitations for represented values of individual combinations. 
The following paragraphs explains the limitations for represented values 
of individual combinations (or ``tested combinations'').
    (i) Regional. A basic model may only be certified as compliant with 
a regional standard if all individual combinations within that basic 
model meet the regional standard for which it is certified. A model of 
outdoor unit that is certified below a regional standard can only be 
rated and certified as compliant with a regional standard if the model 
of outdoor unit has a unique model number and has been certified as a 
different basic model for distribution in each region. An ICM cannot 
certify an individual combination with a rating that is compliant with a 
regional standard if the individual combination includes a model of 
outdoor unit that the OUM has certified with a rating that is not 
compliant with a regional standard. Conversely, an ICM cannot certify an 
individual combination with a rating that is not compliant with a 
regional standard if the individual combination includes a model of 
outdoor unit that an OUM has certified with a rating that is compliant 
with a regional standard.
    (ii) Multiple product classes. Models of outdoor units that are 
rated and distributed in individual combinations that span multiple 
product classes must be tested, rated, and certified pursuant to 
paragraph (a) of this section as compliant with the applicable standard 
for each product class. This includes multi-split systems, multi-circuit 
systems, and multi-head mini-split systems with a represented value for 
a mixed combination including

[[Page 148]]

both SDHV and either non-ducted or ducted indoor units.
    (5) Requirements. All represented values under paragraph (a) of this 
section must be based on testing in accordance with the requirements in 
paragraph (b) of this section or the application of an AEDM or other 
methodology as allowed in paragraph (c) of this section.
    (b) Units tested--(1) General. The general requirements of Sec. 
429.11 apply to central air conditioners and heat pumps; and
    (2) Individual model/combination selection for testing. (i) The 
table identifies the minimum testing requirements for each basic model 
that includes multiple individual models/combinations; if a basic model 
spans multiple categories or subcategories listed in the table, multiple 
testing requirements apply. For each basic model that includes only one 
individual model/combination, test that individual model/combination. 
For single-split-system non-space-constrained air conditioners and heat 
pumps, when testing is required in accordance with 10 CFR part 430, 
subpart B, appendix M1, these requirements do not apply until July 1, 
2024, provided that the manufacturer is certifying compliance of all 
basic models using an AEDM in accordance with paragraph (c)(1)(i)(B) of 
this section and paragraph (e)(2)(i)(A) of Sec. 429.70.

requirements of Sec. 429.70.
    (b) [Reserved]

[82 FR 1099, Jan. 4, 2017]



Sec. 429.70  Alternative methods for determining energy efficiency
and energy use.

    (a) General applicability of an AEDM. A manufacturer of covered 
products or covered equipment explicitly authorized to use an AEDM in 
Sec. Sec. 429.14 through 429.62 may not distribute any basic model of 
such equipment in commerce unless the manufacturer has determined the 
energy efficiency of the basic model, either from testing the basic 
model in conjunction with DOE's certification sampling plans and 
statistics or from applying an alternative method for determining energy 
efficiency or energy use (AEDM) to the basic model, in accordance with 
the requirements of this section. In instances where a manufacturer has 
tested a basic model, the manufacturer may not knowingly use an AEDM to 
overrate the efficiency (or underrate the consumption) of the model.
    (b) Testing. Testing for each covered product or covered equipment 
must be done in accordance with the sampling plan provisions established 
in Sec. 429.11 and the testing procedures in parts 430 and 431 of this 
chapter.
    (c) Alternative efficiency determination method (AEDM) for 
commercial HVAC (includes commercial warm air furnaces and commercial 
packaged boilers), WH, and refrigeration equipment--(1) Criteria an AEDM 
must satisfy. A manufacturer may not apply an AEDM to a basic model to 
determine its efficiency pursuant to this section unless:
    (i) The AEDM is derived from a mathematical model that estimates the 
energy efficiency or energy consumption characteristics of the basic 
model as measured by the applicable DOE test procedure;
    (ii) The AEDM is based on engineering or statistical analysis, 
computer simulation or modeling, or other analytic evaluation of 
performance data; and
    (iii) The manufacturer has validated the AEDM, in accordance with 
paragraph (c)(2) of this section with basic models that meet the current 
Federal energy conservation standards.
    (2) Validation of an AEDM. Before using an AEDM, the manufacturer 
must validate the AEDM's accuracy and reliability as follows:
    (i) The manufacturer must select at least the minimum number of 
basic models for each validation class specified in paragraph (c)(2)(iv) 
of this section to which the particular AEDM applies. Using the AEDM, 
calculate the energy use or efficiency for each of the selected basic 
models. Test a single unit of each selected basic model in accordance 
with paragraph (c)(2)(iii) of this section. Compare the results from the 
single unit test and the AEDM energy use or efficiency output according 
to paragraph (c)(2)(ii) of this section. The manufacturer is responsible 
for ensuring the accuracy and reliability of the AEDM.
    (ii) Individual model tolerances. (A) For those covered products 
with an energy-efficiency metric, the predicted efficiency for each 
model calculated by applying the AEDM may not be more than five percent 
greater than the efficiency determined from the corresponding test of 
the model.
    (B) For those covered products with an energy-consumption metric, 
the predicted energy consumption for each model, calculated by applying 
the AEDM, may not be more than five percent less than the energy 
consumption determined from the corresponding test of the model.

[[Page 231]]

    (C) For all covered products, the predicted energy efficiency or 
consumption for each model calculated by applying the AEDM must meet or 
exceed the applicable federal energy conservation performance standard.
    (D) An AEDM that is validated based on test results obtained from 
one or more field tests (pursuant to Sec. 431.86(c)) can only be used 
to certify the performance of basic models of commercial packaged 
boilers with a certified rated input greater than 5,000,000 Btu/h.
    (iii) Additional test unit requirements. (A) Each AEDM must be 
supported by test data obtained from physical tests of current models; 
and
    (B) Test results used to validate the AEDM must meet or exceed 
current, applicable Federal standards as specified in part 431 of this 
chapter; and
    (C) Each test must have been performed in accordance with the DOE 
test procedure specified in parts 430 or 431 of this chapter or test 
procedure waiver for which compliance is required at the time the basic 
model is distributed in commerce.
    (iv) Validation classes.

\1\ The minimum number of tests indicated above must be comprised of a
  transparent model, a solid model, a vertical model, a semi-vertical
  model, a horizontal model, and a service-over-the counter model, as
  applicable based on the equipment offering. However, manufacturers do
  not need to include all types of these models if it will increase the
  minimum number of tests that need to be conducted.

    (3) AEDM records retention requirements. If a manufacturer has used 
an AEDM to determine representative values pursuant to this section, the 
manufacturer must have available upon request for inspection by the 
Department records showing:
    (i) The AEDM, including the mathematical model, the engineering or 
statistical analysis, and/or computer simulation or modeling that is the 
basis of the AEDM;
    (ii) Product information, complete test data, AEDM calculations, and 
the statistical comparisons from the units tested that were used to 
validate the AEDM pursuant to paragraph (c)(2) of this section; and
    (iii) Product information and AEDM calculations for each basic model 
to which the AEDM has been applied.
    (4) Additional AEDM requirements. If requested by the Department and 
at DOE's discretion, the manufacturer must perform at least one of the 
following:
    (i) Conduct simulations before representatives of the Department to 
predict the performance of particular basic models of the product to 
which the AEDM was applied;
    (ii) Provide analyses of previous simulations conducted by the 
manufacturer; or
    (iii) Conduct certification testing of basic models selected by the 
Department.
    (5) AEDM verification testing. DOE may use the test data for a given 
individual model generated pursuant to Sec. 429.104 to verify the 
certified rating determined by an AEDM as long as the following process 
is followed:
    (i) Selection of units. DOE will obtain units for test from retail, 
where available. If units cannot be obtained from retail, DOE will 
request that a unit be provided by the manufacturer;
    (ii) Lab requirements. DOE will conduct testing at an independent, 
third-party testing facility of its choosing. In cases where no third-
party laboratory is capable of testing the equipment, it may be tested 
at a manufacturer's facility upon DOE's request.
    (iii) Manufacturer participation. (A) Except when testing variable 
refrigerant flow systems (which are governed by the rules found at Sec. 
431.96(f)), testing will be completed without a manufacturer 
representative on-site. In limited instances further described in 
paragraph (c)(5)(iii)(B) of this section, a manufacturer and DOE 
representative may be present to witness the test set-up.
    (B) A manufacturer's representative may request to be on-site to 
witness the test set-up if:
    (1) The installation manual for the basic model specifically 
requires it to be started only by a factory-trained installer; or
    (2) The manufacturer has elected, as part of the certification of 
that basic model, to have the opportunity to witness the test set-up. A 
manufacturer may elect to witness the test set-up for the initial 
verification test for no more than 10 percent of the manufacturer's 
basic models submitted for certification and rated with an AEDM per 
validation class specified in section (c)(2)(iv) of this paragraph. The 
10-percent limit applies to all of the eligible basic models submitted 
for certification by a given manufacturer no matter how many AEDMs a 
manufacturer has used to develop its ratings. The 10-percent limit is 
determined by first calculating 10 percent of the total number of basic 
models rated with an AEDM per validation class, and then truncating the 
resulting product. Manufacturers who have submitted fewer than 10 basic 
models rated with an AEDM for certification may elect to have the 
opportunity to witness the test set-up of one basic model. A 
manufacturer must identify the basic models

[[Page 233]]

it wishes to witness as part of its certification report(s) prior to the 
basic model being selected for verification testing.
    (3) In those instances in which a manufacturer has not provided the 
required information as specified in Sec. 429.12(b)(13) for a given 
basic model that has been rated and certified as compliant with the 
applicable standards, a manufacturer is precluded from witnessing the 
testing set up for that basic model.
    (C) A DOE representative will be present for the test set-up in all 
cases where a manufacturer representative requests to be on-site for the 
test set-up. The manufacturer's representative cannot communicate with a 
lab representative outside of the DOE representative's presence.
    (D) If DOE has obtained through retail channels a unit for test that 
meets either of the conditions in paragraph (c)(5)(iii)(B) of this 
section, DOE will notify the manufacturer that the basic model was 
selected for testing and that the manufacturer may have a representative 
present for the test set-up. If the manufacturer does not respond within 
five calendar days of receipt of that notification, the manufacturer 
waives the option to be present for test set-up, and DOE will proceed 
with the test set-up without a manufacturer's representative present.
    (E) If DOE has obtained directly from the manufacturer a unit for 
test that meets either of the conditions in paragraph (c)(5)(iii)(B) of 
this section, DOE will notify the manufacturer of the option to be 
present for the test set-up at the time the unit is purchased. DOE will 
specify the date (not less than five calendar days) by which the 
manufacturer must notify DOE whether a manufacturer's representative 
will be present. If the manufacturer does not notify DOE by the date 
specified, the manufacturer waives the option to be present for the test 
set-up, and DOE will proceed with the test set-up without a 
manufacturer's representative present.
    (F) DOE will review the certification submissions from the 
manufacturer that were on file as of the date DOE purchased a basic 
model (under paragraph (c)(5)(iii)(D) of this section) or the date DOE 
notifies the manufacturer that the basic model has been selected for 
testing (under paragraph (c)(5)(iii)(E) of this section) to determine if 
the manufacturer has indicated that it intends to witness the test set-
up of the selected basic model. DOE will also verify that the 
manufacturer has not exceeded the allowable limit of witness testing 
selections as specified in paragraph (c)(5)(iii)(B)(2) of this section. 
If DOE discovers that the manufacturer exceeded the limits specified in 
paragraph (c)(5)(iii)(B)(2), DOE will notify the manufacturer of this 
fact and deny its request to be present for the test set-up of the 
selected basic model. The manufacturer must update its certification 
submission to ensure it has not exceeded the allowable limit of witness 
testing selections as specified in paragraph (c)(5)(iii)(B)(2) to be 
present at set-up for future selections. At this time DOE will also 
review the supplemental PDF submission(s) for the selected basic model 
to determine that all necessary information has been provided to the 
Department.
    (G) If DOE determines, pursuant to paragraph (c)(5)(ii) of this 
section, that the model should be tested at the manufacturer's facility, 
a DOE representative will be present on site to observe the test set-up 
and testing with the manufacturer's representative. All testing will be 
conducted at DOE's direction, which may include DOE-contracted personnel 
from a third-party lab, as well as the manufacturer's technicians.
    (H) As further explained in paragraph (c)(5)(v)(B) of this section, 
if a manufacturer's representative is present for the initial test set-
up for any reason, the manufacturer forfeits any opportunity to request 
a retest of the basic model. Furthermore, if the manufacturer requests 
to be on-site for test set-up pursuant to paragraph (c)(5)(iii)(B) of 
this section but is not present on site, the manufacturer forfeits any 
opportunity to request a retest of the basic model.
    (iv) Testing. At no time during verification testing may the lab and 
the manufacturer communicate without DOE authorization. All verification 
testing will be conducted in accordance

[[Page 234]]

with the applicable DOE test procedure, as well as each of the following 
to the extent that they apply:
    (A) Any active test procedure waivers that have been granted for the 
basic model;
    (B) Any test procedure guidance that has been issued by DOE;
    (C) The installation and operations manual that is shipped with the 
unit;
    (D) Any additional information that was provided by the manufacturer 
at the time of certification (prior to DOE obtaining the unit for test); 
and
    (E) If during test set-up or testing, the lab indicates to DOE that 
it needs additional information regarding a given basic model in order 
to test in accordance with the applicable DOE test procedure, DOE may 
organize a meeting between DOE, the manufacturer and the lab to provide 
such information.
    (v) Failure to meet certified rating. If a model tests worse than 
its certified rating by an amount exceeding the tolerance prescribed in 
paragraph (c)(5)(vi) of this section, DOE will notify the manufacturer. 
DOE will provide the manufacturer with all documentation related to the 
test set up, test conditions, and test results for the unit. Within the 
timeframe allotted by DOE, the manufacturer may then:
    (A) Present all claims regarding testing validity; and
    (B) If the manufacturer was not on site for the initial test set-up, 
request a retest of the previously tested unit with manufacturer and DOE 
representatives on-site for the test set-up. DOE will not conduct the 
retest using a different unit of the same basic model unless DOE and the 
manufacturer determine it is necessary based on the test results, claims 
presented, and DOE regulations.
    (vi) Tolerances. (A) For consumption metrics, the result from a DOE 
verification test must be less than or equal to the certified rating x 
(1 + the applicable tolerance).
    (B) For efficiency metrics, the result from a DOE verification test 
must be greater than or equal to the certified rating x (1 - the 
applicable tolerance).

    (vii) Invalid rating. If, following discussions with the 
manufacturer and a retest where applicable, DOE determines that the 
verification testing was

[[Page 235]]

conducted appropriately in accordance with the DOE test procedure, DOE 
will issue a determination that the rating for the model is invalid. The 
manufacturer must elect, within 15 days, one of the following to be 
completed in a time frame specified by DOE, which is never to exceed 180 
days:
    (A) Re-rate and re-certify the model based on DOE's test data alone; 
or
    (B) Discontinue the model through the certification process; or
    (C) Conduct additional testing and re-rate and re-certify the basic 
model based on all test data collected, including DOE's test data.
    (viii) AEDM use. (A) If DOE has determined that a manufacturer made 
invalid ratings on two or more models rated using the same AEDM within a 
24 month period, the manufacturer must take the action listed in the 
table corresponding to the number of invalid certified ratings. The 
twenty-four month period begins with a DOE determination that a rating 
is invalid through the process outlined above. Additional invalid 
ratings apply for the purposes of determining the appropriate 
consequences if the subsequent determination(s) is based on selection of 
a unit for testing within the twenty-four month period (i.e., subsequent 
determinations need not be made within 24 months).

                                 from testing to validate that AEDM
                                 within the validation classes to which
                                 it is applied.\1\ Adjust the ratings as
                                 appropriate.

                                 Note, the tests required under this
                                 paragraph (c)(5)(viii) must be
                                 performed on different models than the
                                 original tests required under paragraph
                                 (c)(2) of this section.
6.............................  Conduct the minimum number of validation
                                 tests for the validation classes to
                                 which the AEDM is applied at a third-
                                 part test facility; And
                                Conduct addition testing, which is equal
                                 to \1/2\ the minimum number of
                                 validation tests for the validation
                                 classes to which the AEDM is applied ,
                                 at either the manufacturer's facility
                                 or a third-party test facility, at the
                                 manufacturer's discretion.
                                Note, the tests required under this
                                 paragraph (c)(5)(viii) must be
                                 performed on different models than the
                                 original tests performed under
                                 paragraph (c)(2) of this section.
 = 8...............  Manufacturer has lost privilege to use
                                 AEDM. All ratings for models within the
                                 validation classes to which the AEDM
                                 applied should be rated via testing.
                                 Distribution cannot continue until
                                 certification(s) are corrected to
                                 reflect actual test data.
------------------------------------------------------------------------
\1\ A manufacturer may discuss with DOE's Office of Enforcement whether
  existing test data on different basic models within the validation
  classes to which that specific AEDM was applied may be used to meet
  this requirement.
\2\ The ``same AEDM'' means a computer simulation or mathematical model
  that is identified by the manufacturer at the time of certification as
  having been used to rate a model or group of models.
\3\ The twenty-four month period begins with a DOE determination that a
  rating is invalid through the process outlined above. Additional
  invalid ratings apply for the purposes of determining the appropriate
  consequences if the subsequent determination(s) is based on testing of
  a unit that was selected for testing within the twenty-four month
  period (i.e., subsequent determinations need not be made within 24
  months).

    (B) If, as a result of eight or more invalid ratings, a manufacturer 
has lost the privilege of using an AEDM for rating, the manufacturer may 
regain the ability to use an AEDM by:
    (1) Investigating and identifying cause(s) for failures;
    (2) Taking corrective action to address cause(s);
    (3) Performing six new tests per validation class, a minimum of two 
of which must be performed by an independent, third-party laboratory to 
validate the AEDM; and
    (4) Obtaining DOE authorization to resume use of the AEDM.
    (d) Alternative efficiency determination method for distribution 
transformers--A manufacturer may use an AEDM to determine the efficiency 
of one or more of its untested basic models only if it determines the 
efficiency of at least five of its other basic models (selected in 
accordance with paragraph (d)(3) of this section) through actual 
testing.
    (1) Criteria an AEDM must satisfy.
    (i) The AEDM has been derived from a mathematical model that 
represents the electrical characteristics of that basic model;
    (ii) The AEDM is based on engineering and statistical analysis, 
computer

[[Page 236]]

simulation or modeling, or other analytic evaluation of performance 
data; and
    (iii) The manufacturer has substantiated the AEDM, in accordance 
with paragraph (d)(2) of this section, by applying it to, and testing, 
at least five other basic models of the same type, i.e., low-voltage 
dry-type distribution transformers, medium-voltage dry-type distribution 
transformers, or liquid-immersed distribution transformers.
    (2) Substantiation of an AEDM. Before using an AEDM, the 
manufacturer must substantiate the AEDM's accuracy and reliability as 
follows:
    (i) Apply the AEDM to at least five of the manufacturer's basic 
models that have been selected for testing in accordance with paragraph 
(d)(3) of this section, and calculate the power loss for each of these 
basic models;
    (ii) Test at least five units of each of these basic models in 
accordance with the applicable test procedure and Sec. 429.47, and 
determine the power loss for each of these basic models;
    (iii) The predicted total power loss for each of these basic models, 
calculated by applying the AEDM pursuant to paragraph (d)(2)(i) of this 
section, must be within plus or minus five percent of the mean total 
power loss determined from the testing of that basic model pursuant to 
paragraph (d)(2)(ii) of this section; and
    (iv) Calculate for each of these basic models the percentage that 
its power loss calculated pursuant to paragraph (d)(2)(i) of this 
section is of its power loss determined from testing pursuant to 
paragraph (d)(2)(ii) of this section, compute the average of these 
percentages, and that calculated average power loss, expressed as a 
percentage of the average power loss determined from testing, must be no 
less than 97 percent and no greater than 103 percent.
    (3) Additional testing requirements. (i) A manufacturer must select 
basic models for testing in accordance with the following criteria:
    (A) Two of the basic models must be among the five basic models with 
the highest unit volumes of production by the manufacturer in the prior 
year, or during the prior 12-calendar-month period beginning in 2003,\1\ 
whichever is later;
---------------------------------------------------------------------------

    \1\ When identifying these five basic models, any basic model that 
does not comply with Federal energy conservation standards for 
distribution transformers that may be in effect shall be excluded from 
consideration.
---------------------------------------------------------------------------

    (B) No two basic models should have the same combination of power 
and voltage ratings; and
    (C) At least one basic model should be single-phase and at least one 
should be three-phase.
    (ii) In any instance where it is impossible for a manufacturer to 
select basic models for testing in accordance with all of these 
criteria, the criteria shall be given priority in the order in which 
they are listed. Within the limits imposed by the criteria, basic models 
shall be selected randomly.
    (4) Subsequent verification of an AEDM. (i) Each manufacturer that 
has used an AEDM under this section shall have available for inspection 
by the Department of Energy records showing:
    (A) The method or methods used;
    (B) The mathematical model, the engineering or statistical analysis, 
computer simulation or modeling, and other analytic evaluation of 
performance data on which the AEDM is based;
    (C) Complete test data, product information, and related information 
that the manufacturer has generated or acquired pursuant to paragraph 
(d)(4) of this section; and
    (D) The calculations used to determine the efficiency and total 
power losses of each basic model to which the AEDM was applied.
    (ii) If requested by the Department, the manufacturer must perform 
at least one of the following:
    (A) Conduct simulations to predict the performance of particular 
basic models of distribution transformers specified by the Department;
    (B) Provide analyses of previous simulations conducted by the 
manufacturer;
    (C) Conduct sample testing of basic models selected by the 
Department; or
    (D) Conduct a combination of these.
    (e) Alternate Efficiency Determination Method (AEDM) for central air 
conditioners and heat pumps. This paragraph (e) sets forth the 
requirements for a manufacturer to use an AEDM to rate

[[Page 237]]

central air conditioners and heat pumps.
    (1) Criteria an AEDM must satisfy. A manufacturer may not apply an 
AEDM to an individual model/combination to determine its represented 
values (SEER, EER, HSPF, SEER2, EER2, HSPF2, and/or PW,OFF) 
pursuant to this section unless authorized pursuant to Sec. 429.16(d) 
and:
    (i) The AEDM is derived from a mathematical model that estimates the 
energy efficiency or energy consumption characteristics of the 
individual model or combination (SEER, EER, HSPF, SEER2, EER2, HSPF2, 
and/or PW,OFF) as measured by the applicable DOE test 
procedure; and
    (ii) The manufacturer has validated the AEDM in accordance with 
paragraph (e)(2) of this section.
    (2) Validation of an AEDM. Before using an AEDM, the manufacturer 
must validate the AEDM's accuracy and reliability as follows:
    (i) Follow paragraph (e)(2)(i)(A) of this section for requirements 
on minimum testing. Follow paragraph (e)(2)(i)(B) of this section for 
requirements on ensuring the accuracy and reliability of the AEDM.
    (A) Minimum testing. (1) For non-space-constrained single-split 
system air conditioners and heat pumps rated based on testing in 
accordance with appendix M to subpart B of part 430, the manufacturer 
must test each basic model as required under Sec. 429.16(b)(2). Until 
July 1, 2024, for non-space-constrained single-split-system air 
conditioners and heat pumps rated based on testing in accordance with 
appendix M1 to subpart B of part 430, the manufacturer must test a 
single-unit sample from 20 percent of the basic models distributed in 
commerce to validate the AEDM. On or after July 1, 2024, for non-space-
constrained single-split-system air conditioners and heat pumps rated 
based on testing in accordance with appendix M1 to subpart B of part 
430, the manufacturer must complete testing of each basic model as 
required under Sec. 429.16(b)(2).
    (2) For other than non-space-constrained single-split-system air 
conditioners and heat pumps, the manufacturer must test each basic model 
as required under Sec. 429.16(b)(2).
    (B) Using the AEDM, calculate the energy use or efficiency for each 
of the tested individual models/combinations within each basic model. 
Compare the represented value based on testing and the AEDM energy use 
or efficiency output according to paragraph (e)(2)(ii) of this section. 
The manufacturer is responsible for ensuring the accuracy and 
reliability of the AEDM and that their representations are appropriate 
and the models being distributed in commerce meet the applicable 
standards, regardless of the amount of testing required in paragraphs 
(e)(2)(i)(A) and (e)(2)(i)(B) of this section.
    (ii) Individual model/combination tolerances. This paragraph 
(e)(2)(ii) provides the tolerances applicable to individual models/
combinations rated using an AEDM.
    (A) The predicted represented values for each individual model/
combination calculated by applying the AEDM may not be more than four 
percent greater (for measures of efficiency) or less (for measures of 
consumption) than the values determined from the corresponding test of 
the individual model/combination.
    (B) The predicted energy efficiency or consumption for each 
individual model/combination calculated by applying the AEDM must meet 
or exceed the applicable federal energy conservation standard.
    (iii) Additional test unit requirements. (A) Each AEDM must be 
supported by test data obtained from physical tests of current 
individual models/combinations; and
    (B) Test results used to validate the AEDM must meet or exceed 
current, applicable Federal standards as specified in part 430 of this 
chapter; and
    (C) Each test must have been performed in accordance with the 
applicable DOE test procedure with which compliance is required at the 
time the individual models/combinations used for validation are 
distributed in commerce.
    (3) AEDM records retention requirements. If a manufacturer has used 
an AEDM to determine representative values pursuant to this section, the 
manufacturer must have available upon request for inspection by the 
Department records showing:

[[Page 238]]

    (i) The AEDM, including the mathematical model, the engineering or 
statistical analysis, and/or computer simulation or modeling that is the 
basis of the AEDM;
    (ii) Product information, complete test data, AEDM calculations, and 
the statistical comparisons from the units tested that were used to 
validate the AEDM pursuant to paragraph (e)(2) of this section; and
    (iii) Product information and AEDM calculations for each individual 
model/combination to which the AEDM has been applied.
    (4) Additional AEDM requirements. If requested by the Department, 
the manufacturer must:
    (i) Conduct simulations before representatives of the Department to 
predict the performance of particular individual models/combinations;
    (ii) Provide analyses of previous simulations conducted by the 
manufacturer; and/or
    (iii) Conduct certification testing of individual models or 
combinations selected by the Department.
    (5) AEDM verification testing. DOE may use the test data for a given 
individual model/combination generated pursuant to Sec. 429.104 to 
verify the represented value determined by an AEDM as long as the 
following process is followed:
    (i) Selection of units. DOE will obtain one or more units for test 
from retail, if available. If units cannot be obtained from retail, DOE 
will request that a unit be provided by the manufacturer;
    (ii) Lab requirements. DOE will conduct testing at an independent, 
third-party testing facility of its choosing. In cases where no third-
party laboratory is capable of testing the equipment, testing may be 
conducted at a manufacturer's facility upon DOE's request.
    (iii) Testing. At no time during verification testing may the lab 
and the manufacturer communicate without DOE authorization. If during 
test set-up or testing, the lab indicates to DOE that it needs 
additional information regarding a given individual model or combination 
in order to test in accordance with the applicable DOE test procedure, 
DOE may organize a meeting between DOE, the manufacturer and the lab to 
provide such information.
    (iv) Failure to meet certified value. If an individual model/
combination tests worse than its certified value (i.e., lower than the 
certified efficiency value or higher than the certified consumption 
value) by more than 5 percent, or the test results in cooling capacity 
that is lower than its certified cooling capacity, DOE will notify the 
manufacturer. DOE will provide the manufacturer with all documentation 
related to the test set up, test conditions, and test results for the 
unit. Within the timeframe allotted by DOE, the manufacturer may present 
any and all claims regarding testing validity.
    (v) Tolerances. This paragraph specifies the tolerances DOE will 
permit when conducting verification testing.
    (A) For consumption metrics, the result from a DOE verification test 
must be less than or equal to 1.05 multiplied by the certified 
represented value.
    (B) For efficiency metrics, the result from a DOE verification test 
must be greater than or equal to 0.95 multiplied by the certified 
represented value.
    (vi) Invalid represented value. If, following discussions with the 
manufacturer and a retest where applicable, DOE determines that the 
verification testing was conducted appropriately in accordance with the 
DOE test procedure, DOE will issue a determination that the represented 
values for the basic model are invalid. The manufacturer must conduct 
additional testing and re-rate and re-certify the individual models/
combinations within the basic model that were rated using the AEDM based 
on all test data collected, including DOE's test data.
    (vii) AEDM use. This paragraph (e)(5)(vii) specifies when a 
manufacturer's use of an AEDM may be restricted due to prior invalid 
represented values.
    (A) If DOE has determined that a manufacturer made invalid 
represented values on individual models/combinations within two or more 
basic models rated using the manufacturer's AEDM within a 24 month 
period, the manufacturer must test the least efficient and most 
efficient individual model/combination within each basic model in 
addition to the individual model/combination specified in Sec. 
429.16(b)(2). The

[[Page 239]]

twenty-four month period begins with a DOE determination that a 
represented value is invalid through the process outlined above.
    (B) If DOE has determined that a manufacturer made invalid 
represented values on more than four basic models rated using the 
manufacturer's AEDM within a 24-month period, the manufacturer may no 
longer use an AEDM.
    (C) If a manufacturer has lost the privilege of using an AEDM, the 
manufacturer may regain the ability to use an AEDM by:
    (1) Investigating and identifying cause(s) for failures;
    (2) Taking corrective action to address cause(s);
    (3) Performing six new tests per basic model, a minimum of two of 
which must be performed by an independent, third-party laboratory from 
units obtained from retail to validate the AEDM; and
    (4) Obtaining DOE authorization to resume use of an AEDM.
    (f) Alternative efficiency determination method (AEDM) for walk-in 
refrigeration equipment--
    (1) Criteria an AEDM must satisfy. A manufacturer may not apply an 
AEDM to a basic model to determine its efficiency pursuant to this 
section unless:
    (i) The AEDM is derived from a mathematical model that estimates the 
energy efficiency or energy consumption characteristics of the basic 
model as measured by the applicable DOE test procedure;
    (ii) The AEDM is based on engineering or statistical analysis, 
computer simulation or modeling, or other analytical evaluation of 
performance data; and
    (iii) The manufacturer has validated the AEDM, in accordance with 
paragraph (f)(2) of this section.
    (2) Validation of an AEDM. Before using an AEDM, the manufacturer 
must validate the AEDM's accuracy and reliability as follows:
    (i) The manufacturer must select at least the minimum number of 
basic models for each validation class specified in paragraph (f)(2)(iv) 
of this section to which the particular AEDM applies. Test a single unit 
of each basic model in accordance with paragraph (f)(2)(iii) of this 
section. Using the AEDM, calculate the energy use or energy efficiency 
for each of the selected basic models. Compare the results from the 
single unit test and the AEDM output according to paragraph (f)(2)(ii) 
of this section. The manufacturer is responsible for ensuring the 
accuracy and repeatability of the AEDM.
    (ii) Individual model tolerances. (A) The predicted efficiency for 
each model calculated by applying the AEDM may not be more than five 
percent greater than the efficiency determined from the corresponding 
test of the model.
    (B) The predicted energy efficiency for each model calculated by 
applying the AEDM must meet or exceed the applicable federal energy 
conservation standard.
    (iii) Additional test unit requirements. (A) Each AEDM must be 
supported by test data obtained from physical tests of current models; 
and
    (B) Test results used to validate the AEDM must meet or exceed 
current, applicable Federal standards as specified in part 431 of this 
chapter;
    (C) Each test must have been performed in accordance with the 
applicable DOE test procedure with which compliance is required at the 
time the basic model is distributed in commerce; and
    (D) For rating WICF refrigeration system components, an AEDM may not 
simulate or model portions of the system that are not required to be 
tested by the DOE test procedure. That is, if the test results used to 
validate the AEDM are for either a unit cooler only or a condensing unit 
only, the AEDM must estimate the system rating using the nominal values 
specified in the DOE test procedure for the other part of the 
refrigeration system.
    (iv) WICF refrigeration validation classes.

    (3) AEDM records retention requirements. If a manufacturer has used 
an AEDM to determine representative values pursuant to this section, the 
manufacturer must have available upon request for inspection by the 
Department records showing:
    (i) The AEDM, including the mathematical model, the engineering or 
statistical analysis, and/or computer simulation or modeling that is the 
basis of the AEDM;
    (ii) Equipment information, complete test data, AEDM calculations, 
and the statistical comparisons from the units tested that were used to 
validate the AEDM pursuant to paragraph (f)(2) of this section; and
    (iii) Equipment information and AEDM calculations for each basic 
model to which the AEDM has been applied.
    (4) Additional AEDM requirements. If requested by the Department the 
manufacturer must perform at least one of the following:
    (i) Conduct simulations before representatives of the Department to 
predict the performance of particular basic models of the product to 
which the AEDM was applied;
    (ii) Provide analyses of previous simulations conducted by the 
manufacturer; or
    (iii) Conduct certification testing of basic models selected by the 
Department.
    (5) AEDM verification testing. DOE may use the test data for a given 
individual model generated pursuant to Sec. 429.104 to verify the 
certified rating determined by an AEDM as long as the following process 
is followed:
    (i) Selection of units. DOE will obtain units for test from retail, 
where available. If units cannot be obtained from retail, DOE will 
request that a unit be provided by the manufacturer.
    (ii) Lab requirements. DOE will conduct testing at an independent, 
third-party testing facility of its choosing. In cases where no third-
party laboratory is capable of testing the equipment, it may be tested 
at a manufacturer's facility upon DOE's request.
    (iii) Manufacturer participation. Testing will be performed without 
manufacturer representatives on-site.
    (iv) Testing. All verification testing will be conducted in 
accordance with the applicable DOE test procedure, as well as each of 
the following to the extent that they apply:
    (A) Any active test procedure waivers that have been granted for the 
basic model;
    (B) Any test procedure guidance that has been issued by DOE;
    (C) If during test set-up or testing, the lab indicates to DOE that 
it needs additional information regarding a given basic model in order 
to test in accordance with the applicable DOE test procedure, DOE may 
organize a

[[Page 241]]

meeting between DOE, the manufacturer and the lab to provide such 
information.
    (D) At no time during the process may the lab communicate directly 
with the manufacturer without DOE present.
    (v) Failure to meet certified rating. If a model tests worse than 
its certified rating by an amount exceeding the tolerance prescribed in 
paragraph (f)(5)(vi) of this section, DOE will notify the manufacturer. 
DOE will provide the manufacturer with all documentation related to the 
test set up, test conditions, and test results for the unit. Within the 
timeframe allotted by DOE, the manufacturer may then present all claims 
regarding testing validity.
    (vi) Tolerances. for efficiency metrics, the result from a DOE 
verification test must be greater than or equal to the certified rating 
x (1 - the applicable tolerance).

    (vii) Invalid rating. If, following discussions with the 
manufacturer and a retest where applicable, DOE determines that the 
testing was conducted appropriately in accordance with the DOE test 
procedure, the rating for the model will be considered invalid. Pursuant 
to 10 CFR 429.13(b), DOE may require a manufacturer to conduct 
additional testing as a remedial measure.
    (g) Alternative determination of ratings for untested basic models 
of residential water heaters and residential-duty commercial water 
heaters. For models of water heaters that differ only in fuel type or 
power input, ratings for untested basic models may be established in 
accordance with the following procedures in lieu of testing. This method 
allows only for the use of ratings identical to those of a tested basic 
model as provided below; simulations or other modeling predictions for 
ratings of the uniform energy factor, volume, first-hour rating, or 
maximum gallons per minute (GPM) are not permitted.
    (1) Gas Water Heaters. For untested basic models of gas-fired water 
heaters that differ from tested basic models only in whether the basic 
models use natural gas or propane gas, the represented value of uniform 
energy factor, first-hour rating, and maximum gallons per minute for an 
untested basic model is the same as that for a tested basic model, as 
long as the input ratings of the tested and untested basic models are 
within 10%, that is:
[GRAPHIC] [TIFF OMITTED] TR11JY14.066

    (2) Electric Storage Water Heaters. Rate an untested basic model of 
an electric storage type water heater using the first-hour rating and 
the uniform energy factor obtained from a tested basic model as a basis 
for ratings of basic models with other input ratings, provided that 
certain conditions are met:
    (i) For an untested basic model, the represented value of the first-
hour rating and the uniform energy factor is the same as that of a 
tested basic model, provided that each heating element of the untested 
basic model is rated at or above the input rating for the corresponding 
heating element of the tested basic model.
    (ii) For an untested basic model having any heating element with an 
input rating that is lower than that of the corresponding heating 
element in the tested basic model, the represented value of the first-
hour rating and the uniform energy factor is the same as that of a 
tested basic model, provided that the first-hour rating for the untested 
basic model results in the same draw pattern specified in Table I of 
appendix E for the simulated-use test as was applied to the tested basic 
model. To establish whether this condition is met, determine the first-
hour ratings for the tested and the untested basic models in accordance 
with the procedure described in section 5.3.3 of 10 CFR

[[Page 242]]

part 430, subpart B, appendix E, then compare the appropriate draw 
pattern specified in Table I of appendix E for the first-hour rating of 
the tested basic model with that for the untested basic model. If this 
condition is not met, then the untested basic model must be tested and 
the appropriate sampling provisions applied to determine its uniform 
energy factor in accordance with appendix E and this part.
    (h) Alternative efficiency determination method (AEDM) for 
compressors--(1) Criteria an AEDM must satisfy. A manufacturer may not 
apply an AEDM to a basic model to determine its efficiency pursuant to 
this section, unless:
    (i) The AEDM is derived from a mathematical model that estimates the 
energy efficiency or energy consumption characteristics of the basic 
model as measured by the applicable DOE test procedure;
    (ii) The AEDM is based on engineering or statistical analysis, 
computer simulation or modeling, or other analytic evaluation of 
performance data; and
    (iii) The manufacturer has validated the AEDM, in accordance with 
paragraph (h)(2) of this section.
    (2) Validation of an AEDM. Before using an AEDM, the manufacturer 
must validate the AEDM's accuracy and reliability as follows:
    (i) AEDM overview. The manufacturer must select at least the minimum 
number of basic models for each validation class specified in paragraph 
(h)(2)(iv) of this section to which the particular AEDM applies. Using 
the AEDM, calculate the energy use or energy efficiency for each of the 
selected basic models. Test each basic model and determine the 
represented value(s) in accordance with Sec. 429.63(a). Compare the 
results from the testing and the AEDM output according to paragraph 
(h)(2)(ii) of this section. The manufacturer is responsible for ensuring 
the accuracy and repeatability of the AEDM.
    (ii) AEDM basic model tolerances. (A) The predicted representative 
values for each basic model calculated by applying the AEDM may not be 
more than five percent greater (for measures of efficiency) or less (for 
measures of consumption) than the represented values determined from the 
corresponding test of the model.
    (B) The predicted package isentropic efficiency for each basic model 
calculated by applying the AEDM must meet or exceed the applicable 
federal energy conservation standard.
    (iii) Additional test unit requirements. (A) Each AEDM must be 
supported by test data obtained from physical tests of current models; 
and
    (B) Test results used to validate the AEDM must meet or exceed 
current, applicable Federal standards as specified in part 431 of this 
chapter; and
    (C) Each test must have been performed in accordance with the 
applicable DOE test procedure with which compliance is required at the 
time the basic models used for validation are distributed in commerce.
    (iv) Compressor validation classes.

    (3) AEDM Records Retention Requirements. If a manufacturer has used 
an AEDM to determine representative values pursuant to this section, the 
manufacturer must have available upon request for inspection by the 
Department records showing:
    (i) The AEDM, including the mathematical model, the engineering or 
statistical analysis, and/or computer simulation or modeling that is the 
basis of the AEDM;
    (ii) Equipment information, complete test data, AEDM calculations, 
and the statistical comparisons from the units tested that were used to 
validate the AEDM pursuant to paragraph (h)(2) of this section; and
    (iii) Equipment information and AEDM calculations for each basic 
model to which the AEDM was applied.
    (4) Additional AEDM requirements. If requested by the Department, 
the manufacturer must:
    (i) Conduct simulations before representatives of the Department to 
predict the performance of particular basic models of the equipment to 
which the AEDM was applied;

[[Page 243]]

    (ii) Provide analyses of previous simulations conducted by the 
manufacturer; and/or
    (iii) Conduct certification testing of basic models selected by the 
Department.

Sec. 429.71  Maintenance of records.

    (a) The manufacturer of any covered product or covered equipment 
shall establish, maintain, and retain the records of certification 
reports, of the underlying test data for all certification testing, and 
of any other testing conducted to satisfy the requirements of this part, 
part 430, and part 431. Any manufacturer who chooses to use an 
alternative method for determining energy efficiency or energy use in 
accordance with Sec. 429.70 must retain the records required by that 
section, any other records of any testing performed to support the use 
of the alternative method, and any certifications required by that 
section, on file for review by DOE for two years following the 
discontinuance of all models or combinations whose ratings were based on 
the alternative method.
    (b) Such records shall be organized and indexed in a fashion that 
makes them readily accessible for review by DOE upon request.
    (c) The records shall be retained by the manufacturer for a period 
of two years from the date that the manufacturer or third party 
submitter has notified DOE that the model has been discontinued in 
commerce.
    (d) When considering if a pump is subject to energy conservation 
standards under part 431 of this chapter, DOE may need to determine if a 
pump was designed and constructed to the requirements set forth in 
Military Specifications: MIL-P-17639F, MIL-P-17881D, MIL-P-17840C, MIL-
P-18682D, or MIL-P-18472G. In this case, a manufacturer must provide DOE 
with copies of the original design and test data that were submitted to 
appropriate design review agencies, as required by MIL-P-17639F, MIL-P-
17881D, MIL-P-17840C, MIL-P-18682D, or MIL-P-18472G. Military

Sec. 429.72  Alternative methods for determining non-energy ratings.

    (a) General. Where Sec. 429.14 through Sec. 429.562 authorize the 
use of an alternative method for determining a physical or operating 
characteristic other than the energy consumption or efficiency, such 
characteristics must be determined either by testing in accordance with 
the applicable test procedure and applying the specified sampling plan 
provisions established in those sections or as described in the 
appropriate product-specific paragraph below. In all cases, the 
computer-aided design (CAD) models, measurements, and calculations used 
to determine the rating for the physical or operating characteristic 
shall be retained as part of the test records underlying the 
certification of the basic model in accordance with Sec. 429.71.
    (b) Testing. [Reserved]
    (c) Residential refrigerators, refrigerator-freezers, and freezers. 
The total refrigerated volume of a basic model of refrigerator, 
refrigerator-freezer, or freezer may be determined by performing a 
calculation of the volume based upon computer-aided design (CAD) models 
of the basic model in lieu of physical measurements of a production unit 
of the basic model. Any value of total refrigerated volume of a basic 
model reported to DOE in a certification of compliance in accordance 
with Sec. 429.14(b)(2) must be calculated using the CAD-derived 
volume(s) and the applicable provisions in the test procedures in 10 CFR 
part 430 for measuring volume, and must be within two percent, or 0.5 
cubic feet (0.2 cubic feet for compact products), whichever is greater, 
of the volume of a production unit of the basic model measured in 
accordance with the applicable test procedure in 10 CFR part 430.
    (d) Miscellaneous refrigeration products. The total refrigerated 
volume of a miscellaneous refrigeration product

[[Page 244]]

basic model may be determined by performing a calculation of the volume 
based upon computer-aided design (CAD) models of the basic model in lieu 
of physical measurements of a production unit of the basic model. Any 
value of total adjusted volume and value of total refrigerated volume of 
a basic model reported to DOE in a certification of compliance in 
accordance with Sec. 429.61(b)(2) must be calculated using the CAD-
derived volume(s) and the applicable provisions in the test procedures 
in part 430 of this chapter for measuring volume. The calculated value 
must be within two percent, or 0.5 cubic feet (0.2 cubic feet for 
products with total refrigerated volume less than 7.75 cubic feet (220 
liters)), whichever is greater, of the volume of a production unit of 
the basic model measured in accordance with the applicable test 
procedure in part 430 of this chapter.
    (e) Commercial gas-fired and oil-fired instantaneous water heaters 
and hot water supply boilers. The storage volume of a commercial gas-
fired or oil-fired instantaneous water heater or a commercial gas-fired 
or oil-fired hot water supply boiler basic model may be determined by 
performing a calculation of the stored water volume based upon design 
drawings (including computer-aided design (CAD) models) or physical 
dimensions of the basic model. Any value of storage volume of a basic 
model reported to DOE in a certification of compliance in accordance 
with Sec. 429.44(c)(2)(iv) and (v) must be calculated using the design 
drawings or physical dimensions, or measured as per the applicable 
provisions in the test procedures in 10 CFR 431.106. The storage volume 
determination must include all water contained within the water heater 
from the inlet connection to the outlet connection(s). The storage 
volume of water contained in the water heater must then be computed in 
gallons.

    DOE may, at any time, test a basic model to assess whether the basic 
model is in compliance with the applicable energy conservation 
standard(s).



Sec. 429.106  Investigation of compliance.

    (a) DOE may initiate an investigation that a basic model may not be 
compliant with an applicable conservation standard, certification 
requirement or other regulation at any time.
    (b) DOE may, at any time, request any information relevant to 
determining compliance with any requirement under parts 429, 430 and 
431, including the data underlying certification of a basic model. Such 
data may be used by DOE to make a determination of compliance or 
noncompliance with an applicable standard.



Sec. 429.110  Enforcement testing.

    (a) General provisions. (1) If DOE has reason to believe that a 
basic model is not in compliance it may test for enforcement.
    (2) DOE will select and test units pursuant to paragraphs (c) and 
(e) of this section.
    (3) Testing will be conducted at a laboratory accredited to the 
International Organization for Standardization (ISO)/International 
Electrotechnical Commission (IEC), ``General requirements for the 
competence of testing and calibration laboratories,'' ISO/IEC 
17025:2005(E) (incorporated by reference; see Sec. 429.4). If testing 
cannot be completed at an independent laboratory, DOE, at its 
discretion, may allow enforcement testing at a manufacturer's 
laboratory, so long as the lab is accredited to ISO/IEC 17025:2005(E) 
and DOE representatives witness the testing. In addition, for commercial 
packaged boilers with rated input greater than 5,000,000 Btu/h, DOE, at 
its discretion, may allow enforcement testing of a commissioned 
commercial packaged boiler in the location in which it was commissioned 
for use, pursuant to the test provisions at Sec. 431.86(c) of this 
chapter, for which accreditation to ISO/IEC 17025:2005(E) would not be 
required.
    (b) Test notice. (1) To obtain units for enforcement testing to 
determine compliance with an applicable standard, DOE will issue a test 
notice addressed to the manufacturer in accordance with the following 
requirements:
    (i) DOE will send the test notice to the manufacturer's certifying 
official or other company official.
    (ii) The test notice will specify the basic model that will be 
selected for testing, the method of selecting the test sample, the 
maximum size of the sample and the size of the initial test sample, the 
dates at which testing is scheduled to be started and completed, and the 
facility at which testing will be conducted. The test notice may also 
provide for situations in which the selected basic model is unavailable 
for testing and may include alternative models or basic models.
    (iii) DOE will state in the test notice that it will select the 
units of a basic model to be tested from the manufacturer, from one or 
more distributors, and/or from one or more retailers. If any unit is 
selected from a distributor or retailer, the manufacturer shall make 
arrangements with the distributor or retailer for compensation for or 
replacement of any such units.
    (iv) DOE may require in the test notice that the manufacturer of a 
basic model ship or cause to be shipped from a retailer or distributor 
at its expense the requested number of units of a basic model specified 
in such test notice to the testing laboratory specified in the test 
notice. The manufacturer shall ship the specified initial test unit(s) 
of the basic model to the testing laboratory within 5 working days from 
the time units are selected.
    (v) If DOE determines that the units identified are low-volume or 
built-to-order products, DOE will contact the manufacturer to develop a 
plan for enforcement testing in lieu of paragraphs (ii)-(iv) of this 
section.
    (2) [Reserved]
    (c) Test unit selection. (1) To select units for testing from a:
    (i) Manufacturer's warehouse, distributor, or other facility 
affiliated with the manufacturer. DOE will select a batch sample at 
random in accordance with the provisions in paragraph (e) of this 
section and the conditions specified in the test notice. DOE will 
randomly select an initial test sample

[[Page 247]]

of units from the batch sample for testing in accordance with appendices 
A through C of this subpart. DOE will make a determination whether an 
alternative sample size will be used in accordance with the provisions 
in paragraph (e)(1)(iv) of this section.
    (ii) Retailer or other facility not affiliated with the 
manufacturer. DOE will select an initial test sample of units at random 
that satisfies the minimum units necessary for testing in accordance 
with the provisions in appendices A through C of this subpart and the 
conditions specified in the test notice. Depending on the results of the 
testing, DOE may select additional units for testing from a retailer in 
accordance with appendices A through C of this subpart. If the full 
sample is not available from a retailer, DOE will make a determination 
whether an alternative sample size will be used in accordance with the 
provisions in paragraph (e)(1)(iv) of this section.
    (iii) Previously commissioned commercial packaged boilers with a 
rated input greater than 5,000,000 Btu/h. DOE may test a sample of at 
least one unit in the location in which it was commissioned for use.
    (2) Units tested in accordance with the applicable test procedure 
under this part by DOE or another Federal agency, pursuant to other 
provisions or programs, may count toward units in the test sample.
    (3) The resulting test data shall constitute official test data for 
the basic model. Such test data will be used by DOE to make a 
determination of compliance or noncompliance if a sufficient number of 
tests have been conducted to satisfy the requirements of paragraph (e) 
of this section and appendices A through C of this subpart.
    (d) Test unit preparation. (1) Prior to and during testing, a test 
unit selected for enforcement testing shall not be prepared, modified, 
or adjusted in any manner unless such preparation, modification, or 
adjustment is allowed by the applicable DOE test procedure. One test 
shall be conducted for each test unit in accordance with the applicable 
test procedures prescribed in parts 430 and 431.
    (2) No quality control, testing or assembly procedures shall be 
performed on a test unit, or any parts and subassemblies thereof, that 
is not performed during the production and assembly of all other units 
included in the basic model.
    (3) A test unit shall be considered defective if such unit is 
inoperative or is found to be in noncompliance due to failure of the 
unit to operate according to the manufacturer's design and operating 
instructions. Defective units, including those damaged due to shipping 
or handling, shall be reported immediately to DOE. DOE may authorize 
testing of an additional unit on a case-by-case basis.
    (e) Basic model compliance. DOE will evaluate whether a basic model 
complies with the applicable energy conservation standard(s) based on 
testing conducted in accordance with the applicable test procedures 
specified in parts 430 and 431 of this chapter, and with the following 
statistical sampling procedures:
    (1) For products with applicable energy conservation standard(s) in 
Sec. 430.32 of this chapter, and commercial prerinse spray valves, 
illuminated exit signs, traffic signal modules and pedestrian modules, 
commercial clothes washers, dedicated-purpose pool pumps, and metal 
halide lamp ballasts, DOE will use a sample size of not more than 21 
units and follow the sampling plans in appendix A of this subpart 
(Sampling for Enforcement Testing of Covered Consumer Products and 
Certain High-Volume Commercial Equipment).
    (2) For automatic commercial ice makers; commercial refrigerators, 
freezers, and refrigerator-freezers; refrigerated bottled or canned 
vending machines; commercial air conditioners and heat pumps; commercial 
packaged boilers; commercial warm air furnaces; commercial water heating 
equipment; and walk-in cooler and walk-in freezer refrigeration systems, 
DOE will use an initial sample size of not more than four units and 
follow the sampling plans in appendix B of this subpart (Sampling Plan 
for Enforcement Testing of Covered Equipment and Certain Low-Volume 
Covered Products).
    (3) If fewer than four units of a basic model are available for 
testing (under paragraphs (e)(1) or (2) of this section)

[[Page 248]]

when the manufacturer receives the notice, then:
    (i) DOE will test the available unit(s); or
    (ii) If one or more other units of the basic model are expected to 
become available within 30 calendar days, DOE may instead, at its 
discretion, test either:
    (A) The available unit(s) and one or more of the other units that 
subsequently become available (up to a maximum of four); or
    (B) Up to four of the other units that subsequently become 
available.
    (4) For distribution transformers, DOE will use an initial sample 
size of not more than five units and follow the sampling plans in 
appendix C of this subpart (Sampling Plan for Enforcement Testing of 
Distribution Transformers). If fewer than five units of a basic model 
are available for testing when the manufacturer receives the test 
notice, then:
    (i) DOE will test the available unit(s); or
    (ii) If one or more other units of the basic model are expected to 
become available within 30 calendar days, DOE may instead, at its 
discretion, test either:
    (A) The available unit(s) and one or more of the other units that 
subsequently become available (up to a maximum of five); or
    (B) Up to five of the other units that subsequently become 
available.
    (5) For pumps subject to the standards specified in Sec. 431.465(a) 
of this chapter, DOE will use an initial sample size of not more than 
four units and will determine compliance based on the arithmetic mean of 
the sample.
    (6) For uninterruptible power supplies, if a basic model is 
certified for compliance to the applicable energy conservation 
standard(s) in Sec. 430.32 of this chapter according to the sampling 
plan in Sec. 429.39(a)(2)(iv)(A) of this chapter, DOE will use a sample 
size of not more than 21 units and follow the sampling plan in appendix 
A of this subpart (Sampling for Enforcement Testing of Covered Consumer 
Products and Certain High-Volume Commercial Equipment). If a basic model 
is certified for compliance to the applicable energy conservation 
standard(s) in Sec. 430.32 of this chapter according to the sampling 
plan in Sec. 429.39(a)(2)(iv)(B) of this chapter, DOE will use a sample 
size of at least one unit and follow the sampling plan in appendix D of 
this subpart (Sampling for Enforcement Testing of Uninterruptible Power 
Supplies).
    (7) Notwithstanding paragraphs (e)(1) through (6) of this section, 
if testing of the available or subsequently available units of a basic 
model would be impractical, as for example when a basic model has 
unusual testing requirements or has limited production, DOE may in its 
discretion decide to base the determination of compliance on the testing 
of fewer than the otherwise required number of units.
    (8) When DOE makes a determination in accordance with paragraph 
(e)(7) of this section to test less than the number of units specified 
in paragraphs (e)(1) through (6) of this section, DOE will base the 
compliance determination on the results of such testing in accordance 
with appendix B of this subpart (Sampling Plan for Enforcement Testing 
of Covered Equipment and Certain Low-Volume Covered Products) using a 
sample size (n1) equal to the number of units tested.
    (9) For the purposes of this section, available units are those that 
are available for distribution in commerce within the United States.

Sec. 429.114  Notice of noncompliance and notice to cease distribution
of a basic model.

    (a) In the event that DOE determines a basic model is noncompliant 
with an applicable energy conservation standard, or if a manufacturer or 
private labeler determines a basic model to be in noncompliance, DOE may 
issue a notice of noncompliance determination to the manufacturer or 
private labeler. This notice of noncompliance determination will notify 
the manufacturer or private labeler of its obligation to:
    (1) Immediately cease distribution in commerce of the basic model;

[[Page 249]]

    (2) Give immediate written notification of the determination of 
noncompliance to all persons to whom the manufacturer has distributed 
units of the basic model manufactured since the date of the last 
determination of compliance; and
    (3) Provide DOE, within 30 calendar days of the request, records, 
reports and other documentation pertaining to the acquisition, ordering, 
storage, shipment, or sale of a basic model determined to be in 
noncompliance.
    (b) In the event that DOE determines a manufacturer has failed to 
comply with an applicable certification requirement with respect to a 
particular basic model, DOE may issue a notice of noncompliance 
determination to the manufacturer or private labeler. This notice of 
noncompliance determination will notify the manufacturer or private 
labeler of its obligation to:
    (1) Immediately cease distribution in commerce of the basic model;
    (2) Immediately comply with the applicable certification 
requirement; and/or
    (3) Provide DOE within 30 days of the request, records, reports and 
other documentation pertaining to the acquisition, ordering, storage, 
shipment, or sale of the basic model.
    (c) If a manufacturer or private labeler fails to comply with the 
required actions in the notice of noncompliance determination as set 
forth in paragraphs (a) or (b) of this section, the General Counsel (or 
delegee) may seek, among other remedies, injunctive action and civil 
penalties, where appropriate.
    (d) The manufacturer may modify a basic model determined to be 
noncompliant with an applicable energy conservation standard in such 
manner as to make it comply with the applicable standard. Such modified 
basic model shall then be treated as a new basic model and must be 
certified in accordance with the provisions of this part; except that in 
addition to satisfying all requirements of this part, any models within 
the basic model must be assigned new model numbers and the manufacturer 
shall also maintain, and provide upon request to DOE, records that 
demonstrate that modifications have been made to all units of the new 
basic model prior to distribution in commerce.



Sec. 429.116  Additional certification testing requirements.

    Pursuant to Sec. 429.102(b)(2), if DOE determines that independent, 
third-party testing is necessary to ensure a manufacturer's compliance 
with the rules of this part, part 430, or part 431, a manufacturer must 
base its certification of a basic model under subpart B of this part on 
independent, third-party laboratory testing.



Sec. 429.118  Injunctions.

    If DOE has reason to seek an injunction under the Act:
    (a) DOE will notify the manufacturer, private labeler or any other 
person as required, of the prohibited act at issue and DOE's intent to 
seek a judicial order enjoining the prohibited act unless the 
manufacturer, private labeler or other person, delivers to DOE within 15 
calendar days a corrective action and compliance plan, satisfactory to 
DOE, of the steps it will take to ensure that the prohibited act ceases. 
DOE will monitor the implementation of such plan.
    (b) If the manufacturer, private labeler or any other person as 
required, fails to cease engaging in the prohibited act or fails to 
provide a satisfactory corrective action and compliance plan, DOE may 
seek an injunction.



Sec. 429.120  Maximum civil penalty.

    Any person who knowingly violates any provision of Sec. 429.102(a) 
may be subject to assessment of a civil penalty of no more than $440 for 
each violation. As to Sec. 429.102(a)(1) with respect to failure to 
certify, and as to Sec. 429.102(a)(2), (5) through (9), each unit of a 
covered product or covered equipment distributed in violation of such 
paragraph shall constitute a separate violation. For violations of Sec. 
429.102(a)(1), (3), and (4), each day of noncompliance shall constitute 
a separate violation for each basic model at issue.

[76 FR 12451, Mar. 7, 2011, as amended at 81 FR 41794, June 28, 2016; 81 
FR 96351, Dec. 30, 2016]

    (a) The General Counsel (or delegee) shall provide notice of any 
proposed civil penalty.
    (b) The notice of proposed penalty shall:
    (1) Include the amount of the proposed penalty;
    (2) Include a statement of the material facts constituting the 
alleged violation; and
    (3) Inform the person of the opportunity to elect in writing within 
30 calendar days of receipt of the notice to have the procedures of 
Sec. 429.128 (in lieu of those of Sec. 429.126) apply with respect to 
the penalty.



Sec. 429.124  Election of procedures.

    (a) In responding to a notice of proposed civil penalty, the 
respondent may request:
    (1) An administrative hearing before an Administrative Law Judge 
(ALJ) under Sec. 429.126 of this part; or
    (2) Elect to have the procedures of Sec. 429.128 apply.
    (b) Any election to have the procedures of Sec. 429.128 apply may 
not be revoked except with the consent of the General Counsel (or 
delegee).
    (c) If the respondent fails to respond to a notice issued under 
Sec. 429.120 or otherwise fails to indicate its election of procedures, 
DOE shall refer the civil penalty action to an ALJ for a hearing under 
Sec. 429.126.



Sec. 429.126  Administrative law judge hearing and appeal.

    (a) When elected pursuant to Sec. 429.124, DOE shall refer a civil 
penalty action brought under Sec. 429.122 of this part to an ALJ, who 
shall afford the respondent an opportunity for an agency hearing on the 
record.
    (b) After consideration of all matters of record in the proceeding, 
the ALJ will issue a recommended decision, if appropriate, recommending 
a civil penalty. The decision will include a statement of the findings 
and conclusions, and the reasons therefore, on all material issues of 
fact, law, and discretion.
    (c)(1) The General Counsel (or delegee) shall adopt, modify, or set 
aside the conclusions of law or discretion contained in the ALJ's 
recommended decision and shall set forth a final order assessing a civil 
penalty. The General Counsel (or delegee) shall include in the final 
order the ALJ's findings of fact and the reasons for the final agency 
actions.
    (2) Any person against whom a penalty is assessed under this section 
may, within 60 calendar days after the date of the final order assessing 
such penalty, institute an action in the United States Court of Appeals 
for the appropriate judicial circuit for judicial review of such order 
in accordance with chapter 7 of title 5, United States Code. The court 
shall have jurisdiction to enter a judgment affirming, modifying, or 
setting aside in whole or in part, the final order, or the court may 
remand the proceeding to the Department for such further action as the 
court may direct.



Sec. 429.128  Immediate issuance of order assessing civil penalty.

    (a) If the respondent elects to forgo an agency hearing pursuant to 
Sec. 429.124, the General Counsel (or delegee) shall issue an order 
assessing the civil penalty proposed in the notice of proposed penalty 
under Sec. 429.122, 30 calendar days after the respondent's receipt of 
the notice of proposed penalty.
    (b) If within 60 calendar days of receiving the assessment order in 
paragraph (a) of this section the respondent does not pay the civil

    (a) DOE may compromise, modify, or remit, with or without 
conditions, any civil penalty (with leave of court if necessary).
    (b) In exercising its authority under paragraph (a) of this section, 
DOE may consider the nature and seriousness of the violation, the 
efforts of the respondent to remedy the violation in a timely manner, 
and other factors as justice may require.
    (c) DOE's authority to compromise, modify or remit a civil penalty 
may be exercised at any time prior to a final decision by the United 
States Court of Appeals if Sec. 429.126 procedures are utilized, or 
prior to a final decision by the United States District Court, if Sec. 
429.128 procedures are utilized.
    (d) Notwithstanding paragraph (a) of this section, DOE or the 
respondent may propose to settle the case. If a settlement is agreed to 
by the parties, the respondent is notified and the case is closed in 
accordance with the terms of the settlement.



Sec. 429.134  Product-specific enforcement provisions.

    (a) General. The following provisions apply to assessment and 
enforcement testing of the relevant products and equipment.
    (b) Refrigerators, refrigerator-freezers, and freezers-- (1) 
Verification of total refrigerated volume. The total refrigerated volume 
of the basic model will be measured pursuant to the test requirements of 
10 CFR part 430 for each unit tested. The results of the measurement(s) 
will be averaged and compared to the value of total refrigerated volume 
certified by the manufacturer. The certified total refrigerated volume 
will be considered valid only if:
    (i) The measurement is within two percent, or 0.5 cubic feet (0.2 
cubic feet for compact products), whichever is greater, of the certified 
total refrigerated volume, or
    (ii) The measurement is greater than the certified total 
refrigerated volume.
    (A) If the certified total refrigerated volume is found to be valid, 
the certified adjusted total volume will be used as the basis for 
calculation of maximum allowed energy use for the basic model.
    (B) If the certified total refrigerated volume is found to be 
invalid, the average measured adjusted total volume, rounded to the 
nearest 0.1 cubic foot, will serve as the basis for calculation of 
maximum allowed energy use for the tested basic model.
    (2) Test for models with two compartments, each having its own user-
operable temperature control. The test described in section 3.3 of the 
applicable test procedure for refrigerators or refrigerator-freezers in 
appendix A to subpart B of 10 CFR part 430 shall be used for all units 
of a tested basic model before DOE makes a determination of 
noncompliance with respect to the basic model.
    (c) Clothes washers. (1) Determination of Remaining Moisture 
Content. The procedure for determining remaining moisture content (RMC) 
will be performed once in its entirety, pursuant to the test 
requirements of section 3.8 of appendix J1 and appendix J2 to subpart B 
of part 430, for each unit tested.
    (i) The measured RMC value of a tested unit will be considered the 
tested unit's final RMC value if the measured RMC value is within two 
RMC percentage points of the certified RMC value of the basic model 
(expressed as a percentage), or is lower than the certified RMC value.
    (ii) If the measured RMC value of a tested unit is more than two RMC 
percentage points higher than the certified RMC value of the basic 
model, DOE will perform two additional replications of the RMC 
measurement procedure, each pursuant to the provisions of section 3.8.5 
of appendix J1 and appendix J2 to subpart B of part 430, for a total of 
three independent RMC measurements of the tested unit. The average of 
the three RMC measurements will be the tested unit's final RMC value and 
will be used as the basis for the calculation of per-cycle energy 
consumption for removal of moisture from the test load for that unit.
    (2) [Reserved]

[[Page 252]]

    (d) Residential Water Heaters and Residential-Duty Commercial Water 
Heaters--(1) Verification of first-hour rating and maximum GPM rating. 
The first-hour rating or maximum gallons per minute (GPM) rating of the 
basic model will be measured pursuant to the test requirements of 10 CFR 
part 430 for each unit tested. The mean of the measured values will be 
compared to the rated values of first-hour rating or maximum GPM rating 
as certified by the manufacturer. The certified rating will be 
considered valid only if the measurement is within five percent of the 
certified rating.
    (i) If the rated value of first-hour rating or maximum GPM rating is 
found to be within 5 percent of the mean of the measured values, then 
the rated value will be used as the basis for determining the applicable 
draw pattern pursuant to the test requirements of 10 CFR part 430 for 
each unit tested.
    (ii) If the rated value of first-hour rating or maximum GPM rating 
is found to vary more than 5 percent from the measured values, then the 
mean of the measured values will serve as the basis for determining the 
applicable draw pattern pursuant to the test requirements of 10 CFR part 
430 for each unit tested.
    (2) Verification of rated storage volume. The storage volume of the 
basic model will be measured pursuant to the test requirements of 
appendix E to subpart B of 10 CFR part 430 for each unit tested. The 
mean of the measured values will be compared to the rated storage volume 
as certified by the manufacturer. The rated value will be considered 
valid only if the measurement is within 3 percent of the certified 
rating.
    (i) If the rated storage volume is found to be within 3 percent of 
the mean of the measured value of storage volume, then the rated value 
will be used as the basis for calculation of the required uniform energy 
factor for the basic model.
    (ii) If the rated storage volume is found to vary more than 3 
percent from the mean of the measured values, then the mean of the 
measured values will be used as the basis for calculation of the 
required uniform energy factor for the basic model.
    (e) Packaged terminal air conditioners and packaged terminal heat 
pumps--(1) Verification of cooling capacity. The total cooling capacity 
of the basic model will be measured pursuant to the test requirements of 
10 CFR part 431 for each unit tested. The results of the measurement(s) 
will be averaged and compared to the value of cooling capacity certified 
by the manufacturer. The certified cooling capacity will be considered 
valid only if the average measured cooling capacity is within five 
percent of the certified cooling capacity.
    (i) If the certified cooling capacity is found to be valid, that 
cooling capacity will be used as the basis for calculation of minimum 
allowed EER (and minimum allowed COP for PTHP models) for the basic 
model.
    (ii) If the certified cooling capacity is found to be invalid, the 
average measured cooling capacity will serve as the basis for 
calculation of minimum allowed EER (and minimum allowed COP for PTHP 
models) for the tested basic model.
    (2) [Reserved]
    (f) Dehumidifiers--(1) Verification of capacity. The capacity will 
be measured pursuant to the test requirements of part 430 for each unit 
tested. The results of the measurement(s) will be averaged and compared 
to the value of capacity certified by the manufacturer for the basic 
model. The certified capacity will be considered valid only if the 
measurement is within five percent, or 1.00 pint per day, whichever is 
greater, of the certified capacity.
    (i) If the certified capacity is found to be valid, the certified 
capacity will be used as the basis for determining the minimum energy 
factor or integrated energy factor allowed for the basic model.
    (ii) If the certified capacity is found to be invalid, the average 
measured capacity of the units in the sample will be used as the basis 
for determining the minimum energy factor or integrated energy factor 
allowed for the basic model.
    (2) Verification of whole-home dehumidifier case volume. The case 
volume will be measured pursuant to the test requirements of part 430 
for each unit

[[Page 253]]

tested. The results of the measurement(s) will be averaged and compared 
to the value of case volume certified by the manufacturer for the basic 
model. The certified case volume will be considered valid only if the 
measurement is within two percent, or 0.2 cubic feet, whichever is 
greater, of the certified case volume.
    (i) If the certified case volume is found to be valid, the certified 
case volume will be used as the basis for determining the minimum 
integrated energy factor allowed for the basic model.
    (ii) If the certified case volume is found to be invalid, the 
average measured case volume of the units in the sample will be used as 
the basis for determining the minimum integrated energy factor allowed 
for the basic model.
    (g) Air-cooled small (=65,000 Btu/h and <135,000 Btu/h), 
large (=135,000 Btu/h and <240,000 Btu/h), and very large 
(=240,000 Btu/h and <760,000 Btu/h) commercial package air 
conditioning and heating equipment--verification of cooling capacity. 
The cooling capacity of each tested unit of the basic model will be 
measured pursuant to the test requirements of part 431 of this chapter. 
The mean of the measurement(s) will be used to determine the applicable 
standards for purposes of compliance.
    (h) Residential boilers--test protocols for functional verification 
of automatic means for adjusting water temperature. These tests are 
intended to verify the functionality of the design requirement that a 
boiler has an automatic means for adjusting water temperature for 
single-stage, two-stage, and modulating boilers. These test methods are 
intended to permit the functional testing of a range of control 
strategies used to fulfill this design requirement. Section 2, 
Definitions, and paragraph 6.1.a of appendix N to subpart B of part 430 
of this chapter apply for the purposes of this paragraph (h).
    (1) Test protocol for all products other than single-stage products 
employing burner delay. This test is intended to verify whether an 
automatic means for adjusting water temperature other than burner delay 
produces an incremental change in water supply temperature in response 
to an incremental change in inferred heat load.
    (i) Boiler setup--(A) Boiler installation. Boiler installation in 
the test room shall be in accordance with the setup and apparatus 
requirements of section 6 of appendix N to subpart B of 10 CFR part 430.
    (B) Establishing flow rate and temperature rise. Start the boiler 
without enabling the means for adjusting water temperature. Establish a 
water flow rate that allows for a water temperature rise of greater than 
or equal to 20 [deg]F at maximum input rate.
    (C) Temperature stabilization. Temperature stabilization is deemed 
to be obtained when the boiler supply water temperature does not vary by 
more than 3 [deg]F over a period of five minutes.
    (D) Adjust the inferential load controller. (1) Adjust the boiler 
controls (in accordance with the I&O manual) to the default setting that 
allows for activation of the means for adjusting water temperature. For 
boiler controls that do not allow for control adjustment during active 
mode operation, terminate call for heat and adjust the inferential load 
controller in accordance with the I&O manual and then reinitiate call 
for heat.
    (2) If the means for adjusting water temperature uses outdoor 
temperature reset, the maximum outdoor temperature setting (if equipped) 
should be set to a temperature high enough that the boiler operates 
continuously during the duration of this test (i.e., if the conditions 
in paragraph (h)(1)(ii)(A) of this section equal room ambient 
temperature, then the maximum outdoor temperature should be set at a 
temperature greater than the ambient air temperature during the test).
    (ii) Establish low inferred load conditions at minimum boiler supply 
water temperature--(A) Establish low inferred load conditions. (1) 
Establish the inferred load conditions (simulated using a controlling 
parameter, such as outdoor temperature, thermostat patterns, or boiler 
cycling) so that the supply water temperature is maintained at the 
minimum supply water temperature prescribed by the boiler manufacturer's 
temperature reset control strategy found in the I&O manual.

[[Page 254]]

    (2) The minimum supply water temperature of the default temperature 
reset curve is usually provided in the I&O manual. If there is no 
recommended minimum supply water temperature, set the minimum supply 
water temperature equal to 20 [deg]F less than the high supply water 
temperature specified in paragraph (h)(1)(iii)(A) of this section.
    (B) Supply water temperature stabilization at low inferred load. (1) 
Maintain the call for heat until the boiler supply water temperature has 
stabilized. Temperature stabilization is deemed to be obtained when the 
boiler supply water temperature does not vary by more than 3 [deg]F over a period of five minutes. The duration of 
time required to stabilize the supply water, following the procedure in 
paragraph (h)(1)(ii)(A) of this section, is dependent on the reset 
strategy and may vary from model to model.
    (2) Record the boiler supply water temperature while the temperature 
is stabilized.
    (iii) Establish high inferred load conditions at maximum boiler 
supply water temperature--(A) Establish high inferred load conditions. 
Establish the inferred load conditions so that the supply water 
temperature is set to the maximum allowable supply water temperature as 
prescribed in the I&O manual, or if there is no recommendation, set to a 
temperature greater than 170 [deg]F.
    (B) Supply water temperature stabilization at high inferred load. 
(1) Maintain the call for heat until the boiler supply water temperature 
has stabilized. Temperature stabilization is deemed to be obtained when 
the boiler supply water temperature does not vary by more than 3 [deg]F over a period of five minutes. The duration of 
time required to stabilize the supply water, following the procedure in 
paragraph (h)(1)(iii)(A) of this section, is dependent on the reset 
strategy and may vary from model to model.
    (2) Record the boiler supply water temperature while the temperature 
is stabilized.
    (3) Terminate the call for heat.
    (iv) [Reserved]
    (2) Test protocol for single-stage products employing burner delay. 
This test will be used in place of paragraph (h)(1) of this section for 
products manufacturers have certified to DOE under Sec. 429.18(b)(3) as 
employing a burner delay automatic means strategy. This test verifies 
whether the automatic means in single-stage boiler products establishes 
a burner delay upon a call for heat until the means has determined that 
the inferred heat load cannot be met by the residual heat of the water 
in the system.
    (i) Boiler setup--(A) Boiler installation. Boiler installation in 
the test room shall be in accordance with the setup and apparatus 
requirements by section 6.0 of appendix N to subpart B of 10 CFR part 
430.
    (B) Activation of controls. Adjust the boiler controls in accordance 
with the I&O manual at the default setting that allows for activation of 
the means for adjusting water temperature.
    (C) Adjustment of water flow and temperature. The flow and 
temperature of inlet water to the boiler shall be capable of being 
adjusted manually.
    (ii) Boiler heat-up--(A) Boiler start-up. Power up the boiler and 
initiate a call for heat.
    (B) Adjustment of firing rate. Adjust the boiler's firing rate to 
within 5% of its maximum rated input.
    (C) Establishing flow rate and temperature rise. Adjust the water 
flow through the boiler to achieve a [Delta]T of 20 [deg]F (2 [deg]F) or greater with an inlet water temperature 
equal to 140 [deg]F (2 [deg]F).
    (D) Terminate the call for heating. Terminate the call for heat, 
stop the flow of water through the boiler, and record the time at 
termination.
    (iii) Verify burner delay--(A) Reinitiate call for heat. Within 
three (3) minutes of termination (paragraph (h)(2)(ii)(D) of this 
section) and without adjusting the inlet water flow rate or temperature 
as specified in paragraph (h)(2)(ii)(C) of this section, reinitiate the 
call for heat and water flow and record the time.
    (B) Verify burner ignition. At 15-second intervals, record time and 
supply water temperature until the main burner ignites.
    (C) Terminate the call for heat.
    (iv) [Reserved]
    (i) Pumps--(1) General purpose pumps. (i) The volume rate of flow 
(flow rate) at BEP and nominal speed of rotation

[[Page 255]]

of each tested unit of the basic model will be measured pursuant to the 
test requirements of Sec. 431.464 of this chapter, where the value of 
volume rate of flow (flow rate) at BEP and nominal speed of rotation 
certified by the manufacturer will be treated as the expected BEP flow 
rate. The results of the measurement(s) will be compared to the value of 
volume rate of flow (flow rate) at BEP and nominal speed of rotation 
certified by the manufacturer. The certified volume rate of flow (flow 
rate) at BEP and nominal speed of rotation will be considered valid only 
if the measurement(s) (either the measured volume rate of flow (flow 
rate) at BEP and nominal speed of rotation for a single unit sample or 
the average of the measured flow rates for a multiple unit sample) is 
within five percent of the certified volume rate of flow (flow rate) at 
BEP and nominal speed of rotation.
    (A) If the representative value of volume rate of flow (flow rate) 
at BEP and nominal speed of rotation is found to be valid, the measured 
volume rate of flow (flow rate) at BEP and nominal speed of rotation 
will be used in subsequent calculations of constant load pump energy 
rating (PERCL) and constant load pump energy index 
(PEICL) or variable load pump energy rating 
(PERVL) and variable load pump energy index 
(PEIVL) for that basic model.
    (B) If the representative value of volume rate of flow (flow rate) 
at BEP and nominal speed of rotation is found to be invalid, the mean of 
all the measured volume rate of flow (flow rate) at BEP and nominal 
speed of rotation values determined from the tested unit(s) will serve 
as the new expected BEP flow rate and the unit(s) will be retested until 
such time as the measured rate of flow (flow rate) at BEP and nominal 
speed of rotation is within 5 percent of the expected BEP flow rate.
    (ii) DOE will test each pump unit according to the test method 
specified by the manufacturer in the certification report submitted 
pursuant to Sec. 429.59(b).
    (2) Dedicated-purpose pool pumps. (i) The rated hydraulic horsepower 
of each tested unit of the basic model of dedicated-purpose pool pump 
will be measured pursuant to the test requirements of Sec. 431.464(b) 
of this chapter and the result of the measurement(s) will be compared to 
the value of rated hydraulic horsepower certified by the manufacturer. 
The certified rated hydraulic horsepower will be considered valid only 
if the measurement(s) (either the measured rated hydraulic horsepower 
for a single unit sample or the average of the measured rated hydraulic 
horsepower values for a multiple unit sample) is within 5 percent of the 
certified rated hydraulic horsepower.
    (A) If the representative value of rated hydraulic horsepower is 
found to be valid, the value of rated hydraulic horsepower certified by 
the manufacturer will be used to determine the standard level for that 
basic model.
    (B) If the representative value of rated hydraulic horsepower is 
found to be invalid, the mean of all the measured rated hydraulic 
horsepower values determined from the tested unit(s) will be used to 
determine the standard level for that basic model.
    (ii) To verify the self-priming capability of non-self-priming pool 
filter pumps and of self-priming pool filter pumps that are not 
certified with NSF/ANSI 50-2015 (incorporated by reference, see Sec. 
429.4) as self-priming, the vertical lift and true priming time of each 
tested unit of the basic model of self-priming or non-self-priming pool 
filter pump will be measured pursuant to the test requirements of Sec. 
431.464(b) of this chapter.
    (A) For self-priming pool filter pumps that are not certified with 
NSF/ANSI 50-2015 as self-priming, at a vertical lift of 5.0 feet, the 
result of the true priming time measurement(s) will be compared to the 
value of true priming time certified by the manufacturer. The certified 
value of true priming time will be considered valid only if the 
measurement(s) (either the measured true priming time for a single unit 
sample or the average of true priming time values for a multiple unit 
sample) is within 5 percent of the certified value of true priming time.
    (1) If the representative value of true priming time is found to be 
valid, the value of true priming time certified by the manufacturer will 
be used to determine the appropriate equipment class

[[Page 256]]

and standard level for that basic model.
    (2) If the representative value of true priming time is found to be 
invalid, the mean of the values of true priming time determined from the 
tested unit(s) will be used to determine the appropriate equipment class 
and standard level for that basic model.
    (B) For non-self-priming pool filter pumps, at a vertical lift of 
5.0 feet, the result of the true priming time measurement(s) (either the 
measured true priming time for a single unit sample or the average of 
true priming time values, for a multiple unit sample) will be compared 
to the value of true priming time referenced in the definition of non-
self-priming pool filter pump at Sec. 431.462 (10.0 minutes).
    (1) If the measurement(s) of true priming time are greater than 95 
percent of the value of true priming time referenced in the definition 
of non-self-priming pool filter pump at Sec. 431.462 with a vertical 
lift of 5.0 feet, the DPPP model will be considered a non-self-priming 
pool filter pump for the purposes of determining the appropriate 
equipment class and standard level for that basic model.
    (2) If the conditions specified in paragraph (i)(2)(ii)(B)(1) of 
this section are not satisfied, then the DPPP model will be considered a 
self-priming pool filter pump for the purposes of determining the 
appropriate equipment class and standard level for that basic model.
    (iii) To verify the maximum head of self-priming pool filter pump, 
non-self-priming pool filter pumps, and waterfall pumps, the maximum 
head of each tested unit of the basic model of self-priming pool filter 
pump, non-self-priming pool filter pump, or waterfall pump will be 
measured pursuant to the test requirements of Sec. 431.464(b) of this 
chapter and the result of the measurement(s) will be compared to the 
value of maximum head certified by the manufacturer. The certified value 
of maximum head will be considered valid only if the measurement(s) 
(either the measured maximum head for a single unit sample or the 
average of the maximum head values for a multiple unit sample) is within 
5 percent of the certified values of maximum head.
    (A) If the representative value of maximum head is found to be 
valid, the value of maximum head certified by the manufacturer will be 
used to determine the appropriate equipment class and standard level for 
that basic model.
    (B) If the representative value of maximum head is found to be 
invalid, the measured value(s) of maximum head determined from the 
tested unit(s) will be used to determine the appropriate equipment class 
and standard level for that basic model.
    (iv) To verify that a DPPP model complies with the applicable freeze 
protection control design requirements, the initiation temperature, run-
time, and speed of rotation of the default control configuration of each 
tested unit of the basic model of dedicated-purpose pool pump will be 
evaluated according to the procedure specified in paragraph 
(i)(2)(iv)(A) of this section:
    (A)(1) Set up and configure the dedicated-purpose pool pump under 
test according to the manufacturer instructions, including any necessary 
initial priming, in a test apparatus as described in appendix A of HI 
40.6-2014-B (incorporated by reference, see Sec. 429.4), except that 
the ambient temperature registered by the freeze protection ambient 
temperature sensor will be able to be measured and controlled by, for 
example, exposing the freeze protection temperature sensor to a specific 
temperature by submerging the sensor in a water bath of known 
temperature, by adjusting the actual ambient air temperature of the test 
chamber and measuring the temperature at the freeze protection ambient 
temperature sensor location, or by other means that allows the ambient 
temperature registered by the freeze protection temperature sensor to be 
reliably simulated, varied, and measured. Do not adjust the default 
freeze protection control settings or enable the freeze protection 
control if it is shipped disabled.
    (2) Activate power to the pump with the flow rate set to zero (i.e., 
the pump is energized but not circulating water). Set the ambient 
temperature to 42.0  0.5[emsp14] [deg]F and allow 
the temperature to stabilize, where stability is determined in 
accordance with section 40.6.3.2.2 of

[[Page 257]]

HI 40.6-2014-B. After 5 minutes, decrease the temperature measured by 
the freeze protection temperature sensor by 1.0  
0.5[emsp14] [deg]F and allow the temperature to stabilize. After each 
reduction in ambient temperature and subsequent stabilization, record 
the DPPP rotating speed, if any, and freeze protection ambient 
temperature reading, where the ``freeze protection ambient temperature 
reading'' is representative of the temperature measured by the freeze 
protection ambient temperature sensor, which may be recorded by a 
variety of means depending on how the temperature is being simulated and 
controlled. If no flow is initiated, record zero rpm or no flow. 
Continue decreasing the temperature measured by the freeze protection 
temperature sensor by 1.0  0.5[emsp14] [deg]F 
after 5.0 minutes of stable operation at the previous temperature 
reading until the pump freeze protection initiates water circulation or 
until the ambient temperature of 38.0  0.5[emsp14] 
[deg]F has been evaluated (i.e., the end of the 5.0 minute interval of 
38.0[emsp14] [deg]F), whichever occurs first.
    (3) If and when the DPPP freeze protection controls initiate water 
circulation, increase the ambient temperature reading registered by the 
freeze protection temperature sensor to a temperature of 42.0  0.5[emsp14] [deg]F and maintain that temperature for 
60.0 minutes. Do not modify or interfere with the operation of the DPPP 
freeze protection operating cycle. After 60.0 minutes, record the freeze 
protection ambient temperature and rotating speed, if any, of the 
dedicated-purpose pool pump under test.
    (B) If the dedicated-purpose pool pump initiates water circulation 
at a temperature greater than 40.0[emsp14] [deg]F; if the dedicated-
purpose pool pump was still circulating water after 60.0 minutes of 
operation at 42.0  0.5[emsp14] [deg]F; or if 
rotating speed measured at any point during the DPPP freeze protection 
control test in paragraph (i)(2)(iii)(A) of this section was greater 
than one-half of the maximum rotating speed of the DPPP model certified 
by the manufacturer, that DPPP model is deemed to not comply with the 
design requirement for freeze protection controls.
    (C) If none of the conditions specified in paragraph (i)(2)(iv)(B) 
of this section are met, including if the DPPP freeze protection control 
does not initiate water circulation at all during the test, the 
dedicated-purpose pool pump under test is deemed compliant with the 
design requirement for freeze protection controls.
    (j) Refrigerated bottled or canned beverage vending machines--(1) 
Verification of refrigerated volume. The refrigerated volume (V) of each 
tested unit of the basic model will be measured pursuant to the test 
requirements of 10 CFR 431.296. The results of the measurement(s) will 
be compared to the representative value of refrigerated volume certified 
by the manufacturer. The certified refrigerated volume will be 
considered valid only if the measurement(s) (either the measured 
refrigerated volume for a single unit sample or the average of the 
measured refrigerated volumes for a multiple unit sample) is within five 
percent of the certified refrigerated volume.
    (i) If the representative value of refrigerated volume is found to 
be valid, the certified refrigerated volume will be used as the basis 
for calculation of maximum daily energy consumption for the basic model.
    (ii) If the representative value of refrigerated volume is found to 
be invalid, the average measured refrigerated volume determined from the 
tested unit(s) will serve as the basis for calculation of maximum daily 
energy consumption for the tested basic model.
    (2) Verification of surface area, transparent, and non-transparent 
areas. The percent transparent surface area on the front side of the 
basic model will be measured pursuant to these requirements for the 
purposes of determining whether a given basic model meets the definition 
of Class A or Combination A, as presented at 10 CFR 431.292. The 
transparent and non-transparent surface areas shall be determined on the 
front side of the beverage vending machine at the outermost surfaces of 
the beverage vending machine cabinet, from edge to edge, excluding any 
legs or other protrusions that extend beyond the dimensions of the 
primary cabinet. Determine the transparent and non-transparent areas on 
each side

[[Page 258]]

of a beverage vending machine as described in paragraphs (j)(2)(i) and 
(ii) of this section. For combination vending machines, disregard the 
surface area surrounding any refrigerated compartments that are not 
designed to be refrigerated (as demonstrated by the presence of 
temperature controls), whether or not it is transparent. Determine the 
percent transparent surface area on the front side of the beverage 
vending machine as a ratio of the measured transparent area on that side 
divided by the sum of the measured transparent and non-transparent 
areas, multiplying the result by 100.
    (i) Determination of transparent area. Determine the total surface 
area that is transparent as the sum of all surface areas on the front 
side of a beverage vending machine that meet the definition of 
transparent at 10 CFR 431.292. When determining whether or not a 
particular wall segment is transparent, transparency should be 
determined for the aggregate performance of all the materials between 
the refrigerated volume and the ambient environment; the composite 
performance of all those materials in a particular wall segment must 
meet the definition of transparent for that area be treated as 
transparent.
    (ii) Determination of non-transparent area. Determine the total 
surface area that is not transparent as the sum of all surface areas on 
the front side of a beverage vending machine that are not considered 
part of the transparent area, as determined in accordance with paragraph 
(j)(2)(i) of this section.
    (k) Central air conditioners and heat pumps--(1) Verification of 
cooling capacity. The cooling capacity of each tested unit of the 
individual model (for single-package systems) or individual combination 
(for split systems) will be measured pursuant to the test requirements 
of Sec. 430.23(m) of this chapter. The mean of the measurement(s) 
(either the measured cooling capacity for a single unit sample or the 
average of the measured cooling capacities for a multiple unit sample) 
will be used to determine the applicable standards for purposes of 
compliance.
    (2) Verification of CD value. (i) For central air 
conditioners and heat pumps other than models of outdoor units with no 
match, if manufacturers certify that they did not conduct the optional 
tests to determine the Cc and/or Ch value for an individual model (for 
single-package systems) or individual combination (for split systems), 
as applicable, the default Cc and/or Ch value will be used as the basis 
for calculation of SEER or HSPF for each unit tested. If manufacturers 
certify that they conducted the optional tests to determine the Cc and/
or Ch value for an individual model (for single-package systems) or 
individual combination (for split systems), as applicable, the Cc and/or 
Ch value will be measured pursuant to the test requirements of Sec. 
430.23(m) of this chapter for each unit tested and the result for each 
unit tested (either the tested value or the default value, as selected 
according to the criteria for the cyclic test in 10 CFR part 430, 
subpart B, appendix M, section 3.5e) used as the basis for calculation 
of SEER or HSPF for that unit.
    (ii) For models of outdoor units with no match, DOE will use the 
default Cc and/or Ch value pursuant to 10 CFR part 430.
    (l) Miscellaneous refrigeration products--(1) Verification of total 
refrigerated volume. For all miscellaneous refrigeration products, the 
total refrigerated volume of the basic model will be measured pursuant 
to the test requirements of part 430 of this chapter for each unit 
tested. The results of the measurement(s) will be averaged and compared 
to the value of total refrigerated volume certified by the manufacturer. 
The certified total refrigerated volume will be considered valid only 
if:
    (i) The measurement is within two percent, or 0.5 cubic feet (0.2 
cubic feet for products with total refrigerated volume less than 7.75 
cubic feet (220 liters)), whichever is greater, of the certified total 
refrigerated volume; or
    (ii) The measurement is greater than the certified total 
refrigerated volume.
    (A) If the certified total refrigerated volume is found to be valid, 
the certified adjusted total volume will be used as the basis for 
calculating the maximum allowed energy use for the tested basic model.

[[Page 259]]

    (B) If the certified total refrigerated volume is found to be 
invalid, the average measured adjusted total volume, rounded to the 
nearest 0.1 cubic foot, will serve as the basis for calculating the 
maximum allowed energy use for the tested basic model.
    (2) Test for models with two compartments, each having its own user-
operable temperature control. The test described in section 3.3 of the 
applicable test procedure in appendix A to subpart B part 430 of this 
chapter shall be used for all units of a tested basic model before DOE 
makes a determination of noncompliance with respect to the basic model.
    (m) Commercial packaged boilers--(1) Verification of fuel input 
rate. The fuel input rate of each tested unit will be measured pursuant 
to the test requirements of Sec. 431.86 of this chapter. The results of 
the measurement(s) will be compared to the value of rated input 
certified by the manufacturer. The certified rated input will be 
considered valid only if the measurement(s) (either the measured fuel 
input rate for a single unit sample or the average of the measured fuel 
input rates for a multiple unit sample) is within two percent of the 
certified rated input.
    (i) If the measured fuel input rate is within two-percent of the 
certified rated input, the certified rated input will serve as the basis 
for determination of the appropriate equipment class(es) and the mean 
measured fuel input rate will be used as the basis for calculation of 
combustion and/or thermal efficiency for the basic model.
    (ii) If the measured fuel input rate for a gas-fired commercial 
packaged boiler is not within two-percent of the certified rated input, 
DOE will first attempt to increase or decrease the gas manifold pressure 
within the range specified in manufacturer's installation and operation 
manual shipped with the commercial packaged boiler being tested (or, if 
not provided in the manual, in supplemental instructions provided by the 
manufacturer pursuant to Sec. 429.60(b)(4) of this chapter) to achieve 
the certified rated input (within two-percent). If the fuel input rate 
is still not within two-percent of the certified rated input, DOE will 
attempt to increase or decrease the gas inlet pressure within the range 
specified in manufacturer's installation and operation manual shipped 
with the commercial packaged boiler being tested (or, if not provided in 
the manual, in supplemental instructions provided by the manufacturer 
pursuant to Sec. 429.60(b)(4)) to achieve the certified rated input 
(within two-percent). If the fuel input rate is still not within two-
percent of the certified rated input, DOE will attempt to modify the gas 
inlet orifice if the unit is equipped with one. If the fuel input rate 
still is not within two percent of the certified rated input, the mean 
measured fuel input rate (either for a single unit sample or the average 
of the measured fuel input rates for a multiple unit sample) will serve 
as the basis for determination of the appropriate equipment class(es) 
and calculation of combustion and/or thermal efficiency for the basic 
model.
    (iii) If the measured fuel input rate for an oil-fired commercial 
packaged boiler is not within two-percent of the certified rated input, 
the mean measured fuel input rate (either for a single unit sample or 
the average of the measured fuel input rates for a multiple unit sample) 
will serve as the basis for determination of the appropriate equipment 
class(es) and calculation of combustion and/or thermal efficiency for 
the basic model.
    (2) Models capable of producing both hot water and steam. For a 
model of commercial packaged boiler that is capable of producing both 
hot water and steam, DOE may measure the thermal or combustion 
efficiency as applicable (see Sec. 431.87 of this chapter) for steam 
and/or hot water modes. DOE will evaluate compliance based on the 
measured thermal or combustion efficiency in steam and hot water modes, 
independently.
    (n) Commercial water heating equipment other than residential-duty 
commercial water heaters--(1) Verification of fuel input rate. The fuel 
input rate of each tested unit of the basic model will be measured 
pursuant to the test requirements of Sec. 431.106 of this chapter. The 
measured fuel input rate (either the measured fuel input rate for a 
single unit sample or the average of the measured fuel input rates for a 
multiple unit sample) will be compared to the

[[Page 260]]

rated input certified by the manufacturer. The certified rated input 
will be considered valid only if the measured fuel input rate is within 
two percent of the certified rated input.
    (i) If the certified rated input is found to be valid, then the 
certified rated input will serve as the basis for determination of the 
appropriate equipment class and calculation of the standby loss standard 
(as applicable).
    (ii) If the measured fuel input rate for gas-fired commercial water 
heating equipment is not within two percent of the certified rated 
input, DOE will first attempt to increase or decrease the gas outlet 
pressure within 10 percent of the value specified on the nameplate of 
the model of commercial water heating equipment being tested to achieve 
the certified rated input (within 2 percent). If the fuel input rate is 
still not within two percent of the certified rated input, DOE will 
attempt to increase or decrease the gas supply pressure within the range 
specified on the nameplate of the model of commercial water heating 
equipment being tested. If the measured fuel input rate is still not 
within two percent of the certified rated input, DOE will attempt to 
modify the gas inlet orifice, if the unit is equipped with one. If the 
measured fuel input rate still is not within two percent of the 
certified rated input, the measured fuel input rate will serve as the 
basis for determination of the appropriate equipment class and 
calculation of the standby loss standard (as applicable).
    (iii) If the measured fuel input rate for oil-fired commercial water 
heating equipment is not within two percent of the certified rated 
input, the measured fuel input rate will serve as the basis for 
determination of the appropriate equipment class and calculation of the 
standby loss standard (as applicable).
    (2) [Reserved]
    (o) Uninterruptible power supplies. (1) Determine the UPS 
architecture by performing the tests specified in the definitions of VI, 
VFD, and VFI in sections 2.28.1 through 2.28.3 of appendix Y to subpart 
B of 10 CFR part 430.
    (2) [Reserved]
    (p) Compressors--(1) Verification of full-load operating pressure. 
(i) The maximum full-flow operating pressure of each tested unit of the 
basic model will be measured pursuant to the test requirements of 
appendix A to subpart T of part 431 of this chapter, where 90 percent of 
the value of full-load operating pressure certified by the manufacturer 
will be the starting point of the test method prior to increasing 
discharge pressure. The measured maximum full-flow operating pressure 
(either the single measured value for a single unit sample or the mean 
of the measured maximum full-flow operating pressures for a multiple 
unit sample) will be compared to the certified rating for full-load 
operating pressure to determine if the certified rating is valid or not. 
The certified rating for full-load operating pressure will be considered 
valid only if the certified rating for full-load operating pressure is 
less than or equal to the measured maximum full-flow operating pressure 
and greater than or equal to the lesser of--
    (A) 90 percent of the measured maximum full-flow operating pressure; 
or
    (B) 10 psig less than the measured maximum full-flow operating 
pressure.
    (ii) If the certified full-load operating pressure is found to be 
valid, then the certified value will be used as the full-load operating 
pressure and will be the basis for determination of full-load actual 
volume flow rate, pressure ratio at full-load operating pressure, 
specific power, and package isentropic efficiency.
    (iii) If the certified full-load operating pressure is found to be 
invalid, then the measured maximum full-flow operating pressure will be 
used as the full-load operating pressure and will be the basis for 
determination of full-load actual volume flow rate, pressure ratio at 
full-load operating pressure, specific power, and package isentropic 
efficiency.
    (2) Verification of full-load actual volume flow rate. The measured 
full-load actual volume flow rate will be measured, pursuant to the test 
requirements of appendix A to subpart T of part 431 of this chapter, at 
the full-load operating pressure determined in paragraph (p)(1) of this 
section. The certified full-load actual volume flow rate will be 
considered valid only if the measurement(s) (either the measured full-
load actual volume flow rate for a single unit sample or the mean of the

[[Page 261]]

measured values for a multiple unit sample) are within the percentage of 
the certified full-load actual volume flow rate specified in Table 1 of 
this section:

------------------------------------------------------------------------

    (i) If the certified value of full-load actual volume flow rate is 
found to be valid, the full-load actual volume flow rate certified by 
the manufacturer will be used as the basis for determination of the 
applicable standard.
    (ii) If the certified value of full-load actual volume flow rate is 
found to be invalid, the entire sample (one or multiple units) will be 
considered as failing the enforcement test.
    (3) Ancillary equipment. Prior to testing each compressor, DOE will 
install any required ancillary equipment specified by the manufacturer 
in the certification report submitted pursuant to Sec. 429.63(b).
    (q) Walk-in coolers and walk-in freezers. (1) If DOE determines that 
a basic model of a panel, door, or refrigeration system for walk-in 
coolers or walk-in freezers fails to meet an applicable energy 
conservation standard, then the manufacturer of that basic model is 
responsible for the noncompliance. If DOE determines that a complete 
walk-in cooler or walk-in freezer or component thereof fails to meet an 
applicable energy conservation standard, then the manufacturer of that 
walk-in cooler or walk-in freezer is responsible for the noncompliance 
with the applicable standard, except that the manufacturer of a complete 
walk-in cooler or walk-in freezer is not responsible for the use of 
components that were certified and labeled (in accordance with DOE 
labeling requirements) as compliant by another party and later found to 
be noncompliant with the applicable standard(s).
    (2) Verification of refrigeration system net capacity. The net 
capacity of the refrigeration system basic model will be measured 
pursuant to the test requirements of 10 CFR part 431, subpart R, 
appendix C for each unit tested. The results of the measurement(s) will 
be averaged and compared to the value of net capacity certified by the 
manufacturer. The certified net capacity will be considered valid only 
if the average measured net capacity is within plus or minus five 
percent of the certified net capacity.
    (i) If the certified net capacity is found to be valid, the 
certified net capacity will be used as the basis for calculating the 
AWEF of the basic model.
    (ii) If the certified net capacity is found to be invalid, the 
average measured net capacity will serve as the basis for calculating 
the annual energy consumption for the basic model.
    (3) Verification of door surface area. The surface area of a display 
door or non-display door basic model will be measured pursuant to the 
requirements of 10 CFR part 431, subpart R, appendix A for each unit 
tested. The results of the measurement(s) will be averaged and compared 
to the value of the surface area certified by the manufacturer. The 
certified surface area will be considered valid only if the average 
measured surface area is within plus or minus three percent of the 
certified surface area.
    (i) If the certified surface area is found to be valid, the 
certified surface area will be used as the basis for calculating the 
maximum energy consumption (kWh/day) of the basic model.
    (ii) If the certified surface area is found to be invalid, the 
average measured surface area will serve as the basis for calculating 
the maximum energy consumption (kWh/day) of the basic model.
    (4) For each basic model of walk-in cooler and walk-in freezer door, 
DOE will calculate the door's energy consumption using the power listed 
on the nameplate of each electricity consuming device shipped with the 
door. If an electricity consuming device shipped with a walk-in door 
does not have a nameplate or such nameplate does not list the device's 
power, then DOE will use the device's ``rated

[[Page 262]]

power'' included in the door's certification report.

Sec. 429.146  Notice of violation.

    (a) If DOE determines a party has committed a violation of regional 
standards, DOE will issue a Notice of Violation advising that party of 
DOE's determination.
    (b) If, however, DOE determines a noncompliant installation occurred 
in only one instance, the noncompliant installation is remediated prior 
to DOE issuing a Notice of Violation, and the party has no history of 
prior violations, DOE will not issue such notice.
    (c) If DOE does not find a violation of regional standards, DOE will 
notify the party under investigation.

[81 FR 45403, July 14, 2016]



Sec. 429.148  Routine violator.

    (a) DOE will consider, inter alia, the following factors in 
determining if a person is a routine violator: Number of violations in 
current and past cases, length of time over which violations occurred, 
ratio of compliant to noncompliant installations or sales, percentage of 
employees committing violations, evidence of intent, evidence of 
training or education provided, and subsequent remedial actions.
    (b) In the event that DOE determines a person to be a routine 
violator, DOE will issue a Notice of Finding of Routine Violation.
    (c) In making a finding of Routine Violation, DOE will consider 
whether the Routine Violation was limited to a specific location. If DOE 
finds that the routine violation was so limited, DOE may, in its 
discretion, in the Notice of Finding of Routine Violation limit the 
prohibition on manufacturer and/or private labeler sales to a particular 
contractor or distribution location.

Sec. 429.152  Removal of finding of ``routine violator''.

    (a) A routine violator may be removed from DOE's list of routine 
violators through completion of remediation in accordance with the 
requirements in Sec. 429.154.
    (b) A routine violator that wants to remediate must contact the 
Office of the Assistant General Counsel for Enforcement via the point of 
contact listed in the Notice of Finding of Routine Violation and 
identify the distributor(s), manufacturer(s), or private labeler(s) from 
whom it wishes to buy compliant replacement product.
    (c) DOE will contact the distributor(s), manufacturer(s), or private 
labeler(s) and authorize sale of central air conditioner units to the 
routine violator for purposes of remediation within 3 business days of 
receipt of the request for remediation. DOE will provide the 
manufacturer(s), distributor(s), and/or private labeler(s) with an 
official letter authorizing the sale of units for purposes of 
remediation.
    (d) DOE will contact routine violators that requested units for 
remediation within 30 days of sending the official letter to the 
manufacturer(s), distributor(s), and/or private labeler(s) to determine 
the status of the remediation.

the manufacturer and/or private labeler may be fined in accordance with 
Sec. 429.120, for sale of any units to a routine violator during the 
pendency of the appeal that do not meet the applicable regional 
standard.
    (b) If a manufacturer and/or private labeler has knowledge of 
routine violation, then the manufacturer can be held liable for all 
sales that occurred after the date the manufacturer had knowledge of the 
routine violation. However, if the manufacturer and/or private labeler 
reports its suspicion of

[[Page 265]]

a routine violation to DOE within 15 days of receipt of such knowledge, 
then it will not be liable for product sold to the suspected routine 
violator prior to reporting the routine violation to DOE.

Sec. 429.158  Product determined noncompliant with regional standards.

    (a) If DOE determines a model of outdoor unit fails to meet the 
applicable regional standard(s) when tested in a combination certified 
by the same manufacturer, then the outdoor unit basic model will be 
deemed noncompliant with the regional standard(s). In accordance with 
Sec. 429.102(c), the outdoor unit manufacturer and/or private labeler 
is liable for distribution of noncompliant units in commerce.
    (b) If DOE determines a combination fails to meet the applicable 
regional standard(s) when tested in a combination certified by a 
manufacturer other than the outdoor unit manufacturer (e.g., ICM), then 
that combination is deemed noncompliant with the regional standard(s). 
In accordance with Sec. 429.102(c), the certifying manufacturer is 
liable for distribution of noncompliant units in commerce.
    (c) All such units manufactured and distributed in commerce are 
presumed to have been installed in a region where they would not comply 
with the applicable energy conservation standard; however, a 
manufacturer and/or private labeler may demonstrate through installer 
records that individual units were installed in a region where the unit 
is compliant with the applicable standards.

Sec. Appendix A to Subpart C of Part 429--Sampling Plan for
Enforcement Testing of Covered Consumer Products and Certain 
High-Volume Commercial Equipment

    (a) The first sample size (n1) for enforcement testing 
must be four or more units, except as provided by Sec. 429.57(e)(1)(i).
    (b) Compute the mean of the measured energy performance 
(x1) for all tests as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.132

where xi is the measured energy or water efficiency or 
          consumption from test i, and n1 is the total number 
          of tests.

    (c) Compute the standard deviation (s1) of the measured 
energy performance from the n1 tests as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.133

    (d) Compute the standard error (sx1) of the measured 
energy performance from the n1 tests as follows:

[[Page 266]]

[GRAPHIC] [TIFF OMITTED] TR07MR11.134

    (e)(1) Compute the upper control limit (UCL1) and lower 
control limit (LCL1) for the mean of the first sample using 
the applicable DOE energy efficiency standard (EES) as the desired mean 
and a probability level of 95 percent (two-tailed test) as follows:

LCL1 EES -- ts X1 X
[GRAPHIC] [TIFF OMITTED] TR07MR11.135

where t is the statistic based on a 95 percent two-tailed probability 
          level with degrees of freedom (n1-1).

    (2) For an energy efficiency or water efficiency standard, compare 
the mean of the first sample (x1) with the upper and lower 
control limits (UCL1 and LCL1) to determine one of 
the following:
    (i) If the mean of the first sample is below the lower control 
limit, then the basic model is in noncompliance and testing is at an 
end. (Do not go on to any of the steps below.)
    (ii) If the mean of the first sample is equal to or greater than the 
upper control limit, then the basic model is in compliance and testing 
is at an end. (Do not go on to any of the steps below.)
    (iii) If the sample mean is equal to or greater than the lower 
control limit but less than the upper control limit, then no 
determination of compliance or noncompliance can be made and a second 
sample size is determined by Step (e)(3).
    (3) For an energy efficiency or water efficiency standard, determine 
the second sample size (n2) as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.136

where s1 and t have the values used in equations 2 and 4, 
          respectively. The term ``0.05 EES'' is the difference between 
          the applicable energy efficiency or water efficiency standard 
          and 95 percent of the standard, where 95 percent of the 
          standard is taken as the lower control limit. This procedure 
          yields a sufficient combined sample size (n1 + 
          n2) to give an estimated 97.5 percent probability 
          of obtaining a determination of compliance when the true mean 
          efficiency is equal to the applicable standard. Given the 
          solution value of n2, determine one of the 
          following:

    (i) If the value of n2 is less than or equal to zero and 
if the mean energy or water efficiency of the first sample 
(x1) is either equal to or greater than the lower control 
limit (LCL1) or equal to or greater than 95 percent of the 
applicable energy efficiency or water efficiency standard (EES), 
whichever is greater, i.e., if n2<=0 and 
x1=max (LCL1, 0.95 EES), the basic 
model is in compliance and testing is at an end.
    (ii) If the value of n2 is less than or equal to zero and 
the mean energy efficiency of the first sample (x1) is less 
than the lower control limit (LCL1) or less than 95 percent 
of the applicable energy or water efficiency standard (EES), whichever 
is greater, i.e., if n2<=0 and x1<=max 
(LCL1, 0.95 EES), the basic model is not in compliance and 
testing is at an end.
    (iii) If the value of n2 is greater than zero, then, the 
value of the second sample size is determined to be the smallest integer 
equal to or greater than the solution value of n2 for 
equation (6). If the value of n2 so calculated is greater 
than 21- n1, set n2 equal to 21- n1.
    (4) Compute the combined mean (x2) of the measured energy 
or water efficiency of the n1 and n2 units of the 
combined first and second samples as follows:

[[Page 267]]

[GRAPHIC] [TIFF OMITTED] TR07MR11.137

    (5) Compute the standard error (Sx2) of the measured 
energy or water performance of the n1 and n2 units 
in the combined first and second samples as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.138

    Note: s1 is the value obtained in Step (c).
    (6) For an energy efficiency standard (EES), compute the lower 
control limit (LCL2) for the mean of the combined first and 
second samples using the DOE EES as the desired mean and a one-tailed 
probability level of 97.5 percent (equivalent to the two-tailed 
probability level of 95 percent used in Step (e)(1)) as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.139

where the t-statistic has the value obtained in Step (e)(1) and 
sx2 is the value obtained in Step (e)(5).

    (7) For an energy efficiency standard (EES), compare the combined 
sample mean (x2) to the lower control limit (LCL2) 
to determine one of the following:
    (i) If the mean of the combined sample (x2) is less than 
the lower control limit (LCL2) or 95 percent of the 
applicable energy efficiency standard (EES), whichever is greater, i.e., 
if x22, 0.95 EES), the basic model is not 
compliant and testing is at an end.
    (iii) If the mean of the combined sample (x2) is equal to 
or greater than the lower control limit (LCL2) or 95 percent 
of the applicable energy efficiency standard (EES), whichever is 
greater, i.e., if x2=max (LCL2, 0.95 
EES), the basic model is in compliance and testing is at an end.
    (f)(1) Compute the upper control limit (UCL1) and lower 
control limit (LCL1) for the mean of the first sample using 
the applicable DOE energy consumption standard (ECS) as the desired mean 
and a probability level of 95 percent (two-tailed test) as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.140

where t is the statistic based on a 95 percent two-tailed probability 
level with degrees of freedom (n1 - 1).

    (2) For an energy or water consumption standard, compare the mean of 
the first sample (x1) with the upper and lower control limits 
(UCL1 and LCL1) to determine one of the following:
    (i) If the mean of the first sample is above the upper control 
limit, then the basic model is in noncompliance and testing is at an 
end. (Do not go on to any of the steps below.)
    (ii) If the mean of the first sample is equal to or less than the 
lower control limit, then the basic model is in compliance and testing 
is at an end. (Do not go on to any of the steps below.)
    (iii) If the sample mean is equal to or less than the upper control 
limit but greater than the lower control limit, then no determination of 
compliance or noncompliance can be made and a second sample size is 
determined by Step (f)(3).
    (3) For an Energy or Water Consumption Standard, determine the 
second sample size (n2) as follows:

[[Page 268]]

[GRAPHIC] [TIFF OMITTED] TR07MR11.141

where s1and t have the values used in equations (2) and (10), 
respectively. The term ``0.05 ECS'' is the difference between the 
applicable energy or water consumption standard and 105 percent of the 
standard, where 105 percent of the standard is taken as the upper 
control limit. This procedure yields a sufficient combined sample size 
(n1 + n2) to give an estimated 97.5 percent 
probability of obtaining a determination of compliance when the true 
mean consumption is equal to the applicable standard. Given the solution 
value of n2, determine one of the following:

    (i) If the value of n2 is less than or equal to zero and 
if the mean energy or water consumption of the first sample 
(x1) is either equal to or less than the upper control limit 
(UCL1) or equal to or less than 105 percent of the applicable 
energy or water consumption standard (ECS), whichever is less, i.e., if 
n2 <=0 and x1 <=min (UCL1, 1.05 ECS), 
the basic model is in compliance and testing is at an end.
    (ii) If the value of n2 is less than or equal to zero and 
the mean energy or water consumption of the first sample (x1) 
is greater than the upper control limit (UCL1) or more than 
105 percent of the applicable energy or water consumption standard 
(ECS), whichever is less, i.e., if n2 <=0 and x1 
min (UCL1, 1.05 EPS), the basic model is not 
compliant and testing is at an end.
    (iii) If the value of n2 is greater than zero, then the 
value of the second sample size is determined to be the smallest integer 
equal to or greater than the solution value of n2 for 
equation (11). If the value of n2 so calculated is greater 
than 21-n1, set n2 equal to 21-n1.
    (4) Compute the combined mean (x2) of the measured energy 
or water consumption of the n1 and n2 units of the 
combined first and second samples as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.142

    (5) Compute the standard error (Sx2) of the measured 
energy or water consumption of the n1 and n2 units 
in the combined first and second samples as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.143

    Note: s1 is the value obtained in Step (c).
    (6) For an energy or water consumption standard (ECS), compute the 
upper control limit (UCL2) for the mean of the combined first 
and second samples using the DOE ECS as the desired mean and a one-
tailed probability level of 97.5 percent (equivalent to the two-tailed 
probability level of 95 percent used in Step (f)(1)) as follows:
[GRAPHIC] [TIFF OMITTED] TR07MR11.144

where the t-statistic has the value obtained in (f)(1).
    (7) For an energy or water consumption standard (ECS), compare the 
combined sample mean (x2) to the upper control limit 
(UCL2) to determine one of the following:
    (i) If the mean of the combined sample (x2) is greater 
than the upper control limit (UCL2) or 105 percent of the ECS 
whichever is less, i.e., if x2 min 
(UCL2, 1.05 ECS), the basic model is not compliant and 
testing is at an end.

[[Page 269]]

    (ii) If the mean of the combined sample (x2) is equal to 
or less than the upper control limit (UCL2) or 105 percent of 
the applicable energy or water performance standard (ECS), whichever is 
less, i.e., if x 2<=min (UCL2, 1.05 ECS), the 
basic model is in compliance and testing is at an end.

Sec. 430.5  Error correction procedures for energy conservation
standards rules.

    (a) Scope and purpose. The regulations in this section describe 
procedures

[[Page 307]]

through which the Department of Energy accepts and considers submissions 
regarding possible Errors in its rules under the Energy Policy and 
Conservation Act, as amended (42 U.S.C. 6291-6317). This section applies 
to rules establishing or amending energy conservation standards under 
the Act, except that this section does not apply to direct final rules 
issued pursuant to section 325(p)(4) of the Act (42 U.S.C. 6295(p)(4)).
    (b) Definitions.
    Act means the Energy Policy and Conservation Act of 1975, as amended 
(42 U.S.C. 6291-6317).
    Error means an aspect of the regulatory text of a rule that is 
inconsistent with what the Secretary intended regarding the rule at the 
time of posting. Examples of possible mistakes that might give rise to 
Errors include:
    (i) A typographical mistake that causes the regulatory text to 
differ from how the preamble to the rule describes the rule;
    (ii) A calculation mistake that causes the numerical value of an 
energy conservation standard to differ from what technical support 
documents would justify; or

                        Subpart B_Test Procedures



Sec. 430.21  Purpose and scope.

    This subpart contains test procedures required to be prescribed by 
DOE pursuant to section 323 of the Act.



Sec. 430.23  Test procedures for the measurement of energy and
water consumption.

    When the test procedures of this section call for rounding off of 
test results, and the results fall equally between two values of the 
nearest dollar, kilowatt-hour, or other specified nearest value, the 
result shall be rounded up to the nearest higher value.
    (a) Refrigerators and refrigerator-freezers. (1) The estimated 
annual operating cost for models without an anti-sweat heater switch 
shall be the product of the following three factors, with the resulting 
product then being rounded to the nearest dollar per year:

    (ii) The average per-cycle energy consumption for the standard cycle 
in kilowatt-hours per cycle, determined according to section 6.2 of 
appendix A of this subpart; and

per kilowatt-hour as provided by the Secretary.
    (2) The estimated annual operating cost for models with an anti-
sweat heater switch shall be the product of the following three factors, 
with the resulting product then being rounded to the nearest dollar per 
year:

[[Page 309]]

    (i) The representative average-use cycle of 365 cycles per year;
    (ii) Half the sum of the average per-cycle energy consumption for 
the standard cycle and the average per-cycle energy consumption for a 
test cycle type with the anti-sweat heater switch in the position set at 
the factory just before shipping, each in kilowatt-hours per cycle, 
determined according to section 6.2 of appendix A of this subpart; and
    (iii) The representative average unit cost of electricity in dollars 
per kilowatt-hour as provided by the Secretary.
    (3) The estimated annual operating cost for any other specified 
cycle type shall be the product of the following three factors, the 
resulting product then being rounded to the nearest dollar per year:
    (i) The representative average-use cycle of 365 cycles per year;
    (ii) The average per-cycle energy consumption for the specified 
cycle type, determined according to section 6.2 of appendix A of this 
subpart; and
    (iii) The representative average unit cost of electricity in dollars 
per kilowatt-hour as provided by the Secretary.
    (4) The energy factor, expressed in cubic feet per kilowatt-hour per 
cycle, shall be:
    (i) For models without an anti-sweat heater switch, the quotient of:
    (A) The adjusted total volume in cubic feet, determined according to 
section 6.1 of appendix A of this subpart, divided by--
    (B) The average per-cycle energy consumption for the standard cycle 
in kilowatt-hours per cycle, determined according to section 6.2 of 
appendix A of this subpart, the resulting quotient then being rounded to 
the second decimal place; and
    (ii) For models having an anti-sweat heater switch, the quotient of:
    (A) The adjusted total volume in cubic feet, determined according to 
6.1 of appendix A of this subpart, divided by--
    (B) Half the sum of the average per-cycle energy consumption for the 
standard cycle and the average per-cycle energy consumption for a test 
cycle type with the anti-sweat heater switch in the position set at the 
factory just before shipping, each in kilowatt-hours per cycle, 
determined according to section 6.2 of appendix A of this subpart, the 
resulting quotient then being rounded to the second decimal place.
    (5) The annual energy use, expressed in kilowatt-hours per year, 
shall be the following, rounded to the nearest kilowatt-hour per year:
    (i) For models without an anti-sweat heater switch, the 
representative average use cycle of 365 cycles per year multiplied by 
the average per-cycle energy consumption for the standard cycle in 
kilowatt-hours per cycle, determined according to section 6.2 of 
appendix A of this subpart; and

determined according to section 6.2 of appendix A of this subpart.
    (6) Other useful measures of energy consumption shall be those 
measures of energy consumption that the Secretary determines are likely 
to assist consumers in making purchasing decisions which are derived 
from the application of appendix A of this subpart.
    (7) The following principles of interpretation shall be applied to 
the test procedure. The intent of the energy test procedure is to 
simulate typical room conditions (72 [deg]F (22.2 [deg]C)) with door 
openings, by testing at 90 [deg]F (32.2 [deg]C) without door openings. 
Except for operating characteristics that are affected by ambient 
temperature (for example, compressor percent run time), the unit, when 
tested under this test procedure, shall operate in a manner equivalent 
to the unit's operation while in typical room conditions.
    (i) The energy used by the unit shall be calculated when a 
calculation is provided by the test procedure. Energy consuming 
components that operate in typical room conditions (including as a 
result of door openings, or a function of

[[Page 310]]

humidity), and that are not excluded by this test procedure, shall 
operate in an equivalent manner during energy testing under this test 
procedure, or be accounted for by all calculations as provided for in 
the test procedure. Examples:
    (A) Energy saving features that are designed to operate when there 
are no door openings for long periods of time shall not be functional 
during the energy test.
    (B) The defrost heater shall neither function nor turn off 
differently during the energy test than it would when in typical room 
conditions. Also, the product shall not recover differently during the 
defrost recovery period than it would in typical room conditions.
    (C) Electric heaters that would normally operate at typical room 
conditions with door openings shall also operate during the energy test.
    (D) Energy used during adaptive defrost shall continue to be 
measured and adjusted per the calculation provided in this test 
procedure.
    (ii) DOE recognizes that there may be situations that the test 
procedures do not completely address. In such cases, a manufacturer must 
obtain a waiver in accordance with the relevant provisions of 10 CFR 
part 430 if:
    (A) A product contains energy consuming components that operate 
differently during the prescribed testing than they would during 
representative average consumer use; and
    (B) Applying the prescribed test to that product would evaluate it 
in a manner that is unrepresentative of its true energy consumption 
(thereby providing materially inaccurate comparative data).
    (b) Freezers. (1) The estimated annual operating cost for freezers 
without an anti-sweat heater switch shall be the product of the 
following three factors, with the resulting product then being rounded 
to the nearest dollar per year:
    (i) The representative average-use cycle of 365 cycles per year;
    (ii) The average per-cycle energy consumption for the standard cycle 
in kilowatt-hours per cycle, determined according to section 6.2 of 
appendix B of this subpart; and
    (iii) The representative average unit cost of electricity in dollars 
per kilowatt-hour as provided by the Secretary.

    (ii) Half the sum of the average per-cycle energy consumption for 
the standard cycle and the average per-cycle energy consumption for a 
test cycle type with the anti-sweat heater switch in the position set at 
the factory just before shipping, each in kilowatt-hours per cycle, 
determined according to section 6.2 of appendix B of this subpart; and
    (iii) The representative average unit cost of electricity in dollars 
per kilowatt-hour as provided by the Secretary.
    (3) The estimated annual operating cost for any other specified 
cycle type for freezers shall be the product of the following three 
factors, with the resulting product then being rounded to the nearest 
dollar per year:
    (i) The representative average-use cycle of 365 cycles per year;
    (ii) The average per-cycle energy consumption for the specified 
cycle type, determined according to section 6.2 of appendix B of this 
subpart; and
    (iii) The representative average unit cost of electricity in dollars 
per kilowatt-hour as provided by the Secretary.
    (4) The energy factor for freezers, expressed in cubic feet per 
kilowatt-hour per cycle, shall be:
    (i) For freezers not having an anti-sweat heater switch, the 
quotient of:
    (A) The adjusted net refrigerated volume in cubic feet, determined 
according to section 6.1 of appendix B of this subpart, divided by--
    (B) The average per-cycle energy consumption for the standard cycle 
in kilowatt-hours per cycle, determined according to 6.2 of appendix B 
of this subpart, with the resulting quotient then being rounded to the 
second decimal place; and
    (ii) For freezers having an anti-sweat heater switch, the quotient 
of:

[[Page 311]]

    (A) The adjusted net refrigerated volume in cubic feet, determined 
according to section 6.1 of appendix B of this subpart, divided by--
    (B) Half the sum of the average per-cycle energy consumption for the 
standard cycle and the average per-cycle energy consumption for a test 
cycle type with the anti-sweat heater switch in the position set at the 
factory just before shipping, each in kilowatt-hours per cycle, 
determined according to section 6.2 of appendix B of this subpart, with 
the resulting quotient then being rounded to the second decimal place.
    (5) The annual energy use of all freezers, expressed in kilowatt-
hours per year, shall be the following, rounded to the nearest kilowatt-
hour per year:
    (i) For freezers not having an anti-sweat heater switch, the 
representative average use cycle of 365 cycles per year multiplied by 
the average per-cycle energy consumption for the standard cycle in 
kilowatt-hours per cycle, determined according to section 6.2 of 
appendix B of this subpart; and
    (ii) For freezers having an anti-sweat heater switch, the 
representative average use cycle of 365 cycles per year multiplied by 
half the sum of the average per-cycle energy consumption for the 
standard cycle and the average per-cycle energy consumption for a test 
cycle type with the anti-sweat heater switch in the position set at the 
factory just before shipping, each in kilowatt-hours per cycle, 
determined according to section 6.2 of appendix B of this subpart.
    (6) Other useful measures of energy consumption for freezers shall 
be those measures the Secretary determines are likely to assist 
consumers in making purchasing decisions and are derived from the 
application of appendix B of this subpart.
    (7) The following principles of interpretation shall be applied to 
the test procedure. The intent of the energy test procedure is to 
simulate typical room conditions (72 [deg]F (22.2 [deg]C)) with door 
openings by testing at 90 [deg]F (32.2 [deg]C) without door openings. 
Except for operating characteristics that are affected by ambient 
temperature (for example, compressor percent run time), the unit, when

during the energy test.
    (B) The defrost heater shall neither function nor turn off 
differently during the energy test than it would when in typical room 
conditions. Also, the product shall not recover differently during the

    (C) Electric heaters that would normally operate at typical room 
conditions with door openings shall also operate during the energy test.
    (D) Energy used during adaptive defrost shall continue to be 
measured and adjusted per the calculation provided for in this test 
procedure.
    (ii) DOE recognizes that there may be situations that the test 
procedures do not completely address. In such cases, a manufacturer must 
obtain a waiver in accordance with the relevant provisions of this part 
if:
    (A) A product contains energy consuming components that operate 
differently during the prescribed testing than they would during 
representative average consumer use; and
    (B) Applying the prescribed test to that product would evaluate it 
in a manner that is unrepresentative of its true energy consumption 
(thereby providing materially inaccurate comparative data).

[[Page 324]]

    (6) Other useful measures of energy consumption shall be those 
measures of energy consumption that the Secretary determines are likely 
to assist consumers in making purchasing decisions which are derived 
from the application of appendix A of this subpart.
    (7) The following principles of interpretation shall be applied to 
the test procedure. The intent of the energy test procedure is to 
simulate operation in typical room conditions (72 [deg]F (22.2 [deg]C)) 
with door openings by testing at 90 [deg]F (32.2 [deg]C) ambient 
temperature without door openings. Except for operating characteristics 
that are affected by ambient temperature (for example, compressor 
percent run time), the unit, when tested under this test procedure, 
shall operate in a manner equivalent to the unit's operation while in 
typical room conditions.
    (i) The energy used by the unit shall be calculated when a 
calculation is provided by the test procedure. Energy consuming 
components that operate in typical room conditions (including as a 
result of door openings, or a function of humidity), and that are not 
excluded by this test procedure, shall operate in an equivalent manner 
during energy testing under this test procedure, or be accounted for by 
all calculations as provided for in the test procedure. Examples:
    (A) Energy saving features that are designed to operate when there 
are no door openings for long periods of time shall not be functional 
during the energy test.
    (B) The defrost heater shall neither function nor turn off 
differently during the energy test than it would when in typical room 
conditions. Also, the product shall not recover differently during the 
defrost recovery period than it would in typical room conditions.
    (C) Electric heaters that would normally operate at typical room 
conditions with door openings shall also operate during the energy test.
    (D) Energy used during adaptive defrost shall continue to be 
measured and adjusted per the calculation provided for in this test 
procedure.
    (ii) DOE recognizes that there may be situations that the test 
procedures do not completely address. In such cases, a manufacturer must 
obtain a waiver in accordance with the relevant provisions of this part 
if:
    (A) A product contains energy consuming components that operate 
differently during the prescribed testing than they would during 
representative average consumer use; and
    (B) Applying the prescribed test to that product would evaluate it 
in a manner that is unrepresentative of its true energy consumption 
(thereby providing materially inaccurate comparative data).
    (8) For non-compressor models, ``compressor'' and ``compressor 
cycles'' as used in appendix A of this subpart shall be interpreted to 
mean ``refrigeration system'' and ``refrigeration system cycles,'' 
respectively.
    (gg) General Service Lamps. (1) For general service incandescent 
lamps, use paragraph (r) of this section.
    (2) For compact fluorescent lamps, use paragraph (y) of this 
section.
    (3) For integrated LED lamps, use paragraph (ee) of this section.
    (4) For other incandescent lamps, measure initial light output, 
input power, lamp efficacy, power factor, and standby mode power in 
accordance with appendix DD of this subpart.
    (5) For other fluorescent lamps, measure initial light output, input 
power, lamp efficacy, power factor, and standby mode power in accordance 
with appendix DD of this subpart.
    (6) For OLED and non-integrated LED lamps, measure initial light 
output, input power, lamp efficacy, power factor, and standby mode power 
in accordance with appendix DD of this subpart.

Sec. 430.27  Petitions for waiver and interim waiver.

    (a) General information. This section provides a means for seeking 
waivers of the test procedure requirements of this subpart for basic 
models that meet the requirements of paragraph (a)(1) of this section. 
In granting a waiver or interim waiver, DOE will not change the energy 
use or efficiency metric that the manufacturer must use to certify 
compliance with the applicable energy conservation standard and to make 
representations about the energy use or efficiency of the covered 
product. The granting of a waiver or interim waiver by DOE does not 
exempt such basic models from any other regulatory requirement contained 
in this part or the certification and compliance requirements of 10 CFR 
part 429 and specifies an alternative method for testing the basic 
models addressed in the waiver.
    (1) Any interested person may submit a petition to waive for a 
particular basic model any requirements of Sec. 430.23 or of any 
appendix to this subpart, upon the grounds that the basic model contains 
one or more design characteristics which either prevent testing of the 
basic model according to the prescribed test procedures or cause the 
prescribed test procedures to evaluate the basic model in a manner so 
unrepresentative of its true energy and/or water consumption 
characteristics as to provide materially inaccurate comparative data.
    (2) Manufacturers of basic model(s) subject to a waiver or interim 
waiver are responsible for complying with the other requirements of this 
subpart and with the requirements of 10 CFR part 429 regardless of the 
person that originally submitted the petition for waiver and/or interim 
waiver. The filing of a petition for waiver and/or interim waiver shall 
not constitute grounds for noncompliance with any requirements of this 
subpart.
    (3) All correspondence regarding waivers and interim waivers must be 
submitted to DOE either electronically to [email protected] 
(preferred method of transmittal) or by mail to U.S. Department of 
Energy, Building Technologies Program, Test Procedure Waiver, 1000 
Independence Avenue SW., Mailstop EE-5B, Washington, DC 20585-0121.
    (b) Petition content and publication. (1) Each petition for waiver 
must:
    (i) Identify the particular basic model(s) for which a waiver is 
requested, each brand name under which the identified basic model(s) 
will be distributed in commerce, the design characteristic(s) 
constituting the grounds for the petition, and the specific requirements 
sought to be waived, and must discuss in detail the need for the 
requested waiver;
    (ii) Identify manufacturers of all other basic models distributed in 
commerce in the United States and known to the petitioner to incorporate 
design characteristic(s) similar to those found in the basic model that 
is the subject of the petition;
    (iii) Include any alternate test procedures known to the petitioner 
to evaluate the performance of the product type in a manner 
representative of the energy and/or water consumption characteristics of 
the basic model; and
    (iv) Be signed by the petitioner or an authorized representative. In 
accordance with the provisions set forth in 10 CFR 1004.11, any request 
for confidential treatment of any information contained in a petition 
for waiver or in supporting documentation must be accompanied by a copy 
of the petition, application or supporting documentation from which the 
information claimed to be confidential has been deleted. DOE will 
publish in the Federal Register the petition and supporting documents 
from which confidential information, as determined by DOE, has been 
deleted in accordance with 10 CFR 1004.11 and will solicit comments, 
data

[[Page 326]]

and information with respect to the determination of the petition.
    (2) Each petition for interim waiver must reference the related 
petition for waiver by identifying the particular basic model(s) for 
which a waiver is being sought. Each petition for interim waiver must 
demonstrate likely success of the petition for waiver and address what 
economic hardship and/or competitive disadvantage is likely to result 
absent a favorable determination on the petition for interim waiver. 
Each petition for interim waiver must be signed by the petitioner or an 
authorized representative.
    (c) Notification to other manufacturers. (1) Each petitioner for 
interim waiver must, upon publication of a grant of an interim waiver in 
the Federal Register, notify in writing all known manufacturers of 
domestically marketed basic models of the same product class (as 
specified in 10 CFR 430.32) and of other product classes known to the 
petitioner to use the technology or have the characteristic at issue in 
the waiver. The notice must include a statement that DOE has published 
the interim waiver and petition for waiver in the Federal Register and 
the date the petition for waiver was published. The notice must also 
include a statement that DOE will receive and consider timely written 
comments on the petition for waiver. Within five working days, each 
petitioner must file with DOE a statement certifying the names and 
addresses of each person to whom a notice of the petition for waiver has 
been sent.
    (2) If a petitioner does not request an interim waiver and 
notification has not been provided pursuant to paragraph (c)(1) of this 
section, each petitioner, after filing a petition for waiver with DOE, 
and after the petition for waiver has been published in the Federal 
Register, must, within five working days of such publication, notify in 
writing all known manufacturers of domestically marketed units of the 
same product class (as listed in 10 CFR 430.32) and of other product 
classes known to the petitioner to use the technology or have the 
characteristic at issue in the waiver. The notice must include a 
statement that DOE has published the petition in the Federal Register 
and the date the petition for waiver was published. Within five working 
days of the publication of the petition in the Federal Register, each 
petitioner must file with DOE a statement certifying the names and 
addresses of each person to whom a notice of the petition for waiver has 
been sent.
    (d) Public comment and rebuttal. (1) Any person submitting written 
comments to DOE with respect to an interim waiver must also send a copy 
of the comments to the petitioner by the deadline specified in the 
notice.
    (2) Any person submitting written comments to DOE with respect to a 
petition for waiver must also send a copy of such comments to the 
petitioner.
    (3) A petitioner may, within 10 working days of the close of the 
comment period specified in the Federal Register, submit a rebuttal 
statement to DOE. A petitioner may rebut more than one comment in a 
single rebuttal statement.
    (e) Provisions specific to interim waivers--(1) Disposition of 
application. If administratively feasible, DOE will notify the applicant 
in writing of the disposition of the petition for interim waiver within 
30 business days of receipt of the application. Notice of DOE's 
determination on the petition for interim waiver will be published in 
the Federal Register.
    (2) Criteria for granting. DOE will grant an interim waiver from the 
test procedure requirements if it appears likely that the petition for 
waiver will be granted and/or if DOE determines that it would be 
desirable for public policy reasons to grant immediate relief pending a 
determination on the petition for waiver.
    (f) Provisions specific to waivers--(1) Disposition of application. 
The petitioner shall be notified in writing as soon as practicable of 
the disposition of each petition for waiver. DOE shall issue a decision 
on the petition as soon as is practicable following receipt and review 
of the Petition for Waiver and other applicable documents, including, 
but not limited to, comments and rebuttal statements.
    (2) Criteria for granting. DOE will grant a waiver from the test 
procedure requirements if DOE determines either

[[Page 327]]

that the basic model(s) for which the waiver was requested contains a 
design characteristic that prevents testing of the basic model according 
to the prescribed test procedures, or that the prescribed test 
procedures evaluate the basic model in a manner so unrepresentative of 
its true energy or water consumption characteristics as to provide 
materially inaccurate comparative data. Waivers may be granted subject 
to conditions, which may include adherence to alternate test procedures 
specified by DOE. DOE will consult with the Federal Trade Commission 
prior to granting any waiver, and will promptly publish in the Federal 
Register notice of each waiver granted or denied, and any limiting 
conditions of each waiver granted.
    (g) Extension to additional basic models. A petitioner may request 
that DOE extend the scope of a waiver or an interim waiver to include 
additional basic models employing the same technology as the basic 
model(s) set forth in the original petition. DOE will publish any such 
extension in the Federal Register.
    (h) Duration. (1) Within one year of issuance of an interim waiver, 
DOE will either:
    (i) Publish in the Federal Register a determination on the petition 
for waiver; or
    (ii) Publish in the Federal Register a new or amended test procedure 
that addresses the issues presented in the waiver.
    (2) When DOE amends the test procedure to address the issues 
presented in a waiver, the waiver will automatically terminate on the 
date on which use of that test procedure is required to demonstrate 
compliance.
    (i) Compliance certification. (1) If the alternate test procedure 
specified in the interim waiver differs from the alternate test 
procedure specified by DOE in a subsequent decision and order granting 
the petition for waiver, a manufacturer who has already certified basic 
models using the procedure permitted in DOE's grant of an interim test 
procedure waiver is not required to re-test and re-rate those basic 
models so long as: The manufacturer used that alternative procedure to 
certify the compliance of the basic model after DOE granted the 
company's interim waiver request; changes have not been made to those 
basic models that would cause them to use more energy or otherwise be 
less energy efficient; and the manufacturer does not modify the 
certified rating. However, if the alternate test procedure specified in 
the interim waiver differs from the alternate test procedure specified 
by DOE in a subsequent decision and order granting the petition for 
waiver and if specified by DOE in the decision and order, the 
manufacturer must re-test and re-certify compliance using the procedure 
specified by DOE in the decision and order by the time of the next 
annual certification.
    (2) After DOE publishes a decision and order in the Federal 
Register, a manufacturer must use the test procedure contained in that 
notice to rate any basic models covered by the waiver that have not yet 
been certified to DOE and for any future testing in support of the 
certification for the basic model(s) while the waiver is valid.
    (j) Petition for waiver required of other manufacturers. Within 60 
days after DOE issues a waiver to a manufacturer for a product employing 
a particular technology or having a particular characteristic, any 
manufacturer currently distributing in commerce in the United States a 
product employing a technology or characteristic that results in the 
same need for a waiver (as specified by DOE in the published decision 
and order on the petition in the Federal Register) must submit a 
petition for waiver pursuant to the requirements of this section. 
Manufacturers not currently distributing such products in commerce in 
the United States must petition for and be granted a waiver prior to 
distribution in commerce in the United States. Manufacturers may also 
submit a request for interim waiver pursuant to the requirements of this 
section.
    (k) Rescission or modification. (1) DOE may rescind or modify a 
waiver or interim waiver at any time upon DOE's determination that the 
factual basis underlying the petition for waiver or interim waiver is 
incorrect, or upon a determination that the results from the alternate 
test procedure are unrepresentative of the basic model(s)' true

[[Page 328]]

energy consumption characteristics. Waivers and interim waivers are 
conditioned upon the validity of statements, representations, and 
documents provided by the requestor; any evidence that the original 
grant of a waiver or interim waiver was based upon inaccurate 
information will weigh against continuation of the waiver. DOE's 
decision will specify the basis for its determination and, in the case 
of a modification, will also specify the change to the authorized test 
procedure.
    (2) A person may request that DOE rescind or modify a waiver or 
interim waiver issued to that person if the person discovers an error in 
the information provided to DOE as part of its petition, determines that 
the waiver is no longer needed, or for other appropriate reasons. In a 
request for rescission, the requestor must provide a statement 
explaining why it is requesting rescission. In a request for 
modification, the requestor must explain the need for modification to 
the authorized test procedure and detail the modifications needed and 
the corresponding impact on measured energy consumption.
    (3) DOE will publish a proposed rescission or modification (DOE-
initiated or at the request of the original requestor) in the Federal 
Register for public comment. A requestor may, within 10 working days of 
the close of the comment period specified in the proposed rescission or 
modification published in the Federal Register, submit a rebuttal 
statement to DOE. A requestor may rebut more than one comment in a 
single rebuttal statement.
    (4) DOE will publish its decision in the Federal Register. DOE's 
determination will be based on relevant information contained in the 
record and any comments received.
    (5) After the effective date of a rescission, any basic model(s) 
previously subject to a waiver must be tested and certified using the 
applicable DOE test procedure in 10 CFR part 430.
    (l) Revision of regulation. As soon as practicable after the 
granting of any waiver, DOE will publish in the Federal Register a 
notice of proposed rulemaking to amend its regulations so as to 
eliminate any need for the continuation of such waiver. As soon 
thereafter as practicable, DOE will publish in the Federal Register a 
final rule.
    (m) To exhaust administrative remedies, any person aggrieved by an 
action under this section must file an appeal with the DOE's Office of 
Hearings and Appeals as provided in 10 CFR part 1003, subpart C.

   Sec. Appendix A to Subpart B of Part 430--Uniform Test Method for 
    Measuring the Energy Consumption of Refrigerators, Refrigerator-
           Freezers, and Miscellaneous Refrigeration Products

    Note: For refrigerators and refrigerator-freezers, the rounding 
requirements specified in sections 5.3.e and 6.1 of this appendix are 
not required for use until the compliance date of any amended energy 
conservation standards for these products. For combination cooler 
refrigeration products, manufacturers must use the test procedures in 
this appendix for all representations of energy use starting on the 
compliance date of any energy conservation standards for these products. 
For all other miscellaneous refrigeration products (e.g. coolers), 
manufacturers must use the test procedures in this appendix for all 
representations of energy use on or after January 17, 2017.

                             1. Definitions

    Section 3, Definitions, of HRF-1-2008 (incorporated by reference; 
see Sec. 430.3) applies to this test procedure, except that the term 
``wine chiller'' means ``cooler'' as defined in Sec. 430.2 and the term 
``wine chiller compartment'' means ``cooler compartment'' as defined in 
this appendix.
    Anti-sweat heater means a device incorporated into the design of a 
product to prevent the accumulation of moisture on the exterior or 
interior surfaces of the cabinet.
    Anti-sweat heater switch means a user-controllable switch or user 
interface which modifies the activation or control of anti-sweat 
heaters.
    AS/NZS 4474.1:2007 means Australian/New Zealand Standard 
4474.1:2007, Performance of household electrical appliances--
Refrigerating appliances, Part 1: Energy consumption and performance. 
Only sections of AS/NZS 4474.1:2007 (incorporated by reference; see 
Sec. 430.3) specifically referenced in this test procedure are part of 
this test procedure. In cases where there is a conflict, the language of 
the test procedure in this appendix takes precedence over AS/NZS 
4474.1:2007.
    Automatic defrost means a system in which the defrost cycle is 
automatically initiated

[[Page 329]]

and terminated, with resumption of normal refrigeration at the 
conclusion of the defrost operation. The system automatically prevents 
the permanent formation of frost on all refrigerated surfaces.
    Automatic icemaker means a device that can be supplied with water 
without user intervention, either from a pressurized water supply system 
or by transfer from a water reservoir located inside the cabinet, that 
automatically produces, harvests, and stores ice in a storage bin, with 
means to automatically interrupt the harvesting operation when the ice 
storage bin is filled to a pre-determined level.
    Cooler compartment means a refrigerated compartment designed 
exclusively for wine or other beverages within a consumer refrigeration 
product that is capable of maintaining compartment temperatures either 
(a) no lower than 39 [deg]F (3.9 [deg]C), or (b) in a range that extends 
no lower than 37 [deg]F (2.8 [deg]C) but at least as high as 60 [deg]F 
(15.6 [deg]C) as determined according to Sec. 429.14(d)(2) or Sec. 
429.61(d)(2) of this chapter.
    Complete temperature cycle means a time period defined based upon 
the cycling of compartment temperature that starts when the compartment 
temperature is at a maximum and ends when the compartment temperature 
returns to an equivalent maximum (within 0.5 [deg]F of the starting 
temperature), having in the interim fallen to a minimum and subsequently 
risen again to reach the second maximum. Alternatively, a complete 
temperature cycle can be defined to start when the compartment 
temperature is at a minimum and ends when the compartment temperature 
returns to an equivalent minimum (within 0.5 [deg]F of the starting 
temperature), having in the interim risen to a maximum and subsequently 
fallen again to reach the second minimum.
    Cycle means a 24-hour period for which the energy use of a product 
is calculated based on the consumer-activated compartment temperature 
controls being set to maintain the standardized temperatures (see 
section 3.2 of this appendix).
    Cycle type means the set of test conditions having the calculated 
effect of operating a product for a period of 24 hours, with the 
consumer-activated controls, other than those that control compartment 
temperatures, set to establish various operating characteristics.
    Defrost cycle type means a distinct sequence of control whose 
function is to remove frost and/or ice from a refrigerated surface. 
There may be variations in the defrost control sequence, such as the 
number of defrost heaters energized. Each such variation establishes a 
separate, distinct defrost cycle type. However, defrost achieved 
regularly during the compressor off-cycles by warming of the evaporator 
without active heat addition, although a form of automatic defrost, does 
not constitute a unique defrost cycle type for the purposes of 
identifying the test period in accordance with section 4 of this 
appendix.
    HRF-1-2008 means AHAM Standard HRF-1-2008, Association of Home 
Appliance Manufacturers, Energy and Internal Volume of Refrigerating 
Appliances (2008), including Errata to Energy and Internal Volume of 
Refrigerating Appliances, Correction Sheet issued November 17, 2009. 
Only sections of HRF-1-2008 (incorporated by reference; see Sec. 430.3) 
specifically referenced in this test procedure are part of this test 
procedure. In cases where there is a conflict, the language of the test 
procedure in this appendix takes precedence over HRF-1-2008.
    Ice storage bin means a container in which ice can be stored.
    Long-time automatic defrost means an automatic defrost system whose 
successive defrost cycles are separated by 14 hours or more of 
compressor operating time.
    Multiple-compressor product means a consumer refrigeration product 
with more than one compressor.
    Multiple refrigeration system product means a multiple-compressor 
product or a miscellaneous refrigeration product with more than one 
refrigeration system for which the operation of the systems is not 
coordinated. For non-compressor multiple refrigeration system products, 
``multiple-compressor product'' as used in this appendix shall be 
interpreted to mean ``multiple refrigeration system product.''
    Precooling means operating a refrigeration system before initiation 
of a defrost cycle to reduce one or more compartment temperatures 
significantly (more than 0.5 [deg]F) below its minimum during stable 
operation between defrosts.
    Recovery means operating a refrigeration system after the conclusion 
of a defrost cycle to reduce the temperature of one or more compartments 
to the temperature range that the compartment(s) exhibited during stable 
operation between defrosts.
    Separate auxiliary compartment means a separate freezer, fresh food, 
or cooler compartment that is not the primary freezer, primary fresh 
food, or primary cooler compartment. Separate auxiliary compartments may 
also be convertible (e.g., from fresh food to freezer). Separate 
auxiliary compartments may not be larger than the primary compartment of 
their type, but such size restrictions do not apply to separate 
auxiliary convertible compartments.
    Special compartment means any compartment other than a butter 
conditioner or a cooler compartment, without doors directly accessible 
from the exterior, and with separate temperature control (such as 
crispers convertible to meat keepers) that is not convertible from the 
fresh food temperature range to the freezer temperature range.

[[Page 330]]

    Stable operation means operation after steady-state conditions have 
been achieved but excluding any events associated with defrost cycles. 
During stable operation the average rate of change of compartment 
temperatures must not exceed 0.042 [deg]F (0.023 [deg]C) per hour for 
all compartment temperatures. Such a calculation performed for 
compartment temperatures at any two times, or for any two periods of 
time comprising complete cycles, during stable operation must meet this 
requirement.
    (a) If compartment temperatures do not cycle, the relevant 
calculation shall be the difference between the temperatures at two 
points in time divided by the difference, in hours, between those points 
in time.
    (b) If compartment temperatures cycle as a result of compressor 
cycling or other cycling operation of any system component (e.g., a 
damper, fan, heater, etc.), the relevant calculation shall be the 
difference between compartment temperature averages evaluated for the 
whole compressor cycles or complete temperature cycles divided by the 
difference, in hours, between either the starts, ends, or mid-times of 
the two cycles.
    Stabilization period means the total period of time during which 
steady-state conditions are being attained or evaluated.
    Standard cycle means the cycle type in which the anti-sweat heater 
control, when provided, is set in the highest energy-consuming position.
    Through-the-door ice/water dispenser means a device incorporated 
within the cabinet, but outside the boundary of the refrigerated space, 
that delivers to the user on demand ice and may also deliver water from 
within the refrigerated space without opening an exterior door. This 
definition includes dispensers that are capable of dispensing ice and 
water or ice only.
    Variable anti-sweat heater control means an anti-sweat heater 
control that varies the average power input of the anti-sweat heater(s) 
based on operating condition variable(s) and/or ambient condition 
variable(s).
    Variable defrost control means an automatic defrost system in which 
successive defrost cycles are determined by an operating condition 
variable (or variables) other than solely compressor operating time. 
This includes any electrical or mechanical device performing this 
function. A control scheme that changes the defrost interval from a 
fixed length to an extended length (without any intermediate steps) is 
not considered a variable defrost control. A variable defrost control 
feature predicts the accumulation of frost on the evaporator and reacts 
accordingly. Therefore, the times between defrost must vary with 
different usage patterns and include a continuum of periods between 
defrosts as inputs vary.

                           2. Test Conditions

    2.1 Ambient Temperature Measurement. Temperature measuring devices 
shall be shielded so that indicated temperatures are not affected by the 
operation of the condensing unit or adjacent units.
    2.1.1 Ambient Temperature. Measure and record the ambient 
temperature at points located 3 feet (91.5 cm) above the floor and 10 
inches (25.4 cm) from the center of the two sides of the unit under 
test. The ambient temperature shall be 90.0  1 
[deg]F (32.2  0.6 [deg]C) during the stabilization 
period and the test period.
    2.1.2 Ambient Temperature Gradient. The test room vertical ambient 
temperature gradient in any foot of vertical distance from 2 inches (5.1 
cm) above the floor or supporting platform to a height of 1 foot (30.5 
cm) above the top of the unit under test is not to exceed 0.5 [deg]F per 
foot (0.9 [deg]C per meter). The vertical ambient temperature gradient 
at locations 10 inches (25.4 cm) out from the centers of the two sides 
of the unit being tested is to be maintained during the test. To 
demonstrate that this requirement has been met, test data must include 
measurements taken using temperature sensors at locations 10 inches 
(25.4 cm) from the center of the two sides of the unit under test at 
heights of 2 inches (5.1 cm) and 36 inches (91.4 cm) above the floor or 
supporting platform and at a height of 1 foot (30.5 cm) above the unit 
under test.
    2.1.3 Platform. A platform must be used if the floor temperature is 
not within 3 [deg]F (1.7 [deg]C) of the measured ambient temperature. If 
a platform is used, it is to have a solid top with all sides open for 
air circulation underneath, and its top shall extend at least 1 foot 
(30.5 cm) beyond each side and the front of the unit under test and 
extend to the wall in the rear.
    2.2 Operational Conditions. The unit under test shall be installed 
and its operating conditions maintained in accordance with HRF-1-2008 
(incorporated by reference; see Sec. 430.3), sections 5.3.2 through 
5.5.5.5 (excluding section 5.5.5.4). Exceptions and clarifications to 
the cited sections of HRF-1-2008 are noted in sections 2.3 through 2.8 
and 5.1 of this appendix.
    2.3 Anti-Sweat Heaters. The anti-sweat heater switch is to be on 
during one test and off during a second test. In the case of a unit 
equipped with variable anti-sweat heater control, the standard cycle 
energy use shall be the result of the calculation described in section 
6.2.5 of this appendix.
    2.4 Conditions for Automatic Defrost Refrigerator-Freezers, Cooler-
Refrigerator-Freezers and Cooler-Freezers. For these products, the 
freezer compartments shall not be loaded with any frozen food packages 
during testing. Cylindrical metallic masses of dimensions 1.12  0.25 inches (2.9  0.6 cm) in

[[Page 331]]

diameter and height shall be attached in good thermal contact with each 
temperature sensor within the refrigerated compartments. All temperature 
measuring sensor masses shall be supported by low-thermal-conductivity 
supports in such a manner to ensure that there will be at least 1 inch 
(2.5 cm) of air space separating the thermal mass from contact with any 
interior surface or hardware inside the cabinet. In case of interference 
with hardware at the sensor locations specified in section 5.1 of this 
appendix, the sensors shall be placed at the nearest adjacent location 
such that there will be a 1-inch air space separating the sensor mass 
from the hardware.
    2.5 Conditions for All-Refrigerators and Cooler-All-Refrigerators. 
There shall be no load in the freezer compartment during the test.
    2.6 The cabinet and its refrigerating mechanism shall be assembled 
and set up in accordance with the printed consumer instructions supplied 
with the cabinet. Set-up of the test unit shall not deviate from these 
instructions, unless explicitly required or allowed by this test 
procedure. Specific required or allowed deviations from such set-up 
include the following:
    (a) Connection of water lines and installation of water filters are 
not required;
    (b) Clearance requirements from surfaces of the product shall be as 
described in section 2.8 of this appendix;
    (c) The electric power supply shall be as described in HRF-1-2008 
(incorporated by reference; see Sec. 430.3), section 5.5.1;
    (d) Temperature control settings for testing shall be as described 
in section 3 of this appendix. Settings for convertible compartments and 
other temperature-controllable or special compartments shall be as 
described in section 2.7 of this appendix;
    (e) The product does not need to be anchored or otherwise secured to 
prevent tipping during energy testing;
    (f) All the product's chutes and throats required for the delivery 
of ice shall be free of packing, covers, or other blockages that may be 
fitted for shipping or when the icemaker is not in use; and
    (g) Ice storage bins shall be emptied of ice.
    For cases in which set-up is not clearly defined by this test 
procedure, manufacturers must submit a petition for a waiver (see 
section 7 of this appendix).
    2.7 Compartments that are convertible (e.g., from fresh food to 
freezer or cooler) shall be operated in the highest energy use position. 
A compartment may be considered to be convertible to a cooler 
compartment if it is capable of maintaining compartment temperatures at 
least as high as 55 [deg]F (12.8 [deg]C) and also capable of operating 
at storage temperatures less than 37 [deg]F. For the special case of 
convertible separate auxiliary compartments, this means that the 
compartment shall be treated as a freezer compartment, a fresh food 
compartment, or a cooler compartment, depending on which of these 
represents the highest energy use.
    Special compartments shall be tested with controls set to provide 
the coldest temperature. However, for special compartments in which 
temperature control is achieved using the addition of heat (including 
resistive electric heating, refrigeration system waste heat, or heat 
from any other source, but excluding the transfer of air from another 
part of the interior of the product) for any part of the controllable 
temperature range of that compartment, the product energy use shall be 
determined by averaging two sets of tests. The first set of tests shall 
be conducted with such special compartments at their coldest settings, 
and the second set of tests shall be conducted with such special 
compartments at their warmest settings. The requirements for the warmest 
or coldest temperature settings of this section do not apply to features 
or functions associated with temperature controls (such as fast chill 
compartments) that are initiated manually and terminated automatically 
within 168 hours.
    Movable subdividing barriers that separate compartments shall be 
placed in the median position. If such a subdividing barrier has an even 
number of positions, the near-median position representing the smallest 
volume of the warmer compartment(s) shall be used.
    2.8 Rear Clearance.
    (a) General. The space between the lowest edge of the rear plane of 
the cabinet and a vertical surface (the test room wall or simulated 
wall) shall be the minimum distance in accordance with the 
manufacturer's instructions, unless other provisions of this section 
apply. The rear plane shall be considered to be the largest flat surface 
at the rear of the cabinet, excluding features that protrude beyond this 
surface, such as brackets or compressors.
    (b) Maximum clearance. The clearance shall not be greater than 2 
inches (51 mm) from the lowest edge of the rear plane to the vertical 
surface, unless the provisions of paragraph (c) of this section apply.
    (c) If permanent rear spacers or other components that protrude 
beyond the rear plane extend further than the 2-inch (51 mm) distance, 
or if the highest edge of the rear plane is in contact with the vertical 
surface when the unit is positioned with the lowest edge of the rear 
plane at or further than the 2-inch (51 mm) distance from the vertical 
surface, the appliance shall be located with the spacers or other 
components protruding beyond the rear plane, or the highest edge of the 
rear plane, in contact with the vertical surface.
    (d) Rear-mounted condensers. If the product has a flat rear-wall-
mounted condenser (i.e., a rear-wall-mounted condenser with all 
refrigerant tube centerlines within 0.25

[[Page 332]]

inches (6.4 mm) of the condenser plane), and the area of the condenser 
plane represents at least 25% of the total area of the rear wall of the 
cabinet, then the spacing to the vertical surface may be measured from 
the lowest edge of the condenser plane.
    2.9 Steady-State Condition. Steady-state conditions exist if the 
temperature measurements in all measured compartments taken at 4-minute 
intervals or less during a stabilization period are not changing at a 
rate greater than 0.042 [deg]F (0.023 [deg]C) per hour as determined by 
the applicable condition of paragraph (a) or (b) of this section.
    (a) The average of the measurements during a 2-hour period if no 
cycling occurs or during a number of complete repetitive compressor 
cycles occurring through a period of no less than 2 hours is compared to 
the average over an equivalent time period with 3 hours elapsing between 
the two measurement periods.
    (b) If paragraph (a) of this section cannot be used, the average of 
the measurements during a number of complete repetitive compressor 
cycles occurring through a period of no less than 2 hours and including 
the last complete cycle before a defrost period (or if no cycling 
occurs, the average of the measurements during the last 2 hours before a 
defrost period) are compared to the same averaging period before the 
following defrost period.
    2.10 Products with Demand-Response Capability. Products that have a 
communication module for demand-response functions that is located 
within the cabinet shall be tested with the communication module in the 
configuration set at the factory just before shipping.

                        3. Test Control Settings

    3.1 Model with No User-Operable Temperature Control. A test shall be 
performed to measure the compartment temperatures and energy use. A 
second test shall be performed with the temperature control electrically 
short circuited to cause the compressor to run continuously (or to cause 
the non-compressor refrigeration system to run continuously at maximum 
capacity).
    3.2 Models with User-Operable Temperature Control. Testing shall be 
performed in accordance with the procedure in this section using the 
following standardized temperatures:
    39 [deg]F (3.9 [deg]C) fresh food compartment temperature;
    0 [deg]F (-17.8 [deg]C) freezer compartment temperature, except for 
freezer compartments in refrigerators and cooler-refrigerators, in which 
case testing would use a 15 [deg]F (-9.4 [deg]C) freezer compartment 
temperature; and
    55 [deg]F (12.8 [deg]C) cooler compartment temperature.
    For the purposes of comparing compartment temperatures with 
standardized temperatures, as described in sections 3.2.1 and 3.2.2 of 
this appendix, the freezer compartment temperature shall be as specified 
in section 5.1.4 of this appendix, the fresh food compartment 
temperature shall be as specified in section 5.1.3 of this appendix, and 
the cooler compartment temperature shall be as specified in section 
5.1.5 of this appendix.
    3.2.1 Temperature Control Settings and Tests to Use for Energy Use 
Calculations.
    3.2.1.1 Setting Temperature Controls. For mechanical control 
systems, (a) knob detents shall be mechanically defeated if necessary to 
attain a median setting, and (b) the warmest and coldest settings shall 
correspond to the positions in which the indicator is aligned with 
control symbols indicating the warmest and coldest settings. For 
electronic control systems, the test shall be performed with all 
compartment temperature controls set at the average of the coldest and 
warmest settings; if there is no setting equal to this average, the 
setting closest to the average shall be used. If there are two such 
settings equally close to the average, the higher of these temperature 
control settings shall be used.
    3.2.1.2 Test Sequence. A first test shall be performed with all 
compartment temperature controls set at their median position midway 
between their warmest and coldest settings. A second test shall be 
performed with all controls set at their warmest setting or all controls 
set at their coldest setting (not electrically or mechanically 
bypassed). For units with a single standardized temperature (e.g., all-
refrigerator or cooler), this setting shall be the appropriate setting 
that attempts to achieve compartment temperatures measured during the 
two tests that bound (i.e., one is above and one is below) the 
standardized temperature. For other units, the second test shall be 
conducted with all controls at their coldest setting, unless all 
compartment temperatures measured during the first test are lower than 
the standardized temperatures, in which case the second test shall be 
conducted with all controls at their warmest setting. If any compartment 
is warmer than its standardized temperature for a test with all controls 
at their coldest position, the product receives no energy use rating and 
the manufacturer must submit a petition for a waiver (see section 7 of 
this appendix).
    3.2.1.3 Temperature Setting Table. See Table 1 of this section for a 
general description of which settings to use and which test results to 
use in the energy consumption calculation for products with one, two, or 
three standardized temperatures.

----------------------------------------------------------------------------------------------------------------

    3.2.2 Alternatively, a first test may be performed with all 
temperature controls set at their warmest setting. If all compartment 
temperatures are below the appropriate standardized temperatures, then 
the result of this test alone will be used to determine energy 
consumption. If this condition is not met, then the unit shall be tested 
in accordance with section 3.2.1 of this appendix.
    3.2.3 Temperature Settings for Separate Auxiliary Convertible 
Compartments. For separate auxiliary convertible compartments tested as 
freezer compartments, the median setting shall be within 2 [deg]F (1.1 
[deg]C) of the standardized freezer compartment temperature, and the 
warmest setting shall be at least 5 [deg]F (2.8 [deg]C) warmer than the 
standardized temperature. For separate auxiliary convertible 
compartments tested as fresh food compartments, the median setting shall 
be within 2 [deg]F (1.1 [deg]C) of 39 [deg]F (3.9 [deg]C), the coldest 
setting shall be below 34 [deg]F (1.1 [deg]C), and the warmest setting 
shall be above 43 [deg]F (6.1 [deg]C). For separate auxiliary 
convertible compartments tested as cooler compartments, the median 
setting shall be within 2 [deg]F (1.1 [deg]C) of 55 [deg]F (12.8 
[deg]C), and the coldest setting shall be below 50 [deg]F (10.0 [deg]C). 
For compartments where control settings are not expressed as particular 
temperatures, the measured temperature of the convertible compartment 
rather than the settings shall meet the specified criteria.
    3.3 Optional Test for Models with Two Compartments and User-Operable 
Controls. As an alternative to section 3.2 of this appendix, perform 
three tests such that the set of tests meets the ``minimum requirements 
for interpolation'' of AS/NZS 4474.1:2007 (incorporated by reference; 
see Sec. 430.3) appendix M, section M3, paragraphs (a) through (c) and 
as illustrated in Figure M1. The target temperatures txA and 
txB defined in section M4(a)(i) of AS/NZ 4474.1:2007 shall be 
the standardized temperatures defined in section 3.2 of this appendix.

                             4. Test Period

    Tests shall be performed by establishing the conditions set forth in 
section 2, and using the control settings set forth in section 3.
    4.1 Non-automatic Defrost. If the model being tested has no 
automatic defrost system, the test period shall start after steady-state 
conditions (see section 2.9 of this appendix) have been achieved and be 
no less than three hours in duration. During the test period, the 
compressor motor shall complete two or more whole compressor cycles. (A 
compressor cycle is a complete ``on'' and a complete ``off'' period of 
the motor.) If no ``off'' cycling occurs, the test period shall be three 
hours. If fewer than two compressor cycles occur during a 24-hour 
period, then a single complete compressor cycle may be used.
    4.2 Automatic Defrost. If the model being tested has an automatic 
defrost system, the test period shall start after steady-state 
conditions have been achieved and be from one point during a defrost 
period to the same point during the next defrost period. If the model 
being tested has a long-time automatic defrost system, the alternative 
provisions of section 4.2.1 may be used. If the model being tested has a 
variable defrost control, the provisions of section 4.2.2 shall apply. 
If the model is a multiple-compressor product with automatic defrost, 
the provisions of section 4.2.3 shall apply. If the model being tested 
has long-time automatic or variable defrost control involving multiple 
defrost cycle types, such as for a product with a single compressor and 
two or more evaporators in which the evaporators are defrosted at 
different frequencies, the provisions of section 4.2.4 shall apply. If 
the model being tested has multiple defrost cycle types for which 
compressor run time between defrosts is a fixed time of less than 14 
hours for all such cycle types, and for which the compressor run times 
between defrosts for different defrost cycle types are equal to or 
multiples of each other, the test period shall be from one point of the 
defrost cycle type with the longest compressor run time between defrosts 
to the same point during the next occurrence of this defrost cycle type. 
For such products not using the procedures of section 4.2.4, energy 
consumption shall be

[[Page 334]]

calculated as described in section 5.2.1.1 of this appendix.
    4.2.1 Long-time Automatic Defrost. If the model being tested has a 
long-time automatic defrost system, the two-part test described in this 
section may be used. The first part is a stable period of compressor 
operation that includes no portions of the defrost cycle, such as 
precooling or recovery, that is otherwise the same as the test for a 
unit having no defrost provisions (section 4.1). The second part is 
designed to capture the energy consumed during all of the events 
occurring with the defrost control sequence that are outside of stable 
operation.
    4.2.1.1 Cycling Compressor System. For a system with a cycling 
compressor, the second part of the test starts at the termination of the 
last regular compressor ``on'' cycle. The average compartment 
temperatures measured from the termination of the previous compressor 
``on'' cycle to the termination of the last regular compressor ``on'' 
cycle must both be within 0.5 [deg]F (0.3 [deg]C) of their average 
temperatures measured for the first part of the test. If any compressor 
cycles occur prior to the defrost heater being energized that cause the 
average temperature in any compartment to deviate from its average 
temperature for the first part of the test by more than 0.5 [deg]F (0.3 
[deg]C), these compressor cycles are not considered regular compressor 
cycles and must be included in the second part of the test. As an 
example, a ``precooling'' cycle, which is an extended compressor cycle 
that lowers the temperature(s) of one or more compartments prior to 
energizing the defrost heater, must be included in the second part of 
the test. The test period for the second part of the test ends at the 
termination of the first regular compressor ``on'' cycle after 
compartment temperatures have fully recovered to their stable 
conditions. The average temperatures of the compartments measured from 
this termination of the first regular compressor ``on'' cycle until the 
termination of the next regular compressor ``on'' cycle must both be 
within 0.5 [deg]F (0.3 [deg]C) of their average temperatures measured 
for the first part of the test. See Figure 1 of this section. Note that 
Figure 1 illustrates the concepts of precooling and recovery but does 
not represent all possible defrost cycles.

    4.2.1.2 Non-cycling Compressor System. For a system with a non-
cycling compressor, the second part of the test starts at a time before 
defrost during stable operation when compartment temperatures are within 
0.5 [deg]F (0.3 [deg]C) of their average temperatures measured for the 
first part of the test. The second part stops at a time after defrost 
during stable operation when the compartment temperatures are within 0.5 
[deg]F (0.3 [deg]C) of their average temperatures measured for the first 
part of the test. See Figure 2 of this section.

[[Page 336]]

[GRAPHIC] [TIFF OMITTED] TR18JY16.005

    4.2.2 Variable Defrost Control. If the model being tested has a 
variable defrost control system, the test shall consist of the same two 
parts as the test for long-time automatic defrost (section 4.2.1).
    4.2.3 Multiple-compressor Products with Automatic Defrost.
    4.2.3.1 Measurement Frequency. Measurements of power input, 
cumulative electric energy consumption (watt-hours or kilowatt-hours), 
and compartment temperature shall be taken at regular intervals not 
exceeding one minute.
    4.2.3.2 Steady-state Condition. Steady state shall be considered to 
have been attained after 24 hours of operation after the last adjustment 
of the temperature controls.
    4.2.3.3 Primary Compressor. If at least one compressor cycles, test 
periods shall be based on compressor cycles associated with the primary 
compressor system (these are referred to as ``primary compressor 
cycles''). If the freezer compressor cycles, it shall be the primary 
compressor system.
    4.2.3.4 Test Periods. The two-part test described in this section 
shall be used. The first part is a stable continuous period of 
compressor operation that includes no defrost cycles or events 
associated with a defrost cycle, such as precooling or recovery, for any 
compressor system. The second part is a continuous test period designed 
to capture the energy consumed during all of the events occurring with 
the defrost control sequence that are outside of stable operation. The 
second part of the test shall be conducted separately for each automatic 
defrost system present.
    4.2.3.4.1 First Part of Test. If at least one compressor cycles, the 
test period for the first part of the test shall include a whole number 
of complete primary compressor cycles comprising at least 24 hours of 
stable operation, unless a defrost occurs prior to completion of 24 
hours of stable operation, in

[[Page 337]]

which case the first part of the test shall include a whole number of 
complete primary compressor cycles comprising at least 18 hours of 
stable operation. If no compressor cycles, the first part of the test 
shall comprise at least 24 hours of stable operation, unless a defrost 
occurs prior to completion of 24 hours of stable operation, in which 
case the first part of the test shall comprise at least 18 hours of 
stable operation.
    4.2.3.4.2 Second Part of Test. (a) If at least one compressor 
cycles, the test period for the second part of the test starts during 
stable operation before all portions of the defrost cycle, at the 
beginning of a complete primary compressor cycle. The test period for 
the second part of the test ends during stable operation after all 
portions of the defrost cycle, including recovery, at the termination of 
a complete primary compressor cycle. The start and stop for the test 
period shall both occur either when the primary compressor starts or 
when the primary compressor stops. For each compressor system, the 
compartment temperature averages for the first and last complete 
compressor cycles that lie completely within the second part of the test 
must be within 0.5 [deg]F (0.3 [deg]C) of the average compartment 
temperature measured for the first part of the test. If any one of the 
compressor systems is non-cycling, its compartment temperature averages 
during the first and last complete primary compressor cycles of the 
second part of the test must be within 0.5 [deg]F (0.3 [deg]C) of the 
average compartment temperature measured for the first part of the test.
    (b) If no compressor cycles, the test period for the second part of 
the test starts during stable operation before all portions of the 
defrost cycle, when the compartment temperatures of all compressor 
systems are within 0.5 [deg]F (0.3 [deg]C) of their average temperatures 
measured for the first part of the test. The test period for the second 
part ends during stable operation after all portions of the defrost 
cycle, including recovery, when the compartment temperatures of all 
compressor systems are within 0.5 [deg]F (0.3 [deg]C) of their average 
temperatures measured for the first part of the test.
    4.2.4 Systems with Multiple Defrost Frequencies. This section 
applies to models with long-time automatic or variable defrost control 
with multiple defrost cycle types, such as models with single 
compressors and multiple evaporators in which the evaporators have 
different defrost frequencies. The two-part method in 4.2.1 shall be 
used. The second part of the method will be conducted separately for 
each distinct defrost cycle type.

                          5. Test Measurements

    5.1 Temperature Measurements. (a) Temperature measurements shall be 
made at the locations prescribed in HRF-1-2008 (incorporated by 
reference; see Sec. 430.3) Figure 5.1 for cooler and fresh food 
compartments and Figure 5.2 for freezer compartments and shall be 
accurate to within 0.5 [deg]F (0.3 [deg]C). No 
freezer temperature measurements need be taken in an all-refrigerator or 
cooler-all-refrigerator.
    (b) If the interior arrangements of the unit under test do not 
conform with those shown in Figures 5.1 or 5.2 of HRF-1-2008, as 
appropriate, the unit must be tested by relocating the temperature 
sensors from the locations specified in the figures to avoid 
interference with hardware or components within the unit, in which case 
the specific locations used for the temperature sensors shall be noted 
in the test data records maintained by the manufacturer in accordance 
with 10 CFR 429.71, and the certification report shall indicate that 
non-standard sensor locations were used. If any temperature sensor is 
relocated by any amount from the location prescribed in Figure 5.1 or 
5.2 of HRF-1- 2008 in order to maintain a minimum 1-inch air space from 
adjustable shelves or other components that could be relocated by the 
consumer, except in cases in which the Figures prescribe a temperature 
sensor location within 1 inch of a shelf or similar feature (e.g., 
sensor T3 in Figure 5.1), this constitutes a relocation of 
temperature sensors that must be recorded in the test data and reported 
in the certification report as described in this paragraph (b).
    5.1.1 Measured Temperature. The measured temperature of a 
compartment is the average of all sensor temperature readings taken in 
that compartment at a particular point in time. Measurements shall be

multiple refrigeration system products shall be taken at regular 
intervals not to exceed one minute.
    5.1.2 Compartment Temperature. The compartment temperature for each 
test period shall be an average of the measured temperatures taken in a 
compartment during the test period as defined in section 4 of this 
appendix. For long-time automatic defrost models, compartment 
temperatures shall be those measured in the first part of the test 
period specified in section 4.2.1 of this appendix. For models with 
variable defrost controls, compartment temperatures shall be those 
measured in the first part of the test period specified in section 4.2.2 
of this appendix. For models with automatic defrost that is neither 
long-time nor variable defrost, the compartment temperature shall be an 
average of the measured temperatures taken in a compartment during a 
stable period of compressor operation that:
    (a) Includes no defrost cycles or events associated with a defrost 
cycle, such as precooling or recovery;
    (b) Is no less than three hours in duration; and

[[Page 338]]

    (c) Includes two or more whole compressor cycles. If the compressor 
does not cycle, the stable period used for the temperature average shall 
be three hours in duration.

          ``i'' determined in accordance with section 5.1.2 of this 
          appendix; and

appendix adjusted to a 24-hour period. The adjustment shall be 
determined as follows.

consumption in kilowatt-hours per day shall be calculated equivalent to:

ET = (EP x 1440 x K)/T

Where:

          hours per day.

    5.2.1.3 Variable Defrost Control. The energy consumption in 
kilowatt-hours per day shall be calculated equivalent to:

ET = (1440 x K x EP1/T1) + (EP2 - (EP1 x T2/T1)) x K x (12/CT),

          T1, T2, and 12 are defined in section 5.2.1.2 of this 
          appendix;
CT = (CTL x CTM)/(F x (CTM - 
          CTL) + CTL);
CTL = the shortest compressor run time between defrosts used 
          in the variable defrost control algorithm (greater than or 
          equal to 6 but less than or equal to 12 hours), or the 
          shortest compressor run time between defrosts observed for the 
          test (if it is shorter than the shortest run time used in the 
          control algorithm and is greater than 6 hours), or 6 hours (if

CTM in the algorithm, the default values of 6 and 96 shall be 
used, respectively.
    5.2.1.4 Multiple Compressor Products with Automatic Defrost. For

(CTLi x CTMi)/(F x (CTMi- 
          CTLi) + CTLi);

Where:

CTLi = for compressor system i, the shortest compressor run 
          time between defrosts used in the variable defrost control 
          algorithm (greater than or equal to 6 but less than or equal 
          to 12 hours), or the shortest compressor run time between 
          defrosts observed for the test (if it is shorter than the 
          shortest run time used in the control algorithm and is greater 
          than 6 hours), or 6 hours (if the shortest observed run time 
          is less than 6 hours), in hours rounded to the nearest tenth 
          of an hour;

[GRAPHIC] [TIFF OMITTED] TR18JY16.010

Where:

1440 and K are defined in section 5.2.1.1 of this appendix and EP1, T1, 
          and 12 are defined in section 5.2.1.2 of this appendix;

CTLi = least or shortest compressor run time between 
          instances of defrost cycle type i in hours rounded to the

    For cases in which there are more than one fixed CT value (for long-
time defrost models) or more than one CTM and/or 
CTL value (for variable defrost models) for a given defrost 
cycle type, an average fixed CT value or average CTM and 
CTL values shall be selected for this cycle type so that 12 
divided by this value or values is the frequency of occurrence of the 
defrost cycle type in a 24 hour period, assuming 50% compressor run 
time.

F = default defrost energy consumption factor, equal to 0.20.

    For variable defrost models with no values for CTLi and 
CTMi in the algorithm, the default values of 6 and 96 shall 
be used, respectively.
    D is the total number of distinct defrost cycle types.
    5.3 Volume Measurements. (a) The unit's total refrigerated volume, 
VT, shall be measured in accordance with HRF-1-2008, (incorporated by 
reference; see Sec. 430.3), section 3.30 and sections 4.2 through 4.3. 
The measured volume shall include all spaces within the insulated volume 
of each compartment except for the volumes that must be deducted in 
accordance with section 4.2.2 of HRF-1-2008, as provided in paragraph 
(b) of this section, and be calculated equivalent to:

VT = VF + VFF + VC

Where:

VT = total refrigerated volume in cubic feet,
VF = freezer compartment volume in cubic feet,
VFF = fresh food compartment volume in cubic feet, and
VC = cooler compartment volume in cubic feet.

    (b) The following component volumes shall not be included in the 
compartment volume measurements: Icemaker compartment insulation (e.g., 
insulation isolating the icemaker compartment from the fresh food 
compartment of a product with a bottom-mounted freezer with through-the-
door ice service), fountain recess, dispenser insulation, and ice chute 
(if there is a plug, cover, or cap over the chute per Figure 4-2 of HRF-
1-2008). The following component volumes shall be included in the 
compartment volume measurements: Icemaker auger motor (if housed inside 
the insulated space of the cabinet), icemaker kit, ice storage bin, and 
ice chute (up to the dispenser flap, if there is no plug, cover, or cap 
over the ice chute per Figure 4-3 of HRF-1-2008).
    (c) Total refrigerated volume is determined by physical measurement 
of the test unit. Measurements and calculations used to determine the 
total refrigerated volume shall be retained as part of the test records 
underlying the certification of the basic model in accordance with 10 
CFR 429.71.
    (d) Compartment classification shall be based on subdivision of the 
refrigerated volume into zones separated from each other by subdividing 
barriers: No evaluated compartment shall be a zone of a larger 
compartment unless the zone is separated from the

[[Page 341]]

remainder of the larger compartment by subdividing barriers; if there 
are no such subdividing barriers within the larger compartment, the 
larger compartment must be evaluated as a single compartment rather than 
as multiple compartments. If the cabinet contains a movable subdividing 
barrier, it must be placed as described in section 2.7 of this appendix.
    (e) Freezer, fresh food, and cooler compartment volumes shall be 
calculated and recorded to the nearest 0.01 cubic foot. Total 
refrigerated volume shall be calculated and recorded to the nearest 0.1 
cubic foot.

        6. Calculation of Derived Results From Test Measurements

    6.1 Adjusted Total Volume. The adjusted total volume of each tested 
unit must be determined based upon the volume measured in section 5.3 of 
this appendix using the following calculations. Where volume 
measurements for the freezer, fresh food, and cooler compartment are 
recorded in liters, the measured volume must be converted to cubic feet 
and rounded to the nearest 0.01 cubic foot prior to calculating the 
adjusted volume. Adjusted total volume shall be calculated and recorded 
to the nearest 0.1 cubic foot.
    6.1.1 Refrigerators, Coolers, and Cooler-Refrigerators. The adjusted 
total volume, AV, for refrigerators or cooler-refrigerators under test, 
shall be defined as:

AV = (VF x CR) + VFF + VC

Where:

AV = adjusted total volume in cubic feet;
VF, VFF, and VC are defined in section 5.3 of this appendix;
CR = dimensionless adjustment factor for freezer compartments of 1.00 
          for all-refrigerators and cooler-all-refrigerators, or 1.47 
          for other types of refrigerators and cooler-refrigerators; and

    6.1.2 Refrigerator-Freezers, Cooler-Refrigerator-Freezers, and 
Cooler-Freezers. The adjusted total volume, AV, for refrigerator-
freezers, cooler-refrigerator-freezers, and cooler-freezers under test 
shall be calculated as follows:

AV = (VF x CRF) + VFF + VC

Where:

VF, VFF, and VC are defined in section 5.3 and AV is defined in section 
          6.1.1 of this appendix;
CRF = dimensionless adjustment factor for freezer compartments of 1.76; 
          and

    6.2 Average Per-Cycle Energy Consumption. The average per-cycle 
energy consumption for a cycle type, E, is expressed in kilowatt-hours 
per cycle to the nearest one hundredth (0.01) kilowatt-hour and shall be 
calculated according to the sections below.
    6.2.1 All-Refrigerator Models. The average per-cycle energy 
consumption shall depend upon the temperature attainable in the fresh 
food compartment as shown in section 6.2.1.1 of this appendix.
    6.2.1.1 If the fresh food compartment temperature is always below 
39.0 [deg]F (3.9 [deg]C), the average per-cycle energy consumption shall 
be equivalent to:

E = ET1

Where:

ET is defined in section 5.2.1 of this appendix; and
The number 1 indicates the test during which the highest fresh food 
          compartment temperature is measured.

          5.1.3 of this appendix in degrees F;
The numbers 1 and 2 indicate measurements taken during the two tests to 
          be used to calculate energy consumption, as specified in 
          section 3 of this appendix; and
39.0 = standardized fresh food compartment temperature in degrees F.

    6.2.2 Coolers. The average per-cycle energy consumption shall depend 
upon the temperature attainable in the cooler compartment as shown in 
section 6.2.2.1 of this appendix.
    6.2.2.1 If the cooler compartment temperature is always below 55.0 
[deg]F (12.8 [deg]C), the average per-cycle energy consumption shall be

The number 1 indicates the test during which the highest cooler 
          compartment temperature is measured.

[deg]F (3.9 [deg]C) and the freezer compartment temperature is always 
below 15 [deg]F (-9.4 [deg]C) in both tests of a refrigerator or always 
below 0 [deg]F (-17.8 [deg]C) in both tests of a refrigerator-freezer, 
the average per-cycle energy consumption shall be:

E = ET1 + IET

Where:

apply, the average per-cycle energy consumption shall be defined by the 
higher of the two values calculated by the following two formulas:

          each being a standardized freezer compartment temperature in 
          degrees F.

    6.2.4 Combination Cooler Refrigeration Products. The average per-
cycle energy consumption shall be defined in one of the following ways 
as applicable.
    6.2.4.1 If the compartment temperatures are always below their 
compartments' standardized temperatures as defined in section 3.2 of 
this appendix (the fresh food compartment temperature is at or below 39 
[deg]F (3.9 [deg]C); the cooler compartment temperature is at or below 
55 [deg]F (12.8 [deg]C); and the freezer compartment temperature is at 
or below 15 [deg]F (-9.4 [deg]C) for a cooler-refrigerator, or the

for a cooler-refrigerator-freezer or cooler-freezer), the average per-
cycle energy consumption shall be:

E = ET1 + IET

Where:

IET is defined in section 6.2.3.1 of this appendix;
The number 1 indicates the test during which the highest freezer

          freezer compartment, the number 1 indicates the test during 
          which the highest fresh food compartment temperature is 
          measured.

    6.2.4.2 If the conditions of section 6.2.4.1 of this appendix do not 
apply, the average per-cycle energy consumption shall be defined by the 
highest of the two or three values calculated by the following three 
formulas:

E = (ET1 + ((ET2 - ET1) x (39.0 - TR1)/(TR2 - TR1)) + IET if the product 
          has a fresh food compartment;
E = (ET1 + ((ET2 - ET1) x (k - TF1)/(TF2 - TF1)) + IET if the product 
          has a freezer compartment; and

    6.2.5 Variable Anti-Sweat Heater Models. The standard cycle energy 
consumption of a model with a variable anti-sweat heater control 
(Estd), expressed in kilowatt-hours per day, shall be 
calculated equivalent to:
    Estd = E + (Correction Factor) where E is determined by 
sections 6.2.1, 6.2.2, 6.2.3, or 6.2.4 of this appendix, whichever is 
appropriate, with the anti-sweat heater switch in the ``off'' position 
or, for a product without an anti-sweat heater switch, the anti-sweat 
heater in its lowest energy use state.

Correction Factor = (Anti-sweat Heater Power x System-loss Factor) x (24 
          hrs/1 day) x (1 kW/1000 W)


[[Page 343]]


Where:

Anti-sweat Heater Power = 0.034 * (Heater Watts at 5%RH)
+ 0.211 * (Heater Watts at 15%RH)
+ 0.204 * (Heater Watts at 25%RH)

+ 0.047 * (Heater Watts at 75%RH)
+ 0.008 * (Heater Watts at 85%RH)
+ 0.015 * (Heater Watts at 95%RH)
Heater Watts at a specific relative humidity = the nominal watts used by 
          all heaters at that specific relative humidity, 72 [deg]F 
          (22.2 [deg]C) ambient, and DOE reference temperatures of fresh 
          food (FF) average temperature of 39 [deg]F (3.9 [deg]C) and 
          freezer (FZ) average temperature of 0 [deg]F (-17.8 [deg]C).

                        7. Test Procedure Waivers

    To the extent that the procedures contained in this appendix do not 
provide a means for determining the energy consumption of a basic model, 
a manufacturer must obtain a waiver under Sec. 430.27 to establish an 
acceptable test procedure for each such basic model. Such instances 
could, for example, include situations where the test set-up for a 
particular basic model is not clearly defined by the provisions of 
section 2 of this appendix. For details regarding the criteria and 
procedures for obtaining a waiver, please refer to Sec. 430.27.

   Sec. Appendix B to Subpart B of Part 430--Uniform Test Method for 
              Measuring the Energy Consumption of Freezers

    Note: For freezers, the rounding requirements specified in sections 
5.3.e and 6.1 of this appendix are not required for use until the 
compliance date of any amended energy conservation standards for these 
products.

                             1. Definitions

    Section 3, Definitions, of HRF-1-2008 (incorporated by reference; 
see Sec. 430.3) applies to this test procedure.
    Adjusted total volume means the product of the freezer volume as 
defined in HRF-1-2008 (incorporated by reference; see Sec. 430.3) in 
cubic feet multiplied by an adjustment factor.
    Anti-sweat heater means a device incorporated into the design of a 
freezer to prevent the accumulation of moisture on exterior or interior 
surfaces of the cabinet.
    Anti-sweat heater switch means a user-controllable switch or user 
interface which modifies the activation or control of anti-sweat 
heaters.
    Automatic defrost means a system in which the defrost cycle is 
automatically initiated and terminated, with resumption of normal 
refrigeration at the conclusion of defrost operation. The system 
automatically prevents the permanent formation of frost on all 
refrigerated surfaces. Nominal refrigerated food temperatures are 
maintained during the operation of the automatic defrost system.
    Automatic icemaker means a device that can be supplied with water 
without user intervention, either from a pressurized water supply system 
or by transfer from a water reservoir that automatically produces, 
harvests, and stores ice in a storage bin, with means to automatically 
interrupt the harvesting operation when the ice storage bin is filled to 
a pre-determined level.
    Complete temperature cycle means a time period defined based upon 
the cycling of compartment temperature that starts when the compartment 
temperature is at a maximum and ends when the compartment temperature 
returns to an equivalent maximum (within 0.5 [deg]F of the starting 
temperature), having in the interim fallen to a minimum and subsequently 
risen again to reach the second maximum. Alternatively, a complete 
temperature cycle can be defined to start when the compartment 
temperature is at a minimum and end when the compartment temperature 
returns to an equivalent minimum (within 0.5 [deg]F of the starting 
temperature), having in the interim risen to a maximum and subsequently 
fallen again to reach the second minimum.
    Cycle means the period of 24 hours for which the energy use of a 
freezer is calculated as though the consumer-activated compartment 
temperature controls were set to maintain the standardized temperature 
(see section 3.2 of this appendix).
    Cycle type means the set of test conditions having the calculated 
effect of operating a freezer for a period of 24 hours with the 
consumer-activated controls other than the compartment temperature 
control set to establish various operating characteristics.
    HRF-1-2008 means AHAM Standard HRF-1-2008, Association of Home 
Appliance Manufacturers, Energy and Internal Volume of Refrigerating 
Appliances (2008), including Errata to Energy and Internal Volume of 
Refrigerating Appliances, Correction Sheet issued November 17, 2009. 
Only sections of HRF-1-2008 (incorporated by reference; see Sec. 430.3) 
specifically referenced in this test procedure are part of this test 
procedure. In cases where there is a conflict, the language of the test 
procedure in this appendix takes precedence over HRF-1-2008.
    Ice storage bin means a container in which ice can be stored.

[[Page 344]]

    Long-time automatic defrost means an automatic defrost system where 
successive defrost cycles are separated by 14 hours or more of 
compressor operating time.
    Precooling means operating a refrigeration system before initiation 
of a defrost cycle to reduce one or more compartment temperatures 
significantly (more than 0.5 [deg]F) below its minimum during stable 
operation between defrosts.
    Quick freeze means an optional feature on freezers that is initiated 
manually. It bypasses the thermostat control and operates continually 
until the feature is terminated either manually or automatically.
    Recovery means operating a refrigeration system after the conclusion 
of a defrost cycle to reduce the temperature of one or more compartments 
to the temperature range that the compartment(s) exhibited during stable 
operation between defrosts.
    Separate auxiliary compartment means a freezer compartment other 
than the primary freezer compartment of a freezer having more than one 
compartment. Access to a separate auxiliary compartment is through a 
separate exterior door or doors rather than through the door or doors of 
another compartment. Separate auxiliary freezer compartments may not be 
larger than the primary freezer compartment.
    Special compartment means any compartment without doors directly 
accessible from the exterior, and with separate temperature control that 
is not convertible from fresh food temperature range to freezer 
temperature range.
    Stabilization period means the total period of time during which 
steady-state conditions are being attained or evaluated.
    Stable operation means operation after steady-state conditions have 
been achieved but excluding any events associated with defrost cycles. 
During stable operation the average rate of change of compartment 
temperature must not exceed 0.042 [deg]F (0.023 [deg]C) per hour. Such a 
calculation performed for compartment temperatures at any two times, or 
for any two periods of time comprising complete cycles, during stable 
operation must meet this requirement.
    (a) If compartment temperatures do not cycle, the relevant 
calculation shall be the difference between the temperatures at two 
points in time divided by the difference, in hours, between those points 
in time.
    (b) If compartment temperatures cycle as a result of compressor 
cycling or other cycling operation of any system component (e.g., a 
damper, fan, or heater), the relevant calculation shall be the 
difference between compartment temperature averages evaluated for whole 
compressor cycles or complete temperature cycles divided by the 
difference, in hours, between either the starts, ends, or mid-times of 
the two cycles.
    Standard cycle means the cycle type in which the anti-sweat heater 
switch, when provided, is set in the highest energy-consuming position.
    Through-the-door ice/water dispenser means a device incorporated 
within the cabinet, but outside the boundary of the refrigerated space, 
that delivers to the user on demand ice and may also deliver water from 
within the refrigerated space without opening an exterior door. This 
definition includes dispensers that are capable of dispensing ice and 
water or ice only.
    Variable defrost control means an automatic defrost system in which 
successive defrost cycles are determined by an operating condition 
variable (or variables) other than solely compressor operating time. 
This includes any electrical or mechanical device performing this 
function. A control scheme that changes the defrost interval from a 
fixed length to an extended length (without any intermediate steps) is 
not considered a variable defrost control. A variable defrost control 
feature should predict the accumulation of frost on the evaporator and 
react accordingly. Therefore, the times between defrost must vary with 
different usage patterns and include a continuum of lengths of time 
between defrosts as inputs vary.

                           2. Test Conditions

    2.1 Ambient Temperature Measurement. Temperature measuring devices 
shall be shielded so that indicated temperatures are not affected by the 
operation of the condensing unit or adjacent units.
    2.1.1 Ambient Temperature. The ambient temperature shall be recorded 
at points located 3 feet (91.5 cm) above the floor and 10 inches (25.4 
cm) from the center of the two sides of the unit under test. The ambient 
temperature shall be 90.0 1.0 [deg]F (32.2 0.6 [deg]C) during the stabilization period and the test 
period.
    2.1.2 Ambient Temperature Gradient. The test room vertical ambient 
temperature gradient in any foot of vertical distance from 2 inches (5.1 
cm) above the floor or supporting platform to a height of 1 foot (30.5 
cm) above the top of the unit under test is not to exceed 0.5 [deg]F per 
foot (0.9 [deg]C per meter). The vertical ambient temperature gradient 
at locations 10 inches (25.4 cm) out from the centers of the two sides 
of the unit being tested is to be maintained during the test. To 
demonstrate that this requirement has been met, test data must include 
measurements taken using temperature sensors at locations 10 inches 
(25.4 cm) from the center of the two sides of the unit under test at 
heights of 2 inches (5.1 cm) and 36 inches (91.4 cm) above the floor or 
supporting platform and at a height of 1 foot (30.5 cm) above the unit 
under test.
    2.1.3 Platform. A platform must be used if the floor temperature is 
not within 3 [deg]F (1.7

[[Page 345]]

[deg]C) of the measured ambient temperature. If a platform is used, it 
is to have a solid top with all sides open for air circulation 
underneath, and its top shall extend at least 1 foot (30.5 cm) beyond 
each side and front of the unit under test and extend to the wall in the 
rear.
    2.2 Operational Conditions. The freezer shall be installed and its 
operating conditions maintained in accordance with HRF-1-2008 
(incorporated by reference; see Sec. 430.3), sections 5.3.2 through 
section 5.5.5.5 (but excluding sections 5.5.5.2 and 5.5.5.4). The quick 
freeze option shall be switched off except as specified in section 3.1 
of this appendix. Additional clarifications are noted in sections 2.3 
through 2.9 of this appendix.
    2.3 Anti-Sweat Heaters. The anti-sweat heater switch is to be on 
during one test and off during a second test. In the case of a freezer 
with variable anti-sweat heater control, the standard cycle energy use 
shall be the result of the calculation described in 6.2.3.
    2.4 The cabinet and its refrigerating mechanism shall be assembled 
and set up in accordance with the printed consumer instructions supplied 
with the cabinet. Set-up of the freezer shall not deviate from these 
instructions, unless explicitly required or allowed by this test 
procedure. Specific required or allowed deviations from such set-up 
include the following:
    (a) Connection of water lines and installation of water filters are 
not required;
    (b) Clearance requirements from surfaces of the product shall be as 
described in section 2.6 below;
    (c) The electric power supply shall be as described in HRF-1-2008 
(incorporated by reference; see Sec. 430.3) section 5.5.1;
    (d) Temperature control settings for testing shall be as described 
in section 3 of this appendix. Settings for special compartments shall 
be as described in section 2.5 of this appendix;
    (e) The product does not need to be anchored or otherwise secured to 
prevent tipping during energy testing;
    (f) All the product's chutes and throats required for the delivery 
of ice shall be free of packing, covers, or other blockages that may be 
fitted for shipping or when the icemaker is not in use; and
    (g) Ice storage bins shall be emptied of ice.
    For cases in which set-up is not clearly defined by this test 
procedure, manufacturers must submit a petition for a waiver (see 
section 7).
    2.5 Special compartments shall be tested with controls set to 
provide the coldest temperature. However, for special compartments in 
which temperature control is achieved using the addition of heat 
(including resistive electric heating, refrigeration system waste heat, 
or heat from any other source, but excluding the transfer of air from 
another part of the interior of the product) for any part of the 
controllable temperature range of that compartment, the product energy 
use shall be determined by averaging two sets of tests. The first set of 
tests shall be conducted with such special compartments at their coldest 
settings, and the second set of tests shall be conducted with such 
special compartments at their warmest settings. The requirements for the 
warmest or coldest temperature settings of this section do not apply to 
features or functions associated with temperature control (such as quick 
freeze) that are initiated manually and terminated automatically within 
168 hours.
    Movable subdividing barriers that separate compartments of different 
types (e.g., fresh food on one side and cooler on the other side) shall 
be placed in the median position. If such a subdividing barrier has an 
even number of positions, the near-median position representing the 
smallest volume of the warmer compartment(s) shall be used.
    2.6 Rear Clearance.
    (a) General. The space between the lowest edge of the rear plane of 
the cabinet and a vertical surface (the test room wall or simulated 
wall) shall be the minimum distance in accordance with the 
manufacturer's instructions, unless other provisions of this section 
apply. The rear plane shall be considered to be the largest flat surface 
at the rear of the cabinet, excluding features that protrude beyond this 
surface, such as brackets or compressors.
    (b) Maximum clearance. The clearance shall not be greater than 2 
inches (51 mm) from the lowest edge of the rear plane to the vertical 
surface, unless the provisions of subsection (c) of this section apply.
    (c) If permanent rear spacers or other components that protrude 
beyond the rear plane extend further than the 2 inch (51 mm) distance, 
or if the highest edge of the rear plane is in contact with the vertical 
surface when the unit is positioned with the lowest edge of the rear 
plane at or further than the 2 inch (51 mm) distance from the vertical 
surface, the appliance shall be located with the spacers or other 
components protruding beyond the rear plane, or the highest edge of the 
rear plane, in contact with the vertical surface.
    (d) Rear-mounted condensers. If the product has a flat rear-wall-
mounted condenser (i.e., a rear-wall-mounted condenser with all 
refrigerant tube centerlines within 0.25 inches (6.4 mm) of the 
condenser plane), and the area of the condenser plane represents at 
least 25% of the total area of the rear wall of the cabinet, then the 
spacing to the vertical surface may be measured from the lowest edge of 
the condenser plane.
    2.7 Steady State Condition. Steady-state conditions exist if the 
temperature measurements taken at 4-minute intervals or less

[[Page 346]]

during a stabilization period are not changing at a rate greater than 
0.042 [deg]F (0.023 [deg]C) per hour as determined by the applicable 
condition of A or B described below.
    A--The average of the measurements during a 2-hour period if no 
cycling occurs or during a number of complete repetitive compressor 
cycles occurring through a period of no less than 2 hours is compared to 
the average over an equivalent time period with 3 hours elapsing between 
the two measurement periods.
    B--If A above cannot be used, the average of the measurements during 
a number of complete repetitive compressor cycles occurring through a 
period of no less than 2 hours and including the last complete cycle 
before a defrost period (or if no cycling occurs, the average of the 
measurements during the last 2 hours before a defrost period) are 
compared to the same averaging period before the following defrost 
period.
    2.8 Freezers with Demand-Response Capability. Freezers that have a 
communication module for demand-response functions that is located 
within the cabinet shall be tested with the communication module in the 
configuration set at the factory just before shipping.
    2.9 For products that require the freezer compartment to be loaded 
with packages in accordance with section 5.5.5.3 of HRF-1-2008, the 
number of packages comprising the 75% load shall be determined by 
filling the compartment completely with the packages that are to be used 
for the test, such that the packages fill as much of the usable 
refrigerated space within the compartment as is physically possible, and 
then removing from the compartment a number of packages so that the 
compartment contains 75% of the packages that were placed in the 
compartment to completely fill it. If multiplying the total number of 
packages by 0.75 results in a fraction, the number of packages used 
shall be rounded to the nearest whole number, rounding up if the result 
ends in 0.5. For multi-shelf units, this method shall be applied to each 
shelf. For both single- and multi-shelf units, the remaining packages 
shall be arranged as necessary to provide the required air gap and 
thermocouple placement. The number of packages comprising the 100% and 
75% loading conditions shall be recorded in the test data maintained in 
accordance with 10 CFR 429.71.

                        3. Test Control Settings

    3.1 Model with No User Operable Temperature Control. A test shall be 
performed during which the compartment temperature and energy use shall 
be measured. A second test shall be performed with the temperature 
control electrically short circuited to cause the compressor to run 
continuously. If the model has the quick freeze option, this option must 
be used to bypass the temperature control.
    3.2 Model with User Operable Temperature Control. Testing shall be 
performed in accordance with one of the following sections using the 
standardized temperature of 0.0 [deg]F (-17.8 [deg]C).

For the purposes of comparing compartment temperatures with standardized 
temperatures, as described in sections 3.2.1 and 3.2.2, the freezer 
compartment temperature shall be as specified in section 5.1.3.
    3.2.1 A first test shall be performed with all temperature controls 
set at their median position midway between their warmest and coldest 
settings. For mechanical control systems, (a) knob detents shall be 
mechanically defeated if necessary to attain a median setting, and (b) 
the warmest and coldest settings shall correspond to the positions in 
which the indicator is aligned with control symbols indicating the 
warmest and coldest settings. For electronic control systems, the test 
shall be performed with all compartment temperature controls set at the 
average of the coldest and warmest settings; if there is no setting 
equal to this average, the setting closest to the average shall be used. 
If there are two such settings equally close to the average, the higher 
of these temperature control settings shall be used. A second test shall 
be performed with all controls set at either their warmest or their 
coldest setting (not electrically or mechanically bypassed), whichever 
is appropriate, to attempt to achieve compartment temperatures measured 
during the two tests that bound (i.e., one is above and one is below) 
the standardized temperature. If the compartment temperatures measured 
during these two tests bound the standardized temperature, then these 
test results shall be used to determine energy consumption. If the 
compartment temperature measured with all controls set at their coldest 
setting is above the standardized temperature, the tested unit fails the 
test and cannot be rated. If the compartment temperature measured with 
all controls set at their warmest setting is below the standardized 
temperature, then the result of this test alone will be used to 
determine energy consumption. Also see Table 1 of this appendix, which 
summarizes these requirements.

    3.2.2 Alternatively, a first test may be performed with all 
temperature controls set at their warmest setting. If the compartment 
temperature is below the standardized temperature, then the result of 
this test alone will be used to determine energy consumption. If this 
condition is not met, then the unit shall be tested in accordance with 
section 3.2.1.

                             4. Test Period

    Tests shall be performed by establishing the conditions set forth in 
section 2 and using the control settings as set forth in section 3 
above.
    4.1 Non-automatic Defrost. If the model being tested has no 
automatic defrost system, the test period shall start after steady-state 
conditions (see section 2.7 of this appendix) have been achieved and be 
no less than three hours in duration. During the test period, the 
compressor motor shall complete two or more whole compressor cycles. (A 
whole compressor cycle is a complete ``on'' and a complete ``off'' 
period of the motor.) If no ``off'' cycling occurs, the test period 
shall be three hours. If less than two compressor cycles occur during a 
24-hour period, then a single complete compressor cycle may be used.
    4.2 Automatic Defrost. If the model being tested has an automatic 
defrost system, the test time period shall start after steady-state 
conditions have been achieved and be from one point during a defrost 
period to the same point during the next defrost period. If the model 
being tested has a long-time automatic defrost system, the alternate 
provisions of 4.2.1 may be used. If the model being tested has a 
variable defrost control, the provisions of 4.2.2 shall apply.
    4.2.1 Long-time Automatic Defrost. If the model being tested has a 
long-time automatic defrost system, the two-part test described in this 
section may be used. The first part is a stable period of compressor 
operation that includes no portions of the defrost cycle, such as 
precooling or recovery, that is otherwise the same as the test for a 
unit having no defrost provisions (section 4.1). The second part is 
designed to capture the energy consumed during all of the events 
occurring with the defrost control sequence that are outside of stable 
operation.
    4.2.1.1 Cycling Compressor System. For a system with a cycling 
compressor, the second part of the test starts at the termination of the 
last regular compressor ``on'' cycle. The average temperature of the 
compartment measured from the termination of the previous compressor 
``on'' cycle to the termination of the last regular compressor ``on'' 
cycle must be within 0.5 [deg]F (0.3 [deg]C) of the average temperature 
of the compartment measured for the first part of the test. If any 
compressor cycles occur prior to the defrost heater being energized that 
cause the average temperature in the compartment to deviate from the 
average temperature for the first part of the test by more than 0.5 
[deg]F (0.3 [deg]C), these compressor cycles are not considered regular 
compressor cycles and must be included in the second part of the test. 
As an example, a ``precooling'' cycle, which is an extended compressor 
cycle that lowers the compartment temperature prior to energizing the 
defrost heater, must be included in the second part of the test. The 
test period for the second part of the test ends at the termination of 
the first regular compressor ``on'' cycle after the compartment 
temperatures have fully recovered to their stable conditions. The 
average temperature of the compartment measured from this termination of 
the first regular compressor ``on'' cycle until the termination of the 
next regular compressor ``on'' cycle must be within 0.5 [deg]F (0.3 
[deg]C) of the average temperature of the compartment measured for the 
first part of the test. See Figure 1. Note that Figure 1 illustrates the 
concepts of precooling and recovery but does not represent all possible 
defrost cycles.

    4.2.1.2 Non-cycling Compressor System. For a system with a non-
cycling compressor, the second part of the test starts at a time before 
defrost during stable operation when the compartment temperature is 
within 0.5 [deg]F (0.3 [deg]C) of the average temperature of the 
compartment measured for the first part of the test. The second part 
stops at a time after defrost during stable operation when the 
compartment temperature is within 0.5 [deg]F (0.3 [deg]C) of the average 
temperature of the compartment measured for the first part of the test. 
See Figure 2.

[[Page 349]]

[GRAPHIC] [TIFF OMITTED] TR25JA12.008

    4.2.2 Variable Defrost Control. If the model being tested has a 
variable defrost control system, the test shall consist of the same two 
parts as the test for long-time automatic defrost (section 4.2.1).

                          5. Test Measurements

    5.1 Temperature Measurements. (a) Temperature measurements shall be 
made at the locations prescribed in Figure 5.2 of HRF-1-2008 
(incorporated by reference; see Sec. 430.3) and shall be accurate to 
within 0.5 [deg]F (0.3 [deg]C).
    (b) If the interior arrangements of the unit under test do not 
conform with those shown in Figure 5.2 of HRF-1-2008, the unit must be 
tested by relocating the temperature sensors from the locations 
specified in the figures to avoid interference with hardware or 
components within the unit, in which case the specific locations used 
for the temperature sensors shall be noted in the test data records 
maintained by the manufacturer in accordance with 10 CFR 429.71, and the 
certification report shall indicate that non-standard sensor locations 
were used. If any temperature sensor is relocated by any amount from the 
location prescribed in Figure 5.2 of HRF-1-2008 in order to maintain a 
minimum 1-inch air space from adjustable shelves or other components 
that could be relocated by the consumer, except in cases in which the 
Figure prescribe a temperature sensor location within 1 inch of a shelf 
or similar feature, this constitutes a relocation of temperature sensors 
that must be recorded in the test data and reported in the certification 
report as described above.
    5.1.1 Measured Temperature. The measured temperature is to be the 
average of all sensor temperature readings taken at a particular point 
in time. Measurements shall be taken at regular intervals not to exceed 
4 minutes.
    5.1.2 Compartment Temperature. The compartment temperature for each 
test period shall be an average of the measured temperatures taken in a 
compartment during the test period as defined in section 4 of

[[Page 350]]

this appendix. For long-time automatic defrost models, compartment 
temperature shall be that measured in the first part of the test period 
specified in section 4.2.1 of this appendix. For models with variable 
defrost controls, compartment temperature shall be that measured in the 
first part of the test period specified in section 4.2.2 of this 
appendix. For models with automatic defrost that is neither long-time 
nor variable defrost, the compartment temperature shall be an average of 
the measured temperatures taken in a compartment during a stable period 
of compressor operation that (a) includes no defrost cycles or events 
associated with a defrost cycle, such as precooling or recovery, (b) is 
no less than three hours in duration, and (c) includes two or more whole 
compressor cycles. If the compressor does not cycle, the stable period 
used for the temperature average shall be three hours in duration.
    5.1.3 Freezer Compartment Temperature. The freezer compartment 
temperature shall be calculated as:
[GRAPHIC] [TIFF OMITTED] TR18JY16.011

Where:

F is the total number of applicable freezer compartments, which include 
          the primary freezer compartment and any number of separate 
          auxiliary freezer compartments;
TFi is the compartment temperature of freezer compartment 
          ``i'' determined in accordance with section 5.1.2 of this 
          appendix; and
VFi is the volume of freezer compartment ``i''.

    5.2 Energy Measurements:
    5.2.1 Per-Day Energy Consumption. The energy consumption in 
kilowatt-hours per day for each test period shall be the energy expended 
during the test period as specified in section 4 adjusted to a 24-hour 
period. The adjustment shall be determined as follows:
    5.2.1.1 Nonautomatic and Automatic Defrost Models. The energy 
consumption in kilowatt-hours per day shall be calculated equivalent to:

ET = (EP x 1440 x K) / T

Where:

ET = test cycle energy expended in kilowatt-hours per day;
EP = energy expended in kilowatt-hours during the test period;
T = length of time of the test period in minutes;
1440 = conversion factor to adjust to a 24-hour period in minutes per 
          day; and
K = dimensionless correction factor of 0.7 for chest freezers and 0.85 
          for upright freezers to adjust for average household usage.

    5.2.1.2 Long-time Automatic Defrost. If the two-part test method is 
used, the energy consumption in kilowatt-hours per day shall be 
calculated equivalent to:

ET = (1440 x K x EP1/T1) + (EP2-(EP1 x T2/T1)) x K x (12/CT)

Where:

ET, 1440, and K are defined in section 5.2.1.1;
EP1 = energy expended in kilowatt-hours during the first part of the 
          test;
EP2 = energy expended in kilowatt-hours during the second part of the 
          test;
CT = defrost timer run time or compressor run time between defrosts in 
          hours required to cause it to go through a complete cycle, 
          rounded to the nearest tenth of an hour;
12 = conversion factor to adjust for a 50 percent run time of the 
          compressor in hours per day; and
T1 and T2 = length of time in minutes of the first and second test parts 
          respectively.

    5.2.1.3 Variable Defrost Control. The energy consumption in 
kilowatt-hours per day shall be calculated equivalent to:

ET = (1440 x K x EP1/T1) + (EP2-(EP1 x T2/T1)) x K x (12/CT),

Where:

ET, 1440, and K are defined in section 5.2.1.1 and EP1, EP2, T1, T2, and 
          12 are defined in section 5.2.1.2;
CT = (CTL x CTM)/(F x (CTM - 
          CTL) + CTL);
CTL = the shortest compressor run time between defrosts used 
          in the variable defrost control algorithm (greater than or 
          equal to 6 but less than or equal to 12 hours), or the 
          shortest compressor run time between defrosts observed for the 
          test (if it is shorter than the shortest run time used in the 
          control algorithm and is greater than 6 hours), or 6 hours (if 
          the shortest observed run time is less than 6 hours), in hours 
          rounded to the nearest tenth of an hour;
CTM = maximum compressor run time between defrosts in hours 
          rounded to the

[[Page 351]]

          nearest tenth of an hour (greater than CTL but not 
          more than 96 hours);
F = ratio of per day energy consumption in excess of the least energy 
          and the maximum difference in per-day energy consumption and 
          is equal to 0.20.

    For variable defrost models with no values for CTL and 
CTM in the algorithm, the default values of 6 and 96 shall be 
used, respectively.
    5.3 Volume Measurements. (a) The unit's total refrigerated volume, 
VT, shall be measured in accordance with HRF-1-2008 (incorporated by 
reference; see Sec. 430.3), section 3.30 and sections 4.2 through 4.3. 
The measured volume shall include all spaces within the insulated volume 
of each compartment except for the volumes that must be deducted in 
accordance with section 4.2.2 of HRF-1-2008, as provided in paragraph 
(b) of this section.
    (b) The following component volumes shall not be included in the 
compartment volume measurements: Icemaker compartment insulation, 
fountain recess, dispenser insulation, and ice chute (if there is a 
plug, cover, or cap over the chute per Figure 4-2 of HRF-1-2008). The 
following component volumes shall be included in the compartment volume 
measurements: Icemaker auger motor (if housed inside the insulated space 
of the cabinet), icemaker kit, ice storage bin, and ice chute (up to the 
dispenser flap, if there is no plug, cover, or cap over the ice chute 
per Figure 4-3 of HRF-1-2008).
    (c) Total refrigerated volume is determined by physical measurement 
of the test unit. Measurements and calculations used to determine the 
total refrigerated volume shall be retained as part of the test records 
underlying the certification of the basic model in accordance with 10 
CFR 429.71.
    (d) Compartment classification shall be based on subdivision of the 
refrigerated volume into zones separated from each other by subdividing 
barriers: No evaluated compartment shall be a zone of a larger 
compartment unless the zone is separated from the remainder of the 
larger compartment by subdividing barriers; if there are no such 
subdividing barriers within the larger compartment, the larger 
compartment must be evaluated as a single compartment rather than as 
multiple compartments. If the cabinet contains a movable subdividing 
barrier, it must be placed as described in section 2.5 of this appendix.
    (e) Freezer compartment volumes shall be calculated and recorded to 
the nearest 0.01 cubic feet. Total refrigerated volume shall be 
calculated and recorded to the nearest 0.1 cubic feet.

        6. Calculation of Derived Results From Test Measurements

    6.1 Adjusted Total Volume. The adjusted total volume of each tested 
unit must be determined based upon the volume measured in section 5.3 of 
this appendix using the following calculations. Where volume 
measurements for the freezer are recorded in liters, the measured volume 
must be converted to cubic feet and rounded to the nearest 0.01 cubic 
foot prior to calculating the adjusted volume. Adjusted total volume 
shall be calculated and recorded to the nearest 0.1 cubic foot. The 
adjusted total volume, AV, for freezers under test shall be defined as:

AV = VT x CF

Where:

VA = adjusted total volume in cubic feet;
VT = total refrigerated volume in cubic feet; and
CF = dimensionless correction factor of 1.76.

    6.2 Average Per-Cycle Energy Consumption. The average per-cycle 
energy consumption for a cycle type, E, is expressed in kilowatt-hours 
per cycle to the nearest one hundredth (0.01) kilowatt-hour, and shall 
be calculated according to the sections below.
    6.2.1 If the compartment temperature is always below 0.0 [deg]F (-
17.8 [deg]C), the average per-cycle energy consumption shall be 
equivalent to:

E = ET1 + IET

Where:

E = total per-cycle energy consumption in kilowatt-hours per day;
ET is defined in section 5.2.1 of this appendix;
The number 1 indicates the test during which the highest compartment 
          temperature is measured; and
IET, expressed in kilowatt-hours per cycle, equals 0.23 for a product 
          with an automatic icemaker and otherwise equals 0 (zero).

    6.2.2 If one of the compartment temperatures measured for a test is 
greater than 0.0 [deg]F (17.8 [deg]C), the average per-cycle energy 
consumption shall be equivalent to:

E = ET1 + ((ET2 - ET1) x (0.0 - TF1)/(TF2 - TF1)) + IET

Where:

E and IET are defined in section 6.2.1 of this appendix and ET is 
          defined in section 5.2.1 of this appendix;
TF = freezer compartment temperature determined according to section 
          5.1.3 of this appendix in degrees F;
The numbers 1 and 2 indicate measurements taken during the two tests to 
          be used to calculate energy consumption, as specified in 
          section 3 of this appendix; and
0.0 = standardized compartment temperature in degrees F.


[[Page 352]]


    6.2.3 Variable Anti-Sweat Heater Models. The standard cycle energy 
consumption of a freezer with a variable anti-sweat heater control 
(Estd), expressed in kilowatt-hours per day, shall be 
calculated equivalent to:

Estd = E + (Correction Factor) where E is determined by 
          6.2.1, or 6.2.2, whichever is appropriate, with the anti-sweat 
          heater switch in the ``off'' position or, for a product 
          without an anti-sweat heater switch, the anti-sweat heater in 
          its lowest energy use state.
Correction Factor = (Anti-sweat Heater Power x System-loss Factor) x (24 
          hrs/1 day) x (1 kW/1000 W)

Where:

Anti-sweat Heater Power = 0.034 * (Heater Watts at 5%RH)
 + 0.211 * (Heater Watts at 15%RH)
 + 0.204 * (Heater Watts at 25%RH)
 + 0.166 * (Heater Watts at 35%RH)
 + 0.126 * (Heater Watts at 45%RH)
 + 0.119 * (Heater Watts at 55%RH)
 + 0.069 * (Heater Watts at 65%RH)
 + 0.047 * (Heater Watts at 75%RH)
 + 0.008 * (Heater Watts at 85%RH)
 + 0.015 * (Heater Watts at 95%RH)
Heater Watts at a specific relative humidity = the nominal watts used by 
          all heaters at that specific relative humidity, 72 [deg]F 
          ambient (22.2 [deg]C), and DOE reference freezer (FZ) average 
          temperature of 0 [deg]F (-17.8 [deg]C).
System-loss Factor = 1.3

                        7. Test Procedure Waivers

    To the extent that the procedures contained in this appendix do not 
provide a means for determining the energy consumption of a basic model, 
a manufacturer must obtain a waiver under Sec. 430.27 to establish an 
acceptable test procedure for each such basic model. Such instances 
could, for example, include situations where the test set-up for a 
particular basic model is not clearly defined by the provisions of 
section 2 of this appendix. For details regarding the criteria and 
procedures for obtaining a waiver, please refer to Sec. 430.27.

             Measuring the Energy Consumption of Dishwashers

    Note: Manufacturers must test all dishwashers using the provisions 
of Appendix C1 to certify compliance with energy conservation standards 
and to make any other representations related to energy and/or water 
consumption.
    After the compliance date for any amended energy conservation 
standards that incorporate standby mode and off mode energy consumption 
(May 30, 2013 unless the direct final rule published on May 30, 2012 is 
withdrawn), all dishwashers shall be tested using the provisions of 
Appendix C1 to certify compliance with amended energy conservation 
standards and to make any representations related to energy and/or water 
consumption, with the following exception. If the compliance date is 
before April 29, 2013, manufacturers may use Appendix C for any 
representations until April 29, 2013 of energy and/or water consumption 
of these products, consistent with the requirements of 42 U.S.C. 
6293(c)(2).

                             1. Definitions

    1.1 Active mode means a mode in which the dishwasher is connected to 
a mains power source, has been activated, and is performing one of the 
main functions of washing, rinsing, or drying (when a drying process is 
included) dishware, glassware, eating utensils, and most cooking 
utensils by chemical, mechanical, and/or electrical means, or is 
involved in functions necessary for these main functions, such as

    1.12 Normal cycle means the cycle type, including washing and drying 
temperature options, recommended in the manufacturer's instructions for 
daily, regular, or typical use to completely wash a full load of 
normally soiled dishes including the power-dry feature. If no cycle or 
more than one cycle is recommended in the manufacturer's instructions 
for daily, regular, or typical use to completely wash a full load of 
normally soiled dishes, the most energy intensive of these cycles shall 
be considered the normal cycle. In the absence of a manufacturer 
recommendation on washing and drying temperature options, the highest 
energy consumption options must be selected.
    1.13 Off mode means a mode in which the dishwasher is connected to a 
mains power source and is not providing any active mode or standby mode 
function, and where the mode may persist for an indefinite time. An 
indicator that only shows the user that the product is in the off 
position is included within the classification of an off mode.
    1.14 Power-dry feature means the introduction of electrically-
generated heat into the washing chamber for the purpose of improving the 
drying performance of the dishwasher.

of this appendix.
    1.18 Sensor medium response means, for standard dishwashers, the set 
of operations in a soil-sensing dishwasher for completely washing a load 
of dishes, two place settings of which are soiled according to ANSI/AHAM 
DW-1-2010 (incorporated by reference; see Sec. 430.3) and as 
additionally specified in section 2.7 of this appendix. For compact 
dishwashers, this definition is the same, except that one soiled place 
setting is used instead of two.

oriented or protective functions which may persist for an indefinite 
time: (a) To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch (including 
remote control), internal sensor, or timer; (b) continuous functions, 
including information or status displays (including clocks) or sensor-
based functions. A timer is a continuous clock function (which may or 
may not be associated with a display) that provides regular scheduled

                     4. Test Cycle and Measurements

    4.1 Active mode cycle. Perform a test cycle by establishing the 
testing conditions set forth in section 2 of this appendix, setting the 
dishwasher to the cycle type to be tested according to section 2.6.1, 
2.6.2, or 2.6.3 of this appendix, initiating the cycle, and allowing the 
cycle to proceed to completion.
    4.1.1 Machine electrical energy consumption. Measure the machine 
electrical energy consumption, M, expressed as the number of kilowatt-
hours of electricity consumed by the machine during the entire test 
cycle, using a water supply temperature as set forth in section 2.3 of 
this appendix and using a watt-hour meter as specified in section 3.5 of 
this appendix.
    4.1.2 Fan electrical energy consumption. If the dishwasher is 
capable of operation in fan-only mode, measure the fan electrical energy 
consumption, MF, expressed as the number of kilowatt-hours of 
electricity consumed by the machine for the duration of fan-only mode, 
using a watt-hour meter as specified in section 3.5 of this appendix. 
Alternatively, if the duration of fan-only mode is known, the watt-hours 
consumed may be measured for a period of 10 minutes in fan-only mode, 
using a watt-hour meter as specified in section 3.5 of this appendix. 
Multiply this value by the time in minutes that the dishwasher remains 
in fan-only mode, LF, and divide by 10,000 to obtain 
MF. The alternative approach may be used only if the 
resulting MF is representative of energy use during the 
entire fan-only mode.
    4.1.3 Water consumption. Measure the water consumption, V, expressed 
as the number of gallons of water delivered to the machine during the 
entire test cycle, using a water meter specified in section 3.3 of this 
appendix.
    4.2 Standby mode and off mode power. Connect the dishwasher to a 
standby mode and off mode watt meter as specified in section 3.6 of this 
appendix. Establish the testing conditions set forth in sections 2.1, 
2.2, and 2.5.2 of this appendix. For dishwashers that take some time to 
enter a stable state from a higher power state as discussed in Section 
5, Paragraph 5.1, note 1 of IEC 62301 (incorporated by reference; see 
Sec. 430.3), allow sufficient time for the dishwasher to reach the 
lower power state before proceeding with the test measurement. Follow 
the test procedure specified in Section 5, Paragraph 5.3.2 of IEC 62301 
for testing in each possible mode as described in sections 4.2.1 and 
4.2.2 of this appendix.
    4.2.1 If the dishwasher has an inactive mode, as defined in section 
1.10 of this appendix, measure and record the average inactive mode 
power of the dishwasher, PIA, in watts.
    4.2.2 If the dishwasher has an off mode, as defined in section 1.13 
of this appendix, measure and record the average off mode power, 
POM, in watts.

        5. Calculation of Derived Results From Test Measurements

    5.1 Machine energy consumption.
    5.1.1 Machine energy consumption for non-soil-sensing electric 
dishwashers. Take the value recorded in section 4.1.1 of this appendix 
as the per-cycle machine electrical energy consumption. Express the 
value, M, in kilowatt-hours per cycle.
    5.1.2 Machine energy consumption for soil-sensing electric 
dishwashers. The machine energy consumption for the sensor normal cycle, 
M, is defined as:

M = (Mhr x Fhr) + (Mmr x 
          Fmr) + (Mlr x Flr)

where,

Mhr = the value recorded in section 4.1.1 of this appendix 
          for the test of the sensor heavy response, expressed in 
          kilowatt-hours per cycle,
Mmr = the value recorded in section 4.1.1 of this appendix 
          for the test of the sensor medium response, expressed in 
          kilowatt-hours per cycle,
Mlr = the value recorded in section 4.1.1 of this appendix 
          for the test of the sensor light response, expressed in 
          kilowatt-hours per cycle,
Fhr = the weighting factor based on consumer use of heavy 
          response = 0.05,
Fmr = the weighting factor based on consumer use of medium

   Sec. Appendix D to Subpart B of Part 430--Uniform Test Method for 
           Measuring the Energy Consumption of Clothes Dryers

    Note: Effective February 10, 2014, manufacturers must make 
representations of energy efficiency, including certifications of 
compliance, using appendix D. Compliance with DOE's amended standards 
for clothes dryers, and corresponding use of the test procedures at 
appendix D1 for all representations, including certifications of 
compliance, is required as of January 1, 2015. Manufacturers must use a 
single appendix for all representations, including certifications of 
compliance, and may not use appendix D for certain representations and 
appendix D1 for other representations. The procedures in appendix D2 
need not be performed to determine compliance with energy conservation 
standards for clothes dryers at this time. However, manufacturers may 
elect to use the amended appendix D, D1 or D2 early.

                             1. Definitions

when the added gas or electric heat is terminated and the clothes 
continue to tumble and dry within the drum.
    1.5 ``Cycle'' means a sequence of operation of a clothes dryer which 
performs a clothes drying operation, and may include variations or 
combinations of the functions of heating, tumbling and drying.

4.4 cubic feet or greater.
    1.10 ``Moisture content'' means the ratio of the weight of water 
contained by the test load to the bone-dry weight of the test load, 
expressed as a percent.

[[Page 361]]

    1.11 ``Automatic termination control'' means a dryer control system 
with a sensor which monitors either the dryer load temperature or its 
moisture content and with a controller which automatically terminates 
the drying process. A mark or detent which indicates a preferred 
automatic termination control setting must be present if the dryer is to 
be classified as having an ``automatic termination control.'' A mark is 
a visible single control setting on one or more dryer controls.
    1.12 ``Temperature sensing control'' means a system which monitors 
dryer exhaust air temperature and automatically terminates the dryer 
cycle.

    2.1 Installation. Install the clothes dryer in accordance with 
manufacturer's instructions as shipped with the unit. If the 
manufacturer's instructions do not specify the installation requirements 
for a certain component, it shall be tested in the as-shipped condition. 
The dryer exhaust shall be restricted by adding the AHAM exhaust 
simulator described in 3.3.5 of HLD-1. All external joints should be 
taped to avoid air leakage. Disconnect all lights, such as task lights, 
that do not provide any information related to the drying process on the

the value recommended by the manufacturer in the installation manual, on 
the nameplate sticker, or wherever the manufacturer makes such a 
recommendation for the basic model. The hourly Btu rating of the burner 
shall be maintained within 5 percent of the rating 
specified by the manufacturer. If the requirement to maintain the hourly 
Btu rating of the burner within 5 percent of the 
rating specified by the manufacturer cannot be achieved under the 
allowable range in gas inlet test pressure, the orifice of the gas 
burner should be modified as necessary to achieve the required Btu 
rating. The natural gas supplied should have a heating value of 
approximately 1,025 Btus per standard cubic foot. The actual heating 
value, Hn2, in Btus per standard cubic foot, for the natural 
gas to be used in the test shall be obtained either from measurements 
made by the manufacturer conducting the test using a standard continuous 
flow calorimeter as described in section 2.4.6 or by the purchase of 
bottled natural gas whose Btu rating is certified to be at least as 
accurate a rating as could be obtained from measurements with a standard 
continuous flow calorimeter as described in section 2.4.6.
    2.3.2.2 Propane gas. Maintain the gas supply to the clothes dryer at

13 inches of water column. If the clothes dryer is equipped with a gas 
appliance pressure regulator, the regulator outlet pressure at the 
normal test pressure shall be within 10 percent of 
the value recommended by the manufacturer in the installation manual, on 
the nameplate sticker, or wherever the manufacturer makes such a 
recommendation for the basic model. The hourly Btu rating of the burner 
shall be maintained within 5 percent of the rating 
specified by the manufacturer. If the requirement to maintain the hourly 
Btu rating of the burner within 5 percent of the 
rating specified by the manufacturer cannot be achieved under the 
allowable range in gas inlet test pressure, the orifice of the gas 
burner should be modified as necessary to achieve the required Btu 
rating. The propane gas supplied should have a heating value of 
approximately 2,500 Btus per standard cubic foot. The actual heating 
value, Hp, in Btus per standard cubic foot, for the propane 
gas to be used in the test shall be obtained either from measurements 
made by the manufacturer conducting the test using a standard continuous 
flow calorimeter as described in section 2.4.6 or by the purchase of 
bottled gas whose Btu rating is certified to be at least as accurate a 
rating as could be obtained from measurement with a standard continuous 
calorimeter as described in section 2.4.6.

per million hardness for approximately two minutes in order to saturate 
the fabric. Then, extract water from the wet test load by spinning the 
load until the moisture content of the load is between 66.5 percent to 
73.5 percent of the bone-dry weight of the test load.
    2.7.3 Method of loading. Load the energy test cloths by grasping 
them in the center,

[[Page 363]]

shaking them to hang loosely and then dropping them in the dryer at 
random.
    2.8 Clothes dryer preconditioning. Before any test cycle, operate 
the dryer without a test load in the non-heat mode for 15 minutes or 
until the discharge air temperature is varying less than 1 [deg]F for 10 
minutes, which ever is longer, in the test installation location with 
the ambient conditions within the specified rest condition tolerances of 
2.2.

                   3. Test Procedures and Measurements

    3.1 Drum Capacity. Measure the drum capacity by sealing all openings 
in the drum except the loading port with a plastic bag, and ensure that 
all corners and depressions are filled and that there are no extrusions 
of the plastic bag through any openings in the interior of the drum. 
Support the dryer's rear drum surface on a platform scale to prevent 
deflection of the dryer, and record the weight of the empty dryer. Fill 
the drum with water to a level determined by the intersection of the 
door plane and the loading port (i.e., the uppermost edge of the drum 
that is in contact with the door seal). Record the temperature of the 
water and then the weight of the dryer with the added water and then 
determine the mass of the water in pounds. Add the appropriate volume to 
account for any space in the drum interior not measured by water fill 
(e.g., the space above the uppermost edge of the drum within a curved 
door) and subtract the appropriate volume to account for space that is 
measured by water fill but cannot be used when the door is closed (e.g., 
space occupied by the door when closed). The drum capacity is calculated 
as follows:
C = w/d volume adjustment
C = capacity in cubic feet.
w = mass of water in pounds.
d = density of water at the measured temperature in pounds per cubic 
          foot.
    3.2 Dryer loading. Load the dryer as specified in 2.7.
    3.3 Test cycle. Operate the clothes dryer at the maximum temperature 
setting and, if equipped with a timer, at the maximum time setting. Any 
other optional cycle settings that do not affect the temperature or time 
settings shall be tested in the as-shipped position. If the clothes 
dryer does not have a separate temperature setting selection on the 
control panel, the maximum time setting should be used for the drying 
test cycle. Dry the test load until the moisture content of the test 
load is between 2.5 percent and 5.0 percent of the bone-dry weight of 
the test load, but do not permit the dryer to advance into cool down. If 
required, reset the timer or automatic dry control.
    3.4 Data recording. Record for each test cycle:
    3.4.1 Bone-dry weight of the test load described in 2.7.
    3.4.2 Moisture content of the wet test load before the test, as 
described in 2.7.
    3.4.3 Moisture content of the dry test load obtained after the test 
described in 3.3.
    3.4.4 Test room conditions, temperature and percent relative 
humidity described in 2.2.

    3.4.6.1 Total kilowatt-hours of electrical energy, Ete, 
consumed during the test described in 3.3.
    3.4.6.2 Cubic feet of gas per cycle, Etg, consumed during 
the test described in 3.3.
    3.4.6.3 On gas dryers using a continuously burning pilot light--the 
cubic feet of gas, Epg, consumed by the gas pilot light in 
one hour.
    3.4.6.4 Correct the gas heating value, GEF, as measured in 2.3.2.1 
and 2.3.2.2, to standard pressure and temperature conditions in 
accordance with U.S. Bureau of Standards, circular C417, 1938. A sample 
calculation is illustrated in appendix E of HLD-1.
    3.5 Test for automatic termination field use factor credits. Credit 
for automatic termination can be claimed for those dryers which meet the 
requirements for either temperature-sensing control, 1.12, or moisture 
sensing control, 1.13, and having present the appropriate mark or detent 
feed defined in 1.11.

           Measuring the Energy Consumption of Clothes Dryers

    Note: Effective February 10, 2014, manufacturers must make 
representations of energy efficiency, including certifications of 
compliance, using appendix D. Compliance with DOE's amended standards 
for clothes dryers, and corresponding use of the test procedures at 
appendix D1 for all representations, including certifications of 
compliance, is required as of January 1, 2015. Manufacturers must use a 
single appendix for all representations, including certifications of 
compliance, and may not use appendix D for certain representations and 
appendix D1 for other representations. The procedures in appendix D2 
need not be performed to determine compliance with energy conservation 
standards for clothes dryers at this time. However, manufacturers may 
elect to use the amended appendix D, D1, or D2 early.

                          2. Testing Conditions

    2.1 Installation.
    2.1.1 All clothes dryers. For both conventional clothes dryers and 
ventless clothes dryers, as defined in sections 1.7 and 1.19 of this 
appendix, install the clothes dryer in accordance with manufacturer's 
instructions as shipped with the unit. If the manufacturer's 
instructions do not specify the installation requirements for a certain 
component, it shall be tested in the as-shipped condition. Where the 
manufacturer gives the option to use the dryer both with and without a 
duct, the dryer shall be tested without the exhaust simulator described 
in section 3.3.5.1 of AHAM HLD-1 (incorporated by reference; see Sec. 
430.3). All external joints should be taped to avoid air leakage. For 
drying testing, disconnect all lights, such as task lights, that do not 
provide any information related to the drying process on the clothes 
dryer and that do not consume more than 10 watts during the clothes 
dryer test cycle. Control setting indicator lights showing the cycle 
progression, temperature or dryness settings, or other cycle functions 
that cannot be turned off during the test cycle shall not be 
disconnected during the active mode test cycle. For standby and off mode 
testing, the clothes dryer shall also be installed in accordance with 
section 5, paragraph 5.2 of IEC 62301 (Second Edition) (incorporated by 
reference; see Sec. 430.3), disregarding the provisions regarding 
batteries and the determination, classification, and testing of relevant 
modes. For standby and off mode testing, all lighting systems shall 
remain connected.
    2.1.2 Conventional clothes dryers. For conventional clothes dryers, 
as defined in section 1.7 of this appendix, the dryer exhaust shall be 
restricted by adding the AHAM exhaust simulator described in section 
3.3.5.1 of AHAM HLD-1 (incorporated by reference; see Sec. 430.3).
    2.1.3 Ventless clothes dryers. For ventless clothes dryers, as 
defined in section 1.19, the dryer shall be tested without the AHAM 
exhaust simulator. If the manufacturer gives the option to use a 
ventless clothes dryer, with or without a condensation box, the dryer 
shall be tested with the condensation box installed. For ventless 
clothes dryers, the condenser unit of the dryer must remain in place and 
not be taken out of the dryer for any reason between tests.
    2.2 Ambient temperature and humidity.
    2.2.1 For drying testing, maintain the room ambient air temperature 
at 75 3 [deg]F and the room relative humidity at 
50 10 percent relative humidity.
    2.2.2 For standby and off mode testing, maintain room ambient air 
temperature conditions as specified in section 4, paragraph 4.2 of IEC 
62301 (Second Edition) (incorporated by reference; see Sec. 430.3)
    2.3 Energy supply.
    2.3.1 Electrical supply. Maintain the electrical supply at the 
clothes dryer terminal block within 1 percent of 120/240 or 120/208Y or 
120 volts as applicable to the particular terminal block wiring system 
and within 1 percent of the nameplate frequency as specified by the 
manufacturer. If the dryer has a dual voltage conversion capability, 
conduct the test at the highest voltage specified by the manufacturer.
    2.3.1.1 Supply voltage waveform. For the clothes dryer standby mode 
and off mode

[[Page 366]]

testing, maintain the electrical supply voltage waveform indicated in 
section 4, paragraph 4.3.2 of IEC 62301 (Second Edition) (incorporated 
by reference; see Sec. 430.3). If the power measuring instrument used 
for testing is unable to measure and record the total harmonic content 
during the test measurement period, it is acceptable to measure and 
record the total harmonic content immediately before and after the test 
measurement period.
    2.3.2 Gas supply.
    2.3.2.1 Natural gas. Maintain the gas supply to the clothes dryer 
immediately ahead of all controls at a pressure of 7 to 10 inches of 
water column. If the clothes dryer is equipped with a gas appliance 
pressure regulator for which the manufacturer specifies an outlet 
pressure, the regulator outlet pressure shall be within 10 percent of the value recommended by the manufacturer 
in the installation manual, on the nameplate sticker, or wherever the 
manufacturer makes such a recommendation for the basic model. The hourly 
Btu rating of the burner shall be maintained within 5 percent of the rating specified by the manufacturer. 
If the requirement to maintain the hourly Btu rating of the burner 
within 5 percent of the rating specified by the 
manufacturer cannot be achieved under the allowable range in gas inlet 
test pressure, the orifice of the gas burner should be modified as 
necessary to achieve the required Btu rating. The natural gas supplied 
should have a heating value of approximately 1,025 Btus per standard 
cubic foot. The actual heating value, Hn2, in Btus per 
standard cubic foot, for the natural gas to be used in the test shall be 
obtained either from measurements made by the manufacturer conducting 
the test using a standard continuous flow calorimeter as described in 
section 2.4.6 or by the purchase of bottled natural gas whose Btu rating 
is certified to be at least as accurate a rating as could be obtained 
from measurements with a standard continuous flow calorimeter as 
described in section 2.4.6.
    2.3.2.2 Propane gas. Maintain the gas supply to the clothes dryer 
immediately ahead of all controls at a pressure of 11 to 13 inches of 
water column. If the clothes dryer is equipped with a gas appliance 
pressure regulator for which the manufacturer specifies an outlet 
pressure, the regulator outlet pressure shall be within 10 percent of the value recommended by the manufacturer 
in the installation manual, on the nameplate sticker, or wherever the 
manufacturer makes such a recommendation for the basic model. The hourly 
Btu rating of the burner shall be maintained within 5 percent of the rating specified by the manufacturer. 
If the requirement to maintain the hourly Btu rating of the burner 
within 5 percent of the rating specified by the 
manufacturer cannot be achieved under the allowable range in gas inlet 
test pressure, the orifice of the gas burner should be modified as 
necessary to achieve the required Btu rating. The propane gas supplied 
should have a heating value of approximately 2,500 Btus per standard 
cubic foot. The actual heating value, Hp, in Btus per 
standard cubic foot, for the propane gas to be used in the test shall be 
obtained either from measurements made by the manufacturer conducting 
the test using a standard continuous flow calorimeter as described in 
section 2.4.6 or by the purchase of bottled gas whose Btu rating is 
certified to be at least as accurate a rating as could be obtained from 
measurement with a standard continuous calorimeter as described in 
section 2.4.6.
    2.4 Instrumentation. Perform all test measurements using the 
following instruments as appropriate.
    2.4.1 Weighing scale for test cloth. The scale shall have a range of 
0 to a maximum of 60 pounds with a resolution of at least 0.2 ounces and 
a maximum error no greater than 0.3 percent of any measured value within 
the range of 3 to 15 pounds.
    2.4.1.2 Weighing scale for drum capacity measurements. The scale 
should have a range of 0 to a maximum of 600 pounds with resolution of 
0.50 pounds and a maximum error no greater than 0.5 percent of the 
measured value.
    2.4.2 Kilowatt-hour meter. The kilowatt-hour meter shall have a 
resolution of 0.001 kilowatt-hours and a maximum error no greater than 
0.5 percent of the measured value.
    2.4.3 Gas meter. The gas meter shall have a resolution of 0.001 
cubic feet and a maximum error no greater than 0.5 percent of the 
measured value.
    2.4.4 Dry and wet bulb psychrometer. The dry and wet bulb 
psychrometer shall have an error no greater than 1 
[deg]F. A relative humidity meter with a maximum error tolerance 
expressed in [deg]F equivalent to the requirements for the dry and wet 
bulb psychrometer or with a maximum error tolerance of 2 percent relative humidity would be acceptable for 
measuring the ambient humidity.
    2.4.5 Temperature. The temperature sensor shall have an error no 
greater than 1 [deg]F.
    2.4.6 Standard Continuous Flow Calorimeter. The calorimeter shall 
have an operating range of 750 to 3,500 Btu per cubic feet. The maximum 
error of the basic calorimeter shall be no greater than 0.2 percent of 
the actual heating value of the gas used in the test. The indicator 
readout shall have a maximum error no greater than 0.5 percent of the 
measured value within the operating range and a resolution of 0.2 
percent of the full-scale reading of the indicator instrument.

follows:
    (1) Bone dry the load to a weight change of 1 
percent, or less, as prescribed in section 1.5.
    (2) Place the test cloth load in a standard clothes washer set at 
the maximum water fill level. Wash the load for 10 minutes in soft water 
(17 parts per million hardness or less), using 60.8 grams of AHAM 
standard test detergent Formula 3. Wash water temperature is to be 
controlled at 140 [deg] 5 [deg]F (60 [deg] 2.7 [deg]C). Rinse water temperature is to be controlled 
at 100 [deg] 5 [deg]F (37.7 2.7 [deg]C).
    (3) Rinse the load again at the same water temperature.
    (4) Bone dry the load as prescribed in section 1.5 and weigh the

    (5) This procedure is repeated until there is a weight change of 1 
percent or less.
    (6) A final cycle is to be a hot water wash with no detergent, 
followed by two warm water rinses.
    2.7 Test loads.
    2.7.1 Compact size dryer load. Prepare a bone-dry test load of 
energy cloths which weighs 3.00 pounds .03 pounds. 
Adjustments to the test load to achieve the proper weight can be made by 
the use of energy stuffer cloths, with no more than five stuffer cloths 
per load. Dampen the load by agitating it in water whose temperature is 
60 [deg]F 5 [deg]F and consists of 0 to 17 parts 
per million hardness for approximately 2 minutes in order to saturate 
the fabric. Then, extract water from the wet test load by spinning the 
load until the moisture content of the load is between 54.0-61.0 percent 
of the bone-dry weight of the test load.
    2.7.2 Standard size dryer load. Prepare a bone-dry test load of 
energy cloths which weighs 8.45 pounds .085 
pounds. Adjustments to the test load to achieve the proper weight can be 
made by the use of energy stuffer cloths, with no more than five stuffer 
cloths per load. Dampen the load by agitating it in water whose 
temperature is 60 [deg]F 5 [deg]F and consists of 
0 to 17 parts per million hardness for approximately 2 minutes in order 
to saturate the fabric. Then, extract water from the wet test load by 
spinning the load until the moisture content of the load is between 
54.0-61.0 percent of the bone-dry weight of the test load.
    2.7.3 Method of loading. Load the energy test cloths by grasping

    2.8 Clothes dryer preconditioning.
    2.8.1 Conventional clothes dryers. For conventional clothes dryers, 
before any test cycle, operate the dryer without a test load in the non-
heat mode for 15 minutes or until the discharge air temperature is 
varying less than 1 [deg]F for 10 minutes--whichever is longer--in the 
test installation location with the ambient conditions within the 
specified test condition tolerances of 2.2.
    2.8.2 Ventless clothes dryers. For ventless clothes dryers, before 
any test cycle, the steady-state machine temperature must be equal to 
ambient room temperature described in 2.2.1. This may be done by leaving 
the machine at ambient room conditions for at least 12 hours between 
tests.

                   3. Test Procedures and Measurements

    3.1 Drum Capacity. Measure the drum capacity by sealing all openings 
in the drum except the loading port with a plastic bag, and ensuring 
that all corners and depressions are filled and that there are no 
extrusions of the plastic bag through any openings in the interior of 
the drum. Support the dryer's rear drum surface on a platform scale to 
prevent deflection of the drum surface, and record the weight of the 
empty dryer. Fill the drum with water to a level determined by the 
intersection of the door plane and the loading port (i.e., the uppermost 
edge of the drum that is in contact with the door seal).

[[Page 368]]

Record the temperature of the water and then the weight of the dryer 
with the added water and then determine the mass of the water in pounds. 
Add the appropriate volume to account for any space in the drum interior 
not measured by water fill (e.g., the space above the uppermost edge of 
the drum within a curved door) and subtract the appropriate volume to 
account for space that is measured by water fill but cannot be used when 
the door is closed (e.g., space occupied by the door when closed). The 
drum capacity is calculated as follows:

C = w/d volume adjustment
C = capacity in cubic feet.
w = mass of water in pounds.
d = density of water at the measured temperature in pounds per cubic 
          foot.

    3.2 Dryer Loading. Load the dryer as specified in 2.7.
    3.3 Test cycle. Operate the clothes dryer at the maximum temperature 
setting and, if equipped with a timer, at the maximum time setting. Any 
other optional cycle settings that do not affect the temperature or time 
settings shall be tested in the as-shipped position. If the clothes 
dryer does not have a separate temperature setting selection on the 
control panel, the maximum time setting should be used for the drying 
test cycle. Dry the load until the moisture content of the test load is 
between 2.5 and 5.0 percent of the bone-dry weight of the test load, at 
which point the test cycle is stopped, but do not permit the dryer to 
advance into cool down. If required, reset the timer to increase the 
length of the drying cycle. After stopping the test cycle, remove and 
weigh the test load. The clothes dryer shall not be stopped 
intermittently in the middle of the test cycle for any reason. Record 
the data specified by section 3.4 of this appendix. If the dryer 
automatically stops during a cycle because the condensation box is full 
of water, the test is stopped, and the test run is invalid, in which 
case the condensation box shall be emptied and the test re-run from the 
beginning. For ventless dryers, as defined in section 1.19 of this 
appendix, during the time between two cycles, the door of the dryer 
shall be closed except for loading (and unloading).
    3.4 Data recording. Record for each test cycle:
    3.4.1 Bone-dry weight of the test load described in 2.7.
    3.4.2 Moisture content of the wet test load before the test, as 
described in 2.7.
    3.4.3 Moisture content of the dry test load obtained after the test 
described in 3.3.
    3.4.4 Test room conditions, temperature, and percent relative 
humidity described in 2.2.1.
    3.4.5 For electric dryers--the total kilowatt-hours of electric 
energy, Et, consumed during the test described in 3.3.
    3.4.6 For gas dryers:
    3.4.6.1 Total kilowatt-hours of electrical energy, Ete, 
consumed during the test described in 3.3.
    3.4.6.2 Cubic feet of gas per cycle, Etg, consumed during 
the test described in 3.3.
    3.4.6.3 Correct the gas heating value, GEF, as measured in 2.3.2.1 
and 2.3.2.2, to standard pressure and temperature conditions in 
accordance with U.S. Bureau of Standards, circular C417, 1938.
    3.5 Test for automatic termination field use factor. The field use 
factor for automatic termination can be claimed for those dryers which 
meet the requirements for automatic termination control, defined in 1.4.
    3.6 Standby mode and off mode power. Establish the testing 
conditions set forth in Section 2 ``Testing Conditions'' of this 
appendix. For clothes dryers that take some time to enter a stable state 
from a higher power state as discussed in Section 5, Paragraph 5.1, Note 
1 of IEC 62301 (Second Edition) (incorporated by reference; see Sec. 
430.3), allow sufficient time for the clothes dryer to reach the lower 
power state before proceeding with the test measurement. Follow the test 
procedure specified in section 5, paragraph 5.3.2 of IEC 62301 (Second 
Edition) for testing in each possible mode as described in sections 
3.6.1 and 3.6.2 of this appendix.
    3.6.1 If a clothes dryer has an inactive mode, as defined in 1.12, 
measure and record the average inactive mode power of the clothes dryer, 
PIA, in watts.
    3.6.2 If a clothes dryer has an off mode, as defined in 1.15, 
measure and record the average off mode power of the clothes dryer, 
POFF, in watts.

                          2. Testing Conditions

    2.1 Installation.
    2.1.1 All clothes dryers. For both conventional clothes dryers and 
ventless clothes dryers, as defined in sections 1.8 and 1.21 of this 
appendix, install the clothes dryer in accordance with manufacturer's 
instructions as shipped with the unit. If the manufacturer's 
instructions do not specify the installation requirements for a certain 
component, it shall be tested in the as-shipped condition. Where the 
manufacturer gives the option to use the dryer both with and without a 
duct, the dryer shall be tested without the exhaust simulator described 
in section 3.3.5.1 of AHAM HLD-1 (incorporated by reference; see Sec. 
430.3). All external joints should be taped to avoid air leakage. For 
drying testing, disconnect all lights, such as task lights, that do not 
provide any information related to the drying process on the clothes 
dryer and that do not consume more than 10 watts during the clothes 
dryer test cycle. Control setting indicator lights showing the cycle 
progression, temperature or dryness settings, or other cycle functions 
that cannot be turned off during the test cycle shall not be 
disconnected during the active mode test cycle. For standby and off mode 
testing, the clothes dryer shall also be installed in accordance with 
section 5, paragraph 5.2 of IEC 62301 (Second Edition) (incorporated by 
reference; see Sec. 430.3), disregarding the provisions regarding 
batteries and the determination, classification, and testing of relevant 
modes. For standby and off mode testing, all lighting systems shall 
remain connected.
    2.1.2 Conventional clothes dryers. For conventional clothes dryers, 
as defined in section 1.8 of this appendix, the dryer exhaust shall be 
restricted by adding the AHAM exhaust simulator described in section 
3.3.5.1 of AHAM HLD-1 (incorporated by reference; see Sec. 430.3).
    2.1.3 Ventless clothes dryers. For ventless clothes dryers, as 
defined in section 1.21, the dryer shall be tested without the AHAM 
exhaust simulator. If the manufacturer gives the option to use a 
ventless clothes dryer, with or without a condensation box, the dryer 
shall be tested with the condensation box installed. For ventless 
clothes dryers, the condenser unit of the dryer must remain in place and 
not be taken out of the dryer for any reason between tests.
    2.2 Ambient temperature and humidity.
    2.2.1 For drying testing, maintain the room ambient air temperature 
at 75 3 F and the room relative humidity at 50 
10 percent relative humidity.
    2.2.2 For standby and off mode testing, maintain room ambient air 
temperature conditions as specified in section 4, paragraph 4.2 of IEC 
62301 (Second Edition) (incorporated by reference; see Sec. 430.3).
    2.3 Energy supply.
    2.3.1 Electrical supply. Maintain the electrical supply at the 
clothes dryer terminal block within 1 percent of 120/240 or 120/208Y or 
120 volts as applicable to the particular terminal block wiring system 
and within 1 percent of the nameplate frequency as specified by the 
manufacturer. If the dryer has a dual voltage conversion capability, 
conduct the test at the highest voltage specified by the manufacturer.
    2.3.1.1 Supply voltage waveform. For the clothes dryer standby mode 
and off mode testing, maintain the electrical supply voltage waveform 
indicated in section 4, paragraph 4.3.2 of IEC 62301 (Second Edition) 
(incorporated by reference; see Sec. 430.3). If the power measuring 
instrument used for testing is unable to measure and record the total 
harmonic content during the test measurement period, it is acceptable to 
measure and record the total harmonic content immediately before and 
after the test measurement period.
    2.3.2 Gas supply.
    2.3.2.1 Natural gas. Maintain the gas supply to the clothes dryer 
immediately ahead of all controls at a pressure of 7 to 10 inches of 
water column. If the clothes dryer is equipped with a gas appliance 
pressure regulator for which the manufacturer specifies an outlet 
pressure, the regulator outlet pressure shall be within 10 percent of the value recommended by the manufacturer 
in the installation manual, on the nameplate sticker, or wherever the 
manufacturer makes such a recommendation for the basic model. The hourly 
Btu rating of the burner shall be maintained within 5 percent of the rating specified by the manufacturer. 
If the requirement to maintain the hourly Btu rating of the burner 
within 5 percent of the rating specified by the 
manufacturer cannot be achieved under the allowable range in gas inlet 
test pressure, the orifice of the gas burner should be modified as 
necessary to achieve the required Btu rating. The natural gas supplied 
should have a heating value of approximately 1,025 Btus per standard 
cubic foot. The actual heating value, Hn2, in Btus per 
standard cubic foot, for the natural gas to be used in the test shall be 
obtained either from measurements made by the manufacturer conducting 
the test using a standard continuous flow calorimeter as described in 
section 2.4.6 or by the purchase of bottled natural gas whose Btu rating 
is certified to be at least as accurate a rating as could be obtained 
from measurements with a standard continuous flow calorimeter as 
described in section 2.4.6.
    2.3.2.2 Propane gas. Maintain the gas supply to the clothes dryer 
immediately ahead of all controls at a pressure of 11 to 13 inches of 
water column. If the clothes dryer is equipped with a gas appliance 
pressure regulator for which the manufacturer specifies an outlet 
pressure, the regulator outlet pressure

[[Page 372]]

shall be within 10 percent of the value 
recommended by the manufacturer in the installation manual, on the 
nameplate sticker, or wherever the manufacturer makes such a 
recommendation for the basic model. The hourly Btu rating of the burner 
shall be maintained within 5 percent of the rating 
specified by the manufacturer. If the requirement to maintain the hourly 
Btu rating of the burner within 5 percent of the 
rating specified by the manufacturer cannot be achieved under the 
allowable range in gas inlet test pressure, the orifice of the gas 
burner should be modified as necessary to achieve the required Btu 
rating. The propane gas supplied should have a heating value of 
approximately 2,500 Btus per standard cubic foot. The actual heating 
value, Hp, in Btus per standard cubic foot, for the propane 
gas to be used in the test shall be obtained either from measurements 
made by the manufacturer conducting the test using a standard continuous 
flow calorimeter as described in section 2.4.6 or by the purchase of 
bottled gas whose Btu rating is certified to be at least as accurate a 
rating as could be obtained from measurement with a standard continuous 
calorimeter as described in section 2.4.6.
    2.4 Instrumentation. Perform all test measurements using the 
following instruments as appropriate.
    2.4.1 Weighing scale for test cloth. The scale shall have a range of 
0 to a maximum of 60 pounds with a resolution of at least 0.2 ounces and 
a maximum error no greater than 0.3 percent of any measured value within 
the range of 3 to 15 pounds.
    2.4.1.2 Weighing scale for drum capacity measurements. The scale 
should have a range of 0 to a maximum of 600 pounds with resolution of 
0.50 pounds and a maximum error no greater than 0.5 percent of the 
measured value.
    2.4.2 Kilowatt-hour meter. The kilowatt-hour meter shall have a 
resolution of 0.001 kilowatt-hours and a maximum error no greater than

cubic feet and a maximum error no greater than 0.5 percent of the 
measured value.
    2.4.4 Dry and wet bulb psychrometer. The dry and wet bulb 
psychrometer shall have an error no greater than 1 
[deg]F. A relative humidity meter with a maximum error tolerance 
expressed in [deg]F equivalent to the requirements for the dry and wet 
bulb psychrometer or with a maximum error tolerance of 2 percent relative humidity would be acceptable for 
measuring the ambient humidity.
    2.4.5 Temperature. The temperature sensor shall have an error no 
greater than 1 [deg]F.
    2.4.6 Standard Continuous Flow Calorimeter. The calorimeter shall

moisture content of the load is between 52.5 and 57.5 percent of the 
bone-dry weight of the test load. Make a final mass adjustment, such 
that the moisture content is 57.5 percent 0.33 
percent by adding water uniformly distributed among all of the test 
clothes in a very fine spray using a spray bottle.
    2.7.3 Method of loading. Load the energy test cloths by grasping 
them in the center, shaking them to hang loosely, and then dropping them 
in the dryer at random.
    2.8 Clothes dryer preconditioning.
    2.8.1 Conventional clothes dryers. For conventional clothes dryers, 
before any test cycle, operate the dryer without a test load in the non-
heat mode for 15 minutes or until the discharge air temperature is 
varying less than 1 [deg]F for 10 minutes--whichever is longer--in the 
test installation location with the ambient conditions within the 
specified test condition tolerances of 2.2.
    2.8.2 Ventless clothes dryers. For ventless clothes dryers, before 
any test cycle, the steady-state machine temperature must be equal to 
ambient room temperature described in 2.2.1. This may be done by leaving 
the machine at ambient room conditions for at least 12 hours between 
tests.

                   3. Test Procedures and Measurements

    3.1 Drum Capacity. Measure the drum capacity by sealing all openings 
in the drum except the loading port with a plastic bag, and ensuring 
that all corners and depressions are filled and that there are no 
extrusions of the plastic bag through any openings in the interior of 
the drum. Support the dryer's rear drum surface on a platform scale to 
prevent deflection of the drum surface, and record the weight of the 
empty dryer. Fill the drum with water to a level determined by the 
intersection of the door plane and the loading port (i.e., the uppermost 
edge of the drum that is in contact with the door seal). Record the 
temperature of the water and then the weight of the dryer with the added 
water and then determine the mass of the water in pounds. Add the 
appropriate volume to account for any space in the drum interior not 
measured by water fill (e.g., the space above the uppermost edge of the 
drum within a curved door) and subtract the appropriate volume to 
account for the space that is measured by water fill but cannot be used 
when the door is closed (e.g., space occupied by the door when closed). 
The drum capacity is calculated as follows:

C= w/d volume adjustment
C = capacity in cubic feet.
w = mass of water in pounds.
d = density of water at the measured temperature in pounds per cubic 
          foot.
    3.2 Dryer Loading. Load the dryer as specified in 2.7.
    3.3 Test cycle.
    3.3.1 Timer dryers. For timer dryers, as defined in section 1.20 of 
this appendix, operate the clothes dryer at the maximum temperature 
setting and, if equipped with a timer, at the maximum time setting. Any 
other optional cycle settings that do not affect the temperature or time 
settings shall be tested in the as-shipped position. If the clothes 
dryer does not have a separate temperature setting selection on the 
control panel, the maximum time setting should be used for the drying 
test cycle. Dry the load until the moisture content of the test load is 
between 1 and 2.5 percent of the bone-dry weight of the test load, at 
which point the test cycle is stopped, but do not permit the dryer to 
advance into cool down. If required, reset the timer to increase the 
length of the drying cycle. After stopping the test cycle, remove and 
weigh the test load. The clothes dryer shall not be stopped 
intermittently in the middle of the test cycle for any reason. Record 
the data specified by section 3.4 of this appendix. If the dryer 
automatically

[[Page 374]]

stops during a cycle because the condensation box is full of water, the 
test is stopped, and the test run is invalid, in which case the 
condensation box shall be emptied and the test re-run from the 
beginning. For ventless dryers, as defined in section 1.21 of this 
appendix, during the time between two cycles, the door of the dryer 
shall be closed except for loading (and unloading).
    3.3.2 Automatic termination control dryers. For automatic 
termination control dryers, as defined in section 1.5 of this appendix, 
a ``normal'' program shall be selected for the test cycle. For dryers 
that do not have a ``normal'' program, the cycle recommended by the 
manufacturer for drying cotton or linen clothes shall be selected. Where 
the drying temperature setting can be chosen independently of the 
program, it shall be set to the maximum. Where the dryness level setting 
can be chosen independently of the program, it shall be set to the 
``normal'' or ``medium'' dryness level setting. If such designation is 
not provided, then the dryness level shall be set at the mid-point 
between the minimum and maximum settings. Any other optional cycle 
settings that do not affect the program, temperature or dryness settings 
shall be tested in the as-shipped position. Operate the clothes dryer 
until the completion of the programmed cycle, including the cool down 
period. The cycle shall be considered complete when the dryer indicates 
to the user that the cycle has finished (by means of a display, 
indicator light, audible signal, or other signal) and the heater and 
drum/fan motor shuts off for the final time. If the clothes dryer is 
equipped with a wrinkle prevention mode (i.e., that continuously or 
intermittently tumbles the clothes dryer drum after the clothes dryer 
indicates to the user that the cycle has finished) that is activated by 
default in the as-shipped position or if manufacturers' instructions 
specify that the feature is recommended to be activated for normal use, 
the cycle shall be considered complete after the end of the wrinkle 
prevention mode. After the completion of the test cycle, remove and 
weigh the test load. Record the data specified in section 3.4 of this 
appendix. If the final moisture content is greater than 2 percent, the 
test shall be invalid and a new run shall be conducted using the highest 
dryness level setting. If the dryer automatically stops during a cycle 
because the condensation box is full of water, the test is stopped, and 
the test run is invalid, in which case the condensation box shall be 
emptied and the test re-run from the beginning. For ventless dryers, 
during the time between two cycles, the door of the dryer shall be 
closed except for loading (and unloading).
    3.4 Data recording. Record for each test cycle:
    3.4.1 Bone-dry weight of the test load described in 2.7.
    3.4.2 Moisture content of the wet test load before the test, as 
described in 2.7.
    3.4.3 Moisture content of the dry test load obtained after the test 
described in 3.3.
    3.4.4 Test room conditions, temperature, and percent relative 
humidity described in 2.2.1.

consumed during the test described in 3.3.
    3.4.6.2 Cubic feet of gas per cycle, Etg, consumed during 
the test described in 3.3.
    3.4.6.3 Correct the gas heating value, GEF, as measured in 2.3.2.1 
and 2.3.2.2, to standard pressure and temperature conditions in 
accordance with U.S. Bureau of Standards, circular C417, 1938.
    3.4.7 The cycle settings selected, in accordance with section 3.3.2 
of this appendix, for the automatic termination control dryer test.
    3.5 Test for automatic termination field use factor. The field use 
factor for automatic termination can be claimed for those dryers which 
meet the requirements for automatic termination control, defined in 1.4.
    3.6 Standby mode and off mode power. Establish the testing 
conditions set forth in Section 2 ``Testing Conditions'' of this 
appendix. For clothes dryers that take some time to enter a stable state 
from a higher power state as discussed in Section 5, Paragraph 5.1, Note 
1 of IEC 62301 (Second Edition) (incorporated by reference; see Sec. 
430.3), allow sufficient time for the clothes dryer to reach the lower 
power state before proceeding with the test measurement. Follow the test 
procedure specified in section 5, paragraph 5.3.2 of IEC 62301 (Second 
Edition) for testing in each possible mode as described in sections 
3.6.1 and 3.6.2 of this appendix.
    3.6.1 If a clothes dryer has an inactive mode, as defined in section 
1.13 of this appendix, measure and record the average inactive mode 
power of the clothes dryer, PIA, in watts.
    3.6.2 If a clothes dryer has an off mode, as defined in section 1.16 
of this appendix, measure and record the average off mode power of the 
clothes dryer, POFF, in watts.

   Sec. Appendix E to Subpart B of Part 430--Uniform Test Method for 
            Measuring the Energy Consumption of Water Heaters

    Note: After December 31, 2015, any representations made with respect 
to the energy use or efficiency of residential water heaters and 
commercial water heaters covered by this test method must be made in 
accordance with the results of testing pursuant to this appendix. 
(Because the statute permits use of a conversion factor until the later 
of December 31, 2015 or one year after publication of a conversion 
factor final rule, DOE may amend the mandatory compliance date for use 
of this amended test procedure, as necessary.)
    Manufacturers conducting tests of residential water heaters and 
commercial water heaters covered by this test method after July 13, 
2015, and prior to December 31, 2015, must conduct such test in 
accordance with either this appendix or the previous test method. For 
residential water heaters, the previous test method is appendix E as it 
appeared at 10 CFR part 430, subpart B, appendix E, in the 10 CFR parts 
200 to 499 edition revised as of January 1, 2014. For commercial water 
heaters, the previous test method is 10 CFR 431.106 in the 10 CFR parts 
200 to 499 edition revised as of January 1, 2014. Any representations 
made with respect to the energy use or efficiency of such water heaters 
must be in accordance with whichever version is selected.

                             1. Definitions.

    1.1. Cut-in means the time when or water temperature at which a 
water heater control or thermostat acts to increase the energy or fuel 
input to the heating elements, compressor, or burner.
    1.2. Cut-out means the time when or water temperature at which a 
water heater control or thermostat acts to reduce to a minimum the 
energy or fuel input to the heating elements, compressor, or burner.
    1.3. Design Power Rating means the nominal power rating that a water 
heater manufacturer assigns to a particular design of water heater,

    1.5. First-Hour Rating means an estimate of the maximum volume of 
``hot'' water that a storage-type water heater can supply within an hour 
that begins with the water heater fully heated (i.e., with all 
thermostats satisfied). It is a function of both the storage volume and 
the recovery rate.
    1.6. Flow-activated describes an operational scheme in which a water 
heater initiates and terminates heating based on sensing flow.
    1.7. Heat Trap means a device that can be integrally connected or 
independently attached to the hot and/or cold water pipe connections of 
a water heater such that the device will develop a thermal or mechanical 
seal to minimize the recirculation of water due to thermal convection 
between the water heater tank and its connecting pipes.
    1.8. Maximum GPM (L/min) Rating means the maximum gallons per minute 
(liters per minute) of hot water that can be supplied by an 
instantaneous water heater while maintaining a nominal temperature rise 
of 67 [deg]F (37.3 [deg]C) during steady-state operation, as determined 
by testing in accordance with section 5.3.2 of this appendix.
    1.9. Rated Storage Volume means the water storage capacity of a 
water heater, in gallons (liters), as certified by the manufacturer 
pursuant to 10 CFR part 429.
    1.10. Recovery Efficiency means the ratio of energy delivered to the 
water to the energy content of the fuel consumed by the water heater.
    1.11. Recovery Period means the time when the main burner of a 
storage water heater is raising the temperature of the stored water.
    1.12. Standby means the time, in hours, during which water is not 
being withdrawn from the water heater. There are two standby time 
intervals used within this test procedure: [tau]stby,1 
represents the elapsed time between the time at which the maximum mean 
tank temperature is observed after the first draw cluster and the minute 
prior to the start of the first draw following the end of the first draw 
cluster of the 24-hour simulated-use test; [tau]stby,2 
represents the total time during the 24-hour simulated-use test when

1,025 Btu per standard cubic foot (38,190 kJ per standard cubic meter).
    2.7.3 Propane Gas. Maintain the supply pressure in accordance with 
the manufacturer's specifications. If the supply pressure is not 
specified, maintain a supply pressure of 11-13 inches of water column 
(2.7-3.2 kPa). If the water heater is equipped with a gas appliance 
pressure regulator, the regulator outlet pressure shall be within 10% of the manufacturer's specified manifold pressure. 
For all tests, use propane gas with a heating value of approximately 
2,500 Btu per standard cubic foot (93,147 kJ per standard cubic meter).
    2.7.4 Fuel Oil Supply. Maintain an uninterrupted supply of fuel oil. 
Use fuel oil having a heating value of approximately 138,700 Btu per 
gallon (38,660 kJ per liter).

                             4. Installation

    4.1 Water Heater Mounting. A water heater designed to be 
freestanding shall be placed on a \3/4\ inch (2 cm) thick plywood 
platform supported by three 2x4 inch (5 cmx10 cm) runners. If the water 
heater is not approved for installation on combustible flooring, 
suitable non-combustible material shall be placed between the water 
heater and the platform. Counter-top water heaters shall be placed 
against a simulated wall section. Wall-mounted water heaters shall be 
supported on a simulated wall in accordance with the manufacturer-
published installation instructions. When a simulated wall is used, the 
construction shall be 2x4 inch (5 cmx10 cm) studs, faced with \3/4\ inch 
(2 cm) plywood. For heat pump water heaters not delivered as a single 
package, the units shall be connected in accordance with the 
manufacturer-published installation instructions and the overall system 
shall be placed on the above-described plywood platform. If installation 
instructions are not provided by the heat pump manufacturer, uninsulated 
8 foot (2.4 m) long connecting hoses having an inside diameter of \5/8\ 
inch (1.6 cm) shall be used to connect the storage tank and the heat 
pump water heater. The testing of the water heater shall occur in an 
area that is protected from drafts of more than 50 ft/min (0.25 m/s) 
from room ventilation registers, windows, or other external sources of 
air movement.
    4.2 Water Supply. Connect the water heater to a water supply capable 
of delivering water at conditions as specified in sections 2.3 and 2.6 
of this appendix.
    4.3 Water Inlet and Outlet Configuration. For freestanding water 
heaters that are taller than 36 inches (91.4 cm), inlet and outlet 
piping connections shall be configured in a manner consistent with 
Figures 1 and 2 of section 6.4.6 of this appendix. Inlet and outlet 
piping connections for wall-mounted water heaters shall be consistent 
with Figure 3 of section 6.4.6 of this appendix. For freestanding water 
heaters that are 36 inches or less in height and not supplied as part of 
a counter-top enclosure (commonly referred to as an under-the-counter 
model), inlet and outlet piping shall be installed in a manner 
consistent with Figures 4, 5, or 6 of section 6.4.6 of this appendix. 
For water heaters that are supplied with a counter-top enclosure, inlet 
and outlet piping shall be made in a manner consistent with Figures 7a 
and 7b of section 6.4.6 of this appendix, respectively. The vertical 
piping noted in Figures 7a and 7b shall be located (whether inside the 
enclosure or along the outside in a recessed channel) in accordance with 
the manufacturer-published installation instructions.
    All dimensions noted in Figures 1 through 7 of section 6.4.6 of this 
appendix must be

[[Page 380]]

achieved. All piping between the water heater and inlet and outlet 
temperature sensors, noted as TIN and TOUT in the 
figures, shall be Type ``L'' hard copper having the same diameter as the 
connections on the water heater. Unions may be used to facilitate 
installation and removal of the piping arrangements. Install a pressure 
gauge and diaphragm expansion tank in the supply water piping at a 
location upstream of the inlet temperature sensor. Install an 
appropriately rated pressure and temperature relief valve on all water 
heaters at the port specified by the manufacturer. Discharge piping for 
the relief valve must be non-metallic. If heat traps, piping insulation, 
or pressure relief valve insulation are supplied with the water heater, 
they must be installed for testing. Except when using a simulated wall, 
provide sufficient clearance such that none of the piping contacts other 
surfaces in the test room.
    4.4 Fuel and/or Electrical Power and Energy Consumption. Install one 
or more instruments that measure, as appropriate, the quantity and rate 
of electrical energy and/or fossil fuel consumption in accordance with 
section 3 of this appendix.
    4.5 Internal Storage Tank Temperature Measurements. For water 
heaters with rated storage volumes greater than or equal to 20 gallons, 
install six temperature measurement sensors inside the water heater tank 
with a vertical distance of at least 4 inches (100 mm) between 
successive sensors. For water heaters with rated storage volumes between 
2 and 20 gallons, install three temperature measurement sensors inside 
the water heater tank. Position a temperature sensor at the vertical 
midpoint of each of the six equal volume nodes within a tank larger than 
20 gallons or the three equal volume nodes within a tank between 2 and 
20 gallons. Nodes designate the equal volumes used to evenly partition 
the total volume of the tank. As much as is possible, the temperature 
sensor should be positioned away from any heating elements, anodic 
protective devices, tank walls, and flue pipe walls. If the tank cannot 
accommodate six temperature sensors and meet the installation 
requirements specified above, install the maximum number of sensors that 
comply with the installation requirements. Install the temperature 
sensors through: (1) The anodic device opening; (2) the relief valve 
opening; or (3) the hot water outlet. If installed through the relief 
valve opening or the hot water outlet, a tee fitting or outlet piping, 
as applicable, must be installed as close as possible to its original 
location. If the relief valve temperature sensor is relocated, and it no 
longer extends into the top of the tank, install a substitute relief 
valve that has a sensing element that can reach into the tank. If the 
hot water outlet includes a heat trap, install the heat trap on top of 
the tee fitting. Cover any added fittings with thermal insulation having 
an R value between 4 and 8 h[middot]ft\2\[middot] [deg]F/Btu (0.7 and 
1.4 m\2\[middot] [deg]C/W).
    4.6 Ambient Air Temperature Measurement. Install an ambient air 
temperature sensor at the vertical mid-point of the water heater and 
approximately 2 feet (610 mm) from the surface of the water heater. 
Shield the sensor against radiation.
    4.7 Inlet and Outlet Water Temperature Measurements. Install 
temperature sensors in the cold-water inlet pipe and hot-water outlet 
pipe as shown in Figures 1, 2, 3, 4, 5, 6, 7a, and 7b of section 6.4.6 
of this appendix, as applicable.
    4.8 Flow Control. Install a valve or valves to provide flow as 
specified in sections 5.3 and 5.4 of this appendix.
    4.9 Flue Requirements.
    4.9.1 Gas-Fired Water Heaters. Establish a natural draft in the 
following manner. For gas-fired water heaters with a vertically 
discharging draft hood outlet, connect to the draft hood outlet a 5-foot 
(1.5-meter) vertical vent pipe extension with a diameter equal to the 
largest flue collar size of the draft hood. For gas-fired water heaters 
with a horizontally discharging draft hood outlet, connect to the draft 
hood outlet a 90-degree elbow with a diameter equal to the largest flue 
collar size of the draft hood, connect a 5-foot (1.5-meter) length of 
vent pipe to that elbow, and orient the vent pipe to discharge 
vertically upward. Install direct-vent gas-fired water heaters with 
venting equipment specified in the manufacturer's instructions using the 
minimum vertical and horizontal lengths of vent pipe recommended by the 
manufacturer.
    4.9.2 Oil-Fired Water Heaters. Establish a draft at the flue collar 
at the value specified in the manufacturer's instructions. Establish the 
draft by using a sufficient length of vent pipe connected to the water 
heater flue outlet, and directed vertically upward. For an oil-fired 
water heater with a horizontally discharging draft hood outlet, connect 
to the draft hood outlet a 90-degree elbow with a diameter equal to the 
largest flue collar size of the draft hood, connect to the elbow fitting 
a length of vent pipe sufficient to establish the draft, and orient the 
vent pipe to discharge vertically upward. Direct-vent oil-fired water 
heaters should be installed with venting equipment as specified in the 
manufacturer's instructions, using the minimum vertical and horizontal 
lengths of vent pipe recommended by the manufacturer.

                           5. Test Procedures

    5.1 Operational Mode Selection. For water heaters that allow for 
multiple user-selected operational modes, all procedures specified in 
this appendix shall be carried out with the water heater in the same 
operational mode (i.e., only one mode). This operational mode shall be 
the default mode (or similarly-

[[Page 381]]

named, suggested mode for normal operation) as defined by the 
manufacturer in its product literature for giving selection guidance to 
the consumer. For heat pump water heaters, if a default mode is not 
defined in the product literature, each test shall be conducted under an 
operational mode in which both the heat pump and any electric resistance 
backup heating element(s) are activated by the unit's control scheme, 
and which can achieve the internal storage tank temperature specified in 
this test procedure; if multiple operational modes meet these criteria, 
the water heater shall be tested under the most energy-intensive mode. 
If no default mode is specified and the unit does not offer an 
operational mode that utilizes both the heat pump and the electric 
resistance backup heating element(s), the first-hour rating test and the 
simulated-use test shall be tested in heat-pump-only mode. For other 
types of water heaters where a default mode is not specified, test the 
unit in all modes and rate the unit using the results of the most 
energy-intensive mode.
    5.2 Water Heater Preparation.
    5.2.1 Determination of Storage Tank Volume. For water heaters with a 
rated storage volume greater than or equal to 2 gallons, determine the 
storage capacity, Vst, of the water heater under test, in 
gallons (liters), by subtracting the tare weight--measured while the 
tank is empty--from the gross weight of the storage tank when completely 
filled with water (with all air eliminated and line pressure applied as 
described in section 2.5 of this appendix) and dividing the resulting 
net weight by the density of water at the measured temperature.
    5.2.2 Setting the Outlet Discharge Temperature.
    5.2.2.1 Flow-Activated Water Heaters, including certain 
instantaneous water heaters and certain storage-type water heaters. 
Initiate normal operation of the water heater at the full input rating 
for electric water heaters and at the maximum firing rate specified by 
the manufacturer for gas or oil water heaters. Monitor the discharge 
water temperature and set to a value of 125 [deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C) 
in accordance with the manufacturer's instructions. If the water heater 
is not capable of providing this discharge temperature when the flow 
rate is 1.7 gallons 0.25 gallons per minute (6.4 
liters 0.95 liters per minute), then adjust the 
flow rate as necessary to achieve the specified discharge water 
temperature. Once the proper temperature control setting is achieved, 
the setting must remain fixed for the duration of the maximum GPM test 
and the simulated-use test.
    5.2.2.2 Storage-Type Water Heaters that Are Not Flow-Activated.
    5.2.2.2.1 Tanks with a Single Temperature Controller.
    5.2.2.2.1.1 Water Heaters with Rated Volumes Less than 20 Gallons. 
Starting with a tank at the supply water temperature, initiate normal 
operation of the water heater. After cut-out, initiate a draw from the 
water heater at a flow rate of 1.0 gallon 0.25 
gallons per minute (3.8 liters 0.95 liters per 
minute) for 2 minutes. Starting 15 seconds after commencement of draw, 
record the outlet temperature at 15-second intervals until the end of 
the 2-minute period. Determine whether the maximum outlet temperature is 
within the range of 125 [deg]F 5 [deg]F (51.7 
[deg]C 2.8 [deg]C). If not, turn off the water 
heater, adjust the temperature controller, and then drain and refill the 
tank with supply water. Then, once again, initiate normal operation of 
the water heater, and repeat the 2-minute outlet temperature test 
following cut-out. Repeat this sequence until the maximum outlet 
temperature during the 2-minute test is within 125 [deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C). 
Once the proper temperature control setting is achieved, the setting 
must remain fixed for the duration of the first-hour rating test and the 
simulated-use test such that a second identical simulated-use test run 
immediately following the one specified in section 5.4 would result in 
average delivered water temperatures that are within the bounds 
specified in section 2.4 of this appendix.
    5.2.2.2.1.2 Water Heaters with Rated Volumes Greater than or Equal 
to 20 Gallons. Starting with a tank at the supply water temperature, 
initiate normal operation of the water heater. After cut-out, initiate a 
draw from the water heater at a flow rate of 1.7 gallons 0.25 gallons per minute (6.4 liters 0.95 liters per minute) for 5 minutes. Starting 15 
seconds after commencement of draw, record the outlet temperature at 15-
second intervals until the end of the 5-minute period. Determine whether 
the maximum outlet temperature is within the range of 125 [deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C). 
If not, turn off the water heater, adjust the temperature controller, 
and then drain and refill the tank with supply water. Then, once again, 
initiate normal operation of the water heater, and repeat the 5-minute 
outlet temperature test following cut-out. Repeat this sequence until 
the maximum outlet temperature during the 5-minute test is within of 125 
[deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C). Once the proper temperature control setting 
is achieved, the setting must remain fixed for the duration of the 
first-hour rating test and the simulated-use test such that a second 
identical simulated-use test run immediately following the one specified 
in section 5.4 would result in average delivered water temperatures that 
are within the bounds specified in section 2.4 of this appendix.
    5.2.2.2.2 Tanks with Two or More Temperature Controllers. Verify the 
temperature controller set-point while removing water in accordance with 
the procedure set forth for the first-hour rating test in section 5.3.3 
of this

[[Page 382]]

appendix. The following criteria must be met to ensure that all 
temperature controllers are set to deliver water at 125 [deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C):
    (a) At least 50 percent of the water drawn during the first draw of 
the first-hour rating test procedure shall be delivered at a temperature 
of 125 [deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C).
    (b) No water is delivered above 130 [deg]F (54.4 [deg]C) during 
first-hour rating test.
    (c) The delivery temperature measured 15 seconds after commencement 
of each draw begun prior to an elapsed time of 60 minutes from the start 
of the test shall be at 125 [deg]F 5 [deg]F (51.7 
[deg]C 2.8 [deg]C).
    If these conditions are not met, turn off the water heater, adjust 
the temperature controllers, and then drain and refill the tank with 
supply water. Repeat the procedure described at the start of section 
5.2.2.2.2 until the criteria for setting the temperature controllers is 
met.
    If the conditions stated above are met, the data obtained during the 
process of verifying the temperature control set-points may be used in 
determining the first-hour rating provided that all other conditions and 
methods required in sections 2 and 5.2.4 in preparing the water heater 
were followed.
    5.2.3 Power Input Determination. For all water heaters except 
electric types, initiate normal operation (as described in section 5.1) 
and determine the power input, P, to the main burners (including pilot 
light power, if any) after 15 minutes of operation. If the water heater 
is equipped with a gas appliance pressure regulator, the regulator 
outlet pressure shall be set within 10% of that 
recommended by the manufacturer. For oil-fired water heaters, the fuel 
pump pressure shall be within 10% of the 
manufacturer's specified pump pressure. Adjust all burners to achieve an 
hourly Btu (kJ) rating that is within 2% of the 
value specified by the manufacturer. For an oil-fired water heater, 
adjust the burner to give a CO2 reading recommended by the 
manufacturer and an hourly Btu (kJ) rating that is within 2% of that specified by the manufacturer. Smoke in the 
flue may not exceed No. 1 smoke as measured by the procedure in ASTM 
D2156 (incorporated by reference, see Sec. 430.3).
    5.2.4 Soak-In Period for Water Heaters with Rated Storage Volumes 
Greater than or Equal to 2 Gallons. For storage-type water heaters and 
instantaneous water heaters having greater than 2 gallons (7.6 liters) 
of storage (including heat pump water heaters having greater than 2 
gallons of storage), the water heater must sit filled with water and 
without any draws taking place for at least 12 hours after initially 
being energized so as to achieve the nominal temperature set-point 
within the tank and with the unit connected to a power source.
    5.3 Delivery Capacity Tests.
    5.3.1 General. For flow-activated water heaters, conduct the maximum 
GPM test, as described in section 5.3.2, Maximum GPM Rating Test for 
Flow-Activated Water Heaters, of this appendix. For all other water 
heaters, conduct the first-hour rating test as described in section 
5.3.3 of this appendix.
    5.3.2 Maximum GPM Rating Test for Flow-Activated Water Heaters. 
Establish normal water heater operation at the full input rate for 
electric water heaters and at the maximum firing rate for gas or oil 
water heaters with the discharge water temperature set in accordance 
with section 5.2.2.1 of this appendix.
    For this 10-minute test, either collect the withdrawn water for 
later measurement of the total mass removed or use a water meter to 
directly measure the water volume removed. Initiate water flow through 
the water heater and record the inlet and outlet water temperatures 
beginning 15 seconds after the start of the test and at subsequent 5-
second intervals throughout the duration of the test. At the end of 10 
minutes, turn off the water. Determine and record the mass of water 
collected, M10m, in pounds (kilograms), or the volume of 
water, V10m, in gallons (liters).
    5.3.3 First-Hour Rating Test.
    5.3.3.1 General. During hot water draws for water heaters with rated 
storage volumes greater than or equal to 20 gallons, remove water at a 
rate of 3.0 0.25 gallons per minute (11.4 0.95 liters per minute). During hot water draws for 
storage-type water heaters with rated storage volumes below 20 gallons, 
remove water at a rate of 1.0 0.25 gallon per 
minute (3.8 0.95 liters per minute). Collect the 
water in a container that is large enough to hold the volume removed 
during an individual draw and is suitable for weighing at the 
termination of each draw to determine the total volume of water 
withdrawn. As an alternative to collecting the water, a water meter may 
be used to directly measure the water volume(s) withdrawn.
    5.3.3.2 Draw Initiation Criteria. Begin the first-hour rating test 
by starting a draw on the storage-type water heater. After completion of 
this first draw, initiate successive draws based on the following 
criteria. For gas-fired and oil-fired water heaters, initiate successive 
draws when the temperature controller acts to reduce the supply of fuel 
to the main burner. For electric water heaters having a single element 
or multiple elements that all operate simultaneously, initiate 
successive draws when the temperature controller acts to reduce the 
electrical input supplied to the element(s). For electric water heaters 
having two or more elements that do not operate simultaneously, initiate 
successive draws when the applicable temperature controller acts to 
reduce the electrical input to the energized element located vertically 
highest in the storage tank. For

[[Page 383]]

heat pump water heaters that do not use supplemental, resistive heating, 
initiate successive draws immediately after the electrical input to the 
compressor is reduced by the action of the water heater's temperature 
controller. For heat pump water heaters that use supplemental resistive 
heating, initiate successive draws immediately after the electrical 
input to the first of either the compressor or the vertically highest 
resistive element is reduced by the action of the applicable water 
heater temperature controller. This draw initiation criterion for heat 
pump water heaters that use supplemental resistive heating, however, 
shall only apply when the water located above the thermostat at cut-out 
is heated to 125 [deg]F 5 [deg]F (51.7 [deg]C 
2.8 [deg]C). If this criterion is not met, then 
the next draw should be initiated once the heat pump compressor cuts 
out.
    5.3.3.3 Test Sequence. Establish normal water heater operation. If 
the water heater is not presently operating, initiate a draw. The draw 
may be terminated any time after cut-in occurs. After cut-out occurs 
(i.e., all temperature controllers are satisfied), record the internal 
storage tank temperature at each sensor described in section 4.5 of this 
appendix every one minute, and determine the mean tank temperature by 
averaging the values from these sensors.
    Initiate a draw after a maximum mean tank temperature (the maximum 
of the mean temperatures of the individual sensors) has been observed 
following a cut-out. Record the time when the draw is initiated and 
designate it as an elapsed time of zero ([tau]* = 0). (The superscript * 
is used to denote variables pertaining to the first-hour rating test). 
Record the outlet water temperature beginning 15 seconds after the draw 
is initiated and at 5-second intervals thereafter until the draw is 
terminated. Determine the maximum outlet temperature that occurs during 
this first draw and record it as T*max,1. For the duration of 
this first draw and all successive draws, in addition, monitor the inlet 
temperature to the water heater to ensure that the required 58 [deg]F 
2 [deg]F (14.4 [deg]C 1.1 
[deg]C) test condition is met. Terminate the hot water draw when the 
outlet temperature decreases to T*max,1 - 15 [deg]F 
(T*max,1 - 8.3 [deg]C). (Note, if the outlet temperature does 
not decrease to T*max,1 - 15 [deg]F (T*max,1 - 8.3 
[deg]C) during the draw, then hot water would be drawn continuously for 
the duration of the test. In this instance, the test would end when the 
temperature decreases to T*max,1- 15 [deg]F 
(T*max,1 - 8.3 [deg]C) after the electrical power and/or fuel 
supplied to the water heater is shut off, as described in the following 
paragraphs.) Record this temperature as T*min,1. Following 
draw termination, determine the average outlet water temperature and the 
mass or volume removed during this first draw and record them as 
T*del,i and M*1 or V*1, respectively.
    Initiate a second and, if applicable, successive draw(s) each time 
the applicable draw initiation criteria described in section 5.3.3.2 are 
satisfied. As required for the first draw, record the outlet water 
temperature 15 seconds after initiating each draw and at 5-second 
intervals thereafter until the draw is terminated. Determine the maximum 
outlet temperature that occurs during each draw and record it as 
T*max,i, where the subscript i refers to the draw number. 
Terminate each hot water draw when the outlet temperature decreases to 
T*max,i - 15 [deg]F (T*max,i - 8.3 [deg]C). Record 
this temperature as T*min,i. Calculate and record the average 
outlet temperature and the mass or volume removed during each draw 
(T*del,i and M*i or V*i, respectively). 
Continue this sequence of draw and recovery until one hour after the 
start of the test, then shut off the electrical power and/or fuel 
supplied to the water heater.
    If a draw is occurring at one hour from the start of the test, 
continue this draw until the outlet temperature decreases to 
T*max,n - 15 [deg]F (T*max,n - 8.3 [deg]C), at 
which time the draw shall be immediately terminated. (The subscript n 
shall be used to denote measurements associated with the final draw.) If 
a draw is not occurring one hour after the start of the test, initiate a 
final draw at one hour, regardless of whether the criteria described in 
section 5.3.3.2 of this appendix are satisfied. This draw shall proceed 
for a minimum of 30 seconds and shall terminate when the outlet 
temperature first indicates a value less than or equal to the cut-off 
temperature used for the previous draw (T*min,n-1). If an 
outlet temperature greater than T*min,n-1 is not measured 
within 30 seconds of initiation of the draw, zero additional credit 
shall be given towards first-hour rating (i.e., M*n = 0 or 
V*n = 0) based on the final draw. After the final draw is 
terminated, calculate and record the average outlet temperature and the 
mass or volume removed during the final draw (T*del,n and 
M*n or V*n, respectively).
    5.4 24-Hour Simulated Use Test.
    5.4.1 Selection of Draw Pattern. The water heater will be tested 
under a draw profile that depends upon the first-hour rating obtained 
following the test prescribed in section 5.3.3 of this appendix, or the 
maximum GPM rating obtained following the test prescribed in section 
5.3.2 of this appendix, whichever is applicable. For water heaters that 
have been tested according to the first-hour rating procedure, one of 
four different patterns shall be applied based on the measured first-
hour rating, as shown in Table I of this section. For water heater that 
have been tested according to the maximum GPM rating procedure, one of 
four different patterns shall be applied based on the maximum GPM, as 
shown in Table II of this section.

    The draw patterns are provided in Tables III.1 through III.4 in 
section 5.5 of this appendix. Use the appropriate draw pattern when 
conducting the test sequence provided in section 5.4.2 of this appendix 
for water heaters with rated storage volumes greater than or equal to 2 
gallons or section 5.4.3 of this appendix for water heaters with rated 
storage volumes less than 2 gallons.
    5.4.2 Test Sequence for Water Heaters with Rated Storage Volumes 
Greater Than or Equal to 2 Gallons. If the water heater is turned off, 
fill the water heater with supply water and maintain supply water 
pressure as described in section 2.6 of this appendix. Turn on the water 
heater and associated heat pump unit, if present. If turned on in this 
fashion, the soak-in period described in section 5.2.4 of this appendix 
shall be implemented. If the water heater has undergone a first-hour 
rating test prior to conduct of the simulated-use test, allow the water 
heater to fully recover after completion of that test such that the main 
burner, heating elements, or heat pump compressor of the water heater 
are no longer raising the temperature of the stored water. In all cases, 
the water heater shall sit idle for 1 hour prior to the start of the 24-
hour test; during which time no water is drawn from the unit and there 
is no energy input to the main heating elements, heat pump compressor, 
and/or burners. At the end of this period, the 24-hour simulated-use 
test will begin.
    At the start of the 24-hour test, record the mean tank temperature 
(T0), and the electrical and/or fuel measurement readings, as 
appropriate. Begin the 24-hour simulated use test by withdrawing the 
volume specified in the appropriate table in section 5.5 of this 
appendix (i.e., Table III.1, Table III.2, Table III.3, or Table III.4, 
depending on the first-hour rating or maximum GPM rating) for the first 
draw at the flow rate specified in the applicable table. Record the time 
when this first draw is initiated and assign it as the test elapsed time 
([tau]) of zero (0). Record the average storage tank and ambient 
temperature every minute throughout the 24-hour simulated-use test. At 
the elapsed times specified in the applicable draw pattern table in 
section 5.5 of this appendix for a particular draw pattern, initiate 
additional draws pursuant to the draw pattern, removing the volume of 
hot water at the prescribed flow rate specified by the table. The 
maximum allowable deviation from the specified volume of water removed 
for any single draw taken at a nominal flow rate of 1 GPM or 1.7 GPM is 
0.1 gallons (0.4 liters). 
The maximum allowable deviation from the specified volume of water 
removed for any single draw taken at a nominal flow rate of 3 GPM is 
0.25 gallons (0.9 liters). The quantity of water 
withdrawn during the last draw shall be increased or decreased as 
necessary such that the total volume of water withdrawn equals the 
prescribed daily amount for that draw pattern 1.0 
gallon (3.8 liters). If this adjustment to the 
volume drawn during the last draw results in no draw taking place, the 
test is considered invalid.
    All draws during the 24-hour simulated-use test shall be made at the 
flow rates specified in the applicable draw pattern table in section 5.5 
of this appendix, within a tolerance of 0.25 
gallons per minute (0. 9 liters per minute). 
Measurements of the inlet and outlet temperatures shall be made 5 
seconds after the draw is initiated and at every subsequent 3-second 
interval throughout the duration of each draw. Calculate and record the 
mean of the hot water discharge temperature and the cold water inlet 
temperature for each draw Tdel,i and Tin,i). 
Determine and record the net mass or volume removed (Mi or 
Vi), as appropriate, after each draw.
    At the end of the first recovery period following the first draw, 
which may extend beyond subsequent draws, record the maximum mean tank 
temperature observed after cut-out, Tmax,1, and the energy 
consumed by an

[[Page 385]]

electric resistance, gas, or oil-fired water heater (including 
electrical energy), from the beginning of the test, Qr. For 
heat pump water heaters, the total energy consumed during the first 
recovery by the heat pump (including compressor, fan, controls, pump, 
etc.) and, if applicable, by the resistive element(s) shall be recorded 
as Qr.
    The start of the portion of the test during which the standby loss 
coefficient is determined depends upon whether the unit has fully 
recovered from the first draw cluster. If a recovery is occurring at or 
within five minutes of the end of the final draw in the first draw 
cluster, as identified in the applicable draw pattern table in section 
5.5 of this appendix, then the standby period starts when a maximum 
average tank temperature is observed starting five minutes after the end 
of the recovery period that follows that draw. If a recovery does not 
occur at or within five minutes of the end of the final draw in the 
first draw cluster, as identified in the applicable draw pattern table 
in section 5.5 of this appendix, then the standby period starts five 
minutes after the end of that draw. Determine and record the total 
electrical energy and/or fossil fuel consumed from the beginning of the 
test to the start of the standby period, Qsu,0.
    In preparation for determining the energy consumed during standby, 
record the reading given on the electrical energy (watt-hour) meter, the 
gas meter, and/or the scale used to determine oil consumption, as 
appropriate. Record the mean tank temperature at the start of the 
standby period as Tsu,0. At 1-minute intervals, record the 
mean tank temperature and the electric and/or fuel instrument readings 
until the next draw is initiated. Just prior to initiation of the next 
draw, record the mean tank temperature as Tsu,f. If the water 
heater is undergoing recovery when the next draw is initiated, record 
the mean tank temperature Tsu,f at the minute prior to the 
start of the recovery. The time at which this value occurs is the end of 
the standby period. Determine the total electrical energy and/or fossil 
fuel energy consumption from the beginning of the test to this time and 
record as Qsu,f. Record the time interval between the start 
of the standby period and the end of the standby period as 
[tau]stby,1. Record the time during which water is not being 
withdrawn from the water heater during the entire 24-hour period as 
[tau]stby,2.
    In the event that the recovery period continues from the end of the 
last draw of the first draw cluster until the subsequent draw, the 
standby period will start after the end of the first recovery period 
after the last draw of the simulated-use test, when the temperature 
reaches the maximum average tank temperature, though no sooner than five 
minutes after the end of this recovery period. The standby period shall 
last eight hours, so testing will extend beyond the 24-hour duration of 
the simulated-use test. Determine and record the total electrical energy 
and/or fossil fuel consumed from the beginning of the simulated-use test 
to the start of the 8-hour standby period, Qsu,0. In 
preparation for determining the energy consumed during standby, record 
the reading(s) given on the electrical energy (watt-hour) meter, the gas 
meter, and/or the scale used to determine oil consumption, as 
appropriate. Record the mean tank temperature at the start of the 
standby period as Tsu,0. Record the mean tank temperature, 
the ambient temperature, and the electric and/or fuel instrument 
readings until the end of the 8 hour period. Record the mean tank 
temperature at the end of the 8 hour standby period as Tsu,f. 
If the water heater is undergoing recovery at the end of the standby 
period, record the mean tank temperature Tsu,f at the minute 
prior to the start of the recovery, which will mark the end of the 
standby period. Determine the total electrical energy and/or fossil fuel 
energy consumption from the beginning of the test to the end of the 
standby period and record this value as Qsu,f. Record the 
time interval between the start of the standby period and the end of the 
standby period as [tau]stby,1.
    Following the final draw of the prescribed draw pattern and 
subsequent recovery, allow the water heater to remain in the standby 
mode until exactly 24 hours have elapsed since the start of the 
simulated-use test (i.e., since [tau] = 0). During the last hour of the 
simulated-use test, power to the main burner, heating element, or 
compressor shall be disabled. At 24 hours, record the reading given by 
the gas meter, oil meter, and/or the electrical energy meter as 
appropriate. Determine the fossil fuel and/or electrical energy consumed 
during the entire 24-hour simulated-use test and designate the quantity 
as Q.
    5.4.3 Test Sequence for Water Heaters With Rated Storage Volume Less 
Than 2 Gallons.
    Establish normal operation with the discharge water temperature at 
125 [deg]F 5 [deg]F (51.7 [deg]C 2.8 [deg]C) and set the flow rate as determined in 
section 5.2 of this appendix. Prior to commencement of the 24-hour 
simulated-use test, the unit shall remain in an idle state in which 
controls are active but no water is drawn through the unit for a period 
of one hour. With no draw occurring, record the reading given by the gas 
meter and/or the electrical energy meter as appropriate. Begin the 24-
hour simulated-use test by withdrawing the volume specified in Tables 
III.1 through III.4 of section 5.5 of this appendix for the first draw 
at the flow rate specified. Record the time when this first draw is 
initiated and designate it as an elapsed time, [tau], of 0. At the 
elapsed times specified in Tables III.1 through III.4 for a particular 
draw pattern, initiate additional draws, removing

[[Page 386]]

the volume of hot water at the prescribed flow rate specified in Tables 
III.1 through III.4. The maximum allowable deviation from the specified 
volume of water removed for any single draw taken at a nominal flow rate 
less than or equal to 1.7 GPM (6.4 L/min) is 0.1 
gallons (0.4 liters). The maximum allowable 
deviation from the specified volume of water removed for any single draw 
taken at a nominal flow rate of 3 GPM (11.4 L/min) is 0.25 gallons (0.9 liters). The quantity of water drawn 
during the final draw shall be increased or decreased as necessary such 
that the total volume of water withdrawn equals the prescribed daily 
amount for that draw pattern 1.0 gallon (3.8 liters). If this adjustment to the volume drawn in 
the last draw results in no draw taking place, the test is considered 
invalid.
    Measurements of the inlet and outlet water temperatures shall be 
made 5 seconds after the draw is initiated and at every 3-second 
interval thereafter throughout the duration of the draw. Calculate the 
mean of the hot water discharge temperature and the cold water inlet 
temperature for each draw. Record the mass of the withdrawn water or the 
water meter reading, as appropriate, after each draw. At the end of the 
recovery period following the first draw, determine and record the 
fossil fuel and/or electrical energy consumed, Qr. Following 
the final draw and subsequent recovery, allow the water heater to remain 
in the standby mode until exactly 24 hours have elapsed since the start 
of the test (i.e., since [tau] = 0). At 24 hours, record the reading 
given by the gas meter, oil meter, and/or the electrical energy meter, 
as appropriate. Determine the fossil fuel and/or electrical energy 
consumed during the entire 24-hour simulated-use test and designate the 
quantity as Q.
    5.5 Draw Patterns. The draw patterns to be imposed during 24-hour 
simulated-use tests are provided in Tables III.1 through III.4. Subject 
each water heater under test to one of these draw patterns based on its 
first-hour rating or maximum GPM rating, as discussed in section 5.4.1 
of this appendix. Each draw pattern specifies the elapsed time in hours 
and minutes during the 24-hour test when a draw is to commence, the 
total volume of water in gallons (liters) that is to be removed during 
each draw, and the flow rate at which each draw is to be taken, in 
gallons (liters) per minute.

This difference (QHWD) must be added to the adjusted daily

          the 24-hour simulated-use test, Btu (kJ).
Qe = total electrical energy used during the 24-hour 
          simulated-use test, Btu (kJ).

    A modification is needed to take into account that the temperature 
difference between the outlet water temperature and supply water 
temperature may not be equivalent to the nominal value of 67 [deg]F (125 
[deg]F-58 [deg]F) or 37.3 [deg]C (51.7 [deg]C-14.4 [deg]C). The 
following equations adjust the experimental data to a nominal 67 [deg]F 
(37.3 [deg]C) temperature rise.
    The energy used to heat water may be computed as:
    [GRAPHIC] [TIFF OMITTED] TR11JY14.085
    
Where:

N = total number of draws in the draw pattern
Mi = the mass withdrawn for the ith draw(i = 1 to N), lb (kg)
Cpi = the specific heat of the water of the ith draw 
          evaluated at (Tdel,i + Tin,i)/2, Btu/(lb 
          [middot] [deg]F) (kJ/(kg [middot] [deg]C)).

    The energy required to heat the same quantity of water over a 67 
[deg]F (37.3 [deg]C) temperature rise is:

heating energy consumption value. Thus, the daily energy consumption 
value, which takes into account that the temperature rise across the 
water heater may not be 67 [deg]F (37.3 [deg]C), is:

          [deg]C + 14.4 [deg]C)/2 = 33.1 [deg]C), Btu/(lb [middot] 
          [deg]F) (kJ/(kg [middot] [deg]C)).

required by section 6.5 of ANSI/AHAM RAC-1 (incorporated by reference; 
see Sec. 430.3) and in accordance with ANSI/ASHRAE 16 (incorporated by 
reference; see Sec. 430.3).
    5.3 Standby mode and off mode annual energy consumption. Calculate 
the standby mode and off mode annual energy consumption for room air 
conditioners, ETSO, expressed in kilowatt-hours per year, 
according to the following:

ETSO = [(PIA x SIA) + (POFF 
x SOFF)] x K

Where:

PIA = room air conditioner inactive mode power, in watts, as 
          measured in section 4.2.1
POFF = room air conditioner off mode power, in watts, as 
          measured in section 4.2.2.
If the room air conditioner has both inactive mode and off mode, 
          SIA and SOFF both equal 5,115 / 2 = 
          2,557.5, where 5,115 is the total inactive and off mode annual 
          hours;
If the room air conditioner has an inactive mode but no off mode, the 
          inactive mode annual hours, SIA, is equal to 5,115 
          and the off mode annual hours, SOFF, is equal to 0;
If the room air conditioner has an off mode but no inactive mode, 
          SIA is equal to 0 and SOFF is equal to 
          STOT;
K = 0.001 kWh/Wh conversion factor for watt-hours to kilowatt-hours.

[[Page 403]]

test, with an error no greater than one percent. Alternatively, the test 
can be conducted using ``bottled'' natural gas of a higher heating value 
within 5 percent of 1,025 Btu's per standard cubic 
foot as long as the actual higher heating value of the bottled natural 
gas has been determined with an error no greater than one percent as 
certified by the supplier.
    1.4.3 Propane gas supply. For an unvented gas heater utilizing 
propane, maintain the gas supply to the heater with a normal inlet test 
pressure immediately ahead of all controls at 11 to 13 inches of water 
column. The regulator outlet pressure at normal supply test pressure 
shall be that recommended by the manufacturer. The propane supplied 
should have a higher heating value of within5 
percent of 2,500 Btu's per standard cubic foot. Determine the higher 
heating value in Btu's per standard foot, for the propane to be used in 
the test, with an error no greater than one percent. Alternatively, the 
test can be conducted using ``bottled'' propane of a higher heating 
value within 5 percent of 2,500 Btu's per standard 
cubic foot as long as the actual higher heating value of the bottled 
propane has been determined with an error no greater than one percent as 
certified by the supplier.
    1.4.4 Oil supply. For an unvented oil heater utilizing kerosene, 
determine the higher heating value in Btu's per gallon with an error no 
greater than one percent. Alternatively, the test can be conducted using 
a tested fuel of a higher heating value within 5

1.4.2, 1.4.3, or 1.4.4 of this appendix, as appropriate, determine the 
maximum fuel input (PF) of the heater under test in Btu's per 
hour. The energy flow instrumentation shall measure the maximum fuel 
input with an error no greater than one percent.
    2.3 Pilot light measurement. Except as provided in section 2.3.1 of 
this appendix, measure the energy input rate to the pilot light 
(Qp), with an error no greater than 3 percent, for unvented 
heaters so equipped.
    2.3.1 The measurement of Qp is not required for unvented 
heaters where the pilot light is designed to be turned off by the user 
when the heater is not in use (i.e., for units where turning the control 
to the OFF position will shut off the gas supply to the burner(s) and 
the pilot light). This provision applies only if an instruction to turn 
off the unit is provided on the heater near the gas control value (e.g., 
by label) by the manufacturer.
    2.4 Electrical standby mode power measurement. Except as provided in 
section 2.4.1 of this appendix, for all electric heaters and unvented 
heaters with electrical auxiliaries, measure the standby power 
(PW,SB) in accordance with the procedures in IEC 62301 Second 
Edition (incorporated by reference; see Sec. 430.3), with all 
electrical auxiliaries not activated. Voltage shall be as specified in 
section 1.4.1 Electrical supply of this appendix. The recorded standby 
power (PW,SB) shall be rounded to the second decimal place, 
and for loads greater than or equal to 10W, at least three significant 
figures shall be reported.
    2.4.1 The measurement of PW,SB is not required for 
heaters designed to be turned off by the user when the heater is not in 
use (i.e., for units where turning the control to the OFF position will 
shut off the electrical supply to the heater). This provision applies 
only if an instruction to turn off the unit is provided on the heater 
(e.g., by label) by the manufacturer.

                            3. Calculations.

    3.1 Annual energy consumption for primary electric heaters. For

    1.1 Adaptive control system means a clothes washer control system, 
other than an adaptive water fill control system, that is capable of 
automatically adjusting washer operation or washing conditions based on 
characteristics of the clothes load placed in the clothes container, 
without allowing or requiring user intervention or actions. The 
automatic adjustments may, for example, include automatic selection, 
modification, or control of any of the following: Wash water 
temperature, agitation or tumble cycle time, number of rinse cycles, or 
spin speed. The characteristics of the clothes load, which could trigger 
such adjustments, could, for example, consist of or be indicated by the 
presence of either soil, soap, suds, or any other additive laundering 
substitute or complementary product.
    1.2 Adaptive water fill control system means a clothes washer 
automatic water fill control system that is capable of automatically 
adjusting the water fill level based on the size or weight of the 
clothes load placed in the clothes container.

fill control system that does not allow or require the user to determine 
or select the water fill level, and includes adaptive water fill control 
systems and fixed water fill control systems.
    1.4 Bone-dry means a condition of a load of test cloth which has 
been dried in a dryer at maximum temperature for a minimum of 10

10 minute periods until the final weight change of the load is 1 percent 
or less.
    1.5 Clothes container means the compartment within the clothes 
washer that holds the clothes during the operation of the machine.
    1.6 Compact means a clothes washer which has a clothes container 
capacity of less than 1.6 ft\3\ (45 L).
    1.7 Deep rinse cycle means a rinse cycle in which the clothes 
container is filled with water to a selected level and the clothes load 
is rinsed by agitating it or tumbling it through the water.
    1.8 Energy test cycle for a basic model includes:
    (A) All wash/rinse temperature selections and water levels offered 
in the cycle recommended by the manufacturer for washing cotton or linen 
clothes, and
    (B) For each other wash/rinse temperature selection or water level 
available on that basic model, the portion(s) of other cycle(s) with 
that temperature selection or water level that, when tested pursuant to 
these test procedures, will contribute to an accurate representation of 
the energy consumption of the basic model as used by end users.
    If a warm rinse temperature selection is available on the clothes 
washer but is not available in the cycle recommended for washing cotton 
or linen clothes, the energy test cycle shall include the warm rinse 
temperature selection in the cycle most comparable to the cycle 
recommended for washing cotton or linen clothes.
    If an extra-hot temperature selection is available only on a 
sanitization cycle, the sanitization cycle should be included in the 
energy test cycle if the cycle is recommended by the manufacturer for 
washing clothing. If the extra-hot temperature selection is available 
only on a sanitization cycle not recommended by the manufacturer for 
washing clothing (e.g., a cycle intended only for sanitizing the wash 
drum), such a cycle is not required for consideration as part of the 
energy test cycle.
    (C) For clothes washers with electronic control systems, use the 
manufacturer default settings for any cycle selections, except for (1) 
the temperature selection, (2) the wash water fill levels, or (3) if 
necessary, the spin speeds on wash cycles used to determine remaining 
moisture content. Specifically, the manufacturer default settings must 
be used for wash conditions such as agitation/tumble operation, soil 
level, spin speed on wash cycles used to determine energy and water 
consumption, wash times, rinse times, optional rinse settings, water 
heating time for water-heating clothes washers, and all other wash 
parameters or optional features applicable to that wash cycle. Any 
optional wash cycle feature or setting (other than

[[Page 421]]

wash/rinse temperature, water fill level selection, or spin speed on 
wash cycles used to determine remaining moisture content) that is 
activated by default on the wash cycle under test must be included for 
testing unless the manufacturer instructions recommend not selecting 
this option, or recommend selecting a different option, for washing 
normally soiled cotton clothing.
    For clothes washers with control panels containing mechanical 
switches or dials, any optional settings, except for (1) the temperature 
selection, (2) the wash water fill levels, or (3) if necessary, the spin 
speeds on wash cycles used to determine remaining moisture content, must 
be in the position recommended by the manufacturer for washing normally 
soiled cotton clothing. If the manufacturer instructions do not 
recommend a particular switch or dial position to be used for washing 
normally soiled cotton clothing, the setting switch or dial must remain 
in its as-shipped position.
    (D) The determination of the energy test cycle must take into 
consideration all cycle settings available to the end user, including 
any cycle selections or cycle modifications provided by the manufacturer 
via software or firmware updates to the product, for the basic model 
under test.

fill control system that requires the user to determine or select the 
water fill level.
    1.13 Modified energy factor means the quotient of the cubic foot (or 
liter) capacity of the clothes container divided by the total clothes 
washer energy consumption per cycle, with such energy consumption 
expressed as the sum of the machine electrical energy consumption, the 
hot water energy consumption, and the energy required for removal of the 
remaining moisture in the wash load.
    1.14 Non-water-heating clothes washer means a clothes washer which 
does not have an internal water heating device to generate hot water.
    1.15 Spray rinse cycle means a rinse cycle in which water is sprayed 
onto the clothes for a period of time without maintaining any specific 
water level in the clothes container.
    1.16 Standard means a clothes washer which has a clothes container 
capacity of 1.6 ft\3\ (45 L) or greater.
    1.17 Temperature use factor means, for a particular wash/rinse 
temperature setting, the percentage of the total number of wash loads 
that an average user would wash with that setting.
    1.18 Thermostatically controlled water valves means clothes washer 
controls that have the ability to sense and adjust the hot and cold 
supply water.
    1.19 Warm wash means all wash temperature selections that are below

in a clothes washer in the following manner:
    2.6.3.1 Perform 5 complete normal wash-rinse-spin cycles, the first 
two with current AHAM Standard detergent Formula 3 and the last three 
without detergent. Place the test cloth in a clothes washer set at the 
maximum water level. Wash the load for ten minutes in soft water (17 ppm 
hardness or less) using 27.0 grams + 4.0 grams per pound of cloth load 
of AHAM Standard detergent Formula 3. The wash temperature is to be 
controlled to 135 [deg]F 5 [deg]F (57.2 [deg]C 
2.8 [deg]C) and the rinse temperature is to be 
controlled to 60 [deg]F 5 [deg]F (15.6 [deg]C 
2.8 [deg]C). Repeat the cycle with detergent and 
then repeat the cycle three additional times without detergent, bone 
drying the load between cycles (total of five wash and rinse cycles).
    2.6.4 Energy test cloth material. The energy test cloths and energy 
stuffer cloths shall be made from fabric meeting the following

    2.8.1 The test load sizes to be used to measure RMC are specified in 
section 3.8.1.
    2.8.2 Test loads for energy and water consumption measurements shall 
be bone dry prior to the first cycle of the test, and dried to a maximum 
of 104 percent of bone dry weight for subsequent testing.
    2.8.3 Prepare the energy test cloths for loading by grasping them in 
the center, lifting, and shaking them to hang loosely, as illustrated in 
Figure 2.8.3 of this appendix.
[GRAPHIC] [TIFF OMITTED] TR05AU15.000

    For all clothes washers, follow any manufacturer loading 
instructions provided to the user regarding the placement of clothing 
within the clothes container. In the absence of any manufacturer 
instructions regarding the placement of clothing within the clothes 
container, the following loading instructions apply.
    2.8.3.1 To load the energy test cloths in a top-loading clothes 
washer, arrange the cloths circumferentially around the axis of rotation 
of the clothes container, using alternating lengthwise orientations for 
adjacent pieces of cloth. Complete each cloth layer across its 
horizontal plane within the clothes container before adding a new layer. 
Figure 2.8.3.1 of this appendix illustrates the correct loading 
technique for a vertical-axis clothes washer.

[[Page 425]]

[GRAPHIC] [TIFF OMITTED] TR05AU15.001

    2.8.3.2 To load the energy test cloths in a front-loading clothes 
washer, grasp each test cloth in the center as indicated in section 
2.8.3 of this appendix, and then place each cloth into the clothes 
container prior to activating the clothes washer.
    2.9 Pre-conditioning.
    2.9.1 Nonwater-heating clothes washer. If the clothes washer has not 
been filled with water in the preceding 96 hours, pre-condition it by 
running it through a cold rinse cycle and then draining it to ensure 
that the hose, pump, and sump are filled with water.
    2.9.2 Water-heating clothes washer. If the clothes washer has not 
been filled with water in the preceding 96 hours, or if it has not been 
in the test room at the specified ambient conditions for 8 hours, pre-
condition it by running it through a cold rinse cycle and then draining 
it to ensure that the hose, pump, and sump are filled with water.
    2.10 Wash time setting. If one wash time is prescribed in the energy 
test cycle, that shall be the wash time setting; otherwise, the wash 
time setting shall be the higher of either the minimum or 70 percent of 
the maximum wash time available in the energy test cycle, regardless of 
the labeling of suggested dial locations. If 70% of the maximum wash 
time is not available on a dial with a discreet number of wash time 
settings, choose the next-highest setting greater than 70%. If the 
clothes washer is equipped with an electromechanical dial controlling 
wash time, reset the dial to the minimum wash time and then turn it in 
the direction of increasing wash time to reach the appropriate setting. 
If the appropriate setting is passed, return the dial to the minimum 
wash time and then turn in the direction of increasing wash time until 
the appropriate setting is reached.
    2.11 Test room temperature for water-heating clothes washers. 
Maintain the test room ambient air temperature at 75 [deg]F5 [deg]F (23.9 [deg]C2.8 [deg]C).

                          3. Test Measurements

    3.1 Clothes container capacity. Measure the entire volume which a 
dry clothes load could occupy within the clothes container during washer 
operation according to the following procedures:
    3.1.1 Place the clothes washer in such a position that the uppermost 
edge of the clothes container opening is leveled horizontally, so that 
the container will hold the maximum amount of water. For front-loading 
clothes washers, the door seal and shipping bolts or other forms of 
bracing hardware to support the wash drum during shipping must remain in 
place during the capacity measurement.
    If the design of a front-loading clothes washer does not include 
shipping bolts or other forms of bracing hardware to support the wash 
drum during shipping, a laboratory may support the wash drum by other 
means, including temporary bracing or support beams. Any temporary 
bracing or support beams must keep the wash drum in a fixed position, 
relative to the geometry of the door and door seal components, that is 
representative of the position of the wash drum

[[Page 426]]

during normal operation. The method used must avoid damage to the unit 
that would affect the results of the energy and water testing.
    For a front-loading clothes washer that does not include shipping 
bolts or other forms of bracing hardware to support the wash drum during 
shipping, the test report must document the alternative method used to 
support the wash drum during capacity measurement, and, pursuant to 
Sec. 429.71 of this chapter, the manufacturer must retain such 
documentation as part of its test records.
    3.1.2 Line the inside of the clothes container with a 2 mil 
thickness (0.051 mm) plastic bag. All clothes washer components that 
occupy space within the clothes container and that are recommended for 
use during a wash cycle must be in place and must be lined with a 2 mil 
thickness (0.051 mm) plastic bag to prevent water from entering any void 
space.
    3.1.3 Record the total weight of the machine before adding water.
    3.1.4 Fill the clothes container manually with either 60 [deg]F 
 5 [deg]F (15.6 [deg]C  2.8 
[deg]C) or 100 [deg]F  10 [deg]F (37.8 [deg]C 
 5.5 [deg]C) water to its uppermost edge. For a 
top-loading, vertical-axis clothes washer, the uppermost edge of the 
clothes container is defined as the highest point of the innermost 
diameter of the tub cover. Figure 3.1.4.1 illustrates the maximum fill 
level for top-loading vertical-axis clothes washers. Figure 3.1.4.2 
shows the location of the maximum fill level for a variety of example 
tub cover designs.

[[Page 427]]

[GRAPHIC] [TIFF OMITTED] TR05AU15.002

    For a front-loading horizontal-axis clothes washer, fill the clothes 
container to the highest point of contact between the door and the door 
gasket. If any portion of the door or gasket would occupy the measured 
volume space when the door is closed, exclude the volume that the door 
or gasket

[[Page 428]]

portion would occupy from the measurement. For a front-loading 
horizontal-axis clothes washer with a concave door shape, include any 
additional volume above the plane defined by the highest point of 
contact between the door and the door gasket, if that area can be 
occupied by clothing during washer operation. For a top-loading 
horizontal-axis clothes washer, include any additional volume above the 
plane of the door hinge that clothing could occupy during washer 
operation. Figure 3.1.4.3 illustrates the maximum fill volumes for all 
horizontal-axis clothes washer types.
[GRAPHIC] [TIFF OMITTED] TR05AU15.003

    For all clothes washers, exclude any volume that cannot be occupied 
by the clothing load during operation.
    3.1.5 Measure and record the weight of water, W, in pounds. 
Calculate the clothes container capacity as follows:

C = W/d

where:
C = Capacity in cubic feet (liters).

W = Mass of water in pounds (kilograms).
d = Density of water (62.0 lbs/ft\3\ for 100 [deg]F (993 kg/m\3\ for 
          37.8 [deg]C) or 62.3 lbs/ft\3\ for 60 [deg]F (998 kg/m\3\ for 
          15.6 [deg]C)).

    3.1.6 Calculate the clothes container capacity, C, to the nearest 
0.01 cubic foot for the purpose of determining test load sizes per Table 
5.1 of this appendix and for all subsequent calculations in this 
appendix that include the clothes container capacity.

    3.2 Procedure for measuring water and energy consumption values on 
all automatic and semi-automatic washers. All energy consumption tests 
shall be performed under the energy test cycle(s), unless otherwise 
specified. Table 3.2 indicates the sections below that govern tests of 
particular clothes washers, based on the number of wash/rinse 
temperature selections available on the model and also, in some 
instances, method of water heating. The procedures prescribed are 
applicable regardless of a clothes washer's washing capacity, loading 
port location, primary axis of rotation of the clothes container, and 
type of control system. Data from a wash cycle that provides a visual or 
audio indicator to alert the user that an out-of-balance condition has 
been detected, or that terminates prematurely if an out-of-balance 
condition is detected, and thus does not include the agitation/tumble 
operation, spin speed(s), wash times, and rinse times applicable to the 
wash cycle under test, shall be discarded. The test report must document 
the rejection of data from any wash cycle during testing and the reason 
for the rejection.
    3.2.1 Inlet water temperature and the wash/rinse temperature 
settings.
    3.2.1.1 For automatic clothes washers set the wash/rinse temperature 
selection control to obtain the wash water temperature desired (extra 
hot, hot, warm, or cold) and cold rinse, and open both the hot and cold 
water faucets.
    3.2.1.2 For semi-automatic washers: (1) For hot water temperature, 
open the hot water faucet completely and close the cold water faucet; 
(2) for warm inlet water temperature, open both hot and cold water 
faucets completely; (3) for cold water temperature, close the hot water 
faucet and open the cold water faucet completely.
    3.2.2 Total water consumption during the energy test cycle shall be 
measured, including hot and cold water consumption during wash, deep 
rinse, and spray rinse.
    3.2.3 Clothes washers with automatic water fill/manual water fill 
control systems
    3.2.3.1 Clothes washers with automatic water fill control system and 
alternate manual water fill control system. If a clothes washer with an 
automatic water fill control system allows user selection of manual 
controls as an alternative, then both manual and automatic

[[Page 429]]

modes shall be tested and, for each mode, the energy consumption 
(HET, MET, and DE) and water 
consumption (QT) values shall be calculated as set forth in 
section 4. Then the average of the two values (one from each mode, 
automatic and manual) for each variable shall be used in section 4 for 
the clothes washer.
    3.2.3.2 Clothes washers with automatic water fill control system.
    3.2.3.2.1. Not user adjustable. The maximum, minimum, and average 
water levels as defined in the following sections shall be interpreted 
to mean that amount of water fill which is selected by the control 
system when the respective test loads are used, as defined in Table 2.8. 
The load usage factors which shall be used when calculating energy 
consumption values are defined in Table 4.1.3.
    3.2.3.2.2 User-adjustable. Four tests shall be conducted on clothes 
washers with user-adjustable automatic water fill controls that affect 
the relative wash water levels. The first test shall be conducted using 
the maximum test load and with the automatic water fill control system 
set in the setting that will give the most energy intensive result. The 
second test shall be conducted with the minimum test load and with the 
automatic water fill control system set in the setting that will give 
the least energy intensive result. The third test shall be conducted 
with the average test load and with the automatic water fill control 
system set in the setting that will give the most energy intensive 
result for the given test load. The fourth test shall be conducted with 
the average test load and with the automatic water fill control system 
set in the setting that will give the least energy intensive result for 
the given test load. The energy and water consumption for the average 
test load and water level shall be the average of the third and fourth 
tests.
    3.2.3.3 Clothes washers with manual water fill control system. In 
accordance with Table 2.8, the water fill selector shall be set to the 
maximum water level available for the wash cycle under test for the 
maximum test load size and the minimum water level available for the 
wash cycle under test for the minimum test load size.

\1\ Only applicable to machines with warm rinse in any cycle.
\2\ This only applies to water heating clothes washers on which the maximum wash temperature available exceeds
  135 [deg]F (57.2 [deg]C).

    3.3 ``Extra-Hot Wash'' (Max Wash Temp 135 [deg]F (57.2 
[deg]C)) for water heating clothes washers only. Water and electrical 
energy consumption shall be measured for each water fill level and/or 
test load size as specified in 3.3.1 through 3.3.3 for the hottest wash 
setting available.
    Non-reversible temperature indicator labels, adhered to the inside 
of the clothes container, may be used to confirm that an extra-hot wash 
temperature greater than 135 [deg]F has been achieved during the wash 
cycle, under the following conditions. The label must remain waterproof, 
intact, and adhered to the wash drum throughout an entire wash cycle; 
provide consistent maximum temperature readings; and provide repeatable 
temperature indications sufficient to demonstrate that a wash 
temperature of greater than 135 [deg]F has been achieved. The label must 
have been verified to consistently indicate temperature measurements 
with an accuracy of 1 [deg]F if the label provides 
a temperature indicator at 135 [deg]F. If the label does not provide a 
temperature indicator at 135 [deg]F, the label must have been verified 
to consistently indicate temperature measurements with an accuracy of 
1 [deg]F if the next-highest temperature indicator 
is greater than 135 [deg]F and less than 140 [deg]F, or 3 [deg]F if the next-highest temperature indicator is 
140 [deg]F or greater. If the label does not provide a temperature 
indicator at 135 [deg]F, failure to activate the next-highest 
temperature indicator does not necessarily indicate the lack of an 
extra-hot wash temperature. However, such a result would not be 
considered a valid test due to the lack of verification of the water 
temperature requirement, in which case an alternative method must be 
used to confirm that an extra-hot wash temperature greater than 135 
[deg]F has been achieved during the wash cycle.
    If using a temperature indicator label to test a front-loading 
clothes washer, adhere the label along the interior surface of the

[[Page 430]]

clothes container drum, midway between the front and the back of the 
drum, adjacent to one of the baffles. If using a temperature indicator 
label to test a top-loading clothes washer, adhere the label along the 
interior surface of the clothes container drum, on the vertical portion 
of the sidewall, as close to the bottom of the container as possible.
    3.3.1 Maximum test load and water fill. Hot water consumption 
(Hmx), cold water consumption (Cmx), and 
electrical energy consumption (Emx) shall be measured for an 
extra hot wash/cold rinse energy test cycle, with the controls set for 
the maximum water fill level. The maximum test load size is to be used 
and shall be determined per Table 5.1.
    3.3.2 Minimum test load and water fill. Hot water consumption 
(Hmn), cold water consumption (Cmn), and 
electrical energy consumption (Emn) shall be measured for an 
extra hot wash/cold rinse energy test cycle, with the controls set for 
the minimum water fill level. The minimum test load size is to be used 
and shall be determined per Table 5.1.
    3.3.3 Average test load and water fill. For clothes washers with an 
automatic water fill control system, measure the values for hot water 
consumption (Hma), cold water consumption (Cma), 
and electrical energy consumption (Ema) for an extra-hot 
wash/cold rinse energy test cycle, with an average test load size as 
determined per Table 5.1.
    3.4 ``Hot Wash'' (Max Wash Temp<=135 [deg]F (57.2 [deg]C)). Water 
and electrical energy consumption shall be measured for each water fill 
level or test load size as specified in 3.4.1 through 3.4.3 for a 135 
[deg]F (57.2 [deg]C)) wash, if available, or for the hottest selection 
less than 135 [deg]F (57.2 [deg]C)).
    3.4.1 Maximum test load and water fill. Hot water consumption 
(Hhx), cold water consumption (Chx), and 
electrical energy consumption (Ehx) shall be measured for a 
hot wash/cold rinse energy test cycle, with the controls set for the 
maximum water fill level. The maximum test load size is to be used and 
shall be determined per Table 5.1.
    3.4.2 Minimum test load and water fill. Hot water consumption 
(Hhn), cold water consumption (Chn), and 
electrical energy consumption (Ehn) shall be measured for a 
hot wash/cold rinse energy test cycle, with the controls set for the 
minimum water fill level. The minimum test load size is to be used and 
shall be determined per Table 5.1.

determined for each water fill level and/or test load size as specified 
in 3.5.1 through 3.5.3 for the applicable warm water wash 
temperature(s). For a clothes washer with fewer than four discrete warm 
wash selections, test all warm wash temperature selections. For a 
clothes washer that offers four or more warm wash selections, test at 
all discrete selections, or test at the 25 percent, 50 percent, and 75 
percent positions of the temperature selection device between the 
hottest hot (<=135 [deg]F (57.2 [deg]C)) wash and the coldest cold wash. 
If a selection is not available at the 25, 50 or 75 percent position, in 
place of each such unavailable selection use the next warmer setting. 
Each reportable value to be used for the warm water wash setting shall 
be the arithmetic average of the results from all tests conducted 
pursuant to this section.
    3.5.1  Maximum test load and water fill. Hot water consumption 
(Hwx), cold water consumption (Cwx), and electrical energy consumption 
(Ewx) shall be measured with the controls set for the maximum water fill 
level. The maximum test load size is to be used and shall be determined 
per Table 5.1.
    3.5.2  Minimum test load and water fill. Hot water consumption

(Ewn) shall be measured with the controls set for the minimum water fill 
level. The minimum test load size is to be used and shall be determined 
per Table 5.1.

automatic water fill control system, measure the values for hot water 
consumption (Hwa), cold water consumption (Cwa), and electrical energy 
consumption (Ewa) with an average test load size as determined per Table 
5.1.
    3.6 ``Cold Wash'' (Minimum Wash Temperature Selection). Water and 
electrical energy consumption shall be measured for each water fill 
level or test load size as specified in sections 3.6.1 through 3.6.3 of 
this appendix for the coldest wash temperature selection available. For 
a clothes washer that offers two or more wash temperature settings 
labeled as cold, such as ``Cold'' and ``Tap Cold,'' the setting with the 
minimum wash temperature shall be considered the cold wash. If any of 
the other cold wash temperature settings add hot water to raise the wash 
temperature above the cold water supply temperature, as defined in 
section 2.3 of this appendix, those setting(s) shall be considered warm 
wash setting(s), as defined in section 1.20 of this appendix. If none of 
the cold wash temperature settings add hot water for any of the water 
fill levels or test load sizes required for the energy test cycle, the 
wash temperature setting labeled as ``Cold'' shall be considered the 
cold wash, and the other wash temperature setting(s) labeled as cold 
shall not be required for testing.

rinse energy test cycle, with an average test load size as determined 
per Table 5.1 of this appendix.
    3.7 Warm Rinse. Tests in sections 3.7.1 and 3.7.2 shall be conducted 
with the hottest rinse temperature available. If multiple wash 
temperatures are available with the hottest rinse temperature, any 
``warm wash'' temperature may be selected to conduct the tests.
    3.7.1 For the rinse only, measure the amount of hot water consumed 
by the clothes washer including all deep and spray rinses, for the 
maximum (RX), minimum (Rn), and, if required by

that are available in the energy test cycle, shall be tested at the 
maximum and minimum extremes of the available options, excluding any 
``no spin'' (zero spin speed) settings, in accordance with requirements 
in 3.8.2 or 3.8.3. The calculated RMCmax extraction and 
RMCmin extraction at the maximum and minimum settings, 
respectively, shall be combined as follows and the final RMC to be used 
in section 4.3 shall be:

RMC = 0.75 x RMCmax extraction + 0.25 x 
          RMCmin extraction
    3.8.5 The procedure for calculating RMC as defined in section 
3.8.2.5, 3.8.3.3., or 3.8.4 of this appendix may be replicated twice in

                      6. Waivers and Field Testing

    6.1 Waivers and Field Testing for Non-conventional Clothes Washers. 
Manufacturers of nonconventional clothes washers, such as clothes 
washers with adaptive control systems, must submit a petition for waiver 
pursuant to 10 CFR 430.27 to establish an acceptable test procedure for 
that clothes washer. For these and other clothes washers that have 
controls or systems such that the DOE test procedures yield results that 
are so unrepresentative of the clothes washer's true energy consumption 
characteristics as to provide materially inaccurate comparative data, 
field testing may be appropriate for establishing an acceptable test 
procedure. The following are guidelines for field testing which may be 
used by manufacturers in support of petitions for waiver. These 
guidelines are not mandatory and the Department may determine that they 
do not apply to a particular model. Depending upon a manufacturer's 
approach for conducting field testing, additional data may be required. 
Manufacturers are encouraged to communicate with the Department prior to 
the commencement of field tests which may be used to support a petition 
for waiver. Section 6.3 provides an example of field testing for a 
clothes washer with an adaptive water fill control system. Other 
features, such as the use of various spin speed selections, could be the 
subject of field tests.
    6.2 Nonconventional Wash System Energy Consumption Test. The field 
test may consist of a minimum of 10 of the nonconventional clothes 
washers (``test clothes washers'') and 10 clothes washers already being 
distributed in commerce (``base clothes washers''). The tests should 
include a minimum of 50 energy test cycles per clothes washer. The test 
clothes washers and base clothes washers should be identical in 
construction except for the controls or systems being tested. Equal 
numbers of both the test clothes washer and the base clothes washer 
should be tested simultaneously in comparable settings to minimize 
seasonal or consumer laundering conditions or variations. The clothes 
washers should be monitored in such a way as to accurately record the 
average total energy and water consumption per cycle, including water 
heating energy when electrically heated water is used, and the energy 
required to remove the remaining moisture of the test load. The field 
test results should be used to determine the best method to correlate 
the rating of the test clothes washer to the rating of the base clothes 
washer.
    6.3 Adaptive water fill control system field test. Section 3.2.3.1 
defines the test method for measuring energy consumption for clothes 
washers which incorporate control systems having both adaptive and 
alternate cycle selections. Energy consumption calculated by the method 
defined in section 3.2.3.1 assumes the adaptive cycle will be used 50 
percent of the time. This section can be used to develop field test data 
in support of a petition for waiver when it is believed that the 
adaptive cycle will be used more than 50 percent of the time. The field 
test sample size should be a minimum of 10 test clothes washers. The 
test clothes washers should be totally representative of the design, 
construction, and control system that will be placed in commerce. The 
duration of field testing in the user's house should be a minimum of 50 
energy test cycles, for each unit. No special instructions as to cycle 
selection or product usage should be given to the field test 
participants, other than inclusion of the product literature pack which 
would be shipped with all units, and instructions regarding filling out 
data collection forms, use of data collection equipment, or basic 
procedural methods. Prior to the test clothes washers being installed in 
the field test locations, baseline data should be developed for all 
field test units by conducting laboratory tests as defined by section 1 
through section 5 of these test procedures to determine the energy 
consumption, water consumption, and remaining moisture content values. 
The following data should be measured and recorded for each wash load 
during the test period: wash cycle selected, the mode of the clothes 
washer (adaptive or manual), clothes load dry weight (measured after the 
clothes washer and clothes dryer cycles are completed) in pounds, and 
type of articles in the clothes load (e.g., cottons, linens, permanent 
press). The wash loads used in calculating the in-home percentage split 
between adaptive and manual cycle usage should be only those wash loads 
which conform to the definition of the energy test cycle.
    Calculate:

T = The total number of energy test cycles run during the field test
Ta = The total number of adaptive control energy test cycles
Tm = The total number of manual control energy test cycles

    The percentage weighting factors:

Pa = (Ta/T) x 100 (the percentage weighting for 
adaptive control selection)
Pm = (Tm/T) x 100 (the percentage weighting for 
manual control selection)

    Energy consumption (HET, MET, and 
DE) and water consumption (QT), values calculated 
in section 4 for the manual and

[[Page 436]]

adaptive modes, should be combined using Pa and Pm 
as the weighting factors.

   Sec. Appendix J2 to Subpart B of Part 430--Uniform Test Method for 
Measuring the Energy Consumption of Automatic and Semi-automatic
Clothes Washers

    Note: Any representation related to the energy or water consumption 
of residential clothes washers must be based upon results generated 
using Appendix J2. Specifically, before February 1, 2016, 
representations must be based upon results generated either under this 
appendix or under Appendix J2 as it appeared in the 10 CFR parts 200-499 
edition revised as of January 1, 2015. Any representations made on or 
after February 1, 2016 must be made based upon results generated using 
this appendix.
    Before January 1, 2018, any representation related to the energy or 
water consumption of commercial clothes washers must be based on results 
generated using Appendix J1. Any representations made on or after 
January 1, 2018, must be based upon results generated using Appendix J2.

                       1. Definitions and Symbols

    1.1  Active mode means a mode in which the clothes washer is 
connected to a mains power source, has been activated, and is performing 
one or more of the main functions of washing, soaking, tumbling, 
agitating, rinsing, and/or removing water from the clothing, or is 
involved in functions necessary for these main functions, such as 
admitting water into the washer or pumping water out of the washer. 
Active mode also includes delay start and cycle finished modes.
    1.2  Active washing mode means a mode in which the clothes washer is 
performing any of the operations included in a complete cycle intended 
for washing a clothing load, including the main functions of washing, 
soaking, tumbling, agitating, rinsing, and/or removing water from the

    1.3  Adaptive control system means a clothes washer control system, 
other than an adaptive water fill control system, that is capable of 
automatically adjusting washer operation or washing conditions based on 
characteristics of the clothes load placed in the clothes container, 
without allowing or requiring user intervention or actions. The 
automatic adjustments may, for example, include automatic selection, 
modification, or control of any of the following: wash water 
temperature, agitation or tumble cycle time, number of rinse cycles, or 
spin speed. The characteristics of the clothes load, which could trigger 
such adjustments, could, for example, consist of or be indicated by the 
presence of either soil, soap, suds, or any other additive laundering 
substitute or complementary product.
    1.4  Adaptive water fill control system means a clothes washer 
automatic water fill control system that is capable of automatically 
adjusting the water fill level based on the size or weight of the 
clothes load placed in the clothes container.
    1.5  Automatic water fill control system means a clothes washer 
water fill control system that does not allow or require the user to 
determine or select the water fill level, and includes adaptive water 
fill control systems and fixed water fill control systems.
    1.6  Bone-dry means a condition of a load of test cloth that has 
been dried in a dryer at maximum temperature for a minimum of 10 
minutes, removed and weighed before cool down, and then dried again for 
10 minute periods until the final weight change of the load is 1 percent 
or less.
    1.7  Clothes container means the compartment within the clothes 
washer that holds the clothes during the operation of the machine.
    1.8  Cold rinse means the coldest rinse temperature available on the

container, the following loading instructions apply.
    2.9.2.1 To load the energy test cloths in a top-loading clothes 
washer, arrange the cloths circumferentially around the axis of rotation 
of the clothes container, using alternating lengthwise orientations for 
adjacent pieces of cloth. Complete each cloth layer across its 
horizontal plane within the clothes container before adding a new layer. 
Figure 2.9.2.1 of this appendix illustrates the correct loading 
technique for a vertical-axis clothes washer.

[[Page 441]]

[GRAPHIC] [TIFF OMITTED] TR05AU15.005

    2.9.2.2 To load the energy test cloths in a front-loading clothes 
washer, grasp each test cloth in the center as indicted in section 2.9.2 
of this appendix, and then place each cloth into the clothes container 
prior to activating the clothes washer.
    2.10 Clothes washer installation. Install the clothes washer in 
accordance with manufacturer's instructions. For combined low-power mode 
testing, install the clothes washer in accordance with Section 5, 
Paragraph 5.2 of IEC 62301 (incorporated by reference; see Sec. 430.3), 
disregarding the provisions regarding batteries and the determination, 
classification, and testing of relevant modes.
    2.11 Clothes washer pre-conditioning.
    2.11.1 Non-water-heating clothes washer. If the clothes washer has 
not been filled with water in the preceding 96 hours, pre-condition it 
by running it through a cold rinse cycle and then draining it to ensure 
that the hose, pump, and sump are filled with water.
    2.11.2 Water-heating clothes washer. If the clothes washer has not 
been filled with water in the preceding 96 hours, or if it has not been 
in the test room at the specified ambient conditions for 8 hours, pre-
condition it by running it through a cold rinse cycle and then draining 
it to ensure that the hose, pump, and sump are filled with water.
    2.12 Determining the energy test cycle. To determine the energy test 
cycle, evaluate the wash/rinse temperature selection flowcharts in the 
order in which they are presented in this section. The determination of 
the energy test cycle must take into consideration all cycle settings 
available to the end user, including any cycle selections or cycle 
modifications provided by the manufacturer via software or firmware 
updates to the product, for the basic model under test. The energy test 
cycle does not include any cycle that is recommended by the manufacturer 
exclusively for cleaning, deodorizing, or sanitizing the clothes washer.

                          3. Test Measurements

    3.1 Clothes container capacity. Measure the entire volume that a 
clothes load could occupy within the clothes container during active 
mode washer operation according to the following procedures:
    3.1.1 Place the clothes washer in such a position that the uppermost 
edge of the clothes container opening is leveled horizontally, so that 
the container will hold the

[[Page 447]]

maximum amount of water. For front-loading clothes washers, the door 
seal and shipping bolts or other forms of bracing hardware to support 
the wash drum during shipping must remain in place during the capacity 
measurement.
    If the design of a front-loading clothes washer does not include 
shipping bolts or other forms of bracing hardware to support the wash 
drum during shipping, a laboratory may support the wash drum by other 
means, including temporary bracing or support beams. Any temporary 
bracing or support beams must keep the wash drum in a fixed position, 
relative to the geometry of the door and door seal components, that is 
representative of the position of the wash drum during normal operation. 
The method used must avoid damage to the unit that would affect the 
results of the energy and water testing.
    For a front-loading clothes washer that does not include shipping 
bolts or other forms of bracing hardware to support the wash drum during 
shipping, the laboratory must fully document the alternative method used 
to support the wash drum during capacity measurement, include such 
documentation in the final test report, and pursuant to Sec. 429.71 of 
this chapter, the manufacturer must retain such documentation as part 
its test records.
    3.1.2 Line the inside of the clothes container with a 2 mil 
thickness (0.051 mm) plastic bag. All clothes washer components that 
occupy space within the clothes container and that are recommended for 
use during a wash cycle must be in place and must be lined with a 2 mil 
thickness (0.051 mm) plastic bag to prevent water from entering any void 
space.
    3.1.3 Record the total weight of the machine before adding water.
    3.1.4 Fill the clothes container manually with either 60 [deg]F 
 5 [deg]F (15.6 [deg]C  2.8 
[deg]C) or 100 [deg]F  10 [deg]F (37.8 [deg]C 
 5.5 [deg]C) water, with the door open. For a top-
loading vertical-axis clothes washer, fill the clothes container to the 
uppermost edge of the rotating portion, including any balance ring. 
Figure 3.1.4.1 of this appendix illustrates the maximum fill level for 
top-loading clothes washers.
[GRAPHIC] [TIFF OMITTED] TR05AU15.011

    For a front-loading horizontal-axis clothes washer, fill the clothes 
container to the highest point of contact between the door and the door 
gasket. If any portion of the door or gasket would occupy the measured 
volume space when the door is closed, exclude from the measurement the 
volume that the door or gasket portion would occupy. For a front-loading 
horizontal-axis clothes washer with a concave door shape, include any 
additional volume above the plane defined by the highest point of 
contact between the door and the door gasket, if that area can be 
occupied by clothing during washer operation. For a top-loading 
horizontal-axis clothes washer, include any additional volume above the 
plane of the door hinge that clothing could occupy during washer 
operation. Figure 3.1.4.2 of this appendix illustrates the maximum fill 
volumes for all horizontal-axis clothes washer types.

[[Page 448]]

[GRAPHIC] [TIFF OMITTED] TR05AU15.012

    For all clothes washers, exclude any volume that cannot be occupied 
by the clothing load during operation.
    3.1.5 Measure and record the weight of water, W, in pounds.
    3.1.6 Calculate the clothes container capacity as follows:

C = W/d

where:

C = Capacity in cubic feet (liters).
W = Mass of water in pounds (kilograms).
d = Density of water (62.0 lbs/ft\3\ for 100 [deg]F (993 kg/m\3\ for 
          37.8 [deg]C) or 62.3 lbs/ft\3\ for 60 [deg]F (998 kg/m\3\ for 
          15.6 [deg]C)).

    3.1.7 Calculate the clothes container capacity, C, to the nearest 
0.01 cubic foot for the purpose of determining test load sizes per Table 
5.1 of this appendix and for all subsequent calculations that include 
the clothes container capacity.
    3.2 Procedure for measuring water and energy consumption values on 
all automatic and semi-automatic washers.
    3.2.1 Perform all energy consumption tests under the energy test 
cycle.
    3.2.2 Perform the test sections listed in Table 3.2.2 in accordance 
with the wash/rinse temperature selections available in the energy test

water faucets.
    3.2.3.2 For semi-automatic washers:
    (1) For hot inlet water temperature, open the hot water faucet 
completely and close the cold water faucet;
    (2) For warm inlet water temperature, open both hot and cold water 
faucets completely;
    (3) For cold inlet water temperature, close the hot water faucet and 
open the cold water faucet completely.
    3.2.4 Wash/rinse temperature selection. Set the wash/rinse 
temperature selection control to obtain the desired wash/rinse 
temperature selection within the energy test cycle.
    3.2.5 Wash time setting. If one wash time is prescribed for the wash 
cycle under test, that shall be the wash time setting; otherwise, the 
wash time setting shall be the higher of either the minimum or 70 
percent of the maximum wash time available for the wash cycle under 
test, regardless of the labeling of suggested dial locations. If 70% of 
the maximum wash time is not available on a dial with a discreet number 
of wash time settings, choose the next-highest setting greater than 70%. 
If the clothes washer is equipped with an electromechanical dial 
controlling wash time, reset the dial to the minimum wash time and then 
turn it in the direction of increasing wash time to reach the 
appropriate setting. If the appropriate setting is passed, return the 
dial to the minimum wash time and then turn in the direction of 
increasing wash time until the appropriate setting is reached.
    3.2.6 Water fill levels.
    3.2.6.1 Clothes washers with manual water fill control system. Set 
the water fill selector to the maximum water level available for the 
wash cycle under test for the maximum test load size and the minimum 
water level available for the wash cycle under test for the minimum test 
load size.
    3.2.6.2 Clothes washers with automatic water fill control system.

[[Page 449]]

    3.2.6.2.1 Not user adjustable. The maximum, minimum, and average 
water levels as described in the following sections refer to the amount 
of water fill that is automatically selected by the control system when 
the respective test loads are used.
    3.2.6.2.2 User adjustable. Conduct four tests on clothes washers 
with user adjustable automatic water fill controls that affect the 
relative wash water levels. Conduct the first test using the maximum 
test load and with the automatic water fill control system set in the 
setting that will give the most energy intensive result. Conduct the 
second test using the minimum test load and with the automatic water 
fill control system set in the setting that will give the least energy 
intensive result. Conduct the third test using the average test load and 
with the automatic water fill control system set in the setting that 
will give the most energy intensive result for the given test load. 
Conduct the fourth test using the average test load and with the 
automatic water fill control system set in the setting that will give 
the least energy intensive result for the given test load. Average the 
results of the third and fourth tests to obtain the energy and water 
consumption values for the average test load size.
    3.2.6.3 Clothes washers with automatic water fill control system and 
alternate manual water fill control system. If a clothes washer with an 
automatic water fill control system allows user selection of manual 
controls as an alternative, test both manual and automatic modes and, 
for each mode, calculate the energy consumption (HET, 
MET, and DE) and water consumption (QT) 
values as set forth in section 4 of this appendix. Then, calculate the 
average of the two values (one from each mode, automatic and manual) for 
each variable (HET, MET, DE, and 
QT) and use the average value for each variable in the final 
calculations in section 4 of this appendix.
    3.2.7 Manufacturer default settings. For clothes washers with 
electronic control systems, use the manufacturer default settings for 
any cycle selections, except for (1) the temperature selection, (2) the 
wash water fill levels, or (3) if necessary, the spin speeds on wash 
cycles used to determine remaining moisture content. Specifically, the 
manufacturer default settings must be used for wash conditions such as 
agitation/tumble operation, soil level, spin speed on wash cycles used 
to determine energy and water consumption, wash times, rinse times, 
optional rinse settings, water heating time for water heating clothes 
washers, and all other wash parameters or optional features applicable 
to that wash cycle. Any optional wash cycle feature or setting (other 
than wash/rinse temperature, water fill level selection, or spin speed 
on wash cycles used to determine remaining moisture content) that is 
activated by default on the wash cycle under test must be included for 
testing unless the manufacturer instructions recommend not selecting 
this option, or recommend selecting a different option, for washing 
normally soiled cotton clothing.
    For clothes washers with control panels containing mechanical 
switches or dials, any optional settings, except for (1) the temperature 
selection, (2) the wash water fill levels, or (3) if necessary, the spin 
speeds on wash cycles used to determine remaining moisture content, must 
be in the position recommended by the manufacturer for washing normally 
soiled cotton clothing. If the manufacturer instructions do not 
recommend a particular switch or dial position to be used for washing 
normally soiled cotton clothing, the setting switch or dial must remain 
in its as-shipped position.
    3.2.8 For each wash cycle tested, include the entire active washing 
mode and exclude any delay start or cycle finished modes.
    3.2.9 Discard the data from a wash cycle that provides a visual or 
audio indicator to alert the user that an out-of-balance condition has 
been detected, or that terminates prematurely if an out-of-balance 
condition is detected, and thus does not include the agitation/tumble 
operation, spin speed(s), wash times, and rinse times applicable to the 
wash cycle under test. Document in the test report the rejection of data 
from any wash cycle during testing and the reason for the rejection.
    3.3 Extra-Hot Wash/Cold Rinse. Measure the water and electrical 
energy consumption for each water fill level and test load size as 
specified in sections 3.3.1 through 3.3.3 of this appendix for the 
Extra-Hot Wash/Cold Rinse as defined within the energy test cycle.
    Non-reversible temperature indicator labels, adhered to the inside 
of the clothes container, may be used to confirm that an extra-hot wash 
temperature greater than 135 [deg]F has been achieved during the wash 
cycle, under the following conditions. The label must remain waterproof, 
intact, and adhered to the wash drum throughout an entire wash cycle; 
provide consistent maximum temperature readings; and provide repeatable 
temperature indications sufficient to demonstrate that a wash 
temperature of greater than 135 [deg]F has been achieved. The label must 
have been verified to consistently indicate temperature measurements 
with an accuracy of 1 [deg]F if the label provides 
a temperature indicator at 135 [deg]F. If the label does not provide a 
temperature indicator at 135 [deg]F, the label must have been verified 
to consistently indicate temperature measurements with an accuracy of 
1 [deg]F if the next-highest temperature indicator 
is greater than 135 [deg]F and less than 140 [deg]F, or 3 [deg]F if the next-highest temperature indicator is 
140 [deg]F or greater. If the label does not provide a temperature 
indicator at 135 [deg]F, failure to

[[Page 450]]

activate the next-highest temperature indicator does not necessarily 
indicate the lack of an extra-hot wash temperature. However, such a 
result would not be considered a valid test due to the lack of 
verification of the water temperature requirement, in which case an 
alternative method must be used to confirm that an extra-hot wash 
temperature greater than 135 [deg]F has been achieved during the wash 
cycle.
    If using a temperature indicator label to test a front-loading 
clothes washer, adhere the label along the interior surface of the 
clothes container drum, midway between the front and the back of the 
drum, adjacent to one of the baffles. If using a temperature indicator 
label to test a top-loading clothes washer, adhere the label along the 
interior surface of the clothes container drum, on the vertical portion 
of the sidewall, as close to the bottom of the container as possible.

percent position, in place of each such unavailable selection, use the 
next warmer setting. For each reportable value to be used for the Warm 
Wash/Cold Rinse temperature selection, calculate the average of all Warm 
Wash/Cold Rinse temperature selections tested pursuant to this section.

performed, use the average of the three corrected RMC measurements as 
the final corrected RMC in section 4.3 of this appendix.
    3.9 Combined low-power mode power. Connect the clothes washer to a 
watt meter as specified in section 2.5.3 of this appendix. Establish the 
testing conditions set forth in sections 2.1, 2.4, and 2.10 of this 
appendix.
    3.9.1 Perform combined low-power mode testing after completion of an 
active mode wash cycle included as part of the energy test cycle; after 
removing the test load; without changing the control panel settings used 
for the active mode wash cycle; with the door closed; and without 
disconnecting the electrical energy supply to the clothes washer between 
completion of the active mode wash cycle and the start of combined low-
power mode testing.
    3.9.2 For a clothes washer that takes some time to automatically 
enter a stable inactive mode or off mode state from a higher power state 
as discussed in Section 5, Paragraph 5.1, note 1 of IEC 62301 
(incorporated by reference; see Sec. 430.3), allow sufficient time for 
the clothes washer to automatically reach the default inactive/off mode 
state before proceeding with the test measurement.
    3.9.3 Once the stable inactive/off mode state has been reached, 
measure and record the default inactive/off mode power, 
Pdefault, in watts, following the test procedure for the 
sampling method specified in Section 5, Paragraph 5.3.2 of IEC 62301.
    3.9.4 For a clothes washer with a switch, dial, or button that can 
be optionally selected by the end user to achieve a lower-power 
inactive/off mode state than the default inactive/off mode state 
measured in section 3.9.3 of this appendix, after performing the 
measurement in section 3.9.3, activate the switch, dial, or button to 
the position resulting in the lowest power consumption and repeat the 
measurement procedure described in section 3.9.3. Measure and record the 
lowest-power inactive/off mode power, Plowest, in Watts.
    3.10 Energy consumption for the purpose of determining the cycle 
selection(s) to be included in the energy test cycle. This section is 
implemented only in cases where the energy test cycle flowcharts in 
section 2.12 require the determination of the wash/rinse temperature 
selection with the highest energy consumption.
    3.10.1 For the wash/rinse temperature selection being considered 
under this section, establish the testing conditions set forth in

[[Page 453]]

wash/rinse temperature selection. For all wash/rinse temperature 
selections, the manufacturer default settings shall be used as described 
in section 3.2.7 of this appendix.
    3.10.2 Use the clothes washer's maximum test load size, determined 
from Table 5.1 of this appendix, for testing under this section.

adjustable automatic water fill control system, or automatic water fill 
control system with alternate manual water fill control system, use the 
water fill selector setting resulting in the maximum water level 
available for each cycle selection for testing under this section.
    3.10.4 Each wash cycle tested under this section shall include the 
entire active washing mode and exclude any delay start or cycle finished 
modes.
    3.10.5 Measure each wash cycle's electrical energy consumption 
(EX) and hot water consumption (HX). Calculate the 
total energy consumption for each cycle selection (ETX), as 
follows:

ETX = EX + (HX x T x K)

where:

EX is the electrical energy consumption, expressed in 
          kilowatt-hours per cycle.
HX is the hot water consumption, expressed in gallons per 
          cycle.
T = nominal temperature rise = 75 [deg]F (41.7 [deg]C).
K = Water specific heat in kilowatt-hours per gallon per degree F = 
          0.00240 kWh/gal - [deg]F (0.00114 kWh/L- [deg]C).

                      6. Waivers and Field Testing

    6.1 Waivers and Field Testing for Nonconventional Clothes Washers. 
Manufacturers of nonconventional clothes washers, such as clothes 
washers with adaptive control systems, must submit a petition for waiver 
pursuant to 10 CFR 430.27 to establish an acceptable test procedure for 
that clothes washer if the washer cannot be tested pursuant to the DOE 
test procedure or the DOE test procedure yields results that are so 
unrepresentative of the clothes washer's true energy consumption 
characteristics as to provide materially inaccurate comparative data. In 
such cases, field testing may be appropriate for establishing an 
acceptable test procedure. The following are guidelines for field 
testing that may be used by manufacturers in support of petitions for 
waiver. These guidelines are not mandatory and the Department may 
determine that they do not apply to a particular model. Depending upon a 
manufacturer's approach for conducting field testing, additional data 
may be required. Manufacturers are encouraged to communicate with the 
Department prior to the commencement of field tests that may be used to 
support a petition for waiver. Section 6.3 of this appendix provides an 
example of field testing for a clothes washer with an adaptive water 
fill control system. Other features, such as the use of various spin 
speed selections, could be the subject of field tests.
    6.2 Nonconventional Wash System Energy Consumption Test. The field 
test may consist of a minimum of 10 of the nonconventional clothes 
washers (``test clothes washers'') and 10 clothes washers already being 
distributed in commerce (``base clothes washers''). The tests should 
include a minimum of 50 wash cycles per clothes washer. The test clothes 
washers and base clothes washers should be identical in construction 
except for the controls or systems being tested. Equal numbers of both 
the test clothes washer and the base clothes washer should be tested 
simultaneously in comparable settings to minimize seasonal or end-user 
laundering conditions or variations. The clothes washers should be 
monitored in such a way as to accurately record the average total energy 
and water consumption per cycle, including water heating energy when 
electrically heated water is used, and the energy required to remove the 
remaining moisture of the test load. Standby and off mode energy 
consumption should be measured according to section 4.4 of this test 
procedure. The field test results should be used to determine the best 
method to correlate the rating of the test clothes washer to the rating 
of the base clothes washer.
    6.3 Adaptive water fill control system field test. (1) Section 
3.2.6.3 of this appendix defines the test method for measuring energy 
consumption for clothes washers that incorporate both adaptive 
(automatic) and alternate manual water fill control systems. Energy 
consumption calculated by the method defined in section 3.2.6.3 of this 
appendix assumes the adaptive cycle will be used 50 percent of the time. 
This section can be used to develop field test data in support of a 
petition for waiver when it is believed that the adaptive cycle will be 
used more than 50 percent of the time. The field test sample size should 
be a minimum of 10 test clothes washers. The test clothes washers should 
be representative of the design, construction, and control system that 
will be placed in commerce. The duration of field testing in the user's 
house should be a minimum of 50 wash cycles, for each unit. No special 
instructions as to cycle selection or product usage should be given to 
the field test participants, other than inclusion of the product 
literature pack that would be shipped with all units, and instructions 
regarding filling out data collection forms, use of data collection 
equipment, or basic procedural methods. Prior to the test clothes 
washers being installed in the field test locations, baseline data 
should be

[[Page 459]]

developed for all field test units by conducting laboratory tests as 
defined by section 1 through section 5 of this appendix to determine the 
energy consumption, water consumption, and remaining moisture content 
values. The following data should be measured and recorded for each wash 
load during the test period: wash cycle selected, the mode of the 
clothes washer (adaptive or manual), clothes load dry weight (measured 
after the clothes washer and clothes dryer cycles are completed) in 
pounds, and type of articles in the clothes load (e.g., cottons, linens, 
permanent press). The wash cycles used in calculating the in-home 
percentage split between adaptive and manual cycle usage should be only 
those wash cycles that conform to the definition of the energy test 
cycle.
    Calculate:

T = The total number of wash cycles run during the field test.
Ta = The total number of adaptive control wash cycles.
Tm = The total number of manual control wash cycles.

    The percentage weighting factors:

Pa = (Ta/T) x 100% (the percentage weighting for 
          adaptive control selection)
Pm = (Tm/T) x 100% (the percentage weighting for 
          manual control selection)

    (2) Energy consumption (HET, MET, and 
DE) and water consumption (QT) values calculated 
in section 4 of this appendix for the manual and adaptive modes should 
be combined using Pa and Pm as the weighting 
factors.

   Sec. Appendix J3 to Subpart B of Part 430--Uniform Test Method for 
 Measuring the Moisture Absorption and Retention Characteristics
 of New  Energy Test Cloth Lots

    Note: DOE maintains an historical record of the standard extractor 
test data and final correction curve coefficients for each approved lot 
of energy test cloth. These can be accessed through DOE's Web page for 
standards and test procedures for residential clothes washers at DOE's 
Building Technologies Office Appliance and Equipment Standards Web site.

                              1. Objective

    The following procedure is used to evaluate the moisture absorption 
and retention characteristics of a new lot of test cloth by measuring 
the remaining moisture content (RMC) in a standard extractor at a 
specified set of conditions. The results are used to develop a set of 
coefficients that correlate the measured RMC values of the new test 
cloth lot with a set of standard RMC values established as an historical 
reference point. These correction coefficients are applied to the RMC 
measurements performed during testing according to appendix J1 or 
appendix J2 to 10 CFR part 430 subpart B, ensuring that the final 
corrected RMC measurement for a clothes washer remains independent of 
the test cloth lot used for testing.

                             2. Definitions

    2.1 AHAM means the Association of Home Appliance Manufacturers.
    2.2 Bone-dry means a condition of a load of test cloth that has been 
dried in a dryer at maximum temperature for a minimum of 10 minutes, 
removed and weighed before cool down, and then dried again for 10 minute 
periods until the final weight change of the load is 1 percent or less.
    2.3 Lot means a quantity of cloth that has been manufactured with 
the same batches of cotton and polyester during one continuous process.

                          3. Testing Conditions

    3.1 Table 3.1 of this appendix provides the matrix of test 
conditions. In the table, ``g Force'' represents units of gravitational 
acceleration. When this matrix is repeated 3 times, a total of 60 
extractor RMC test runs are required. For the purpose of the extractor 
RMC test, the test cloths may be used for up to 60 test runs (after 
preconditioning as specified in appendix J1 or appendix J2).

    3.2 Perform the standard extractor RMC tests using a North Star 
Engineered Products Inc. (formerly Bock) Model 215 extractor (having a 
basket diameter of 20 inches, height of 11.5 inches, and volume of 2.09 
ft\3\), with a variable speed drive (North Star Engineered Products, 
P.O. Box 5127, Toledo, OH 43611) or an equivalent extractor with same 
basket design (i.e., diameter, height, volume, and hole configuration) 
and variable speed drive. Table 3.2 shows the extractor spin speed, in 
revolutions per minute (RPM), that must be used to attain each required 
g-force level.

------------------------------------------------------------------------
100........................................................   594  5 [deg]F (57.2 [deg]C 
 2.8 [deg]C) and the rinse temperature is to be 
controlled to 60 [deg]F  5; [deg]F (15.6 [deg]C 
 2.8 [deg]C). Repeat the cycle with detergent and 
then repeat the cycle three additional times without detergent, bone 
drying the load between cycles (for a total of five complete wash-rinse-
spin cycles).
    4.2  Test load composition. Test loads must be comprised of randomly 
selected cloth at the beginning, middle and end of a lot.
    4.3  Test load size. Use a test load size of 8.4 lbs. Two test loads 
may be used for standard extractor RMC tests, with each load used for 
half of the total number of required tests.

                          5. Test Measurements

    5.1 Dry the test cloth until it is ``bone-dry'' according to the 
definition in section 2.2 of this appendix. Record the bone-dry weight 
of the test load (WI).
    5.2 Prepare the test load for soak by grouping four test cloths into 
loose bundles. Create the bundles by hanging four cloths vertically from 
one corner and loosely wrapping the test cloth onto itself to form the 
bundle. Bundles should be wrapped loosely to ensure consistency of water 
extraction. Then place the bundles into the water to soak. Eight to nine 
bundles will be formed depending on the test load. The ninth bundle may 
not equal four cloths but can incorporate energy stuffer cloths to help 
offset the size difference.
    5.3 Soak the test load for 20 minutes in 10 gallons of soft (<17 
ppm) water. The entire test load must be submerged. Maintain a water 
temperature of 100 [deg]F  5 [deg]F (37.8 [deg]C 
 2.8 [deg]C) at all times between the start and 
end of the soak.
    5.4 Remove the test load and allow each of the test cloth bundles to 
drain over the water bath for a maximum of 5 seconds.
    5.5 Manually place the test cloth bundles in the basket of the 
extractor, distributing them evenly by eye. The draining and loading 
process must take no longer than 1 minute. Spin the load at a fixed 
speed corresponding to the intended centripetal acceleration level 
(measured in units of the acceleration of gravity, g)  1g for the intended time period  
5 seconds. Begin the timer when the extractor meets the required spin 
speed for each test.
    5.6 Record the weight of the test load immediately after the 
completion of the extractor spin cycle (WC).
    5.7 Calculate the remaining moisture content of the test load as 
(WC-WI)/WI.
    5.8 Draining the soak tub is not necessary if the water bath is 
corrected for water level and temperature before the next extraction.
    5.9 Drying the test load in between extraction runs is not 
necessary. However, the bone dry weight must be checked after every 12 
extraction runs to make sure the bone dry weight is within tolerance 
(8.4  0.1 lb).
    5.10 The test load must be soaked and extracted once following bone 
drying, before continuing with the remaining extraction

[[Page 461]]

runs. Perform this extraction at the same spin speed used for the 
extraction run prior to bone drying, for a time period of 4 minutes. 
Either warm or cold soak temperature may be used.
    5.11 Measure the remaining moisture content of the test load at five 
g levels: 100 g, 200 g, 350 g, 500 g, and 650 g, using two different 
spin times at each g level: 4 minutes and 15 minutes.
    5.12 Repeat sections 5.1 through 5.11 of this appendix using soft 
(<17 ppm) water at 60 [deg]F5 [deg]F (15.6 [deg]C 
 2.8 [deg]C).

                 6. Calculation of RMC Correction Curve

    6.1 Average the values of 3 test runs, and fill in Table 3.1 of this 
appendix. Perform a linear least-squares fit to determine coefficients A 
and B such that the standard RMC values shown in Table 6.1 of this 
appendix (RMCstandard) are linearly related to the RMC values 
measured in section 5 of this appendix (RMCcloth):

RMCstandard  A * RMCcloth + B

where A and B are coefficients of the linear least-squares fit.

    6.2 Perform an analysis of variance with replication test using two 
factors, spin speed and lot, to check the interaction of speed and lot. 
Use the values from Table 3.1 and Table 6.1 of this appendix in the 
calculation. The ``P'' value of the F-statistic for interaction between 
spin speed and lot in the variance analysis must be greater than or 
equal to 0.1. If the ``P'' value is less than 0.1, the test cloth is 
unacceptable. ``P'' is a theoretically based measure of interaction 
based on an analysis of variance.

               7. Application of the RMC Correction Curve

    7.1 Using the coefficients A and B calculated in section 6.1 of this 
appendix:

RMCcorr = A x RMC + B

    7.2 Apply this RMC correction curve to measured RMC values in 
appendix J1 and appendix J2.

                                1.1 Scope

    This test procedure provides a method of determining SEER, EER, HSPF 
and PW,OFF for central air conditioners and central air 
conditioning heat pumps including the following categories:
(a) Split-system air conditioners, including single-split, multi-head 
mini-split, multi-split (including VRF), and multi-circuit systems

    For purposes of this appendix, the Department of Energy incorporates 
by reference specific sections of several industry standards, as listed 
in Sec. 430.3. In cases where there is a conflict, the language of the 
test procedure in this appendix takes precedence over the incorporated 
standards.
    All section references refer to sections within this appendix unless 
otherwise stated.

                             1.2 Definitions

    Airflow-control settings are programmed or wired control system 
configurations that control a fan to achieve discrete, differing ranges 
of airflow--often designated for performing a specific function (e.g., 
cooling, heating, or constant circulation)--without manual adjustment 
other than interaction with a user-operable control (i.e., a thermostat) 
that meets the manufacturer specifications for installed-use. For the 
purposes of this appendix, manufacturer specifications for installed-use 
are those found in the product literature shipped with the unit.
    Air sampling device is an assembly consisting of a manifold with 
several branch tubes with multiple sampling holes that draws an air 
sample from a critical location from the unit under test (e.g. indoor 
air inlet, indoor air outlet, outdoor air inlet, etc.).
    Airflow prevention device denotes a device that prevents airflow via 
natural convection by mechanical means, such as an air damper box, or by 
means of changes in duct height, such as an upturned duct.
    Aspirating psychrometer is a piece of equipment with a monitored 
airflow section that draws uniform airflow through the measurement 
section and has probes for measurement of air temperature and humidity.
    Blower coil indoor unit means an indoor unit either with an indoor 
blower housed with the coil or with a separate designated air mover such 
as a furnace or a modular blower (as defined in appendix AA to the 
subpart).
    Blower coil system refers to a split system that includes one or 
more blower coil indoor units.
    Cased coil means a coil-only indoor unit with external cabinetry.
    Coefficient of Performance (COP) means the ratio of the average rate 
of space heating delivered to the average rate of electrical energy 
consumed by the heat pump. These rate quantities must be determined from 
a single test or, if derived via interpolation, must be determined at a 
single set of operating conditions. COP is a dimensionless quantity. 
When determined for a ducted coil-only system, COP must include the 
sections 3.7 and 3.9.1 of this appendix: Default values for the heat 
output and power input of a fan motor.
    Coil-only indoor unit means an indoor unit that is distributed in 
commerce without an indoor blower or separate designated air mover. A 
coil-only indoor unit installed in the field relies on a separately-
installed furnace or a modular blower for indoor air movement. Coil-only 
system refers to a system that includes only (one or more) coil-only 
indoor units.
    Condensing unit removes the heat absorbed by the refrigerant to 
transfer it to the outside environment and consists of an outdoor coil, 
compressor(s), and air moving device.
    Constant-air-volume-rate indoor blower means a fan that varies its 
operating speed to provide a fixed air-volume-rate from a ducted system.
    Continuously recorded, when referring to a dry bulb measurement, dry 
bulb temperature used for test room control, wet bulb temperature, dew 
point temperature, or relative humidity measurements, means that the 
specified value must be sampled at regular intervals that are equal to 
or less than 15 seconds.
    Cooling load factor (CLF) means the ratio having as its numerator 
the total cooling delivered during a cyclic operating interval 
consisting of one ON period and one OFF period, and as its denominator 
the total cooling that would be delivered, given the same ambient 
conditions, had the unit operated continuously at its steady-state, 
space-cooling capacity for the same total time (ON + OFF) interval.
    Crankcase heater means any electrically powered device or mechanism 
for intentionally generating heat within and/or around the compressor 
sump volume. Crankcase heater control may be achieved using a timer or 
may be based on a change in temperature or some other measurable 
parameter, such that the crankcase heater is not required to operate 
continuously. A crankcase heater without controls operates continuously 
when the compressor is not operating.
    Cyclic Test means a test where the unit's compressor is cycled on 
and off for specific time intervals. A cyclic test provides half the 
information needed to calculate a degradation coefficient.
    Damper box means a short section of duct having an air damper that 
meets the performance requirements of section 2.5.7 of this appendix.
    Degradation coefficient (CD) means a parameter used in 
calculating the part load factor.

[[Page 463]]

The degradation coefficient for cooling is denoted by CD\c\. 
The degradation coefficient for heating is denoted by CD\h\.
    Demand-defrost control system means a system that defrosts the heat 
pump outdoor coil-only when measuring a predetermined degradation of 
performance. The heat pump's controls either:
    (1) Monitor one or more parameters that always vary with the amount 
of frost accumulated on the outdoor coil (e.g., coil to air differential 
temperature, coil differential air pressure, outdoor fan power or 
current, optical sensors) at least once for every ten minutes of 
compressor ON-time when space heating or
    (2) operate as a feedback system that measures the length of the 
defrost period and adjusts defrost frequency accordingly. In all cases, 
when the frost parameter(s) reaches a predetermined value, the system 
initiates a defrost. In a demand-defrost control system, defrosts are 
terminated based on monitoring a parameter(s) that indicates that frost 
has been eliminated from the coil. (Note: Systems that vary defrost 
intervals according to outdoor dry-bulb temperature are not demand-
defrost systems.) A demand-defrost control system, which otherwise meets 
the above requirements, may allow time-initiated defrosts if, and only 
if, such defrosts occur after 6 hours of compressor operating time.
    Design heating requirement (DHR) predicts the space heating load of 
a residence when subjected to outdoor design conditions. Estimates for 
the minimum and maximum DHR are provided for six generalized U.S. 
climatic regions in section 4.2 of this appendix.
    Dry-coil tests are cooling mode tests where the wet-bulb temperature 
of the air supplied to the indoor unit is maintained low enough that no 
condensate forms on the evaporator coil.
    Ducted system means an air conditioner or heat pump that is designed 
to be permanently installed equipment and delivers conditioned air to 
the indoor space through a duct(s). The air conditioner or heat pump may 
be either a split-system or a single-package unit.
    Energy efficiency ratio (EER) means the ratio of the average rate of 
space cooling delivered to the average rate of electrical energy 
consumed by the air conditioner or heat pump. Determine these rate 
quantities from a single test or, if derived via interpolation, 
determine at a single set of operating conditions. EER is expressed in 
units of
[GRAPHIC] [TIFF OMITTED] TR05JA17.305

When determined for a ducted coil-only system, EER must include, from 
this appendix, the section 3.3 and 3.5.1 default values for the heat 
output and power input of a fan motor.
    Evaporator coil means an assembly that absorbs heat from an enclosed 
space and transfers the heat to a refrigerant.
    Heat pump means a kind of central air conditioner that utilizes an 
indoor conditioning coil, compressor, and refrigerant-to-outdoor air 
heat exchanger to provide air heating, and may also provide air cooling, 
air dehumidifying, air humidifying, air circulating, and air cleaning.
    Heat pump having a heat comfort controller means a heat pump with 
controls that can regulate the operation of the electric resistance 
elements to assure that the air temperature leaving the indoor section 
does not fall below a specified temperature. Heat pumps that actively 
regulate the rate of electric resistance heating when operating below 
the balance point (as the result of a second stage call from the 
thermostat) but do not operate to maintain a minimum delivery 
temperature are not considered as having a heat comfort controller.
    Heating load factor (HLF) means the ratio having as its numerator 
the total heating delivered during a cyclic operating interval 
consisting of one ON period and one OFF period, and its denominator the 
heating capacity measured at the same test conditions used for the 
cyclic test, multiplied by the total time interval (ON plus OFF) of the 
cyclic-test.
    Heating season means the months of the year that require heating, 
e.g., typically, and roughly, October through April.
    Heating seasonal performance factor (HSPF) means the total space 
heating required during the heating season, expressed in Btu, divided by 
the total electrical energy consumed by the heat pump system during the 
same season, expressed in watt-hours. The HSPF used to evaluate 
compliance with 10 CFR 430.32(c) is based on Region IV and the sampling 
plan stated in 10 CFR 429.16(a). HSPF is determined in accordance with 
appendix M.
    Independent coil manufacturer (ICM) means a manufacturer that 
manufactures indoor units but does not manufacture single-package units 
or outdoor units.
    Indoor unit means a separate assembly of a split system that 
includes--
    (1) An arrangement of refrigerant-to-air heat transfer coil(s) for 
transfer of heat between the refrigerant and the indoor air,
    (2) A condensate drain pan, and may or may not include
    (3) Sheet metal or plastic parts not part of external cabinetry to 
direct/route airflow over the coil(s),
    (4) A cooling mode expansion device,
    (5) External cabinetry, and
    (6) An integrated indoor blower (i.e. a device to move air including 
its associated motor). A separate designated air mover that may be a 
furnace or a modular blower (as defined in appendix AA to the subpart) 
may be

[[Page 464]]

considered to be part of the indoor unit. A service coil is not an 
indoor unit.
    Multi-head mini-split system means a split system that has one 
outdoor unit and that has two or more indoor units connected with a 
single refrigeration circuit. The indoor units operate in unison in 
response to a single indoor thermostat.
    Multiple-circuit (or multi-circuit) system means a split system that 
has one outdoor unit and that has two or more indoor units installed on 
two or more refrigeration circuits such that each refrigeration circuit 
serves a compressor and one and only one indoor unit, and refrigerant is 
not shared from circuit to circuit.
    Multiple-split (or multi-split) system means a split system that has 
one outdoor unit and two or more coil-only indoor units and/or blower 
coil indoor units connected with a single refrigerant circuit. The 
indoor units operate independently and can condition multiple zones in 
response to at least two indoor thermostats or temperature sensors. The 
outdoor unit operates in response to independent operation of the indoor 
units based on control input of multiple indoor thermostats or 
temperature sensors, and/or based on refrigeration circuit sensor input 
(e.g., suction pressure).
    Nominal capacity means the capacity that is claimed by the 
manufacturer on the product name plate. Nominal cooling capacity is 
approximate to the air conditioner cooling capacity tested at A or A2 
condition. Nominal heating capacity is approximate to the heat pump 
heating capacity tested in H12 test (or the optional H1N test).
    Non-ducted indoor unit means an indoor unit that is designed to be 
permanently installed, mounted on room walls and/or ceilings, and that 
directly heats or cools air within the conditioned space.
    Normalized Gross Indoor Fin Surface (NGIFS) means the gross fin 
surface area of the indoor unit coil divided by the cooling capacity 
measured for the A or A2 Test, whichever applies.
    Off-mode power consumption means the power consumption when the unit 
is connected to its main power source but is neither providing cooling 
nor heating to the building it serves.
    Off-mode season means, for central air conditioners other than heat 
pumps, the shoulder season and the entire heating season; and for heat 
pumps, the shoulder season only.
    Outdoor unit means a separate assembly of a split system that 
transfers heat between the refrigerant and the outdoor air, and consists 
of an outdoor coil, compressor(s), an air moving device, and in addition 
for heat pumps, may include a heating mode expansion device, reversing 
valve, and/or defrost controls.
    Outdoor unit manufacturer (OUM) means a manufacturer of single-
package units, outdoor units, and/or both indoor units and outdoor 
units.
    Part-load factor (PLF) means the ratio of the cyclic EER (or COP for 
heating) to the steady-state EER (or COP), where both EERs (or COPs) are 
determined based on operation at the same ambient conditions.
    Seasonal energy efficiency ratio (SEER) means the total heat removed 
from the conditioned space during the annual cooling season, expressed 
in Btu's, divided by the total electrical energy consumed by the central 
air conditioner or heat pump during the same season, expressed in watt-
hours. SEER is determined in accordance with appendix M.
    Service coil means an arrangement of refrigerant-to-air heat 
transfer coil(s), condensate drain pan, sheet metal or plastic parts to 
direct/route airflow over the coil(s), which may or may not include 
external cabinetry and/or a cooling mode expansion device, distributed 
in commerce solely for replacing an uncased coil or cased coil that has 
already been placed into service, and that has been labeled ``for indoor 
coil replacement only'' on the nameplate and in manufacturer technical 
and product literature. The model number for any service coil must 
include some mechanism (e.g., an additional letter or number) for 
differentiating a service coil from a coil intended for an indoor unit.
    Shoulder season means the months of the year in between those months 
that require cooling and those months that require heating, e.g., 
typically, and roughly, April through May, and September through 
October.
    Single-package unit means any central air conditioner or heat pump 
that has all major assemblies enclosed in one cabinet.
    Single-split system means a split system that has one outdoor unit 
and one indoor unit connected with a single refrigeration circuit. 
Small-duct, high-velocity system means a split system for which all 
indoor units are blower coil indoor units that produce at least 1.2 
inches (of water column) of external static pressure when operated at 
the full-load air volume rate certified by the manufacturer of at least 
220 scfm per rated ton of cooling.
    Split system means any air conditioner or heat pump that has at 
least two separate assemblies that are connected with refrigerant piping 
when installed. One of these assemblies includes an indoor coil that 
exchanges heat with the indoor air to provide heating or cooling, while 
one of the others includes an outdoor coil that exchanges heat with the 
outdoor air. Split systems may be either blower coil systems or coil-
only systems.
    Standard Air means dry air having a mass density of 0.075 lb/ft\3\.
    Steady-state test means a test where the test conditions are 
regulated to remain as

[[Page 465]]

constant as possible while the unit operates continuously in the same 
mode.
    Temperature bin means the 5 [deg]F increments that are used to 
partition the outdoor dry-bulb temperature ranges of the cooling 
(=65 [deg]F) and heating (<65 [deg]F) seasons.
    Test condition tolerance means the maximum permissible difference 
between the average value of the measured test parameter and the 
specified test condition.
    Test operating tolerance means the maximum permissible range that a 
measurement may vary over the specified test interval. The difference 
between the maximum and minimum sampled values must be less than or 
equal to the specified test operating tolerance.
    Tested combination means a multi-head mini-split, multi-split, or 
multi-circuit system having the following features:
    (1) The system consists of one outdoor unit with one or more 
compressors matched with between two and five indoor units;
    (2) The indoor units must:
    (i) Collectively, have a nominal cooling capacity greater than or 
equal to 95 percent and less than or equal to 105 percent of the nominal 
cooling capacity of the outdoor unit;
    (ii) Each represent the highest sales volume model family, if this 
is possible while meeting all the requirements of this section. If this 
is not possible, one or more of the indoor units may represent another 
indoor model family in order that all the other requirements of this 
section are met.
    (iii) Individually not have a nominal cooling capacity greater than 
50 percent of the nominal cooling capacity of the outdoor unit, unless 
the nominal cooling capacity of the outdoor unit is 24,000 Btu/h or 
less;
    (iv) Operate at fan speeds consistent with manufacturer's 
specifications; and
    (v) All be subject to the same minimum external static pressure 
requirement while able to produce the same external static pressure at 
the exit of each outlet plenum when connected in a manifold 
configuration as required by the test procedure.
    (3) Where referenced, ``nominal cooling capacity'' means, for indoor 
units, the highest cooling capacity listed in published product 
literature for 95 [deg]F outdoor dry bulb temperature and 80 [deg]F dry 
bulb, 67 [deg]F wet bulb indoor conditions, and for outdoor units, the 
lowest cooling capacity listed in published product literature for these 
conditions. If incomplete or no operating conditions are published, the 
highest (for indoor units) or lowest (for outdoor units) such cooling 
capacity available for sale must be used.
    Time-adaptive defrost control system is a demand-defrost control 
system that measures the length of the prior defrost period(s) and uses 
that information to automatically determine when to initiate the next 
defrost cycle.
    Time-temperature defrost control systems initiate or evaluate 
initiating a defrost cycle only when a predetermined cumulative 
compressor ON-time is obtained. This predetermined ON-time is generally 
a fixed value (e.g., 30, 45, 90 minutes) although it may vary based on 
the measured outdoor dry-bulb temperature. The ON-time counter 
accumulates if controller measurements (e.g., outdoor temperature, 
evaporator temperature) indicate that frost formation conditions are 
present, and it is reset/remains at zero at all other times. In one 
application of the control scheme, a defrost is initiated whenever the 
counter time equals the predetermined ON-time. The counter is reset when 
the defrost cycle is completed.
    In a second application of the control scheme, one or more 
parameters are measured (e.g., air and/or refrigerant temperatures) at 
the predetermined, cumulative, compressor ON-time. A defrost is 
initiated only if the measured parameter(s) falls within a predetermined 
range. The ON-time counter is reset regardless of whether or not a 
defrost is initiated. If systems of this second type use cumulative ON-
time intervals of 10 minutes or less, then the heat pump may qualify as 
having a demand defrost control system (see definition).
    Triple-capacity, northern heat pump means a heat pump that provides 
two stages of cooling and three stages of heating. The two common stages 
for both the cooling and heating modes are the low capacity stage and 
the high capacity stage. The additional heating mode stage is the 
booster capacity stage, which offers the highest heating capacity output 
for a given set of ambient operating conditions.
    Triple-split system means a split system that is composed of three 
separate assemblies: An outdoor fan coil section, a blower coil indoor 
unit, and an indoor compressor section.
    Two-capacity (or two-stage) compressor system means a central air 
conditioner or heat pump that has a compressor or a group of compressors 
operating with only two stages of capacity. For such systems, low 
capacity means the compressor(s) operating at low stage, or at low load 
test conditions. The low compressor stage that operates for heating mode 
tests may be the same or different from the low compressor stage that 
operates for cooling mode tests. For such systems, high capacity means 
the compressor(s) operating at high stage, or at full load test 
conditions.
    Two-capacity, northern heat pump means a heat pump that has a 
factory or field-selectable lock-out feature to prevent space cooling at 
high-capacity. Two-capacity heat pumps having this feature will 
typically have two sets of ratings, one with the feature disabled and 
one with the feature enabled. The heat pump is a two-capacity northern

[[Page 466]]

heat pump only when this feature is enabled at all times. The certified 
indoor coil model number must reflect whether the ratings pertain to the 
lockout enabled option via the inclusion of an extra identifier, such as 
``+LO''. When testing as a two-capacity, northern heat pump, the lockout 
feature must remain enabled for all tests.
    Uncased coil means a coil-only indoor unit without external 
cabinetry.
    Variable refrigerant flow (VRF) system means a multi-split system 
with at least three compressor capacity stages, distributing refrigerant 
through a piping network to multiple indoor blower coil units each 
capable of individual zone temperature control, through proprietary zone 
temperature control devices and a common communications network. Note: 
Single-phase VRF systems less than 65,000 Btu/h are central air 
conditioners and central air conditioning heat pumps.
    Variable-speed compressor system means a central air conditioner or 
heat pump that has a compressor that uses a variable-speed drive to vary 
the compressor speed to achieve variable capacities.
    Wet-coil test means a test conducted at test conditions that 
typically cause water vapor to condense on the test unit evaporator 
coil.

                   2. Testing Overview and Conditions

    (A) Test VRF systems using AHRI 1230-2010 (incorporated by 
reference, see Sec. 430.3) and appendix M. Where AHRI 1230-2010 refers 
to the appendix C therein substitute the provisions of this appendix. In 
cases where there is a conflict, the language of the test procedure in 
this appendix takes precedence over AHRI 1230-2010.
    For definitions use section 1 of appendix M and section 3 of AHRI 
1230-2010 (incorporated by reference, see Sec. 430.3). For rounding 
requirements, refer to Sec. 430.23(m). For determination of certified 
ratings, refer to Sec. 429.16 of this chapter.
    For test room requirements, refer to section 2.1 of this appendix. 
For test unit installation requirements refer to sections 2.2.a, 2.2.b, 
2.2.c, 2.2.1, 2.2.2, 2.2.3(a), 2.2.3(c), 2.2.4, 2.2.5, and 2.4 to 2.12 
of this appendix, and sections 5.1.3 and 5.1.4 of AHRI 1230-2010. The 
``manufacturer's published instructions,'' as stated in section 8.2 of 
ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3) and 
``manufacturer's installation instructions'' discussed in this appendix 
mean the manufacturer's installation instructions that come packaged 
with or appear in the labels applied to the unit. This does not include 
online manuals. Installation instructions that appear in the labels 
applied to the unit take precedence over installation instructions that 
are shipped with the unit.
    For general requirements for the test procedure, refer to section 
3.1 of this appendix, except for sections 3.1.3 and 3.1.4, which are 
requirements for indoor air volume and outdoor air volume. For indoor 
air volume and outdoor air volume requirements, refer instead to section 
6.1.5 (except where section 6.1.5 refers to Table 8, refer instead to 
Table 4 of this appendix) and 6.1.6 of AHRI 1230-2010.
    For the test method, refer to sections 3.3 to 3.5 and 3.7 to 3.13 of 
this appendix. For cooling mode and heating mode test conditions, refer 
to section 6.2 of AHRI 1230-2010. For calculations of seasonal 
performance descriptors, refer to section 4 of this appendix.
    (B) For systems other than VRF, only a subset of the sections listed 
in this test procedure apply when testing and determining represented 
values for a particular unit. Table 1 shows the sections of the test 
procedure that apply to each system. This table is meant to assist 
manufacturers in finding the appropriate sections of the test procedure; 
the appendix sections rather than the table provide the specific 
requirements for testing, and given the varied nature of available 
units, manufacturers are responsible for determining which sections 
apply to each unit tested based on the unit's characteristics. To use 
this table, first refer to the sections listed under ``all units''. Then 
refer to additional requirements based on:
    (1) System configuration(s),
    (2) The compressor staging or modulation capability, and
    (3) Any special features.
    Testing requirements for space-constrained products do not differ 
from similar equipment that is not space-constrained and thus are not 
listed separately in this table. Air conditioners and heat pumps are not 
listed separately in this table, but heating procedures and calculations 
apply only to heat pumps.

                       2.1 Test Room Requirements

    a. Test using two side-by-side rooms: An indoor test room and an 
outdoor test room. For multiple-split, single-zone-multi-coil or multi-
circuit air conditioners and heat pumps, however, use as many indoor 
test rooms as needed to accommodate the total number of indoor units. 
These rooms must comply with the requirements specified in sections 
8.1.2 and 8.1.3 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3).
    b. Inside these test rooms, use artificial loads during cyclic tests 
and frost accumulation tests, if needed, to produce stabilized room air 
temperatures. For one room, select an electric resistance heater(s) 
having a heating capacity that is approximately equal to the heating 
capacity of the test unit's condenser. For the second room, select a 
heater(s) having a capacity that is close to the sensible cooling 
capacity of the test unit's evaporator. Cycle the heater located in the 
same room as the test unit evaporator coil ON and OFF when the test unit 
cycles ON and OFF. Cycle the heater located in the same room as the test 
unit condensing coil ON and OFF when the test unit cycles OFF and ON.

                 2.2 Test Unit Installation Requirements

    a. Install the unit according to section 8.2 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3), subject to the following 
additional requirements:
    (1) When testing split systems, follow the requirements given in 
section 6.1.3.5 of AHRI 210/240-2008 (incorporated by reference, see 
Sec. 430.3). For the vapor refrigerant line(s), use the insulation 
included with the unit; if no insulation is provided, use insulation 
meeting the specifications for the insulation in the installation 
instructions included with the unit by the manufacturer; if no 
insulation is included with the unit and the installation instructions 
do not contain provisions for insulating the line(s), fully insulate the 
vapor refrigerant line(s) with vapor proof insulation having an inside 
diameter that matches the refrigerant tubing and a nominal thickness of 
at least 0.5 inches. For the liquid refrigerant line(s), use the 
insulation included with the unit; if no insulation is provided, use 
insulation meeting the specifications for the insulation in the 
installation instructions included with the unit by the manufacturer; if 
no insulation is included with the unit and the installation 
instructions do not contain provisions for insulating the line(s), leave 
the liquid refrigerant line(s) exposed to the air for air conditioners 
and heat pumps that heat and cool; or, for heating-only heat pumps, 
insulate the liquid refrigerant line(s) with insulation having an inside 
diameter that matches the refrigerant tubing and a nominal thickness of 
at least 0.5 inches. However, these requirements do not take priority 
over instructions for application of insulation for the purpose of 
improving refrigerant temperature measurement accuracy as required by 
sections 2.10.2 and 2.10.3 of this appendix. Insulation must be the same 
for the cooling and heating tests.
    (2) When testing split systems, if the indoor unit does not ship 
with a cooling mode expansion device, test the system using the device 
as specified in the installation instructions provided with the indoor 
unit. If none is specified, test the system using a fixed orifice or 
piston type expansion device that is sized appropriately for the system.
    (3) When testing triple-split systems (see section 1.2 of this 
appendix, Definitions), use the tubing length specified in section 
6.1.3.5 of AHRI 210/240-2008 (incorporated by reference, see Sec. 
430.3) to connect the outdoor coil, indoor compressor section, and 
indoor coil while still meeting the requirement of exposing 10 feet of 
the tubing to outside conditions;
    (4) When testing split systems having multiple indoor coils, connect 
each indoor blower coil unit to the outdoor unit using:
    (a) 25 feet of tubing, or
    (b) tubing furnished by the manufacturer, whichever is longer.
    At least 10 feet of the system interconnection tubing shall be 
exposed to the outside conditions. If they are needed to make a 
secondary measurement of capacity or for verification of refrigerant 
charge, install refrigerant pressure measuring instruments as described 
in section 8.2.5 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3). Section 2.10 of this appendix specifies which secondary 
methods require refrigerant pressure measurements and section 2.2.5.5 of 
this appendix discusses use of pressure measurements to verify charge. 
At a minimum, insulate the low-pressure line(s) of a split system with 
insulation having an inside diameter that matches the refrigerant tubing 
and a nominal thickness of 0.5 inch.
    b. For units designed for both horizontal and vertical installation 
or for both up-flow and down-flow vertical installations, use the 
orientation for testing specified by the manufacturer in the 
certification report. Conduct testing with the following installed:
    (1) The most restrictive filter(s);
    (2) Supplementary heating coils; and
    (3) Other equipment specified as part of the unit, including all 
hardware used by a heat comfort controller if so equipped (see section 1 
of this appendix, Definitions). For small-duct, high-velocity systems, 
configure all balance dampers or restrictor devices on or inside the 
unit to fully open or lowest restriction.
    c. Testing a ducted unit without having an indoor air filter 
installed is permissible as long as the minimum external static pressure 
requirement is adjusted as stated in

[[Page 471]]

Table 4, note 3 (see section 3.1.4 of this appendix). Except as noted in 
section 3.1.10 of this appendix, prevent the indoor air supplementary 
heating coils from operating during all tests. For uncased coils, create 
an enclosure using 1 inch fiberglass foil-faced ductboard having a 
nominal density of 6 pounds per cubic foot. Or alternatively, construct 
an enclosure using sheet metal or a similar material and insulating 
material having a thermal resistance (``R'' value) between 4 and 6 
hr[middot]ft\2\[middot] [deg]F/Btu. Size the enclosure and seal between 
the coil and/or drainage pan and the interior of the enclosure as 
specified in installation instructions shipped with the unit. Also seal 
between the plenum and inlet and outlet ducts.
    d. When testing a coil-only system, install a toroidal-type 
transformer to power the system's low-voltage components, complying with 
any additional requirements for the transformer mentioned in the 
installation manuals included with the unit by the system manufacturer. 
If the installation manuals do not provide specifications for the 
transformer, use a transformer having the following features:
    (1) A nominal volt-amp rating such that the transformer is loaded 
between 25 and 90 percent of this rating for the highest level of power 
measured during the off mode test (section 3.13 of this appendix);
    (2) Designed to operate with a primary input of 230 V, single phase, 
60 Hz; and
    (3) That provides an output voltage that is within the specified 
range for each low-voltage component. Include the power consumption of 
the components connected to the transformer as part of the total system 
power consumption during the off mode tests; do not include the power 
consumed by the transformer when no load is connected to it.
    e. Test an outdoor unit with no match (i.e., that is not distributed 
in commerce with any indoor units) using a coil-only indoor unit with a 
single cooling air volume rate whose coil has:
    (1) Round tubes of outer diameter no less than 0.375 inches, and
    (2) a normalized gross indoor fin surface (NGIFS) no greater than 
1.0 square inches per British thermal unit per hour (sq. in./Btu/hr). 
NGIFS is calculated as follows:
    NGIFS = 2 x Lf x Wf x Nf / Qc(95)
where:

Lf = Indoor coil fin length in inches, also height of the 
          coil transverse to the tubes.
Wf = Indoor coil fin width in inches, also depth of the coil.
Nf = Number of fins.
Qc(95) = the measured space cooling capacity of the tested outdoor unit/
          indoor unit combination as determined from the A2 or A Test 
          whichever applies, Btu/h.

    [fnof]. If the outdoor unit or the outdoor portion of a single-
package unit has a drain pan heater to prevent freezing of defrost 
water, the heater shall be energized, subject to control to de-energize 
it when not needed by the heater's thermostat or the unit's control 
system, for all tests.
    g. If pressure measurement devices are connected to a cooling/
heating heat pump refrigerant circuit, the refrigerant charge 
Mt that could potentially transfer out of the connected 
pressure measurement systems (transducers, gauges, connections, and 
lines) between operating modes must be less than 2 percent of the 
factory refrigerant charge listed on the nameplate of the outdoor unit. 
If the outdoor unit nameplate has no listed refrigerant charge, or the 
heat pump is shipped without a refrigerant charge, use a factory 
refrigerant charge equal to 30 ounces per ton of certified cooling 
capacity. Use Equation 2.2-1 to calculate Mt for heat pumps 
that have a single expansion device located in the outdoor unit to serve 
each indoor unit, and use Equation 2.2-2 to calculate Mt for 
heat pumps that have two expansion devices per indoor unit.

where:

Vi (i=2,3,4. . .) = the internal volume of the pressure 
          measurement system (pressure lines, fittings, and gauge and/or 
          transducer) at the location i (as indicated in Table 2), 
          (cubic inches)
fi (i=5,6) = 0 if the pressure measurement system is pitched 
          upwards from the pressure tap location to the gauge or 
          transducer, 1 if it is not.
r = the density associated with liquid refrigerant at 100 [deg]F bubble 
          point conditions (ounces per cubic inch)

                 Table 2--Pressure Measurement Locations
------------------------------------------------------------------------
                              Location
------------------------------------------------------------------------
Compressor Discharge...............................................    1
Between Outdoor Coil and Outdoor Expansion Valve(s)................    2
Liquid Service Valve...............................................    3
Indoor Coil Inlet..................................................    4
Indoor Coil Outlet.................................................    5
Common Suction Port (i.e. vapor service valve).....................    6
Compressor Suction.................................................    7
------------------------------------------------------------------------

    Calculate the internal volume of each pressure measurement system 
using internal volume reported for pressure transducers and gauges in 
product literature, if available. If such information is not available, 
use the value of 0.1 cubic inches internal volume for each pressure 
transducer, and 0.2 cubic inches for each pressure gauge.
    In addition, for heat pumps that have a single expansion device 
located in the outdoor unit to serve each indoor unit, the internal 
volume of the pressure system at location 2 (as indicated in Table 2) 
must be no more than 1 cubic inch. Once the pressure measurement lines 
are set up, no change should be made until all tests are finished.

                     2.2.1 Defrost Control Settings

    Set heat pump defrost controls at the normal settings which most 
typify those encountered in generalized climatic region IV. (Refer to 
Figure 1 and Table 20 of section 4.2 of this appendix for information on 
region IV.) For heat pumps that use a time-adaptive defrost control 
system (see section 1.2 of this appendix, Definitions), the manufacturer 
must specify in the certification report the frosting interval to be 
used during frost accumulation tests and provide the procedure for 
manually initiating the defrost at the specified time.

2.2.2 Special Requirements for Units Having a Multiple-Speed Outdoor Fan

    Configure the multiple-speed outdoor fan according to the 
installation manual included with the unit by the manufacturer, and 
thereafter, leave it unchanged for all tests. The controls of the unit 
must regulate the operation of the outdoor fan during all lab tests 
except dry coil cooling mode tests. For dry coil cooling mode tests, the 
outdoor fan must operate at the same speed used during the required wet 
coil test conducted at the same outdoor test conditions.

  2.2.3 Special Requirements for Multi-Split Air Conditioners and Heat 
   Pumps and Ducted Systems Using a Single Indoor Section Containing 
 Multiple Indoor Blowers That Would Normally Operate Using Two or More 
                           Indoor Thermostats

    Because these systems will have more than one indoor blower and 
possibly multiple outdoor fans and compressor systems, references in 
this test procedure to a singular indoor blower, outdoor fan, and/or 
compressor means all indoor blowers, all outdoor fans, and all 
compressor systems that are energized during the test.
    a. Additional requirements for multi-split air conditioners and heat 
pumps. For any test where the system is operated at part load (i.e., one 
or more compressors ``off'', operating at the intermediate or minimum 
compressor speed, or at low compressor capacity), record the indoor 
coil(s) that are not providing heating or cooling during the test. For 
variable-speed systems, the manufacturer must designate in the 
certification report at least one indoor unit that is not providing 
heating or cooling for all tests conducted at minimum compressor speed.
    b. Additional requirements for ducted split systems with a single 
indoor unit containing multiple indoor blowers (or for single-package 
units with an indoor section containing multiple indoor blowers) where 
the indoor blowers are designed to cycle on and off independently of one 
another and are not controlled such that all indoor blowers are 
modulated to always operate at the same air volume rate or speed. For 
any test where the system is operated at its lowest capacity--i.e., the 
lowest total air volume rate allowed when operating the single-speed 
compressor or when operating at low compressor capacity--indoor blowers 
accounting for at least one-third of the full-load air volume rate must 
be turned off unless prevented by the controls of the unit. In such 
cases, turn off as many indoor blowers as permitted by the unit's 
controls. Where more than one option exists for meeting this ``off'' 
requirement, the manufacturer shall indicate in its certification report 
which indoor blower(s) are turned off. The chosen configuration shall 
remain unchanged for all tests conducted at the same lowest capacity 
configuration. For any indoor coil turned off during a test, cease 
forced airflow through any outlet duct connected to a switched-off 
indoor blower.
    c. For test setups where the laboratory's physical limitations 
requires use of more than the required line length of 25 feet as listed 
in section 2.2.a(4) of this appendix, then the actual refrigerant line 
length used by the laboratory may exceed the required length and the 
refrigerant line length correction factors in Table 4 of AHRI 1230-2010 
are applied to the cooling capacity measured for each cooling mode test.

2.2.4 Wet-Bulb Temperature Requirements for the Air Entering the Indoor 
                            and Outdoor Coils

                       2.2.4.1 Cooling Mode Tests

    For wet-coil cooling mode tests, regulate the water vapor content of 
the air entering the indoor unit so that the wet-bulb temperature is as 
listed in Tables 5 to 8. As

[[Page 473]]

noted in these same tables, achieve a wet-bulb temperature during dry-
coil cooling mode tests that results in no condensate forming on the 
indoor coil. Controlling the water vapor content of the air entering the 
outdoor side of the unit is not required for cooling mode tests except 
when testing:
    (1) Units that reject condensate to the outdoor coil during wet coil 
tests. Tables 5-8 list the applicable wet-bulb temperatures.
    (2) Single-package units where all or part of the indoor section is 
located in the outdoor test room. The average dew point temperature of 
the air entering the outdoor coil during wet coil tests must be within 
3.0 [deg]F of the average dew point temperature of 
the air entering the indoor coil over the 30-minute data collection 
interval described in section 3.3 of this appendix. For dry coil tests 
on such units, it may be necessary to limit the moisture content of the 
air entering the outdoor coil of the unit to meet the requirements of 
section 3.4 of this appendix.

                       2.2.4.2 Heating Mode Tests

    For heating mode tests, regulate the water vapor content of the air 
entering the outdoor unit to the applicable wet-bulb temperature listed 
in Tables 12 to 15. The wet-bulb temperature entering the indoor side of 
the heat pump must not exceed 60 [deg]F. Additionally, if the Outdoor 
Air Enthalpy test method (section 2.10.1 of this appendix) is used while 
testing a single-package heat pump where all or part of the outdoor 
section is located in the indoor test room, adjust the wet-bulb 
temperature for the air entering the indoor side to yield an indoor-side 
dew point temperature that is as close as reasonably possible to the dew 
point temperature of the outdoor-side entering air.

           2.2.5 Additional Refrigerant Charging Requirements

                2.2.5.1 Instructions To Use for Charging

    a. Where the manufacturer's installation instructions contain two 
sets of refrigerant charging criteria, one for field installations and 
one for lab testing, use the field installation criteria.
    b. For systems consisting of an outdoor unit manufacturer's outdoor 
section and indoor section with differing charging procedures, adjust 
the refrigerant charge per the outdoor installation instructions.
    c. For systems consisting of an outdoor unit manufacturer's outdoor 
unit and an independent coil manufacturer's indoor unit with differing 
charging procedures, adjust the refrigerant charge per the indoor unit's 
installation instructions. If instructions are provided only with the 
outdoor unit or are provided only with an independent coil 
manufacturer's indoor unit, then use the provided instructions.

                   2.2.5.2 Test(s) To Use for Charging

    a. Use the tests or operating conditions specified in the 
manufacturer's installation instructions for charging. The 
manufacturer's installation instructions may specify use of tests other 
than the A or A2 test for charging, but, unless the unit is a 
heating-only heat pump, the air volume rate must be determined by the A 
or A2 test as specified in section 3.1 of this appendix.
    b. If the manufacturer's installation instructions do not specify a 
test or operating conditions for charging or there are no manufacturer's 
instructions, use the following test(s):
    (1) For air conditioners or cooling and heating heat pumps, use the 
A or A2 test.
    (2) For cooling and heating heat pumps that do not operate in the H1 
or H12 test (e.g. due to shut down by the unit limiting 
devices) when tested using the charge determined at the A or 
A2 test, and for heating-only heat pumps, use the H1 or 
H12 test.

            2.2.5.3 Parameters To Set and Their Target Values

    a. Consult the manufacturer's installation instructions regarding 
which parameters (e.g., superheat) to set and their target values. If 
the instructions provide ranges of values, select target values equal to 
the midpoints of the provided ranges.
    b. In the event of conflicting information between charging 
instructions (i.e., multiple conditions given for charge adjustment 
where all conditions specified cannot be met), follow the following 
hierarchy.
    (1) For fixed orifice systems:
    (i) Superheat
    (ii) High side pressure or corresponding saturation or dew-point 
temperature
    (iii) Low side pressure or corresponding saturation or dew-point 
temperature
    (iv) Low side temperature
    (v) High side temperature
    (vi) Charge weight
    (2) For expansion valve systems:
    (i) Subcooling
    (ii) High side pressure or corresponding saturation or dew-point 
temperature
    (iii) Low side pressure or corresponding saturation or dew-point 
temperature
    (iv) Approach temperature (difference between temperature of liquid 
leaving condenser and condenser average inlet air temperature)
    (v) Charge weight
    c. If there are no installation instructions and/or they do not 
provide parameters and target values, set superheat to a target value of 
12 [deg]F for fixed orifice systems or set subcooling to a target value 
of 10 [deg]F for expansion valve systems.

[[Page 474]]

                       2.2.5.4 Charging Tolerances

    a. If the manufacturer's installation instructions specify 
tolerances on target values for the charging parameters, set the values 
within these tolerances.
    b. Otherwise, set parameter values within the following test 
condition tolerances for the different charging parameters:
1. Superheat:  2.0 [deg]F
2. Subcooling:  2.0 [deg]F
3. High side pressure or corresponding saturation or dew point 
temperature:  4.0 psi or  
1.0 [deg]F
4. Low side pressure or corresponding saturation or dew point 
temperature:  2.0 psi or  
0.8 [deg]F
5. High side temperature: 2.0 [deg]F
6. Low side temperature: 2.0 [deg]F
7. Approach temperature:  1.0 [deg]F
8. Charge weight:  2.0 ounce

                  2.2.5.5 Special Charging Instructions

                    a. Cooling and Heating Heat Pumps

    If, using the initial charge set in the A or A2 test, the 
conditions are not within the range specified in manufacturer's 
installation instructions for the H1 or H12 test, make as 
small as possible an adjustment to obtain conditions for this test in 
the specified range. After this adjustment, recheck conditions in the A 
or A2 test to confirm that they are still within the 
specified range for the A or A2 test.

                        b. Single-Package Systems

    Unless otherwise directed by the manufacturer's installation 
instructions, install one or more refrigerant line pressure gauges 
during the setup of the unit, located depending on the parameters used 
to verify or set charge, as described:
    (1) Install a pressure gauge at the location of the service valve on 
the liquid line if charging is on the basis of subcooling, or high side 
pressure or corresponding saturation or dew point temperature;
    (2) Install a pressure gauge at the location of the service valve on 
the suction line if charging is on the basis of superheat, or low side 
pressure or corresponding saturation or dew point temperature.
    Use methods for installing pressure gauge(s) at the required 
location(s) as indicated in manufacturer's instructions if specified.

           2.2.5.6 Near-Azeotropic and Zeotropic Refrigerants.

    Perform charging of near-azeotropic and zeotropic refrigerants only 
with refrigerant in the liquid state.

               2.2.5.7 Adjustment of Charge Between Tests.

    After charging the system as described in this test procedure, use 
the set refrigerant charge for all tests used to determine performance. 
Do not adjust the refrigerant charge at any point during testing. If 
measurements indicate that refrigerant charge has leaked during the 
test, repair the refrigerant leak, repeat any necessary set-up steps, 
and repeat all tests.

                      2.3 Indoor Air Volume Rates.

    If a unit's controls allow for overspeeding the indoor blower 
(usually on a temporary basis), take the necessary steps to prevent 
overspeeding during all tests.

                           2.3.1 Cooling Tests

    a. Set indoor blower airflow-control settings (e.g., fan motor pin 
settings, fan motor speed) according to the requirements that are 
specified in section 3.1.4 of this appendix.
    b. Express the Cooling full-load air volume rate, the Cooling 
Minimum Air Volume Rate, and the Cooling Intermediate Air Volume Rate in 
terms of standard air.

                           2.3.2 Heating Tests

    a. Set indoor blower airflow-control settings (e.g., fan motor pin 
settings, fan motor speed) according to the requirements that are 
specified in section 3.1.4 of this appendix.
    b. Express the heating full-load air volume rate, the heating 
minimum air volume rate, the heating intermediate air volume rate, and 
the heating nominal air volume rate in terms of standard air.

            2.4 Indoor Coil Inlet and Outlet Duct Connections

    Insulate and/or construct the outlet plenum as described in section 
2.4.1 of this appendix and, if installed, the inlet plenum described in 
section 2.4.2 of this appendix with thermal insulation having a nominal 
overall resistance (R-value) of at least 19 hr[middot]ft\2\[middot] 
[deg]F/Btu.

                 2.4.1 Outlet Plenum for the Indoor Unit

    a. Attach a plenum to the outlet of the indoor coil. (Note: For some 
packaged systems, the indoor coil may be located in the outdoor test 
room.)
    b. For systems having multiple indoor coils, or multiple indoor 
blowers within a single indoor section, attach a plenum to each indoor 
coil or indoor blower outlet. In order to reduce the number of required 
airflow measurement apparati (section 2.6 of this appendix), each such 
apparatus may serve multiple outlet plenums connected to a single common 
duct leading to the apparatus. More than one indoor test room may be 
used, which may use one or more common ducts leading to one or more 
airflow measurement apparati within each test room that contains 
multiple indoor coils. At the plane where each plenum enters a common 
duct, install an adjustable airflow damper and use

[[Page 475]]

it to equalize the static pressure in each plenum. Each outlet air 
temperature grid (section 2.5.4 of this appendix) and airflow measuring 
apparatus are located downstream of the inlet(s) to the common duct. For 
multiple-circuit (or multi-circuit) systems for which each indoor coil 
outlet is measured separately and its outlet plenum is not connected to 
a common duct connecting multiple outlet plenums, the outlet air 
temperature grid and airflow measuring apparatus must be installed at 
each outlet plenum.
    c. For small-duct, high-velocity systems, install an outlet plenum 
that has a diameter that is equal to or less than the value listed in 
Table 3. The limit depends only on the Cooling full-load air volume rate 
(see section 3.1.4.1.1 of this appendix) and is effective regardless of 
the flange dimensions on the outlet of the unit (or an air supply plenum 
adapter accessory, if installed in accordance with the manufacturer's 
installation instructions).
    d. Add a static pressure tap to each face of the (each) outlet 
plenum, if rectangular, or at four evenly distributed locations along 
the circumference of an oval or round plenum. Create a manifold that 
connects the four static pressure taps. Figure 9 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3) shows allowed options for 
the manifold configuration. The cross-sectional dimensions of plenum 
shall be equal to the dimensions of the indoor unit outlet. See Figures 
7a, 7b, and 7c of ANSI/ASHRAE 37-2009 for the minimum length of the 
(each) outlet plenum and the locations for adding the static pressure 
taps for ducted blower coil indoor units and single-package systems. See 
Figure 8 of ANSI/ASHRAE 37-2009 for coil-only indoor units.

                 2.4.2 Inlet Plenum for the Indoor Unit

    Install an inlet plenum when testing a coil-only indoor unit, a 
ducted blower coil indoor unit, or a single-package system. See Figures 
7b and 7c of ANSI/ASHRAE 37-2009 for cross-sectional dimensions, the 
minimum length of the inlet plenum, and the locations of the static-
pressure taps for ducted blower coil indoor units and single-package 
systems. See Figure 8 of ANSI/ASHRAE 37-2009 for coil-only indoor units. 
The inlet plenum duct size shall equal the size of the inlet opening of 
the air-handling (blower coil) unit or furnace. For a ducted blower coil 
indoor unit the set up may omit the inlet plenum if an inlet airflow 
prevention device is installed with a straight internally unobstructed 
duct on its outlet end with a minimum length equal to 1.5 times the 
square root of the cross-sectional area of the indoor unit inlet. See 
section 2.5.1.2 of this appendix for requirements for the locations of 
static pressure taps built into the inlet airflow prevention device. For 
all of these arrangements, make a manifold that connects the four 
static-pressure taps using one of the three configurations specified in 
section 2.4.1.d of this appendix. Never use an inlet plenum when testing 
non-ducted indoor units.

2.5 Indoor Coil Air Property Measurements and Airflow Prevention Devices

    Follow instructions for indoor coil air property measurements as 
described in section 2.14 of this appendix, unless otherwise instructed 
in this section.
    a. Measure the dry-bulb temperature and water vapor content of the 
air entering and leaving the indoor coil. If needed, use an air sampling 
device to divert air to a sensor(s) that measures the water vapor 
content of the air. See section 5.3 of ANSI/ASHRAE 41.1-2013 
(incorporated by reference, see Sec. 430.3) for guidance on 
constructing an air sampling device. No part of the air sampling device 
or the tubing transferring the sampled air to the sensor shall be within 
two inches of the test chamber floor, and the transfer tubing shall be 
insulated. The sampling device may also be used for measurement of dry 
bulb temperature by transferring the sampled air to a remotely located 
sensor(s). The air sampling device and the remotely located temperature 
sensor(s) may be used to determine the entering air dry bulb temperature 
during any test. The air sampling device and the remotely located 
sensor(s) may be used to determine the leaving air dry bulb temperature 
for all tests except:
    (1) Cyclic tests; and
    (2) Frost accumulation tests.
    b. Install grids of temperature sensors to measure dry bulb 
temperatures of both the entering and leaving airstreams of the indoor 
unit. These grids of dry bulb temperature sensors may be used to measure 
average dry bulb temperature entering and leaving the indoor unit in all 
cases (as an alternative to the dry bulb sensor measuring the sampled 
air). The leaving airstream grid is required for measurement of average 
dry bulb temperature leaving the indoor unit for the two special cases 
noted above. The grids are

[[Page 476]]

also required to measure the air temperature distribution of the 
entering and leaving airstreams as described in sections 3.1.8 and 3.1.9 
of this appendix. Two such grids may applied as a thermopile, to 
directly obtain the average temperature difference rather than directly 
measuring both entering and leaving average temperatures.
    c. Use of airflow prevention devices. Use an inlet and outlet air 
damper box, or use an inlet upturned duct and an outlet air damper box 
when conducting one or both of the cyclic tests listed in sections 3.2 
and 3.6 of this appendix on ducted systems. If not conducting any cyclic 
tests, an outlet air damper box is required when testing ducted and non-
ducted heat pumps that cycle off the indoor blower during defrost cycles 
and there is no other means for preventing natural or forced convection 
through the indoor unit when the indoor blower is off. Never use an 
inlet damper box or an inlet upturned duct when testing non-ducted 
indoor units. An inlet upturned duct is a length of ductwork installed 
upstream from the inlet such that the indoor duct inlet opening, facing 
upwards, is sufficiently high to prevent natural convection transfer out 
of the duct. If an inlet upturned duct is used, install a dry bulb 
temperature sensor near the inlet opening of the indoor duct at a 
centerline location not higher than the lowest elevation of the duct 
edges at the inlet, and ensure that any pair of 5-minute averages of the 
dry bulb temperature at this location, measured at least every minute 
during the compressor OFF period of the cyclic test, do not differ by 
more than 1.0 [deg]F.

2.5.1 Test Set-Up on the Inlet Side of the Indoor Coil: For Cases Where 
            the Inlet Airflow Prevention Device Is Installed

    a. Install an airflow prevention device as specified in section 
2.5.1.1 or 2.5.1.2 of this appendix, whichever applies.
    b. For an inlet damper box, locate the grid of entering air dry-bulb 
temperature sensors, if used, and the air sampling device, or the sensor 
used to measure the water vapor content of the inlet air, at a location 
immediately upstream of the damper box inlet. For an inlet upturned 
duct, locate the grid of entering air dry-bulb temperature sensors, if 
used, and the air sampling device, or the sensor used to measure the 
water vapor content of the inlet air, at a location at least one foot 
downstream from the beginning of the insulated portion of the duct but 
before the static pressure measurement.

         2.5.1.1 If the Section 2.4.2 Inlet Plenum Is Installed

    Construct the airflow prevention device having a cross-sectional 
flow area equal to or greater than the flow area of the inlet plenum. 
Install the airflow prevention device upstream of the inlet plenum and 
construct ductwork connecting it to the inlet plenum. If needed, use an 
adaptor plate or a transition duct section to connect the airflow 
prevention device with the inlet plenum. Insulate the ductwork and inlet 
plenum with thermal insulation that has a nominal overall resistance (R-
value) of at least 19 hr [middot] ft\2\ [middot] [deg]F/Btu.

       2.5.1.2 If the Section 2.4.2 Inlet Plenum Is Not Installed

    Construct the airflow prevention device having a cross-sectional 
flow area equal to or greater than the flow area of the air inlet of the 
indoor unit. Install the airflow prevention device immediately upstream 
of the inlet of the indoor unit. If needed, use an adaptor plate or a 
short transition duct section to connect the airflow prevention device 
with the unit's air inlet. Add static pressure taps at the center of 
each face of a rectangular airflow prevention device, or at four evenly 
distributed locations along the circumference of an oval or round 
airflow prevention device. Locate the pressure taps at a distance from 
the indoor unit inlet equal to 0.5 times the square root of the cross 
sectional area of the indoor unit inlet. This location must be between 
the damper and the inlet of the indoor unit, if a damper is used. Make a 
manifold that connects the four static pressure taps using one of the 
configurations shown in Figure 9 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3). Insulate the ductwork with thermal 
insulation that has a nominal overall resistance (R-value) of at least 
19 hr [middot] ft\2\ [middot] [deg]F/Btu.

2.5.2 Test Set-Up on the Inlet Side of the Indoor Unit: for Cases Where 
                No Airflow Prevention Device is Installed

    If using the section 2.4.2 inlet plenum and a grid of dry bulb 
temperature sensors, mount the grid at a location upstream of the static 
pressure taps described in section 2.4.2 of this appendix, preferably at 
the entrance plane of the inlet plenum. If the section 2.4.2 inlet 
plenum is not used (i.e. for non-ducted units) locate a grid 
approximately 6 inches upstream of the indoor unit inlet. In the case of 
a system having multiple non-ducted indoor units, do this for each 
indoor unit. Position an air sampling device, or the sensor used to 
measure the water vapor content of the inlet air, immediately upstream 
of the (each) entering air dry-bulb temperature sensor grid. If a grid 
of sensors is not used, position the entering air sampling device (or 
the sensor used to measure the water vapor content of the inlet air) as 
if the grid were present.

[[Page 477]]

        2.5.3 Indoor Coil Static Pressure Difference Measurement

    Fabricate pressure taps meeting all requirements described in 
section 6.5.2 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3) and illustrated in Figure 2A of AMCA 210-2007 (incorporated 
by reference, see Sec. 430.3), however, if adhering strictly to the 
description in section 6.5.2 of ANSI/ASHRAE 37-2009, the minimum 
pressure tap length of 2.5 times the inner diameter of Figure 2A of AMCA 
210-2007 is waived. Use a differential pressure measuring instrument 
that is accurate to within 0.01 inches of water 
and has a resolution of at least 0.01 inches of water to measure the 
static pressure difference between the indoor coil air inlet and outlet. 
Connect one side of the differential pressure instrument to the 
manifolded pressure taps installed in the outlet plenum. Connect the 
other side of the instrument to the manifolded pressure taps located in 
either the inlet plenum or incorporated within the airflow prevention 
device. For non-ducted indoor units that are tested with multiple outlet 
plenums, measure the static pressure within each outlet plenum relative 
to the surrounding atmosphere.

         2.5.4 Test Set-Up on the Outlet Side of the Indoor Coil

    a. Install an interconnecting duct between the outlet plenum 
described in section 2.4.1 of this appendix and the airflow measuring 
apparatus described below in section 2.6 of this appendix. The cross-
sectional flow area of the interconnecting duct must be equal to or 
greater than the flow area of the outlet plenum or the common duct used 
when testing non-ducted units having multiple indoor coils. If needed, 
use adaptor plates or transition duct sections to allow the connections. 
To minimize leakage, tape joints within the interconnecting duct (and 
the outlet plenum). Construct or insulate the entire flow section with 
thermal insulation having a nominal overall resistance (R-value) of at 
least 19 hr[middot]ft\2\[middot] [deg]F/Btu.
    b. Install a grid(s) of dry-bulb temperature sensors inside the 
interconnecting duct. Also, install an air sampling device, or the 
sensor(s) used to measure the water vapor content of the outlet air, 
inside the interconnecting duct. Locate the dry-bulb temperature grid(s) 
upstream of the air sampling device (or the in-duct sensor(s) used to 
measure the water vapor content of the outlet air). Turn off the sampler 
fan motor during the cyclic tests. Air leaving an indoor unit that is 
sampled by an air sampling device for remote water-vapor-content 
measurement must be returned to the interconnecting duct at a location:
    (1) Downstream of the air sampling device;
    (2) On the same side of the outlet air damper as the air sampling 
device; and
    (3) Upstream of the section 2.6 airflow measuring apparatus.

        2.5.4.1 Outlet Air Damper Box Placement and Requirements

    If using an outlet air damper box (see section 2.5 of this 
appendix), the leakage rate from the combination of the outlet plenum, 
the closed damper, and the duct section that connects these two 
components must not exceed 20 cubic feet per minute when a negative 
pressure of 1 inch of water column is maintained at the plenum's inlet.

       2.5.4.2 Procedures To Minimize Temperature Maldistribution

    Use these procedures if necessary to correct temperature 
maldistributions. Install a mixing device(s) upstream of the outlet air, 
dry-bulb temperature grid (but downstream of the outlet plenum static 
pressure taps). Use a perforated screen located between the mixing 
device and the dry-bulb temperature grid, with a maximum open area of 40 
percent. One or both items should help to meet the maximum outlet air 
temperature distribution specified in section 3.1.8 of this appendix. 
Mixing devices are described in sections 5.3.2 and 5.3.3 of ANSI/ASHRAE 
41.1-2013 and section 5.2.2 of ASHRAE 41.2-1987 (RA 1992) (incorporated 
by reference, see Sec. 430.3).

                     2.5.4.3 Minimizing Air Leakage

    For small-duct, high-velocity systems, install an air damper near 
the end of the interconnecting duct, just prior to the transition to the 
airflow measuring apparatus of section 2.6 of this appendix. To minimize 
air leakage, adjust this damper such that the pressure in the receiving 
chamber of the airflow measuring apparatus is no more than 0.5 inch of 
water higher than the surrounding test room ambient. If applicable, in 
lieu of installing a separate damper, use the outlet air damper box of 
sections 2.5 and 2.5.4.1 of this appendix if it allows variable 
positioning. Also apply these steps to any conventional indoor blower 
unit that creates a static pressure within the receiving chamber of the 
airflow measuring apparatus that exceeds the test room ambient pressure 
by more than 0.5 inches of water column.

                 2.5.5 Dry Bulb Temperature Measurement

    a. Measure dry bulb temperatures as specified in sections 4, 5.3, 6, 
and 7 of ANSI/ASHRAE 41.1-2013 (incorporated by reference, see Sec. 
430.3).
    b. Distribute the sensors of a dry-bulb temperature grid over the 
entire flow area. The required minimum is 9 sensors per grid.

                  2.5.6 Water Vapor Content Measurement

    Determine water vapor content by measuring dry-bulb temperature 
combined with

[[Page 478]]

the air wet-bulb temperature, dew point temperature, or relative 
humidity. If used, construct and apply wet-bulb temperature sensors as 
specified in sections 4, 5, 6, 7.2, 7.3, and 7.4 of ASHRAE 41.6-2014 
(incorporated by reference, see Sec. 430.3). The temperature sensor 
(wick removed) must be accurate to within 0.2 
[deg]F. If used, apply dew point hygrometers as specified in sections 4, 
5, 6, 7.1, and 7.4 of ASHRAE 41.6-2014 (incorporated by reference, see 
Sec. 430.3). The dew point hygrometers must be accurate to within 
0.4 [deg]F when operated at conditions that result 
in the evaluation of dew points above 35 [deg]F. If used, a relative 
humidity (RH) meter must be accurate to within 0.7% RH. Other means to determine the psychrometric 
state of air may be used as long as the measurement accuracy is 
equivalent to or better than the accuracy achieved from using a wet-bulb 
temperature sensor that meets the above specifications.

              2.5.7 Air Damper Box Performance Requirements

    If used (see section 2.5 of this appendix), the air damper box(es) 
must be capable of being completely opened or completely closed within 
10 seconds for each action.

                     2.6 Airflow Measuring Apparatus

    a. Fabricate and operate an airflow measuring apparatus as specified 
in section 6.2 and 6.3 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3). Place the static pressure taps and position 
the diffusion baffle (settling means) relative to the chamber inlet as 
indicated in Figure 12 of AMCA 210-2007 and/or Figure 14 of ASHRAE 41.2-
1987 (RA 1992) (incorporated by reference, see Sec. 430.3). When 
measuring the static pressure difference across nozzles and/or velocity 
pressure at nozzle throats using electronic pressure transducers and a 
data acquisition system, if high frequency fluctuations cause 
measurement variations to exceed the test tolerance limits specified in 
section 9.2 and Table 2 of ANSI/ASHRAE 37-2009, dampen the measurement 
system such that the time constant associated with response to a step 
change in measurement (time for the response to change 63% of the way 
from the initial output to the final output) is no longer than five 
seconds.
    b. Connect the airflow measuring apparatus to the interconnecting 
duct section described in section 2.5.4 of this appendix. See sections 
6.1.1, 6.1.2, and 6.1.4, and Figures 1, 2, and 4 of ANSI/ASHRAE 37-2009; 
and Figures D1, D2, and D4 of AHRI 210/240-2008 (incorporated by 
reference, see Sec. 430.3) for illustrative examples of how the test 
apparatus may be applied within a complete laboratory set-up. Instead of 
following one of these examples, an alternative set-up may be used to 
handle the air leaving the airflow measuring apparatus and to supply 
properly conditioned air to the test unit's inlet. The alternative set-
up, however, must not interfere with the prescribed means for measuring 
airflow rate, inlet and outlet air temperatures, inlet and outlet water 
vapor contents, and external static pressures, nor create abnormal 
conditions surrounding the test unit. (Note: Do not use an enclosure as 
described in section 6.1.3 of ANSI/ASHRAE 37-2009 when testing triple-
split units.)

                      2.7 Electrical Voltage Supply

    Perform all tests at the voltage specified in section 6.1.3.2 of 
AHRI 210/240-2008 (incorporated by reference, see Sec. 430.3) for 
``Standard Rating Tests.'' If either the indoor or the outdoor unit has 
a 208V or 200V nameplate voltage and the other unit has a 230V nameplate 
rating, select the voltage supply on the outdoor unit for testing. 
Otherwise, supply each unit with its own nameplate voltage. Measure the 
supply voltage at the terminals on the test unit using a volt meter that 
provides a reading that is accurate to within 1.0 
percent of the measured quantity.

              2.8 Electrical Power and Energy Measurements

    a. Use an integrating power (watt-hour) measuring system to 
determine the electrical energy or average electrical power supplied to 
all components of the air conditioner or heat pump (including auxiliary 
components such as controls, transformers, crankcase heater, integral 
condensate pump on non-ducted indoor units, etc.). The watt-hour 
measuring system must give readings that are accurate to within 0.5 percent. For cyclic tests, this accuracy is required 
during both the ON and OFF cycles. Use either two different scales on 
the same watt-hour meter or two separate watt-hour meters. Activate the 
scale or meter having the lower power rating within 15 seconds after 
beginning an OFF cycle. Activate the scale or meter having the higher 
power rating within 15 seconds prior to beginning an ON cycle. For 
ducted blower coil systems, the ON cycle lasts from compressor ON to 
indoor blower OFF. For ducted coil-only systems, the ON cycle lasts from 
compressor ON to compressor OFF. For non-ducted units, the ON cycle 
lasts from indoor blower ON to indoor blower OFF. When testing air 
conditioners and heat pumps having a variable-speed compressor, avoid 
using an induction watt/watt-hour meter.
    b. When performing section 3.5 and/or 3.8 cyclic tests on non-ducted 
units, provide instrumentation to determine the average electrical power 
consumption of the indoor blower motor to within 1.0 percent. If required according to sections 3.3, 3.4, 
3.7, 3.9.1 of this appendix, and/or 3.10 of this appendix, this same 
instrumentation requirement (to


[[Page 479]]

determine the average electrical power consumption of the indoor blower 
motor to within 1.0 percent) applies when testing 
air conditioners and heat pumps having a variable-speed constant-air-
volume-rate indoor blower or a variable-speed, variable-air-volume-rate 
indoor blower.

                          2.9 Time Measurements

    Make elapsed time measurements using an instrument that yields 
readings accurate to within 0.2 percent.

   2.10 Test Apparatus for the Secondary Space Conditioning Capacity 
                               Measurement

    For all tests, use the indoor air enthalpy method to measure the 
unit's capacity. This method uses the test set-up specified in sections 
2.4 to 2.6 of this appendix. In addition, for all steady-state tests, 
conduct a second, independent measurement of capacity as described in 
section 3.1.1 of this appendix. For split systems, use one of the 
following secondary measurement methods: Outdoor air enthalpy method, 
compressor calibration method, or refrigerant enthalpy method. For 
single-package units, use either the outdoor air enthalpy method or the 
compressor calibration method as the secondary measurement.

                   2.10.1 Outdoor Air Enthalpy Method

    a. To make a secondary measurement of indoor space conditioning 
capacity using the outdoor air enthalpy method, do the following:
    (1) Measure the electrical power consumption of the test unit;
    (2) Measure the air-side capacity at the outdoor coil; and
    (3) Apply a heat balance on the refrigerant cycle.
    b. The test apparatus required for the outdoor air enthalpy method 
is a subset of the apparatus used for the indoor air enthalpy method. 
Required apparatus includes the following:
    (1) On the outlet side, an outlet plenum containing static pressure 
taps (sections 2.4, 2.4.1, and 2.5.3 of this appendix),
    (2) An airflow measuring apparatus (section 2.6 of this appendix),
    (3) A duct section that connects these two components and itself 
contains the instrumentation for measuring the dry-bulb temperature and 
water vapor content of the air leaving the outdoor coil (sections 2.5.4, 
2.5.5, and 2.5.6 of this appendix), and
    (4) On the inlet side, a sampling device and temperature grid 
(section 2.11.b of this appendix).
    c. During the free outdoor air tests described in sections 3.11.1 
and 3.11.1.1 of this appendix, measure the evaporator and condenser 
temperatures or pressures. On both the outdoor coil and the indoor coil, 
solder a thermocouple onto a return bend located at or near the midpoint 
of each coil or at points not affected by vapor superheat or liquid 
subcooling. Alternatively, if the test unit is not sensitive to the 
refrigerant charge, install pressure gages to the access valves or to 
ports created from tapping into the suction and discharge lines 
according to sections 7.4.2 and 8.2.5 of ANSI/ASHRAE 37-2009. Use this 
alternative approach when testing a unit charged with a zeotropic 
refrigerant having a temperature glide in excess of 1 [deg]F at the 
specified test conditions.

                  2.10.2 Compressor Calibration Method

    Measure refrigerant pressures and temperatures to determine the 
evaporator superheat and the enthalpy of the refrigerant that enters and 
exits the indoor coil. Determine refrigerant flow rate or, when the 
superheat of the refrigerant leaving the evaporator is less than 5 
[deg]F, total capacity from separate calibration tests conducted under 
identical operating conditions. When using this method, install 
instrumentation and measure refrigerant properties according to section 
7.4.2 and 8.2.5 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3). If removing the refrigerant before applying refrigerant 
lines and subsequently recharging, use the steps in 7.4.2 of ANSI/ASHRAE 
37-2009 in addition to the methods of section 2.2.5 of this appendix to 
confirm the refrigerant charge. Use refrigerant temperature and pressure 
measuring instruments that meet the specifications given in sections 
5.1.1 and 5.2 of ANSI/ASHRAE 37-2009.

                   2.10.3 Refrigerant Enthalpy Method

    For this method, calculate space conditioning capacity by 
determining the refrigerant enthalpy change for the indoor coil and 
directly measuring the refrigerant flow rate. Use section 7.5.2 of ANSI/
ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3) for the 
requirements for this method, including the additional instrumentation 
requirements, and information on placing the flow meter and a sight 
glass. Use refrigerant temperature, pressure, and flow measuring 
instruments that meet the specifications given in sections 5.1.1, 5.2, 
and 5.5.1 of ANSI/ASHRAE 37-2009. Refrigerant flow measurement 
device(s), if used, must be either elevated at least two feet from the 
test chamber floor or placed upon insulating material having a total 
thermal resistance of at least R-12 and extending at least one foot 
laterally beyond each side of the device(s)' exposed surfaces.

            2.11 Measurement of Test Room Ambient Conditions

    Follow instructions for setting up air sampling device and 
aspirating psychrometer as


[[Page 480]]

described in section 2.14 of this appendix, unless otherwise instructed 
in this section.
    a. If using a test set-up where air is ducted directly from the 
conditioning apparatus to the indoor coil inlet (see Figure 2, Loop Air-
Enthalpy Test Method Arrangement, of ANSI/ASHRAE 37-2009 (incorporated 
by reference, see Sec. 430.3)), add instrumentation to permit 
measurement of the indoor test room dry-bulb temperature.
    b. On the outdoor side, use one of the following two approaches, 
except that approach (1) is required for all evaporatively-cooled units 
and units that transfer condensate to the outdoor unit for evaporation 
using condenser heat.
    (1) Use sampling tree air collection on all air-inlet surfaces of 
the outdoor unit.
    (2) Use sampling tree air collection on one or more faces of the 
outdoor unit and demonstrate air temperature uniformity as follows. 
Install a grid of evenly-distributed thermocouples on each air-
permitting face on the inlet of the outdoor unit. Install the 
thermocouples on the air sampling device, locate them individually or 
attach them to a wire structure. If not installed on the air sampling 
device, install the thermocouple grid 6 to 24 inches from the unit. The 
thermocouples shall be evenly spaced across the coil inlet surface and 
be installed to avoid sampling of discharge air or blockage of air 
recirculation. The grid of thermocouples must provide at least 16 
measuring points per face or one measurement per square foot of inlet 
face area, whichever is less. This grid must be constructed and used as 
per section 5.3 of ANSI/ASHRAE 41.1-2013 (incorporated by reference, see 
Sec. 430.3). The maximum difference between the average temperatures 
measured during the test period of any two pairs of these individual 
thermocouples located at any of the faces of the inlet of the outdoor 
unit, must not exceed 2.0 [deg]F, otherwise approach (1) must be used.
    The air sampling devices shall be located at the geometric center of 
each side; the branches may be oriented either parallel or perpendicular 
to the longer edges of the air inlet area. The air sampling devices in 
the outdoor air inlet location shall be sized such that they cover at 
least 75% of the face area of the side of the coil that they are 
measuring.
    Air distribution at the test facility point of supply to the unit 
shall be reviewed and may require remediation prior to the beginning of 
testing. Mixing fans can be used to ensure adequate air distribution in 
the test room. If used, mixing fans shall be oriented such that they are 
pointed away from the air intake so that the mixing fan exhaust does not 
affect the outdoor coil air volume rate. Particular attention should be 
given to prevent the mixing fans from affecting (enhancing or limiting) 
recirculation of condenser fan exhaust air back through the unit. Any 
fan used to enhance test room air mixing shall not cause air velocities 
in the vicinity of the test unit to exceed 500 feet per minute.
    The air sampling device may be larger than the face area of the side 
being measured, however care shall be taken to prevent discharge air 
from being sampled. If an air sampling device dimension extends beyond 
the inlet area of the unit, holes shall be blocked in the air sampling 
device to prevent sampling of discharge air. Holes can be blocked to 
reduce the region of coverage of the intake holes both in the direction 
of the trunk axis or perpendicular to the trunk axis. For intake hole 
region reduction in the direction of the trunk axis, block holes of one 
or more adjacent pairs of branches (the branches of a pair connect 
opposite each other at the same trunk location) at either the outlet end 
or the closed end of the trunk. For intake hole region reduction 
perpendicular to the trunk axis, block off the same number of holes on 
each branch on both sides of the trunk.
    A maximum of four (4) air sampling devices shall be connected to 
each aspirating psychrometer. In order to proportionately divide the 
flow stream for multiple air sampling devices for a given aspirating 
psychrometer, the tubing or conduit conveying sampled air to the 
psychrometer shall be of equivalent lengths for each air sampling 
device. Preferentially, the air sampling device should be hard connected 
to the aspirating psychrometer, but if space constraints do not allow 
this, the assembly shall have a means of allowing a flexible tube to 
connect the air sampling device to the aspirating psychrometer. The 
tubing or conduit shall be insulated and routed to prevent heat transfer 
to the air stream. Any surface of the air conveying tubing in contact 
with surrounding air at a different temperature than the sampled air 
shall be insulated with thermal insulation with a nominal thermal 
resistance (R-value) of at least 19 hr [middot] ft\2\ [middot] [deg]F/
Btu. Alternatively the conduit may have lower thermal resistance if 
additional sensor(s) are used to measure dry bulb temperature at the 
outlet of each air sampling device. No part of the air sampling device 
or the tubing conducting the sampled air to the sensors shall be within 
two inches of the test chamber floor.
    Pairs of measurements (e.g., dry bulb temperature and wet bulb 
temperature) used to determine water vapor content of sampled air shall 
be measured in the same location.

                 2.12 Measurement of Indoor Blower Speed

    When required, measure fan speed using a revolution counter, 
tachometer, or stroboscope that gives readings accurate to within 1.0 percent.

[[Page 481]]

                 2.13 Measurement of Barometric Pressure

    Determine the average barometric pressure during each test. Use an 
instrument that meets the requirements specified in section 5.2 of ANSI/
ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3).

    2.14 Air Sampling Device and Aspirating Psycrhometer Requirements

    Air temperature measurements shall be made in accordance with ANSI/
ASHRAE 41.1-2013, unless otherwise instructed in this section.

                 2.14.1 Air Sampling Device Requirements

    The air sampling device is intended to draw in a sample of the air 
at the critical locations of a unit under test. It shall be constructed 
of stainless steel, plastic or other suitable, durable materials. It 
shall have a main flow trunk tube with a series of branch tubes 
connected to the trunk tube. Holes shall be on the side of the sampler 
facing the upstream direction of the air source. Other sizes and 
rectangular shapes can be used, and shall be scaled accordingly with the 
following guidelines:
    (1) Minimum hole density of 6 holes per square foot of area to be 
sampled
    (2) Sampler branch tube pitch (spacing) of 6  
3 in
    (3) Manifold trunk to branch diameter ratio having a minimum of 3:1 
ratio
    (4) Hole pitch (spacing) shall be equally distributed over the 
branch (\1/2\ pitch from the closed end to the nearest hole)
    (5) Maximum individual hole to branch diameter ratio of 1:2 (1:3 
preferred)
    The minimum average velocity through the air sampling device holes 
shall be 2.5 ft/s as determined by evaluating the sum of the open area 
of the holes as compared to the flow area in the aspirating 
psychrometer.

                     2.14.2 Aspirating Psychrometer

    The psychrometer consists of a flow section and a fan to draw air 
through the flow section and measures an average value of the sampled 
air stream. At a minimum, the flow section shall have a means for 
measuring the dry bulb temperature (typically, a resistance temperature 
device (RTD) and a means for measuring the humidity (RTD with wetted 
sock, chilled mirror hygrometer, or relative humidity sensor). The 
aspirating psychrometer shall include a fan that either can be adjusted 
manually or automatically to maintain required velocity across the 
sensors.
    The psychrometer shall be made from suitable material which may be 
plastic (such as polycarbonate), aluminum or other metallic materials. 
All psychrometers for a given system being tested, shall be constructed 
of the same material. Psychrometers shall be designed such that radiant 
heat from the motor (for driving the fan that draws sampled air through 
the psychrometer) does not affect sensor measurements. For aspirating 
psychrometers, velocity across the wet bulb sensor shall be 1000  200 ft/min. For all other psychrometers, velocity shall 
be as specified by the sensor manufacturer.

                          3. Testing Procedures

                        3.1 General Requirements

    If, during the testing process, an equipment set-up adjustment is 
made that would have altered the performance of the unit during any 
already completed test, then repeat all tests affected by the 
adjustment. For cyclic tests, instead of maintaining an air volume rate, 
for each airflow nozzle, maintain the static pressure difference or 
velocity pressure during an ON period at the same pressure difference or 
velocity pressure as measured during the steady-state test conducted at 
the same test conditions.
    Use the testing procedures in this section to collect the data used 
for calculating
    (1) Performance metrics for central air conditioners and heat pumps 
during the cooling season;
    (2) Performance metrics for heat pumps during the heating season; 
and
    (3) Power consumption metric(s) for central air conditioners and 
heat pumps during the off mode season(s).

                3.1.1 Primary and Secondary Test Methods

    For all tests, use the indoor air enthalpy method test apparatus to 
determine the unit's space conditioning capacity. The procedure and data 
collected, however, differ slightly depending upon whether the test is a 
steady-state test, a cyclic test, or a frost accumulation test. The 
following sections described these differences. For the full-capacity 
cooling-mode test and (for a heat pump) the full-capacity heating-mode 
test, use one of the acceptable secondary methods specified in section 
2.10 of this appendix to determine indoor space conditioning capacity. 
Calculate this secondary check of capacity according to section 3.11 of 
this appendix. The two capacity measurements must agree to within 6 
percent to constitute a valid test. For this capacity comparison, use 
the Indoor Air Enthalpy Method capacity that is calculated in section 
7.3 of ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3) 
(and, if testing a coil-only system, compare capacities before making 
the after-test fan heat adjustments described in section 3.3, 3.4, 3.7, 
and 3.10 of this appendix). However, include the appropriate section 3.3 
to 3.5 and 3.7 to 3.10 fan heat adjustments within the indoor air 
enthalpy method capacities used for the section 4 seasonal calculations 
of this appendix.

[[Page 482]]

             3.1.2 Manufacturer-Provided Equipment Overrides

    Where needed, the manufacturer must provide a means for overriding 
the controls of the test unit so that the compressor(s) operates at the 
specified speed or capacity and the indoor blower operates at the 
specified speed or delivers the specified air volume rate.

                 3.1.3 Airflow Through the Outdoor Coil

    For all tests, meet the requirements given in section 6.1.3.4 of 
AHRI 210/240-2008 (incorporated by reference, see Sec. 430.3) when 
obtaining the airflow through the outdoor coil.

                          3.1.3.1 Double-Ducted

    For products intended to be installed with the outdoor airflow 
ducted, the unit shall be installed with outdoor coil ductwork installed 
per manufacturer installation instructions and shall operate between 
0.10 and 0.15 in H2O external static pressure. External 
static pressure measurements shall be made in accordance with ANSI/
ASHRAE 37-2009 section 6.4 and 6.5.

                  3.1.4 Airflow Through the Indoor Coil

    Airflow setting(s) shall be determined before testing begins. Unless 
otherwise specified within this or its subsections, no changes shall be 
made to the airflow setting(s) after initiation of testing.

                3.1.4.1 Cooling Full-Load Air Volume Rate

      3.1.4.1.1. Cooling Full-Load Air Volume Rate for Ducted Units

    Identify the certified cooling full-load air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified Cooling full-load air volume rate, use a value equal to the 
certified cooling capacity of the unit times 400 scfm per 12,000 Btu/h. 
If there are no instructions for setting fan speed or controls, use the 
as-shipped settings. Use the following procedure to confirm and, if 
necessary, adjust the Cooling full-load air volume rate and the fan 
speed or control settings to meet each test procedure requirement:
    a. For all ducted blower coil systems, except those having a 
constant-air-volume-rate indoor blower:
    Step (1) Operate the unit under conditions specified for the A (for 
single-stage units) or A2 test using the certified fan speed 
or controls settings, and adjust the exhaust fan of the airflow 
measuring apparatus to achieve the certified Cooling full-load air 
volume rate;
    Step (2) Measure the external static pressure;
    Step (3) If this external static pressure is equal to or greater 
than the applicable minimum external static pressure cited in Table 4, 
the pressure requirement is satisfied; proceed to step 7 of this 
section. If this external static pressure is not equal to or greater 
than the applicable minimum external static pressure cited in Table 4, 
proceed to step 4 of this section;
    Step (4) Increase the external static pressure by adjusting the 
exhaust fan of the airflow measuring apparatus until either
    (i) The applicable Table 4 minimum is equaled or
    (ii) The measured air volume rate equals 90 percent or less of the 
Cooling full-load air volume rate, whichever occurs first;
    Step (5) If the conditions of step 4 (i) of this section occur 
first, the pressure requirement is satisfied; proceed to step 7 of this 
section. If the conditions of step 4 (ii) of this section occur first, 
proceed to step 6 of this section;
    Step (6) Make an incremental change to the setup of the indoor 
blower (e.g., next highest fan motor pin setting, next highest fan motor 
speed) and repeat the evaluation process beginning above, at step 1 of 
this section. If the indoor blower setup cannot be further changed, 
increase the external static pressure by adjusting the exhaust fan of 
the airflow measuring apparatus until the applicable Table 4 minimum is 
equaled; proceed to step 7 of this section;
    Step (7) The airflow constraints have been satisfied. Use the 
measured air volume rate as the Cooling full-load air volume rate. Use 
the final fan speed or control settings for all tests that use the 
Cooling full-load air volume rate.
    b. For ducted blower coil systems with a constant-air-volume-rate 
indoor blower. For all tests that specify the Cooling full-load air 
volume rate, obtain an external static pressure as close to (but not 
less than) the applicable Table 4 value that does not cause automatic 
shutdown of the indoor blower or air volume rate variation 
QVar, defined as follows, greater than 10 percent.
[GRAPHIC] [TIFF OMITTED] TR05JA17.008



[[Page 483]]


where:

Qmax = maximum measured airflow value
Qmin = minimum measured airflow value
QVar = airflow variance, percent

    Additional test steps as described in section 3.3.(e) of this 
appendix are required if the measured external static pressure exceeds 
the target value by more than 0.03 inches of water.
    c. For coil-only indoor units. For the A or A2 Test, 
(exclusively), the pressure drop across the indoor coil assembly must 
not exceed 0.30 inches of water. If this pressure drop is exceeded, 
reduce the air volume rate until the measured pressure drop equals the 
specified maximum. Use this reduced air volume rate for all tests that 
require the Cooling full-load air volume rate.

\4\ See section 1.2 of this appendix, Definitions, to determine if the
  equipment qualifies as a small-duct, high-velocity system.
\5\ If a closed-loop, air-enthalpy test apparatus is used on the indoor
  side, limit the resistance to airflow on the inlet side of the blower
  coil indoor unit to a maximum value of 0.1 inch of water. Impose the
  balance of the airflow resistance on the outlet side of the indoor
  blower.

    d. For ducted systems having multiple indoor blowers within a single 
indoor section, obtain the full-load air volume rate with all indoor 
blowers operating unless prevented by the controls of the unit. In such 
cases, turn on the maximum number of indoor blowers permitted by the 
unit's controls. Where more than one option exists for meeting this 
``on'' indoor blower requirement, which indoor blower(s) are turned on 
must match that specified in the certification report. Conduct section 
3.1.4.1.1 setup steps for each indoor blower separately. If two or more 
indoor blowers are connected to a common duct as per section 2.4.1 of 
this appendix, temporarily divert their air volume to the test room when 
confirming or adjusting the setup configuration of individual indoor 
blowers. The allocation of the system's full-load air volume rate 
assigned to each ``on'' indoor blower must match that specified by the 
manufacturer in the certification report.

    3.1.4.1.2. Cooling Full-Load Air Volume Rate for Non-Ducted Units

    For non-ducted units, the Cooling full-load air volume rate is the 
air volume rate that results during each test when the unit is operated 
at an external static pressure of zero inches of water.

                 3.1.4.2 Cooling Minimum Air Volume Rate

    Identify the certified cooling minimum air volume rate and certified 
instructions for setting fan speed or controls. If there is no certified 
cooling minimum air volume rate, use the final indoor blower control 
settings as determined when setting the cooling full-load air volume 
rate, and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling full load air volume obtained in 
section 3.1.4.1 of this appendix. Otherwise, calculate the target 
external static pressure and follow instructions a, b, c, d, or e below. 
The target external static pressure, [Delta]Pst_i, for any 
test ``i'' with a specified air volume rate not equal to the Cooling 
full-load air volume rate is determined as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.009

where:

[Delta]Pst_i = target minimum external static pressure for 
          test i;
[Delta]Pst_full = minimum external static pressure for test A 
          or A2 (Table 4);
Qi = air volume rate for test i; and
Qfull = Cooling full-load air volume rate as measured after 
          setting and/or adjustment as described in section 3.1.4.1.1 of 
          this appendix.

    a. For a ducted blower coil system without a constant-air-volume 
indoor blower, adjust for external static pressure as follows:
    Step (1) Operate the unit under conditions specified for the B1 test 
using the certified fan speed or controls settings, and adjust the 
exhaust fan of the airflow measuring apparatus to achieve the certified 
cooling minimum air volume rate;

[[Page 484]]

    Step (2) Measure the external static pressure;
    Step (3) If this pressure is equal to or greater than the minimum 
external static pressure computed above, the pressure requirement is 
satisfied; proceed to step 7 of this section. If this pressure is not 
equal to or greater than the minimum external static pressure computed 
above, proceed to step 4 of this section;
    Step (4) Increase the external static pressure by adjusting the 
exhaust fan of the airflow measuring apparatus until either
    (i) The pressure is equal to the minimum external static pressure 
computed above or
    (ii) The measured air volume rate equals 90 percent or less of the 
cooling minimum air volume rate, whichever occurs first;
    Step (5) If the conditions of step 4 (i) of this section occur 
first, the pressure requirement is satisfied; proceed to step 7 of this 
section. If the conditions of step 4 (ii) of this section occur first, 
proceed to step 6 of this section;
    Step (6) Make an incremental change to the setup of the indoor 
blower (e.g., next highest fan motor pin setting, next highest fan motor 
speed) and repeat the evaluation process beginning above, at step 1 of 
this section. If the indoor blower setup cannot be further changed, 
increase the external static pressure by adjusting the exhaust fan of 
the airflow measuring apparatus until it equals the minimum external 
static pressure computed above; proceed to step 7 of this section;
    Step (7) The airflow constraints have been satisfied. Use the 
measured air volume rate as the cooling minimum air volume rate. Use the 
final fan speed or control settings for all tests that use the cooling 
minimum air volume rate.
    b. For ducted units with constant-air-volume indoor blowers, conduct 
all tests that specify the cooling minimum air volume rate--(i.e., the 
A1, B1, C1, F1, and 
G1 Tests)--at an external static pressure that does not cause 
an automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than the 
target minimum external static pressure. Additional test steps as 
described in section 3.3(e) of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For ducted two-capacity coil-only systems, the cooling minimum 
air volume rate is the higher of (1) the rate specified by the 
installation instructions included with the unit by the manufacturer or 
(2) 75 percent of the cooling full-load air volume rate. During the 
laboratory tests on a coil-only (fanless) system, obtain this cooling 
minimum air volume rate regardless of the pressure drop across the 
indoor coil assembly.
    d. For non-ducted units, the cooling minimum air volume rate is the 
air volume rate that results during each test when the unit operates at 
an external static pressure of zero inches of water and at the indoor 
blower setting used at low compressor capacity (two-capacity system) or 
minimum compressor speed (variable-speed system). For units having a 
single-speed compressor and a variable-speed variable-air-volume-rate 
indoor blower, use the lowest fan setting allowed for cooling.
    e. For ducted systems having multiple indoor blowers within a single 
indoor section, operate the indoor blowers such that the lowest air 
volume rate allowed by the unit's controls is obtained when operating 
the lone single-speed compressor or when operating at low compressor 
capacity while meeting the requirements of section 2.2.3.b of this 
appendix for the minimum number of blowers that must be turned off. 
Using the target external static pressure and the certified air volume 
rates, follow the procedures described in section 3.1.4.2.a of this 
appendix if the indoor blowers are not constant-air-volume indoor 
blowers or as described in section 3.1.4.2.b of this appendix if the 
indoor blowers are constant-air-volume indoor blowers. The sum of the 
individual ``on'' indoor blowers' air volume rates is the cooling 
minimum air volume rate for the system.

              3.1.4.3 Cooling Intermediate Air Volume Rate

    Identify the certified cooling intermediate air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified cooling intermediate air volume rate, use the final indoor 
blower control settings as determined when setting the cooling full load 
air volume rate, and readjust the exhaust fan of the airflow measuring 
apparatus if necessary to reset to the cooling full load air volume 
obtained in section 3.1.4.1 of this appendix. Otherwise, calculate 
target minimum external static pressure as described in section 3.1.4.2 
of this appendix, and set the air volume rate as follows.
    a. For a ducted blower coil system without a constant-air-volume 
indoor blower, adjust for external static pressure as described in 
section 3.1.4.2.a of this appendix for cooling minimum air volume rate.
    b. For a ducted blower coil system with a constant-air-volume indoor 
blower, conduct the EV Test at an external static pressure 
that does not cause an automatic shutdown of the indoor blower or air 
volume rate variation QVar, defined in section 3.1.4.1.1.b of 
this appendix, greater than 10 percent, while being as close to, but not 
less than the target minimum external static pressure. Additional test 
steps as described in section 3.3(e) of this appendix are required if 
the measured external static pressure exceeds the target value by more 
than 0.03 inches of water.

[[Page 485]]

    c. For non-ducted units, the cooling intermediate air volume rate is 
the air volume rate that results when the unit operates at an external 
static pressure of zero inches of water and at the fan speed selected by 
the controls of the unit for the EV Test conditions.

                3.1.4.4 Heating Full-Load Air Volume Rate

3.1.4.4.1. Ducted Heat Pumps Where the Heating and Cooling Full-Load Air 
                        Volume Rates Are the Same

    a. Use the Cooling full-load air volume rate as the heating full-
load air volume rate for:
    (1) Ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, and that operate at the same airflow-
control setting during both the A (or A2) and the H1 (or 
H12) Tests;
    (2) Ducted blower coil system heat pumps with constant-air-flow 
indoor blowers that provide the same air flow for the A (or 
A2) and the H1 (or H12) Tests; and
    (3) Ducted heat pumps that are tested with a coil-only indoor unit 
(except two-capacity northern heat pumps that are tested only at low 
capacity cooling--see section 3.1.4.4.2 of this appendix).
    b. For heat pumps that meet the above criteria ``1'' and ``3,'' no 
minimum requirements apply to the measured external or internal, 
respectively, static pressure. Use the final indoor blower control 
settings as determined when setting the Cooling full-load air volume 
rate, and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling full-load air volume obtained in 
section 3.1.4.1 of this appendix. For heat pumps that meet the above 
criterion ``2,'' test at an external static pressure that does not cause 
an automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than, the 
same Table 4 minimum external static pressure as was specified for the A 
(or A2) cooling mode test. Additional test steps as described 
in section 3.9.1(c) of this appendix are required if the measured 
external static pressure exceeds the target value by more than 0.03 
inches of water.

3.1.4.4.2. Ducted Heat Pumps Where the Heating and Cooling Full-Load Air 
 Volume Rates Are Different Due to Changes in Indoor Blower Operation, 
              i.e. Speed Adjustment by the System Controls

    Identify the certified heating full-load air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified heating full-load air volume rate, use the final indoor blower 
control settings as determined when setting the cooling full-load air 
volume rate, and readjust the exhaust fan of the airflow measuring 
apparatus if necessary to reset to the cooling full load air volume 
obtained in section 3.1.4.1 of this appendix. Otherwise, calculate 
target minimum external static pressure as described in section 3.1.4.2 
of this appendix and set the air volume rate as follows.
    a. For ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, adjust for external static pressure 
as described in section 3.1.4.2.a of this appendix for cooling minimum 
air volume rate.
    b. For ducted heat pumps tested with constant-air-volume indoor 
blowers installed, conduct all tests that specify the heating full-load 
air volume rate at an external static pressure that does not cause an 
automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than the 
target minimum external static pressure. Additional test steps as 
described in section 3.9.1(c) of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. When testing ducted, two-capacity blower coil system northern 
heat pumps (see section 1.2 of this appendix, Definitions), use the 
appropriate approach of the above two cases. For coil-only system 
northern heat pumps, the heating full-load air volume rate is the lesser 
of the rate specified by the manufacturer in the installation 
instructions included with the unit or 133 percent of the cooling full-
load air volume rate. For this latter case, obtain the heating full-load 
air volume rate regardless of the pressure drop across the indoor coil 
assembly.
    d. For ducted systems having multiple indoor blowers within a single 
indoor section, obtain the heating full-load air volume rate using the 
same ``on'' indoor blowers as used for the Cooling full-load air volume 
rate. Using the target external static pressure and the certified air 
volume rates, follow the procedures as described in section 3. 1.4. 
4.2.a of this appendix if the indoor blowers are not constant-air-volume 
indoor blowers or as described in section 3. 1.4.4 .2.b of this appendix 
if the indoor blowers are constant-air-volume indoor blowers. The sum of 
the individual ``on'' indoor blowers' air volume rates is the heating 
full load air volume rate for the system.I713.1.4.4.3. Ducted Heating-
Only Heat Pumps
    Identify the certified heating full-load air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified heating full-load air volume rate, use a value equal to the 
certified heating capacity of the unit times 400 scfm per 12,000 Btu/h. 
If there are no instructions for setting fan speed or controls, use the 
as-shipped settings.

    a. For all ducted heating-only blower coil system heat pumps, except 
those having a constant-air-volume-rate indoor blower. Conduct the 
following steps only during the first test, the H1 or H12 
Test:
    Step (1) Adjust the exhaust fan of the airflow measuring apparatus 
to achieve the certified heating full-load air volume rate.
    Step (2) Measure the external static pressure.
    Step (3) If this pressure is equal to or greater than the Table 4 
minimum external static pressure that applies given the heating-only 
heat pump's rated heating capacity, the pressure requirement is 
satisfied; proceed to step 7 of this section. If this pressure is not 
equal to or greater than the applicable Table 4 minimum external static 
pressure, proceed to step 4 of this section;
    Step (4) Increase the external static pressure by adjusting the 
exhaust fan of the airflow measuring apparatus until either (i) the 
pressure is equal to the applicable Table 4 minimum external static 
pressure or (ii) the measured air volume rate equals 90 percent or less 
of the heating full-load air volume rate, whichever occurs first;
    Step (5) If the conditions of step 4(i) of this section occur first, 
the pressure requirement is satisfied; proceed to step 7 of this 
section. If the conditions of step 4(ii) of this section occur first, 
proceed to step 6 of this section;
    Step (6) Make an incremental change to the setup of the indoor 
blower (e.g., next highest fan motor pin setting, next highest fan motor 
speed) and repeat the evaluation process beginning above, at step 1 of 
this section. If the indoor blower setup cannot be further changed, 
increase the external static pressure by adjusting the exhaust fan of 
the airflow measuring apparatus until it equals the applicable Table 4 
minimum external static pressure; proceed to step 7 of this section;
    Step (7) The airflow constraints have been satisfied. Use the 
measured air volume rate as the heating full-load air volume rate. Use 
the final fan speed or control settings for all tests that use the 
heating full-load air volume rate.
    b. For ducted heating-only blower coil system heat pumps having a 
constant-air-volume-rate indoor blower. For all tests that specify the 
heating full-load air volume rate, obtain an external static pressure 
that does not cause an automatic shutdown of the indoor blower or air 
volume rate variation QVar, defined in section 3.1.4.1.1.b of 
this appendix, greater than 10 percent, while being as close to, but not 
less than, the applicable Table 4 minimum. Additional test steps as 
described in section 3.9.1(c) of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For ducted heating-only coil-only system heat pumps in the H1 or 
H12 Test, (exclusively), the pressure drop across the indoor 
coil assembly must not exceed 0.30 inches of water. If this pressure 
drop is exceeded, reduce the air volume rate until the measured pressure 
drop equals the specified maximum. Use this reduced air volume rate for 
all tests that require the heating full-load air volume rate.

3.1.4.4.4. Non-Ducted Heat Pumps, Including Non-Ducted Heating-Only Heat 
                                  Pumps

    For non-ducted heat pumps, the heating full-load air volume rate is 
the air volume rate that results during each test when the unit operates 
at an external static pressure of zero inches of water.

                 3.1.4.5 Heating Minimum Air Volume Rate

 3.1.4.5.1. Ducted Heat Pumps Where the Heating and Cooling Minimum Air 
                        Volume Rates Are the Same

    a. Use the cooling minimum air volume rate as the heating minimum 
air volume rate for:
    (1) Ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, and that operate at the same airflow-
control setting during both the A1 and the H11 
tests;
    (2) Ducted blower coil system heat pumps with constant-air-flow 
indoor blowers installed that provide the same air flow for the 
A1 and the H11 Tests; and
    (3) Ducted coil-only system heat pumps.
    b. For heat pumps that meet the above criteria ``1'' and ``3,'' no 
minimum requirements apply to the measured external or internal, 
respectively, static pressure. Use the final indoor blower control 
settings as determined when setting the cooling minimum air volume rate, 
and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling minimum air volume rate obtained in 
section 3.1.4.2 of this appendix. For heat pumps that meet the above 
criterion ``2,'' test at an external static pressure that does not cause 
an automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than, the 
same target minimum external static pressure as was specified for the 
A1 cooling mode test. Additional test steps as described in 
section 3.9.1(c) of this appendix are required if the measured external 
static pressure exceeds the target value by more than 0.03 inches of 
water.

[[Page 487]]

 3.1.4.5.2. Ducted Heat Pumps Where the Heating and Cooling Minimum Air 
 Volume Rates Are Different Due to Changes in Indoor Blower Operation, 
              i.e. Speed Adjustment by the System Controls

    Identify the certified heating minimum air volume rate and certified 
instructions for setting fan speed or controls. If there is no certified 
heating minimum air volume rate, use the final indoor blower control 
settings as determined when setting the cooling minimum air volume rate, 
and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling minimum air volume obtained in section 
3.1.4.2 of this appendix. Otherwise, calculate the target minimum 
external static pressure as described in section 3.1.4.2 of this 
appendix.
    a. For ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, adjust for external static pressure 
as described in section 3.1.4.2.a of this appendix for cooling minimum 
air volume rate.
    b. For ducted heat pumps tested with constant-air-volume indoor 
blowers installed, conduct all tests that specify the heating minimum 
air volume rate--(i.e., the H01, H11, 
H21, and H31 Tests)--at an external static 
pressure that does not cause an automatic shutdown of the indoor blower 
while being as close to, but not less than the air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than the 
target minimum external static pressure. Additional test steps as 
described in section 3.9.1.c of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For ducted two-capacity blower coil system northern heat pumps, 
use the appropriate approach of the above two cases.
    d. For ducted two-capacity coil-only system heat pumps, use the 
cooling minimum air volume rate as the heating minimum air volume rate. 
For ducted two-capacity coil-only system northern heat pumps, use the 
cooling full-load air volume rate as the heating minimum air volume 
rate. For ducted two-capacity heating-only coil-only system heat pumps, 
the heating minimum air volume rate is the higher of the rate specified 
by the manufacturer in the test setup instructions included with the 
unit or 75 percent of the heating full-load air volume rate. During the 
laboratory tests on a coil-only system, obtain the heating minimum air 
volume rate without regard to the pressure drop across the indoor coil 
assembly.
    e. For non-ducted heat pumps, the heating minimum air volume rate is 
the air volume rate that results during each test when the unit operates 
at an external static pressure of zero inches of water and at the indoor 
blower setting used at low compressor capacity (two-capacity system) or 
minimum compressor speed (variable-speed system). For units having a 
single-speed compressor and a variable-speed, variable-air-volume-rate 
indoor blower, use the lowest fan setting allowed for heating.
    f. For ducted systems with multiple indoor blowers within a single 
indoor section, obtain the heating minimum air volume rate using the 
same ``on'' indoor blowers as used for the cooling minimum air volume 
rate. Using the target external static pressure and the certified air 
volume rates, follow the procedures as described in section 3.1.4.5.2.a 
of this appendix if the indoor blowers are not constant-air-volume 
indoor blowers or as described in section 3.1.4.5.2.b of this appendix 
if the indoor blowers are constant-air-volume indoor blowers. The sum of 
the individual ``on'' indoor blowers' air volume rates is the heating 
full-load air volume rate for the system.

              3.1.4.6 Heating Intermediate Air Volume Rate

    Identify the certified heating intermediate air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified heating intermediate air volume rate, use the final indoor 
blower control settings as determined when setting the heating full-load 
air volume rate, and readjust the exhaust fan of the airflow measuring 
apparatus if necessary to reset to the cooling full load air volume 
obtained in section 3.1.4.2 of this appendix. Calculate the target 
minimum external static pressure as described in section 3.1.4.2 of this 
appendix.
    a. For ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, adjust for external static pressure 
as described in section 3.1.4.2.a of this appendix for cooling minimum 
air volume rate.
    b. For ducted heat pumps tested with constant-air-volume indoor 
blowers installed, conduct the H2V Test at an external static 
pressure that does not cause an automatic shutdown of the indoor blower 
or air volume rate variation QVar, defined in section 
3.1.4.1.1.b of this appendix, greater than 10 percent, while being as 
close to, but not less than the target minimum external static pressure. 
Additional test steps as described in section 3.9.1(c) of this appendix 
are required if the measured external static pressure exceeds the target 
value by more than 0.03 inches of water.
    c. For non-ducted heat pumps, the heating intermediate air volume 
rate is the air volume rate that results when the heat pump operates at 
an external static pressure of zero inches of water and at the fan speed 
selected by the controls of the unit for the H2V Test 
conditions.

[[Page 488]]

                 3.1.4.7 Heating Nominal Air Volume Rate

    The manufacturer must specify the heating nominal air volume rate 
and the instructions for setting fan speed or controls. Calculate target 
minimum external static pressure as described in section 3.1.4.2 of this 
appendix. Make adjustments as described in section 3.1.4.6 of this 
appendix for heating intermediate air volume rate so that the target 
minimum external static pressure is met or exceeded.

 3.1.5 Indoor Test Room Requirement When the Air Surrounding the Indoor 
Unit Is Not Supplied From the Same Source as the Air Entering the Indoor 
                                  Unit

    If using a test set-up where air is ducted directly from the air 
reconditioning apparatus to the indoor coil inlet (see Figure 2, Loop 
Air-Enthalpy Test Method Arrangement, of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3)), maintain the dry bulb 
temperature within the test room within 5.0 [deg]F 
of the applicable sections 3.2 and 3.6 dry bulb temperature test 
condition for the air entering the indoor unit. Dew point shall be 
within 2 [deg]F of the required inlet conditions.

                   3.1.6 Air Volume Rate Calculations

    For all steady-state tests and for frost accumulation (H2, 
H21, H22, H2V) tests, calculate the air 
volume rate through the indoor coil as specified in sections 7.7.2.1 and 
7.7.2.2 of ANSI/ASHRAE 37-2009. When using the outdoor air enthalpy 
method, follow sections 7.7.2.1 and 7.7.2.2 of ANSI/ASHRAE 37-2009 to 
calculate the air volume rate through the outdoor coil. To express air 
volume rates in terms of standard air, use:
[GRAPHIC] [TIFF OMITTED] TR05JA17.010

Where:

Vis = air volume rate of standard (dry) air, (ft\3\/
          min)da
Vimx = air volume rate of the air-water vapor mixture, 
          (ft\3\/min)mx
vn[min] = specific volume of air-water vapor mixture at the 
          nozzle, ft\3\ per lbm of the air-water vapor mixture
Wn = humidity ratio at the nozzle, lbm of water vapor per lbm 
          of dry air
0.075 = the density associated with standard (dry) air, (lbm/ft\3\)
vn = specific volume of the dry air portion of the mixture 
          evaluated at the dry-bulb temperature, vapor content, and 
          barometric pressure existing at the nozzle, ft\3\ per lbm of 
          dry air.
    Note: In the first printing of ANSI/ASHRAE 37-2009, the second IP 
equation for Qmi should read
[GRAPHIC] [TIFF OMITTED] TR05JA17.011

                           3.1.7 Test Sequence

    Before making test measurements used to calculate performance, 
operate the equipment for the ``break-in'' period specified in the 
certification report, which may not exceed 20 hours. Each compressor of 
the unit must undergo this ``break-in'' period. When testing a ducted 
unit (except if a heating-only heat pump), conduct the A or 
A2 Test first to establish the cooling full-load air volume 
rate. For ducted heat pumps where the heating and cooling full-load air 
volume rates are different, make the first heating mode test one that 
requires the heating full-load air volume rate. For ducted heating-only 
heat pumps, conduct the H1 or H12 Test first to establish the 
heating full-load air volume rate. When conducting a cyclic test, always 
conduct it immediately after the steady-state test that requires the 
same test conditions. For variable-speed systems, the first test using 
the cooling minimum air volume rate should precede the EV 
Test, and the first test using the heating minimum air volume rate must 
precede the H2V Test. The test laboratory makes all other 
decisions on the test sequence.

   3.1.8 Requirement for the Air Temperature Distribution Leaving the 
                               Indoor Coil

    For at least the first cooling mode test and the first heating mode 
test, monitor the temperature distribution of the air leaving the indoor 
coil using the grid of individual sensors described in sections 2.5 and 
2.5.4 of this appendix. For the 30-minute data collection interval used 
to determine capacity, the maximum spread among the outlet dry bulb

[[Page 489]]

temperatures from any data sampling must not exceed 1.5 [deg]F. Install 
the mixing devices described in section 2.5.4.2 of this appendix to 
minimize the temperature spread.

  3.1.9 Requirement for the Air Temperature Distribution Entering the 
                              Outdoor Coil

    Monitor the temperatures of the air entering the outdoor coil using 
air sampling devices and/or temperature sensor grids, maintaining the 
required tolerances, if applicable, as described in section 2.11 of this 
appendix.

         3.1.10 Control of Auxiliary Resistive Heating Elements

    Except as noted, disable heat pump resistance elements used for 
heating indoor air at all times, including during defrost cycles and if 
they are normally regulated by a heat comfort controller. For heat pumps 
equipped with a heat comfort controller, enable the heat pump resistance 
elements only during the below-described, short test. For single-speed 
heat pumps covered under section 3.6.1 of this appendix, the short test 
follows the H1 or, if conducted, the H1C Test. For two-capacity heat 
pumps and heat pumps covered under section 3.6.2 of this appendix, the 
short test follows the H12 Test. Set the heat comfort 
controller to provide the maximum supply air temperature. With the heat 
pump operating and while maintaining the heating full-load air volume 
rate, measure the temperature of the air leaving the indoor-side 
beginning 5 minutes after activating the heat comfort controller. Sample 
the outlet dry-bulb temperature at regular intervals that span 5 minutes 
or less. Collect data for 10 minutes, obtaining at least 3 samples. 
Calculate the average outlet temperature over the 10-minute interval, 
TCC.

3.2 Cooling Mode Tests for Different Types of Air Conditioners and Heat 
                                  Pumps

  3.2.1 Tests for a System Having a Single-Speed Compressor and Fixed 
                         Cooling Air Volume Rate

    This set of tests is for single-speed-compressor units that do not 
have a cooling minimum air volume rate or a cooling intermediate air 
volume rate that is different than the cooling full load air volume 
rate. Conduct two steady-state wet coil tests, the A and B Tests. Use 
the two optional dry-coil tests, the steady-state C Test and the cyclic 
D Test, to determine the cooling mode cyclic degradation coefficient, 
CD\c\. If the two optional tests are conducted but yield a 
tested CD\c\ that exceeds the default CD\c\ or if 
the two optional tests are not conducted, assign CD\c\ the 
default value of 0.25 (for outdoor units with no match) or 0.20 (for all 
other systems). Table 5 specifies test conditions for these four tests.

  recommended that an indoor wet-bulb temperature of 57 [deg]F or less be used.)
\4\ Maintain the airflow nozzles static pressure difference or velocity pressure during the ON period at the
  same pressure difference or velocity pressure as measured during the C Test.

3.2.2 Tests for a Unit Having a Single-Speed Compressor Where the Indoor 
  Section Uses a Single Variable-Speed Variable-Air-Volume Rate Indoor 
                    Blower or Multiple Indoor Blowers

   3.2.2.1 Indoor Blower Capacity Modulation That Correlates With the 
 Outdoor Dry Bulb Temperature or Systems With a Single Indoor Coil but 
                         Multiple Indoor Blowers

    Conduct four steady-state wet coil tests: The A2, 
A1, B2, and B1 tests. Use the two 
optional dry-coil tests, the steady-state C1 test and the 
cyclic D1 test, to determine the cooling mode cyclic 
degradation coefficient, CD\c\. If the two optional tests are 
conducted but yield a tested CDc that exceeds the default 
CDc or if the two optional tests are not conducted, assign 
CDc the default value of 0.20.

    3.2.2.2 Indoor Blower Capacity Modulation Based on Adjusting the 
             Sensible to Total (S/T) Cooling Capacity Ratio

    The testing requirements are the same as specified in section 3.2.1 
of this appendix and Table 5. Use a cooling full-load air volume rate 
that represents a normal installation. If

ating in the same S/T capacity control mode as used for the B Test.

3.2.3 Tests for a Unit Having a Two-Capacity Compressor (See Section 1.2 
                     of This Appendix, Definitions)

    a. Conduct four steady-state wet coil tests: the A2, 
B2, B1, and F1 Tests. Use the two 
optional dry-coil tests, the steady-state C1 Test and the 
cyclic D1 Test, to determine the cooling-mode cyclic-
degradation coefficient, CD\c\. If the two optional tests are 
conducted but yield a tested CDc that exceeds the default 
CDc or if the two optional tests are not conducted, assign 
CDc the default value of 0.20. Table 6 specifies test 
conditions for these six tests.
    b. For units having a variable speed indoor blower that is modulated 
to adjust the sensible to total (S/T) cooling capacity ratio, use 
cooling full-load and cooling minimum air volume rates that represent a 
normal installation. Additionally, if conducting the dry-coil tests, 
operate the unit in the same S/T capacity control mode as used for the 
B1 Test.
    c. Test two-capacity, northern heat pumps (see section 1.2 of this 
appendix, Definitions) in the same way as a single speed heat pump with 
the unit operating exclusively at low compressor capacity (see section 
3.2.1 of this appendix and Table 5).
    d. If a two-capacity air conditioner or heat pump locks out low-
capacity operation at higher outdoor temperatures, then use the two dry-
coil tests, the steady-state C2 Test and the cyclic 
D2 Test, to determine the cooling-mode cyclic-degradation 
coefficient that only applies to on/off cycling from high capacity, 
CD\c\(k=2). If the two optional tests are conducted but yield 
a tested CD\c\ (k = 2) that exceeds the default CD\c\ (k = 2) or if the 
two optional tests are not conducted, assign CD\c\ (k = 2) the default 
value. The default CD\c\(k=2) is the same value as determined 
or assigned for the low-capacity cyclic-degradation coefficient, 
CD\c\ [or equivalently, CD\c\(k=1)].

        3.2.4 Tests for a Unit Having a Variable-Speed Compressor

    a. Conduct five steady-state wet coil tests: The A2, 
EV, B2, B1, and F1 Tests. 
Use the two optional dry-coil tests, the steady-state G1 Test 
and the cyclic I1 Test, to determine the cooling mode cyclic 
degradation coefficient, CD\c\. If the two optional tests are 
conducted but yield a tested CDc that exceeds the default 
CDc or if the two optional tests are not conducted, assign 
CDc the default value of 0.25. Table 8 specifies test 
conditions for these seven tests. The compressor shall operate at the 
same cooling full speed, measured by RPM or power input frequency (Hz), 
for both the A2 and B2 tests. The compressor shall 
operate at the same cooling minimum speed, measured by RPM or power 
input frequency (Hz), for the B1, F1, 
G1, and I1 tests. Determine the cooling 
intermediate compressor speed cited in Table 8 using:

[GRAPHIC] [TIFF OMITTED] TR05JA17.012

where a tolerance of plus 5 percent or the next higher inverter 
          frequency step from that calculated is allowed.

    b. For units that modulate the indoor blower speed to adjust the 
sensible to total (S/T) cooling capacity ratio, use cooling full-load, 
cooling intermediate, and cooling minimum air volume rates that 
represent a normal installation. Additionally, if conducting the dry-
coil tests, operate the unit in the same S/T capacity control mode as 
used for the F1 Test.
    c. For multiple-split air conditioners and heat pumps (except where 
noted), the following procedures supersede the above requirements: For 
all Table 8 tests specified for a minimum compressor speed, at least one 
indoor unit must be turned off. The manufacturer shall designate the 
particular indoor unit(s) that is turned off. The manufacturer must also 
specify the compressor speed used for the Table 8 EV Test, a 
cooling-mode intermediate compressor speed that falls within \1/4\ and 
\3/4\ of the difference between the full and minimum cooling-mode 
speeds. The manufacturer should prescribe an intermediate speed that is 
expected to yield the highest EER for the given EV Test 
conditions and bracketed compressor speed range. The manufacturer can 
designate that one or more indoor units are turned off for the 
EV Test.

 3.2.5 Cooling Mode Tests for Northern Heat Pumps With Triple-Capacity

    Test triple-capacity, northern heat pumps for the cooling mode in 
the same way as specified in section 3.2.3 of this appendix for units 
having a two-capacity compressor.

    Conduct the cooling mode tests specified in section 3.2.3 of this 
appendix.

3.3 Test Procedures for Steady-State Wet Coil Cooling Mode Tests (the A, 
                  A2, A1, B, B2, B1, EV, and F1 Tests)

    a. For the pretest interval, operate the test room reconditioning 
apparatus and the unit to be tested until maintaining equilibrium 
conditions for at least 30 minutes at the specified section 3.2 test 
conditions. Use the exhaust fan of the airflow measuring apparatus and, 
if installed, the indoor blower of the test unit to obtain and then 
maintain the indoor air volume rate and/or external static pressure 
specified for the particular test. Continuously record (see section 1.2 
of this appendix, Definitions):
    (1) The dry-bulb temperature of the air entering the indoor coil,
    (2) The water vapor content of the air entering the indoor coil,
    (3) The dry-bulb temperature of the air entering the outdoor coil, 
and
    (4) For the section 2.2.4 of this appendix cases where its control 
is required, the water vapor content of the air entering the outdoor 
coil.
    Refer to section 3.11 of this appendix for additional requirements 
that depend on the selected secondary test method.
    b. After satisfying the pretest equilibrium requirements, make the 
measurements specified in Table 3 of ANSI/ASHRAE 37-2009 for the indoor 
air enthalpy method and the user-selected secondary method. Make said 
Table 3 measurements at equal intervals that span 5 minutes or less. 
Continue data sampling until reaching a 30-minute period (e.g., seven 
consecutive 5-minute samples) where the test tolerances specified in 
Table 9 are satisfied. For those continuously recorded parameters, use 
the entire data set from the 30-minute interval to evaluate Table 9 
compliance. Determine the average electrical power consumption of the 
air conditioner or heat pump over the same 30-minute interval.
    c. Calculate indoor-side total cooling capacity and sensible cooling 
capacity as specified in sections 7.3.3.1 and 7.3.3.3 of ANSI/ASHRAE 37-
2009 (incorporated by reference, see Sec. 430.3). To calculate 
capacity, use the averages of the measurements (e.g. inlet and outlet 
dry bulb and wet bulb temperatures measured at the psychrometers) that 
are continuously recorded for the same 30-minute interval used as 
described above to evaluate compliance with test tolerances. Do not 
adjust the parameters used in calculating capacity for the permitted 
variations in test conditions. Evaluate air enthalpies based on the 
measured barometric pressure. Use the values of the specific heat of air 
given in section 7.3.3.1 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3) for calculation of the sensible cooling 
capacities. Assign the average total space cooling capacity, average 
sensible cooling capacity, and electrical power consumption over the 30-
minute data collection interval to the variables Qc\k\(T), 
Qsc\k\(T) and Ec\k\(T), respectively. For these 
three variables, replace the ``T'' with the nominal outdoor temperature 
at which the test was conducted. The superscript k is used only when 
testing multi-capacity units.
    Use the superscript k=2 to denote a test with the unit operating at 
high capacity or full speed, k=1 to denote low capacity or minimum 
speed, and k=v to denote the intermediate speed.
    d. For coil-only system tests, decrease Qc\k\(T) by
    [GRAPHIC] [TIFF OMITTED] TR05JA17.013
    

    and increase Ec\k\(T) by,

where VIs is the average measured indoor air volume rate 
          expressed in units of cubic feet per minute of standard air

    e. For air conditioners and heat pumps having a constant-air-volume-

if the average of the measured external static pressures exceeds the 
applicable sections 3.1.4 minimum (or target) external static pressure 
([Delta]Pmin) by 0.03 inches of water or more.
    (1) Measure the average power consumption of the indoor blower motor 
(Efan,1) and record the corresponding external static 
pressure ([Delta]P1) during or immediately following the 30-
minute interval used for determining capacity.
    (2) After completing the 30-minute interval and while maintaining 
the same test conditions, adjust the exhaust fan of the airflow 
measuring apparatus until the external static pressure increases to 
approximately [Delta]P1 + ([Delta]P1-
[Delta]Pmin).
    (3) After re-establishing steady readings of the fan motor power and 
external static pressure, determine average values for the indoor blower 
power (Efan,2) and the external static pressure 
([Delta]P2) by making measurements over a 5-minute interval.
    (4) Approximate the average power consumption of the indoor blower 
motor at [Delta]Pmin using linear extrapolation:

by the quantity (Efan,1-Efan,min), when expressed 
on a Btu/h basis. Decrease the total electrical power, 
Ec\k\(T), by the same fan power difference, now expressed in 
watts.

  3.4 Test Procedures for the Steady-State Dry-Coil Cooling-Mode Tests 
                      (the C, C1, C2, and G1 Tests)

    a. Except for the modifications noted in this section, conduct the 
steady-state dry coil cooling mode tests as specified in section 3.3 of 
this appendix for wet coil tests. Prior to recording data during the 
steady-state dry coil test, operate the unit at least one hour after 
achieving dry coil conditions. Drain the drain pan and plug the drain 
opening. Thereafter, the drain pan should remain completely dry.
    b. Denote the resulting total space cooling capacity and electrical 
power derived from the test as Qss,dry and 
Ess,dry. With regard to a section 3.3 deviation, do not 
adjust Qss,dry for duct losses (i.e., do not apply section 
7.3.3.3 of ANSI/ASHRAE 37-2009). In preparing for the section 3.5 cyclic 
tests of this appendix, record the average indoor-side air volume rate, 
VI, specific heat of the air, Cp,a (expressed on dry air basis), 
specific volume of the air at the nozzles, v[min]n, humidity 
ratio at the nozzles, Wn, and either pressure difference or 
velocity pressure for the flow nozzles. For units having a variable-
speed indoor blower (that provides either a constant or variable air 
volume rate) that will or may be tested during the cyclic dry coil 
cooling mode test with the indoor blower turned off (see section 3.5 of 
this appendix), include the electrical power used by the indoor blower 
motor among the recorded parameters from the 30-minute test.
    c. If the temperature sensors used to provide the primary 
measurement of the indoor-side dry bulb temperature difference during 
the steady-state dry-coil test and the subsequent cyclic dry-coil test 
are different, include measurements of the latter sensors

[[Page 494]]

among the regularly sampled data. Beginning at the start of the 30-
minute data collection period, measure and compute the indoor-side air 
dry-bulb temperature difference using both sets of instrumentation, 
[Delta]T (Set SS) and [Delta]T (Set CYC), for each equally spaced data 
sample. If using a consistent data sampling rate that is less than 1 
minute, calculate and record minutely averages for the two temperature 
differences. If using a consistent sampling rate of one minute or more, 
calculate and record the two temperature differences from each data 
sample. After having recorded the seventh (i=7) set of temperature 
differences, calculate the following ratio using the first seven sets of 
values:
[GRAPHIC] [TIFF OMITTED] TR05JA17.016

    Each time a subsequent set of temperature differences is recorded 
(if sampling more frequently than every 5 minutes), calculate 
FCD using the most recent seven sets of values. Continue 
these calculations until the 30-minute period is completed or until a 
value for FCD is calculated that falls outside the allowable 
range of 0.94-1.06. If the latter occurs, immediately suspend the test 
and identify the cause for the disparity in the two temperature 
difference measurements. Recalibration of one or both sets of 
instrumentation may be required. If all the values for FCD 
are within the allowable range, save the final value of the ratio from 
the 30-minute test as FCD*. If the temperature sensors used 
to provide the primary measurement of the indoor-side dry bulb 
temperature difference during the steady-state dry-coil test and the 
subsequent cyclic dry-coil test are the same, set FCD*= 1.

 3.5 Test Procedures for the Cyclic Dry-Coil Cooling-Mode Tests (the D, 
                          D1, D2, and I1 Tests)

    After completing the steady-state dry-coil test, remove the outdoor 
air enthalpy method test apparatus, if connected, and begin manual OFF/
ON cycling of the unit's compressor. The test set-up should otherwise be 
identical to the set-up used during the steady-state dry coil test. When 
testing heat pumps, leave the reversing valve during the compressor OFF 
cycles in the same position as used for the compressor ON cycles, unless 
automatically changed by the controls of the unit. For units having a 
variable-speed indoor blower, the manufacturer has the option of 
electing at the outset whether to conduct the cyclic test with the 
indoor blower enabled or disabled. Always revert to testing with the 
indoor blower disabled if cyclic testing with the fan enabled is 
unsuccessful.
    a. For all cyclic tests, the measured capacity must be adjusted for 
the thermal mass stored in devices and connections located between 
measured points. Follow the procedure outlined in section 7.4.3.4.5 of 
ASHRAE 116-2010 (incorporated by reference, see Sec. 430.3) to ensure 
any required measurements are taken.
    b. For units having a single-speed or two-capacity compressor, cycle 
the compressor OFF for 24 minutes and then ON for 6 minutes 
([Delta][tau]cyc,dry = 0.5 hours). For units having a 
variable-speed compressor, cycle the compressor OFF for 48 minutes and 
then ON for 12 minutes ([Delta][tau]cyc,dry = 1.0 hours). 
Repeat the OFF/ON compressor cycling pattern until the test is 
completed. Allow the controls of the unit to regulate cycling of the 
outdoor fan. If an upturned duct is used, measure the dry-bulb 
temperature at the inlet of the device at least once every minute and 
ensure that its test operating tolerance is within 1.0 [deg]F for each 
compressor OFF period.
    c. Sections 3.5.1 and 3.5.2 of this appendix specify airflow 
requirements through the indoor coil of ducted and non-ducted indoor 
units, respectively. In all cases, use the exhaust fan of the airflow 
measuring apparatus (covered under section 2.6 of this appendix) along 
with the indoor blower of the unit, if installed and operating, to 
approximate a step response in the indoor coil airflow. Regulate the 
exhaust fan to quickly obtain and then maintain the flow nozzle static 
pressure difference or velocity pressure at the same value as was 
measured during the steady-state dry coil test. The pressure difference 
or velocity pressure should be within 2 percent of the value from the 
steady-state dry coil test within 15 seconds after airflow initiation. 
For units having a variable-speed indoor blower that ramps when cycling 
on and/or off, use the exhaust fan of the airflow measuring apparatus to 
impose a step response that begins at the initiation of ramp up and ends 
at the termination of ramp down.
    d. For units having a variable-speed indoor blower, conduct the 
cyclic dry coil test using the pull-thru approach described below if any 
of the following occur when testing with the fan operating:
    (1) The test unit automatically cycles off;

[[Page 495]]

    (2) Its blower motor reverses; or
    (3) The unit operates for more than 30 seconds at an external static 
pressure that is 0.1 inches of water or more higher than the value 
measured during the prior steady-state test.
    For the pull-thru approach, disable the indoor blower and use the 
exhaust fan of the airflow measuring apparatus to generate the specified 
flow nozzles static pressure difference or velocity pressure. If the 
exhaust fan cannot deliver the required pressure difference because of 
resistance created by the unpowered indoor blower, temporarily remove 
the indoor blower.
    e. Conduct three complete compressor OFF/ON cycles with the test 
tolerances given in Table 10 satisfied. Calculate the degradation 
coefficient CD for each complete cycle. If all three 
CD values are within 0.02 of the average CD then 
stability has been achieved, and the highest CD value of 
these three shall be used. If stability has not been achieved, conduct 
additional cycles, up to a maximum of eight cycles total, until 
stability has been achieved between three consecutive cycles. Once 
stability has been achieved, use the highest CD value of the 
three consecutive cycles that establish stability. If stability has not 
been achieved after eight cycles, use the highest CD from 
cycle one through cycle eight, or the default CD, whichever 
is lower.
    f. With regard to the Table 10 parameters, continuously record the 
dry-bulb temperature of the air entering the indoor and outdoor coils 
during periods when air flows through the respective coils. Sample the 
water vapor content of the indoor coil inlet air at least every 2 
minutes during periods when air flows through the coil. Record external 
static pressure and the air volume rate indicator (either nozzle 
pressure difference or velocity pressure) at least every minute during 
the interval that air flows through the indoor coil. (These regular 
measurements of the airflow rate indicator are in addition to the 
required measurement at 15 seconds after flow initiation.) Sample the 
electrical voltage at least every 2 minutes beginning 30 seconds after 
compressor start-up. Continue until the compressor, the outdoor fan, and 
the indoor blower (if it is installed and operating) cycle off.
    g. For ducted units, continuously record the dry-bulb temperature of 
the air entering (as noted above) and leaving the indoor coil. Or if 
using a thermopile, continuously record the difference between these two 
temperatures during the interval that air flows through the indoor coil. 
For non-ducted units, make the same dry-bulb temperature measurements 
beginning when the compressor cycles on and ending when indoor coil 
airflow ceases.
    h. Integrate the electrical power over complete cycles of length 
[Delta][tau]cyc,dry. For ducted blower coil systems tested 
with the unit's indoor blower operating for the cycling test, integrate 
electrical power from indoor blower OFF to indoor blower OFF. For all 
other ducted units and for non-ducted units, integrate electrical power 
from compressor OFF to compressor OFF. (Some cyclic tests will use the 
same data collection intervals to determine the electrical energy and 
the total space cooling. For other units, terminate data collection used 
to determine the electrical energy before terminating data collection 
used to determine total space cooling.)

          during the section 3.4 dry coil steady-state test and
Tal([tau]) = dry bulb temperature of the air entering the 
          indoor coil at time [tau], [deg]F.
Ta2([tau]) = dry bulb temperature of the air leaving the 
          indoor coil at time [tau], [deg]F.
[tau]1 = for ducted units, the elapsed time when airflow is 
          initiated through the indoor coil; for non-ducted units, the 
          elapsed time when the compressor is cycled on, hr.
[tau]2 = the elapsed time when indoor coil airflow ceases, 
          hr.

    Adjust the total space cooling delivered, qcyc,dry, 
according to calculation method outlined in section 7.4.3.4.5 of ASHRAE 
116-2010 (incorporated by reference, see Sec. 430.3).

              3.5.1 Procedures When Testing Ducted Systems

    The automatic controls that are installed in the test unit must 
govern the OFF/ON cycling of the air moving equipment on the indoor side 
(exhaust fan of the airflow measuring apparatus and the indoor blower of 
the test unit). For ducted coil-only systems rated based on using a fan 
time-delay relay, control the indoor coil airflow according to the OFF 
delay listed by the manufacturer in the certification report. For ducted 
units having a variable-speed indoor blower that has been disabled (and 
possibly removed), start and stop the indoor airflow at the same 
instances as if the fan were enabled. For all other ducted coil-only 
systems, cycle the indoor coil airflow in unison with the cycling of the 
compressor. If air damper boxes are used, close them on the inlet and 
outlet side during the OFF period. Airflow through the indoor coil 
should stop within 3 seconds after the automatic controls of the test 
unit (act to) de-energize the indoor blower. For ducted coil-only 
systems (excluding the special case where a variable-speed fan is 
temporarily removed), increase ecyc,dry by the quantity,
[GRAPHIC] [TIFF OMITTED] TR05JA17.018

    and decrease qcyc,dry by,
    [GRAPHIC] [TIFF OMITTED] TR05JA17.019
    
where VIs is the average indoor air volume rate from the 
          section 3.4 dry coil steady-state test and is expressed in 
          units of cubic feet per minute of standard air (scfm). For 
          units having a variable-speed indoor blower that is disabled 
          during the cyclic test, increase ecyc,dry and 
          decrease qcyc,dry based on:
a. The product of [[tau]2 - [tau]1] and the indoor 
          blower power measured during or following the dry coil steady-
          state test; or,
b. The following algorithm if the indoor blower ramps its speed when 
          cycling.

    (1) Measure the electrical power consumed by the variable-speed 
indoor blower at a minimum of three operating conditions: At the speed/
air volume rate/external static pressure that was measured during the 
steady-state test, at operating conditions associated with the midpoint 
of the ramp-up interval, and at conditions associated with the midpoint 
of the ramp-down interval. For these measurements, the tolerances on the 
airflow volume or the external static pressure are the same as required 
for the section 3.4 steady-state test.
    (2) For each case, determine the fan power from measurements made 
over a minimum of 5 minutes.
    (3) Approximate the electrical energy consumption of the indoor 
blower if it had operated during the cyclic test using all three power 
measurements. Assume a linear profile during the ramp intervals. The 
manufacturer must provide the durations of the ramp-up and ramp-down 
intervals. If the test setup instructions included with the unit by the 
manufacturer specifies a ramp interval that exceeds 45 seconds, use a 
45-second ramp interval nonetheless when estimating the fan energy.

          3.5.2 Procedures When Testing Non-Ducted Indoor Units

    Do not use airflow prevention devices when conducting cyclic tests 
on non-ducted indoor units. Until the last OFF/ON compressor cycle, 
airflow through the indoor coil must

[[Page 497]]

cycle off and on in unison with the compressor. For the last OFF/ON 
compressor cycle--the one used to determine ecyc,dry and 
qcyc,dry--use the exhaust fan of the airflow measuring 
apparatus and the indoor blower of the test unit to have indoor airflow 
start 3 minutes prior to compressor cut-on and end three minutes after 
compressor cutoff. Subtract the electrical energy used by the indoor 
blower during the 3 minutes prior to compressor cut-on from the 
integrated electrical energy, ecyc,dry. Add the electrical 
energy used by the indoor blower during the 3 minutes after compressor 
cutoff to the integrated cooling capacity, qcyc,dry. For the 
case where the non-ducted indoor unit uses a variable-speed indoor 
blower which is disabled during the cyclic test, correct 
ecyc,dry and qcyc,dry using the same approach as 
prescribed in section 3.5.1 of this appendix for ducted units having a 
disabled variable-speed indoor blower.

      3.5.3 Cooling-Mode Cyclic-Degradation Coefficient Calculation

    Use the two dry-coil tests to determine the cooling-mode cyclic-
degradation coefficient, CD\c\. Append ``(k=2)'' to the 
coefficient if it corresponds to a two-capacity unit cycling at high 
capacity. If the two optional tests are conducted but yield a tested 
CD\c\ that exceeds the default CD\c\ or if the two optional tests are 
not conducted, assign CD\c\ the default value of 0.25 for variable-speed 
compressor systems and outdoor units with no match, and 0.20 for all 
other systems. The default value for two-capacity units cycling at high 
capacity, however, is the low-capacity coefficient, i.e., 
CD\c\(k=2) = CD\c\. Evaluate CD\c\ 
using the above results and those from the section 3.4 dry-coil steady-
state test.

  3.6 Heating Mode Tests for Different Types of Heat Pumps, Including 
                         Heating-Only Heat Pumps

 3.6.1 Tests for a Heat Pump Having a Single-Speed Compressor and Fixed 
                         Heating Air Volume Rate

    This set of tests is for single-speed-compressor heat pumps that do 
not have a heating minimum air volume rate or a heating intermediate air 
volume rate that is different than the heating full load air volume 
rate. Conduct the optional high temperature cyclic (H1C) test to 
determine the heating mode cyclic-degradation coefficient, 
CD\h\. If this optional test is conducted but yields a tested 
CD\h\ that exceeds the default CD\h\ or if the 
optional test is not conducted, assign CD\h\ the default 
value of 0.25. Test conditions for the four tests are specified in Table 
10.

    Conduct five tests: Two high temperature tests (H12 and 
H11), one frost accumulation test (H22), and two 
low temperature tests (H32 and H31). Conducting an 
additional frost accumulation test (H21) is optional. Conduct 
the optional high temperature cyclic (H1C1) test to determine 
the heating mode cyclic-degradation coefficient, CD\h\. If 
this optional test is conducted but yields a tested CD\h\ 
that exceeds the default CD\h\ or if the optional test is not 
conducted, assign CD\h\ the default value of 0.25. Test 
conditions for the seven tests are specified in Table 12. If the 
optional H21 test is not performed, use the following 
equations to approximate the capacity and electrical power of the heat 
pump at the H21 test conditions:

   3.6.3 Tests for a Heat Pump Having a Two-Capacity Compressor (see 
  section 1.2 of this appendix, Definitions), Including Two-Capacity, 
   Northern Heat Pumps (see section 1.2 of this appendix, Definitions)

    a. Conduct one maximum temperature test (H01), two high 
temperature tests (H12and H11), one frost 
accumulation test (H22), and one low temperature test 
(H32). Conduct an additional frost accumulation test 
(H21) and low temperature test (H31) if both of 
the following conditions exist:
    (1) Knowledge of the heat pump's capacity and electrical power at 
low compressor capacity for outdoor temperatures of 37 [deg]F and less 
is needed to complete the section 4.2.3 of this appendix seasonal 
performance calculations; and
    (2) The heat pump's controls allow low-capacity operation at outdoor 
temperatures of 37 [deg]F and less.
    If the above two conditions are met, an alternative to conducting 
the H21 frost accumulation is to use the following equations 
to approximate the capacity and electrical power:

    Determine the quantities Qh\k=1\ (47) and Eh\k=1\ (47) from the

appendix. Determine the quantities Qh\k=1\ (17) and Eh\k=1\ (17) from 
the H31 test and evaluate them according to section 3.10 of 
this appendix.
    b. Conduct the optional high temperature cyclic test 
(H1C1) to determine the heating mode cyclic-degradation 
coefficient, CD\h\. If this optional test is conducted but 
yields a tested CD\h\ that exceeds the default 
CD\h\ or if the optional test is not conducted, assign 
CD\h\ the default value of 0.25. If a two-capacity heat pump 
locks out low capacity operation at lower outdoor temperatures, conduct 
the high temperature cyclic test (H1C 2) to determine the 
high-capacity heating mode cyclic-degradation coefficient, 
CD\h\ (k=2). If this optional test at high capacity is 
conducted but yields a tested CD\h\ (k = 2) that exceeds the 
default CD\h\ (k = 2) or if the optional test is not 
conducted, assign CD\h\ the default value. The default 
CD\h\ (k=2) is the same value as determined or assigned for 
the low-capacity cyclic-degradation coefficient, CD\h\ [or 
equivalently, CD\h\ (k=1)]. Table 13 specifies test 
conditions for these nine tests.

     3.6.4 Tests for a Heat Pump Having a Variable-Speed Compressor

    a. Conduct one maximum temperature test (H01), two high 
temperature tests (H1N and H11), one frost 
accumulation test (H2V), and one low temperature test 
(H32). Conducting one or both of the following tests is 
optional: An additional high temperature test (H12) and an 
additional frost accumulation test (H22). If desired, conduct 
the optional maximum temperature cyclic (H0C1) test to 
determine the heating mode cyclic-degradation coefficient, 
CD\h\. If this optional test is conducted but yields a tested 
CD\h\ that exceeds the default CD\h\ or if the 
optional test is not conducted, assign CD\h\ the default 
value of 0.25. Test conditions for the eight tests are specified in 
Table 14. The compressor shall operate at the same heating full speed, 
measured by RPM or power input frequency (Hz), for the H12, 
H22 and H32 tests. For a cooling/heating heat 
pump, the compressor shall operate for the H1N test at a 
speed, measured by RPM or power input frequency (Hz), no lower than the

heating capacity is less than the tested cooling capacity in 
A2 test. The compressor shall operate at the same heating 
minimum speed, measured by RPM or power input frequency (Hz), for the 
H01, H1C1, and H11 tests. Determine the 
heating intermediate compressor speed cited in Table 14 using the

frequency step from the calculated value is allowed.

    Otherwise, if the H1N test is conducted using the same 
compressor speed (RPM or power input frequency) as the H32 
test, set the 47 [deg]F capacity and power input values used for 
calculation of HSPF equal to the measured values for that test:

Ehk=N(47) is the power input measured in the H1N test.

    Evaluate the quantities Qhk=N(47) and from Ehk=N(47) according to 
section 3.7.
    Otherwise (if no high temperature test is conducted using the same 
speed (RPM or power input frequency) as the H32 test), 
calculate the 47 [deg]F capacity and power input values used for 
calculation of HSPF as follows:

 3.6.5 Additional Test for a Heat Pump Having a Heat Comfort Controller

    Test any heat pump that has a heat comfort controller (see section 
1.2 of this appendix, Definitions) according to section 3.6.1, 3.6.2, or 
3.6.3, whichever applies, with the heat comfort controller disabled. 
Additionally, conduct the abbreviated test described in section 3.1.10 
of this appendix with the heat comfort controller active to determine 
the system's maximum supply air temperature. (Note: Heat pumps having a 
variable speed compressor and a heat comfort controller are not covered 
in the test procedure at this time.)

 3.6.6 Heating Mode Tests for Northern Heat Pumps With Triple-Capacity 
                              Compressors.

    Test triple-capacity, northern heat pumps for the heating mode as 
follows:
    a. Conduct one maximum-temperature test (H01), two high-
temperature tests (H12 and H11), one frost 
accumulation test (H22), two low-temperature tests 
(H32, H33), and one minimum-temperature test 
(H43). Conduct an additional frost accumulation test 
(H21) and low-temperature test (H31) if both of 
the following conditions exist: (1) Knowledge of the heat pump's 
capacity and electrical power at low compressor capacity for outdoor 
temperatures of 37 [deg]F and less is needed to complete the section 
4.2.6 seasonal performance calculations; and (2) the heat pump's 
controls allow low-capacity operation at outdoor temperatures of 37 
[deg]F and less. If the above two conditions are met, an alternative to 
conducting the H21 frost accumulation test to determine 
Qh\k=1\(35) and Ehk=1(35) is to use the following equations to 
approximate this capacity and electrical power:

[[Page 503]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.310

    In evaluating the above equations, determine the quantities 
Qhk=1(47) from the H11 test and evaluate them according to 
section 3.7 of this appendix. Determine the quantities Qhk=1(17) and 
Eh\k=1\(17) from the H31 test and evaluate them according to 
section 3.10 of this appendix. Use the paired values of Qh\k=1\(35) and 
Eh\k=1\(35) derived from conducting the H21 frost 
accumulation test and evaluated as specified in section 3.9.1 of this 
appendix or use the paired values calculated using the above default 
equations, whichever contribute to a higher Region IV HSPF based on the 
DHRmin.
    b. Conducting a frost accumulation test (H23) with the 
heat pump operating at its booster capacity is optional. If this 
optional test is not conducted, determine Qh\k=3\(35) and Ehk=3(35) 
using the following equations to approximate this capacity and 
electrical power:
[GRAPHIC] [TIFF OMITTED] TR05JA17.311

Where:
[GRAPHIC] [TIFF OMITTED] TR05JA17.026

    Determine the quantities Qhk=2(47) and Ehk=2(47) from the 
H12 test and evaluate them according to section 3.7 of this 
appendix. Determine the quantities Qhk=2(35) and Ehk=2(35) from the 
H22 test and evaluate them according to section 3.9.1 of this 
appendix. Determine the quantities Qhk=2(17) and Ehk=2(17) from the 
H32 test, determine the quantities Qh\k=3\(17) and Ehk=3(17) 
from the H33 test, and determine the quantities Qhk=3(5) and 
Ehk=3(5) from the H43 test. Evaluate all six quantities 
according to section 3.10 of this appendix. Use the paired values of 
Qhk=3(35) and Ehk=3(35) derived from conducting the H23 frost 
accumulation test and calculated as specified in section 3.9.1 of this 
appendix or use the paired values calculated using the above default 
equations, whichever contribute to a higher Region IV HSPF2 based on the 
DHRmin.
    c. Conduct the optional high-temperature cyclic test 
(H1C1) to determine the heating mode cyclic-degradation 
coefficient, CD\h\. A default value for CD\h\ may 
be used in lieu of conducting the cyclic. The default value of 
CD\h\ is 0.25. If a triple-capacity heat pump locks out low 
capacity operation at lower outdoor temperatures, conduct the high-
temperature cyclic test (H1C2) to determine the high-capacity 
heating mode cyclic-degradation coefficient, CD\h\ (k=2). The 
default CD\h\ (k=2) is the same value as determined or 
assigned for the low-capacity cyclic-degradation coefficient, 
CD\h\ [or equivalently, CD\h\ (k=1)]. Finally, if 
a triple-capacity heat pump locks out both low and high capacity 
operation at the lowest outdoor temperatures, conduct the low-
temperature cyclic test (H3C3) to determine the booster-
capacity heating mode cyclic-degradation coefficient,

[[Page 504]]

CD\h\ (k=3). The default CD\h\ (k=3) is the same 
value as determined or assigned for the high-capacity cyclic-degradation 
coefficient, CD\h\ [or equivalently, CD\h\ (k=2)]. 
Table 15 specifies test conditions for all 13 tests.

3.6.7 Tests for a Heat Pump Having a Single Indoor Unit Having Multiple 
     Indoor Blowers and Offering Two Stages of Compressor Modulation

    Conduct the heating mode tests specified in section 3.6.3 of this 
appendix.

   3.7 Test Procedures for Steady-State Maximum Temperature and High 
  Temperature Heating Mode Tests (the H01, H1, H12, H11, and H1N Tests)

    a. For the pretest interval, operate the test room reconditioning 
apparatus and the heat pump until equilibrium conditions are maintained 
for at least 30 minutes at the specified section 3.6 test conditions. 
Use the exhaust fan of the airflow measuring apparatus and, if 
installed, the indoor blower of the heat pump to obtain and then 
maintain the indoor air volume rate and/or the external static pressure 
specified for the particular test. Continuously record the dry-bulb 
temperature of the air entering the indoor coil, and the dry-bulb 
temperature and water vapor content of the air entering the outdoor 
coil. Refer to section 3.11 of this appendix for additional requirements 
that depend on the selected secondary test method. After satisfying the 
pretest equilibrium requirements, make the measurements specified in 
Table 3 of ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 
430.3) for the indoor air enthalpy method and the user-selected 
secondary method. Make said Table 3 measurements at equal intervals that 
span 5 minutes or less. Continue data sampling until a 30-minute period 
(e.g., seven consecutive 5-minute samples) is reached where the test 
tolerances specified in Table 16 are satisfied. For those continuously 
recorded parameters, use the entire data set for the 30-minute interval 
when evaluating Table 16 compliance. Determine the average electrical 
power consumption of the heat pump over the same 30-minute interval.

    b. Calculate indoor-side total heating capacity as specified in 
sections 7.3.4.1 and 7.3.4.3 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3). To calculate capacity, use the averages of 
the measurements (e.g. inlet and outlet dry bulb temperatures measured 
at the psychrometers) that are continuously recorded for the same 30-
minute interval used as described above to evaluate compliance with test 
tolerances. Do not adjust the parameters used in calculating capacity 
for the permitted variations in test conditions. Assign the average 
space heating capacity and electrical power over the 30-minute data 
collection interval to the variables Qh\k\ and Eh\k\(T) respectively. 
The ``T'' and superscripted ``k'' are the same as described in section 
3.3 of this appendix. Additionally, for the heating mode, use the 
superscript to denote results from the optional H1N test, if 
conducted.
    c. For coil-only system heat pumps, increase Qh\k\(T) by
    [GRAPHIC] [TIFF OMITTED] TR05JA17.028
    
where Vis is the average measured indoor air volume rate 
expressed in units of cubic feet per minute of standard air (scfm). 
During the 30-minute data collection interval of a high temperature 
test, pay attention to preventing a defrost cycle. Prior to this time, 
allow the heat pump to perform a defrost cycle if automatically 
initiated by its own controls. As in all cases, wait for the heat pump's 
defrost controls to automatically terminate the defrost cycle. Heat 
pumps that undergo a defrost should operate in the heating mode for at 
least 10 minutes after defrost termination prior to beginning the 30-
minute data collection interval. For some heat pumps, frost may 
accumulate on the outdoor coil during a high temperature test. If the 
indoor coil leaving air temperature or the difference between the 
leaving and entering air temperatures decreases by more than 1.5 [deg]F 
over the 30-minute data collection interval, then do not use the 
collected data to determine capacity. Instead, initiate a defrost cycle. 
Begin collecting data no sooner than 10 minutes after defrost 
termination. Collect 30 minutes of new data during which the Table 16 
test tolerances are satisfied. In this case, use only the results from 
the second 30-minute data collection interval to evaluate Qh\k\(47) and 
Eh\k\(47).
    d. If conducting the cyclic heating mode test, which is described in 
section 3.8 of this appendix, record the average indoor-side air volume 
rate, Vi, specific heat of the air, Cp,a (expressed on dry 
air basis), specific volume of the air at the nozzles, 
vn[min] (or vn), humidity ratio at the nozzles, 
Wn, and either pressure difference or velocity pressure for 
the flow nozzles. If either or both of the below criteria apply, 
determine the average, steady-state, electrical power consumption of the 
indoor blower motor (Efan,1):
    (1) The section 3.8 cyclic test will be conducted and the heat pump 
has a variable-speed indoor blower that is expected to be disabled 
during the cyclic test; or
    (2) The heat pump has a (variable-speed) constant-air volume-rate 
indoor blower and during the steady-state test the average external 
static pressure ([Delta]P1) exceeds the applicable section 
3.1.4.4 minimum (or targeted) external static pressure 
([Delta]Pmin) by 0.03 inches of water or more.
    Determine Efan,1 by making measurements during the 30-
minute data collection interval, or immediately following the test and 
prior to changing the test conditions. When the above ``2'' criteria 
applies, conduct the following four steps after determining 
Efan,1 (which corresponds to [Delta]P1):
    (i) While maintaining the same test conditions, adjust the exhaust 
fan of the airflow measuring apparatus until the external static 
pressure increases to approximately [Delta]P1 + 
([Delta]P1 - [Delta]Pmin).
    (ii) After re-establishing steady readings for fan motor power and 
external static pressure, determine average values for the indoor blower 
power (Efan,2) and the external static pressure 
([Delta]P2) by making measurements over a 5-minute interval.
    (iii) Approximate the average power consumption of the indoor blower 
motor if the 30-minute test had been conducted at [Delta]Pmin 
using linear extrapolation:

[[Page 506]]

    (iv) Decrease the total space heating capacity, Qhk(T), by the 
quantity (Efan,1 - Efan,min), when expressed on a 
Btu/h basis. Decrease the total electrical power, Ehk(T) by the same fan 
power difference, now expressed in watts.
    e. If the temperature sensors used to provide the primary 
measurement of the indoor-side dry bulb temperature difference during 
the steady-state dry-coil test and the subsequent cyclic dry-coil test 
are different, include measurements of the latter sensors among the 
regularly sampled data. Beginning at the start of the 30-minute data 
collection period, measure and compute the indoor-side air dry-bulb 
temperature difference using both sets of instrumentation, [Delta]T (Set 
SS) and [Delta]T (Set CYC), for each equally spaced data sample. If 
using a consistent data sampling rate that is less than 1 minute, 
calculate and record minutely averages for the two temperature 
differences. If using a consistent sampling rate of one minute or more, 
calculate and record the two temperature differences from each data 
sample. After having recorded the seventh (i=7) set of temperature 
differences, calculate the following ratio using the first seven sets of 
values:
[GRAPHIC] [TIFF OMITTED] TR05JA17.030

Each time a subsequent set of temperature differences is recorded (if 
sampling more frequently than every 5 minutes), calculate FCD using the 
most recent seven sets of values. Continue these calculations until the 
30-minute period is completed or until a value for FCD is calculated 
that falls outside the allowable range of 0.94-1.06. If the latter 
occurs, immediately suspend the test and identify the cause for the 
disparity in the two temperature difference measurements. Recalibration 
of one or both sets of instrumentation may be required. If all the 
values for FCD are within the allowable range, save the final value of 
the ratio from the 30-minute test as FCD*. If the temperature sensors 
used to provide the primary measurement of the indoor-side dry bulb 
temperature difference during the steady-state dry-coil test and the 
subsequent cyclic dry-coil test are the same, set FCD*= 1.

 3.8 Test Procedures for the Cyclic Heating Mode Tests (the H0C1, H1C, 
                          H1C1 and H1C2 Tests)

    a. Except as noted below, conduct the cyclic heating mode test as 
specified in section 3.5 of this appendix. As adapted to the heating 
mode, replace section 3.5 references to ``the steady-state dry coil 
test'' with ``the heating mode steady-state test conducted at the same 
test conditions as the cyclic heating mode test.'' Use the test 
tolerances in Table 17 rather than Table 10. Record the outdoor coil 
entering wet-bulb temperature according to the requirements given in 
section 3.5 of this appendix for the outdoor coil entering dry-bulb 
temperature. Drop the subscript ``dry'' used in variables cited in 
section 3.5 of this appendix when referring to quantities from the 
cyclic heating mode test. Determine the total space heating delivered 
during the cyclic heating test, qcyc, as specified in section 
3.5 of this appendix except for making the following changes:
    (1) When evaluating Equation 3.5-1, use the values of Vi, 
Cp,a,vn[min], (or vn), and 
Wn that were recorded during the section 3.7 steady-state 
test conducted at the same test conditions.
    (2) Calculate [Gamma] using
    [GRAPHIC] [TIFF OMITTED] TR05JA17.031
    

[[Page 507]]


where FCD* is the value recorded during the section 3.7 steady-state 
test conducted at the same test condition.
    b. For ducted coil-only system heat pumps (excluding the special 
case where a variable-speed fan is temporarily removed), increase 
qcyc by the amount calculated using Equation 3.5-3. 
Additionally, increase ecyc by the amount calculated using 
Equation 3.5-2. In making these calculations, use the average indoor air 
volume rate (Vis) determined from the section 3.7 steady-
state heating mode test conducted at the same test conditions.
    c. For non-ducted heat pumps, subtract the electrical energy used by 
the indoor blower during the 3 minutes after compressor cutoff from the 
non-ducted heat pump's integrated heating capacity, qcyc.
    d. If a heat pump defrost cycle is manually or automatically 
initiated immediately prior to or during the OFF/ON cycling, operate the 
heat pump continuously until 10 minutes after defrost termination. After 
that, begin cycling the heat pump immediately or delay until the 
specified test conditions have been re-established. Pay attention to 
preventing defrosts after beginning the cycling process. For heat pumps 
that cycle off the indoor blower during a defrost cycle, make no effort 
here to restrict the air movement through the indoor coil while the fan 
is off. Resume the OFF/ON cycling while conducting a minimum of two 
complete compressor OFF/ON cycles before determining qcyc and 
ecyc.

      3.8.1 Heating Mode Cyclic-Degradation Coefficient Calculation

    Use the results from the required cyclic test and the required 
steady-state test that were conducted at the same test conditions to 
determine the heating mode cyclic-degradation coefficient 
CD\h\. Add ``(k=2)'' to the coefficient if it corresponds to 
a two-capacity unit cycling at high capacity. For the below calculation 
of the heating mode cyclic degradation coefficient, do not include the 
duct loss correction from section 7.3.3.3 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3) in determining 
Qh\k\(Tcyc) (or qcyc). If the optional cyclic test 
is conducted but yields a tested CD\h\ that exceeds the 
default CD\h\ or if the optional test is not conducted, 
assign CD\h\ the default value of 0.25. The default value for 
two-capacity units cycling at high capacity, however, is the low-
capacity coefficient, i.e., CD\h\ (k=2) = CD\h\. 
The tested CD\h\ is calculated as follows:

          heating mode test, dimensionless.

Tcyc = the nominal outdoor temperature at which the cyclic 
          heating mode test is conducted, 62 or 47 [deg]F.

          hours when testing a heat pump having a single-speed or two-
          capacity compressor and 1.0 hour when testing a heat pump 
          having a variable-speed compressor.

    Round the calculated value for CD\h\ to the nearest 0.01. 
If CD\h\ is negative, then set it equal to zero.

 3.9 Test Procedures for Frost Accumulation Heating Mode Tests (the H2, 
                        H22, H2V, and H21 tests)

    a. Confirm that the defrost controls of the heat pump are set as 
specified in section 2.2.1 of this appendix. Operate the test room 
reconditioning apparatus and the heat pump for at least 30 minutes at 
the specified section 3.6 test conditions before starting the 
``preliminary'' test period. The preliminary test period must 
immediately precede the ``official'' test period, which is the heating 
and defrost interval over which data are collected for evaluating 
average space heating capacity and average electrical power consumption.
    b. For heat pumps containing defrost controls which are likely to 
cause defrosts at intervals less than one hour, the preliminary test 
period starts at the termination of an automatic defrost cycle and ends 
at the termination of the next occurring automatic defrost cycle. For 
heat pumps containing defrost controls which are likely to cause 
defrosts at intervals exceeding one hour, the preliminary test period 
must consist of a heating interval lasting at least one hour followed by 
a defrost cycle that is either manually or automatically initiated. In 
all cases, the heat pump's own controls must govern when a defrost cycle 
terminates.
    c. The official test period begins when the preliminary test period 
ends, at defrost termination. The official test period ends at the 
termination of the next occurring automatic defrost cycle. When testing 
a heat pump that uses a time-adaptive defrost control system (see 
section 1.2 of this appendix, Definitions), however, manually initiate 
the defrost cycle that ends the official test period at the instant 
indicated by instructions provided by the manufacturer. If the heat pump 
has not undergone a defrost after 6 hours, immediately conclude the test 
and use the results from the full 6-hour period to calculate the average 
space heating capacity and average electrical power consumption.
    For heat pumps that turn the indoor blower off during the defrost 
cycle, take steps to cease forced airflow through the indoor coil and 
block the outlet duct whenever the heat pump's controls cycle off the 
indoor blower. If it is installed, use the outlet damper box described 
in section 2.5.4.1 of this appendix to affect the blocked outlet duct.
    d. Defrost termination occurs when the controls of the heat pump 
actuate the first change in converting from defrost operation to normal 
heating operation. Defrost initiation occurs when the controls of the 
heat pump first alter its normal heating operation in order to eliminate 
possible accumulations of frost on the outdoor coil.

[[Page 509]]

    e. To constitute a valid frost accumulation test, satisfy the test 
tolerances specified in Table 18 during both the preliminary and 
official test periods. As noted in Table 18, test operating tolerances 
are specified for two sub-intervals:
    (1) When heating, except for the first 10 minutes after the 
termination of a defrost cycle (sub-interval H, as described in Table 
18) and
    (2) When defrosting, plus these same first 10 minutes after defrost 
termination (sub-interval D, as described in Table 18). Evaluate 
compliance with Table 18 test condition tolerances and the majority of 
the test operating tolerances using the averages from measurements 
recorded only during sub-interval H. Continuously record the dry bulb 
temperature of the air entering the indoor coil, and the dry bulb 
temperature and water vapor content of the air entering the outdoor 
coil. Sample the remaining parameters listed in Table 18 at equal 
intervals that span 5 minutes or less.
    f. For the official test period, collect and use the following data 
to calculate average space heating capacity and electrical power. During 
heating and defrosting intervals when the controls of the heat pump have 
the indoor blower on, continuously record the dry-bulb temperature of 
the air entering (as noted above) and leaving the indoor coil. If using 
a thermopile, continuously record the difference between the leaving and 
entering dry-bulb temperatures during the interval(s) that air flows 
through the indoor coil. For coil-only system heat pumps, determine the 
corresponding cumulative time (in hours) of indoor coil airflow, 
[Delta][tau]a. Sample measurements used in calculating the 
air volume rate (refer to sections 7.7.2.1 and 7.7.2.2 of ANSI/ASHRAE 
37-2009) at equal intervals that span 10 minutes or less. (Note: In the 
first printing of ANSI/ASHRAE 37-2009, the second IP equation for 
Qmi should read:) Record the electrical energy consumed, 
expressed in watt-hours, from defrost termination to defrost 
termination, eDEF\k\(35), as well as the corresponding 
elapsed time in hours, [Delta][tau]FR.

 3.9.1 Average Space Heating Capacity and Electrical Power Calculations

    a. Evaluate average space heating capacity, Qh\k\(35), when 
expressed in units of Btu per hour, using:
[GRAPHIC] [TIFF OMITTED] TR05JA17.036

Where,

Vi = the average indoor air volume rate measured during sub-interval H, 
          cfm.
Cp,a = 0.24 + 0.444 [middot] Wn, the constant 
          pressure specific heat of the air-water vapor mixture that 
          flows through the indoor coil and is expressed on a dry air 
          basis, Btu/lbmda [middot] [deg]F.

[[Page 510]]

vn[min] = specific volume of the air-water vapor mixture at 
          the nozzle, ft\3\/lbmmx.
Wn = humidity ratio of the air-water vapor mixture at the 
          nozzle, lbm of water vapor per lbm of dry air.
[Delta][tau]FR = [tau]2 - [tau]1, the 
          elapsed time from defrost termination to defrost termination, 
          hr.
          [GRAPHIC] [TIFF OMITTED] TR05JA17.312
          
Tal([tau]) = dry bulb temperature of the air entering the 
          indoor coil at elapsed time [tau], [deg]F; only recorded when 
          indoor coil airflow occurs; assigned the value of zero during 
          periods (if any) where the indoor blower cycles off.
Ta2([tau]) = dry bulb temperature of the air leaving the 
          indoor coil at elapsed time [tau], [deg]F; only recorded when 
          indoor coil airflow occurs; assigned the value of zero during 
          periods (if any) where the indoor blower cycles off.
[tau]1 = the elapsed time when the defrost termination occurs 
          that begins the official test period, hr.
[tau]2 = the elapsed time when the next automatically 
          occurring defrost termination occurs, thus ending the official 
          test period, hr.
vn = specific volume of the dry air portion of the mixture 
          evaluated at the dry-bulb temperature, vapor content, and 
          barometric pressure existing at the nozzle, ft\3\ per lbm of 
          dry air.

    To account for the effect of duct losses between the outlet of the 
indoor unit and the section 2.5.4 dry-bulb temperature grid, adjust 
Qh\k\(35) in accordance with section 7.3.4.3 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3).
    b. Evaluate average electrical power, Eh\k\(35), when expressed in 
units of watts, using:
[GRAPHIC] [TIFF OMITTED] TR05JA17.037

    For coil-only system heat pumps, increase Qh\k\(35) by,
    [GRAPHIC] [TIFF OMITTED] TR05JA17.038
    
and increase Eh\k\(35) by,
[GRAPHIC] [TIFF OMITTED] TR05JA17.039

where Vis is the average indoor air volume rate measured 
during the frost accumulation heating mode test and is expressed in 
units of cubic feet per minute of standard air (scfm).
    c. For heat pumps having a constant-air-volume-rate indoor blower, 
the five additional steps listed below are required if the average of 
the external static pressures measured during sub-interval H exceeds the 
applicable section 3.1.4.4, 3.1.4.5, or 3.1.4.6 minimum (or targeted) 
external static pressure ([Delta]Pmin) by 0.03 inches of 
water or more:
    (1) Measure the average power consumption of the indoor blower motor 
(Efan,1) and record the corresponding external static 
pressure ([Delta]P1) during or immediately following the 
frost accumulation heating mode test. Make the measurement at a time 
when the heat pump is heating, except for the first 10 minutes after the 
termination of a defrost cycle.
    (2) After the frost accumulation heating mode test is completed and 
while maintaining the same test conditions, adjust the exhaust fan of 
the airflow measuring apparatus until the external static pressure 
increases to approximately [Delta]P1 + ([Delta]P1 
- [Delta]Pmin).
    (3) After re-establishing steady readings for the fan motor power 
and external static pressure, determine average values for the indoor 
blower power (Efan,2) and the external static pressure 
([Delta]P2) by making measurements over a 5-minute interval.
    (4) Approximate the average power consumption of the indoor blower 
motor had the frost accumulation heating mode test been conducted at 
[Delta]Pmin using linear extrapolation:
[GRAPHIC] [TIFF OMITTED] TR05JA17.040


[[Page 511]]


    (5) Decrease the total heating capacity, Qh\k\(35), by the quantity 
[(Efan,1-Efan,min) [middot] ([Delta][tau] 
a/[Delta][tau] FR], when expressed on a Btu/h 
basis. Decrease the total electrical power, Eh\k\(35), by the same 
quantity, now expressed in watts.

                       3.9.2 Demand Defrost Credit

    a. Assign the demand defrost credit, Fdef, that is used 
in section 4.2 of this appendix to the value of 1 in all cases except 
for heat pumps having a demand-defrost control system (see section 1.2 
of this appendix, Definitions). For such qualifying heat pumps, evaluate 
Fdef using,
[GRAPHIC] [TIFF OMITTED] TR05JA17.041

where:
[Delta][tau]def = the time between defrost terminations (in 
          hours) or 1.5, whichever is greater. A value of 6 must be 
          assigned to [Delta][tau]def if this limit is 
          reached during a frost accumulation test and the heat pump has 
          not completed a defrost cycle.
[Delta][tau]max = maximum time between defrosts as allowed by 
          the controls (in hours) or 12, whichever is less, as provided 
          in the certification report.

    b. For two-capacity heat pumps and for section 3.6.2 units, evaluate 
the above equation using the [Delta][tau]def that applies 
based on the frost accumulation test conducted at high capacity and/or 
at the heating full-load air volume rate. For variable-speed heat pumps, 
evaluate [Delta][tau]def based on the required frost 
accumulation test conducted at the intermediate compressor speed.

3.10 Test Procedures for Steady-State Low Temperature Heating Mode Tests 
                      (the H3, H32, and H31 Tests)

    Except for the modifications noted in this section, conduct the low 
temperature heating mode test using the same approach as specified in 
section 3.7 of this appendix for the maximum and high temperature tests. 
After satisfying the section 3.7 requirements for the pretest interval 
but before beginning to collect data to determine Qh\k\(17) and 
Eh\k\(17), conduct a defrost cycle. This defrost cycle may be manually 
or automatically initiated. The defrost sequence must be terminated by 
the action of the heat pump's defrost controls. Begin the 30-minute data 
collection interval described in section 3.7 of this appendix, from 
which Qh\k\(17) and Eh\k\(17) are determined, no sooner than 10 minutes 
after defrost termination. Defrosts should be prevented over the 30-
minute data collection interval.

      3.11 Additional Requirements for the Secondary Test Methodst

 3.11.1 If Using the Outdoor Air Enthalpy Method as the Secondary Test 
                                 Method

    a. For all cooling mode and heating mode tests, first conduct a test 
without the outdoor air-side test apparatus described in section 2.10.1 
of this appendix connected to the outdoor unit (``free outdoor air'' 
test).
    b. For the first section 3.2 steady-state cooling mode test and the 
first section 3.6 steady-state heating mode test, conduct a second test 
in which the outdoor-side apparatus is connected (``ducted outdoor air'' 
test). No other cooling mode or heating mode tests require the ducted 
outdoor air test so long as the unit operates the outdoor fan during all 
cooling mode steady-state tests at the same speed and all heating mode 
steady-state tests at the same speed. If using more than one outdoor fan 
speed for the cooling mode steady-state tests, however, conduct the 
ducted outdoor air test for each cooling mode test where a different fan 
speed is first used. This same requirement applies for the heating mode 
tests.

                     3.11.1.1 Free Outdoor Air Test

    a. For the free outdoor air test, connect the indoor air-side test 
apparatus to the indoor coil; do not connect the outdoor air-side test 
apparatus. Allow the test room reconditioning apparatus and the unit 
being tested to operate for at least one hour. After attaining 
equilibrium conditions, measure the following quantities at equal 
intervals that span 5 minutes or less:
    (1) The section 2.10.1 evaporator and condenser temperatures or 
pressures;
    (2) Parameters required according to the indoor air enthalpy method.
    Continue these measurements until a 30-minute period (e.g., seven 
consecutive 5-minute samples) is obtained where the Table 9 or Table 16, 
whichever applies, test tolerances are satisfied.
    b. For cases where a ducted outdoor air test is not required per 
section 3.11.1.b of this

[[Page 512]]

appendix, the free outdoor air test constitutes the ``official'' test 
for which validity is not based on comparison with a secondary test.
    c. For cases where a ducted outdoor air test is required per section 
3.11.1.b of this appendix, the following conditions must be met for the 
free outdoor air test to constitute a valid ``official'' test:
    (1) Achieve the energy balance specified in section 3.1.1 of this 
appendix for the ducted outdoor air test (i.e., compare the capacities 
determined using the indoor air enthalpy method and the outdoor air 
enthalpy method).
    (2) The capacities determined using the indoor air enthalpy method 
from the ducted outdoor air and free outdoor tests must agree within 2

                    3.11.1.2 Ducted Outdoor Air Test

    a. The test conditions and tolerances for the ducted outdoor air 
test are the same as specified for the free outdoor air test described 
in Section 3.11.1.1 of this appendix.
    b. After collecting 30 minutes of steady-state data during the free 
outdoor air test, connect the outdoor air-side test apparatus to the 
unit for the ducted outdoor air test. Adjust the exhaust fan of the 
outdoor airflow measuring apparatus until averages for the evaporator 
and condenser temperatures, or the saturated temperatures corresponding 
to the measured pressures, agree within 0.5 [deg]F 
of the averages achieved during the free outdoor air test. Collect 30 
minutes of steady-state data after re-establishing equilibrium 
conditions.
    c. During the ducted outdoor air test, at intervals of 5 minutes or 
less, measure the parameters required according to the indoor air 
enthalpy method and the outdoor air enthalpy method for the prescribed 
30 minutes.
    d. For cooling mode ducted outdoor air tests, calculate capacity 
based on outdoor air-enthalpy measurements as specified in sections 
7.3.3.2 and 7.3.3.3 of ANSI/ASHRAE 37-2009 (incorporated by reference, 
see Sec. 430.3). For heating mode ducted tests, calculate heating 
capacity based on outdoor air-enthalpy measurements as specified in 
sections 7.3.4.2 and 7.3.3.4.3 of the same ANSI/ASHRAE Standard. Adjust 
the outdoor-side capacity according to section 7.3.3.4 of ANSI/ASHRAE 
37-2009 to account for line losses when testing split systems. As 
described in section 8.6.2 of ANSI/ASHRAE 37-2009, use the outdoor air 
volume rate as measured during the ducted outdoor air tests to calculate 
capacity for checking the agreement with the capacity calculated using 
the indoor air enthalpy method.

3.11.2 If Using the Compressor Calibration Method as the Secondary Test 
                                 Method

    a. Conduct separate calibration tests using a calorimeter to 
determine the refrigerant flow rate. Or for cases where the superheat of 
the refrigerant leaving the evaporator is less than 5 [deg]F, use the 
calorimeter to measure total capacity rather than refrigerant flow rate. 
Conduct these calibration tests at the same test conditions as specified 
for the tests in this appendix. Operate the unit for at least one hour 
or until obtaining equilibrium conditions before collecting data that 
will be used in determining the average refrigerant flow rate or total 
capacity. Sample the data at equal intervals that span 5 minutes or 
less. Determine average flow rate or average capacity from data sampled 
over a 30-minute period where the Table 9 (cooling) or the Table 16 
(heating) tolerances are satisfied. Otherwise, conduct the calibration 
tests according to sections 5, 6, 7, and 8 of ASHRAE 23.1-2010 
(incorporated by reference, see Sec. 430.3); sections 5, 6, 7, 8, 9, 
and 11 of ASHRAE 41.9-2011 (incorporated by reference, see Sec. 430.3); 
and section 7.4 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3).
    b. Calculate space cooling and space heating capacities using the 
compressor calibration method measurements as specified in section 7.4.5 
and 7.4.6 respectively, of ANSI/ASHRAE 37-2009.

 3.11.3 If Using the Refrigerant-Enthalpy Method as the Secondary Test 
                                 Method

    Conduct this secondary method according to section 7.5 of ANSI/
ASHRAE 37-2009. Calculate space cooling and heating capacities using the 
refrigerant-enthalpy method measurements as specified in sections 7.5.4 
and 7.5.5, respectively, of the same ASHRAE Standard.

  3.12 Rounding of Space Conditioning Capacities for Reporting Purposes

    a. When reporting rated capacities, round them off as specified in 
Sec. 430.23 (for a single unit) and in 10 CFR 429.16 (for a sample).
    b. For the capacities used to perform the calculations in section 4 
of this appendix, however, round only to the nearest integer.

   3.13 Laboratory Testing to Determine Off Mode Average Power Ratings

    Voltage tolerances: As a percentage of reading, test operating 
tolerance shall be 2.0 percent and test condition tolerance shall be 1.5 
percent (see section 1.2 of this appendix for definitions of these 
tolerances).
    Conduct one of the following tests: If the central air conditioner 
or heat pump lacks a compressor crankcase heater, perform the test in 
section 3.13.1 of this appendix; if the central air conditioner or heat 
pump has a

[[Page 513]]

compressor crankcase heater that lacks controls and is not self-
regulating, perform the test in section 3.13.1 of this appendix; if the 
central air conditioner or heat pump has a crankcase heater with a fixed 
power input controlled with a thermostat that measures ambient 
temperature and whose sensing element temperature is not affected by the 
heater, perform the test in section 3.13.1 of this appendix; if the 
central air conditioner or heat pump has a compressor crankcase heater 
equipped with self-regulating control or with controls for which the 
sensing element temperature is affected by the heater, perform the test 
in section 3.13.2 of this appendix.

   3.13.1 This Test Determines the Off Mode Average Power Rating for 
Central Air Conditioners and Heat Pumps That Lack a Compressor Crankcase 
Heater, or Have a Compressor Crankcase Heating System That Can Be Tested 
Without Control of Ambient Temperature During the Test. This Test Has No 
                     Ambient Condition Requirements

    a. Test Sample Set-up and Power Measurement: For coil-only systems, 
provide a furnace or modular blower that is compatible with the system 
to serve as an interface with the thermostat (if used for the test) and 
to provide low-voltage control circuit power. Make all control circuit 
connections between the furnace (or modular blower) and the outdoor unit 
as specified by the manufacturer's installation instructions. Measure 
power supplied to both the furnace or modular blower and power supplied 
to the outdoor unit. Alternatively, provide a compatible transformer to 
supply low-voltage control circuit power, as described in section 2.2.d 
of this appendix. Measure transformer power, either supplied to the 
primary winding or supplied by the secondary winding of the transformer, 
and power supplied to the outdoor unit. For blower coil and single-
package systems, make all control circuit connections between components 
as specified by the manufacturer's installation instructions, and 
provide power and measure power supplied to all system components.
    b. Configure Controls: Configure the controls of the central air 
conditioner or heat pump so that it operates as if connected to a 
building thermostat that is set to the OFF position. Use a compatible 
building thermostat if necessary to achieve this configuration. For a 
thermostat-controlled crankcase heater with a fixed power input, bypass 
the crankcase heater thermostat if necessary to energize the heater.
    c. Measure P2x: If the unit has a crankcase heater time delay, make 
sure that time delay function is disabled or wait until delay time has 
passed. Determine the average power from non-zero value data measured 
over a 5-minute interval of the non-operating central air conditioner or 
heat pump and designate the average power as P2x, the heating season 
total off mode power.
    d. Measure Px for coil-only split systems and for blower coil split 
systems for which a furnace or a modular blower is the designated air 
mover: Disconnect all low-voltage wiring for the outdoor components and 
outdoor controls from the low-voltage transformer. Determine the average 
power from non-zero value data measured over a 5-minute interval of the 
power supplied to the (remaining) low-voltage components of the central 
air conditioner or heat pump, or low-voltage power, Px. This power 
measurement does not include line power supplied to the outdoor unit. It 
is the line power supplied to the air mover, or, if a compatible 
transformer is used instead of an air mover, it is the line power 
supplied to the transformer primary coil. If a compatible transformer is 
used instead of an air mover and power output of the low-voltage 
secondary circuit is measured, Px is zero.
    e. Calculate P2: Set the number of compressors equal to the unit's 
number of single-stage compressors plus 1.75 times the unit's number of 
compressors that are not single-stage.
    For single-package systems and blower coil split systems for which 
the designated air mover is not a furnace or modular blower, divide the 
heating season total off mode power (P2x) by the number of compressors 
to calculate P2, the heating season per-compressor off mode power. Round 
P2 to the nearest watt. The expression for calculating P2 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.042

    For coil-only split systems and blower coil split systems for which 
a furnace or a modular blower is the designated air mover, subtract the 
low-voltage power (Px) from the heating season total off mode power 
(P2x) and divide by the number of compressors to calculate P2, the 
heating season per-compressor off mode power. Round P2 to the nearest 
watt. The expression for calculating P2 is as follows:

[[Page 514]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.043

    f. Shoulder-season per-compressor off mode power, P1: If the system 
does not have a crankcase heater, has a crankcase heater without 
controls that is not self-regulating, or has a value for the crankcase 
heater turn-on temperature (as certified in the DOE Compliance 
Certification Database) that is higher than 71 [deg]F, P1 is equal to 
P2.
    Otherwise, de-energize the crankcase heater (by removing the 
thermostat bypass or otherwise disconnecting only the power supply to 
the crankcase heater) and repeat the measurement as described in section 
3.13.1.c of this appendix. Designate the measured average power as P1x, 
the shoulder season total off mode power.
    Determine the number of compressors as described in section 3.13.1.e 
of this appendix.
    For single-package systems and blower coil systems for which the 
designated air mover is not a furnace or modular blower, divide the 
shoulder season total off mode power (P1x) by the number of compressors 
to calculate P1, the shoulder season per-compressor off mode power. 
Round P1 to the nearest watt. The expression for calculating P1 is as 
follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.044

    For coil-only split systems and blower coil split systems for which 
a furnace or a modular blower is the designated air mover, subtract the 
low-voltage power (Px) from the shoulder season total off mode power 
(P1x) and divide by the number of compressors to calculate P1, the 
shoulder season per-compressor off mode power. Round P1 to the nearest 
watt. The expression for calculating P1 is as follows:

   3.13.2 This Test Determines the Off Mode Average Power Rating for 
 Central Air Conditioners and Heat Pumps for Which Ambient Temperature 
          Can Affect the Measurement of Crankcase Heater Power

    a. Test Sample Set-up and Power Measurement: Set up the test and 
measurement as described in section 3.13.1.a of this appendix.
    b. Configure Controls: Position a temperature sensor to measure the 
outdoor dry-bulb temperature in the air between 2 and 6 inches from the 
crankcase heater control temperature sensor or, if no such temperature 
sensor exists, position it in the air between 2 and 6 inches from the 
crankcase heater. Utilize the temperature measurements from this sensor 
for this portion of the test procedure. Configure the controls of the 
central air conditioner or heat pump so that it operates as if connected 
to a building thermostat that is set to the OFF position. Use a 
compatible building thermostat if necessary to achieve this 
configuration.
    Conduct the test after completion of the B, B1, or 
B2 test. Alternatively, start the test when the outdoor dry-
bulb temperature is at 82 [deg]F and the temperature of the compressor 
shell (or temperature of each compressor's shell if there is more than 
one compressor) is at least 81 [deg]F. Then adjust the outdoor 
temperature at a rate of change of no more than 20 [deg]F per hour and 
achieve an outdoor dry-bulb temperature of 72 [deg]F. Maintain this 
temperature within 2 [deg]F while making the power 
measurement, as described in section 3.13.2.c of this appendix.
    c. Measure P1x: If the unit has a crankcase heater time delay, make 
sure that time delay function is disabled or wait until delay time has 
passed. Determine the average power from non-zero value data measured 
over a 5-minute interval of the non-operating central air conditioner or 
heat pump and designate the average power as P1x, the shoulder season 
total off mode power. For units with crankcase heaters which operate 
during this part of the test and whose controls cycle or vary crankcase 
heater power over time, the test period shall consist of three complete 
crankcase heater cycles or 18 hours, whichever comes first. Designate 
the average power over the test period as P1x, the shoulder season total 
off mode power.

[[Page 515]]

    d. Reduce outdoor temperature: Approach the target outdoor dry-bulb 
temperature by adjusting the outdoor temperature at a rate of change of 
no more than 20 [deg]F per hour. This target temperature is five degrees 
Fahrenheit less than the temperature specified by the manufacturer in 
the DOE Compliance Certification Database at which the crankcase heater 
turns on. Maintain the target temperature within 2 
[deg]F while making the power measurement, as described in section 
3.13.2.e of this appendix.
    e. Measure P2x: If the unit has a crankcase heater time delay, make 
sure that time delay function is disabled or wait until delay time has 
passed. Determine the average non-zero power of the non-operating 
central air conditioner or heat pump over a 5-minute interval and 
designate it as P2x, the heating season total off mode power. For units 
with crankcase heaters whose controls cycle or vary crankcase heater 
power over time, the test period shall consist of three complete 
crankcase heater cycles or 18 hours, whichever comes first. Designate 
the average power over the test period as P2x, the heating season total 
off mode power.
    f. Measure Px for coil-only split systems and for blower coil split 
systems for which a furnace or modular blower is the designated air 
mover: Disconnect all low-voltage wiring for the outdoor components and 
outdoor controls from the low-voltage transformer. Determine the average 
power from non-zero value data measured over a 5-minute interval of the 
power supplied to the (remaining) low-voltage components of the central 
air conditioner or heat pump, or low-voltage power, Px.. This power 
measurement does not include line power supplied to the outdoor unit. It 
is the line power supplied to the air mover, or, if a compatible 
transformer is used instead of an air mover, it is the line power 
supplied to the transformer primary coil. If a compatible transformer is 
used instead of an air mover and power output of the low-voltage 
secondary circuit is measured, Px is zero.
    g. Calculate P1:
    Set the number of compressors equal to the unit's number of single-
stage compressors plus 1.75 times the unit's number of compressors that 
are not single-stage.
    For single-package systems and blower coil split systems for which 
the air mover is not a furnace or modular blower, divide the shoulder 
season total off mode power (P1x) by the number of compressors to 
calculate P1, the shoulder season per-compressor off mode power. Round 
to the nearest watt. The expression for calculating P1 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.046

    For coil-only split systems and blower coil split systems for which 
a furnace or a modular blower is the designated air mover, subtract the 
low-voltage power (Px) from the shoulder season total off mode power 
(P1x) and divide by the number of compressors to calculate P1, the 
shoulder season per-compressor off mode power. Round to the nearest 
watt. The expression for calculating P1 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.047

    h. Calculate P2:
    Determine the number of compressors as described in section 3.13.2.g 
of this appendix.
    For single-package systems and blower coil split systems for which 
the air mover is not a furnace, divide the heating season total off mode 
power (P2x) by the number of compressors to calculate P2, the heating 
season per-compressor off mode power. Round to the nearest watt. The 
expression for calculating P2 is as follows:

                            efficiency ratio,

where:
[GRAPHIC] [TIFF OMITTED] TR05JA17.051

Tj = the outdoor bin temperature, [deg]F. Outdoor 
          temperatures are grouped or ``binned.'' Use bins of 5 [deg]F 
          with the 8 cooling season bin temperatures being 67, 72, 77, 
          82, 87, 92, 97, and 102 [deg]F.
j = the bin number. For cooling season calculations, j ranges from 1 to 
          8.

    Additionally, for sections 4.1.2, 4.1.3, and 4.1.4 of this appendix, 
use a building cooling load, BL(Tj). When referenced, 
evaluate BL(Tj) for cooling using,

    Blower Capacity Modulation Correlates With the Outdoor Dry Bulb 
                               Temperature

    The manufacturer must provide information on how the indoor air 
volume rate or the indoor blower speed varies over the outdoor 
temperature range of 67 [deg]F to 102 [deg]F. Calculate SEER using 
Equation 4.1-1. Evaluate the quantity qc(Tj)/N in 
Equation 4.1-1 using,

          unit when operating at outdoor temperature, Tj,

          of the number of hours during the cooling season when the 
          outdoor temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          cooling season, dimensionless.

variable, FPc\k=1\ denotes the fan speed used during the 
required A1 and B1 tests (see section 3.2.2.1 of 
this appendix), FPck=2 denotes the fan speed used during the 
required A2 and B2 tests, and 
FPc(Tj) denotes the fan speed used by the unit 
when the outdoor temperature equals Tj. For units where 
indoor air volume rate is the primary control variable, the three 
FPc's are similarly defined only now being expressed in terms 
of air volume rates rather than fan speeds. Refer to sections 3.2.2.1, 
3.1.4 to 3.1.4.2, and 3.3 of this appendix regarding the definitions and 
calculations of Qc\k=1\(82), Qc\k=1\(95),

    c. The quantities X(Tj) and nj/N are the same 
quantities as used in Equation 4.1.2-1. Evaluate the cooling mode cyclic 
degradation factor CD\c\ as specified in section 3.5.3 of

    e. The parameters FPc\k=1\, and FPck=2, and 
FPc(Tj) are the same quantities that are used when 
evaluating Equation 4.1.2-2. Refer to sections 3.2.2.1, 3.1.4 to

Total Cooling Capacity Ratio. Calculate SEER as specified in section 
4.1.1 of this appendix.

  4.1.3 SEER Calculations for an Air Conditioner or Heat Pump Having a 
                         Two-Capacity Compressor

    Calculate SEER using Equation 4.1-1. Evaluate the space cooling 
capacity, Qc\k=1\ (Tj), and electrical power 
consumption, Ec\k=1\ (Tj), of the test unit when 
operating at low compressor capacity and outdoor temperature 
Tj using,

          capacity, Qck=2 (Tj), and electrical 
          power consumption, Eck=2 (Tj), of the 
          test unit when operating at high compressor capacity and

where Qck=2(95) and Eck=2(95) are determined from 
          the A2 test, Qck=2(82), and

          B2test, and all are calculated as specified in 
          section 3.3 of this appendix.
    The calculation of Equation 4.1-1 quantities 
qc(Tj)/N and ec(Tj)/N 
differs depending on whether the test unit would operate at low capacity 
(section 4.1.3.1 of this appendix), cycle between low and high capacity 
(section 4.1.3.2 of this appendix), or operate at high capacity 
(sections 4.1.3.3 and 4.1.3.4 of this appendix) in responding to the 
building load. For units that lock out low capacity operation at higher 
outdoor temperatures, the outdoor temperature at which the unit locks 
out must be that specified by the manufacturer in the certification 
report so that the appropriate equations are used. Use Equation 4.1-2 to 
calculate the building load, BL(Tj), for each temperature 
bin.

Ec\k=1\(Tj). Evaluate the cooling mode cyclic 
degradation factor CD\c\ as specified in section 3.5.3 of 
this appendix.

where:
e2(Tj)/N = The ratio of the electrical energy consumed by the 
          heat pump during periods of the space heating season when the 
          outdoor temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          heating season (N), W. For heat pumps having a heat comfort 
          controller, this ratio may also include electrical energy used 
          by resistive elements to maintain a minimum air delivery 
          temperature (see 4.2.5).
RH(Tj)/N = The ratio of the electrical energy used for 
          resistive space heating during periods when the outdoor 
          temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          heating season (N), W. Except as noted in section 4.2.5 of 
          this appendix, resistive space heating is modeled as being 
          used to meet that portion of the building load that the heat 
          pump does not meet because of insufficient capacity or because 
          the heat pump automatically turns off at the lowest outdoor 
          temperatures. For heat pumps having a heat comfort controller, 
          all or part of the electrical energy used by resistive heaters 
          at a particular bin temperature may be reflected in 
          eh(Tj)/N (see section 4.2.5 of this appendix).
Tj = the outdoor bin temperature, [deg]F. Outdoor 
          temperatures are ``binned'' such that calculations are only 
          performed based one temperature within the bin. Bins of 5 
          [deg]F are used.
nj/N= Fractional bin hours for the heating season; the ratio 
          of the number of hours during the heating season when the 
          outdoor temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          heating season, dimensionless. Obtain nj/N values 
          from Table 20.
j = the bin number, dimensionless.
J = for each generalized climatic region, the total number of 
          temperature bins, dimensionless. Referring to Table 20, J is 
          the highest bin number (j) having a nonzero entry for the 
          fractional bin hours for the generalized climatic region of 
          interest.
Fdef = the demand defrost credit described in section 3.9.2 
          of this appendix, dimensionless.
BL(Tj) = the building space conditioning load corresponding 
          to an outdoor temperature of Tj; the heating season 
          building load also depends on the generalized climatic 
          region's outdoor design temperature and the design heating 
          requirement, Btu/h.

Where:

TOD = the outdoor design temperature, [deg]F. An outdoor 
          design temperature is specified for each generalized climatic 
          region in Table 20.
C = 0.77, a correction factor which tends to improve the agreement 
          between calculated and measured building loads, dimensionless.
DHR = the design heating requirement (see section 1.2 of this appendix, 
          Definitions), Btu/h.

    Calculate the minimum and maximum design heating requirements for 
each generalized climatic region as follows:

where Qh\k\(47) is expressed in units of Btu/h and otherwise defined as 
follows:
    a. For a single-speed heat pump tested as per section 3.6.1 of this 
appendix, Qh\k\(47) = Qh(47), the space heating capacity determined from 
the H1 test.
    b. For a section 3.6.2 single-speed heat pump or a two-capacity heat 
pump not covered by item d, Qh\k\(47)=Qhk=2(47), the space heating 
capacity determined from the H1 or H12 test.
    c. For a variable-speed heat pump, Qh\k\(47)=Qhk=N(47), the space 
heating capacity determined from the H1N test.
    d. For two-capacity, northern heat pumps (see section 1.2 of this 
appendix, Definitions), Q\k\h(47)=Q\k=1\h(47), the space heating 
capacity determined from the H11 test.
    For all heat pumps, HSPF accounts for the heating delivered and the 
energy consumed by auxiliary resistive elements when operating below the 
balance point. This condition occurs when the building load exceeds the 
space heating capacity of the heat pump condenser. For HSPF calculations 
for all heat pumps, see either section 4.2.1, 4.2.2, 4.2.3, or 4.2.4 of 
this appendix, whichever applies.
    For heat pumps with heat comfort controllers (see section 1.2 of 
this appendix, Definitions), HSPF also accounts for resistive heating 
contributed when operating above the heat-pump-plus-comfort-controller 
balance point as a result of maintaining a minimum supply temperature. 
For heat pumps having a heat comfort controller, see section 4.2.5 of 
this appendix for the additional steps required for calculating the 
HSPF.

    The calculation of the Equation 4.2-1 quantities differ depending 
upon whether the heat pump would operate at low capacity (section

4.2.3.2 of this appendix), or operate at high capacity (sections 4.2.3.3 
and 4.2.3.4 of this appendix) in responding to the building load. For 
heat pumps that lock out low capacity operation at low outdoor 
temperatures, the outdoor temperature at which the unit locks out must 
be that specified by the manufacturer in the certification report so 
that the appropriate equations can be selected.

            4.2.5 Heat Pumps Having a Heat Comfort Controller

    Heat pumps having heat comfort controllers, when set to maintain a 
typical minimum air delivery temperature, will cause the heat pump 
condenser to operate less because of a greater contribution from the 
resistive elements. With a conventional heat pump, resistive heating is 
only initiated if the heat pump condenser cannot meet the building load 
(i.e., is delayed until a second stage call from the indoor thermostat). 
With a heat comfort controller, resistive heating can occur even though 
the heat pump condenser has adequate capacity to meet the building load 
(i.e., both on during a first stage call from the indoor thermostat). As 
a result, the outdoor temperature where the heat pump compressor no 
longer cycles (i.e., starts to run continuously), will be lower than if 
the heat pump did not have the heat comfort controller.

specified in section 4.2.1 of this appendix (i.e., Qh(Tj) = 
Qhp(Tj) and Ehp(Tj) =

    Airflow-control settings are programmed or wired control system 
configurations that control a fan to achieve discrete, differing ranges 
of airflow--often designated for performing a specific function (e.g., 
cooling, heating, or constant circulation)--without manual adjustment 
other than interaction with a user-operable control (i.e., a thermostat) 
that meets the manufacturer specifications for installed-use. For the 
purposes of this appendix, manufacturer specifications for installed-use 
are those found in the product literature shipped with the unit.
    Air sampling device is an assembly consisting of a manifold with 
several branch tubes with multiple sampling holes that draws an air 
sample from a critical location from the unit under test (e.g. indoor 
air inlet, indoor air outlet, outdoor air inlet, etc.).
    Airflow prevention device denotes a device that prevents airflow via 
natural convection by mechanical means, such as an air damper box, or by 
means of changes in duct height, such as an upturned duct.
    Aspirating psychrometer is a piece of equipment with a monitored 
airflow section that draws uniform airflow through the measurement 
section and has probes for measurement of air temperature and humidity.
    Blower coil indoor unit means an indoor unit either with an indoor 
blower housed with the coil or with a separate designated air mover such

the outdoor unit has a certified cooling capacity less than or equal to 
36,000 Btu/h; b) the indoor unit(s) is/are shipped with manufacturer-
supplied installation instructions that specify to secure the indoor 
unit only to the ceiling, within a furred-down space, or above a dropped 
ceiling of the conditioned space, with return air directly to the bottom 
of the unit without ductwork, or through the furred-down space, or 
optional insulated return air plenum that is shipped with the indoor 
unit; c) the installed height of the indoor unit is no more than 12 
inches (not including condensate drain lines) and the installed depth 
(in the direction of airflow) of the indoor unit is no more than 30 
inches; and d) supply air is discharged horizontally.
    Coefficient of Performance (COP) means the ratio of the average rate 
of space heating delivered to the average rate of electrical energy 
consumed by the heat pump. Determine these rate quantities from a single 
test or, if derived via interpolation, determine at a single set of 
operating conditions. COP is a dimensionless quantity. When determined 
for a ducted coil-only system, COP must be calculated using the default 
values for heat output and power input of a fan motor specified in 
sections 3.7 and 3.9.1 of this appendix.
    Coil-only indoor unit means an indoor unit that is distributed in 
commerce without an indoor blower or separate designated air mover. A 
coil-only indoor unit installed in the field relies on a separately 
installed furnace or a modular blower for indoor air movement.
    Coil-only system means a system that includes only (one or more) 
coil-only indoor units.

operating speed to provide a fixed air-volume-rate from a ducted system.
    Continuously recorded, when referring to a dry bulb measurement, dry 
bulb temperature used for test room control, wet bulb temperature, dew 
point temperature, or relative humidity measurements, means that the

space-cooling capacity for the same total time (ON + OFF) interval.
    Crankcase heater means any electrically powered device or mechanism 
for intentionally generating heat within and/or around the compressor 
sump volume. Crankcase heater control may be achieved using a timer or 
may be based on a change in temperature or some other measurable 
parameter, such that the crankcase heater is not required to operate 
continuously. A crankcase heater without controls operates continuously 
when the compressor is not operating.
    Cyclic Test means a test where the unit's compressor is cycled on 
and off for specific time intervals. A cyclic test provides half the 
information needed to calculate a degradation coefficient.

meets the performance requirements of section 2.5.7 of this appendix.
    Degradation coefficient (CD) means a parameter used in calculating 
the part load factor. The degradation coefficient for cooling is denoted 
by CD\c\. The degradation coefficient for heating is denoted 
by CD\h\.
    Demand-defrost control system means a system that defrosts the heat 
pump outdoor coil-only when measuring a predetermined degradation of 
performance. The heat pump's controls either:
    (1) Monitor one or more parameters that always vary with the amount 
of frost accumulated on the outdoor coil (e.g., coil to air differential 
temperature, coil differential air pressure, outdoor fan power or 
current, optical sensors) at least once for every ten minutes of 
compressor ON-time when space heating; or
    (2) Operate as a feedback system that measures the length of the 
defrost period and adjusts defrost frequency accordingly. In all cases, 
when the frost parameter(s) reaches a predetermined value, the system 
initiates a defrost. In a demand-defrost control system, defrosts are 
terminated based on monitoring a parameter(s) that indicates that frost 
has been eliminated from the coil. (Note: Systems that vary defrost 
intervals according to outdoor dry-bulb temperature are not demand-
defrost systems.) A demand-defrost control system, which otherwise meets 
the requirements, may allow time-initiated defrosts if, and only if, 
such defrosts occur after 6 hours of compressor operating time.
    Design heating requirement (DHR) predicts the space heating load of 
a residence when subjected to outdoor design conditions. Estimates for 
the minimum and maximum DHR are provided for six generalized U.S. 
climatic regions in section 4.2 of this appendix.

of the air supplied to the indoor unit is maintained low enough that no 
condensate forms on the evaporator coil.
    Ducted system means an air conditioner or heat pump that is designed 
to be permanently installed equipment and delivers conditioned air to 
the indoor space through a duct(s). The air conditioner or heat pump may 
be either a split-system or a single-package unit.

space cooling delivered to the average rate of electrical energy 
consumed by the air conditioner or heat pump. Determine these rate 
quantities from a single test or, if derived via interpolation, 
determine at a single set of operating conditions. EER is expressed in 
units of
[GRAPHIC] [TIFF OMITTED] TR05JA17.147

When determined for a ducted coil-only system, EER must include, from 
this appendix, the section 3.3 and 3.5.1 default values for the heat 
output and power input of a fan motor. The represented value of EER 
determined in accordance with appendix M1 is EER2.
    Evaporator coil means an assembly that absorbs heat from an enclosed 
space and transfers the heat to a refrigerant.

air dehumidifying, air humidifying, air circulating, and air cleaning.
    Heat pump having a heat comfort controller means a heat pump with 
controls that can regulate the operation of the electric resistance 
elements to assure that the air temperature leaving the indoor section 
does not fall below a specified temperature. Heat pumps that actively 
regulate the rate of electric resistance heating when operating below 
the balance point (as the result of a second stage call from the 
thermostat) but do not operate to maintain a minimum delivery 
temperature are not considered as having a heat comfort controller.
    Heating load factor (HLF) means the ratio having as its numerator 
the total heating delivered during a cyclic operating interval 
consisting of one ON period and one OFF period, and its denominator the 
heating capacity measured at the same test conditions used for the 
cyclic test, multiplied by the total time interval (ON plus OFF) of the 
cyclic-test.

e.g., typically, and roughly, October through April.
    Heating seasonal performance factor 2 (HSPF2) means the total space 
heating required during the heating season, expressed in Btu, divided by 
the total electrical energy consumed by the heat pump system during the 
same season, expressed in watt-hours. The HSPF2 used to evaluate 
compliance with 10 CFR 430.32(c) is based on Region IV and the sampling 
plan stated in 10 CFR 429.16(a). HSPF2 is determined in accordance with 
appendix M1.

its associated motor). A separate designated air mover that may be a 
furnace or a modular blower (as defined in appendix AA to the subpart) 
may be considered to be part of the indoor unit. A service coil is not 
an indoor unit.
    Low-static blower coil system means a ducted multi-split or multi-
head mini-split system for which all indoor units produce greater than 
0.01 in. wc. and a maximum of 0.35 in. wc. external static pressure when

response to a single indoor thermostat.
    Multiple-circuit (or multi-circuit) system means a split system that 
has one outdoor unit and that has two or more indoor units installed on 
two or more refrigeration circuits such that each refrigeration circuit 
serves a compressor and one and only one indoor unit, and refrigerant is

for heat pumps, may include a heating mode expansion device, reversing 
valve, and/or defrost controls.
    Outdoor unit manufacturer (OUM) means a manufacturer of single-
package units, outdoor units, and/or both indoor units and outdoor 
units.
    Part-load factor (PLF) means the ratio of the cyclic EER (or COP for 
heating) to the steady-state EER (or COP), where both EERs (or COPs) are 
determined based on operation at the same ambient conditions.
    Seasonal energy efficiency ratio 2 (SEER2) means the total heat 
removed from the conditioned space during the annual cooling season, 
expressed in Btu's, divided by the total electrical energy consumed by 
the central air conditioner or heat pump during the same season, 
expressed in watt-hours. SEER2 is determined in accordance with appendix 
M1.
    Service coil means an arrangement of refrigerant-to-air heat 
transfer coil(s), condensate drain pan, sheet metal or plastic parts to

in commerce solely for replacing an uncased coil or cased coil that has 
already been placed into service, and that has been labeled ``for indoor 
coil replacement only'' on the nameplate and in manufacturer technical 
and product literature. The model number for any service coil must 
include some mechanism (e.g., an additional letter or number) for 
differentiating a service coil from a coil intended for an indoor unit.
    Shoulder season means the months of the year in between those months 
that require cooling and those months that require heating, e.g.,

the full-load air volume rate certified by the manufacturer of at least 
220 scfm per rated ton of cooling.
    Split system means any central air conditioner or heat pump that has 
at least two separate assemblies that are connected with refrigerant 
piping when installed. One of these assemblies includes an indoor coil 
that exchanges heat with the indoor air to provide heating or cooling, 
while one of the others includes an outdoor coil that exchanges heat 
with the outdoor air. Split systems may be either blower coil systems or 
coil-only systems.
    Standard Air means dry air having a mass density of 0.075 lb/ft\3\.
    Steady-state test means a test where the test conditions are

is not possible, one or more of the indoor units may represent another 
indoor model family in order that all the other requirements of this 
section are met.

50 percent of the nominal cooling capacity of the outdoor unit, unless 
the nominal cooling capacity of the outdoor unit is 24,000 Btu/h or 
less;
    (iv) Operate at fan speeds consistent with manufacturer's 
specifications; and
    (v) All be subject to the same minimum external static pressure 
requirement while able to produce the same external static pressure at 
the exit of each outlet plenum when connected in a manifold 
configuration as required by the test procedure.

product literature for these conditions. If incomplete or no operating 
conditions are published, use the highest (for indoor units) or lowest 
(for outdoor units) such cooling capacity available for sale.
    Time-adaptive defrost control system is a demand-defrost control 
system that measures the length of the prior defrost period(s) and uses 
that information to automatically determine when to initiate the next 
defrost cycle.
    Time-temperature defrost control systems initiate or evaluate 
initiating a defrost cycle only when a predetermined cumulative 
compressor ON-time is obtained. This predetermined ON-time is generally 
a fixed value (e.g., 30, 45, 90 minutes) although it may vary based on 
the measured outdoor dry-bulb temperature. The ON-time counter 
accumulates if controller measurements (e.g., outdoor temperature, 
evaporator temperature) indicate that frost formation conditions are 
present, and it is reset/remains at zero at all other times. In one 
application of the control scheme, a defrost is initiated whenever the 
counter time equals the predetermined ON-time. The counter is reset when 
the defrost cycle is completed.
    In a second application of the control scheme, one or more 
parameters are measured (e.g., air and/or refrigerant temperatures) at 
the predetermined, cumulative, compressor ON-time. A defrost is 
initiated only if the measured parameter(s) falls within a predetermined 
range. The ON-time counter is reset regardless of whether or not a 
defrost is initiated. If systems of this second type use cumulative ON-
time intervals of 10 minutes or less, then the heat pump may qualify as 
having a demand defrost control system (see definition).
    Triple-capacity, northern heat pump means a heat pump that provides 
two stages of cooling and three stages of heating. The two common stages 
for both the cooling and heating modes are the low capacity stage and 
the high capacity stage. The additional heating mode stage is the 
booster capacity stage, which offers the highest heating capacity output 
for a given set of ambient operating conditions.
    Triple-split system means a split system that is composed of three 
separate assemblies: An outdoor fan coil section, a blower coil indoor 
unit, and an indoor compressor section.
    Two-capacity (or two-stage) compressor system means a central air 
conditioner or heat pump that has a compressor or a group of compressors 
operating with only two stages of capacity. For such systems, low 
capacity means the compressor(s) operating at low stage, or at low load 
test conditions. The low compressor stage that operates for heating mode 
tests may be the same or different from the low compressor stage that 
operates for cooling mode tests. For such systems, high capacity means 
the compressor(s) operating at high stage, or at full load test 
conditions.
    Two-capacity, northern heat pump means a heat pump that has a 
factory or field-selectable lock-out feature to prevent space cooling at 
high-capacity. Two-capacity heat pumps having this feature will 
typically have two sets of ratings, one with the feature disabled and 
one with the feature enabled. The heat pump is a two-capacity northern 
heat pump only when this feature is enabled at all times. The certified 
indoor coil model number must reflect whether the ratings pertain to the 
lockout enabled option via the inclusion of an extra identifier, such as 
``+LO''. When testing as a two-capacity, northern heat pump, the lockout 
feature must remain enabled for all tests.
    Uncased coil means a coil-only indoor unit without external 
cabinetry.
    Variable refrigerant flow (VRF) system means a multi-split system 
with at least three compressor capacity stages, distributing refrigerant 
through a piping network to multiple indoor blower coil units each 
capable of individual zone temperature control, through proprietary zone 
temperature control devices and a common communications network. Note: 
Single-phase VRF systems less than 65,000 Btu/h are central air 
conditioners and central air conditioning heat pumps.
    Variable-speed compressor system means a central air conditioner or 
heat pump that has a compressor that uses a variable-speed drive to vary 
the compressor speed to achieve variable capacities. Wall-mount blower 
coil system means a split system air conditioner or heat pump for which:
    (a) The outdoor unit has a certified cooling capacity less than or 
equal to 36,000 Btu/h;
    (b) The indoor unit(s) is/are shipped with manufacturer-supplied 
installation instructions that specify mounting only by:
    (1) Securing the back side of the unit to a wall within the 
conditioned space, or
    (2) Securing the unit to adjacent wall studs or in an enclosure, 
such as a closet, such that the indoor unit's front face is flush with a 
wall in the conditioned space;
    (c) Has front air return without ductwork and is not capable of 
horizontal air discharge; and
    (d) Has a height no more than 45 inches, a depth (perpendicular to 
the wall) no more than 22 inches (including tubing connections), and a 
width no more than 24 inches (parallel to the wall).
    Wet-coil test means a test conducted at test conditions that 
typically cause water vapor to condense on the test unit evaporator 
coil.

                    2 Testing Overview and Conditions

    (A) Test VRF systems using AHRI 1230-2010 (incorporated by 
reference, see Sec. 430.3) and appendix M. Where AHRI 1230-2010 refers 
to

[[Page 552]]

the appendix C therein substitute the provisions of this appendix. In 
cases where there is a conflict, the language of the test procedure in 
this appendix takes precedence over AHRI 1230-2010.
    For definitions use section 1 of appendix M and section 3 of AHRI 
1230-2010. For rounding requirements, refer to Sec. 430.23(m). For 
determination of certified ratings, refer to Sec. 429.16 of this 
chapter.
    For test room requirements, refer to section 2.1 of this appendix. 
For test unit installation requirements refer to sections 2.2.a, 2.2.b, 
2.2.c, 2.2.1, 2.2.2, 2.2.3.a, 2.2.3.c, 2.2.4, 2.2.5, and 2.4 to 2.12 of 
this appendix, and sections 5.1.3 and 5.1.4 of AHRI 1230-2010. The 
``manufacturer's published instructions,'' as stated in section 8.2 of 
ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3) and 
``manufacturer's installation instructions'' discussed in this appendix 
mean the manufacturer's installation instructions that come packaged 
with or appear in the labels applied to the unit. This does not include 
online manuals. Installation instructions that appear in the labels 
applied to the unit take precedence over installation instructions that 
are shipped with the unit.
    For general requirements for the test procedure, refer to section 
3.1 of this appendix, except for sections 3.1.3 and 3.1.4, which are 
requirements for indoor air volume and outdoor air volume. For indoor 
air volume and outdoor air volume requirements, refer instead to section 
6.1.5 (except where section 6.1.5 refers to Table 8, refer instead to 
Table 4 of this appendix) and 6.1.6 of AHRI 1230-2010.
    For the test method, refer to sections 3.3 to 3.5 and 3.7 to 3.13 of 
this appendix. For cooling mode and heating mode test conditions, refer 
to section 6.2 of AHRI 1230-2010. For calculations of seasonal 
performance descriptors, refer to section 4 of this appendix.
    (B) For systems other than VRF, only a subset of the sections listed 
in this test procedure apply when testing and determining represented 
values for a particular unit. Table 1 shows the sections of the test 
procedure that apply to each system. This table is meant to assist 
manufacturers in finding the appropriate sections of the test procedure; 
the appendix sections rather than the table provide the specific 
requirements for testing, and given the varied nature of available 
units, manufacturers are responsible for determining which sections 
apply to each unit tested based on the model characteristics. To use 
this table, first refer to the sections listed under ``all units''. Then 
refer to additional requirements based on:
    (1) System configuration(s),
    (2) The compressor staging or modulation capability, and
    (3) Any special features.
    Testing requirements for space-constrained products do not differ 
from similar equipment that is not space-constrained and thus are not 
listed separately in this table. Air conditioners and heat pumps are not 
listed separately in this table, but heating procedures and calculations 
apply only to heat pumps.

                       2.1 Test Room Requirements.

    a. Test using two side-by-side rooms: An indoor test room and an 
outdoor test room. For multiple-split, single-zone-multi-coil or multi-
circuit air conditioners and heat pumps, however, use as many indoor 
test rooms as needed to accommodate the total number of indoor units. 
These rooms must

[[Page 556]]

comply with the requirements specified in sections 8.1.2 and 8.1.3 of 
ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3).
    b. Inside these test rooms, use artificial loads during cyclic tests 
and frost accumulation tests, if needed, to produce stabilized room air 
temperatures. For one room, select an electric resistance heater(s) 
having a heating capacity that is approximately equal to the heating 
capacity of the test unit's condenser. For the second room, select a 
heater(s) having a capacity that is close to the sensible cooling 
capacity of the test unit's evaporator. Cycle the heater located in the 
same room as the test unit evaporator coil ON and OFF when the test unit 
cycles ON and OFF. Cycle the heater located in the same room as the test 
unit condensing coil ON and OFF when the test unit cycles OFF and ON.

                2.2 Test Unit Installation Requirements.

    a. Install the unit according to section 8.2 of ANSI/ASHRAE 37-2009

section 6.1.3.5 of AHRI 210/240-2008 (incorporated by reference, see 
Sec. 430.3). For the vapor refrigerant line(s), use the insulation 
included with the unit; if no insulation is provided, use insulation 
meeting the specifications for the insulation in the installation 
instructions included with the unit by the manufacturer; if no 
insulation is included with the unit and the installation instructions 
do not contain provisions for insulating the line(s), fully insulate the 
vapor refrigerant line(s) with vapor proof insulation having an inside 
diameter that matches the refrigerant tubing and a nominal thickness of 
at least 0.5 inches. For the liquid refrigerant line(s), use the 
insulation included with the unit; if no insulation is provided, use 
insulation meeting the specifications for the insulation in the 
installation instructions included with the unit by the manufacturer; if 
no insulation is included with the unit and the installation 
instructions do not contain provisions for insulating the line(s), leave 
the liquid refrigerant line(s) exposed to the air for air conditioners 
and heat pumps that heat and cool; or, for heating-only heat pumps, 
insulate the liquid refrigerant line(s) with insulation having an inside 
diameter that matches the refrigerant tubing and a nominal thickness of 
at least 0.5 inches. However, these requirements do not take priority 
over instructions for application of insulation for the purpose of 
improving refrigerant temperature measurement accuracy as required by 
sections 2.10.2 and 2.10.3 of this appendix. Insulation must be the same 
for the cooling and heating tests.
    (2) When testing split systems, if the indoor unit does not ship 
with a cooling mode expansion device, test the system using the device 
as specified in the installation instructions provided with the indoor 
unit. If none is specified, test the system using a fixed orifice or 
piston type expansion device that is sized appropriately for the system.
    (3) When testing triple-split systems (see section 1.2 of this 
appendix, Definitions), use the tubing length specified in section 
6.1.3.5 of AHRI 210/240-2008 (incorporated by reference, see Sec. 
430.3) to connect the outdoor coil, indoor compressor section, and 
indoor coil while still meeting the requirement of exposing 10 feet of 
the tubing to outside conditions;
    (4) When testing split systems having multiple indoor coils, connect 
each indoor blower coil unit to the outdoor unit using:
    (a) 25 feet of tubing, or
    (b) Tubing furnished by the manufacturer, whichever is longer.
    (5) When testing split systems having multiple indoor coils, expose 
at least 10 feet of the system interconnection tubing to the outside 
conditions. If they are needed to make a secondary measurement of 
capacity or for verification of refrigerant charge, install refrigerant 
pressure measuring instruments as described in section 8.2.5 of ANSI/
ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3). Section 
2.10 of this appendix specifies which secondary methods require 
refrigerant pressure measurements and section 2.2.5.5 of this appendix 
discusses use of pressure measurements to verify charge. At a minimum, 
insulate the low-pressure line(s) of a split system with insulation 
having an inside diameter that matches the refrigerant tubing and a 
nominal thickness of 0.5 inch.
    b. For units designed for both horizontal and vertical installation 
or for both up-flow and down-flow vertical installations, use the 
orientation for testing specified by the manufacturer in the 
certification report. Conduct testing with the following installed:
    (1) The most restrictive filter(s);
    (2) Supplementary heating coils; and
    (3) Other equipment specified as part of the unit, including all 
hardware used by a heat comfort controller if so equipped (see section 1 
of this appendix, Definitions). For small-duct, high-velocity systems, 
configure all balance dampers or restrictor devices on or inside the 
unit to fully open or lowest restriction.
    c. Testing a ducted unit without having an indoor air filter 
installed is permissible as long as the minimum external static pressure 
requirement is adjusted as stated in Table 4, note 3 (see section 3.1.4 
of this appendix). Except as noted in section 3.1.10 of this appendix, 
prevent the indoor air supplementary heating coils from operating during 
all tests. For uncased coils, create an enclosure using 1 inch 
fiberglass foil-faced ductboard having a nominal density of 6

[[Page 557]]

pounds per cubic foot. Or alternatively, construct an enclosure using 
sheet metal or a similar material and insulating material having a 
thermal resistance (``R'' value) between 4 and 6 hr [middot] ft\2\ 
[middot] [deg]F/Btu. Size the enclosure and seal between the coil and/or 
drainage pan and the interior of the enclosure as specified in 
installation instructions shipped with the unit. Also seal between the 
plenum and inlet and outlet ducts.
    d. When testing a coil-only system, install a toroidal-type 
transformer to power the system's low-voltage components, complying with 
any additional requirements for the transformer mentioned in the 
installation manuals included with the unit by the system manufacturer. 
If the installation manuals do not provide specifications for the 
transformer, use a transformer having the following features:
    (1) A nominal volt-amp rating such that the transformer is loaded 
between 25 and 90 percent of this rating for the highest level of power 
measured during the off mode test (section 3.13 of this appendix);
    (2) Designed to operate with a primary input of 230 V, single phase, 
60 Hz; and
    (3) That provides an output voltage that is within the specified 
range for each low-voltage component. Include the power consumption of 
the components connected to the transformer as part of the total system 
power consumption during the off mode tests; do not include the power 
consumed by the transformer when no load is connected to it.
    e. Test an outdoor unit with no match (i.e., that is not distributed 
in commerce with any indoor units) using a coil-only indoor unit with a 
single cooling air volume rate whose coil has:
    (1) Round tubes of outer diameter no less than 0.375 inches, and
    (2) A normalized gross indoor fin surface (NGIFS) no greater than 
1.0 square inch per British thermal unit per hour (sq. in./Btu/hr). 
NGIFS is calculated as follows:
    NGIFS = 2 x Lf x Wf x Nf / Qc(95)
where,

Lf = Indoor coil fin length in inches, also height of the 
          coil transverse to the tubes.

Wf = Indoor coil fin width in inches, also depth of the coil.

Nf = Number of fins.

Qc(95) = the measured space cooling capacity of the tested outdoor unit/
          indoor unit combination as determined from the A2 
          or A Test whichever applies, Btu/h.

    f. If the outdoor unit or the outdoor portion of a single-package 
unit has a drain pan heater to prevent freezing of defrost water, 
energize the heater, subject to control to de-energize it when not 
needed by the heater's thermostat or the unit's control system, for all 
tests.
    g. If pressure measurement devices are connected to a cooling/
heating heat pump refrigerant circuit, the refrigerant charge 
Mt that could potentially transfer out of the connected 
pressure measurement systems (transducers, gauges, connections, and 
lines) between operating modes must be less than 2 percent of the 
factory refrigerant charge listed on the nameplate of the outdoor unit. 
If the outdoor unit nameplate has no listed refrigerant charge, or the 
heat pump is shipped without a refrigerant charge, use a factory 
refrigerant charge equal to 30 ounces per ton of certified cooling 
capacity. Use Equation 2.2-1 to calculate Mt for heat pumps 
that have a single expansion device located in the outdoor unit to serve 
each indoor unit, and use Equation 2.2-2 to calculate Mt for 
heat pumps that have two expansion devices per indoor unit.

where:

Vi (i=2,3,4 . . .) = the internal volume of the pressure 
          measurement system (pressure lines, fittings, and gauge and/or 
          transducer) at the location i (as indicated in Table 2), 
          (cubic inches)

fi (i=5,6) = 0 if the pressure measurement system is pitched 
          upwards from the pressure tap location to the gauge or 
          transducer, 1 if it is not.

r = the density associated with liquid refrigerant at 100 [deg]F bubble 
          point conditions (ounces per cubic inch)

    Calculate the internal volume of each pressure measurement system 
using internal volume reported for pressure transducers and gauges in 
product literature, if available. If such information is not available, 
use the value of 0.1 cubic inch internal volume for each pressure 
transducer, and 0.2 cubic inches for each pressure gauge.
    In addition, for heat pumps that have a single expansion device 
located in the outdoor unit to serve each indoor unit, the internal 
volume of the pressure system at location 2 (as indicated in Table 2) 
must be no more than 1 cubic inches. Once the pressure measurement lines 
are set up, no change should be made until all tests are finished.

                     2.2.1 Defrost Control Settings

    Set heat pump defrost controls at the normal settings which most 
typify those encountered in generalized climatic region IV. (Refer to 
Figure 1 and Table 20 of section 4.2 of this appendix for information on 
region IV.) For heat pumps that use a time-adaptive defrost control 
system (see section 1.2 of this appendix, Definitions), the manufacturer 
must specify in the certification report the frosting interval to be 
used during frost accumulation tests and provide the procedure for 
manually initiating the defrost at the specified time.

2.2.2 Special Requirements for Units Having a Multiple-Speed Outdoor Fan

    Configure the multiple-speed outdoor fan according to the 
installation manual included with the unit by the manufacturer, and 
thereafter, leave it unchanged for all tests. The controls of the unit 
must regulate the operation of the outdoor fan during all lab tests 
except dry coil cooling mode tests. For dry coil cooling mode tests, the 
outdoor fan must operate at the same speed used during the required wet 
coil test conducted at the same outdoor test conditions.

  2.2.3 Special Requirements for Multi-Split Air Conditioners and Heat 
   Pumps and Ducted Systems Using a Single Indoor Section Containing 
 Multiple Indoor Blowers That Would Normally Operate Using Two or More 
                           Indoor Thermostats

    Because these systems will have more than one indoor blower and 
possibly multiple outdoor fans and compressor systems, references in 
this test procedure to a singular indoor blower, outdoor fan, and/or 
compressor means all indoor blowers, all outdoor fans, and all 
compressor systems that are energized during the test.
    a. Additional requirements for multi-split air conditioners and heat 
pumps. For any test where the system is operated at part load (i.e., one 
or more compressors ``off'', operating at the intermediate or minimum 
compressor speed, or at low compressor capacity), the manufacturer must 
designate in the certification report the indoor coil(s) that are not 
providing heating or cooling during the test. For variable-speed 
systems, the manufacturer must designate in the certification report at 
least one indoor unit that is not providing heating or cooling for all 
tests conducted at minimum compressor speed. For all other part-load 
tests, the manufacturer must choose to turn off zero, one, two, or more 
indoor units. The chosen configuration must remain unchanged for all 
tests conducted at the same compressor speed/capacity. For any indoor 
coil that is not providing heating or cooling during a test, cease 
forced airflow through this indoor coil and block its outlet duct.
    b. Additional requirements for ducted split systems with a single 
indoor unit containing multiple indoor blowers (or for single-package 
units with an indoor section containing multiple indoor blowers) where 
the indoor blowers are designed to cycle on and off independently of one 
another and are not controlled such that all indoor blowers are 
modulated to always operate at the same air volume rate or speed. For 
any test where the system is operated at its lowest capacity--i.e., the 
lowest total air volume rate allowed when operating the single-speed 
compressor or when operating at low compressor capacity--turn off indoor 
blowers accounting for at least one-third of the full-load air volume 
rate unless prevented by the controls of the unit. In such cases, turn 
off as many indoor blowers as permitted by the unit's controls. Where 
more than one option exists for meeting this ``off'' requirement, the 
manufacturer must indicate in its certification report which indoor 
blower(s) are turned off. The chosen configuration shall remain 
unchanged for all tests conducted at the same lowest capacity 
configuration. For any indoor coil turned off during a test, cease 
forced airflow through any outlet duct connected to a switched-off 
indoor blower.
    c. For test setups where the laboratory's physical limitations 
require use of more than the required line length of 25 feet as listed 
in section 2.2.a.(4) of this appendix, then the actual refrigerant line 
length used by the laboratory may exceed the required length and the 
refrigerant line length correction factors in Table 4 of AHRI 1230-2010 
are applied to the cooling capacity measured for each cooling mode test.

2.2.4 Wet-Bulb Temperature Requirements for the Air Entering the Indoor 
                            and Outdoor Coils

                       2.2.4.1 Cooling Mode Tests

    For wet-coil cooling mode tests, regulate the water vapor content of 
the air entering the indoor unit so that the wet-bulb temperature is as 
listed in Tables 5 to 8. As noted in these same tables, achieve a wet-
bulb temperature during dry-coil cooling mode tests that results in no 
condensate forming on the indoor coil. Controlling the water vapor 
content of the air entering the outdoor side of the unit is not required 
for cooling mode tests except when testing:
    (1) Units that reject condensate to the outdoor coil during wet coil 
tests. Tables 5-8 list the applicable wet-bulb temperatures.
    (2) Single-package units where all or part of the indoor section is 
located in the outdoor test room. The average dew point temperature of 
the air entering the outdoor coil during wet coil tests must be within 
3.0 [deg]F of the average dew point temperature of 
the air entering the indoor coil over the 30-minute data collection 
interval described in section 3.3 of this appendix. For dry coil tests 
on such units, it may be necessary to limit the moisture content of the 
air entering the outdoor coil of the unit to meet the requirements of 
section 3.4 of this appendix.

                       2.2.4.2 Heating Mode Tests

    For heating mode tests, regulate the water vapor content of the air 
entering the outdoor unit to the applicable wet-bulb temperature listed 
in Tables 12 to 15. The wet-bulb temperature entering the indoor side of 
the heat pump must not exceed 60 [deg]F. Additionally, if the Outdoor 
Air Enthalpy test method (section 2.10.1 of this appendix) is used while 
testing a single-package heat pump where all or part of the outdoor 
section is located in the indoor test room, adjust the wet-bulb 
temperature for the air entering the indoor side to yield an indoor-side 
dew point temperature that is as close as reasonably possible to the dew 
point temperature of the outdoor-side entering air.

           2.2.5 Additional Refrigerant Charging Requirements

                2.2.5.1 Instructions to Use for Charging

    a. Where the manufacturer's installation instructions contain two 
sets of refrigerant charging criteria, one for field installations and 
one for lab testing, use the field installation criteria.
    b. For systems consisting of an outdoor unit manufacturer's outdoor 
section and indoor section with differing charging procedures, adjust 
the refrigerant charge per the outdoor installation instructions.
    c. For systems consisting of an outdoor unit manufacturer's outdoor 
unit and an independent coil manufacturer's indoor unit with differing 
charging procedures, adjust the refrigerant charge per the indoor unit's 
installation instructions. If instructions are provided only with the 
outdoor unit or are provided only with an independent coil 
manufacturer's indoor unit, then use the provided instructions.

                   2.2.5.2 Test(s) to Use for Charging

    a. Use the tests or operating conditions specified in the 
manufacturer's installation instructions for charging. The 
manufacturer's installation instructions may specify use of tests other 
than the A or A2 test for charging, but, unless the unit is a 
heating-only heat pump, determine the air volume rate by the A or 
A2 test as specified in section 3.1 of this appendix.
    b. If the manufacturer's installation instructions do not specify a 
test or operating conditions for charging or there are no manufacturer's 
instructions, use the following test(s):
    (1) For air conditioners or cooling and heating heat pumps, use the 
A or A2 test.
    (2) For cooling and heating heat pumps that do not operate in the H1 
or H12 test (e.g. due to shut down by the unit limiting 
devices) when tested using the charge determined at the A or 
A2 test, and for heating-only heat pumps, use the H1 or 
H12 test.

            2.2.5.3 Parameters to Set and Their Target Values

    a. Consult the manufacturer's installation instructions regarding 
which parameters (e.g., superheat) to set and their target values. If 
the instructions provide ranges of values, select target values equal to 
the midpoints of the provided ranges.
    b. In the event of conflicting information between charging 
instructions (i.e., multiple conditions given for charge adjustment 
where all conditions specified cannot be met), follow the following 
hierarchy.
    (1) For fixed orifice systems:
    (i) Superheat
    (ii) High side pressure or corresponding saturation or dew-point 
temperature
    (iii) Low side pressure or corresponding saturation or dew-point 
temperature
    (iv) Low side temperature
    (v) High side temperature
    (vi) Charge weight
    (2) For expansion valve systems:
    (i) Subcooling
    (ii) High side pressure or corresponding saturation or dew-point 
temperature
    (iii) Low side pressure or corresponding saturation or dew-point 
temperature

[[Page 560]]

    (iv) Approach temperature (difference between temperature of liquid 
leaving condenser and condenser average inlet air temperature)
    (v) Charge weight
    c. If there are no installation instructions and/or they do not 
provide parameters and target values, set superheat to a target value of 
12 [deg]F for fixed orifice systems or set subcooling to a target value 
of 10 [deg]F for expansion valve systems.

                       2.2.5.4 Charging Tolerances

    a. If the manufacturer's installation instructions specify 
tolerances on target values for the charging parameters, set the values 
within these tolerances.
    b. Otherwise, set parameter values within the following test 
condition tolerances for the different charging parameters:
    11. Superheat:  2.0 [deg]F
    12. Subcooling:  2.0 [deg]F
    13. High side pressure or corresponding saturation or dew point 
temperature:  4.0 psi or  
1.0 [deg]F
    14. Low side pressure or corresponding saturation or dew point 
temperature:  2.0 psi or  
0.8 [deg]F
    15. High side temperature:  2.0 [deg]F
    16. Low side temperature:  2.0 [deg]F
    17. Approach temperature:  1.0 [deg]F
    18. Charge weight:  2.0 ounce

                  2.2.5.5 Special Charging Instructions

    a. Cooling and Heating Heat Pumps
    If, using the initial charge set in the A or A2 test, the 
conditions are not within the range specified in manufacturer's 
installation instructions for the H1 or H12 test, make as 
small as possible an adjustment to obtain conditions for this test in 
the specified range. After this adjustment, recheck conditions in the A 
or A2 test to confirm that they are still within the 
specified range for the A or A2 test.

                        b. Single-Package Systems

    i. Unless otherwise directed by the manufacturer's installation 
instructions, install one or more refrigerant line pressure gauges 
during the setup of the unit, located depending on the parameters used 
to verify or set charge, as described:
    (1) Install a pressure gauge at the location of the service valve on 
the liquid line if charging is on the basis of subcooling, or high side 
pressure or corresponding saturation or dew point temperature;
    (2) Install a pressure gauge at the location of the service valve on 
the suction line if charging is on the basis of superheat, or low side 
pressure or corresponding saturation or dew point temperature.
    ii. Use methods for installing pressure gauge(s) at the required 
location(s) as indicated in manufacturer's instructions if specified.

           2.2.5.6 Near-Azeotropic and Zeotropic Refrigerants

    Perform charging of near-azeotropic and zeotropic refrigerants only 
with refrigerant in the liquid state.

               2.2.5.7 Adjustment of Charge Between Tests

    After charging the system as described in this test procedure, use 
the set refrigerant charge for all tests used to determine performance. 
Do not adjust the refrigerant charge at any point during testing. If 
measurements indicate that refrigerant charge has leaked during the 
test, repair the refrigerant leak, repeat any necessary set-up steps, 
and repeat all tests.

                       2.3 Indoor Air Volume Rates

    If a unit's controls allow for overspeeding the indoor blower 
(usually on a temporary basis), take the necessary steps to prevent 
overspeeding during all tests.

                           2.3.1 Cooling Tests

    a. Set indoor blower airflow-control settings (e.g., fan motor pin 
settings, fan motor speed) according to the requirements that are 
specified in section 3.1.4 of this appendix.
    b. Express the Cooling full-load air volume rate, the Cooling 
Minimum Air Volume Rate, and the Cooling Intermediate Air Volume Rate in 
terms of standard air.

                           2.3.2 Heating Tests

    a. Set indoor blower airflow-control settings (e.g., fan motor pin 
settings, fan motor speed) according to the requirements that are 
specified in section 3.1.4 of this appendix.
    b. Express the heating full-load air volume rate, the heating 
minimum air volume rate, the heating intermediate air volume rate, and 
the heating nominal air volume rate in terms of standard air.

            2.4 Indoor Coil Inlet and Outlet Duct Connections

    Insulate and/or construct the outlet plenum as described in section 
2.4.1 of this appendix and, if installed, the inlet plenum described in 
section 2.4.2 of this appendix with thermal insulation having a nominal 
overall resistance (R-value) of at least 19 hr[middot]ft\2\ [deg]F/Btu.

                 2.4.1 Outlet Plenum for the Indoor Unit

    a. Attach a plenum to the outlet of the indoor coil. (Note: For some 
packaged systems, the indoor coil may be located in the outdoor test 
room.)
    b. For systems having multiple indoor coils, or multiple indoor 
blowers within a single indoor section, attach a plenum to

[[Page 561]]

each indoor coil or indoor blower outlet. In order to reduce the number 
of required airflow measurement apparatuses (section 2.6 of this 
appendix), each such apparatus may serve multiple outlet plenums 
connected to a single common duct leading to the apparatus. More than 
one indoor test room may be used, which may use one or more common ducts 
leading to one or more airflow measurement apparatuses within each test 
room that contains multiple indoor coils. At the plane where each plenum 
enters a common duct, install an adjustable airflow damper and use it to 
equalize the static pressure in each plenum. The outlet air temperature 
grid(s) (section 2.5.4 of this appendix) and airflow measuring apparatus 
shall be located downstream of the inlet(s) to the common duct(s). For 
multiple-circuit (or multi-circuit) systems for which each indoor coil 
outlet is measured separately and its outlet plenum is not connected to 
a common duct connecting multiple outlet plenums, install the outlet air 
temperature grid and airflow measuring apparatus at each outlet plenum.
    c. For small-duct, high-velocity systems, install an outlet plenum 
that has a diameter that is equal to or less than the value listed in 
Table 3. The limit depends only on the Cooling full-load air volume rate 
(see section 3.1.4.1.1 of this appendix) and is effective regardless of 
the flange dimensions on the outlet of the unit (or an air supply plenum 
adapter accessory, if installed in accordance with the manufacturer's 
installation instructions).
    d. Add a static pressure tap to each face of the (each) outlet 
plenum, if rectangular, or at four evenly distributed locations along 
the circumference of an oval or round plenum. Create a manifold that 
connects the four static pressure taps. Figure 9 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3) shows allowed options for 
the manifold configuration. The cross-sectional dimensions of plenum 
must be equal to the dimensions of the indoor unit outlet. See Figures 
7a, 7b, and 7c of ANSI/ASHRAE 37-2009 for the minimum length of the 
(each) outlet plenum and the locations for adding the static pressure 
taps for ducted blower coil indoor units and single-package systems. See 
Figure 8 of ANSI/ASHRAE 37-2009 for coil-only indoor units.

* If the outlet plenum is rectangular, calculate its equivalent diameter
  using (4A/P,) where A is the cross-sectional area and P is the
  perimeter of the rectangular plenum, and compare it to the listed
  maximum diameter.

                 2.4.2 Inlet Plenum for the Indoor Unit

    Install an inlet plenum when testing a coil-only indoor unit, a 
ducted blower coil indoor unit, or a single-package system. See Figures 
7b and 7c of ANSI/ASHRAE 37-2009 for cross-sectional dimensions, the 
minimum length of the inlet plenum, and the locations of the static-
pressure taps for ducted blower coil indoor units and single-package 
systems. See Figure 8 of ANSI/ASHRAE 37-2009 for coil-only indoor units. 
The inlet plenum duct size shall equal the size of the inlet opening of 
the air-handling (blower coil) unit or furnace. For a ducted blower coil 
indoor unit the set up may omit the inlet plenum if an inlet airflow 
prevention device is installed with a straight internally unobstructed 
duct on its outlet end with a minimum length equal to 1.5 times the 
square root of the cross-sectional area of the indoor unit inlet. See 
section 2.1.5.2 of this appendix for requirements for the locations of 
static pressure taps built into the inlet airflow prevention device. For 
all of these arrangements, make a manifold that connects the four 
static-pressure taps using one of the three configurations specified in 
section 2.4.1.d. of this appendix. Never use an inlet plenum when 
testing a non-ducted system.

    2.5 Indoor Coil Air Property Measurements and Airflow Prevention 
                                Devices.

    Follow instructions for indoor coil air property measurements as 
described in section 2.14 of this appendix, unless otherwise instructed 
in this section.
    a. Measure the dry-bulb temperature and water vapor content of the 
air entering and leaving the indoor coil. If needed, use an air sampling 
device to divert air to a sensor(s) that measures the water vapor 
content of the air. See section 5.3 of ANSI/ASHRAE 41.1-2013 
(incorporated by reference, see Sec. 430.3) for guidance on 
constructing an air sampling device. No part of the air sampling device 
or the tubing transferring the sampled air to the sensor must be within 
two inches of the test chamber floor, and the transfer tubing must be 
insulated. The sampling device may also be used for measurement of dry 
bulb temperature by transferring the sampled air to a remotely located

[[Page 562]]

sensor(s). The air sampling device and the remotely located temperature 
sensor(s) may be used to determine the entering air dry bulb temperature 
during any test. The air sampling device and the remotely located 
sensor(s) may be used to determine the leaving air dry bulb temperature 
for all tests except:
    (1) Cyclic tests; and
    (2) Frost accumulation tests.
    b. Install grids of temperature sensors to measure dry bulb 
temperatures of both the entering and leaving airstreams of the indoor 
unit. These grids of dry bulb temperature sensors may be used to measure 
average dry bulb temperature entering and leaving the indoor unit in all 
cases (as an alternative to the dry bulb sensor measuring the sampled 
air). The leaving airstream grid is required for measurement of average 
dry bulb temperature leaving the indoor unit for cyclic tests and frost 
accumulation tests. The grids are also required to measure the air 
temperature distribution of the entering and leaving airstreams as 
described in sections 3.1.8 of this appendix. Two such grids may be 
applied as a thermopile, to directly obtain the average temperature 
difference rather than directly measuring both entering and leaving 
average temperatures.
    c. Use of airflow prevention devices. Use an inlet and outlet air 
damper box, or use an inlet upturned duct and an outlet air damper box 
when conducting one or both of the cyclic tests listed in sections 3.2 
and 3.6 of this appendix on ducted systems. If not conducting any cyclic 
tests, an outlet air damper box is required when testing ducted and non-
ducted heat pumps that cycle off the indoor blower during defrost cycles 
and there is no other means for preventing natural or forced convection 
through the indoor unit when the indoor blower is off. Never use an 
inlet damper box or an inlet upturned duct when testing non-ducted 
indoor units. An inlet upturned duct is a length of ductwork installed 
upstream from the inlet such that the indoor duct inlet opening, facing 
upwards, is sufficiently high to prevent natural convection transfer out 
of the duct. If an inlet upturned duct is used, install a dry bulb 
temperature sensor near the inlet opening of the indoor duct at a 
centerline location not higher than the lowest elevation of the duct 
edges at the inlet, and ensure that any pair of 5-minute averages of the 
dry bulb temperature at this location, measured at least every minute 
during the compressor OFF period of the cyclic test, do not differ by 
more than 1.0 [deg]F.

2.5.1 Test Set-Up on the Inlet Side of the Indoor Coil: for Cases Where 
            the Inlet Airflow Prevention Device is Installed

    a. Install an airflow prevention device as specified in section 
2.5.1.1 or 2.5.1.2 of this appendix, whichever applies.
    b. For an inlet damper box, locate the grid of entering air dry-bulb 
temperature sensors, if used, and the air sampling device, or the sensor 
used to measure the water vapor content of the inlet air, at a location 
immediately upstream of the damper box inlet. For an inlet upturned 
duct, locate the grid of entering air dry-bulb temperature sensors, if 
used, and the air sampling device, or the sensor used to measure the 
water vapor content of the inlet air, at a location at least one foot 
downstream from the beginning of the insulated portion of the duct but 
before the static pressure measurement.
    2.5.1.1 If the section 2.4.2 inlet plenum is installed, construct 
the airflow prevention device having a cross-sectional flow area equal 
to or greater than the flow area of the inlet plenum. Install the 
airflow prevention device upstream of the inlet plenum and construct 
ductwork connecting it to the inlet plenum. If needed, use an adaptor 
plate or a transition duct section to connect the airflow prevention 
device with the inlet plenum. Insulate the ductwork and inlet plenum 
with thermal insulation that has a nominal overall resistance (R-value) 
of at least 19 hr [middot] ft\2\ [middot] [deg]F/Btu.
    2.5.1.2 If the section 2.4.2 inlet plenum is not installed, 
construct the airflow prevention device having a cross-sectional flow 
area equal to or greater than the flow area of the air inlet of the 
indoor unit. Install the airflow prevention device immediately upstream 
of the inlet of the indoor unit. If needed, use an adaptor plate or a 
short transition duct section to connect the airflow prevention device 
with the unit's air inlet. Add static pressure taps at the center of 
each face of a rectangular airflow prevention device, or at four evenly 
distributed locations along the circumference of an oval or round 
airflow prevention device. Locate the pressure taps at a distance from 
the indoor unit inlet equal to 0.5 times the square root of the cross 
sectional area of the indoor unit inlet. This location must be between 
the damper and the inlet of the indoor unit, if a damper is used. Make a 
manifold that connects the four static pressure taps using one of the 
configurations shown in Figure 9 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3). Insulate the ductwork with thermal 
insulation that has a nominal overall resistance (R-value) of at least 
19 hr[middot]ft\2\[middot] [deg]F/Btu.

2.5.2 Test Set-Up on the Inlet Side of the Indoor Unit: for Cases Where 
                No Airflow Prevention Device is Installed

    If using the section 2.4.2 inlet plenum and a grid of dry bulb 
temperature sensors, mount the grid at a location upstream of the static 
pressure taps described in section 2.4.2 of this appendix, preferably at 
the entrance plane of the inlet plenum. If the section 2.4.2

[[Page 563]]

inlet plenum is not used (i.e. for non-ducted units) locate a grid 
approximately 6 inches upstream of the indoor unit inlet. In the case of 
a system having multiple non-ducted indoor units, do this for each 
indoor unit. Position an air sampling device, or the sensor used to 
measure the water vapor content of the inlet air, immediately upstream 
of the (each) entering air dry-bulb temperature sensor grid. If a grid 
of sensors is not used, position the entering air sampling device (or 
the sensor used to measure the water vapor content of the inlet air) as 
if the grid were present.

        2.5.3 Indoor Coil Static Pressure Difference Measurement

    Fabricate pressure taps meeting all requirements described in 
section 6.5.2 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3) and illustrated in Figure 2A of AMCA 210-2007 (incorporated 
by reference, see Sec. 430.3), however, if adhering strictly to the 
description in section 6.5.2 of ANSI/ASHRAE 37-2009, the minimum 
pressure tap length of 2.5 times the inner diameter of Figure 2A of AMCA 
210-2007 is waived. Use a differential pressure measuring instrument 
that is accurate to within 0.01 inches of water 
and has a resolution of at least 0.01 inches of water to measure the 
static pressure difference between the indoor coil air inlet and outlet. 
Connect one side of the differential pressure instrument to the 
manifolded pressure taps installed in the outlet plenum. Connect the 
other side of the instrument to the manifolded pressure taps located in 
either the inlet plenum or incorporated within the airflow prevention 
device. For non-ducted systems that are tested with multiple outlet 
plenums, measure the static pressure within each outlet plenum relative 
to the surrounding atmosphere.

         2.5.4 Test Set-Up on the Outlet Side of the Indoor Coil

    a. Install an interconnecting duct between the outlet plenum 
described in section 2.4.1 of this appendix and the airflow measuring 
apparatus described below in section 2.6 of this appendix. The cross-
sectional flow area of the interconnecting duct must be equal to or 
greater than the flow area of the outlet plenum or the common duct used 
when testing non-ducted units having multiple indoor coils. If needed, 
use adaptor plates or transition duct sections to allow the connections. 
To minimize leakage, tape joints within the interconnecting duct (and 
the outlet plenum). Construct or insulate the entire flow section with 
thermal insulation having a nominal overall resistance (R-value) of at 
least 19 hr[middot]ft\2\[middot] [deg]F/Btu.
    b. Install a grid(s) of dry-bulb temperature sensors inside the 
interconnecting duct. Also, install an air sampling device, or the 
sensor(s) used to measure the water vapor content of the outlet air, 
inside the interconnecting duct. Locate the dry-bulb temperature grid(s) 
upstream of the air sampling device (or the in-duct sensor(s) used to 
measure the water vapor content of the outlet air). Turn off the sampler 
fan motor during the cyclic tests. Air leaving an indoor unit that is 
sampled by an air sampling device for remote water-vapor-content 
measurement must be returned to the interconnecting duct at a location:
    (1) Downstream of the air sampling device;
    (2) On the same side of the outlet air damper as the air sampling 
device; and
    (3) Upstream of the section 2.6 airflow measuring apparatus.

        2.5.4.1 Outlet Air Damper Box Placement and Requirements

    If using an outlet air damper box (see section 2.5 of this 
appendix), the leakage rate from the combination of the outlet plenum, 
the closed damper, and the duct section that connects these two 
components must not exceed 20 cubic feet per minute when a negative 
pressure of 1 inch of water column is maintained at the plenum's inlet.

       2.5.4.2 Procedures to Minimize Temperature Maldistribution

    Use these procedures if necessary to correct temperature 
maldistributions. Install a mixing device(s) upstream of the outlet air, 
dry-bulb temperature grid (but downstream of the outlet plenum static 
pressure taps). Use a perforated screen located between the mixing 
device and the dry-bulb temperature grid, with a maximum open area of 40 
percent. One or both items should help to meet the maximum outlet air 
temperature distribution specified in section 3.1.8 of this appendix. 
Mixing devices are described in sections 5.3.2 and 5.3.3 of ANSI/ASHRAE 
41.1-2013 and section 5.2.2 of ASHRAE 41.2-1987 (RA 1992) (incorporated 
by reference, see Sec. 430.3).

                     2.5.4.3 Minimizing Air Leakage

    For small-duct, high-velocity systems, install an air damper near 
the end of the interconnecting duct, just prior to the transition to the 
airflow measuring apparatus of section 2.6 of this appendix. To minimize 
air leakage, adjust this damper such that the pressure in the receiving 
chamber of the airflow measuring apparatus is no more than 0.5 inch of 
water higher than the surrounding test room ambient. If applicable, in 
lieu of installing a separate damper, use the outlet air damper box of 
sections 2.5 and 2.5.4.1 of this appendix if it allows variable 
positioning. Also apply these steps to any conventional indoor blower 
unit that creates a static pressure within the receiving chamber

[[Page 564]]

of the airflow measuring apparatus that exceeds the test room ambient 
pressure by more than 0.5 inches of water column.

                 2.5.5 Dry Bulb Temperature Measurement

    a. Measure dry bulb temperatures as specified in sections 4, 5.3, 6, 
and 7 of ANSI/ASHRAE 41.1-2013 (incorporated by reference, see Sec. 
430.3).
    b. Distribute the sensors of a dry-bulb temperature grid over the 
entire flow area. The required minimum is 9 sensors per grid.

                  2.5.6 Water Vapor Content Measurement

    Determine water vapor content by measuring dry-bulb temperature 
combined with the air wet-bulb temperature, dew point temperature, or 
relative humidity. If used, construct and apply wet-bulb temperature 
sensors as specified in sections 4, 5, 6, 7.2, 7.3, and 7.4 of ASHRAE 
41.6-2014 (incorporated by reference, see Sec. 430.3). The temperature 
sensor (wick removed) must be accurate to within 0.2 [deg]F. If used, apply dew point hygrometers as 
specified in sections 4, 5, 6, 7.1, and 7.4 of ASHRAE 41.6-2014. The dew 
point hygrometers must be accurate to within 0.4 
[deg]F when operated at conditions that result in the evaluation of dew 
points above 35 [deg]F. If used, a relative humidity (RH) meter must be 
accurate to within 0.7% RH. Other means to 
determine the psychrometric state of air may be used as long as the 
measurement accuracy is equivalent to or better than the accuracy 
achieved from using a wet-bulb temperature sensor that meets the above 
specifications.

              2.5.7 Air Damper Box Performance Requirements

    If used (see section 2.5 of this appendix), the air damper box(es) 
must be capable of being completely opened or completely closed within 
10 seconds for each action.

                     2.6 Airflow Measuring Apparatus

    a. Fabricate and operate an airflow measuring apparatus as specified 
in section 6.2 and 6.3 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3). Place the static pressure taps and position 
the diffusion baffle (settling means) relative to the chamber inlet as 
indicated in Figure 12 of AMCA 210-07 and/or Figure 14 of ASHRAE 41.2-
1987 (RA 1992) (incorporated by reference, see Sec. 430.3). When 
measuring the static pressure difference across nozzles and/or velocity 
pressure at nozzle throats using electronic pressure transducers and a 
data acquisition system, if high frequency fluctuations cause 
measurement variations to exceed the test tolerance limits specified in 
section 9.2 and Table 2 of ANSI/ASHRAE 37-2009, dampen the measurement 
system such that the time constant associated with response to a step 
change in measurement (time for the response to change 63% of the way 
from the initial output to the final output) is no longer than five 
seconds.
    b. Connect the airflow measuring apparatus to the interconnecting 
duct section described in section 2.5.4 of this appendix. See sections 
6.1.1, 6.1.2, and 6.1.4, and Figures 1, 2, and 4 of ANSI/ASHRAE 37-2009; 
and Figures D1, D2, and D4 of AHRI 210/240-2008 (incorporated by 
reference, see Sec. 430.3) with Addendum 1 and 2 for illustrative 
examples of how the test apparatus may be applied within a complete 
laboratory set-up. Instead of following one of these examples, an 
alternative set-up may be used to handle the air leaving the airflow 
measuring apparatus and to supply properly conditioned air to the test 
unit's inlet. The alternative set-up, however, must not interfere with 
the prescribed means for measuring airflow rate, inlet and outlet air 
temperatures, inlet and outlet water vapor contents, and external static 
pressures, nor create abnormal conditions surrounding the test unit. 
(Note: Do not use an enclosure as described in section 6.1.3 of ANSI/
ASHRAE 37-2009 when testing triple-split units.)

                      2.7 Electrical Voltage Supply

    Perform all tests at the voltage specified in section 6.1.3.2 of 
AHRI 210/240-2008 (incorporated by reference, see Sec. 430.3) for 
``Standard Rating Tests.'' If either the indoor or the outdoor unit has 
a 208V or 200V nameplate voltage and the other unit has a 230V nameplate 
rating, select the voltage supply on the outdoor unit for testing. 
Otherwise, supply each unit with its own nameplate voltage. Measure the 
supply voltage at the terminals on the test unit using a volt meter that 
provides a reading that is accurate to within 1.0 
percent of the measured quantity.

              2.8 Electrical Power and Energy Measurements

    a. Use an integrating power (watt-hour) measuring system to 
determine the electrical energy or average electrical power supplied to 
all components of the air conditioner or heat pump (including auxiliary 
components such as controls, transformers, crankcase heater, integral 
condensate pump on non-ducted indoor units, etc.). The watt-hour 
measuring system must give readings that are accurate to within 0.5 percent. For cyclic tests, this accuracy is required 
during both the ON and OFF cycles. Use either two different scales on 
the same watt-hour meter or two separate watt-hour meters. Activate the 
scale or meter having the lower power rating within 15 seconds after 
beginning an OFF cycle. Activate the scale or meter having the higher 
power rating within 15 seconds prior to beginning an ON cycle. For 
ducted blower coil systems, the ON cycle lasts from compressor ON to 
indoor blower OFF. For ducted coil-only systems, the ON

[[Page 565]]

cycle lasts from compressor ON to compressor OFF. For non-ducted units, 
the ON cycle lasts from indoor blower ON to indoor blower OFF. When 
testing air conditioners and heat pumps having a variable-speed 
compressor, avoid using an induction watt/watt-hour meter.
    b. When performing section 3.5 and/or 3.8 cyclic tests on non-ducted 
units, provide instrumentation to determine the average electrical power 
consumption of the indoor blower motor to within 1.0 percent. If required according to sections 3.3, 3.4, 
3.7, 3.9.1 of this appendix, and/or 3.10 of this appendix, this same 
instrumentation requirement (to determine the average electrical power 
consumption of the indoor blower motor to within 1.0 percent) applies when testing air conditioners and 
heat pumps having a variable-speed constant-air-volume-rate indoor 
blower or a variable-speed, variable-air-volume-rate indoor blower.

                          2.9 Time Measurements

    Make elapsed time measurements using an instrument that yields 
readings accurate to within 0.2 percent.

   2.10 Test Apparatus for the Secondary Space Conditioning Capacity 
                               Measurement

    For all tests, use the indoor air enthalpy method to measure the 
unit's capacity. This method uses the test set-up specified in sections 
2.4 to 2.6 of this appendix. In addition, for all steady-state tests, 
conduct a second, independent measurement of capacity as described in 
section 3.1.1 of this appendix. For split systems, use one of the 
following secondary measurement methods: outdoor air enthalpy method, 
compressor calibration method, or refrigerant enthalpy method. For 
single-package units, use either the outdoor air enthalpy method or the 
compressor calibration method as the secondary measurement.

                   2.10.1 Outdoor Air Enthalpy Method

    a. To make a secondary measurement of indoor space conditioning 
capacity using the outdoor air enthalpy method, do the following:
    (1) Measure the electrical power consumption of the test unit;
    (2) Measure the air-side capacity at the outdoor coil; and
    (3) Apply a heat balance on the refrigerant cycle.
    b. The test apparatus required for the outdoor air enthalpy method 
is a subset of the apparatus used for the indoor air enthalpy method. 
Required apparatus includes the following:
    (1) On the outlet side, an outlet plenum containing static pressure 
taps (sections 2.4, 2.4.1, and 2.5.3 of this appendix),
    (2) An airflow measuring apparatus (section 2.6 of this appendix),
    (3) A duct section that connects these two components and itself 
contains the instrumentation for measuring the dry-bulb temperature and 
water vapor content of the air leaving the outdoor coil (sections 2.5.4, 
2.5.5, and 2.5.6 of this appendix), and
    (4) On the inlet side, a sampling device and temperature grid 
(section 2.11.b of this appendix).
    c. During the free outdoor air tests described in sections 3.11.1 
and 3.11.1.1 of this appendix, measure the evaporator and condenser 
temperatures or pressures. On both the outdoor coil and the indoor coil, 
solder a thermocouple onto a return bend located at or near the midpoint 
of each coil or at points not affected by vapor superheat or liquid 
subcooling. Alternatively, if the test unit is not sensitive to the 
refrigerant charge, install pressure gages to the access valves or to 
ports created from tapping into the suction and discharge lines 
according to sections 7.4.2 and 8.2.5 of ANSI/ASHRAE 37-2009. Use this 
alternative approach when testing a unit charged with a zeotropic 
refrigerant having a temperature glide in excess of 1 [deg]F at the 
specified test conditions.

                  2.10.2 Compressor Calibration Method

    Measure refrigerant pressures and temperatures to determine the 
evaporator superheat and the enthalpy of the refrigerant that enters and 
exits the indoor coil. Determine refrigerant flow rate or, when the 
superheat of the refrigerant leaving the evaporator is less than 5 
[deg]F, total capacity from separate calibration tests conducted under 
identical operating conditions. When using this method, install 
instrumentation and measure refrigerant properties according to section 
7.4.2 and 8.2.5 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3). If removing the refrigerant before applying refrigerant 
lines and subsequently recharging, use the steps in 7.4.2 of ANSI/ASHRAE 
37-2009 in addition to the methods of section 2.2.5 of this appendix to 
confirm the refrigerant charge. Use refrigerant temperature and pressure 
measuring instruments that meet the specifications given in sections 
5.1.1 and 5.2 of ANSI/ASHRAE 37-2009.

                   2.10.3 Refrigerant Enthalpy Method

    For this method, calculate space conditioning capacity by 
determining the refrigerant enthalpy change for the indoor coil and 
directly measuring the refrigerant flow rate. Use section 7.5.2 of ANSI/
ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3) for the 
requirements for this method, including the additional instrumentation 
requirements, and information on placing the flow

[[Page 566]]

meter and a sight glass. Use refrigerant temperature, pressure, and flow 
measuring instruments that meet the specifications given in sections 
5.1.1, 5.2, and 5.5.1 of ANSI/ASHRAE 37-2009. Refrigerant flow 
measurement device(s), if used, must be either elevated at least two 
feet from the test chamber floor or placed upon insulating material 
having a total thermal resistance of at least R-12 and extending at 
least one foot laterally beyond each side of the device(s)' exposed 
surfaces.

            2.11 Measurement of Test Room Ambient Conditions

    Follow instructions for setting up air sampling device and 
aspirating psychrometer as described in section 2.14 of this appendix, 
unless otherwise instructed in this section.
    a. If using a test set-up where air is ducted directly from the 
conditioning apparatus to the indoor coil inlet (see Figure 2, Loop Air-
Enthalpy Test Method Arrangement, of ANSI/ASHRAE 37-2009 (incorporated 
by reference, see Sec. 430.3)), add instrumentation to permit 
measurement of the indoor test room dry-bulb temperature.
    b. On the outdoor side, use one of the following two approaches, 
except that approach (1) is required for all evaporatively cooled units 
and units that transfer condensate to the outdoor unit for evaporation 
using condenser heat.
    (1) Use sampling tree air collection on all air-inlet surfaces of 
the outdoor unit.
    (2) Use sampling tree air collection on one or more faces of the 
outdoor unit and demonstrate air temperature uniformity as follows. 
Install a grid of evenly distributed thermocouples on each air-
permitting face on the inlet of the outdoor unit. Install the 
thermocouples on the air sampling device, locate them individually or 
attach them to a wire structure. If not installed on the air sampling 
device, install the thermocouple grid 6 to 24 inches from the unit. 
Evenly space the thermocouples across the coil inlet surface and install 
them to avoid sampling of discharge air or blockage of air 
recirculation. The grid of thermocouples must provide at least 16 
measuring points per face or one measurement per square foot of inlet 
face area, whichever is less. Construct this grid and use as per section 
5.3 of ANSI/ASHRAE 41.1-2013 (incorporated by reference, see Sec. 
430.3). The maximum difference between the average temperatures measured 
during the test period of any two pairs of these individual 
thermocouples located at any of the faces of the inlet of the outdoor 
unit, must not exceed 2.0 [deg]F, otherwise use approach (1).
    Locate the air sampling devices at the geometric center of each 
side; the branches may be oriented either parallel or perpendicular to 
the longer edges of the air inlet area. Size the air sampling devices in 
the outdoor air inlet location such that they cover at least 75% of the 
face area of the side of the coil that they are measuring.
    Review air distribution at the test facility point of supply to the 
unit and remediate as necessary prior to the beginning of testing. 
Mixing fans can be used to ensure adequate air distribution in the test 
room. If used, orient mixing fans such that they are pointed away from 
the air intake so that the mixing fan exhaust does not affect the 
outdoor coil air volume rate. Particular attention should be given to 
prevent the mixing fans from affecting (enhancing or limiting) 
recirculation of condenser fan exhaust air back through the unit. Any 
fan used to enhance test room air mixing shall not cause air velocities 
in the vicinity of the test unit to exceed 500 feet per minute.
    The air sampling device may be larger than the face area of the side 
being measured. Take care, however, to prevent discharge air from being 
sampled. If an air sampling device dimension extends beyond the inlet 
area of the unit, block holes in the air sampling device to prevent 
sampling of discharge air. Holes can be blocked to reduce the region of 
coverage of the intake holes both in the direction of the trunk axis or 
perpendicular to the trunk axis. For intake hole region reduction in the 
direction of the trunk axis, block holes of one or more adjacent pairs 
of branches (the branches of a pair connect opposite each other at the 
same trunk location) at either the outlet end or the closed end of the 
trunk. For intake hole region reduction perpendicular to the trunk axis, 
block off the same number of holes on each branch on both sides of the 
trunk.
    Connect a maximum of four (4) air sampling devices to each 
aspirating psychrometer. In order to proportionately divide the flow 
stream for multiple air sampling devices for a given aspirating 
psychrometer, the tubing or conduit conveying sampled air to the 
psychrometer must be of equivalent lengths for each air sampling device. 
Preferentially, the air sampling device should be hard connected to the 
aspirating psychrometer, but if space constraints do not allow this, the 
assembly shall have a means of allowing a flexible tube to connect the 
air sampling device to the aspirating psychrometer. Insulate and route 
the tubing or conduit to prevent heat transfer to the air stream. 
Insulate any surface of the air conveying tubing in contact with 
surrounding air at a different temperature than the sampled air with 
thermal insulation with a nominal thermal resistance (R-value) of at 
least 19 hr  ft\2\  [deg]F/Btu. 
Alternatively the conduit may have lower thermal resistance if 
additional sensor(s) are used to measure dry bulb temperature at the 
outlet of each air sampling device. No part of the air sampling device 
or the tubing conducting the sampled air to the sensors may be within 
two inches of the test chamber floor.

[[Page 567]]

    Take pairs of measurements (e.g. dry bulb temperature and wet bulb 
temperature) used to determine water vapor content of sampled air in the 
same location.

                 2.12 Measurement of Indoor Blower Speed

    When required, measure fan speed using a revolution counter, 
tachometer, or stroboscope that gives readings accurate to within 1.0 percent.

                 2.13 Measurement of Barometric Pressure

    Determine the average barometric pressure during each test. Use an 
instrument that meets the requirements specified in section 5.2 of ANSI/
ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3).

    2.14 Air Sampling Device and Aspirating Psychrometer Requirements

    Make air temperature measurements in accordance with ANSI/ASHRAE 
41.1-2013 (incorporated by reference, see Sec. 430.3), unless otherwise 
instructed in this section.

                 2.14.1 Air Sampling Device Requirements

    The air sampling device is intended to draw in a sample of the air 
at the critical locations of a unit under test. Construct the device 
from stainless steel, plastic or other suitable, durable materials. It 
shall have a main flow trunk tube with a series of branch tubes 
connected to the trunk tube. Holes must be on the side of the sampler 
facing the upstream direction of the air source. Use other sizes and 
rectangular shapes, and scale them accordingly with the following 
guidelines:
    1. Minimum hole density of 6 holes per square foot of area to be 
sampled.
    2. Sampler branch tube pitch (spacing) of 6  3 
in.
    3. Manifold trunk to branch diameter ratio having a minimum of 3:1 
ratio.
    4. Distribute hole pitch (spacing) equally over the branch (\1/2\ 
pitch from the closed end to the nearest hole).
    5. Maximum individual hole to branch diameter ratio of 1:2 (1:3 
preferred).
    The minimum average velocity through the air sampling device holes 
must be 2.5 ft/s as determined by evaluating the sum of the open area of 
the holes as compared to the flow area in the aspirating psychrometer.

                     2.14.2 Aspirating Psychrometer

    The psychrometer consists of a flow section and a fan to draw air 
through the flow section and measures an average value of the sampled 
air stream. At a minimum, the flow section shall have a means for 
measuring the dry bulb temperature (typically, a resistance temperature 
device (RTD) and a means for measuring the humidity (RTD with wetted 
sock, chilled mirror hygrometer, or relative humidity sensor). The 
aspirating psychrometer shall include a fan that either can be adjusted 
manually or automatically to maintain required velocity across the 
sensors.
    Construct the psychrometer using suitable material which may be 
plastic (such as polycarbonate), aluminum or other metallic materials. 
Construct all psychrometers for a given system being tested, using the 
same material. Design the psychrometers such that radiant heat from the 
motor (for driving the fan that draws sampled air through the 
psychrometer) does not affect sensor measurements. For aspirating 
psychrometers, velocity across the wet bulb sensor must be 1000  200 ft/min. For all other psychrometers, velocity must 
be as specified by the sensor manufacturer.

                          3 Testing Procedures

                        3.1 General Requirements

    If, during the testing process, an equipment set-up adjustment is 
made that would have altered the performance of the unit during any 
already completed test, then repeat all tests affected by the 
adjustment. For cyclic tests, instead of maintaining an air volume rate, 
for each airflow nozzle, maintain the static pressure difference or 
velocity pressure during an ON period at the same pressure difference or 
velocity pressure as measured during the steady-state test conducted at 
the same test conditions.
    Use the testing procedures in this section to collect the data used 
for calculating
    (1) Performance metrics for central air conditioners and heat pumps 
during the cooling season;
    (2) Performance metrics for heat pumps during the heating season; 
and
    (3) Power consumption metric(s) for central air conditioners and 
heat pumps during the off mode season(s).

                3.1.1 Primary and Secondary Test Methods

    For all tests, use the indoor air enthalpy method test apparatus to 
determine the unit's space conditioning capacity. The procedure and data 
collected, however, differ slightly depending upon whether the test is a 
steady-state test, a cyclic test, or a frost accumulation test. The 
following sections described these differences. For full-capacity 
cooling-mode test and (for a heat pump) the full-capacity heating-mode 
test, use one of the acceptable secondary methods specified in section 
2.10 of this appendix to determine indoor space conditioning capacity. 
Calculate this secondary check of capacity according to section 3.11 of 
this appendix. The two capacity measurements must agree to within 6 
percent to constitute a valid test. For this capacity comparison, use 
the Indoor Air Enthalpy Method capacity that is calculated in section 
7.3 of ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3)

[[Page 568]]

(and, if testing a coil-only system, compare capacities before making 
the after-test fan heat adjustments described in section 3.3, 3.4, 3.7, 
and 3.10 of this appendix). However, include the appropriate section 3.3 
to 3.5 and 3.7 to 3.10 fan heat adjustments within the indoor air 
enthalpy method capacities used for the section 4 seasonal calculations 
of this appendix.

             3.1.2 Manufacturer-Provided Equipment Overrides

    Where needed, the manufacturer must provide a means for overriding 
the controls of the test unit so that the compressor(s) operates at the 
specified speed or capacity and the indoor blower operates at the 
specified speed or delivers the specified air volume rate.

                 3.1.3 Airflow Through the Outdoor Coil

    For all tests, meet the requirements given in section 6.1.3.4 of 
AHRI 210/240-2008 (incorporated by reference, see Sec. 430.3) when 
obtaining the airflow through the outdoor coil.

                          3.1.3.1 Double-Ducted

    For products intended to be installed with the outdoor airflow 
ducted, install the unit with outdoor coil ductwork installed per 
manufacturer installation instructions. The unit must operate between 
0.10 and 0.15 in H2O external static pressure. Make external 
static pressure measurements in accordance with ANSI/ASHRAE 37-2009 
section 6.4 and 6.5.

                  3.1.4 Airflow Through the Indoor Coil

    Determine airflow setting(s) before testing begins. Unless otherwise 
specified within this or its subsections, make no changes to the airflow 
setting(s) after initiation of testing.

                3.1.4.1 Cooling Full-Load Air Volume Rate

      3.1.4.1.1 Cooling Full-Load Air Volume Rate for Ducted Units

    Identify the certified Cooling full-load air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified Cooling full-load air volume rate, use a value equal to the 
certified cooling capacity of the unit times 400 scfm per 12,000 Btu/h. 
If there are no instructions for setting fan speed or controls, use the 
as-shipped settings. Use the following procedure to confirm and, if 
necessary, adjust the Cooling full-load air volume rate and the fan 
speed or control settings to meet each test procedure requirement:
    a. For all ducted blower coil systems, except those having a 
constant-air-volume-rate indoor blower:
    Step (1) Operate the unit under conditions specified for the A (for 
single-stage units) or A2 test using the certified fan speed 
or controls settings, and adjust the exhaust fan of the airflow 
measuring apparatus to achieve the certified Cooling full-load air 
volume rate;
    Step (2) Measure the external static pressure;
    Step (3) If this external static pressure is equal to or greater 
than the applicable minimum external static pressure cited in Table 4, 
the pressure requirement is satisfied; proceed to step 7 of this 
section. If this external static pressure is not equal to or greater 
than the applicable minimum external static pressure cited in Table 4, 
proceed to step 4 of this section;
    Step (4) Increase the external static pressure by adjusting the 
exhaust fan of the airflow measuring apparatus until either
    (i) The applicable Table 4 minimum is equaled or
    (ii) The measured air volume rate equals 90 percent or less of the 
Cooling full-load air volume rate, whichever occurs first;
    Step (5) If the conditions of step 4 (i) of this section occur 
first, the pressure requirement is satisfied; proceed to step 7 of this 
section. If the conditions of step 4 (ii) of this section occur first, 
proceed to step 6 of this section;
    Step (6) Make an incremental change to the setup of the indoor 
blower (e.g., next highest fan motor pin setting, next highest fan motor 
speed) and repeat the evaluation process beginning above, at step 1 of 
this section. If the indoor blower setup cannot be further changed, 
increase the external static pressure by adjusting the exhaust fan of 
the airflow measuring apparatus until the applicable Table 4 minimum is 
equaled; proceed to step 7 of this section;
    Step (7) The airflow constraints have been satisfied. Use the 
measured air volume rate as the Cooling full-load air volume rate. Use 
the final fan speed or control settings for all tests that use the 
Cooling full-load air volume rate.
    b. For ducted blower coil systems with a constant-air-volume-rate 
indoor blower. For all tests that specify the Cooling full-load air 
volume rate, obtain an external static pressure as close to (but not 
less than) the applicable Table 4 value that does not cause automatic 
shutdown of the indoor blower or air volume rate variation 
QVar, defined as follows, greater than 10 percent.

[[Page 569]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.153


Where:

Qmax = maximum measured airflow value

Qmin = minimum measured airflow value

QVar = airflow variance, percent

    Additional test steps as described in section 3.3.e of this appendix 
are required if the measured external static pressure exceeds the target 
value by more than 0.03 inches of water.
    c. For coil-only indoor units. For the A or A2 Test, 
(exclusively), the pressure drop across the indoor coil assembly must 
not exceed 0.30 inches of water. If this pressure drop is exceeded, 
reduce the air volume rate until the measured pressure drop equals the 
specified maximum. Use this reduced air volume rate for all tests that 
require the Cooling full-load air volume rate.

\1\ For ducted units tested without an air filter installed, increase
  the applicable tabular value by 0.08 inches of water.
\2\ See section 1.2, Definitions, to determine for which Table 4 product
  variety and associated minimum external static pressure requirement
  equipment qualifies.
\3\ If a closed-loop, air-enthalpy test apparatus is used on the indoor
  side, limit the resistance to airflow on the inlet side of the indoor
  blower coil to a maximum value of 0.1 inch of water.

    d. For ducted systems having multiple indoor blowers within a single 
indoor section, obtain the full-load air volume rate with all indoor 
blowers operating unless prevented by the controls of the unit. In such 
cases, turn on the maximum number of indoor blowers permitted by the 
unit's controls. Where more than one option exists for meeting this 
``on'' indoor blower requirement, which indoor blower(s) are turned on 
must match that specified in the certification report. Conduct section 
3.1.4.1.1 setup steps for each indoor blower separately. If two or more 
indoor blowers are connected to a common duct as per section 2.4.1 of 
this appendix, temporarily divert their air volume to the test room when 
confirming or adjusting the setup configuration of individual indoor 
blowers. The allocation of the system's full-load air volume rate 
assigned to each ``on'' indoor blower must match that specified by the 
manufacturer in the certification report.

    3.1.4.1.2 Cooling Full-Load Air Volume Rate for Non-Ducted Units

    For non-ducted units, the Cooling full-load air volume rate is the 
air volume rate that results during each test when the unit is operated 
at an external static pressure of zero inches of water.

                 3.1.4.2 Cooling Minimum Air Volume Rate

    Identify the certified cooling minimum air volume rate and certified 
instructions for setting fan speed or controls. If there is no certified 
cooling minimum air volume rate, use the final indoor blower control 
settings as determined when setting the cooling full-load air volume 
rate, and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling full load air volume obtained in 
section 3.1.4.1 of this appendix. Otherwise, calculate the target 
external static pressure and follow instructions a, b, c, d, or e of 
this section. The target external static pressure, 
[Delta]Pst_i, for any test ``i'' with a specified air volume 
rate not equal to the Cooling full-load air volume rate is determined as 
follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.154

Where:

[Delta]Pst_i = target minimum external static pressure for 
          test i;


[[Page 570]]


[Delta]Pst_full = minimum external static pressure for test A 
          or A2 (Table 4);

Qi = air volume rate for test i; and

Qfull = Cooling full-load air volume rate as measured after 
          setting and/or adjustment as described in section 3.1.4.1.1 of 
          this appendix.

    a. For a ducted blower coil system without a constant-air-volume 
indoor blower, adjust for external static pressure as follows:
    Step (1) Operate the unit under conditions specified for the 
B1 test using the certified fan speed or controls settings, 
and adjust the exhaust fan of the airflow measuring apparatus to achieve 
the certified cooling minimum air volume rate;
    Step (2) Measure the external static pressure;
    Step (3) If this pressure is equal to or greater than the minimum 
external static pressure computed above, the pressure requirement is 
satisfied; proceed to step 7 of this section. If this pressure is not 
equal to or greater than the minimum external static pressure computed 
above, proceed to step 4 of this section;
    Step (4) Increase the external static pressure by adjusting the 
exhaust fan of the airflow measuring apparatus until either
    (i) The pressure is equal to the minimum external static pressure 
computed above or
    (ii) The measured air volume rate equals 90 percent or less of the 
cooling minimum air volume rate, whichever occurs first;
    Step (5) If the conditions of step 4 (i) of this section occur 
first, the pressure requirement is satisfied; proceed to step 7 of this 
section. If the conditions of step 4 (ii) of this section occur first, 
proceed to step 6 of this section;
    Step (6) Make an incremental change to the setup of the indoor 
blower (e.g., next highest fan motor pin setting, next highest fan motor 
speed) and repeat the evaluation process beginning above, at step 1 of 
this section. If the indoor blower setup cannot be further changed, 
increase the external static pressure by adjusting the exhaust fan of 
the airflow measuring apparatus until it equals the minimum external 
static pressure computed above; proceed to step 7 of this section;
    Step (7) The airflow constraints have been satisfied. Use the 
measured air volume rate as the cooling minimum air volume rate. Use the 
final fan speed or control settings for all tests that use the cooling 
minimum air volume rate.
    b. For ducted units with constant-air-volume indoor blowers, conduct 
all tests that specify the cooling minimum air volume rate--(i.e., the 
A1, B1, C1, F1, and 
G1 Tests)--at an external static pressure that does not cause 
an automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than the 
target minimum external static pressure. Additional test steps as 
described in section 3.3.e of this appendix are required if the measured 
external static pressure exceeds the target value by more than 0.03 
inches of water.
    c. For ducted two-capacity coil-only systems, the cooling minimum 
air volume rate is the higher of--
    (1) The rate specified by the installation instructions included 
with the unit by the manufacturer; or
    (2) 75 percent of the cooling full-load air volume rate. During the 
laboratory tests on a coil-only (fanless) system, obtain this cooling 
minimum air volume rate regardless of the pressure drop across the 
indoor coil assembly.
    d. For non-ducted units, the cooling minimum air volume rate is the 
air volume rate that results during each test when the unit operates at 
an external static pressure of zero inches of water and at the indoor 
blower setting used at low compressor capacity (two-capacity system) or 
minimum compressor speed (variable-speed system). For units having a 
single-speed compressor and a variable-speed variable-air-volume-rate 
indoor blower, use the lowest fan setting allowed for cooling.
    e. For ducted systems having multiple indoor blowers within a single 
indoor section, operate the indoor blowers such that the lowest air 
volume rate allowed by the unit's controls is obtained when operating 
the lone single-speed compressor or when operating at low compressor 
capacity while meeting the requirements of section 2.2.3.2 of this 
appendix for the minimum number of blowers that must be turned off. 
Using the target external static pressure and the certified air volume 
rates, follow the procedures described in section 3.1.4.2.a of this 
appendix if the indoor blowers are not constant-air-volume indoor 
blowers or as described in section 3.1.4.2.b of this appendix if the 
indoor blowers are not constant-air-volume indoor blowers. The sum of 
the individual ``on'' indoor blowers' air volume rates is the cooling 
minimum air volume rate for the system.

              3.1.4.3 Cooling Intermediate Air Volume Rate

    Identify the certified cooling intermediate air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified cooling intermediate air volume rate, use the final indoor 
blower control settings as determined when setting the cooling full load 
air volume rate, and readjust the exhaust fan of the airflow measuring 
apparatus if necessary to reset to the cooling full load air volume 
obtained in section 3.1.4.1 of this appendix. Otherwise, calculate 
target minimum external static pressure as described in section 3.1.4.2 
of this appendix, and set the air volume rate as follows.

[[Page 571]]

    a. For a ducted blower coil system without a constant-air-volume 
indoor blower, adjust for external static pressure as described in 
section 3.1.4.2.a of this appendix for cooling minimum air volume rate.
    b. For a ducted blower coil system with a constant-air-volume indoor 
blower, conduct the EV Test at an external static pressure 
that does not cause an automatic shutdown of the indoor blower or air 
volume rate variation QVar, defined in section 3.1.4.1.1.b of 
this appendix, greater than 10 percent, while being as close to, but not 
less than the target minimum external static pressure. Additional test 
steps as described in section 3.3.e of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For non-ducted units, the cooling intermediate air volume rate is 
the air volume rate that results when the unit operates at an external 
static pressure of zero inches of water and at the fan speed selected by 
the controls of the unit for the EV Test conditions.

                3.1.4.4 Heating Full-Load Air Volume Rate

3.1.4.4.1 Ducted Heat Pumps Where the Heating and Cooling Full-Load Air 
                        Volume Rates Are the Same

    a. Use the Cooling full-load air volume rate as the heating full-
load air volume rate for:
    (1) Ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, and that operate at the same airflow-
control setting during both the A (or A2) and the H1 (or 
H12) Tests;
    (2) Ducted blower coil system heat pumps with constant-air-flow 
indoor blowers that provide the same airflow for the A (or 
A2) and the H1 (or H12) Tests; and
    (3) Ducted heat pumps that are tested with a coil-only indoor unit 
(except two-capacity northern heat pumps that are tested only at low 
capacity cooling--see section 3.1.4.4.2 of this appendix).
    b. For heat pumps that meet the above criteria ``1'' and ``3,'' no 
minimum requirements apply to the measured external or internal, 
respectively, static pressure. Use the final indoor blower control 
settings as determined when setting the Cooling full-load air volume 
rate, and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling full-load air volume obtained in 
section 3.1.4.1 of this appendix. For heat pumps that meet the above 
criterion ``2,'' test at an external static pressure that does not cause 
an automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than, the 
same Table 4 minimum external static pressure as was specified for the A 
(or A2) cooling mode test. Additional test steps as described 
in section 3.9.1.c of this appendix are required if the measured 
external static pressure exceeds the target value by more than 0.03 
inches of water.

3.1.4.4.2 Ducted Heat Pumps Where the Heating and Cooling Full-Load Air 
 Volume Rates Are Different Due to Changes in Indoor Blower Operation, 
              i.e. Speed Adjustment by the System Controls

    Identify the certified heating full-load air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified heating full-load air volume rate, use the final indoor blower 
control settings as determined when setting the cooling full-load air 
volume rate, and readjust the exhaust fan of the airflow measuring 
apparatus if necessary to reset to the cooling full-load air volume 
obtained in section 3.1.4.1 of this appendix. Otherwise, calculate the 
target minimum external static pressure as described in section 3.1.4.2 
of this appendix and set the air volume rate as follows.
    a. For ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, adjust for external static pressure 
as described in section 3.1.4.2.a of this appendix for cooling minimum 
air volume rate.
    b. For ducted heat pumps tested with constant-air-volume indoor 
blowers installed, conduct all tests that specify the heating full-load 
air volume rate at an external static pressure that does not cause an 
automatic shutdown of the indoor blower or air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than the 
target minimum external static pressure. Additional test steps as 
described in section 3.9.1.c of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. When testing ducted, two-capacity blower coil system northern 
heat pumps (see section 1.2 of this appendix, Definitions), use the 
appropriate approach of the above two cases. For coil-only system 
northern heat pumps, the heating full-load air volume rate is the lesser 
of the rate specified by the manufacturer in the installation 
instructions included with the unit or 133 percent of the cooling full-
load air volume rate. For this latter case, obtain the heating full-load 
air volume rate regardless of the pressure drop across the indoor coil 
assembly.
    d. For ducted systems having multiple indoor blowers within a single 
indoor section, obtain the heating full-load air volume rate using the 
same ``on'' indoor blowers as used for the Cooling full-load air volume 
rate. Using the target external static pressure and the certified air 
volume rates, follow the procedures as described in section 3.1.4.4.2.a 
of this appendix if the indoor blowers are not

[[Page 572]]

constant-air-volume indoor blowers or as described in section 
3.1.4.4.2.b of this appendix if the indoor blowers are constant-air-
volume indoor blowers. The sum of the individual ``on'' indoor blowers' 
air volume rates is the heating full-load air volume rate for the 
system.

                3.1.4.4.3 Ducted Heating-Only Heat Pumps

    Identify the certified heating full-load air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified heating full-load air volume rate, use a value equal to the 
certified heating capacity of the unit times 400 scfm per 12,000 Btu/h. 
If there are no instructions for setting fan speed or controls, use the 
as-shipped settings.
    a. For all ducted heating-only blower coil system heat pumps, except 
those having a constant-air-volume-rate indoor blower. Conduct the 
following steps only during the first test, the H1 or H12 
test:
    Step (1) Adjust the exhaust fan of the airflow measuring apparatus 
to achieve the certified heating full-load air volume rate.
    Step (2) Measure the external static pressure.
    Step (3) If this pressure is equal to or greater than the Table 4 
minimum external static pressure that applies given the heating-only 
heat pump's rated heating capacity, the pressure requirement is 
satisfied; proceed to step 7 of this section. If this pressure is not 
equal to or greater than the applicable Table 4 minimum external static 
pressure, proceed to step 4 of this section;
    Step (4) Increase the external static pressure by adjusting the 
exhaust fan of the airflow measuring apparatus until either--
    (i) The pressure is equal to the applicable Table 4 minimum external 
static pressure; or
    (ii) The measured air volume rate equals 90 percent or less of the 
heating full-load air volume rate, whichever occurs first;
    Step (5) If the conditions of step 4 (i) of this section occur 
first, the pressure requirement is satisfied; proceed to step 7 of this 
section. If the conditions of step 4 (ii) of this section occur first, 
proceed to step 6 of this section;
    Step (6) Make an incremental change to the setup of the indoor 
blower (e.g., next highest fan motor pin setting, next highest fan motor 
speed) and repeat the evaluation process beginning above, at step 1 of 
this section. If the indoor blower setup cannot be further changed, 
increase the external static pressure by adjusting the exhaust fan of 
the airflow measuring apparatus until it equals the applicable Table 4 
minimum external static pressure; proceed to step 7 of this section;
    Step (7) The airflow constraints have been satisfied. Use the 
measured air volume rate as the heating full-load air volume rate. Use 
the final fan speed or control settings for all tests that use the 
heating full-load air volume rate.
    b. For ducted heating-only blower coil system heat pumps having a 
constant-air-volume-rate indoor blower. For all tests that specify the 
heating full-load air volume rate, obtain an external static pressure 
that does not cause an automatic shutdown of the indoor blower or air 
volume rate variation QVar, defined in section 3.1.4.1.1.b of 
this section, greater than 10 percent, while being as close to, but not 
less than, the applicable Table 4 minimum. Additional test steps as 
described in section 3.9.1.c of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For ducted heating-only coil-only system heat pumps in the H1 or 
H12 Test, (exclusively), the pressure drop across the indoor 
coil assembly must not exceed 0.30 inches of water. If this pressure 
drop is exceeded, reduce the air volume rate until the measured pressure 
drop equals the specified maximum. Use this reduced air volume rate for 
all tests that require the heating full-load air volume rate.

3.1.4.4.4 Non-Ducted Heat Pumps, Including Non-Ducted Heating-Only Heat 
                                  Pumps

    For non-ducted heat pumps, the heating full-load air volume rate is 
the air volume rate that results during each test when the unit operates 
at an external static pressure of zero inches of water.

                 3.1.4.5 Heating Minimum Air Volume Rate

 3.1.4.5.1 Ducted Heat Pumps Where the Heating and Cooling Minimum Air 
                        Volume Rates are the Same

    a. Use the cooling minimum air volume rate as the heating minimum 
air volume rate for:
    (1) Ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, and that operates at the same 
airflow-control setting during both the A1 and the 
H11 tests;
    (2) Ducted blower coil system heat pumps with constant-air-flow 
indoor blowers installed that provide the same airflow for the 
A1 and the H11 Tests; and
    (3) Ducted coil-only system heat pumps.
    b. For heat pumps that meet the above criteria ``1'' and ``3,'' no 
minimum requirements apply to the measured external or internal, 
respectively, static pressure. Use the final indoor blower control 
settings as determined when setting the cooling minimum air volume rate, 
and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling minimum air volume

[[Page 573]]

rate obtained in section 3.1.4.2 of this appendix. For heat pumps that 
meet the above criterion ``2,'' test at an external static pressure that 
does not cause an automatic shutdown of the indoor blower or air volume 
rate variation QVar, defined in section 3.1.4.1.1.b, greater 
than 10 percent, while being as close to, but not less than, the same 
target minimum external static pressure as was specified for the 
A1 cooling mode test. Additional test steps as described in 
section 3.9.1.c of this appendix are required if the measured external 
static pressure exceeds the target value by more than 0.03 inches of 
water.

 3.1.4.5.2 Ducted Heat Pumps Where the Heating and Cooling Minimum Air 
 Volume Rates Are Different Due to Indoor Blower Operation, i.e. Speed 
                    Adjustment by the System Controls

    Identify the certified heating minimum air volume rate and certified 
instructions for setting fan speed or controls. If there is no certified 
heating minimum air volume rate, use the final indoor blower control 
settings as determined when setting the cooling minimum air volume rate, 
and readjust the exhaust fan of the airflow measuring apparatus if 
necessary to reset to the cooling minimum air volume obtained in section 
3.1.4.2 of this appendix. Otherwise, calculate the target minimum 
external static pressure as described in section 3.1.4.2 of this 
appendix.
    a. For ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, adjust for external static pressure 
as described in section 3.1.4.2.a of this appendix for cooling minimum 
air volume rate.
    b. For ducted heat pumps tested with constant-air-volume indoor 
blowers installed, conduct all tests that specify the heating minimum 
air volume rate--(i.e., the H01, H11, 
H21, and H31 Tests)--at an external static 
pressure that does not cause an automatic shutdown of the indoor blower 
while being as close to, but not less than the air volume rate variation 
QVar, defined in section 3.1.4.1.1.b of this appendix, 
greater than 10 percent, while being as close to, but not less than the 
target minimum external static pressure. Additional test steps as 
described in section 3.9.1.c of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For ducted two-capacity blower coil system northern heat pumps, 
use the appropriate approach of the above two cases.
    d. For ducted two-capacity coil-only system heat pumps, use the 
cooling minimum air volume rate as the heating minimum air volume rate. 
For ducted two-capacity coil-only system northern heat pumps, use the 
cooling full-load air volume rate as the heating minimum air volume 
rate. For ducted two-capacity heating-only coil-only system heat pumps, 
the heating minimum air volume rate is the higher of the rate specified 
by the manufacturer in the test setup instructions included with the 
unit or 75 percent of the heating full-load air volume rate. During the 
laboratory tests on a coil-only system, obtain the heating minimum air 
volume rate without regard to the pressure drop across the indoor coil 
assembly.
    e. For non-ducted heat pumps, the heating minimum air volume rate is 
the air volume rate that results during each test when the unit operates 
at an external static pressure of zero inches of water and at the indoor 
blower setting used at low compressor capacity (two-capacity system) or 
minimum compressor speed (variable-speed system). For units having a 
single-speed compressor and a variable-speed, variable-air-volume-rate 
indoor blower, use the lowest fan setting allowed for heating.
    f. For ducted systems with multiple indoor blowers within a single 
indoor section, obtain the heating minimum air volume rate using the 
same ``on'' indoor blowers as used for the cooling minimum air volume 
rate. Using the target external static pressure and the certified air 
volume rates, follow the procedures as described in section 3.1.4.5.2.a 
of this appendix if the indoor blowers are not constant-air-volume 
indoor blowers or as described in section 3.1.4.5.2.b of this appendix 
if the indoor blowers are constant-air-volume indoor blowers. The sum of 
the individual ``on'' indoor blowers' air volume rates is the heating 
full-load air volume rate for the system.

              3.1.4.6 Heating Intermediate Air Volume Rate

    Identify the certified heating intermediate air volume rate and 
certified instructions for setting fan speed or controls. If there is no 
certified heating intermediate air volume rate, use the final indoor 
blower control settings as determined when setting the heating full-load 
air volume rate, and readjust the exhaust fan of the airflow measuring 
apparatus if necessary to reset to the cooling full-load air volume 
obtained in section 3.1.4.2 of this appendix. Calculate the target 
minimum external static pressure as described in section 3.1.4.2 of this 
appendix.
    a. For ducted blower coil system heat pumps that do not have a 
constant-air-volume indoor blower, adjust for external static pressure 
as described in section 3.1.4.2.a of this appendix for cooling minimum 
air volume rate.
    b. For ducted heat pumps tested with constant-air-volume indoor 
blowers installed, conduct the H2V Test at an external static 
pressure that does not cause an automatic shutdown of the indoor blower 
or air volume rate variation QVar, defined in section 
3.1.4.1.1.b of this appendix, greater than 10 percent, while being as 
close to, but not less

[[Page 574]]

than the target minimum external static pressure. Additional test steps 
as described in section 3.9.1.c of this appendix are required if the 
measured external static pressure exceeds the target value by more than 
0.03 inches of water.
    c. For non-ducted heat pumps, the heating intermediate air volume 
rate is the air volume rate that results when the heat pump operates at 
an external static pressure of zero inches of water and at the fan speed 
selected by the controls of the unit for the H2V Test 
conditions.

                 3.1.4.7 Heating Nominal Air Volume Rate

    The manufacturer must specify the heating nominal air volume rate 
and the instructions for setting fan speed or controls. Calculate target 
minimum external static pressure as described in section 3.1.4.2 of this 
appendix. Make adjustments as described in section 3.14.6 of this 
appendix for heating intermediate air volume rate so that the target 
minimum external static pressure is met or exceeded.

 3.1.5 Indoor Test Room Requirement When the Air Surrounding the Indoor 
Unit is Not Supplied From the Same Source as the Air Entering the Indoor 
                                  Unit

    If using a test set-up where air is ducted directly from the air 
reconditioning apparatus to the indoor coil inlet (see Figure 2, Loop 
Air-Enthalpy Test Method Arrangement, of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3)), maintain the dry bulb 
temperature within the test room within 5.0 [deg]F 
of the applicable sections 3.2 and 3.6 dry bulb temperature test 
condition for the air entering the indoor unit. Dew point must be within 
2 [deg]F of the required inlet conditions.

                   3.1.6 Air Volume Rate Calculations

    For all steady-state tests and for frost accumulation (H2, 
H21, H22, H2V) tests, calculate the air 
volume rate through the indoor coil as specified in sections 7.7.2.1 and 
7.7.2.2 of ANSI/ASHRAE 37-2009. When using the outdoor air enthalpy 
method, follow sections 7.7.2.1 and 7.7.2.2 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3) to calculate the air volume 
rate through the outdoor coil. To express air volume rates in terms of 
standard air, use:
[GRAPHIC] [TIFF OMITTED] TR05JA17.155

Where:

Vis = air volume rate of standard (dry) air, (ft\3\/
          min)da

Vimx = air volume rate of the air-water vapor mixture, 
          (ft\3\/min)mx

vn[min] = specific volume of air-water vapor mixture at the 
          nozzle, ft\3\ per lbm of the air-water vapor mixture

Wn = humidity ratio at the nozzle, lbm of water vapor per lbm 
          of dry air

0.075 = the density associated with standard (dry) air, (lbm/ft\3\)

vn = specific volume of the dry air portion of the mixture 
          evaluated at the dry-bulb temperature, vapor content, and 
          barometric pressure existing at the nozzle, ft\3\ per lbm of 
          dry air.

    Note: In the first printing of ANSI/ASHRAE 37-2009, the second IP 
equation for Qmi should read,
[GRAPHIC] [TIFF OMITTED] TR05JA17.156

                           3.1.7 Test Sequence

    Before making test measurements used to calculate performance, 
operate the equipment for the ``break-in'' period specified in the 
certification report, which may not exceed 20 hours. Each compressor of 
the unit must undergo this ``break-in'' period. When testing a ducted 
unit (except if a heating-only heat pump), conduct the A or 
A2 Test first to establish the cooling full-load air volume 
rate. For ducted heat pumps where the heating and cooling full-load air 
volume rates are different, make the first heating mode test one that 
requires the heating full-load air volume rate. For ducted heating-only 
heat pumps, conduct the H1 or H12 Test first to establish the 
heating full-load air volume rate. When conducting a cyclic test,

[[Page 575]]

always conduct it immediately after the steady-state test that requires 
the same test conditions. For variable-speed systems, the first test 
using the cooling minimum air volume rate should precede the 
EV Test, and the first test using the heating minimum air 
volume rate must precede the H2V Test. The test laboratory 
makes all other decisions on the test sequence.

   3.1.8 Requirement for the Air Temperature Distribution Leaving the 
                               Indoor Coil

    For at least the first cooling mode test and the first heating mode 
test, monitor the temperature distribution of the air leaving the indoor 
coil using the grid of individual sensors described in sections 2.5 and 
2.5.4 of this appendix. For the 30-minute data collection interval used 
to determine capacity, the maximum spread among the outlet dry bulb 
temperatures from any data sampling must not exceed 1.5 [deg]F. Install 
the mixing devices described in section 2.5.4.2 of this appendix to 
minimize the temperature spread.

  3.1.9 Requirement for the Air Temperature Distribution Entering the 
                              Outdoor Coil

    Monitor the Temperatures of the Air Entering the Outdoor Coil Using 
Air Sampling Devices and/or Temperature Sensor Grids, Maintaining the 
Required Tolerances, if Applicable, as Described in section 2.11 of this 
appendix

         3.1.10 Control of Auxiliary Resistive Heating Elements

    Except as noted, disable heat pump resistance elements used for 
heating indoor air at all times, including during defrost cycles and if 
they are normally regulated by a heat comfort controller. For heat pumps 
equipped with a heat comfort controller, enable the heat pump resistance 
elements only during the below-described, short test. For single-speed 
heat pumps covered under section 3.6.1 of this appendix, the short test 
follows the H1 or, if conducted, the H1C Test. For two-capacity heat 
pumps and heat pumps covered under section 3.6.2 of this appendix, the 
short test follows the H12 Test. Set the heat comfort 
controller to provide the maximum supply air temperature. With the heat 
pump operating and while maintaining the heating full-load air volume 
rate, measure the temperature of the air leaving the indoor-side 
beginning 5 minutes after activating the heat comfort controller. Sample 
the outlet dry-bulb temperature at regular intervals that span 5 minutes 
or less. Collect data for 10 minutes, obtaining at least 3 samples. 
Calculate the average outlet temperature over the 10-minute interval, 
TCC.

3.2 Cooling Mode Tests for Different Types of Air Conditioners and Heat 
                                  Pumps

  3.2.1 Tests for a System Having a Single-Speed Compressor and Fixed 
                         Cooling Air Volume Rate

    This set of tests is for single-speed-compressor units that do not 
have a cooling minimum air volume rate or a cooling intermediate air 
volume rate that is different than the cooling full load air volume 
rate. Conduct two steady-state wet coil tests, the A and B Tests. Use 
the two optional dry-coil tests, the steady-state C Test and the cyclic 
D Test, to determine the cooling mode cyclic degradation coefficient, 
CD\c\. If the two optional tests are conducted but yield a 
tested CD\c\ that exceeds the default CD\c\ or if 
the two optional tests are not conducted, assign CD\c\ the 
default value of 0.25 (for outdoor units with no match) or 0.2 (for all 
other systems). Table 5 specifies test conditions for these four tests.

\1\ The specified test condition only applies if the unit rejects condensate to the outdoor coil.
\2\ Defined in section 3.1.4.1 of this appendix.
\3\ The entering air must have a low enough moisture content so no condensate forms on the indoor coil. (It is recommended that an indoor wet-bulb
  temperature of 57 [deg]F or less be used.)
\4\ Maintain the airflow nozzles static pressure difference or velocity pressure during the ON period at the same pressure difference or velocity
  pressure as measured during the C Test.

3.2.2 Tests for a Unit Having a Single-Speed Compressor Where the Indoor 
  Section Uses a Single Variable-Speed Variable-Air-Volume Rate Indoor 
                    Blower or Multiple Indoor Blowers

   3.2.2.1 Indoor Blower Capacity Modulation That Correlates With the 
 Outdoor Dry Bulb Temperature or Systems With a Single Indoor Coil but 
                         Multiple Indoor Blowers

    Conduct four steady-state wet coil tests: The A2, 
A1, B2, and B1 tests. Use the two 
optional dry-coil tests, the steady-state C1 test and the 
cyclic D1 test, to determine the cooling mode cyclic 
degradation coefficient, CD\c\. If the two optional tests are 
conducted but yield a tested CD\c\ that exceeds the default 
CD\c\ or if the two optional tests are not conducted, assign 
CD\c\ the default value of 0.2.

    3.2.2.2 Indoor Blower Capacity Modulation Based on Adjusting the 
              Sensible to Total(S/T) Cooling Capacity Ratio

    The testing requirements are the same as specified in section 3.2.1 
of this appendix and Table 5. Use a cooling full-load air volume rate 
that represents a normal installation. If performed, conduct the steady-
state C Test and the cyclic D Test with the unit operating in the same 
S/T capacity control mode as used for the B Test.

 3.2.3 Tests for a Unit Having a Two-Capacity Compressor. (See Section 
                   1.2 of This Appendix, Definitions)

    a. Conduct four steady-state wet coil tests: the A2, 
B2, B1, and F1 Tests. Use the two 
optional dry-coil tests, the steady-state C1 Test and the 
cyclic D1 Test, to determine the cooling-mode cyclic-
degradation coefficient, CD\c\. If the two optional tests are 
conducted but yield a tested CD\c\ that exceeds the default 
CD\c\ or if the two optional tests are not conducted, assign 
CD\c\ the default value of 0.2. Table 7 specifies test 
conditions for these six tests.
    b. For units having a variable-speed indoor blower that is modulated 
to adjust the sensible to total (S/T) cooling capacity ratio, use 
cooling full-load and cooling minimum air volume rates that represent a 
normal installation. Additionally, if conducting the dry-coil tests, 
operate the unit in the same S/T capacity control mode as used for the 
B1 Test.
    c. Test two-capacity, northern heat pumps (see section 1.2 of this 
appendix, Definitions) in the same way as a single speed heat pump with 
the unit operating exclusively at low compressor capacity (see section 
3.2.1 of this appendix and Table 5).
    d. If a two-capacity air conditioner or heat pump locks out low-
capacity operation at higher outdoor temperatures, then use the two dry-
coil tests, the steady-state C2 Test and the cyclic 
D2 Test, to determine the cooling-mode cyclic-degradation 
coefficient that only applies to on/off cycling from high capacity, 
CD\c\(k=2). If the two optional tests are conducted but yield 
a tested CD\c\(k = 2) that exceeds the default 
CD\c\(k = 2) or if the two optional tests are not conducted, 
assign CD\c\(k = 2) the default value. The default 
CD\c\(k=2) is the same value as determined or

[[Page 577]]

assigned for the low-capacity cyclic-degradation coefficient, 
CD\c\ [or equivalently, CD\c\(k=1)].

        3.2.4 Tests for a Unit Having a Variable-Speed Compressor

    a. Conduct five steady-state wet coil tests: The A2, 
EV, B2, B1, and F1 Tests. 
Use the two optional dry-coil tests, the steady-state G1 Test 
and the cyclic I1 Test, to determine the cooling mode cyclic 
degradation coefficient, CD\c\. If the two optional tests are 
conducted but yield a tested CD\c\ that exceeds the default 
CD\c\ or if the two optional tests are not conducted, assign 
CD\c\ the default value of 0.25. Table 8 specifies test 
conditions for these seven tests. The compressor shall operate at the 
same cooling full speed, measured by RPM or power input frequency (Hz), 
for both the A2 and B2 tests. The compressor shall 
operate at the same cooling minimum speed, measured by RPM or power 
input frequency (Hz), for the B1, F1, 
G1, and I1 tests. Determine the cooling 
intermediate compressor speed cited in Table 8 using:
[GRAPHIC] [TIFF OMITTED] TR05JA17.157

where a tolerance of plus 5 percent or the next higher inverter 
frequency step from that calculated is allowed.
    b. For units that modulate the indoor blower speed to adjust the 
sensible to total (S/T) cooling capacity ratio, use cooling full-load, 
cooling intermediate, and cooling minimum air volume rates that 
represent a normal installation. Additionally, if conducting the dry-
coil tests, operate the unit in the same S/T capacity control mode as 
used for the F1 Test.
    c. For multiple-split air conditioners and heat pumps (except where 
noted), the following procedures supersede the above requirements: For 
all Table 8 tests specified for a minimum compressor speed, turn off at 
least one indoor unit. The manufacturer shall designate the particular 
indoor unit(s) that is turned off. The manufacturer must also specify 
the compressor speed used for the Table 8 EV Test, a cooling-
mode intermediate compressor speed that falls within \1/4\ and \3/4\ of 
the difference between the full and minimum cooling-mode speeds. The 
manufacturer should prescribe an intermediate speed that is expected to 
yield the highest EER for the given EV Test conditions

[[Page 578]]

and bracketed compressor speed range. The manufacturer can designate 
that one or more indoor units are turned off for the EV Test.

 3.2.5 Cooling Mode Tests for Northern Heat Pumps With Triple-Capacity 
                               Compressors

    Test triple-capacity, northern heat pumps for the cooling mode in 
the same way as specified in section 3.2.3 of this appendix for units 
having a two-capacity compressor.

 3.2.6 Tests for an Air Conditioner or Heat Pump Having a Single Indoor 
     Unit Having Multiple Indoor Blowers and Offering Two Stages of 
                          Compressor Modulation

    Conduct the cooling mode tests specified in section 3.2.3 of this 
appendix.

3.3 Test Procedures for Steady-State Wet Coil Cooling Mode Tests (the A, 
     A2, A1, B, B2, B1, 
                 EV, and F1 Tests)

    a. For the pretest interval, operate the test room reconditioning 
apparatus and the unit to be tested until maintaining equilibrium 
conditions for at least 30 minutes at the specified section 3.2 test 
conditions. Use the exhaust fan of the airflow measuring apparatus and, 
if installed, the indoor blower of the test unit to obtain and then 
maintain the indoor air volume rate and/or external static pressure 
specified for the particular test. Continuously record (see section 1.2 
of this appendix, Definitions):
    (1) The dry-bulb temperature of the air entering the indoor coil,
    (2) The water vapor content of the air entering the indoor coil,
    (3) The dry-bulb temperature of the air entering the outdoor coil, 
and
    (4) For the section 2.2.4 of this appendix cases where its control 
is required, the water vapor content of the air entering the outdoor 
coil.
    Refer to section 3.11 of this appendix for additional requirements 
that depend on the selected secondary test method.
    b. After satisfying the pretest equilibrium requirements, make the 
measurements specified in Table 3 of ANSI/ASHRAE 37-2009 for the indoor 
air enthalpy method and the user-selected secondary method. Make said 
Table 3 measurements at equal intervals that span 5 minutes or less. 
Continue data sampling until reaching a 30-minute period (e.g., seven 
consecutive 5-minute samples) where the test tolerances specified in 
Table 9 are satisfied. For those continuously recorded parameters, use 
the entire data set from the 30-minute interval to evaluate Table 9 
compliance. Determine the average electrical power consumption of the 
air conditioner or heat pump over the same 30-minute interval.

[[Page 579]]

    c. Calculate indoor-side total cooling capacity and sensible cooling 
capacity as specified in sections 7.3.3.1 and 7.3.3.3 of ANSI/ASHRAE 37-
2009 (incorporated by reference, see Sec. 430.3). To calculate 
capacity, use the averages of the measurements (e.g. inlet and outlet 
dry bulb and wet bulb temperatures measured at the psychrometers) that 
are continuously recorded for the same 30-minute interval used as 
described above to evaluate compliance with test tolerances. Do not 
adjust the parameters used in calculating capacity for the permitted 
variations in test conditions. Evaluate air enthalpies based on the 
measured barometric pressure. Use the values of the specific heat of air 
given in section 7.3.3.1 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3) for calculation of the sensible cooling 
capacities. Assign the average total space cooling capacity, average 
sensible cooling capacity, and electrical power consumption over the 30-
minute data collection interval to the variables Qc\k\(T), 
Qsc\k\(T) and Ec\k\(T), respectively. For these 
three variables, replace the ``T'' with the nominal outdoor temperature 
at which the test was conducted. The superscript k is used only when 
testing multi-capacity units. Use the superscript k=2 to denote a test 
with the unit operating at high capacity or full speed, k=1 to denote 
low capacity or minimum speed, and k=v to denote the intermediate speed.
    d. For mobile home and space-constrained ducted coil-only system 
tests, decrease Qc\k\(T) by
[GRAPHIC] [TIFF OMITTED] TR05JA17.158

where Vis is the average measured indoor air volume rate 
expressed in units of cubic feet per minute of standard air (scfm).

tests, decrease Qc\k\(T) by

    e. For air conditioners and heat pumps having a constant-air-volume-

if the average of the measured external static pressures exceeds the 
applicable sections 3.1.4 minimum (or target) external static pressure 
([Delta]Pmin) by 0.03 inches of water or more.
    (1) Measure the average power consumption of the indoor blower motor 
(Efan,1) and record the corresponding external static 
pressure ([Delta]P1) during or immediately following the 30-
minute interval used for determining capacity.
    (2) After completing the 30-minute interval and while maintaining 
the same test conditions, adjust the exhaust fan of the airflow 
measuring apparatus until the external static pressure increases to 
approximately [Delta]P1 + ([Delta]P1 - 
[Delta]Pmin).
    (3) After re-establishing steady readings of the fan motor power and 
external static pressure, determine average values for the indoor blower 
power (Efan,2) and the external static pressure 
([Delta]P2) by making measurements over a 5-minute interval.
    (4) Approximate the average power consumption of the indoor blower 
motor at [Delta]Pmin using linear extrapolation:

by the quantity (Efan,1 - Efan,min), when 
expressed on a Btu/h basis. Decrease the total electrical power, 
Ec\k\(T), by the same fan power difference, now expressed in 
watts.

  3.4 Test Procedures for the Steady-State Dry-Coil Cooling-Mode Tests 
     (the C, C1, C2, and G1 Tests)

    a. Except for the modifications noted in this section, conduct the 
steady-state dry coil cooling mode tests as specified in section 3.3 of 
this appendix for wet coil tests. Prior to recording data during the 
steady-state dry coil test, operate the unit at least one hour after 
achieving dry coil conditions. Drain the drain pan and plug the drain 
opening. Thereafter, the drain pan should remain completely dry.
    b. Denote the resulting total space cooling capacity and electrical 
power derived from the test as Qss,dry and 
Ess,dry. With regard to a section 3.3 deviation, do not 
adjust Qss,dry for duct losses (i.e., do not apply section 
7.3.3.3 of ANSI/ASHRAE 37-2009). In preparing for the section 3.5 cyclic 
tests of this appendix, record the average indoor-side air volume rate, 
Vi, specific heat of the air, Cp,a (expressed on dry air basis), 
specific volume of the air at the nozzles, v[min]n, humidity 
ratio at the nozzles, Wn, and either pressure difference or 
velocity pressure for the flow nozzles. For units having a variable-
speed indoor blower (that provides either a constant or variable air 
volume rate) that will or may be tested during the cyclic dry coil 
cooling mode test with the indoor blower turned off (see section 3.5 of 
this appendix), include the electrical power used by the indoor blower 
motor among the recorded parameters from the 30-minute test.
    c. If the temperature sensors used to provide the primary 
measurement of the indoor-side dry bulb temperature difference during 
the steady-state dry-coil test and the subsequent cyclic dry-coil test 
are different, include measurements of the latter sensors among the 
regularly sampled data. Beginning at the start of the 30-minute data 
collection period, measure and compute the indoor-side air dry-bulb 
temperature difference using both sets of instrumentation, [Delta]T (Set 
SS) and [Delta]T (Set CYC), for each equally spaced data sample. If 
using a consistent data sampling rate that is less than 1

[[Page 581]]

minute, calculate and record minutely averages for the two temperature 
differences. If using a consistent sampling rate of one minute or more, 
calculate and record the two temperature differences from each data 
sample. After having recorded the seventh (i=7) set of temperature 
differences, calculate the following ratio using the first seven sets of 
values:
[GRAPHIC] [TIFF OMITTED] TR05JA17.161

Each time a subsequent set of temperature differences is recorded (if 
sampling more frequently than every 5 minutes), calculate FCD using the 
most recent seven sets of values. Continue these calculations until the 
30-minute period is completed or until a value for FCD is calculated 
that falls outside the allowable range of 0.94-1.06. If the latter 
occurs, immediately suspend the test and identify the cause for the 
disparity in the two temperature difference measurements. Recalibration 
of one or both sets of instrumentation may be required. If all the 
values for FCD are within the allowable range, save the final value of 
the ratio from the 30-minute test as FCD*. If the temperature sensors 
used to provide the primary measurement of the indoor-side dry bulb 
temperature difference during the steady-state dry-coil test and the 
subsequent cyclic dry-coil test are the same, set FCD*= 1.

 3.5 Test Procedures for the Cyclic Dry-Coil Cooling-Mode Tests (the D, 
         D1, D2, and I1 Tests)

    After completing the steady-state dry-coil test, remove the outdoor 
air enthalpy method test apparatus, if connected, and begin manual OFF/
ON cycling of the unit's compressor. The test set-up should otherwise be 
identical to the set-up used during the steady-state dry coil test. When 
testing heat pumps, leave the reversing valve during the compressor OFF 
cycles in the same position as used for the compressor ON cycles, unless 
automatically changed by the controls of the unit. For units having a 
variable-speed indoor blower, the manufacturer has the option of 
electing at the outset whether to conduct the cyclic test with the 
indoor blower enabled or disabled. Always revert to testing with the 
indoor blower disabled if cyclic testing with the fan enabled is 
unsuccessful.
    a. For all cyclic tests, the measured capacity must be adjusted for 
the thermal mass stored in devices and connections located between 
measured points. Follow the procedure outlined in section 7.4.3.4.5 of 
ASHRAE 116-2010 (incorporated by reference, see Sec. 430.3) to ensure 
any required measurements are taken.
    b. For units having a single-speed or two-capacity compressor, cycle 
the compressor OFF for 24 minutes and then ON for 6 minutes 
([Delta][tau]cyc,dry = 0.5 hours). For units having a 
variable-speed compressor, cycle the compressor OFF for 48 minutes and 
then ON for 12 minutes ([Delta][tau]cyc,dry = 1.0 hours). 
Repeat the OFF/ON compressor cycling pattern until the test is 
completed. Allow the controls of the unit to regulate cycling of the 
outdoor fan. If an upturned duct is used, measure the dry-bulb 
temperature at the inlet of the device at least once every minute and 
ensure that its test operating tolerance is within 1.0 [deg]F for each 
compressor OFF period.
    c. Sections 3.5.1 and 3.5.2 of this appendix specify airflow 
requirements through the indoor coil of ducted and non-ducted indoor 
units, respectively. In all cases, use the exhaust fan of the airflow 
measuring apparatus (covered under section 2.6 of this appendix) along 
with the indoor blower of the unit, if installed and operating, to 
approximate a step response in the indoor coil airflow. Regulate the 
exhaust fan to quickly obtain and then maintain the flow nozzle static 
pressure difference or velocity pressure at the same value as was 
measured during the steady-state dry coil test. The pressure difference 
or velocity pressure should be within 2 percent of the value from the 
steady-state dry coil test within 15 seconds after airflow initiation. 
For units having a variable-speed indoor blower that ramps when cycling 
on and/or off, use the exhaust fan of the airflow measuring apparatus to 
impose a step response that begins at the initiation of ramp up and ends 
at the termination of ramp down.
    d. For units having a variable-speed indoor blower, conduct the 
cyclic dry coil test using the pull-thru approach described below if any 
of the following occur when testing with the fan operating:
    (1) The test unit automatically cycles off;
    (2) Its blower motor reverses; or
    (3) The unit operates for more than 30 seconds at an external static 
pressure that is 0.1 inches of water or more higher than the value 
measured during the prior steady-state test.

[[Page 582]]

    For the pull-thru approach, disable the indoor blower and use the 
exhaust fan of the airflow measuring apparatus to generate the specified 
flow nozzles static pressure difference or velocity pressure. If the 
exhaust fan cannot deliver the required pressure difference because of 
resistance created by the unpowered indoor blower, temporarily remove 
the indoor blower.
    e. Conduct three complete compressor OFF/ON cycles with the test 
tolerances given in Table 10 satisfied. Calculate the degradation 
coefficient CD for each complete cycle. If all three 
CD values are within 0.02 of the average CD then 
stability has been achieved, use the highest CD value of 
these three. If stability has not been achieved, conduct additional 
cycles, up to a maximum of eight cycles, until stability has been 
achieved between three consecutive cycles. Once stability has been 
achieved, use the highest CD value of the three consecutive 
cycles that establish stability. If stability has not been achieved 
after eight cycles, use the highest CD from cycle one through 
cycle eight, or the default CD, whichever is lower.
    f. With regard to the Table 10 parameters, continuously record the 
dry-bulb temperature of the air entering the indoor and outdoor coils 
during periods when air flows through the respective coils. Sample the 
water vapor content of the indoor coil inlet air at least every 2 
minutes during periods when air flows through the coil. Record external 
static pressure and the air volume rate indicator (either nozzle 
pressure difference or velocity pressure) at least every minute during 
the interval that air flows through the indoor coil. (These regular 
measurements of the airflow rate indicator are in addition to the 
required measurement at 15 seconds after flow initiation.) Sample the 
electrical voltage at least every 2 minutes beginning 30 seconds after 
compressor start-up. Continue until the compressor, the outdoor fan, and 
the indoor blower (if it is installed and operating) cycle off.
    g. For ducted units, continuously record the dry-bulb temperature of 
the air entering (as noted above) and leaving the indoor coil. Or if 
using a thermopile, continuously record the difference between these two 
temperatures during the interval that air flows through the indoor coil. 
For non-ducted units, make the same dry-bulb temperature measurements 
beginning when the compressor cycles on and ending when indoor coil 
airflow ceases.
    h. Integrate the electrical power over complete cycles of length 
[Delta][tau]cyc,dry. For ducted blower coil systems tested 
with the unit's indoor blower operating for the cycling test, integrate 
electrical power from indoor blower OFF to indoor blower OFF. For all 
other ducted units and for non-ducted units, integrate electrical power 
from compressor OFF to compressor OFF. (Some cyclic tests will use the 
same data collection intervals to determine the electrical energy and 
the total space cooling. For other units, terminate data collection used 
to determine the electrical energy before terminating data collection 
used to determine total space cooling.)

Tal([tau]) = dry bulb temperature of the air entering the 
          indoor coil at time [tau], [deg]F.

Ta2([tau]) = dry bulb temperature of the air leaving the 
          indoor coil at time [tau], [deg]F.

[tau]1 = for ducted units, the elapsed time when airflow is 
          initiated through the indoor coil; for non-ducted units, the 
          elapsed time when the compressor is cycled on, hr.

[tau]2 = the elapsed time when indoor coil airflow ceases, 
          hr.

    Adjust the total space cooling delivered, qcyc,dry, 
according to calculation method outlined in section 7.4.3.4.5 of ASHRAE 
116-2010 (incorporated by reference, see Sec. 430.3).

              3.5.1 Procedures When Testing Ducted Systems

    The automatic controls that are installed in the test unit must 
govern the OFF/ON cycling of the air moving equipment on the indoor side 
(exhaust fan of the airflow measuring apparatus and the indoor blower of 
the test unit). For ducted coil-only systems rated based on using a fan 
time-delay relay, control the indoor coil airflow according to the OFF 
delay listed by the manufacturer in the certification report. For ducted 
units having a variable-speed indoor blower that has been disabled (and 
possibly removed), start and stop the indoor airflow at the same 
instances as if the fan were enabled. For all other ducted coil-only 
systems, cycle the indoor coil airflow in unison with the cycling of the 
compressor. If air damper boxes are used, close them on the inlet and 
outlet side during the OFF period. Airflow through the indoor coil 
should stop within 3 seconds after the automatic controls of the test 
unit (act to) de-energize the indoor blower. For mobile home and space-
constrained ducted coil-only systems increase ecyc,dry by the 
quantity,

where Vis is the average indoor air volume rate from the 
section 3.4 dry coil steady-state test and is expressed in units of 
cubic feet per minute of standard air (scfm). For ducted non-mobile, 
non-space-constrained home coil-only units increase ecyc,dry 
by the quantity,
[GRAPHIC] [TIFF OMITTED] TR05JA17.165

[GRAPHIC] [TIFF OMITTED] TR05JA17.166

where Vis is the average indoor air volume rate from the 
section 3.4 dry coil steady-state test and is expressed in units of 
cubic feet per minute of standard air (scfm). For units having a 
variable-speed indoor blower that is disabled during the cyclic test, 
increase ecyc,dry and decrease qcyc,dry based on:
    a. The product of [[tau]2 - [tau] 1] and the 
indoor blower power measured during or following the dry coil steady-
state test; or,
    b. The following algorithm if the indoor blower ramps its speed when 
cycling.
    (1) Measure the electrical power consumed by the variable-speed 
indoor blower at a minimum of three operating conditions: at the speed/
air volume rate/external static pressure that was measured during the 
steady-state test, at operating conditions associated with the midpoint 
of the ramp-up interval, and at conditions associated with the midpoint 
of the ramp-down interval. For these

[[Page 584]]

measurements, the tolerances on the airflow volume or the external 
static pressure are the same as required for the section 3.4 steady-
state test.
    (2) For each case, determine the fan power from measurements made 
over a minimum of 5 minutes.
    (3) Approximate the electrical energy consumption of the indoor 
blower if it had operated during the cyclic test using all three power 
measurements. Assume a linear profile during the ramp intervals. The 
manufacturer must provide the durations of the ramp-up and ramp-down 
intervals. If the test setup instructions included with the unit by the 
manufacturer specifies a ramp interval that exceeds 45 seconds, use a 
45-second ramp interval nonetheless when estimating the fan energy.

          3.5.2 Procedures When Testing Non-Ducted Indoor Units

    Do not use airflow prevention devices when conducting cyclic tests 
on non-ducted indoor units. Until the last OFF/ON compressor cycle, 
airflow through the indoor coil must cycle off and on in unison with the 
compressor. For the last OFF/ON compressor cycle--the one used to 
determine ecyc,dry and qcyc,dry--use the exhaust 
fan of the airflow measuring apparatus and the indoor blower of the test 
unit to have indoor airflow start 3 minutes prior to compressor cut-on 
and end three minutes after compressor cutoff. Subtract the electrical 
energy used by the indoor blower during the 3 minutes prior to 
compressor cut-on from the integrated electrical energy, 
ecyc,dry. Add the electrical energy used by the indoor blower 
during the 3 minutes after compressor cutoff to the integrated cooling 
capacity, qcyc,dry. For the case where the non-ducted indoor 
unit uses a variable-speed indoor blower which is disabled during the 
cyclic test, correct ecyc,dry and qcyc,dry using 
the same approach as prescribed in section 3.5.1 of this appendix for 
ducted units having a disabled variable-speed indoor blower.

      3.5.3 Cooling-Mode Cyclic-Degradation Coefficient Calculation

    Use the two dry-coil tests to determine the cooling-mode cyclic-
degradation coefficient, CD\c\. Append ``(k=2)'' to the 
coefficient if it corresponds to a two-capacity unit cycling at high 
capacity. If the two optional tests are conducted but yield a tested 
CD\c\ that exceeds the default CD\c\ or if the two 
optional tests are not conducted, assign CD\c\ the default 
value of 0.25 for variable-speed compressor systems and outdoor units 
with no match, and 0.20 for all other systems. The default value for 
two-capacity units cycling at high capacity, however, is the low-
capacity coefficient, i.e., CD\c\(k=2) = CD\c\. 
Evaluate CD\c\ using the above results and those from the 
section 3.4 dry-coil steady-state test.

  3.6 Heating Mode Tests for Different Types of Heat Pumps, Including 
                         Heating-Only Heat Pumps

 3.6.1 Tests for a Heat Pump Having a Single-Speed Compressor and Fixed 
                         Heating Air Volume Rate

    This set of tests is for single-speed-compressor heat pumps that do 
not have a heating minimum air volume rate or a heating intermediate air 
volume rate that is different than the heating full load air volume 
rate. Conducting a very low temperature test (H4) is optional. Conduct 
the optional high temperature cyclic (H1C) test to determine the heating 
mode cyclic-degradation coefficient, CD\h\. If this optional 
test is conducted but yields a tested CD\h\ that exceeds the 
default CD\h\ or if the optional test is not conducted, 
assign CD\h\ the default value of 0.25. Test conditions for 
the five tests are specified in Table 11 of this section.

Indoor Blower Whose Capacity Modulation Correlates With Outdoor Dry Bulb 
               Temperature or (2) Multiple Indoor Blowers

    Conduct five tests: Two high temperature tests (H12 and 
H11), one frost accumulation test (H22), and two 
low temperature tests (H32 and H31). Conducting an 
additional frost accumulation test (H21) and a very low 
temperature test (H42) is optional. Conduct the optional high 
temperature cyclic (H1C1) test to determine the heating mode 
cyclic-degradation coefficient, CD\h\. If this optional test 
is conducted but yields a tested CD\h\ that exceeds the 
default CD\h\ or if the optional test is not conducted, 
assign CD\h\ the default value of 0.25. Test conditions for 
the seven tests are specified in Table 12. If the optional 
H21 test is not performed, use the following equations to 
approximate the capacity and electrical power of the heat pump at the 
H21 test conditions:

   3.6.3 Tests for a Heat Pump Having a Two-Capacity Compressor (see 
  Section 1.2 of This Appendix, Definitions), Including Two-Capacity, 
   Northern Heat Pumps (see Section 1.2 of This Appendix, Definitions)

    a. Conduct one maximum temperature test (H01), two high 
temperature tests (H12 and H11), one frost 
accumulation test (H22), and one low temperature test 
(H32). Conducting a very low temperature test 
(H42) is optional. Conduct an additional frost accumulation 
test (H21) and low temperature test (H31) if both 
of the following conditions exist:
    (1) Knowledge of the heat pump's capacity and electrical power at 
low compressor capacity for outdoor temperatures of 37 [deg]F and less 
is needed to complete the section 4.2.3 of this appendix seasonal 
performance calculations; and
    (2) The heat pump's controls allow low-capacity operation at outdoor 
temperatures of 37 [deg]F and less.
    If the two conditions in a.(1) and a.(2) of this section are met, an 
alternative to conducting the H21 frost accumulation is to 
use the following equations to approximate the capacity and electrical 
power:

appendix. Determine the quantities Qhk=1 (17) and Ehk=1 (17) from the 
H31 test and evaluate them according to section 3.10 of this 
appendix.
    b. Conduct the optional high temperature cyclic test 
(H1C1) to determine the heating mode cyclic-degradation 
coefficient, CDh. If this optional test is 
conducted but yields a tested CDh that exceeds the 
default CDh or if the optional test is not 
conducted, assign CDh the default value of 0.25. 
If a two-capacity heat pump locks out low capacity operation at lower 
outdoor temperatures, conduct the high temperature cyclic test 
(H1C2) to determine the high-capacity heating mode cyclic-
degradation coefficient, CDh (k=2). If this 
optional test at high capacity is conducted but yields a tested 
CDh (k = 2) that exceeds the default 
CDh (k = 2) or if the optional test is not 
conducted, assign CDh the default value. The 
default CDh (k=2) is the same value as determined 
or assigned for the low-capacity cyclic-degradation coefficient, 
CDh [or equivalently, CDh 
(k=1)]. Table 13 specifies test conditions for these nine tests.

     3.6.4 Tests for a Heat Pump Having a Variable-Speed Compressor

    a. Conduct one maximum temperature test (H01), two high 
temperature tests (H1N and H11), one frost 
accumulation test (H2V), and one low temperature test 
(H32). Conducting one or more of the following tests is 
optional: An additional high temperature test (H12), an 
additional frost accumulation test (H22), and a very low 
temperature test (H42). Conduct the optional high temperature 
cyclic (H1C1) test to determine the heating mode cyclic-
degradation coefficient, CDh. If this optional 
test is conducted but yields a tested CDh that 
exceeds the default CDh or if the optional test is 
not conducted, assign CDh the default value of 
0.25. Test conditions for the nine tests are specified in Table 14. The 
compressor shall operate at the same heating full speed, measured by RPM 
or power input frequency (Hz), as the maximum speed at which the system 
controls would operate the compressor in normal operation in 17 [deg]F 
ambient temperature, for the H12, H22 and 
H32 Tests. The compressor shall operate for the 
H1N test at the maximum speed at which the system controls 
would operate the compressor in normal operation in 47 [deg]F ambient 
temperature. The compressor shall operate at the same heating minimum 
speed, measured by RPM or power input frequency (Hz), for the 
H01, H1C1, and H11 Tests. Determine the 
heating intermediate compressor speed cited in Table 14 using the 
heating mode full and minimum compressors speeds and:

Where a tolerance of plus 5 percent or the next higher inverter 
frequency step from that calculated is allowed.
    b. If one of the high temperature tests (H12 or 
H1N) is conducted using the same compressor speed (RPM or 
power input frequency) as the H32 test, set the 47 [deg]F 
capacity and power input values used for calculation of HSPF2 equal to 
the measured values for that test:

Where:

Qhcalck=2(47) and Ehcalck=2(47) are the capacity 
          and power input representing full-speed operation at 47 [deg]F 
          for the HSPF2 calculations,

Qhk=2(47) is the capacity measured in the high temperature 
          test (H12 or H1N) which used the same 
          compressor speed as the H32 test, and
Ehk=2(47) is the power input measured in the high temperature 
          test (H12 or H1N) which used the same 
          compressor speed as the H32 test.
    Evaluate the quantities Qhk=2(47) and from 
Ehk=2(47) according to section 3.7.
    Otherwise (if no high temperature test is conducted using the same 
speed (RPM or power input frequency) as the H32 test), 
calculate the 47 [deg]F capacity and power input values used for 
calculation of HSPF2 as follows:

Where:

Qhcalck=2(47) and Ehcalck=2(47) are the capacity 
          and power input representing full-speed operation at 47 [deg]F 
          for the HSPF2 calculations,
Qhk=2(17) is the capacity measured in the H32 
          test,
Ehk=2(17) is the power input measured in the H32 
          test,

CSF is the capacity slope factor, equal to 0.0204/ [deg]F for split 
          systems and 0.0262/ [deg]F for single-package systems, and

PSF is the Power Slope Factor, equal to 0.00455/ [deg]F.

    c. If the H22 test is not done, use the following

    e. For multiple-split heat pumps (only), the following procedures 
supersede the above requirements. For all Table 14 tests specified for a 
minimum compressor speed, turn off at least one indoor unit. The 
manufacturer shall designate the particular indoor unit(s) that is 
turned off. The manufacturer must also specify the compressor speed used 
for the Table 14 H2V test, a heating mode intermediate 
compressor speed that falls within \1/4\ and \3/4\ of the difference 
between the full and minimum heating mode speeds. The manufacturer 
should prescribe an intermediate speed that is expected to yield the 
highest COP for the given H2V test conditions and bracketed 
compressor speed range. The manufacturer can designate that one or more 
specific indoor units are turned off for the H2V test.

 3.6.5 Additional Test for a Heat Pump Having a Heat Comfort Controller

    Test any heat pump that has a heat comfort controller (see section 
1.2 of this appendix, Definitions) according to section 3.6.1, 3.6.2, or 
3.6.3, whichever applies, with the heat comfort controller disabled. 
Additionally, conduct the abbreviated test described in section 3.1.9 of 
this appendix with the heat comfort controller active to determine the 
system's maximum supply air temperature. ( Note: heat pumps having a 
variable-speed compressor and a heat comfort controller are not covered 
in the test procedure at this time.)

 3.6.6 Heating Mode Tests for Northern Heat Pumps with Triple-Capacity 
                               Compressors

    Test triple-capacity, northern heat pumps for the heating mode as 
follows:
    a. Conduct one maximum temperature test (H01), two high 
temperature tests (H12 and H11), one frost 
accumulation test (H22), two low temperature tests 
(H32, H33), and one very low temperature test 
(H43). Conduct an additional frost accumulation test 
(H21) and low temperature test (H31) if both of 
the following conditions exist: (1) Knowledge of the heat pump's 
capacity and electrical power at low compressor capacity for outdoor 
temperatures of 37 [deg]F and less is needed to complete the section 
4.2.6 seasonal performance calculations; and (2) the heat pump's 
controls allow low capacity operation at outdoor temperatures of 37 
[deg]F and less. If the above two conditions are met, an alternative to 
conducting the H21 frost accumulation test to determine 
Qhk=1(35) and Ehk=1(35) is to use the following equations to approximate 
this capacity and electrical power:

[[Page 590]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.178

    In evaluating the above equations, determine the quantities 
Qhk=1(47) from the H11 test and evaluate them according to 
section 3.7 of this appendix. Determine the quantities Qhk=1(17) and 
Ehk=1(17) from the H31 test and evaluate them according to 
section 3.10 of this appendix. Use the paired values of Qhk=1(35) and 
Ehk=1(35) derived from conducting the H21 frost accumulation 
test and evaluated as specified in section 3.9.1 of this appendix or use 
the paired values calculated using the above default equations, 
whichever contribute to a higher Region IV HSPF2 based on the DHRmin.
    b. Conducting a frost accumulation test (H23) with the 
heat pump operating at its booster capacity is optional. If this 
optional test is not conducted, determine Qhk=3(35) and 
Ehk=3(35) using the following equations to approximate this 
capacity and electrical power:
[GRAPHIC] [TIFF OMITTED] TR05JA17.179

Where:
[GRAPHIC] [TIFF OMITTED] TR05JA17.180

    Determine the quantities Qhk=2(47) and 
Ehk=2(47) from the H12 test and evaluate them 
according to section 3.7 of this appendix. Determine the quantities 
Qhk=2(35) and Ehk=2(35) from the H22 
test and evaluate them according to section 3.9.1 of this appendix. 
Determine the quantities Qhk=2(17) and Ehk=2(17) 
from the H32 test, determine the quantities 
Qhk=3(17) and Ehk=3(17) from the H33 
test, and determine the quantities Qhk=3(5) and 
Ehk=3(5) from the H43 test. Evaluate all six 
quantities according to section 3.10 of this appendix. Use the paired 
values of Qhk=3(35) and Ehk=3(35) derived from 
conducting the H23 frost accumulation test and calculated as 
specified in section 3.9.1 of this appendix or use the paired values 
calculated using the above default equations, whichever contribute to a 
higher Region IV HSPF2 based on the DHRmin.
    c. Conduct the optional high temperature cyclic test 
(H1C1) to determine the heating mode cyclic-degradation 
coefficient, CD\h\. A default value for CD\h\ of 
0.25 may be used in lieu of conducting the cyclic. If a triple-capacity 
heat pump locks out low capacity operation at lower outdoor 
temperatures, conduct the high temperature cyclic test (H1C2) 
to determine the high capacity heating mode cyclic-degradation 
coefficient, CD\h\ (k=2). The default CD\h\ (k=2) 
is the same value as determined or assigned for the low-capacity cyclic-
degradation coefficient, CD\h\ [or equivalently, 
CD\h\ (k=1)]. Finally, if a triple-capacity heat pump locks 
out both low and high capacity operation at the lowest outdoor 
temperatures, conduct the low temperature cyclic test (H3C3) 
to determine the booster-capacity heating mode cyclic-degradation 
coefficient, CD\h\ (k=3). The default CD\h\ (k=3)

[[Page 591]]

is the same value as determined or assigned for the high capacity 
cyclic-degradation coefficient, CD\h\ [or equivalently, 
CD\h\ (k=2)]. Table 15 specifies test conditions for all 13 
tests.

3.6.7 Tests for a Heat Pump Having a Single Indoor Unit Having Multiple 
Indoor Blowers and Offering Two Stages of Compressor Modulation. Conduct 
   the Heating Mode Tests Specified in Section 3.6.3 of this Appendix

   3.7 Test Procedures for Steady-State Maximum Temperature and High 
Temperature Heating Mode Tests (the H01, H1, H12, 
                H11, and H1N tests)

    a. For the pretest interval, operate the test room reconditioning 
apparatus and the heat pump until equilibrium conditions are maintained 
for at least 30 minutes at the specified section 3.6 test conditions. 
Use the exhaust fan of the airflow measuring apparatus and, if 
installed, the indoor blower of the heat pump to obtain and then 
maintain the indoor air volume rate and/or the external static pressure 
specified for the particular test. Continuously record the dry-bulb 
temperature of the air entering the indoor coil, and the dry-bulb 
temperature and water vapor content of the air entering the outdoor 
coil. Refer to section 3.11 of this appendix for additional requirements 
that depend on the selected secondary test method. After satisfying the 
pretest equilibrium requirements, make the measurements specified in 
Table 3 of ANSI/ASHRAE 37-2009 (incorporated by reference, see Sec. 
430.3) for the indoor air enthalpy method and the user-selected 
secondary method. Make said Table 3 measurements at equal intervals that 
span 5 minutes or less. Continue data sampling until a 30-minute period 
(e.g., seven consecutive 5-minute samples) is reached where the test 
tolerances specified in Table 16 are satisfied. For those continuously 
recorded parameters, use the entire data set for the 30-minute interval 
when evaluating Table 16 compliance. Determine the average electrical 
power consumption of the heat pump over the same 30-minute interval.

    b. Calculate indoor-side total heating capacity as specified in 
sections 7.3.4.1 and 7.3.4.3 of ANSI/ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3). To calculate capacity, use the averages of 
the measurements (e.g. inlet and outlet dry bulb temperatures measured 
at the psychrometers) that are continuously recorded for the same 30-
minute interval used as described above to evaluate compliance with test 
tolerances. Do not adjust the parameters used in calculating capacity 
for the permitted variations in test conditions. Assign the average 
space heating capacity and electrical power over the 30-minute data 
collection interval to the variables Qh\k\ and Eh\k\(T) respectively. 
The ``T'' and superscripted ``k'' are the same as described in section 
3.3 of this appendix. Additionally, for the heating mode, use the 
superscript to denote results from the optional H1N test, if 
conducted.
    c. For mobile home and space-constrained coil-only system heat 
pumps, increase Qh\k\(T) by
[GRAPHIC] [TIFF OMITTED] TR05JA17.181

where Vis is the average measured indoor air volume rate 
expressed in units of cubic feet per minute of standard air (scfm).
    For non-mobile home, non-space-constrained coil-only system heat 
pumps, increase Qh\k\(T) by

[[Page 593]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.182

where Vis is the average measured indoor air volume rate 
expressed in units of cubic feet per minute of standard air (scfm). 
During the 30-minute data collection interval of a high temperature 
test, pay attention to preventing a defrost cycle. Prior to this time, 
allow the heat pump to perform a defrost cycle if automatically 
initiated by its own controls. As in all cases, wait for the heat pump's 
defrost controls to automatically terminate the defrost cycle. Heat 
pumps that undergo a defrost cycle should operate in the heating mode 
for at least 10 minutes after defrost termination prior to beginning the 
30-minute data collection interval. For some heat pumps, frost may 
accumulate on the outdoor coil during a high temperature test. If the 
indoor coil leaving air temperature or the difference between the 
leaving and entering air temperatures decreases by more than 1.5 [deg]F 
over the 30-minute data collection interval, then do not use the 
collected data to determine capacity. Instead, initiate a defrost cycle. 
Begin collecting data no sooner than 10 minutes after defrost 
termination. Collect 30 minutes of new data during which the Table 16 
test tolerances are satisfied. In this case, use only the results from 
the second 30-minute data collection interval to evaluate Qh\k\(47) and 
Eh\k\(47).
    d. If conducting the cyclic heating mode test, which is described in 
section 3.8 of this appendix, record the average indoor-side air volume 
rate, Vi, specific heat of the air, Cp,a (expressed on dry 
air basis), specific volume of the air at the nozzles, 
vn[min] (or vn), humidity ratio at the nozzles, 
Wn, and either pressure difference or velocity pressure for 
the flow nozzles. If either or both of the below criteria apply, 
determine the average, steady-state, electrical power consumption of the 
indoor blower motor (Efan,1):
    (1) The section 3.8 cyclic test will be conducted and the heat pump 
has a variable-speed indoor blower that is expected to be disabled 
during the cyclic test; or
    (2) The heat pump has a (variable-speed) constant-air volume-rate 
indoor blower and during the steady-state test the average external 
static pressure ([Delta]P1) exceeds the applicable section 
3.1.4.4 minimum (or targeted) external static pressure 
([Delta]Pmin) by 0.03 inches of water or more.
    Determine Efan,1 by making measurements during the 30-
minute data collection interval, or immediately following the test and 
prior to changing the test conditions. When the above ``2'' criteria 
applies, conduct the following four steps after determining 
Efan,1 (which corresponds to [Delta]P1):
    (i) While maintaining the same test conditions, adjust the exhaust 
fan of the airflow measuring apparatus until the external static 
pressure increases to approximately [Delta]P1 + 
([Delta]P1 - [Delta]Pmin).
    (ii) After re-establishing steady readings for fan motor power and 
external static pressure, determine average values for the indoor blower 
power (Efan,2) and the external static pressure 
([Delta]P2) by making measurements over a 5-minute interval.
    (iii) Approximate the average power consumption of the indoor blower 
motor if the 30-minute test had been conducted at [Delta]Pmin 
using linear extrapolation:
[GRAPHIC] [TIFF OMITTED] TR05JA17.183

    (iv) Decrease the total space heating capacity, Qh\k\(T), by the 
quantity (Efan,1 - Efan,min), when expressed on a 
Btu/h basis. Decrease the total electrical power, Eh\k\(T) by the same 
fan power difference, now expressed in watts.
    e. If the temperature sensors used to provide the primary 
measurement of the indoor-

[[Page 594]]

side dry bulb temperature difference during the steady-state dry-coil 
test and the subsequent cyclic dry-coil test are different, include 
measurements of the latter sensors among the regularly sampled data. 
Beginning at the start of the 30-minute data collection period, measure 
and compute the indoor-side air dry-bulb temperature difference using 
both sets of instrumentation, [Delta]T (Set SS) and [Delta]T (Set CYC), 
for each equally spaced data sample. If using a consistent data sampling 
rate that is less than 1 minute, calculate and record minutely averages 
for the two temperature differences. If using a consistent sampling rate 
of one minute or more, calculate and record the two temperature 
differences from each data sample. After having recorded the seventh 
(i=7) set of temperature differences, calculate the following ratio 
using the first seven sets of values:
[GRAPHIC] [TIFF OMITTED] TR05JA17.184

Each time a subsequent set of temperature differences is recorded (if 
sampling more frequently than every 5 minutes), calculate FCD 
using the most recent seven sets of values. Continue these calculations 
until the 30-minute period is completed or until a value for 
FCD is calculated that falls outside the allowable range of 
0.94-1.06. If the latter occurs, immediately suspend the test and 
identify the cause for the disparity in the two temperature difference 
measurements. Recalibration of one or both sets of instrumentation may 
be required. If all the values for FCD are within the 
allowable range, save the final value of the ratio from the 30-minute 
test as FCD*. If the temperature sensors used to provide the 
primary measurement of the indoor-side dry bulb temperature difference 
during the steady-state dry-coil test and the subsequent cyclic dry-coil 
test are the same, set FCD*= 1.

       3.8 Test Procedures for the Cyclic Heating Mode Tests (the 
    H0C1, H1C, H1C1 and H1C2 Tests).

    a. Except as noted below, conduct the cyclic heating mode test as 
specified in section 3.5 of this appendix. As adapted to the heating 
mode, replace section 3.5 references to ``the steady-state dry coil 
test'' with ``the heating mode steady-state test conducted at the same 
test conditions as the cyclic heating mode test.'' Use the test 
tolerances in Table 17 rather than Table 10. Record the outdoor coil 
entering wet-bulb temperature according to the requirements given in 
section 3.5 of this appendix for the outdoor coil entering dry-bulb 
temperature. Drop the subscript ``dry'' used in variables cited in 
section 3.5 of this appendix when referring to quantities from the 
cyclic heating mode test. If available, use electric resistance heaters 
(see section 2.1 of this appendix) to minimize the variation in the 
inlet air temperature. Determine the total space heating delivered 
during the cyclic heating test, qcyc, as specified in section 
3.5 of this appendix except for making the following changes:
    (1) When evaluating Equation 3.5-1, use the values of Vi, 
Cp,a,vn[min], (or vn), and 
Wn that were recorded during the section 3.7 steady-state 
test conducted at the same test conditions.
    (2) Calculate
    [GRAPHIC] [TIFF OMITTED] TR05JA17.185
    
where FCD* is the value recorded during the section 3.7 
steady-state test conducted at the same test condition.
    b. For ducted coil-only system heat pumps (excluding the special 
case where a variable-speed fan is temporarily removed), increase 
qcyc by the amount calculated using Equation 3.5-3. 
Additionally, increase ecyc by the amount calculated using 
Equation 3.5-2. In making these calculations, use the average indoor air 
volume rate (Vis) determined from the section 3.7 steady-
state heating mode test conducted at the same test conditions.
    c. For non-ducted heat pumps, subtract the electrical energy used by 
the indoor blower during the 3 minutes after compressor cutoff from the 
non-ducted heat pump's integrated heating capacity, qcyc.
    d. If a heat pump defrost cycle is manually or automatically 
initiated immediately prior to or during the OFF/ON cycling, operate the 
heat pump continuously until 10 minutes

[[Page 595]]

after defrost termination. After that, begin cycling the heat pump 
immediately or delay until the specified test conditions have been re-
established. Pay attention to preventing defrosts after beginning the 
cycling process. For heat pumps that cycle off the indoor blower during 
a defrost cycle, make no effort here to restrict the air movement 
through the indoor coil while the fan is off. Resume the OFF/ON cycling 
while conducting a minimum of two complete compressor OFF/ON cycles 
before determining qcyc and ecyc.

      3.8.1 Heating Mode Cyclic-Degradation Coefficient Calculation

    Use the results from the required cyclic test and the required 
steady-state test that were conducted at the same test conditions to 
determine the heating mode cyclic-degradation coefficient CDh. Add 
``(k=2)'' to the coefficient if it corresponds to a two-capacity unit 
cycling at high capacity. For the below calculation of the heating mode 
cyclic degradation coefficient, do not include the duct loss correction 
from section 7.3.3.3 of ANSI/ASHRAE 37-2009 (incorporated by reference, 
see Sec. 430.3) in determining Qh\k\(Tcyc) (or 
qcyc). If the optional cyclic test is conducted but yields a 
tested CDh that exceeds the default CDh or if the optional test is not 
conducted, assign CDh the default value of 0.25. The default value for 
two-capacity units cycling at high capacity, however, is the low-
capacity coefficient, i.e., CDh (k=2) = CDh. The tested CDh is 
calculated as follows:

the average coefficient of performance during the steady-state heating 
mode test conducted at the same test conditions--i.e., same outdoor dry 
bulb temperature, Tcyc, and speed/capacity, k, if 
applicable--as specified for the cyclic heating mode test, 
dimensionless.

the heating load factor, dimensionless.

Tcyc = the nominal outdoor temperature at which the cyclic 
          heating mode test is conducted, 62 or 47 [deg]F.

[Delta][tau]cyc = the duration of the OFF/ON intervals; 0.5 
          hours when testing a heat pump having a single-speed or two-
          capacity compressor and 1.0 hour when testing a heat pump 
          having a variable-speed compressor.

    Round the calculated value for CDh to the nearest 0.01. If CDh is 
negative, then set it equal to zero.

 3.9 Test Procedures for Frost Accumulation Heating Mode Tests (the H2, 
       H22, H2V, and H21 Tests).

    a. Confirm that the defrost controls of the heat pump are set as 
specified in section 2.2.1 of this appendix. Operate the test room 
reconditioning apparatus and the heat pump for at least 30 minutes at 
the specified section 3.6 test conditions before starting the 
``preliminary'' test period. The preliminary test period must 
immediately precede the ``official'' test period, which is the heating 
and defrost interval over which data are collected for evaluating 
average space heating capacity and average electrical power consumption.
    b. For heat pumps containing defrost controls which are likely to 
cause defrosts at intervals less than one hour, the preliminary test 
period starts at the termination of an automatic defrost cycle and ends 
at the termination of the next occurring automatic defrost cycle. For 
heat pumps containing defrost controls which are likely to cause 
defrosts at intervals exceeding one hour, the preliminary test period 
must consist of a heating interval lasting at least one hour followed by 
a defrost cycle that is either manually or automatically initiated. In 
all cases, the heat pump's own controls must govern when a defrost cycle 
terminates.
    c. The official test period begins when the preliminary test period 
ends, at defrost termination. The official test period ends at the 
termination of the next occurring automatic defrost cycle. When testing 
a heat pump that uses a time-adaptive defrost control system (see 
section 1.2 of this appendix, Definitions), however, manually initiate 
the defrost cycle that ends the official test period at the instant 
indicated by instructions provided by the manufacturer. If the heat pump 
has not undergone a defrost after 6 hours, immediately conclude the test 
and use the results from the full 6-hour period to calculate the average 
space heating capacity and average electrical power consumption.
    For heat pumps that turn the indoor blower off during the defrost 
cycle, take steps to cease forced airflow through the indoor coil and 
block the outlet duct whenever the heat pump's controls cycle off the 
indoor blower. If it is installed, use the outlet damper box described 
in section 2.5.4.1 of this appendix to affect the blocked outlet duct.
    d. Defrost termination occurs when the controls of the heat pump 
actuate the first change in converting from defrost operation to normal 
heating operation. Defrost initiation occurs when the controls of the 
heat pump first alter its normal heating operation in order to eliminate 
possible accumulations of frost on the outdoor coil.
    e. To constitute a valid frost accumulation test, satisfy the test 
tolerances specified in Table 18 during both the preliminary and 
official test periods. As noted in Table 18, test operating tolerances 
are specified for two sub-intervals:
    (1) When heating, except for the first 10 minutes after the 
termination of a defrost cycle (sub-interval H, as described in Table 
18) and
    (2) When defrosting, plus these same first 10 minutes after defrost 
termination (sub-interval D, as described in Table 18). Evaluate

[[Page 597]]

compliance with Table 18 test condition tolerances and the majority of 
the test operating tolerances using the averages from measurements 
recorded only during sub-interval H. Continuously record the dry bulb 
temperature of the air entering the indoor coil, and the dry bulb 
temperature and water vapor content of the air entering the outdoor 
coil. Sample the remaining parameters listed in Table 18 at equal 
intervals that span 5 minutes or less.
    f. For the official test period, collect and use the following data 
to calculate average space heating capacity and electrical power. During 
heating and defrosting intervals when the controls of the heat pump have 
the indoor blower on, continuously record the dry-bulb temperature of 
the air entering (as noted above) and leaving the indoor coil. If using 
a thermopile, continuously record the difference between the leaving and 
entering dry-bulb temperatures during the interval(s) that air flows 
through the indoor coil. For coil-only system heat pumps, determine the 
corresponding cumulative time (in hours) of indoor coil airflow, 
[Delta][tau]a. Sample measurements used in calculating the 
air volume rate (refer to sections 7.7.2.1 and 7.7.2.2 of ANSI/ASHRAE 
37-2009) at equal intervals that span 10 minutes or less. (Note: In the 
first printing of ANSI/ASHRAE 37-2009, the second IP equation for 
Qmi should read:) Record the electrical energy consumed, 
expressed in watt-hours, from defrost termination to defrost 
termination, eDEF\k\(35), as well as the corresponding 
elapsed time in hours, [Delta][tau]FR.

 3.9.1 Average Space Heating Capacity and Electrical Power Calculations

    a. Evaluate average space heating capacity, Qh\k\(35), when 
expressed in units of Btu per hour, using:
[GRAPHIC] [TIFF OMITTED] TR05JA17.190

where,
Vi = the average indoor air volume rate measured during sub-interval H, 
          cfm.
Cp,a = 0.24 + 0.444 [middot] Wn, the constant 
          pressure specific heat of the air-water vapor mixture that 
          flows through the indoor coil and is expressed on a dry air 
          basis, Btu/lbmda [middot] [deg]F.
vn[min] = specific volume of the air-water vapor mixture at 
          the nozzle, ft\3\/lbmmx.
Wn = humidity ratio of the air-water vapor mixture at the 
          nozzle, lbm of water vapor per lbm of dry air.
[Delta][tau]FR = [tau]2 - [tau]1, the 
          elapsed time from defrost termination to defrost termination, 
          hr.

[[Page 598]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.191

Tal([tau]) = dry bulb temperature of the air entering the 
          indoor coil at elapsed time [tau], [deg]F; only recorded when 
          indoor coil airflow occurs; assigned the value of zero during 
          periods (if any) where the indoor blower cycles off.
Ta2([tau]) = dry bulb temperature of the air leaving the 
          indoor coil at elapsed time [tau], [deg]F; only recorded when 
          indoor coil airflow occurs; assigned the value of zero during 
          periods (if any) where the indoor blower cycles off.
[tau]1 = the elapsed time when the defrost termination occurs 
          that begins the official test period, hr.
[tau]2 = the elapsed time when the next automatically 
          occurring defrost termination occurs, thus ending the official 
          test period, hr.
vn = specific volume of the dry air portion of the mixture 
          evaluated at the dry-bulb temperature, vapor content, and 
          barometric pressure existing at the nozzle, ft\3\ per lbm of 
          dry air.
    To account for the effect of duct losses between the outlet of the 
indoor unit and the section 2.5.4 dry-bulb temperature grid, adjust 
Qh\k\(35) in accordance with section 7.3.4.3 of ANSI/ASHRAE 37-2009 
(incorporated by reference, see Sec. 430.3).
    b. Evaluate average electrical power, Eh\k\(35), when expressed in 
units of watts, using:
[GRAPHIC] [TIFF OMITTED] TR05JA17.192

For mobile home and space-constrained coil-only system heat pumps, 
increase Qh\k\(35) by
[GRAPHIC] [TIFF OMITTED] TR05JA17.193

    where Vis is the average measured indoor air volume rate 
expressed in units of cubic feet per minute of standard air (scfm).
    For non-mobile home, non-space-constrained coil-only system heat 
pumps, increase Qh\k\(35) by

[[Page 599]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.194

where Vis is the average measured indoor air volume rate 
expressed in units of cubic feet per minute of standard air (scfm).

    c. For heat pumps having a constant-air-volume-rate indoor blower, 
the five additional steps listed below are required if the average of 
the external static pressures measured during sub-interval H exceeds the 
applicable section 3.1.4.4, 3.1.4.5, or 3.1.4.6 minimum (or targeted) 
external static pressure ([Delta]Pmin) by 0.03 inches of 
water or more:
    (1) Measure the average power consumption of the indoor blower motor 
(Efan,1) and record the corresponding external static 
pressure ([Delta]P1) during or immediately following the 
frost accumulation heating mode test. Make the measurement at a time 
when the heat pump is heating, except for the first 10 minutes after the 
termination of a defrost cycle.
    (2) After the frost accumulation heating mode test is completed and 
while maintaining the same test conditions, adjust the exhaust fan of 
the airflow measuring apparatus until the external static pressure 
increases to approximately [Delta]P1 + ([Delta]P1 
- [Delta]Pmin).
    (3) After re-establishing steady readings for the fan motor power 
and external static pressure, determine average values for the indoor 
blower power (Efan,2) and the external static pressure 
([Delta]P2) by making measurements over a 5-minute interval.
    (4) Approximate the average power consumption of the indoor blower 
motor had the frost accumulation heating mode test been conducted at 
[Delta]Pmin using linear extrapolation:
[GRAPHIC] [TIFF OMITTED] TR05JA17.195

    (5) Decrease the total heating capacity, Qh\k\(35), by the quantity 
[(Efan,1 - Efan,min)[middot] ([Delta][tau] 
a/[Delta][tau] FR], when expressed on a Btu/h 
basis. Decrease the total electrical power, Eh\k\(35), by the same 
quantity, now expressed in watts.

                       3.9.2 Demand Defrost Credit

    a. Assign the demand defrost credit, Fdef, that is used 
in section 4.2 of this appendix to the value of 1 in all cases except 
for heat pumps having a demand-defrost control system (see section 1.2 
of this appendix, Definitions). For such qualifying heat pumps, evaluate 
Fdef using,
[GRAPHIC] [TIFF OMITTED] TR05JA17.196

where:
[Delta][tau]def = the time between defrost terminations (in 
          hours) or 1.5, whichever is greater. Assign a value of 6 to 
          [Delta][tau]def if this limit is reached during a 
          frost accumulation test and the heat pump has not completed a 
          defrost cycle.
[Delta][tau]max = maximum time between defrosts as allowed by 
          the controls (in hours) or 12,

[[Page 600]]

          whichever is less, as provided in the certification report.

    b. For two-capacity heat pumps and for section 3.6.2 units, evaluate 
the above equation using the [Delta][tau]def that applies 
based on the frost accumulation test conducted at high capacity and/or 
at the heating full-load air volume rate. For variable-speed heat pumps, 
evaluate [Delta][tau]def based on the required frost 
accumulation test conducted at the intermediate compressor speed.

   3.10 Test Procedures for Steady-State Low Temperature and Very Low 
Temperature Heating Mode Tests (the H3, H32, H31, 
      H33, H4, H42, and H43 Tests)

    Except for the modifications noted in this section, conduct the low 
temperature and very low temperature heating mode tests using the same 
approach as specified in section 3.7 of this appendix for the maximum 
and high temperature tests. After satisfying the section 3.7 
requirements for the pretest interval but before beginning to collect 
data to determine the capacity and power input, conduct a defrost cycle. 
This defrost cycle may be manually or automatically initiated. Terminate 
the defrost sequence using the heat pump's defrost controls. Begin the 
30-minute data collection interval described in section 3.7 of this 
appendix, from which the capacity and power input are determined, no 
sooner than 10 minutes after defrost termination. Defrosts should be 
prevented over the 30-minute data collection interval.

       3.11 Additional Requirements for the Secondary Test Methods

 3.11.1 If Using the Outdoor Air Enthalpy Method as the Secondary Test 
                                 Method.

    a. For all cooling mode and heating mode tests, first conduct a test 
without the outdoor air-side test apparatus described in section 2.10.1 
of this appendix connected to the outdoor unit (``free outdoor air'' 
test).
    b. For the first section 3.2 steady-state cooling mode test and the 
first section 3.6 steady-state heating mode test, conduct a second test 
in which the outdoor-side apparatus is connected (``ducted outdoor air'' 
test). No other cooling mode or heating mode tests require the ducted 
outdoor air test so long as the unit operates the outdoor fan during all 
cooling mode steady-state tests at the same speed and all heating mode 
steady-state tests at the same speed. If using more than one outdoor fan 
speed for the cooling mode steady-state tests, however, conduct the 
ducted outdoor air test for each cooling mode test where a different fan 
speed is first used. This same requirement applies for the heating mode 
tests.

                     3.11.1.1 Free Outdoor Air Test

    a. For the free outdoor air test, connect the indoor air-side test 
apparatus to the indoor coil; do not connect the outdoor air-side test 
apparatus. Allow the test room reconditioning apparatus and the unit 
being tested to operate for at least one hour. After attaining 
equilibrium conditions, measure the following quantities at equal 
intervals that span 5 minutes or less:
    (1) The section 2.10.1 evaporator and condenser temperatures or 
pressures;
    (2) Parameters required according to the Indoor Air Enthalpy Method.
    Continue these measurements until a 30-minute period (e.g., seven 
consecutive 5-minute samples) is obtained where the Table 9 or Table 16, 
whichever applies, test tolerances are satisfied.
    b. For cases where a ducted outdoor air test is not required per 
section 3.11.1.b of this appendix, the free outdoor air test constitutes 
the ``official'' test for which validity is not based on comparison with 
a secondary test.
    c. For cases where a ducted outdoor air test is required per section 
3.11.1.b of this appendix, the following conditions must be met for the 
free outdoor air test to constitute a valid ``official'' test:
    (1) The energy balance specified in section 3.1.1 of this appendix 
is achieved for the ducted outdoor air test (i.e., compare the 
capacities determined using the indoor air enthalpy method and the 
outdoor air enthalpy method).
    (2) The capacities determined using the indoor air enthalpy method 
from the ducted outdoor air and free outdoor air tests must agree within 
2 percent.

                    3.11.1.2 Ducted Outdoor Air Test

    a. The test conditions and tolerances for the ducted outdoor air 
test are the same as specified for the official test, where the official 
test is the free outdoor air test described in section 3.11.1.1 of this 
appendix.
    b. After collecting 30 minutes of steady-state data during the free 
outdoor air test, connect the outdoor air-side test apparatus to the 
unit for the ducted outdoor air test. Adjust the exhaust fan of the 
outdoor airflow measuring apparatus until averages for the evaporator 
and condenser temperatures, or the saturated temperatures corresponding 
to the measured pressures, agree within 0.5 [deg]F 
of the averages achieved during the free outdoor air test. Collect 30 
minutes of steady-state data after re-establishing equilibrium 
conditions.
    c. During the ducted outdoor air test, at intervals of 5 minutes or 
less, measure the parameters required according to the indoor air 
enthalpy method and the outdoor air enthalpy method for the prescribed 
30 minutes.

[[Page 601]]

    d. For cooling mode ducted outdoor air tests, calculate capacity 
based on outdoor air-enthalpy measurements as specified in sections 
7.3.3.2 and 7.3.3.3 of ANSI/ASHRAE 37-2009 (incorporated by reference, 
see Sec. 430.3). For heating mode ducted tests, calculate heating 
capacity based on outdoor air-enthalpy measurements as specified in 
sections 7.3.4.2 and 7.3.3.4.3 of the same ANSI/ASHRAE Standard. Adjust 
the outdoor-side capacity according to section 7.3.3.4 of ANSI/ASHRAE 
37-2009 to account for line losses when testing split systems. As 
described in section 8.6.2 of ANSI/ASHRAE 37-2009, use the outdoor air 
volume rate as measured during the ducted outdoor air tests to calculate 
capacity for checking the agreement with the capacity calculated using 
the indoor air enthalpy method.

3.11.2 If Using the Compressor Calibration Method as the Secondary Test 
                                 Method

    a. Conduct separate calibration tests using a calorimeter to 
determine the refrigerant flow rate. Or for cases where the superheat of 
the refrigerant leaving the evaporator is less than 5 [deg]F, use the 
calorimeter to measure total capacity rather than refrigerant flow rate. 
Conduct these calibration tests at the same test conditions as specified 
for the tests in this appendix. Operate the unit for at least one hour 
or until obtaining equilibrium conditions before collecting data that 
will be used in determining the average refrigerant flow rate or total 
capacity. Sample the data at equal intervals that span 5 minutes or 
less. Determine average flow rate or average capacity from data sampled 
over a 30-minute period where the Table 9 (cooling) or the Table 16 
(heating) tolerances are satisfied. Otherwise, conduct the calibration 
tests according to sections 5, 6, 7, and 8 of ASHRAE 23.1-2010 
(incorporated by reference, see Sec. 430.3); sections 5, 6, 7, 8, 9, 
and 11 of ASHRAE 41.9-2011 (incorporated by reference, see Sec. 430.3); 
and section 7.4 of ANSI/ASHRAE 37-2009 (incorporated by reference, see 
Sec. 430.3).
    b. Calculate space cooling and space heating capacities using the 
compressor calibration method measurements as specified in section 7.4.5 
and 7.4.6 respectively, of ANSI/ASHRAE 37-2009.

 3.11.3 If Using the Refrigerant-Enthalpy Method as the Secondary Test 
                                 Method

    Conduct this secondary method according to section 7.5 of ANSI/
ASHRAE 37-2009. Calculate space cooling and heating capacities using the 
refrigerant-enthalpy method measurements as specified in sections 7.5.4 
and 7.5.5, respectively, of the same ANSI/ASHRAE Standard.

  3.12 Rounding of Space Conditioning Capacities for Reporting Purposes

    a. When reporting rated capacities, round them off as specified in 
Sec. 430.23 (for a single unit) and in 10 CFR 429.16 (for a sample).
    b. For the capacities used to perform the calculations in section 4 
of this appendix, however, round only to the nearest integer.

   3.13 Laboratory Testing To Determine Off Mode Average Power Ratings

    Voltage tolerances: As a percentage of reading, test operating 
tolerance must be 2.0 percent and test condition tolerance must be 1.5 
percent (see section 1.2 of this appendix for definitions of these 
tolerances).
    Conduct one of the following tests: If the central air conditioner 
or heat pump lacks a compressor crankcase heater, perform the test in 
section 3.13.1 of this appendix; if the central air conditioner or heat 
pump has a compressor crankcase heater that lacks controls and is not 
self-regulating, perform the test in section 3.13.1 of this appendix; if 
the central air conditioner or heat pump has a crankcase heater with a 
fixed power input controlled with a thermostat that measures ambient 
temperature and whose sensing element temperature is not affected by the 
heater, perform the test in section 3.13.1 of this appendix; if the 
central air conditioner or heat pump has a compressor crankcase heater 
equipped with self-regulating control or with controls for which the 
sensing element temperature is affected by the heater, perform the test 
in section 3.13.2 of this appendix.

   3.13.1 This Test Determines the Off Mode Average Power Rating for 
Central Air Conditioners and Heat Pumps That Lack a Compressor Crankcase 
Heater, or Have a Compressor Crankcase Heating System That Can Be Tested 
Without Control of Ambient Temperature During the Test. This Test Has No 
                     Ambient Condition Requirements

    a. Test Sample Set-up and Power Measurement: For coil-only systems, 
provide a furnace or modular blower that is compatible with the system 
to serve as an interface with the thermostat (if used for the test) and 
to provide low-voltage control circuit power. Make all control circuit 
connections between the furnace (or modular blower) and the outdoor unit 
as specified by the manufacturer's installation instructions. Measure 
power supplied to both the furnace (or modular blower) and power 
supplied to the outdoor unit. Alternatively, provide a compatible 
transformer to supply low-voltage control circuit power, as described in 
section 2.2.d of this appendix. Measure transformer power, either 
supplied to the primary winding or supplied by the secondary winding of 
the transformer, and power supplied to the

[[Page 602]]

outdoor unit. For blower coil and single-package systems, make all 
control circuit connections between components as specified by the 
manufacturer's installation instructions, and provide power and measure 
power supplied to all system components.
    b. Configure Controls: Configure the controls of the central air 
conditioner or heat pump so that it operates as if connected to a 
building thermostat that is set to the OFF position. Use a compatible 
building thermostat if necessary to achieve this configuration. For a 
thermostat-controlled crankcase heater with a fixed power input, bypass 
the crankcase heater thermostat if necessary to energize the heater.
    c. Measure P2x: If the unit has a crankcase heater time delay, make 
sure that time-delay function is disabled or wait until delay time has 
passed. Determine the average power from non-zero value data measured 
over a 5-minute interval of the non-operating central air conditioner or 
heat pump and designate the average power as P2x, the heating season 
total off mode power.
    d. Measure Px for coil-only split systems and for blower coil split 
systems for which a furnace or a modular blower is the designated air 
mover: Disconnect all low-voltage wiring for the outdoor components and 
outdoor controls from the low-voltage transformer. Determine the average 
power from non-zero value data measured over a 5-minute interval of the 
power supplied to the (remaining) low-voltage components of the central 
air conditioner or heat pump, or low-voltage power, Px. This power 
measurement does not include line power supplied to the outdoor unit. It 
is the line power supplied to the air mover, or, if a compatible 
transformer is used instead of an air mover, it is the line power 
supplied to the transformer primary coil. If a compatible transformer is 
used instead of an air mover and power output of the low-voltage 
secondary circuit is measured, Px is zero.
    e. Calculate P2: Set the number of compressors equal to the unit's 
number of single-stage compressors plus 1.75 times the unit's number of 
compressors that are not single-stage.
    For single-package systems and blower coil split systems for which 
the designated air mover is not a furnace or modular blower, divide the 
heating season total off mode power (P2x) by the number of compressors 
to calculate P2, the heating season per-compressor off mode power. Round 
P2 to the nearest watt. The expression for calculating P2 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.197

    For coil-only split systems and blower coil split systems for which 
a furnace or a modular blower is the designated air mover, subtract the 
low-voltage power (Px) from the heating season total off mode power (Px) 
and divide by the number of compressors to calculate P2, the heating 
season per-compressor off mode power. Round P2 to the nearest watt. The 
expression for calculating P2 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.198

    f. Shoulder-season per-compressor off mode power, P1: If the system 
does not have a crankcase heater, has a crankcase heater without 
controls that is not self-regulating, or has a value for the crankcase 
heater turn-on temperature (as certified to DOE) that is higher than 71 
[deg]F, P1 is equal to P2.
    Otherwise, de-energize the crankcase heater (by removing the 
thermostat bypass or otherwise disconnecting only the power supply to 
the crankcase heater) and repeat the measurement as described in section 
3.13.1.c of this appendix. Designate the measured average power as P1x, 
the shoulder season total off mode power.
    Determine the number of compressors as described in section 3.13.1.e 
of this appendix.
    For single-package systems and blower coil systems for which the 
designated air mover is not a furnace or modular blower, divide the 
shoulder season total off mode power (P1x) by the number of compressors 
to calculate P1, the shoulder season per-compressor off mode power. 
Round P1 to the nearest watt. The expression for calculating P1 is as 
follows:

[[Page 603]]

    For coil-only split systems and blower coil split systems for which 
a furnace or a modular blower is the designated air mover, subtract the 
low-voltage power (Px) from the shoulder season total off mode power 
(P1x) and divide by the number of compressors to calculate P1, the 
shoulder season per-compressor off mode power. Round P1 to the nearest 
watt. The expression for calculating P1 is as follows:

   3.13.2 This Test Determines the Off Mode Average Power Rating for 
 Central Air Conditioners and Heat Pumps for Which Ambient Temperature 
          Can Affect the Measurement of Crankcase Heater Power

    a. Test Sample Set-up and Power Measurement: set up the test and 
measurement as described in section 3.13.1.a of this appendix.
    b. Configure Controls: Position a temperature sensor to measure the 
outdoor dry-bulb temperature in the air between 2 and 6 inches from the 
crankcase heater control temperature sensor or, if no such temperature 
sensor exists, position it in the air between 2 and 6 inches from the 
crankcase heater. Utilize the temperature measurements from this sensor 
for this portion of the test procedure. Configure the controls of the 
central air conditioner or heat pump so that it operates as if connected 
to a building thermostat that is set to the OFF position. Use a 
compatible building thermostat if necessary to achieve this 
configuration.
    Conduct the test after completion of the B, B1, or 
B2 test. Alternatively, start the test when the outdoor dry-
bulb temperature is at 82 [deg]F and the temperature of the compressor 
shell (or temperature of each compressor's shell if there is more than 
one compressor) is at least 81 [deg]F. Then adjust the outdoor 
temperature and achieve an outdoor dry-bulb temperature of 72 [deg]F. If 
the unit's compressor has no sound blanket, wait at least 4 hours after 
the outdoor temperature reaches 72 [deg]F. Otherwise, wait at least 8 
hours after the outdoor temperature reaches 72 [deg]F. Maintain this 
temperature within 2 [deg]F while the compressor 
temperature equilibrates and while making the power measurement, as 
described in section 3.13.2.c of this appendix.
    c. Measure P1x: If the unit has a crankcase heater time delay, make 
sure that time-delay function is disabled or wait until delay time has 
passed. Determine the average power from non-zero value data measured 
over a 5-minute interval of the non-operating central air conditioner or 
heat pump and designate the average power as P1x, the shoulder season 
total off mode power. For units with crankcase heaters which operate 
during this part of the test and whose controls cycle or vary crankcase 
heater power over time, the test period shall consist of three complete 
crankcase heater cycles or 18 hours, whichever comes first. Designate 
the average power over the test period as P1x, the shoulder season total 
off mode power.
    d. Reduce outdoor temperature: Approach the target outdoor dry-bulb 
temperature by adjusting the outdoor temperature. This target 
temperature is five degrees Fahrenheit less than the temperature 
certified by the manufacturer as the temperature at which the crankcase 
heater turns on. If the unit's compressor has no sound blanket, wait at 
least 4 hours after the outdoor temperature reaches the target 
temperature. Otherwise, wait at least 8 hours after the outdoor 
temperature reaches the target temperature. Maintain the target 
temperature within 2 [deg]F while the compressor 
temperature equilibrates and while making the power measurement, as 
described in section 3.13.2.e of this appendix.
    e. Measure P2x: If the unit has a crankcase heater time delay, make 
sure that time-delay function is disabled or wait until delay time has 
passed. Determine the average non-zero power of the non-operating 
central air conditioner or heat pump over a 5-minute interval and 
designate it as P2x, the heating season total off mode power. For units 
with crankcase heaters whose controls cycle or vary crankcase heater 
power over time, the test period shall consist of three complete 
crankcase heater cycles or 18 hours, whichever comes first. Designate 
the average power over the test period as P2x, the heating season total 
off mode power.
    f. Measure Px for coil-only split systems and for blower coil split 
systems for which a furnace or modular blower is the designated air 
mover: Disconnect all low-voltage wiring for the outdoor components and 
outdoor controls from the low-voltage transformer. Determine the average 
power from non-zero

[[Page 604]]

value data measured over a 5-minute interval of the power supplied to 
the (remaining) low-voltage components of the central air conditioner or 
heat pump, or low-voltage power, Px. This power measurement does not 
include line power supplied to the outdoor unit. It is the line power 
supplied to the air mover, or, if a compatible transformer is 
used instead of an air mover, it is the line power supplied to the 
transformer primary coil. If a compatible transformer is used instead of 
an air mover and power output of the low-voltage secondary circuit is 
measured, Px is zero.
    g. Calculate P1:
    Set the number of compressors equal to the unit's number of single-
stage compressors plus 1.75 times the unit's number of compressors that 
are not single-stage.
    For single-package systems and blower coil split systems for which 
the air mover is not a furnace or modular blower, divide the shoulder 
season total off mode power (P1x) by the number of compressors to 
calculate P1, the shoulder season per-compressor off mode power. Round 
to the nearest watt. The expression for calculating P1 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.201

    For coil-only split systems and blower coil split systems for which 
a furnace or a modular blower is the designated air mover, subtract the 
low-voltage power (Px) from the shoulder season total off mode power 
(P1x) and divide by the number of compressors to calculate P1, the 
shoulder season per-compressor off mode power. Round to the nearest 
watt. The expression for calculating P1 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.202

    h. Calculate P2:
    Determine the number of compressors as described in section 3.13.2.g 
of this appendix.
    For, single-package systems and blower coil split systems for which 
the air mover is not a furnace, divide the heating season total off mode 
power (P2x) by the number of compressors to calculate P2, the heating 
season per-compressor off mode power. Round to the nearest watt. The 
expression for calculating P2 is as follows:
[GRAPHIC] [TIFF OMITTED] TR05JA17.203

    For coil-only split systems and blower coil split systems for which

heating season per-compressor off mode power. Round to the nearest watt.

Tj = the outdoor bin temperature, [deg]F. Outdoor 
          temperatures are grouped or ``binned.'' Use bins of 5 [deg]F 
          with the 8 cooling season bin temperatures being 67, 72, 77, 
          82, 87, 92, 97, and 102 [deg]F.
j = the bin number. For cooling season calculations, j ranges from 1 to 
          8.
    Additionally, for sections 4.1.2, 4.1.3, and 4.1.4 of this appendix, 
use a building cooling load, BL(Tj). When referenced, 
evaluate BL(Tj) for cooling using,

The temperatures 95 [deg]F and 65 [deg]F in the building load equation 
          represent the selected outdoor design temperature and the 
          zero-load base temperature, respectively.
V is a factor equal to 0.93 for variable-speed heat pumps and otherwise 
          equal to 1.0.

                        Conditioner or Heat Pump

    a. Evaluate the seasonal energy efficiency ratio, expressed in units 
of Btu/watt-hour, using:
    SEER2 = PLF(0.5) * EERB
where:

[[Page 606]]

[GRAPHIC] [TIFF OMITTED] TR05JA17.208

PLF(0.5) = 1 - 0.5 [middot] CD\c\, the part-load performance 
          factor evaluated at a cooling load factor of 0.5, 
          dimensionless.
    b. Refer to section 3.3 of this appendix regarding the definition 
and calculation of Qc(82) and Ec(82). Evaluate the 
cooling mode cyclic degradation factor CD\c\ as specified in 
section 3.5.3 of this appendix.

 4.1.2 SEER2 Calculations for an Air Conditioner or Heat Pump Having a 
 Single-Speed Compressor and a Variable-Speed Variable-Air-Volume-Rate 
                              Indoor Blower

 4.1.2.1 Units Covered by Section 3.2.2.1 of This Appendix Where Indoor 
    Blower Capacity Modulation Correlates With the Outdoor Dry Bulb 
                               Temperature

    The manufacturer must provide information on how the indoor air 
volume rate or the indoor blower speed varies over the outdoor 
temperature range of 67 [deg]F to 102 [deg]F. Calculate SEER2 using 
Equation 4.1-1. Evaluate the quantity qc(Tj)/N in 
Equation 4.1-1 using,

Qc(Tj) = the space cooling capacity of the test 
          unit when operating at outdoor temperature, Tj, 
          Btu/h.
nj/N = fractional bin hours for the cooling season; the ratio 
          of the number of hours during the cooling season when the 
          outdoor temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          cooling season, dimensionless.
    a. For the space cooling season, assign nj/N as specified 
in Table 19. Use Equation 4.1-2 to calculate the building load, 
BL(Tj). Evaluate Qc(Tj) using,

          Tj if operated at the cooling minimum air volume 
          rate, Btu/h.

the space cooling capacity of the test unit at outdoor temperature 
          Tj if operated at the Cooling full-load air volume 
          rate, Btu/h.
    b. For units where indoor blower speed is the primary control 
variable, FPck=1 denotes the fan speed used during the 
required A1 and B1 tests (see section 3.2.2.1 of 
this appendix), FPck=2 denotes the fan speed used during the 
required A2 and B2 tests, and 
FPc(Tj) denotes the fan speed used by the unit 
when the outdoor temperature equals Tj. For units where 
indoor air volume rate is the primary control variable, the three 
FPc's are similarly defined only now being expressed in terms 
of air volume rates rather than fan speeds. Refer to sections 3.2.2.1, 
3.1.4 to 3.1.4.2, and 3.3 of this appendix regarding the definitions and 
calculations of Qck=1(82), Qck=1(95),Qc 
k=2(82), and Qck=2(95).
    Calculate ec(Tj)/N in Equation 4.1-1 using, 
Equation 4.1.2-3
[GRAPHIC] [TIFF OMITTED] TR05JA17.214

where:
PLFj = 1 - CD\c\ [middot] [1 - X(Tj)], 
          the part load factor, dimensionless.
Ec(Tj) = the electrical power consumption of the 
          test unit when operating at outdoor temperature Tj, 
          W.
    c. The quantities X(Tj) and nj/N are the same 
quantities as used in Equation 4.1.2-1. Evaluate the cooling mode cyclic 
degradation factor CD\c\ as specified in section 3.5.3 of 
this appendix.
    d. Evaluate Ec(Tj) using,
    [GRAPHIC] [TIFF OMITTED] TR05JA17.215
    

the electrical power consumption of the test unit at outdoor temperature 
Tj if operated at the cooling minimum air volume rate, W.
[GRAPHIC] [TIFF OMITTED] TR05JA17.216


[[Page 608]]


    e. The parameters FPck=1, and FPck=2, and 
FPc(Tj) are the same quantities that are used when 
evaluating Equation 4.1.2-2. Refer to sections 3.2.2.1, 3.1.4 to 
3.1.4.2, and 3.3 of this appendix regarding the definitions and 
calculations of Eck=1(82), Eck=1(95), 
Eck=2(82), and Eck=2(95).

 4.1.2.2 Units Covered by Section 3.2.2.2 of This Appendix Where Indoor 
   Blower Capacity Modulation is Used to Adjust the Sensible to Total 
                         Cooling Capacity Ratio

    Calculate SEER2 as specified in section 4.1.1 of this appendix.

 4.1.3 SEER2 Calculations for an Air Conditioner or Heat Pump Having a 
                         Two-Capacity Compressor

    Calculate SEER2 using Equation 4.1-1. Evaluate the space cooling 
capacity, Qck=1 (Tj), and electrical power 
consumption, Eck=1 (Tj), of the test unit when 
operating at low compressor capacity and outdoor temperature 
Tj using,
[GRAPHIC] [TIFF OMITTED] TR05JA17.217

[GRAPHIC] [TIFF OMITTED] TR05JA17.218

where Qck=1 (82) and Eck=1 (82) are determined 
from the B1 test, Qck=1 (67) and Eck=1 
(67) are determined from the F1 test, and all four quantities 
are calculated as specified in section 3.3 of this appendix. Evaluate 
the space cooling capacity, Qck=2 (Tj), and 
electrical power consumption, Eck=2 (Tj), of the 
test unit when operating at high compressor capacity and outdoor 
temperature Tj using,
[GRAPHIC] [TIFF OMITTED] TR05JA17.219

[GRAPHIC] [TIFF OMITTED] TR05JA17.220

where Qck=2(95) and Eck=2(95) are determined from 
the A2 test, Qck=2(82), and Eck=2(82), 
are determined from the B2 test, and all are calculated as 
specified in section 3.3 of this appendix.
    The calculation of Equation 4.1-1 quantities 
qc(Tj)/N and ec(Tj)/N 
differs depending on whether the test unit would operate at low capacity 
(section 4.1.3.1 of this appendix), cycle between low and high capacity 
(section 4.1.3.2 of this appendix), or operate at high capacity 
(sections 4.1.3.3 and 4.1.3.4 of this appendix) in responding to the 
building load. For units that lock out low capacity operation at higher 
outdoor temperatures, the outdoor temperature at which the unit locks 
out must be that specified by the manufacturer in the certification 
report so that the appropriate equations are used. Use Equation 4.1-2 to 
calculate the building load, BL(Tj), for each temperature 
bin.

    nj/N = fractional bin hours for the cooling season; the 
ratio of the number of hours during the cooling season when the outdoor 
temperature fell within the range represented by bin temperature 
Tj to the total number of hours in the cooling season, 
dimensionless.
    Obtain the fractional bin hours for the cooling season, 
nj/N, from Table 19. Use Equations 4.1.3-1 and 4.1.3-2, 
respectively, to evaluate Qck=1(Tj) and 
Eck=1(Tj). Evaluate the cooling mode cyclic 
degradation factor CD\c\ as specified in section 3.5.3 of 
this appendix.

     4.2 Heating Seasonal Performance Factor 2 (HSPF2) Calculations

    Unless an approved alternative efficiency determination method is 
used, as set forth in 10 CFR 429.70(e). Calculate HSPF2 as follows: Six 
generalized climatic regions are depicted in Figure 1 and otherwise 
defined in Table 20. For each of these regions and for each applicable 
standardized design heating requirement, evaluate the heating seasonal 
performance factor using,
[GRAPHIC] [TIFF OMITTED] TR05JA17.238

Where:

eh(Tj)/N = The ratio of the electrical energy consumed by the 
          heat pump during periods of the heating season when the 
          outdoor temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          heating season (N), W. For heat pumps having a heat comfort 
          controller, this ratio may also include electrical energy used 
          by resistive elements to maintain a minimum air delivery 
          temperature (see 4.2.5).
RH(Tj)/N = The ratio of the electrical energy used for 
          resistive space heating during periods when the outdoor 
          temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          heating season (N), W. Except as noted in section 4.2.5 of 
          this appendix, resistive space heating is modeled as being 
          used to meet that portion of the building load that the heat 
          pump does not meet because of insufficient capacity or because 
          the heat pump automatically turns off at the lowest outdoor 
          temperatures. For heat pumps having a heat comfort controller, 
          all or part of the electrical energy used by resistive heaters 
          at a particular bin temperature may be reflected in 
          eh(Tj)/N (see section 4.2.5 of this appendix).
Tj = the outdoor bin temperature, [deg]F. Outdoor 
          temperatures are ``binned'' such that calculations are only 
          performed based one temperature within the bin. Bins of 5 
          [deg]F are used.
nj/N = Fractional bin hours for the heating season; the ratio 
          of the number of hours during the heating season when the 
          outdoor temperature fell within the range represented by bin 
          temperature Tj to the total number of hours in the 
          heating season, dimensionless. Obtain nj/N values 
          from Table 20.
j = the bin number, dimensionless.
J = for each generalized climatic region, the total number of 
          temperature bins, dimensionless. Referring to Table 20, J is 
          the highest bin number (j) having a nonzero entry for the 
          fractional bin hours for the generalized climatic region of 
          interest.
Fdef = the demand defrost credit described in section 3.9.2 
          of this appendix, dimensionless.
BL(Tj) = the building space conditioning load corresponding 
          to an outdoor temperature of Tj; the heating season 
          building load also depends on the generalized climatic 
          region's outdoor design temperature and the design heating 
          requirement, Btu/h.

    a. For all heat pumps, HSPF2 accounts for the heating delivered and 
the energy consumed by auxiliary resistive elements when operating below 
the balance point. This condition occurs when the building load exceeds 
the space heating capacity of the heat pump condenser. For HSPF2 
calculations for all heat pumps, see either section 4.2.1, 4.2.2, 4.2.3,

this appendix, Definitions), HSPF2 also accounts for resistive heating 
contributed when operating above the heat-pump-plus-comfort-controller 
balance point as a result of maintaining a minimum supply temperature. 
For heat pumps having a heat comfort controller, see section 4.2.5 of

    The calculation of the Equation 4.2-1 quantities differ depending 
upon whether the heat pump would operate at low capacity (section

heat pumps that lock out low capacity operation at low outdoor 
temperatures, the outdoor temperature at which the unit locks out must 
be that specified by the manufacturer in the certification report so 
that the appropriate equations can be selected.

            4.2.5 Heat Pumps Having a Heat Comfort Controller

    Heat pumps having heat comfort controllers, when set to maintain a 
typical minimum air delivery temperature, will cause the heat pump 
condenser to operate less because of a greater contribution from the 
resistive elements. With a conventional heat pump, resistive heating is 
only initiated if the heat pump condenser cannot meet the building load 
(i.e., is delayed until a second stage call from the indoor thermostat). 
With a heat comfort controller, resistive heating can occur even though 
the heat pump condenser has adequate capacity to meet the building load 
(i.e., both on during a first stage call from the indoor thermostat). As 
a result, the outdoor temperature where the heat pump compressor no 
longer cycles (i.e., starts to run continuously), will be lower than if 
the heat pump did not have the heat comfort controller.

capacity (section 4.2.6.1 of this appendix), cycle on and off at high 
capacity (section 4.2.6.2 of this appendix), cycle on and off at booster 
capacity (section 4.2.6.3 of this appendix), cycle between low and high 
capacity (section 4.2.6.4 of this appendix), cycle between high and 
booster capacity (section 4.2.6.5 of this appendix), operate 
continuously at low capacity (section 4.2.6.6 of this appendix), operate 
continuously at high capacity (section 4.2.6.7 of this appendix), 
operate continuously at booster capacity (section 4.2.6.8 of this 
appendix), or heat solely using resistive heating (also section 4.2.6.8 
of this appendix) in responding to the building load. As applicable, the 
manufacturer must supply information regarding the outdoor temperature 
range at which each stage of compressor capacity is active. As an 
informative example, data may be submitted in this manner: At the low

40 [deg]F <= T <= 65 [deg]F; At the high (k=2) compressor capacity, the 
outdoor temperature range of operation is 20 [deg]F <= T <= 50 [deg]F;

controls, sufficient fluid source(s), applicable measurement equipment, 
and any other technology or tools) necessary for performance of the test 
and must be able to maintain conditions within the limits specified in 
section 6 of this appendix.
    6.2 Forced-air central furnaces (direct vent and direct exhaust).
    a. Units not equipped with a draft hood or draft diverter must be 
provided with the minimum-length vent configuration recommended in the 
I&O manual or a 5-ft flue pipe if there is no recommendation provided in 
the I&O manual (see Figure 4 of ASHRAE 103-1993 (incorporated by 
reference, see Sec. 430.3)). For a direct exhaust system, insulate the 
minimum-length vent configuration or the 5-ft flue pipe with insulation 
having an R-value not less than 7 and an outer layer of aluminum foil. 
For a direct vent system, see section 7.5 of ASHRAE 103-1993 for 
insulation requirements.
    b. For units with power burners, cover the flue collection box with 
insulation having an R-value of not less than 7 and an outer layer of 
aluminum foil before the cool-down and heat-up tests described in 
sections 9.5 and 9.6 of ASHRAE 103-1993 (incorporated by reference, see 
Sec. 430.3), respectively. However, do not apply the insulation for the 
jacket loss test (if conducted) described in section 8.6 of ASHRAE 103-
1993 or the steady-state test described in section 9.1 of ASHRAE 103-
1993.
    c. For power-vented units, insulate the shroud surrounding the 
blower impeller with insulation having an R-value of not less than 7 and 
an outer layer of aluminum foil before the cool-down and heat-up tests 
described in sections 9.5 and 9.6, respectively, of ASHRAE 103-1993 
(incorporated by reference, see Sec. 430.3). Do not apply the 
insulation for the jacket loss test (if conducted) described in section 
8.6 of ASHRAE 103-1993 or the steady-state test described in section 9.1 
of ASHRAE 103-1993. Do not insulate the blower motor or block the 
airflow openings that facilitate the cooling of the combustion blower 
motor or bearings.
    6.3 Downflow furnaces. Install an internal section of vent pipe the 
same size as the flue collar for connecting the flue collar to the top 
of the unit, if not supplied by the manufacturer. Do not insulate the 
internal vent pipe during the jacket loss test (if conducted) described 
in section 8.6 of ASHRAE 103-1993 (incorporated by reference, see Sec. 
430.3) or the steady-state test described in section 9.1 of ASHRAE 103-
1993. Do not insulate the internal vent pipe before the cool-down and 
heat-up tests described in sections 9.5 and 9.6, respectively, of ASHRAE 
103-1993. If the vent pipe is surrounded by a metal jacket, do not 
insulate the metal jacket. Install a 5-ft test stack of the same cross-
sectional area or perimeter as the vent pipe above the top of the 
furnace. Tape or seal around the junction connecting the vent pipe and 
the 5-ft test stack. Insulate the 5-ft test stack with insulation having 
an R-value not less than 7 and an outer layer of aluminum foil. (See 
Figure 3-E of ASHRAE 103-1993.)
    6.4 Units with draft hoods or draft diverters. Install the stack 
damper in accordance with the I&O manual. Install 5 feet of stack above 
the damper.
    a. For units with an integral draft diverter, cover the 5-ft stack 
with insulation having an R-value of not less than 7 and an outer layer 
of aluminum foil.
    b. For units with draft hoods, insulate the flue pipe between the 
outlet of the furnace and the draft hood with insulation having an R-
value of not less than 7 and an outer layer of aluminum foil.
    c. For units with integral draft diverters that are mounted in an 
exposed position (not

[[Page 637]]

inside the overall unit cabinet), cover the diverter boxes (excluding 
any openings through which draft relief air flows) before the beginning 
of any test (including jacket loss test) with insulation having an R-
value of not less than 7 and an outer layer of aluminum foil.
    d. For units equipped with integral draft diverters that are 
enclosed within the overall unit cabinet, insulate the draft diverter 
box with insulation as described in section 6.4.c before the cool-down 
and heat-up tests described in sections 9.5 and 9.6, respectively, of 
ASHRAE 103-1993 (incorporated by reference, see Sec. 430.3). Do not 
apply the insulation for the jacket loss test (if conducted) described 
in section 8.6 of ASHRAE 103-1993 or the steady-state test described in 
section 9.1 of ASHRAE 103-1993.
    6.5 Condensate collection. Attach condensate drain lines to the unit 
as specified in the I&O manual. Maintain a continuous downward slope of 
drain lines from the unit. Additional precautions (such as eliminating 
any line configuration or position that would otherwise restrict or 
block the flow of condensate or checking to ensure a proper connection 
with condensate drain spout that allows for unobstructed flow) must be 
taken to facilitate uninterrupted flow of condensate during the test. 
Collection containers must be glass or polished stainless steel to 
facilitate removal of interior deposits. The collection container must 
have a vent opening to the atmosphere.
    7.0 Testing conditions. The testing conditions must be as specified 
in section 8 of ASHRAE 103-1993 (incorporated by reference, see Sec. 
430.3), except for section 8.2.1.3, 8.3.3.1, 8.4.1.1, 8.4.1.1.2, 
8.4.1.2, 8.4.2.1.4, 8.4.2.1.6, 8.6.1.1, 8.7.2, and 8.8.3; and as 
specified in sections 7.1 to 7.10 of this appendix, respectively.
    7.1 Fuel supply, gas. In conducting the tests specified herein, 
gases with characteristics as shown in Table 1 of ASHRAE 103-1993 
(incorporated by reference, see Sec. 430.3) shall be used. Maintain the 
gas supply, ahead of all controls for a furnace, at a test pressure 
between the normal and increased values shown in Table 1 of ASHRAE 103-
1993. Maintain the regulator outlet pressure at a level approximating 
that recommended in the I&O manual, as defined in section 2.6 of this 
appendix, or, in the absence of such recommendation, to the nominal 
regulator settings used when the product is shipped by the manufacturer. 
Use a gas having a specific gravity as shown in Table 1 of ASHRAE 103-
1993 and with a higher heating value within 5% of 
the higher heating value shown in Table 1 of ASHRAE 103-1993. Determine 
the actual higher heating value in Btu per standard cubic foot for the 
gas to be used in the test within an error no greater than 1%.
    7.2 Installation of piping. Install piping equipment in accordance 
with the I&O manual. In the absence of such specification, install 
piping in accordance with section 8.3.1.1 of ASHRAE 103-1993 
(incorporated by reference, see Sec. 430.3).
    7.3 Gas burner. Adjust the burners of gas-fired furnaces and boilers 
to their maximum Btu input ratings at the normal test pressure specified 
by section 7.1 of this appendix. Correct the burner input rate to 
reflect gas characteristics at a temperature of 60 [deg]F and 
atmospheric pressure of 30 in of Hg and adjust down to within 2 percent of the hourly Btu nameplate input rating 
specified by the manufacturer as measured during the steady-state 
performance test in section 8 of this appendix. Set the primary air 
shutters in accordance with the I&O manual to give a good flame at this 
condition. If, however, the setting results in the deposit of carbon on 
the burners during any test specified herein, the tester shall adjust 
the shutters and burners until no more carbon is deposited and shall 
perform the tests again with the new settings (see Figure 9 of ASHRAE 
103-1993 (incorporated by reference, see Sec. 430.3)). After the 
steady-state performance test has been started, do not make additional 
adjustments to the burners during the required series of performance 
tests specified in section 9 of ASHRAE 103-1993. If a vent-limiting 
means is provided on a gas pressure regulator, keep it in place during 
all tests.
    7.4 Modulating gas burner adjustment at reduced input rate. For gas-
fired furnaces and boilers equipped with modulating-type controls, 
adjust the controls to operate the unit at the nameplate minimum input 
rate. If the modulating control is of a non-automatic type, adjust the 
control to the setting recommended in the I&O manual. In the absence of 
such recommendation, the midpoint setting of the non-automatic control 
shall be used as the setting for determining the reduced fuel input 
rate. Start the furnace or boiler by turning the safety control valve to 
the ``ON'' position. For boilers, use a supply water temperature that 
will allow for continuous operation without shutoff by the control. If 
necessary to achieve such continuous operation, supply water may be 
increased above 120 [deg]F; in such cases, gradually increase the supply 
water temperature to determine what minimum supply water temperature, 
with a 20 [deg]F temperature rise across the boiler, will be needed to 
adjust for the minimum input rate at the reduced input rate control 
setting. Monitor regulated gas pressure out of the modulating control 
valve (or entering the burner) to determine when no further reduction of 
gas pressure results. The flow rate of water through the boiler shall be 
adjusted to achieve a 20 [deg]F temperature rise.

[[Page 638]]

    7.5 Oil burner. Adjust the burners of oil-fired furnaces or boilers 
to give a CO2 reading specified in the I&O manual and an 
hourly Btu input during the steady-state performance test described in 
section 8 of this appendix. Ensure the hourly BTU input is within 2% of the normal hourly Btu input rating as specified in 
the I&O manual. Smoke in the flue may not exceed a No. 1 smoke during 
the steady-state performance test as measured by the procedure in ASTM 
D2156R13 (incorporated by reference, see Sec. 430.3). Maintain the 
average draft over the fire and in the flue during the steady-state 
performance test at the value specified in the I&O manual. Do not allow 
draft fluctuations exceeding 0.005 in. water. Do not make additional 
adjustments to the burner during the required series of performance 
tests. The instruments and measuring apparatus for this test are 
described in section 6 of this appendix and shown in Figure 8 of ASHRAE 
103-1993 (incorporated by reference, see Sec. 430.3).
    7.6 Adjust air throughputs to achieve a temperature rise that is the 
higher of a and b, below, unless c applies. A tolerance of 2 [deg]F is permitted.
    a. 15 [deg]F less than the nameplate maximum temperature rise or
    b. 15 [deg]F higher than the minimum temperature rise specified in 
the I&O manual.
    c. A furnace with a non-adjustable air temperature rise range and an 
automatically controlled airflow that does not permit a temperature rise 
range of 30 [deg]F or more must be tested at the midpoint of the rise 
range.
    7.7 Establish the temperature rise specified in section 7.6 of this 
appendix by adjusting the circulating airflow. This adjustment must be 
accomplished by symmetrically restricting the outlet air duct and 
varying blower speed selection to obtain the desired temperature rise 
and minimum external static pressure, as specified in Table 4 of ASHRAE 
103-1993 (incorporated by reference, see Sec. 430.3). If the required 
temperature rise cannot be obtained at the minimum specified external 
static pressure by adjusting blower speed selection and duct outlet 
restriction, then the following applies.
    a. If the resultant temperature rise is less than the required 
temperature rise, vary the blower speed by gradually adjusting the 
blower voltage so as to maintain the minimum external static pressure 
listed in Table 4 of ASHRAE 103-1993 (incorporated by reference, see 
Sec. 430.3). The airflow restrictions shall then remain unchanged. If 
static pressure must be varied to prevent unstable blower operation, 
then increase the static pressure until blower operation is stabilized, 
except that the static pressure must not exceed the maximum external 
static pressure as specified by the manufacturer in the I&O manual.
    b. If the resultant temperature rise is greater than the required 
temperature rise, then the unit can be tested at a higher temperature 
rise value, but one not greater than nameplate maximum temperature rise. 
In order not to exceed the maximum temperature rise, the speed of a 
direct-driven blower may be increased by increasing the circulating air 
blower motor voltage.
    7.8 Measurement of jacket surface temperature. Divide the jacket of 
the furnace or boiler into 6-inch squares when practical, and otherwise 
into 36-square-inch regions comprising 4 inch by 9 inch or 3 inch by 12 
inch sections, and determine the surface temperature at the center of 
each square or section with a surface thermocouple. Record the surface 
temperature of the 36-square-inch areas in groups where the temperature 
differential of the 36-square-inch areas is less than 10 [deg]F for 
temperature up to 100 [deg]F above room temperature, and less than 20 
[deg]F for temperatures more than 100 [deg]F above room temperature. For 
forced-air central furnaces, the circulating air blower compartment is 
considered as part of the duct system, and no surface temperature 
measurement of the blower compartment needs to be recorded for the 
purpose of this test. For downflow furnaces, measure all cabinet surface 
temperatures of the heat exchanger and combustion section, including the 
bottom around the outlet duct and the burner door, using the 36-square-
inch thermocouple grid. The cabinet surface temperatures around the 
blower section do not need to be measured (See Figure 3-E of ASHRAE 103-
1993 (incorporated by reference, see Sec. 430.3)).
    7.9 Installation of vent system. Keep the vent or air intake system 
supplied by the manufacturer in place during all tests. Test units 
intended for installation with a variety of vent pipe lengths with the 
minimum vent length as specified in the I&O manual, or a 5-ft. flue pipe 
if there are no recommendations in the I&O manual. Do not connect a 
furnace or boiler employing a direct vent system to a chimney or 
induced-draft source. Vent combustion products solely by using the 
venting incorporated in the furnace or boiler and the vent or air intake 
system supplied by the manufacturer. For units that are not designed to 
significantly preheat the incoming air, see section 7.5 of this appendix 
and Figure 4a or 4b of ASHRAE 103-1993 (incorporated by reference, see 
Sec. 430.3). For units that do significantly preheat the incoming air, 
see Figure 4c or 4d of ASHRAE 103-1993.
    7.10 Additional optional method of testing for determining DP and DF 
for furnaces and boilers. On units whose design is such that there is no 
measurable airflow through the combustion chamber and heat exchanger 
when the burner(s) is (are) off as determined by the optional test 
procedure in section 7.10.1 of this appendix, DF and 
DP may be set equal to 0.05.

[[Page 639]]

    7.10.1 Optional test method for indicating the absence of flow 
through the heat exchanger. Manufacturers may use the following test 
protocol to determine whether air flows through the combustion chamber 
and heat exchanger when the burner(s) is (are) off. The minimum default 
draft factor (as allowed per sections 8.8.3 and 9.10 of ASHRAE 103-1993 
(incorporated by reference, see Sec. 430.3)) may be used only for units 
determined pursuant to this protocol to have no airflow through the 
combustion chamber and heat exchanger.
    7.10.1.1 Test apparatus. Use a smoke stick that produces smoke that 
is easily visible and has a density less than or approximately equal to 
air. Use a smoke stick that produces smoke that is non-toxic to the test 
personnel and produces gas that is unreactive with the environment in 
the test chamber.
    7.10.1.2 Test conditions. Minimize all air currents and drafts in 
the test chamber, including turning off ventilation if the test chamber 
is mechanically ventilated. Wait at least two minutes following the 
termination of the furnace or boiler on-cycle before beginning the 
optional test method for indicating the absence of flow through the heat 
exchanger.
    7.10.1.3 Location of the test apparatus. After all air currents and 
drafts in the test chamber have been eliminated or minimized, position 
the smoke stick based on the following equipment configuration: (a) For 
horizontal combustion air intakes, approximately 4 inches from the 
vertical plane at the termination of the intake vent and 4 inches below 
the bottom edge of the combustion air intake; or (b) for vertical 
combustion air intakes, approximately 4 inches horizontal from vent 
perimeter at the termination of the intake vent and 4 inches down 
(parallel to the vertical axis of the vent). In the instance where the 
boiler combustion air intake is closer than 4 inches to the floor, place 
the smoke device directly on the floor without impeding the flow of 
smoke.
    7.10.1.4 Duration of test. Establish the presence of smoke from the 
smoke stick and then monitor the direction of the smoke flow for no less 
than 30 seconds.
    7.10.1.5 Test results. During visual assessment, determine whether 
there is any draw of smoke into the combustion air intake vent.
    If absolutely no smoke is drawn into the combustion air intake, the 
furnace or boiler meets the requirements to allow use of the minimum 
default draft factor pursuant to section 8.8.3 and/or section 9.10 of 
ASHRAE 103-1993 (incorporated by reference, see Sec. 430.3).
    If there is any smoke drawn into the intake, proceed with the 
methods of testing as prescribed in section 8.8 of ASHRAE 103-1993.
    8.0 Test procedure. Conduct testing and measurements as specified in 
section 9 of ASHRAE 103-1993 (incorporated by reference, see Sec. 
430.3) except for sections 9.1.2.2.1, 9.1.2.2.2, 9.5.1.1, 9.5.1.2.1, 
9.5.1.2.2, 9.5.2.1, 9.7.4, and 9.10; and as specified in sections 8.1 
through 8.11 of this appendix. Section 8.4 of this appendix may be used 
in lieu of section 9.2 of ASHRAE 103-1993.
    8.1 Fuel input. For gas units, measure and record the steady-state 
gas input rate in Btu/hr, including pilot gas, corrected to standard 
conditions of 60 [deg]F and 30 in. Hg. Use measured values of gas 
temperature and pressure at the meter and barometric pressure to correct 
the metered gas flow rate to the above standard conditions. For oil 
units, measure and record the steady-state fuel input rate.
    8.2 Electrical input. For furnaces and boilers, during the steady-
state test, perform a single measurement of all of the electrical power 
involved in burner operation (PE), including energizing the ignition 
system, controls, gas valve or oil control valve, and draft inducer, if 
applicable. For boilers, the measurement of PE must include the boiler 
pump if so equipped. If the boiler pump does not operate during the 
measurement of PE, add the boiler pump nameplate power to the 
measurement of PE. If the boiler pump nameplate power is not available, 
use 0.13 kW.
    For furnaces, during the steady-state test, perform a single 
measurement of the electrical power to the circulating air blower (BE). 
For hot water boilers, use the circulating water pump nameplate power 
for BE, or if the pump nameplate power is not available, use 0.13 kW.
    8.3 Input to interrupted ignition device. For burners equipped with 
an interrupted ignition device, record the nameplate electric power used 
by the ignition device, PEIG, or record that PEIG 
= 0.4 kW if no nameplate power input is provided. Record the nameplate 
ignition device on-time interval, tIG, or, if the nameplate 
does not provide the ignition device on-time interval, measure the on-
time interval with a stopwatch at the beginning of the test, starting 
when the burner is turned on. Set tIG = 0 and PEIG 
= 0 if the device on-time interval is less than or equal to 5 seconds 
after the burner is on.
    8.4 Optional test procedures for condensing furnaces and boilers, 
measurement of condensate during the establishment of steady-state 
conditions. For units with step-modulating or two-stage controls, 
conduct the test at both the maximum and reduced inputs. In lieu of 
collecting the condensate immediately after the steady state conditions 
have been reached as required by section 9.2 of ASHRAE 103-1993 
(incorporated by reference, see Sec. 430.3), condensate may be 
collected during the establishment of steady state conditions as defined 
by section 9.1.2.1 of ASHRAE 103-1993. Perform condensate collection for 
at least 30 minutes. Measure condensate

[[Page 640]]

mass immediately at the end of the collection period to prevent 
evaporation loss from the sample. Record fuel input for the 30-minute 
condensate collection test period. Observe and record fuel higher 
heating value (HHV), temperature, and pressures necessary for 
determining fuel energy input (Qc,ss). Measure the fuel quantity and HHV 
with errors no greater than 1%. The humidity for the room air shall at 
no time exceed 80%. Determine the mass of condensate for the 
establishment of steady state conditions (Mc,ss) in pounds by 
subtracting the tare container weight from the total container and 
condensate weight measured at the end of the 30-minute condensate 
collection test period.
    8.5 Cool-down test for gas- and oil-fueled gravity and forced-air 
central furnaces without stack dampers. Turn off the main burner after 
completing steady-state testing, and measure the flue gas temperature by 
means of the thermocouple grid described in section 7.6 of ASHRAE 103-
1993 (incorporated by reference, see Sec. 430.3) at 1.5 minutes 
(TF,OFF(t3)) and 9 minutes 
(TF,OFF(t4)) after shutting off the burner. When 
taking these temperature readings, the integral draft diverter must 
remain blocked and insulated, and the stack restriction must remain in 
place. On atmospheric systems with an integral draft diverter or draft 
hood and equipped with either an electromechanical inlet damper or an 
electromechanical flue damper that closes within 10 seconds after the 
burner shuts off to restrict the flow through the heat exchanger in the 
off-cycle, bypass or adjust the control for the electromechanical damper 
so that the damper remains open during the cool-down test.
    For furnaces that employ post-purge, measure the length of the post-
purge period with a stopwatch. Record the time from burner ``OFF'' to 
combustion blower ``OFF'' (electrically de-energized) as tP. 
If the measured tP is less than or equal to 30 seconds, set 
tP at 0 and conduct the cool-down test as if there is no 
post-purge. If tP is prescribed by the I&O manual or measured 
to be greater than 180 seconds, stop the combustion blower at 180 
seconds and use that value for tP. Measure the flue gas 
temperature by means of the thermocouple grid described in section 7.6 
of ASHRAE 103-1993 at the end of the post-purge period, 
tP(TF,OFF (tP)), and at the time (1.5 + 
tP) minutes (TF,OFF(t3)) and (9.0 + 
tP) minutes (TF,OFF(t4)) after the main 
burner shuts off.
    8.6 Cool-down test for gas- and oil-fueled gravity and forced-air 
central furnaces without stack dampers and with adjustable fan control. 
For a furnace with adjustable fan control, measure the time delay 
between burner shutdown and blower shutdown, t\+\. This time delay, 
t\+\, will be 3.0 minutes for non-condensing furnaces or 1.5 minutes for 
condensing furnaces or until the supply air temperature drops to a value 
of 40 [deg]F above the inlet air temperature, whichever results in the 
longest fan on-time. For a furnace without adjustable fan control or 
with the type of adjustable fan control whose range of adjustment does 
not allow for the time delay, t\+\, specified above, bypass the fan 
control and manually control the fan to allow for the appropriate delay 
time as specified in section 9.5.1.2 of ASHRAE 103-1993 (incorporated by 
reference, see Sec. 430.3). For a furnace that employs a single motor 
to drive both the power burner and the indoor air circulating blower, 
the power burner and indoor air circulating blower must be stopped at 
the same time
    8.7 Cool-down test for gas- and oil-fueled boilers without stack 
dampers. After steady-state testing has been completed, turn the main 
burner(s) ``OFF'' and measure the flue gas temperature at 3.75 minutes 
(temperature designated as TF,OFF(t3)) and 22.5 
minutes (temperature designated as TF,OFF(t4)) 
after the burner shut-off using the thermocouple grid described in 
section 7.6 of ASHRAE 103-1993 (incorporated by reference, see Sec. 
430.3).
    a. During this off-period, for units that do not have pump delay 
after shut-off, do not allow any water to circulate through the hot 
water boilers.
    b. For units that have pump delay on shut-off, except those having 
pump controls sensing water temperature, the unit control must stop the 
pump. Measure and record the time between burner shut-off and pump shut-
off (t\+\) to the nearest second.
    c. For units having pump delay controls that sense water 
temperature, operate the pump for 15 minutes and record t\+\ as 15 
minutes. While the pump is operating, maintain the inlet water 
temperature and flow rate at the same values as used during the steady-
state test, as specified in sections 9.1 and 8.4.2.3 of ASHRAE 103-1993 
(incorporated by reference, see Sec. 430.3).
    d. For boilers that employ post-purge, measure the length of the 
post-purge period with a stopwatch. Record the time from burner ``OFF'' 
to combustion blower ``OFF'' (electrically de-energized) as 
tP. If tP is prescribed by the I&O manual or 
measured to be greater than 180 seconds, stop the combustion blower at 
180 seconds and use that value for tP. Measure the flue gas 
temperature by means of the thermocouple grid described in section 7.6 
of ASHRAE 103-1993 at the end of the post-purge period tP 
(TF,OFF(tP)) and at (3.75 + tP) minutes 
(TF,OFF(t3)) and (22.5 + tP) minutes 
(TF,OFF(t4)) after the main burner shuts off. If 
the measured tP is less than or equal to 30 seconds, record 
tP as 0 and conduct the cool-down test as if there is no 
post-purge.
    8.8 Direct measurement of off-cycle losses testing method. 
[Reserved.]
    8.9 Calculation options. The rate of the flue gas mass flow through 
the furnace and the

[[Page 641]]

factors DP, DF, and DS are calculated 
by the equations in sections 11.6.1, 11.6.2, 11.6.3, 11.6.4, 11.7.1, and 
11.7.2 of ASHRAE 103-1993 (incorporated by reference, see Sec. 430.3). 
On units whose design is such that there is no measurable airflow 
through the combustion chamber and heat exchanger when the burner(s) is 
(are) off (as determined by the optional test procedure in section 7.10 
of this appendix), DF and DP may be set equal to 
0.05.
    8.10 Optional test procedures for condensing furnaces and boilers 
that have no off-period flue losses. For units that have applied the 
test method in section 7.10 of this appendix to determine that no 
measurable airflow exists through the combustion chamber and heat 
exchanger during the burner off-period and having post-purge periods of 
less than 5 seconds, the cool-down and heat-up tests specified in 
sections 9.5 and 9.6 of ASHRAE 103-1993 (incorporated by reference, see 
Sec. 430.3) may be omitted. In lieu of conducting the cool-down and 
heat-up tests, the tester may use the losses determined during the 
steady-state test described in section 9.1 of ASHRAE 103-1993 when 
calculating heating seasonal efficiency, EffyHS.
    8.11 Measurement of electrical standby and off mode power.
    8.11.1 Standby power measurement. With all electrical auxiliaries of 
the furnace or boiler not activated, measure the standby power 
(PW,SB) in accordance with the procedures in IEC 62301

corresponding provisions of IEC 62301 at section 4.2, Test room, and the 
voltage specification of section 4.3, Power supply. Frequency shall be 
60Hz. Clarifying further, IEC 62301 section 4.4, Power measurement 
instruments, and section 5, Measurements, apply in lieu of ASHRAE 103-
1993 section 6.10, Energy Flow Rate. Measure the wattage so that all 
possible standby mode wattage for the entire appliance is recorded, not 
just the standby mode wattage of a single auxiliary. Round the recorded 
standby power (PW,SB) to the second decimal place, except for 
loads greater than or equal to 10W, which must be recorded to at least 
three significant figures.
    8.11.2 Off mode power measurement. If the unit is equipped with an 
off switch or there is an expected difference between off mode power and 
standby mode power, measure off mode power

this measurement in lieu of ASHRAE 103-1993 section 6.10, Energy Flow 
Rate. Measure the wattage so that all possible off mode wattage for the 
entire appliance is recorded, not just the off mode wattage of a single 
auxiliary. If there is no expected difference in off mode power and 
standby mode power, let PW,OFF = PW,SB, in which 
case no separate measurement of off mode power is necessary. Round the 
recorded off mode power (PW,OFF) to the second decimal place, 
except for loads greater than or equal to 10W, in which case round the 
recorded value to at least three significant figures.

five (5) foot long vertical test stack. A horizontal section of pipe may 
be used on the floor furnace between the diverter and the elbow if 
necessary to clear any framing used in the installation. Use the minimum 
length of pipe possible for this section. Use stack, elbow, and 
horizontal section with same cross sectional area as the diverter

vented heaters to their maximum Btu ratings at the test pressure 
specified in section 2.3 of this appendix. Correct the burner volumetric 
flow rate to 60 [deg]F (15.6C) and 30 inches of mercury barometric 
pressure, set the fuel flow rate to obtain a heat rate of within 2 percent of the hourly Btu rating specified by the 
manufacturer as measured after 15 minutes of operation starting with all 
parts of the vented heater at room temperature. Set the primary air 
shutters in accordance with the manufacturer's recommendations to give a 
good flame at this adjustment. Do not allow the deposit of carbon during 
any test specified herein.
    If a vent limiting means is provided on a gas pressure regulator, 
have it in place during all tests.
    For gas fueled heaters with modulating controls adjust the controls 
to operate the heater at the maximum fuel input rate. Set the thermostat 
control to the maximum setting. Start the heater by turning the safety 
control valve to the ``on'' position. In order to prevent modulation of 
the burner at maximum input, place the thermostat sensing element in a 
temperature control bath which is held at a temperature below the 
maximum set point temperature of the control.
    For gas fueled heaters with modulating controls adjust the controls 
to operate the heater at the reduced fuel input rate. Set the thermostat 
control to the minimum setting. Start the heater by turning the safety 
control valve to the ``on'' position. If ambient test room temperature 
is above the lowest control set point temperature, initiate burner 
operation by placing the thermostat sensing element in a temperature 
control bath that is held at a temperature below the minimum set point 
temperature of the control.
    2.4.2 Oil burner adjustments. Adjust the burners of oil fueled 
vented heaters to give the CO2 reading recommended by the 
manufacturer and an hourly Btu input, during the steady-state 
performance test described below, which is within 2 percent of the heater manufacturer's specified normal 
hourly Btu input rating. On units employing a power burner, do not allow 
smoke in the flue to exceed a No. 1 smoke during the steady-state 
performance test as measured by the procedure in ASTM D2156 
(incorporated by reference, see Sec. 430.3). If, on units employing a 
power burner, the smoke in the flue exceeds a No. 1 smoke during the 
steady-state test, readjust the burner to give a lower

[[Page 652]]

smoke reading, and, if necessary a lower CO2 reading, and 
start all tests over. Maintain the average draft over the fire and in 
the flue during the steady-state performance test at that recommended by 
the manufacturer within 0.005 inches of water 
gauge. Do not make additional adjustments to the burner during the 
required series of performance tests. The instruments and measuring 
apparatus for this test are described in section 6 and shown in Figure 8 
of ASHRAE 103-2007 (incorporated by reference, see Sec. 430.3).
    2.5 Circulating air adjustments.
    2.5.1 Forced air vented wall furnaces (including direct vent 
systems). During testing, maintain the air flow through the heater as 
specified by the manufacturer in the I&O manual provided with the unit 
and operate the vented heater with the outlet air temperature between 80 
[deg]F and 130 [deg]F above room temperature. If adjustable air 
discharge registers are provided, adjust them so as to provide the 
maximum possible air restriction. Measure air discharge temperature as 
specified in section 8.7 of ANSI Z21.86 (incorporated by reference, see 
Sec. 430.3).
    2.5.2 Fan type vented room heaters and floor furnaces. During tests 
on fan type furnaces and heaters, adjust the air flow through the heater 
as specified by the manufacturer. If adjustable air discharge registers 
are provided, adjust them to provide the maximum possible air 
restriction.
    2.6 Location of temperature measuring instrumentation.
    2.6.1 Gas fueled vented home heating equipment (including direct 
vent systems). For units employing an integral draft diverter, install 
nine thermocouples, wired in parallel, in a horizontal plane in the five 
foot test stack located one foot from the test stack inlet. Equalize the 
length of all thermocouple leads before paralleling. Locate one 
thermocouple in the center of the stack. Locate eight thermocouples 
along imaginary lines intersecting at right angles in this horizontal 
plane at points one third and two thirds of the distance between the 
center of the stack and the stack wall.
    For units which employ a direct vent system, locate at least one 
thermocouple at the center of each flue way exiting the heat exchanger. 
Provide radiation shields if the thermocouples are exposed to burner 
radiation.
    For units which employ a draft hood or units which employ a direct 
vent system which does not significantly preheat the incoming combustion 
air, install nine thermocouples, wired in parallel, in a horizontal 
plane located within 12 inches (304.8 mm) of the heater outlet and 
upstream of the draft hood on units so equipped. Locate one thermocouple 
in the center of the pipe and eight thermocouples along imaginary lines 
intersecting at right angles in this horizontal plane at points one 
third and two thirds of the distance between the center of the pipe and 
the pipe wall.
    For units which employ direct vent systems that significantly 
preheat the incoming combustion air, install nine thermocouples, wired 
in parallel, in a plane parallel to and located within 6 inches (152.4 
mm) of the vent/air intake terminal. Equalize the length of all 
thermocouple leads before paralleling. Locate one thermocouple in the 
center of the vent pipe and eight thermocouples along imaginary lines 
intersecting at right angles in this plane at points one third and two 
thirds of the distance between the center of the flue pipe and the pipe 
wall.
    Use bead-type thermocouples having wire size not greater than No. 24 
American Wire Gauge (AWG). If there is a possibility that the 
thermocouples could receive direct radiation from the fire, install 
radiation shields on the fire side of the thermocouples only and 
position the shields so that they do not touch the thermocouple 
junctions.
    Install thermocouples for measuring conditioned warm air temperature 
as described in Part VIII section 8.7 of ANSI Z21.86 (incorporated by 
reference, see Sec. 430.3). Establish the temperature of the inlet air 
by means of single No. 24 AWG bead-type thermocouple, suitably shielded 
from direct radiation and located in the center of the plane of each 
inlet air opening.
    2.6.2 Oil fueled vented home heating equipment (including direct 
vent systems). Install nine thermocouples, wired in parallel and having 
equal length leads, in a plane perpendicular to the axis of the flue 
pipe. Locate this plane at the position shown in Figure 36.4 of UL 730, 
or Figure 38.1 and 38.2 of UL 729 (incorporated by reference, see Sec. 
430.3) for a single thermocouple, except that on direct vent systems 
which significantly preheat the incoming combustion air, it shall be 
located within 6 inches (152.5 mm) of the outlet of the vent/air intake 
terminal. Locate one thermocouple in the center of the flue pipe and 
eight thermocouples along imaginary lines intersecting at right angles 
in this plane at points one third and two thirds of the distance between 
the center of the pipe and pipe wall.
    Use bead-type thermocouples having a wire size not greater than No. 
24 AWG. If there is a possibility that the thermocouples could receive 
direct radiation from the fire, install radiation shields on the fire 
side of the thermocouples only and position the shields so that they do 
not touch the thermocouple junctions.
    Install thermocouples for measuring the conditioned warm air 
temperature as described in sections 37.5.8 through 37.5.18 of UL 730 
(incorporated by reference, see Sec. 430.3). Establish the temperature 
of the inlet air by means of a single No. 24 AWG bead-type thermocouple, 
suitably shielded

[[Page 653]]

from direct radiation and located in the center of the plane of each 
inlet air opening.
    2.7 Combustion measurement instrumentation. Analyze the samples of 
stack and flue gases for vented heaters to determine the concentration 
by volume of carbon dioxide present in the dry gas with instrumentation 
which will result in a reading having an accuracy of 0.1 percentage points.
    2.8 Energy flow instrumentation. Install one or more instruments, 
which measure the rate of gas flow or fuel oil supplied to the vented 
heater, and if appropriate, the electrical energy with an error no 
greater than one percent.
    2.9 Room ambient temperature. The room ambient temperature shall be 
the arithmetic average temperature of the test area, determined by 
measurement with four No. 24 AWG bead-type thermocouples with junctions 
shielded against radiation, located approximately at 90-degree positions 
on a circle circumscribing the heater or heater enclosure under test, in 
a horizontal plane approximately at the vertical midpoint of the 
appliance or test enclosure, and with the junctions approximately 24 
inches from sides of the heater or test enclosure and located so as not 
to be affected by other than room air.
    The value TRA is the room ambient temperature measured at 
the last of the three successive readings taken 15 minutes apart 
described in section 3.1.1 or 3.1.2 as applicable. During the time 
period required to perform all the testing and measurement procedures 
specified in section 3.0 of this appendix, maintain the room ambient 
temperature within 5 [deg]F (2.8 C) of the value TRA. At no time during 
these tests shall the room ambient temperature exceed 100 [deg]F (37.8 
C) or fall below 65 [deg]F (18.3 C).
    Locate a thermocouple at each elevation of draft relief inlet 
opening and combustion air inlet opening at a distance of approximately 
24 inches from the inlet openings. The temperature of the air for 
combustion and the air for draft relief shall not differ more than 
5 [deg]F from the room ambient temperature as 
measured above at any point in time. This requirement for combustion air 
inlet temperature does not need to be met once the burner is shut off 
during the testing described in sections 3.3 and 3.6 of this appendix.
    2.10 Equipment used to measure mass flow rate in flue and stack. The 
tracer gas chosen for this task should have a density which is less than 
or approximately equal to the density of air. Use a gas unreactive with 
the environment to be encountered. Using instrumentation of either the 
batch or continuous type, measure the concentration of tracer gas with 
an error no greater than 2 percent of the value of the concentration 
measured.
    2.11 Equipment with multiple control modes. For equipment that has 
both manual and automatic thermostat control modes, test the unit 
according to the procedure for its automatic control mode, i.e. single-
stage, two stage, or step-modulating.

                      3.0 Testing and measurements.

    3.1 Steady-state testing.
    3.1.1 Gas fueled vented home heating equipment (including direct 
vent systems). Set up the vented heater as specified in sections 2.1, 
2.2, and 2.3 of this appendix. The draft diverter shall be in the normal 
open condition and the stack shall not be insulated. (Insulation of the 
stack is no longer required for the vented heater test.) Begin the 
steady-state performance test by operating the burner and the 
circulating air blower, on units so equipped, with the adjustments 
specified by sections 2.4.1 and 2.5 of this appendix, until steady-state 
conditions are attained as indicated by three successive readings taken 
15 minutes apart with a temperature variation of not more than 3 [deg]F (1.7 C) in the stack gas temperature for vented 
heaters equipped with draft diverters or 5 [deg]F 
(2.8 C) in the flue gas temperature for vented heaters equipped with 
either draft hoods or direct vent systems. The measurements described in 
this section are to coincide with the last of these 15 minute readings.
    On units employing draft diverters, measure the room temperature 
(TRA) as described in section 2.9 of this appendix and 
measure the steady-state stack gas temperature (TS,SS) using 
the nine thermocouples located in the 5 foot test stack as specified in 
section 2.6.1 of this appendix. Secure a sample of the stack gases in 
the plane where TS,SS is measured or within 3.5 feet 
downstream of this plane. Determine the concentration by volume of 
carbon dioxide (XCO2S) present in the dry stack gas. If the 
location of the gas sampling differs from the temperature measurement 
plane, there shall be no air leaks through the stack between these two 
locations.
    On units employing draft hoods or direct vent systems, measure the 
room temperature (TRA) as described in section 2.9 of this 
appendix and measure the steady-state flue gas temperature 
(TF,SS), using the nine thermocouples located in the flue 
pipe as described in section 2.6.1 of this appendix. Secure a sample of 
the flue gas in the plane of temperature measurement and determine the 
concentration by volume of CO2 (XCO2F) present in 
dry flue gas. In addition, for units employing draft hoods, secure a 
sample of the stack gas in a horizontal plane in the five foot test 
stack located one foot from the test stack inlet; and determine the 
concentration by volume of CO2 (XCO2S) present in 
dry stack gas.
    Determine the steady-state heat input rate (Qin) including pilot gas 
by multiplying the measured higher heating value of the test gas by the 
steady-state gas input rate corrected to standard conditions of 60 
[deg]F and 30

[[Page 654]]

inches of mercury. Use measured values of gas temperature and pressure 
at the meter and the barometric pressure to correct the metered gas flow 
rate to standard conditions.
    After the above test measurements have been completed on units 
employing draft diverters, secure a sample of the flue gases at the exit 
of the heat exchanger(s) and determine the concentration of 
CO2 (XCO2F) present. In obtaining this sample of 
flue gas, move the sampling probe around or use a sample probe with 
multiple sampling ports in order to assure that an average value is 
obtained for the CO2 concentration. For units with multiple 
heat exchanger outlets, measure the CO2 concentration in a 
sample from each outlet to obtain the average CO2 
concentration for the unit. A manifold (parallel connected sampling 
tubes) may be used to obtain this sample.
    For heaters with single-stage thermostat control (wall mounted 
electric thermostats), determine the steady-state efficiency at the 
maximum fuel input rate as specified in section 2.4 of this appendix.
    For gas fueled vented heaters equipped with either two stage control 
or step-modulating control, determine the steady-state efficiency at the 
maximum fuel input rate and at the reduced fuel input rate, as specified 
in section 2.4.1 of this appendix.
    For manually controlled gas fueled vented heaters with various input 
rates, determine the steady-state efficiency at a fuel input rate that 
is within 5 percent of 50 percent of the maximum 
rated fuel input rate as indicated on the nameplate of the unit or in 
the manufacturer's installation and operation manual shipped with the 
unit. If the heater is designed to use a control that precludes 
operation at other than maximum rated fuel input rate (single firing 
rate) determine the steady state efficiency at the maximum rated fuel 
input rate only.
    3.1.2 Oil fueled vented home heating equipment (including direct 
vent systems). Set up and adjust the vented heater as specified in 
sections 2.1, 2.2, and 2.3.4 of this appendix. Begin the steady-state 
performance test by operating the burner and the circulating air blower, 
on units so equipped, with the adjustments specified by sections 2.4.2 
and 2.5 of this appendix, until steady-state conditions are attained as 
indicated by a temperature variation of not more than 5 [deg]F (2.8 C) in the flue gas temperature in three 
successive readings taken 15 minutes apart. The measurements described 
in this section are to coincide with the last of these 15 minutes 
readings.
    For units equipped with power burners, do not allow smoke in the 
flue to exceed a No. 1 smoke during the steady-state performance test as 
measured by the procedure described in ASTM D2156 (incorporated by 
reference, see Sec. 430.3). Maintain the average draft over the fire 
and in the breeching during the steady-state performance test at that 
recommended by the manufacturer 0.005 inches of 
water gauge.
    Measure the room temperature (TRA) as described in 
section 2.9 of this appendix. Measure the steady-state flue gas 
temperature (TF,SS) using nine thermocouples located in the 
flue pipe as described in section 2.6.2 of this appendix. From the plane 
where TF,SS was measured, collect a sample of the flue gas 
and determine the concentration by volume of CO2 
(XCO2F) present in dry flue gas. Measure and record the 
steady-state heat input rate (Qin).
    For manually controlled oil fueled vented heaters, determine the 
steady-state efficiency at a fuel input rate that is within 5 percent of 50 percent of the maximum fuel input rate; 
or, if the design of the heater is such that the fuel input rate cannot 
be set to 5 percent of 50 percent of the maximum 
rated fuel input rate, determine the steady-state efficiency at the 
minimum rated fuel input rate as measured in section 3.1.2 of this 
appendix for manually controlled oil fueled vented heaters.
    3.1.3 Auxiliary Electric Power Measurement. Allow the auxiliary 
electrical system of a gas or oil vented heater to operate for at least 
five minutes before recording the maximum auxiliary electric power 
measurement from the wattmeter. Record the maximum electric power 
(PE) expressed in kilowatts. For vented heaters with 
modulating controls, the recorded (PE) shall be maximum 
measured electric power multiplied by the following factor (R). For two 
stage controls, R = 1.3. For step modulating controls, R = 1.4 when the 
ratio of minimum-to-maximum fuel input is greater than or equal to 0.7, 
R = 1.7 when the ratio of minimum-to-maximum fuel input is less than 0.7 
and greater than or equal to 0.5, and R = 2.2 when the ratio of minimum-
to-maximum fuel input is less than 0.5.
    3.2 Jacket loss measurement. Conduct a jacket loss test for vented 
floor furnaces. Measure the jacket loss (Lj) in accordance 
with ASHRAE 103-2007 section 8.6 (incorporated by reference, see Sec. 
430.3), applying the provisions for furnaces and not the provisions for 
boilers.
    3.3 Measurement of the off-cycle losses for vented heaters equipped 
with thermal stack dampers. Unless specified otherwise, the thermal 
stack damper should be at the draft diverter exit collar. Attach a five 
foot length of bare stack to the outlet of the damper. Install 
thermocouples as specified in section 2.6.1 of this appendix.
    For vented heaters equipped with single-stage thermostats, measure 
the off-cycle losses at the maximum fuel input rate. For vented heaters 
equipped with two stage thermostats, measure the off-cycle losses at the 
maximum fuel input rate and at the reduced

[[Page 655]]

fuel input rate. For vented heaters equipped with step-modulating 
thermostats, measure the off-cycle losses at the reduced fuel input 
rate.
    Allow the vented heater to heat up to a steady-state condition. Feed 
a tracer gas at a constant metered rate into the stack directly above 
and within one foot above the stack damper. Record tracer gas flow rate 
and temperature. Measure the tracer gas concentration in the stack at 
several locations in a horizontal plane through a cross-section of the 
stack at a point sufficiently above the stack damper to ensure that the 
tracer gas is well mixed in the stack.
    Continuously measure the tracer gas concentration and temperature 
during a 10-minute cool-down period. Shut the burner off and immediately 
begin measuring tracer gas concentration in the stack, stack 
temperature, room temperature, and barometric pressure. Record these 
values as the midpoint of each one-minute interval between burner shut-
down and ten minutes after burner shut-down. Meter response time and 
sampling delay time shall be considered in timing these measurements.
    3.4 Measurement of the effectiveness of electro-mechanical stack 
dampers. For vented heaters equipped with electro-mechanical stack 
dampers, measure the cross sectional area of the stack (As), 
the net area of the damper plate (Ao), and the angle that the 
damper plate makes when closed with a plane perpendicular to the axis of 
the stack ([Omega]). The net area of the damper plate means the area of 
the damper plate minus the area of any holes through the damper plate.
    3.5 Pilot light measurement.
    3.5.1 Measure the energy input rate to the pilot light 
(QP) with an error no greater than 3 percent for vented 
heaters so equipped.
    3.5.2 For manually controlled heaters where the pilot light is 
designed to be turned off by the user when the heater is not in use, 
that is, turning the control to the OFF position will shut off the gas 
supply to the burner(s) and to the pilot light, the measurement of 
QP is not needed. This provision applies only if an 
instruction to turn off the unit is provided on the heater near the gas 
control valve (e.g. by label) by the manufacturer.

    3.6 Optional procedure for determining Dp' DF' 
and Ds for systems for all types of vented heaters. For all 
types of vented heaters, Dp' DF' and DS 
can be measured by the following optional cool down test.
    Conduct a cool down test by letting the unit heat up until steady-
state conditions are reached, as indicated by temperature variation of 
not more than 5 [deg]F (2.8 [deg]C) in the flue gas temperature in three 
successive readings taken 15 minutes apart, and then shutting the unit 
off with the stack or flue damper controls by-passed or adjusted so that 
the stack or flue damper remains open during the resulting cool down 
period. If a draft was maintained on oil fueled units in the flue pipe 
during the steady-state performance test described in section 3.1 of 
this appendix, maintain the same draft (within a range of -.001 to + 
.005 inches of water gauge of the average steady-state draft) during 
this cool down period.
    Measure the flue gas mass flow rate (mF,OFF) during the 
cool down test described above at a specific off-period flue gas 
temperature and corrected to obtain its value at the steady-state flue 
gas temperature (TF,SS), using the procedure described below.
    Within one minute after the unit is shut off to start the cool down 
test for determining DF, begin feeding a tracer gas into the 
combustion chamber at a constant flow rate of VT, and at a 
point which will allow for the best possible mixing with the air flowing 
through the chamber. (On units equipped with an oil fired power burner, 
the best location for injecting this tracer gas appears to be through a 
hole drilled in the air tube.) Periodically measure the value of 
VT with an instantaneously reading flow meter having an 
accuracy of 3 percent of the quantity measured. 
Maintain VT at less than 1 percent of the air flow rate 
through the furnace. If a combustible tracer gas is used, there should 
be a delay period between the time the burner gas is shut off and the 
time the tracer gas is first injected to prevent ignition of the tracer 
gas.
    Between 5 and 6 minutes after the unit is shut off to start the cool 
down test, measure at the exit of the heat exchanger the average flue 
gas temperature, T*F,Off. At the same instant the flue gas 
temperature is measured, also measure the percent volumetric 
concentration of tracer gas CT in the flue gas in the same 
plane where T*F,Off is determined. Obtain the concentration 
of tracer gas using an instrument which will result in an accuracy of 
2 percent in the value of CT measured. 
If use of a continuous reading type instrument results in a delay time 
between drawing of a sample and its analysis, this delay should be taken 
into account so that the temperature measurement and the measurement of 
tracer gas concentration coincide. In addition, determine the 
temperature of the tracer gas entering the flow meter (TT) 
and the barometric pressure (PB).
    The rate of the flue gas mass flow through the vented heater and the 
factors DP, DF, and DS are calculated 
by the equations in sections 4.5.1 through 4.5.3 of this appendix.
    3.6.1 Procedure for determining (DF and DP) of 
vented home heating equipment with no measurable airflow. On units whose 
design is such that there is no measurable airflow through the 
combustion chamber and heat exchanger when the burner(s) is off (as 
determined by the test procedure in section 3.6.2 of this appendix), 
DF and DP may be set equal to 0.05.

[[Page 656]]

    3.6.2 Test Method to Determine Whether the Use of the Default Draft 
Factors (DF and DP) of 0.05 is Allowed. 
Manufacturers may use the following test protocol to determine whether 
air flows through the combustion chamber and heat exchanger when the 
burner(s) is off using a smoke stick device. The default draft factor of 
0.05 (as allowed per section 3.6.1 of this appendix) may be used only 
for units determined pursuant to this protocol to have no air flow 
through the combustion chamber and heat exchanger.
    3.6.2.1 Test Conditions. Wait for two minutes following the 
termination of the vented heater's on-cycle.
    3.6.2.2 Location of Test Apparatus
    3.6.2.2.1 After all air currents and drafts in the test chamber have 
been minimized, position the operable smoke stick/pencil as specified, 
based on the following equipment configuration: for horizontal 
combustion air intakes, approximately 4 inches from the vertical plane 
at the termination of the intake vent and 4 inches below the bottom edge 
of the combustion air intake, or for vertical combustion air intakes, 
approximately 4 inches horizontal from vent perimeter at the termination 
of the intake vent and 4 inches down (parallel to the vertical axis of 
the vent). In the instance where the boiler combustion air intake is 
closer than 4 inches to the floor, place the smoke device directly on 
the floor without impeding the flow of smoke.
    3.6.2.2.2 Monitor the presence and the direction of the smoke flow.
    3.6.2.3 Duration of Test. Continue monitoring the release of smoke 
for no less than 30 seconds.
    3.6.2.4 Test Results
    3.6.2.4.1 During visual assessment, determine whether there is any 
draw of smoke into the combustion air intake.
    3.6.2.4.2 If absolutely no smoke is drawn into the combustion air 
intake, the vented heater meets the requirements to allow use of the 
default draft factor of 0.05 pursuant to Section 8.8.3 and/or 9.10 of 
ASHRAE 103-2007 (incorporated by reference, see Sec. 430.3).
    3.6.2.4.3 If there is any smoke drawn into the intake, use of 
default draft factor of 0.05 is prohibited. Proceed with the methods of 
testing as prescribed in section 3.6 of this appendix, or select the 
appropriate default draft factor from Table 1.
    3.7 Measurement of electrical standby mode and off mode power.
    3.7.1 Standby power measurements. With all electrical auxiliaries of 
the vented heater not activated, measure the standby power 
(PW,SB) in accordance with the procedures in IEC 62301 
(Second Edition) (incorporated by reference, see Sec. 430.3), except 
that section 2.9, Room ambient temperature, and the voltage provision of 
section 2.3.5, Electrical supply, of this appendix shall apply in lieu 
of the IEC 62301 (Second Edition) corresponding sections 4.2, Test room, 
and 4.3, Power supply. Clarifying further, the IEC 62301 (Second 
Edition) sections 4.4, Power measuring instruments, and section 5, 
Measurements, shall apply in lieu of section 2.8, Energy flow 
instrumentation, of this appendix. Measure the wattage so that all 
possible standby mode wattage for the entire appliance is recorded, not 
just the standby mode wattage of a single auxiliary. The recorded 
standby power (PW,SB) shall be rounded to the second decimal 
place, and for loads greater than or equal to 10W, at least three 
significant figures shall be reported.
    3.7.2 Off mode power measurement. If the unit is equipped with a 
seasonal off switch or there is an expected difference between off mode 
power and standby mode power, measure off mode power (PW,OFF) 
in accordance with the standby power procedures in IEC 62301 (Second 
Edition) (incorporated by reference, see Sec. 430.3), except that 
section 2.9, Room ambient temperature, and the voltage provision of 
section 2.3.5, Electrical supply, of this appendix shall apply in lieu 
of the IEC 62301 (Second Edition) corresponding sections 4.2, Test room, 
and 4.3, Power supply. Clarifying further, the IEC 62301 (Second 
Edition) sections 4.4, Power measuring instruments, and section 5, 
Measurements, shall apply in lieu of section 2.8, Energy flow 
instrumentation, of this appendix. Measure the wattage so that all 
possible off mode wattage for the entire appliance is recorded, not just 
the off mode wattage of a single auxiliary. If there is no expected 
difference in off mode power and standby mode power, let 
PW,OFF = PW,SB, in which case no separate 
measurement of off mode power is necessary. The recorded off mode power 
(PW,OFF) shall be rounded to the second decimal place, and 
for loads greater than or equal to 10W, at least three significant 
figures shall be reported.
    3.8 Condensing vented heaters--measurement of condensate under 
steady-state and cyclic conditions. Attach condensate drain lines to the 
vented heater as specified in the manufacturer's I&O manual provided 
with the unit. The test unit shall be level prior to all testing. A 
continuous downward slope of drain lines from the unit shall be 
maintained. The drain lines must facilitate uninterrupted flow of 
condensate during the test. The condensate collection container must be 
glass or polished stainless steel to facilitate removal of interior 
deposits. The collection container shall have a vent opening to the 
atmosphere, be dried prior to each use, and be at room ambient 
temperature. The humidity of the room air shall at no time exceed 80 
percent relative humidity. For condensing units not designed for

the optional tracer gas procedures of sections 3.3 and 3.6 of this 
appendix shall only conduct the steady-state condensate collection test.
    3.8.1 Steady-state condensate collection test. Begin steady-state 
condensate collection concurrently with or immediately after completion 
of the steady-state testing of section 3.1 of this appendix. The steady-
state condensate collection period shall be 30 minutes. Condensate mass 
shall be measured immediately at the end of the collection period to 
minimize evaporation loss from the sample. Record fuel input during the 
30-minute condensate collection steady-state test period. Measure and 
record fuel higher heating value (HHV), temperature, and pressures 
necessary for determining fuel energy input (Qc,ss). The fuel 
quantity and HHV shall be measured with errors no greater than 1 percent. Determine the mass of condensate for the 
steady-state test (Mc,ss) in pounds by subtracting the tare 
container weight from the total container and condensate weight measured 
at the end of the 30-minute condensate collection test period. The error 
associated with the mass measurement instruments shall not exceed 0.5 percent of the quantity measured.
    For units with step-modulating or two stage controls, the steady-
state condensate collection test shall be conducted at both the maximum 
and reduced input rates.
    3.8.2 Cyclic condensate collection tests. If existing controls do 
not allow for cyclical operation of the tested unit, control devices 
shall be installed to allow cyclical operation of the vented heater. Run 
three consecutive test cycles. For each cycle, operate the unit until 
flue gas temperatures at the end of each on-cycle, rounded to the 
nearest whole number, are within 5 [deg]F of each other for two 
consecutive cycles. On-cycle and off-cycle times are 4 minutes and 13 
minutes respectively. Control of ON and OFF operation actions shall be 
within 6 seconds of the scheduled time. For fan-
type vented heaters, maintain circulating air adjustments as specified 
in section 2.5 of this appendix. Begin condensate collection at one 
minute before the on-cycle period of the first test cycle. Remove the 
container one minute before the end of each off-cycle period. Measure 
condensate mass for each test-cycle. The error associated with the mass 
measurement instruments shall not exceed 0.5 
percent of the quantity measured.
    Fuel input shall be recorded during the entire test period starting 
at the beginning of the on-time period of the first cycle to the 
beginning of the on-time period of the second cycle, from the beginning 
of the on-time period of the second cycle to the beginning of the on-
time period of the third cycle, etc., for each of the test cycles. Fuel 
HHV, temperature, and pressure necessary for determining fuel energy 
input, Qc, shall be recorded. Determine the mass of 
condensate for each cycle, Mc, in pounds. If at the end of 
three cycles, the sample standard deviation is within 20 percent of the 
mean value for three cycles, use total condensate collected in the three 
cycles as Mc; if not, continue collection for an additional 
three cycles and use the total condensate collected for the six cycles 
as Mc. Determine the fuel energy input, Qc, during 
the three or six test cycles, expressed in Btu.

   Sec. Appendix P to Subpart B of Part 430--Uniform Test Method for 
            Measuring the Energy Consumption of Pool Heaters

    Note: On and after July 6, 2015, any representations made with 
respect to the energy use or efficiency of all pool heaters must be made 
in accordance with the results of testing pursuant to this appendix. On 
and after this date, if a manufacturer makes representations of standby 
mode and off mode energy consumption, then testing must also include the 
provisions of this appendix related to standby mode and off mode energy 
consumption. Until July 6, 2015, manufacturers must test gas-fired pool 
heaters in accordance with this appendix, or appendix P as it appeared 
at 10 CFR part 430, subpart B revised as of January 1, 2014. Any 
representations made with respect to the energy use or efficiency of 
such pool heaters must be in accordance with whichever version is 
selected. DOE notes that, because testing under this appendix P must be 
completed as of July 6, 2015, manufacturers may wish to begin using this 
test procedure immediately.

insufficient length to reach both ends of lamp, additional wire may be 
added. Add the minimum additional wire length necessary, and the 
additional wire must be the same wire gauge as the wire supplied with 
the ballast. If no wiring is provided with the ballast, 18 gauge or 
thicker wire must be used. The wires must be separated from each other

2.3.1.7 and its subsections), ballasts designed and marketed to operate 
both T8 and T12 lamps must be tested with T8 lamps.
    2.3.1.7. For sign ballasts (as defined in section 1.18):
    2.3.1.7.1. Use a T8 lamp as specified in Table A of this section for 
sign ballasts that are designed and marketed to operate only T8 lamps.
    2.3.1.7.2. Use a T12 lamp as specified in Table A of this section 
for sign ballasts that are designed and marketed to operate only T12 
lamps.
    2.3.1.7.3. Use a T12 lamp as specified in Table A of this section 
for sign ballasts that are designed and marketed to operate both T8 and 
T12 lamps.
    2.3.1.8. Test each ballast with the lamp type specified in Table A 
of this section that corresponds to the lamp diameter the ballast is 
designed and marketed to operate. Test each ballast with only one lamp 
type.

be held at 25 2 [deg]C, with minimal air movement 
as defined in ANSI C78.375 (incorporated by reference; see Sec. 430.3).
    2.4.3. Input Voltage. Disregard the directions in ANSI C82.2 
(incorporated by reference; see Sec. 430.3) section 4.1, and use the 
following directions for input voltage instead. For ballasts designed 
and marketed for operation at multiple voltages that are not residential 
ballasts, test the ballast at 277V 0.1%. For 
residential ballasts designed and marketed for operation at multiple 
voltages, test the ballast at 120V 0.1%. For sign 
ballasts designed and marketed for operation at multiple voltages, test 
the ballast at 120V 0.1%. Ballasts designed and 
marketed for operation at only one input voltage must be tested at that 
specified voltage.

to operate at full output, measure each of the parameters described in 
sections 2.5.1.3 through 2.5.1.9 concurrently.
    2.5.1.2.1. Stable operating conditions are determined by measuring 
lamp arc voltage, current, and power once per second in accordance with 
the setup described in section 2.3. Once the difference between the 
maximum and minimum values for lamp arc voltage, current, and power do 
not exceed one percent over a four minute moving window, the system is 
considered stable.

    [GRAPHIC] [TIFF OMITTED] TR05JN15.028
    
Where: Total Lamp Arc Power is the sum of the lamp arc powers for all 
lamps operated by the ballast as determined by section 2.5.1.5, Input 
Power is as determined by section 2.5.1.6, and [beta] is equal to the 
frequency adjustment factor in Table A.

                        3. Standby Mode Procedure

    3.1. The measurement of standby mode power need not be performed to 
determine compliance with energy conservation standards for fluorescent 
lamp ballasts at this time. On or after December 2, 2015, if a 
manufacturer makes any representations with respect to the standby mode 
power use of fluorescent lamp ballasts, then testing must also include 
the provisions of this test procedure related to standby mode energy 
consumption.

                          3.2. Test Conditions

    3.2.1. The test conditions for testing fluorescent lamp ballasts 
must be established in accordance with ANSI C82.2 (incorporated by 
reference; see Sec. 430.3). The test conditions for measuring standby 
power are described in sections 5, 7, and 8 of ANSI C82.2. Fluorescent 
lamp ballasts that are designed and marketed for connection to control 
devices must be tested with all commercially available compatible 
control devices connected in all possible configurations. For each 
configuration, a separate measurement of standby power must be made in 
accordance with section 3.3 of the test procedure.

                    3.3. Test Method and Measurements

    3.3.1. The test for measuring standby mode energy consumption of 
fluorescent lamp ballasts must be done in accordance with ANSI C82.2 
(incorporated by reference; see Sec. 430.3).
    3.3.2. Send a signal to the ballast instructing it to have zero 
light output using the appropriate ballast communication protocol or 
system for the ballast being tested.
    3.3.3. Input Power. Measure the input power (watts) to the ballast 
in accordance with ANSI C82.2, section 13, (incorporated by reference; 
see Sec. 430.3).

must be measured using all applicable methods described below.
    3.3.4.1. AC Control Signal. Measure the AC control signal power 
(watts), using a wattmeter (W), connected to the ballast in accordance 
with the circuit shown in Figure 4 of this section.
[GRAPHIC] [TIFF OMITTED] TR05JN15.030

    3.3.4.2. DC Control Signal. Measure the DC control signal voltage, 
using a voltmeter (V), and current, using an ammeter (A), connected to 
the ballast in accordance with the circuit shown in Figure 5 of this 
section. The DC control signal power is calculated by multiplying the DC 
control signal voltage and the DC control signal current.

[[Page 682]]


    3.3.4.3. Power Line Carrier (PLC) Control Signal. Measure the PLC 
control signal power (watts) using a wattmeter (W) connected to the 
ballast in accordance with the circuit shown in Figure 6 of this 
section. The wattmeter must have a frequency response that is at least 
10 times higher than the PLC being measured in order to measure the PLC 
signal correctly. The wattmeter must also be high-pass filtered to 
filter out power at 60 Hertz.
[GRAPHIC] [TIFF OMITTED] TR05JN15.032

    3.3.4.4. Wireless Control Signal. The power supplied to a ballast 
using a wireless signal is not easily measured but is estimated to be 
well below 1.0 watt. Therefore, the wireless control signal power is not 
measured as part of this test procedure.

    2. Scope:
    The provisions in this appendix apply to ceiling fans except:
    (1) Ceiling fans where the plane of rotation of a ceiling fan's 
blades is not less than or equal to 45 degrees from horizontal, or 
cannot be adjusted based on the manufacturer's specifications to be less

    (4) Oscillating ceiling fans.
    3. General Instructions, Test Apparatus, and Test Measurement:
    The test apparatus and test measurement used to determine energy 
performance depend on the ceiling fan's blade span. For each tested 
ceiling fan, measure the lateral distance from the center of the axis of 
rotation of the fan blades to the furthest fan blade edge from the 
center of the axis of rotation, and multiply this distance by two. The 
blade span for a basic model of ceiling fan is then calculated as the 
arithmetic mean of this distance across each ceiling fan in the sample, 
rounded to the nearest inch.
    3.1. General instructions.
    3.1.1. Record measurements at the resolution of the test 
instrumentation. Round off calculations to the number of significant 
digits present at the resolution of the test instrumentation, except for 
blade span, which is rounded to the nearest inch. Round the final 
ceiling fan efficiency value to the nearest whole number as follows:
    3.1.1.1. A fractional number at or above the midpoint between the 
two consecutive whole numbers shall be rounded up to the higher of the 
two whole numbers; or
    3.1.1.2. A fractional number below the midpoint between the two 
consecutive whole numbers shall be rounded down to the lower of the two 
whole numbers.
    3.1.2. For multi-head ceiling fans, the effective blade span is the 
blade span (as specified in section 3) of an individual fan head, if all 
fan heads are the same size. If the fan heads are of varying sizes, the 
effective blade span is the blade span (as specified in section 3) of 
the largest fan head.
    3.2. Test apparatus for low-speed small-diameter and high-speed 
small-diameter ceiling fans: All instruments are to have accuracies 
within 1% of reading, except for the air velocity 
sensors, which must have accuracies within 5% of 
reading or 2 feet per minute (fpm), whichever is greater. Equipment is 
to be calibrated at least once a year to compensate for variation over 
time.
    3.2.1. Air Delivery Room Requirements
    (1) The air delivery room dimensions are to be 20  0.75 feet x 20  0.75 feet with an 
11  0.75 foot-high ceiling. The control room shall 
be constructed external to the air delivery room.
    (2) The ceiling shall be constructed of sheet rock or stainless 
plate. The walls must be of adequate thickness to maintain the specified 
temperature and humidity during the test. The paint used on the walls, 
as well as the paint used on the ceiling material, must be of a type 
that minimizes absorption of humidity and that keeps the temperature of 
the room constant during the test (e.g., oil-based paint).
    (3) The room must not have any ventilation other than an air 
conditioning and return system used to control the temperature and 
humidity of the room. The construction of the room must ensure 
consistent air circulation patterns within the room. Vents must have 
electronically-operated damper doors controllable from a switch outside 
of the testing room.
    3.2.2. Equipment Set-Up
    (1) Make sure the transformer power is off. Hang the ceiling fan to 
be tested directly from the ceiling, according to the manufacturer's 
installation instructions. Hang all non-multi-mount ceiling fans in the 
fan configuration that minimizes the distance between the ceiling and 
the lowest point of the fan blades. Hang and test multi-mount fans in 
two configurations: The configuration associated with the definitions of 
a standard fan that minimizes the distance between the ceiling and the 
lowest point of the fan blades and the configuration associated with the 
definition of a hugger fan that minimizes the

[[Page 688]]

distance between the ceiling and the lowest point of the fan blades.
    (2) Connect wires as directed by manufacturer's wiring instructions. 
Note: Assemble fan prior to the test; lab personnel must follow the 
instructions provided with the fan by the fan manufacturer. Balance the 
fan blade assembly in accordance with the manufacturer's instructions to 
avoid excessive vibration of the motor assembly (at any speed) during 
operation.
    (3) With the ceiling fan installed, adjust the height of the air 
velocity sensors to ensure the vertical distance between the lowest 
point on the ceiling fan blades and the air velocity sensors is 43 
inches.
    (4) Either a rotating sensor arm or four fixed sensor arms can be 
used to take airflow measurements along four axes, labeled A-D. Axes A, 
B, C, and D are at 0, 90, 180, and 270 degree positions. Axes A-D must 
be perpendicular to the four walls of the room. See Figure 1 of this 
appendix.
[GRAPHIC] [TIFF OMITTED] TR25JY16.005

    (5) Minimize the amount of exposed wiring. Store all sensor lead 
wires under the floor, if possible.
    (6) Place the sensors at intervals of 4  
0.0625 inches along a sensor arm, starting with the first sensor at the 
point where the four axes intersect. Do not touch the actual sensor 
prior to testing. Use enough sensors to record air delivery within a 
circle 8 inches larger in diameter than the blade span of the ceiling 
fan being tested. The experimental set-up is shown in Figure 2 of this 
appendix.

[[Page 689]]

    (7) Table 1 of this appendix shows the appropriate number of sensors 
needed per each of four axes (including the first sensor at the 
intersection of the axes) for common fan sizes.

------------------------------------------------------------------------
* The fan sizes listed are illustrative and do not restrict which
  ceiling fan sizes can be tested.

    (8) Install an RPM (revolutions per minute) meter, or tachometer, to 
measure RPM of the ceiling fan blades.
    (9) Use an RMS sensor capable of measuring power with an accuracy of 
1% to measure ceiling fan power consumption. If 
the ceiling fan operates on multi-phase power input, measure the active 
(real) power in all phases simultaneously. Measure test voltage within 
6'' of the connection supplied with the ceiling fan.
    (10) Complete any conditioning instructions provided in the ceiling 
fan's instruction or installation manual must be completed prior to 
conducting testing.
    3.2.3. Multi-Head Ceiling Fan Test Set-Up
    Hang a multi-headed ceiling fan from the ceiling such that one of 
the ceiling fan heads is centered directly over sensor 1 (i.e., at the 
intersection of axes A, B, C, and D). The distance between the lowest 
point any of the fan blades of the centered fan head can reach and the 
air velocity sensors is to be such that it is the same as for all other 
small-diameter ceiling fans (see Figure 2 of this appendix). If the 
multi-head ceiling fan has an oscillating function (i.e., the fan heads 
change their axis of rotation relative to the ceiling) that can be 
switched off, switch it off prior to taking airflow measurements. If any 
multi-head fan does not come with the blades preinstalled, install fan 
blades only on the fan head that will be directly centered over the 
intersection of the sensor axes. (Even if the fan heads in a multi-head 
ceiling fan would typically oscillate when the blades are installed on 
all fan heads, the ceiling fan is subject to this test procedure if the 
centered fan head does not oscillate when it is the only fan head with 
the blades installed.) If the fan blades are preinstalled on all fan 
heads, measure airflow in accordance with section 3.3 except only turn 
on the centered fan head. Measure the power consumption measurements are 
to be made separately, with the fan blades installed on all fan heads

[[Page 690]]

and with any oscillating function, if present, switched on.
    3.2.4. Test Set-Up for Ceiling Fans with Airflow Not Directly 
Downward
    For ceiling fans where the airflow is not directly downward, adjust 
the ceiling fan head such that the airflow is as vertical as possible 
prior to testing. For ceiling fans where a fully vertical orientation of 
airflow cannot be achieved, orient the ceiling fan (or fan head, if the 
ceiling fan is a multi-head fan) such that any remaining tilt is aligned 
along one of the four sensor axes. Instead of measuring the air velocity 
for only those sensors directly beneath the ceiling fan, the air 
velocity is to be measured at all sensors along that axis, as well as 
the axis oriented 180 degrees with respect to that axis. For example, if 
the tilt is oriented along axis A, air velocity measurements are to be 
taken for all sensors along the A-C axis. No measurements would need to 
be taken along the B-D axis in this case. All other aspects of test set-
up remain unchanged from sections 3 through 3.2.2.
    3.3. Active mode test measurement for low-speed small-diameter and 
high-speed small-diameter ceiling fans.
    3.3.1. Test conditions to be followed when testing:
    (1) Maintain the room temperature at 70 degrees  5 degrees Fahrenheit and the room humidity at 50% 
 5% relative humidity during the entire test 
process.
    (2) If present, the ceiling fan light fixture is to be installed but 
turned off during testing.
    (3) If present, any heater is to be installed but turned off during 
testing.
    (4) If present, turn off any oscillating function causing the axis 
of rotation of the fan head(s) to change relative to the ceiling during 
operation prior to taking airflow measurements. Turn on any oscillating 
function prior to taking power measurements.
    (5) The supply voltage shall be:
    (i) 120 V if the ceiling fan's minimum rated voltage is 120 V or the 
lowest rated voltage range contains 120 V,
    (ii) 240 V if the ceiling fan's minimum rated voltage is 240 V or 
the lowest rated voltage range contains 240 V, or
    (iii) The ceiling fan's minimum rated voltage (if a voltage range is 
not given) or the mean of the lowest rated voltage range, in all other 
cases. The test voltage shall not vary by more than 1% during the tests.
    (6) Test ceiling fans rated for operation with only a single- or 
multi-phase power supply with single- or multi-phase electricity, 
respectively. Measure active (real) power in all phases continuously 
when testing. Test ceiling fans capable of operating with single- and 
multi-phase electricity with single-phase electricity. DOE will allow 
manufacturers of ceiling fans capable of operating with single- and 
multi-phase electricity to test such fans with multi-phase power and 
make representations of efficiency associated with both single and 
multi-phase electricity if a manufacturer desires to do so, but the test 
results in the multi-phase configuration will not be valid to assess 
compliance with any amended energy conservation standard.
    (7) Conduct the test with the fan connected to a supply circuit at 
the rated frequency.
    (8) Measure power input at a point that includes all power-consuming 
components of the ceiling fan (but without any attached light kit or 
heater energized).
    3.3.2. Airflow and Power Consumption Testing Procedure:
    Measure the airflow (CFM) and power consumption (W) for HSSD ceiling 
fans until stable measurements are achieved, measuring at high speed 
only. Measure the airflow and power consumption for LSSD ceiling fans 
until stable measurements are achieved, measuring first at low speed and 
then at high speed. Airflow and power consumption measurements are 
considered stable if:
    (1) The average air velocity for all axes for each sensor varies by 
less than 5% compared to the average air velocity measured for that same 
sensor in a successive set of air velocity measurements, and
    (2) Average power consumption varies by less than 1% in a successive 
set of power consumption measurements. These stability criteria are 
applied differently to ceiling fans with airflow not directly downward. 
See section 4.1.2 of this appendix.
    Step 1: Set the first sensor arm (if using four fixed arms) or 
single sensor arm (if using a single rotating arm) to the 0 degree 
Position (Axis A). If necessary, use a marking as reference. If using a 
single rotating arm, adjust the sensor arm alignment until it is at the 
0 degree position by remotely controlling the antenna rotator.
    Step 2: Set software up to read and record air velocity, expressed 
in feet per minute (FPM) in 1 second intervals. (Temperature does not 
need to be recorded in 1 second intervals.) Record current barometric 
pressure.
    Step 3: Allow test fan to run 15 minutes at rated voltage and at 
high speed if the ceiling fan is an HSSD ceiling fan. If the ceiling fan 
is an LSSD ceiling fan, allow the test fan to run 15 minutes at the 
rated voltage and at low speed. Turn off all forced-air environmental 
conditioning equipment entering the chamber (e.g., air conditioning), 
close all doors and vents, and wait an additional 3 minutes prior to 
starting test session.
    Step 4: Begin recording readings. Take 100 airflow velocity readings 
(100 seconds run-time) and save these data. If using a rotating sensor 
arm, this is axis A. For all fans except multi-head fans and fans 
capable of oscillating, measure power during the interval that air 
velocity measurements are taken.

[[Page 691]]

Record the average value of the power measurement in watts (W).
    Step 5: Similarly, take 100 air velocity readings (100 seconds run-
time) for Axes B, C, and D; save these data as well. Measure power as 
described in Step 4. If using four fixed sensor arms, take the readings 
for all sensor arms simultaneously.
    Step 6: Repeat Steps 4 and 5 until stable measurements are achieved.
    Step 7: Repeat steps 1 through 6 above on high fan speed for LSSD 
ceiling fans. Note: Ensure that temperature and humidity readings are 
maintained within the required tolerances for the duration of the test 
(all tested speeds). Forced-air environmental conditioning equipment may 
be used and doors and vents may be opened between test sessions to 
maintain environmental conditions.
    Step 8: If testing a multi-mount ceiling fan, repeat steps 1 through 
7 with the ceiling fan in the ceiling fan configuration (associated with 
either hugger or standard ceiling fans) not already tested.
    If a multi-head ceiling fan includes more than one category of 
ceiling fan head, then test at least one of each unique category. A fan 
head with different construction that could affect air movement or power 
consumption, such as housing, blade pitch, or motor, would constitute a 
different category of fan head.
    Step 9: For multi-head ceiling fans, measure active (real) power 
consumption in all phases simultaneously at each speed continuously for 
100 seconds with all fan heads turned on, and record the average value 
at each speed in watts (W).
    For ceiling fans with an oscillating function, measure active (real) 
power consumption in all phases simultaneously at each speed 
continuously for 100 seconds with the oscillating function turned on. 
Record the average value of the power measurement in watts (W).
    For both multi-head ceiling fans and fans with an oscillating 
function, repeat power consumption measurement until stable power 
measurements are achieved.
    3.4. Test apparatus for large-diameter ceiling fans:
    The test apparatus and instructions for testing large-diameter 
ceiling fans must conform to the requirements specified in sections 3 
through 7 of AMCA 230-15 (incorporated by reference, see Sec. 430.3), 
with the following modifications:
    3.4.1. The test procedure is applicable to large-diameter ceiling 
fans up to 24 feet in diameter.
    3.4.2. A ``ceiling fan'' is defined as in 10 CFR 430.2.
    3.4.3. The supply voltage shall be (1) 120 V if the ceiling fan's 
minimum rated voltage is 120 V or the lowest rated voltage range 
contains 120 V, (2) 240 V if the ceiling fan's minimum rated voltage is 
240 V or the lowest rated voltage range contains 240 V, or (3) the 
ceiling fan's minimum rated voltage (if a voltage range is not given) or 
the mean of the lowest rated voltage range, in all other cases.
    3.4.4. Test ceiling fans rated for operation with only a single- or 
multi-phase power supply with single- or multi-phase electricity, 
respectively. Test ceiling fans capable of operating with single- and 
multi-phase electricity with multi-phase electricity. DOE will allow 
manufacturers of ceiling fans capable of operating with single- and 
multi-phase electricity to test such fans with single-phase power and 
make representations of efficiency associated with both single and 
multi-phase electricity if a manufacturer desires to do so, but the test 
results in the single-phase configuration will not be valid to assess 
compliance with any amended energy conservation standard.
    3.5. Active mode test measurement for large-diameter ceiling fans:
    (1) Calculate the airflow (CFM) and measure the active (real) power 
consumption (W) in all phases simultaneously for ceiling fans at the 
speeds specified in Table 2.

----------------------------------------------------------------------------------------------------------------
* This corresponds to a ceiling fan, such as a ceiling fan with a variable-frequency drive (VFD) that operates
  over a continuous (rather than discrete) range of speeds.
** All tested speeds are to be weighted equally. Therefore, the weighting shown here for a ceiling fan with
  three available speeds is approximate.

    (2) When testing at speeds other than high speed (i.e., X% speed 
where X is 80, 60, 40, or 20) for ceiling fans that can operate over an 
infinite number of speeds (e.g., ceiling fans with VFDs), ensure the 
average measured RPM is within the greater of 1% of the average RPM at 
high speed or 1 RPM. For example, if the average measured RPM at high 
speed is 50 RPM, for testing at 80% speed the average measured RPM 
should be between 39 RPM and 41 RPM. If the average measured RPM falls 
outside of this tolerance, adjust the ceiling fan speed and repeat the 
test. Calculate the airflow and measure the active (real) power 
consumption in all phases simultaneously in accordance with the test 
requirements specified in sections 8 and 9, AMCA 230-15 (incorporated by 
reference, see Sec. 430.3), with the following modifications:
    3.5.1. Measure active (real) power consumption in all phases 
simultaneously at a point that includes all power-consuming components 
of the ceiling fan (but without any attached light kit or heater 
energized).
    3.5.2. Measure active (real) power consumption in all phases 
simultaneously continuously at the rated voltage that represents normal 
operation over the time period for which the load differential test is 
conducted.
    3.6. Test measurement for standby power consumption.
    (1) Measure standby power consumption if the ceiling fan offers one 
or more of the following user-oriented or protective functions:
    [ballot] [ballot]o The ability to facilitate the activation or 
deactivation of other functions (including active mode) by remote switch 
(including remote control), internal sensor, or timer.
    [ballot] Continuous functions, including information or status 
displays (including clocks), or sensor-based functions.
    (2) Measure standby power consumption after completion of active 
mode testing and after the active mode functionality has been switched 
off (i.e., the rotation of the ceiling fan blades is no longer 
energized). The ceiling fan must remain connected to the main power 
supply and be in the same configuration as in active mode (i.e., any 
ceiling fan light fixture should still be attached). Measure standby 
power consumption according to sections 4 and 5.3.1 through 5.3.2 of IEC 
62301-U (incorporated by reference, see Sec. 430.3) with the following 
modifications:
    3.6.1. Allow 3 minutes between switching off active mode 
functionality and beginning the standby power test. (No additional time 
before measurement is required.)
    3.6.2. Simultaneously in all phases, measure active (real) power 
consumption continuously for 100 seconds, and record the average value 
of the standby power measurement in watts (W).
    3.6.3. Determine power consumption according to section 5.3.2 of IEC 
62301-U, or by using the following average reading method. Note that a 
shorter measurement period may be possible using the sample method in 
section 5.3.2 of IEC 62301-U.
    (1) Connect the product to the power supply and power measuring 
instrument.
    (2) Select the mode to be measured (which may require a sequence of 
operations and could require waiting for the product to automatically 
enter the desired mode) and then monitor the power.
    (3) Calculate the average power using either the average power 
method or the accumulated energy method. For the average power method, 
where the power measuring instrument can record true average power over 
an operator selected period, the average power is taken directly from 
the power measuring instrument. For the accumulated energy method, 
determine the average power by dividing the measured energy by the time 
for the monitoring period. Use units of watt-hours and hours for both 
methods to determine average power in watts.
    4. Calculation of Ceiling Fan Efficiency From the Test Results:
    (1) The efficacy of a ceiling fan is the ceiling fan efficiency (as 
defined in section 1 of this appendix). Calculate two ceiling fan 
efficiencies for multi-mount ceiling fans: One efficiency corresponds to 
the ceiling fan mounted in the configuration associated

[[Page 693]]

with the definition of a hugger ceiling fan, and the other efficiency 
corresponds to the ceiling fan mounted in the configuration associated 
with the definition of a standard ceiling fan.
    (2) Calculate fan efficiency using the average of both sets of 
airflow and power measurements from the successive sets of measurements 
that meet the stability criteria.
    (3) To calculate the measured airflow for HSSD and LSSD ceiling 
fans, multiply the average air velocity measurement at each sensor from 
section 3.3 of this appendix (for high speed for HSSD ceiling fans, and 
for high and low speeds for LSSD ceiling fans) with the sensor's 
effective area (explained below), and then sum the products to obtain 
the overall measured airflow at the tested speed. Using the airflow and 
the power consumption measurements from sections 3.3 and 3.5 of this 
appendix (for all tested settings for large-diameter ceiling fans) 
calculate the efficiency for any ceiling fan as follows:
[GRAPHIC] [TIFF OMITTED] TR25JY16.007

Where:

CFMi = airflow at speed i,
OHi = operating hours at speed i,
Wi = power consumption at speed i,
OHSb = operating hours in standby mode, and
WSb = power consumption in standby mode.

    (4) Table 3 of this appendix specifies the daily hours of operation 
to be used in calculating ceiling fan efficiency:

------------------------------------------------------------------------
* The active mode hours must be apportioned equally across the number of
  active mode speeds tested (e.g., if four speeds are tested, 25% of the
  active mode hours are apportioned to each speed).

    (5) Calculate the effective area corresponding to each sensor used 
in the test method for small-diameter ceiling fans with the following 
equations:
    (6) For sensor 1, the sensor located directly underneath the center 
of the ceiling fan, the effective width of the circle is 2 inches, and 
the effective area is:
[GRAPHIC] [TIFF OMITTED] TR25JY16.008

    (7) For the sensors between sensor 1 and the last sensor used in the 
measurement, the effective area has a width of 4 inches. If a sensor is 
a distance d, in inches, from sensor 1, then the effective area is:
[GRAPHIC] [TIFF OMITTED] TR25JY16.009

    (8) For the last sensor, the width of the effective area depends on 
the horizontal displacement between the last sensor and the

[[Page 694]]

point on the ceiling fan blades furthest radially from the center of the 
fan. The total area included in an airflow calculation is the area of a 
circle 8 inches larger in diameter than the ceiling fan blade span (as 
specified in section 3 of this appendix).
    (9) Therefore, for example, for a 42-inch ceiling fan, the last 
sensor is 3 inches beyond the end of the ceiling fan blades. Because 
only the area within 4 inches of the end of the ceiling fan blades is 
included in the airflow calculation, the effective width of the circle 
corresponding to the last sensor would be 3 inches. The calculation for 
the effective area corresponding to the last sensor would then be:

    (10) For a 46-inch ceiling fan, the effective area of the last 
sensor would have a width of 5 inches, and the effective area would be:

    4.1.1. Ceiling fan efficiency calculations for multi-head ceiling 
fans
    To determine the airflow at a given speed for a multi-head ceiling 
fan, sum the measured airflow for each fan head included in the ceiling 
fan (a single airflow measurement can be applied to identical fan heads, 
but at least one of each unique fan head must be tested). The power 
consumption is the measured power consumption with all fan heads on. 
Using the airflow and power consumption measurements from section 3.3 of 
this appendix, calculate ceiling fan efficiency for a multi-head ceiling 
fan as follows:
[GRAPHIC] [TIFF OMITTED] TR25JY16.012

Where:

CFMi = sum of airflow at a given speed for each head,
OHi = operating hours at a given speed,
Wi = total power consumption at a given speed,
OHSb = operating hours in standby mode, and
WSb = power consumption in standby mode.

    4.1.2. Ceiling fan efficiency calculations for ceiling fans with 
airflow not directly downward
    Using a set of sensors that cover the same diameter as if the 
airflow were directly downward, the airflow at each speed should be 
calculated based on the continuous set of sensors with the largest air 
velocity measurements. This continuous set of sensors must be along the 
axis that the ceiling fan tilt is directed in (and along the axis that 
is 180 degrees from the first axis). For example, a 42-inch fan tilted 
toward axis A may create the pattern of air velocity shown in Figure 3 
of this appendix. As shown in Table 1 of this appendix, a 42-inch fan 
would normally require 7 active sensors. However because the fan is not 
directed downward, all sensors must record data. In this case, because 
the set of sensors corresponding to maximum air velocity are centered 3 
sensor positions away from the sensor 1 along the A axis, substitute the 
air velocity at A axis sensor 4 for the average air velocity at sensor 
1. Take the average of the air velocity at A axis sensors 3 and 5 as a 
substitute for the average air velocity at sensor 2, take the average of 
the air velocity at A axis sensors 2 and 6 as a substitute for the 
average air velocity at sensor 3, etc. Lastly, take the average of the 
air velocities at A axis sensor 10 and C axis sensor 4 as a substitute 
for the average air velocity at sensor 7. Stability criteria apply after 
these substitutions. For example, air velocity stability at sensor 7 are 
determined based on the average of average air velocity at A axis sensor 
10 and C axis sensor 4 in successive measurements. Any air velocity 
measurements made along the B-D axis are not included in the calculation 
of average air velocity.

   Sec. Appendix V1 to Subpart B of Part 430--Uniform Test Method for 
Measuring the Energy Consumption of Ceiling Fan Light Kits Packaged
With Other Fluorescent Lamps (not Compact Fluorescent Lamps or General 
     Service Fluorescent Lamps), Packaged With Other SSL Lamps (not 
         Integrated LED Lamps), or With Integrated SSL Circuitry

    Note: Any representations about the energy use or efficiency of any 
ceiling fan light kit packaged with fluorescent lamps other than compact 
fluorescent lamps or general service fluorescent lamps, packaged with 
SSL products other than integrated LED lamps, or with integrated SSL 
circuitry made on or after the compliance date of any amended energy 
conservation standards must be based on testing pursuant to this 
appendix. Manufacturers may make representations based on testing in 
accordance with this appendix prior to the compliance date of any 
amended energy conservation standards, provided that such 
representations demonstrate compliance with the amended energy 
conservation standards.
    1. Scope: This appendix establishes the test requirements to measure 
the energy efficiency of all ceiling fan light kits (CFLKs) packaged 
with fluorescent lamps other than compact fluorescent lamps or general 
service fluorescent lamps, packaged with SSL products other than 
integrated LED lamps, or with integrated SSL circuitry.
    2. Definitions
    2.1. CFLK with integrated SSL circuitry means a CFLK that has SSL 
light sources, drivers, heat sinks, or intermediate circuitry (such as 
wiring between a replaceable driver and a replaceable light source) that 
are not consumer replaceable.
    2.2. Covers means materials used to diffuse or redirect light 
produced by an SSL light source in CFLKs with integrated SSL circuitry.
    2.3. Other (non-CFL and non-GSFL) fluorescent lamp means a low-
pressure mercury electric-discharge lamp in which a fluorescing coating 
transforms some of the ultraviolet energy generated by the mercury 
discharge into light, including but not limited to circline fluorescent 
lamps, and excluding any compact fluorescent lamp and any general 
service fluorescent lamp.
    2.4. Other SSL products means an integrated unit consisting of a 
light source, driver, heat sink, and intermediate circuitry that uses 
SSL technology (such as light-emitting diodes or organic light-emitting 
diodes) and is consumer replaceable in a CFLK. The term does not include 
LED lamps with ANSI-standard bases. Examples of other SSL products 
include OLED lamps, LED lamps with non-ANSI-standard bases, such as 
Zhaga interfaces, and LED light engines.
    2.5. Solid-State Lighting (SSL) means technology where light is 
emitted from a solid object--a block of semiconductor--rather than from 
a filament or plasma, as in the case of incandescent and fluorescent 
lighting. This includes inorganic light-emitting diodes (LEDs) and 
organic light-emitting diodes (OLEDs).
    3. Test Conditions and Measurements
    For any CFLK that utilizes consumer replaceable lamps, measure the 
lamp efficacy of each basic model of lamp packaged with the CFLK. For 
any CFLK only with integrated SSL circuitry, measure the luminaire 
efficacy of the CFLK. For any CFLK that includes both consumer 
replaceable lamps and integrated SSL circuitry, measure both the lamp 
efficacy of each basic model of lamp packaged with the CFLK and the 
luminaire efficacy of the CFLK with all consumer replaceable lamps 
removed. Take measurements at full light output. Do not use a 
goniophotometer. For each test, use the test procedures in the table 
below. CFLKs with integrated SSL circuitry and consumer replaceable 
covers may be measured with their covers removed but must otherwise be 
measured according to the table below.

    Note: Before February 27, 2017, any representations, including 
certifications of compliance, made with respect to the energy use or 
efficiency of medium base compact fluorescent lamps must be made in 
accordance with the results of testing pursuant either to this appendix, 
or to the applicable test requirements set forth in 10 CFR parts 429 and 
430 as they appeared in the 10 CFR parts 200 to 499 annual edition 
revised as of January 1, 2016.
    On or after February 27, 2017, any representations, including 
certifications of compliance (if required), made with respect to the 
energy use or efficiency of CFLs must be made in accordance with the 
results of testing pursuant to this appendix.
    1. Scope:
    1.1. Integrated compact fluorescent lamps.
    1.1.1. This appendix specifies the test methods required to measure 
the initial lamp efficacy, lumen maintenance at 1,000 hours, lumen 
maintenance at 40 percent of lifetime, time to failure, power factor, 
correlated color temperature (CCT), color rendering index (CRI), and 
start time of an integrated compact fluorescent lamp.
    1.1.2. This appendix describes how to conduct rapid cycle stress 
testing for integrated compact fluorescent lamps.
    1.1.3. This appendix specifies test methods required to measure 
standby mode energy consumption applicable to integrated CFLs capable of 
operation in standby mode (as defined in Sec. 430.2), such as those 
that can be controlled wirelessly.
    1.2. Non-integrated compact fluorescent lamps.
    1.2.1. This appendix specifies the test methods required to measure 
the initial lamp efficacy, lumen maintenance at 40 percent of lifetime, 
time to failure, CCT, and CRI for non-integrated compact fluorescent 
lamps.
    2. Definitions:
    2.1. Ballasted adapter means a ballast that is not permanently 
attached to a compact fluorescent lamp, has no consumer-replaceable 
components, and serves as an adapter by incorporating both a lamp socket 
and a lamp base.
    2.2. Hybrid compact fluorescent lamp means a compact fluorescent 
lamp that incorporates one or more supplemental light sources of 
different technology.
    2.3. Initial lamp efficacy means the lamp efficacy (as defined in 
Sec. 430.2) at the end of the seasoning period, as calculated pursuant 
to section 3.2.2.9 of this appendix.
    2.4. Integrated compact fluorescent lamp means an integrally 
ballasted compact fluorescent lamp that contains all components 
necessary for the starting and stable operation of the lamp, contains an 
ANSI standard base, does not include any replaceable or interchangeable 
parts, and is capable of being connected directly to a branch circuit 
through a corresponding ANSI standard lamp-holder (socket).
    2.5. Labeled wattage means the highest wattage marked on the lamp 
and/or lamp packaging.
    2.6. Lumen maintenance means the lumen output measured at a given 
time in the life of the lamp and expressed as a percentage of the 
measured initial lumen output.
    2.7. Measured initial input power means the input power to the lamp, 
measured at the end of the lamp seasoning period, and expressed in watts 
(W).
    2.8. Measured initial lumen output means the lumen output of the 
lamp measured at the end of the lamp seasoning period, expressed in 
lumens (lm).
    2.9. Non-integrated compact fluorescent lamp means a compact

    2.10. Percent variability means the result of dividing the 
difference between the maximum and minimum values by the average value 
for a contiguous set of separate time-averaged light output values 
spanning the specified time period. For a waveform of measured light 
output values, the time-averaged light output is computed over one full 
cycle of sinusoidal input voltage, as a moving average where the 
measurement interval is incremented by one sample for each successive 
measurement value.
    2.11. Power factor means the measured input power (watts) divided by 
the product of the measured RMS input voltage (volts) and the measured 
RMS input current (amps).

the application of power to the compact fluorescent lamp and the 
beginning of the start plateau.
    2.15. Time to failure means the time elapsed between first use and 
the point at which the compact fluorescent lamp (for a hybrid CFL, the 
primary light source) ceases to produce measureable lumen output.
    3. Active Mode Test Procedures
    3.1. General Instructions.
    3.1.1. In cases where there is a conflict, the language of the test 
procedure in this appendix takes precedence over any materials 
incorporated by reference.

[[Page 698]]

    3.1.2. Maintain lamp operating orientation throughout seasoning and 
testing, including storage and handling between tests.
    3.1.3. Season CFLs prior to photometric and electrical testing in 
accordance with sections 4, 5, 6.1, and 6.2.2.1 of IES LM-54-12 
(incorporated by reference, see Sec. 430.3). Season the CFL for a 
minimum of 100 hours in accordance with section 6.2.2.1 of IES LM-54-12. 
During the 100 hour seasoning period, cycle the CFL (operate the lamps 
for 180 minutes, 20 minutes off) as specified in section 6.4 of IES LM-
65-14 (incorporated by reference; see Sec. 430.3).
    3.1.3.1. Unit operating time during seasoning may be counted toward 
time to failure, lumen maintenance at 40 percent of lifetime of a 
compact fluorescent lamp (as defined in Sec. 430.2), and lumen 
maintenance at 1,000 hours if the required operating cycle and test 
conditions for time to failure testing per section 3.3.1 of this 
appendix are satisfied.
    3.1.3.2. If a lamp breaks, becomes defective, fails to stabilize, 
exhibits abnormal behavior (such as swirling), or stops producing light 
prior to the end of the seasoning period, the lamp must be replaced with 
a new unit. If a lamp exhibits one of the conditions listed in the 
previous sentence after the seasoning period, the lamp's measurements 
must be included in the sample. Record number of lamps replaced, if any.
    3.1.4. Conduct all testing with the lamp operating at labeled 
wattage. This requirement applies to all CFLs, including those that are 
dimmable or multi-level.
    3.1.5. Operate the CFL at the rated input voltage throughout 
testing. For a CFL with multiple rated input voltages including 120 
volts, operate the CFL at 120 volts. If a CFL with multiple rated input 
voltages is not rated for 120 volts, operate the CFL at the highest 
rated input voltage.
    3.1.6. Test CFLs packaged with ballasted adapters or designed 
exclusively for use with ballasted adapters as non-integrated CFLs, with 
no ballasted adapter in the circuit.
    3.1.7. Conduct all testing of hybrid CFLs with all supplemental 
light sources in the lamp turned off, if possible. Before taking 
measurements, verify that the lamp has stabilized in the operating mode 
that corresponds to its primary light source.
    3.2. Test Procedures for Determining Initial Lamp Efficacy, Lumen 
Maintenance, CCT, CRI, and Power Factor.
    Determine initial lamp efficacy, lumen maintenance at 40 percent of 
lifetime of a compact fluorescent lamp (as defined in in Sec. 430.2), 
CCT, and CRI for integrated and non-integrated CFLs. Determine lumen 
maintenance at 1,000 hours and power factor for integrated CFLs only.
    3.2.1. Test Conditions and Setup
    3.2.1.1. Test half of the units in the sample in the base up 
position, and half of the units in the base down position; if the 
position is restricted by the manufacturer, test the units in the 
manufacturer-specified position.
    3.2.1.2. Establish ambient conditions, power supply, auxiliary 
equipment, circuit setup, lamp connections, and instrumentation in 
accordance with the specifications in sections (and corresponding 
subsections) 4.0, 5.0 and 6.0 of IES LM-66-14 (incorporated by

   Sec. Appendix X to Subpart B of Part 430--Uniform Test Method for 
            Measuring the Energy Consumption of Dehumidifiers

    Note: After January 27, 2016, any representations made with respect 
to the energy use or efficiency of portable dehumidifiers must be made 
in accordance with the results of testing pursuant to this appendix.
    Until January 27, 2016, manufacturers must either test portable 
dehumidifiers in accordance with this appendix, or the previous version 
of this appendix as it appeared in the Code of Federal Regulations on 
January 1, 2015. DOE notes that, because testing under this appendix X 
must be completed as of January 27, 2016, manufacturers may wish to 
begin using this test procedure immediately.
    Alternatively, manufacturers may certify compliance with any amended 
energy conservation standards for portable dehumidifiers prior to the 
compliance date of those amended energy conservation standards by 
testing in accordance with appendix X1. Any representations made with 
respect to the energy use or efficiency of such portable dehumidifiers 
must be in accordance with whichever version is selected.

[[Page 701]]

    Any representations made on or after the compliance date of any 
amended energy conservation standards, with respect to the energy use or 
efficiency of portable or whole-home dehumidifiers, must be made in 
accordance with the results of testing pursuant to appendix X1.

                                1. Scope

    This appendix covers the test requirements used to measure the 
energy performance of dehumidifiers.

                             2. Definitions

    2.1 ANSI/AHAM DH-1 means the test standard published by the American 
National Standards Institute and the Association of Home Appliance 
Manufacturers, titled ``Dehumidifiers,'' ANSI/AHAM DH-1-2008, 
(incorporated by reference; see Sec. 430.3).
    2.2 Active mode means a mode in which a dehumidifier is connected to 
a mains power source, has been activated, and is performing the main 
functions of removing moisture from air by drawing moist air over a 
refrigerated coil using a fan, or circulating air through activation of 
the fan without activation of the refrigeration system.
    2.3 Combined low-power mode means the aggregate of available modes 
other than dehumidification mode.
    2.4 Dehumidification mode means an active mode in which a 
dehumidifier:
    (1) Has activated the main moisture removal function according to 
the humidistat, humidity sensor signal, or control setting; and
    (2) Has either activated the refrigeration system or activated the 
fan or blower without activation of the refrigeration system.
    2.5 Energy factor for dehumidifiers means a measure of energy 
efficiency of a dehumidifier calculated by dividing the water removed 
from the air by the energy consumed, measured in liters per kilowatt-
hour (L/kWh).
    2.6 IEC 62301 means the test standard published by the International 
Electrotechnical Commission, titled ``Household electrical appliances--
Measurement of standby power,'' Publication 62301 (Edition 2.0 2011-01) 
(incorporated by reference; see Sec. 430.3).
    2.7 Inactive mode means a standby mode that facilitates the 
activation of active mode by remote switch (including remote control), 
internal sensor other than humidistat or humidity sensor, or timer, or 
that provides continuous status display.
    2.8 Off mode means a mode in which the dehumidifier is connected to 
a mains power source and is not providing any active mode or standby 
mode function, and where the mode may persist for an indefinite time. An 
indicator that only shows the user that the dehumidifier is in the off 
position is included within the classification of an off mode.
    2.9 Off-cycle mode means a standby mode in which the dehumidifier:
    (1) Has cycled off its main function by humidistat or humidity 
sensor;
    (2) Does not have its fan or blower operating; and
    (3) Will reactivate the main function according to the humidistat or 
humidity sensor signal.
    2.10 Product capacity for dehumidifiers means a measure of the 
ability of the dehumidifier to remove moisture from its surrounding 
atmosphere, measured in pints collected per 24 hours of operation under 
the specified ambient conditions.
    2.11 Standby mode means any modes where the dehumidifier is 
connected to a mains power source and offers one or more of the 
following user-oriented or protective functions which may persist for an 
indefinite time:
    (1) To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch (including 
remote control), internal sensor, or timer;
    (2) Continuous functions, including information or status displays 
(including clocks) or sensor-based functions. A timer is a continuous 
clock function (which may or may not be associated with a display) that 
provides regular scheduled tasks (e.g., switching) and that operates on 
a continuous basis.

               3. Test Apparatus and General Instructions

    3.1 Active mode. The test apparatus and instructions for testing 
dehumidifiers in dehumidification mode shall conform to the requirements 
specified in Section 3, ``Definitions,'' Section 4, ``Instrumentation,'' 
and Section 5, ``Test Procedure,'' of ANSI/AHAM DH-1 (incorporated by 
reference, see Sec. 430.3), with the following exceptions.
    3.1.1 Psychrometer placement. Place the psychrometer perpendicular 
to, and 1 ft. in front of, the center of the intake grille. For 
dehumidifiers with multiple intake grilles, place a separate sampling 
tree perpendicular to, and 1 ft. in front of, the center of each intake 
grille, with the samples combined and connected to a single psychrometer 
using a minimal length of insulated ducting. The psychrometer shall be 
used to monitor inlet conditions of one test unit only.
    3.1.2 Condensate collection. If means are provided on the 
dehumidifier for draining condensate away from the cabinet, collect the 
condensate in a substantially closed vessel to prevent re-evaporation, 
and place the collection vessel on the weight-measuring instrument. If 
no means for draining condensate away from the cabinet are provided, 
disable any automatic shutoff of dehumidification mode operation that is 
activated when the collection container is full, and collect any 
overflow in a pan. The pan

[[Page 702]]

must be covered as much as possible to prevent re-evaporation without 
impeding the collection of overflow water. Place both the dehumidifier 
and the overflow pan on the weight-measuring instrument for direct 
reading of the condensate weight during the test. Do not use any 
internal pump to drain the condensate unless such pump operation is 
provided for by default in dehumidification mode.
    3.1.3 Control settings. If the dehumidifier has a control setting 
for continuous operation in dehumidification mode, select that setting. 
Otherwise, set the controls to the lowest available relative humidity 
level and, if the dehumidifier has a user-adjustable fan speed, select 
the maximum fan speed setting.
    3.1.4 Recording and rounding. Record measurements at the resolution 
of the test instrumentation. Round calculated values to the same number 
of significant digits as the previous step. Round the final capacity, 
energy factor and integrated energy factor values to two decimal places.
    3.2 Standby mode and off mode.
    3.2.1 Installation requirements. For the standby mode and off mode 
testing, the dehumidifier shall be installed in accordance with Section 
5, Paragraph 5.2 of IEC 62301 (incorporated by reference, see Sec. 
430.3), disregarding the provisions regarding batteries and the 
determination, classification, and testing of relevant modes.
    3.2.2 Electrical energy supply.
    3.2.2.1 Electrical supply. For the standby mode and off mode 
testing, maintain the electrical supply voltage and frequency indicated 
in Section 7.1.3, ``Standard Test Voltage,'' of ANSI/AHAM DH-1, 
(incorporated by reference, see Sec. 430.3). The electrical supply 
frequency shall be maintained 1 percent.
    3.2.2.2 Supply voltage waveform. For the standby mode and off mode 
testing, maintain the electrical supply voltage waveform indicated in 
Section 4, Paragraph 4.3.2 of IEC 62301, (incorporated by reference; see 
Sec. 430.3).
    3.2.3 Standby mode and off mode watt meter. The watt meter used to 
measure standby mode and off mode power consumption shall meet the 
requirements specified in Section 4, Paragraph 4.4 of IEC 62301 
(incorporated by reference, see Sec. 430.3).
    3.2.4 Standby mode and off mode ambient temperature. For standby 
mode and off mode testing, maintain room ambient air temperature 
conditions as specified in Section 4, Paragraph 4.2 of IEC 62301 
(incorporated by reference; see Sec. 430.3).

                           4. Test Measurement

    4.1 Active mode. Measure the energy consumption in dehumidification 
mode, EDM, expressed in kilowatt-hours (kWh), the energy 
factor, expressed in liters per kilowatt-hour (L/kWh), and product 
capacity, expressed in pints per day (pints/day), in accordance with the 
test requirements specified in Section 7, ``Capacity Test and Energy 
Consumption Test,'' of ANSI/AHAM DH-1 (incorporated by reference, see 
Sec. 430.3).
    4.2 Standby mode and off mode. Establish the testing conditions set 
forth in section 3.2 of this appendix, ensuring that the dehumidifier 
does not enter active mode during the test. For dehumidifiers that take 
some time to enter a stable state from a higher power state as discussed 
in Section 5, Paragraph 5.1, Note 1 of IEC 62301, (incorporated by 
reference; see Sec. 430.3), allow sufficient time for the dehumidifier 
to reach the lower power state before proceeding with the test 
measurement. Follow the test procedure specified in Section 5, Paragraph 
5.3.2 of IEC 62301 for testing in each possible mode as described in 
sections 4.2.1 and 4.2.2 of this appendix.
    4.2.1 If the dehumidifier has an inactive mode, as defined in 
section 2.7 of this appendix, but not an off mode, as defined in section 
2.8 of this appendix, measure and record the average inactive mode power 
of the dehumidifier, PIA, in watts. Otherwise, if the 
dehumidifier has an off mode, as defined in section 2.8 of this 
appendix, measure and record the average off mode power of the 
dehumidifier, POM, in watts.
    4.2.2 If the dehumidifier has an off-cycle mode, as defined in 
section 2.9 of this appendix, measure and record the average off-cycle 
mode power of the dehumidifier, POC, in watts.

        5. Calculation of Derived Results From Test Measurements

    5.1 Annual combined low-power mode energy consumption. Calculate the 
annual combined low-power mode energy consumption for dehumidifiers, 
ETLP, expressed in kilowatt-hours per year, according to the 
following:

ETLP = [(PIO x SIO) + (POC x 
          SOC)] x K

Where:

PIO = PIA, dehumidifier inactive mode power, or 
          POM, dehumidifier off mode power in watts, as 
          measured in section 4.2.1 of this appendix.
POC = dehumidifier off-cycle mode power in watts, as measured 
          in section 4.2.2 of this appendix.
SIO = 1,840.5 dehumidifier inactive mode or off mode annual 
          hours.
SOC = 1,840.5 dehumidifier off-cycle mode annual hours.
K = 0.001 kWh/Wh conversion factor for watt-hours to kilowatt-hours.

    5.2 Integrated energy factor. Calculate the integrated energy 
factor, IEF, expressed in liters per kilowatt-hour, rounded to two 
decimal places, according to the following:

IEF = LW/[EDM + ((ETLP/1095) x 6)]

Where:


[[Page 703]]


LW = water removed from the air during the 6-hour 
          dehumidification mode test in liters, as measured in section 
          4.1 of this appendix.
EDM = energy consumption during the 6-hour dehumidification 
          mode test in kilowatt-hours, as measured in section 4.1 of 
          this appendix.
ETLP = annual combined low-power mode energy consumption in 
          kilowatt-hours per year, as calculated in section 5.1 of this 
          appendix.
1,095 = dehumidification mode annual hours, used to convert 
          ETLP to combined low-power mode energy consumption 
          per hour of dehumidification mode.
6 = hours per dehumidification mode test, used to convert combined low-
          power mode energy consumption per hour of dehumidification 
          mode for integration with dehumidification mode energy 
          consumption.

    2.16 Reactivation air means the air drawn from unconditioned space 
to remove moisture from the desiccant wheel of a refrigerant-desiccant 
dehumidifier and discharged to unconditioned space.
    2.17 Standby mode means any modes where the dehumidifier is 
connected to a mains power source and offers one or more of the 
following user-oriented or protective functions which may persist for an 
indefinite time:
    (1) To facilitate the activation of other modes (including 
activation or deactivation of active mode) by remote switch (including 
remote control), internal sensor, or timer;
    (2) Continuous functions, including information or status displays 
(including clocks) or sensor-based functions. A timer is a continuous 
clock function (which may or may not be associated with a display) that 
provides regular scheduled tasks (e.g., switching) and that operates on 
a continuous basis.

               3. Test Apparatus and General Instructions

    3.1 Active mode.
    3.1.1 Portable dehumidifiers and whole-home dehumidifiers other than 
refrigerant-desiccant dehumidifiers. The test apparatus and instructions 
for testing in dehumidification mode and off-cycle mode must conform to 
the requirements specified in Section 3, ``Definitions,'' Section 4, 
``Instrumentation,'' and Section 5, ``Test Procedure,'' of ANSI/AHAM DH-
1 (incorporated by reference, see Sec. 430.3), with the following 
exceptions. Note that if a product is able to operate as both a portable 
and whole-home dehumidifier by means of installation or removal of an 
optional ducting kit, it must be tested and rated for both 
configurations.
    3.1.1.1 Testing configuration for whole-home dehumidifiers other 
than refrigerant-desiccant dehumidifiers. Test dehumidifiers, other than 
refrigerant-desiccant dehumidifiers, with ducting attached to the 
process air outlet port. The duct configuration and component placement 
must conform to the requirements specified in section 3.1.3 of this 
appendix and Figure 1 or Figure 3, except that the flow straightener and 
dry-bulb temperature and relative humidity instruments are not required. 
Maintain the external static pressure in the process air flow and 
measure the external static pressure as specified in section 3.1.2.2.3.1 
of this appendix.
    3.1.1.2 Relative humidity instrumentation. A relative humidity 
sensor with an accuracy within 1 percent relative humidity may be used 
in place of an aspirating psychrometer. When using a relative humidity 
sensor for testing, disregard the wet-bulb test tolerances in Table 1 of 
ANSI/AHAM DH-1 (incorporated by reference, see Sec. 430.3), the average 
relative humidity over the test period must be within 2 percent of the 
relative humidity setpoint, and all individual relative humidity 
readings must be within 5 percent of the relative humidity setpoint. 
When using a relative humidity sensor instead of an aspirating 
psychrometer, use a dry-bulb temperature sensor that meets the accuracy 
as required in section 4.1 of ANSI/AHAM DH-1.
    3.1.1.3 Instrumentation placement. Place the aspirating psychrometer 
or relative humidity and dry-bulb temperature sensors perpendicular to, 
and 1 ft. in front of, the center of the process air intake grille. When 
using an aspirating psychrometer, for dehumidifiers with multiple 
process air intake grilles, place a separate sampling tree perpendicular 
to, and 1 ft. in front of, the center of each process air intake grille, 
with the samples combined and connected to a single psychrometer using a 
minimal length of insulated ducting. The psychrometer shall be used to 
monitor inlet conditions of one test unit only. When using relative 
humidity and dry-bulb temperature sensors, for dehumidifiers with 
multiple process air intake grilles, place a relative humidity sensor 
and dry-bulb temperature sensor perpendicular to, and 1 ft. in front of, 
the center of each process air intake grille.
    3.1.1.4 Condensate collection. If means are provided on the 
dehumidifier for draining condensate away from the cabinet, collect the 
condensate in a substantially closed vessel to prevent re-evaporation 
and place the vessel on the weight-measuring instrument. If no means for 
draining condensate away from the cabinet are provided, disable any 
automatic shutoff of dehumidification mode operation that is activated 
when the collection container is full and collect any overflow in a pan. 
Select a collection pan large enough to ensure that all water that 
overflows from the full internal collection container during the rating 
test period is captured by the collection pan. Cover the pan as much as 
possible to prevent re-evaporation without impeding the collection of 
overflow water. Place both the dehumidifier and the

[[Page 705]]

overflow pan on the weight-measuring instrument for direct reading of 
the condensate weight collected during the rating test. Do not use any 
internal pump to drain the condensate into a substantially closed vessel 
unless such pump operation is provided for by default in 
dehumidification mode.
    3.1.1.5 Control settings. If the dehumidifier has a control setting 
for continuous operation in dehumidification mode, select that control 
setting. Otherwise, set the controls to the lowest available relative 
humidity level, and if the dehumidifier has a user-adjustable fan speed, 
select the maximum fan speed setting. Do not use any external controls 
for the dehumidifier settings.
    3.1.1.6 Run-in period. Perform a single run-in period during which 
the compressor operates for a cumulative total of at least 24 hours 
prior to dehumidification mode testing.
    3.1.2 Refrigerant-desiccant dehumidifiers. The test apparatus and 
instructions for testing refrigerant-desiccant dehumidifiers in 
dehumidification mode must conform to the requirements specified in 
Section 3, ``Definitions,'' Section 4, ``Instrumentation,'' and Section 
5, ``Test Procedure,'' of ANSI/AHAM DH-1 (incorporated by reference, see 
Sec. 430.3), except as follows.
    3.1.2.1 Testing configuration. Test refrigerant-desiccant 
dehumidifiers with ducting attached to the process air inlet and outlet 
ports and the reactivation air inlet port. The duct configuration and 
components must conform to the requirements specified in section 3.1.3 
of this appendix and Figure 1 through Figure 3. Install a cell-type 
airflow straightener that conforms to the specifications in Section 
5.2.1.6, ``Airflow straightener'', and Figure 6A, ``Flow Straightener--
Cell Type'', of ANSI/AMCA 210 (incorporated by reference, see Sec. 
430.3) in each duct consistent with Figure 1 through Figure 3.
    3.1.2.2 Instrumentation.
    3.1.2.2.1 Temperature. Install dry-bulb temperature sensors in a 
grid centered in the duct, with the plane of the grid perpendicular to 
the axis of the duct. Determine the number and locations of the sensors 
within the grid according to Section 5.3.5, ``Centers of Segments--
Grids,'' of ANSI/ASHRAE 41.1 (incorporated by reference, see Sec. 
430.3).
    3.1.2.2.2 Relative humidity. Measure relative humidity with a duct-
mounted, relative humidity sensor with an accuracy within 1 percent relative humidity. Place the relative humidity 
sensor at the duct centerline within 1 inch of the dry-bulb temperature 
grid plane.
    3.1.2.2.3 Pressure. The pressure instruments used to measure the 
external static pressure and velocity pressures must have an accuracy 
within 0.01 in. w.c. and a resolution of no more 
than 0.01 in. w.c.
    3.1.2.2.3.1 External static pressure. Measure static pressures in 
each duct using pitot-static tube traverses that conform with the 
specifications in Section 4.3.1, ``Pitot Traverse,'' of ANSI/AMCA 210 
(incorporated by reference, see Sec. 430.3), with pitot-static tubes 
that conform with the specifications in Section 4.2.2, ``Pitot-Static 
Tube,'' of ANSI/AMCA, except that only two intersecting and 
perpendicular rows of pitot-static tube traverses shall be used. Record 
the static pressure within the test duct as measured at the pressure tap 
in the manifold of the traverses that averages the individual static 
pressures at each pitot-static tube. Calculate duct pressure losses 
between the unit under test and the plane of each static pressure 
measurement in accordance with section 7.5.2, ``Pressure Losses,'' of 
ANSI/AMCA 210. The external static pressure is the difference between 
the measured inlet and outlet static pressure measurements, minus the 
sum of the inlet and outlet duct pressure losses. For any port with no 
duct attached, use a static pressure of 0.00 in. w.c. with no duct 
pressure loss in the calculation of external static pressure. During 
dehumidification mode testing, the external static pressure must equal 
0.20 in. w.c.  0.02 in. w.c.
    3.1.2.2.3.2 Velocity pressure. Measure velocity pressures using the 
same pitot traverses as used for measuring external static pressure, and 
which are specified in section 3.1.2.2.3.1 of this appendix. Determine 
velocity pressures at each pitot-static tube in a traverse as the 
difference between the pressure at the impact pressure tap and the 
pressure at the static pressure tap. Calculate volumetric flow rates in 
each duct in accordance with Section 7.3.1, ``Velocity Traverse,'' of 
ANSI/AMCA 210 (incorporated by reference, see Sec. 430.3).
    3.1.2.2.4 Weight. No weight-measuring instruments are required.
    3.1.2.3 Control settings. If the dehumidifier has a control setting 
for continuous operation in dehumidification mode, select that control 
setting. Otherwise, set the controls to the lowest available relative 
humidity level, and if the dehumidifier has a user-adjustable fan speed, 
select the maximum fan speed setting. Do not use any external controls 
for the dehumidifier settings.
    3.1.2.4 Run-in period. Perform a single run-in period during which 
the compressor operates for a cumulative total of at least 24 hours 
prior to dehumidification mode testing.
    3.1.3 Ducting for whole-home dehumidifiers. Cover and seal with tape 
any port designed for intake of air from outside or unconditioned space, 
other than for supplying reactivation air for refrigerant-desiccant 
dehumidifiers. Use only ducting constructed of galvanized mild steel and 
with a 10-inch diameter. Position inlet and outlet

[[Page 706]]

ducts either horizontally or vertically to accommodate the default 
dehumidifier port orientation. Install all ducts with the axis of the 
section interfacing with the dehumidifier perpendicular to plane of the 
collar to which each is attached. If manufacturer-recommended collars do 
not measure 10 inches in diameter, use transitional pieces to connect 
the ducts to the collars. The transitional pieces must not contain any 
converging element that forms an angle with the duct axis greater than 
7.5 degrees or a diverging element that forms an angle with the duct 
axis greater than 3.5 degrees. Install mechanical throttling devices in 
each outlet duct consistent with Figure 1 and Figure 3 to adjust the 
external static pressure and in the inlet reactivation air duct for a 
refrigerant-desiccant dehumidifier. Cover the ducts with thermal 
insulation having a minimum R value of 6 h-ft\2\ - [deg]F/Btu (1.1 m\2\ 
- K/W). Seal seams and edges with tape.

    3.1.4 Recording and rounding. When testing either a portable 
dehumidifier or a whole-home dehumidifier, record measurements at the 
resolution of the test instrumentation. Record measurements for portable 
dehumidifiers and whole-home dehumidifiers other than refrigerant-
desiccant dehumidifiers at intervals no greater than 10 minutes. Record 
measurements for refrigerant-desiccant dehumidifiers at intervals no 
greater than 1 minute. Round off calculations to the same number of 
significant digits as the previous step. Round the final product 
capacity, energy factor and integrated energy factor values to two 
decimal places, and for whole-home dehumidifiers, round the final 
product case volume to one decimal place.
    3.2 Inactive mode and off mode.
    3.2.1 Installation requirements. For the inactive mode and off mode 
testing, install the dehumidifier in accordance with Section 5, 
Paragraph 5.2 of IEC 62301 (incorporated by reference, see Sec. 430.3), 
disregarding the provisions regarding batteries and the determination, 
classification, and testing of relevant modes.
    3.2.2 Electrical energy supply.

[[Page 709]]

    3.2.2.1 Electrical supply. For the inactive mode and off mode 
testing, maintain the electrical supply voltage and frequency indicated 
in Section 7.1.3, ``Standard Test Voltage,'' of ANSI/AHAM DH-1 
(incorporated by reference, see Sec. 430.3). The electrical supply 
frequency shall be maintained 1 percent.
    3.2.2.2 Supply voltage waveform. For the inactive mode and off mode 
testing, maintain the electrical supply voltage waveform indicated in 
Section 4, Paragraph 4.3.2 of IEC 62301 (incorporated by reference, see 
Sec. 430.3).
    3.2.3 Inactive mode, off mode, and off-cycle mode wattmeter. The 
wattmeter used to measure inactive mode, off mode, and off-cycle mode 
power consumption must meet the requirements specified in Section 4, 
Paragraph 4.4 of IEC 62301 (incorporated by reference, see Sec. 430.3).
    3.2.4 Inactive mode and off mode ambient temperature. For inactive 
mode and off mode testing, maintain room ambient air temperature 
conditions as specified in Section 4, Paragraph 4.2 of IEC 62301 
(incorporated by reference, see Sec. 430.3).
    3.3 Case dimensions for whole-home dehumidifiers. Measure case 
dimensions using equipment with a resolution of no more than 0.1 in.

                           4. Test Measurement

    4.1 Dehumidification mode.
    4.1.1 Portable dehumidifiers and whole-home dehumidifiers other than 
refrigerant-desiccant dehumidifiers. Measure the energy consumption in 
dehumidification mode, EDM, expressed in kilowatt-hours 
(kWh), the average relative humidity, Ht, either as measured 
using a relative humidity sensor or using the tables provided below when 
using an aspirating psychrometer, and the product capacity, 
Ct, expressed in pints per day (pints/day), in accordance 
with the test requirements specified in Section 7, ``Capacity Test and 
Energy Consumption Test,'' of ANSI/AHAM DH-1 (incorporated by reference, 
see Sec. 430.3), except that the standard test conditions for portable 
dehumidifiers must be maintained at 65 [deg]F  2.0 
[deg]F dry-bulb temperature and 56.6 [deg]F  1.0 
[deg]F wet-bulb temperature, when recording conditions with an 
aspirating psychrometer, or 60 percent  2 percent 
relative humidity, when recording conditions with a relative humidity 
sensor. For whole-home dehumidifiers, conditions must be maintained at 
73 [deg]F  2.0 [deg]F dry-bulb temperature and 
63.6 [deg]F  1.0 [deg]F wet-bulb temperature, when 
recording conditions with an aspirating psychrometer, or 60 percent 
 2 percent relative humidity, when recording 
conditions with a relative humidity sensor. When using relative humidity 
and dry-bulb temperature sensors, for dehumidifiers with multiple 
process air intake grilles, average the measured relative humidities and 
average the measured dry-bulb temperatures to determine the overall 
intake air conditions.

    4.1.2 Refrigerant-desiccant dehumidifiers. Establish the testing 
conditions set forth in section 3.1.2 of this appendix. Measure the 
energy consumption, EDM, expressed in kWh,

[[Page 710]]

in accordance with the test requirements specified in Section 7, 
``Capacity Test and Energy Consumption Test,'' of ANSI/AHAM DH-1 
(incorporated by reference, see Sec. 430.3), except that: (1) 
individual readings of the standard test conditions at the air entering 
the process air inlet duct and the reactivation air inlet must be 
maintained within 73 [deg]F  2.0 [deg]F dry-bulb 
temperature and 60 percent  5 percent relative 
humidity and the arithmetic average of the inlet test conditions over 
the test period shall be maintained within 73 [deg]F  0.5 [deg]F dry-bulb temperature and 60 percent  2 percent relative humidity; (2) the instructions for 
psychrometer placement do not apply; (3) the data recorded must include 
dry-bulb temperatures, relative humidities, static pressures, velocity 
pressures in each duct, volumetric air flow rates, and the number of 
samples in the test period; (4) the condensate collected during the test 
need not be weighed; and (5) the calculations in Section 7.2.2, ``Energy 
Factor Calculation,'' of ANSI/AHAM DH-1 need not be performed. To 
perform the calculations in Section 7.1.7, ``Calculation of Test 
Results,'' of ANSI/AHAM DH-1: (1) replace ``Condensate collected (lb)'' 
and ``mlb'', with the weight of condensate removed, W, as 
calculated in section 5.6 of this appendix; and (2) use the recorded 
relative humidities rather than the tables in section 4.1.1 of this 
appendix to determine average relative humidity.
    4.2 Off-cycle mode. Establish the test conditions specified in 
section 3.1.1 or 3.1.2 of this appendix, but use the wattmeter specified 
in section 3.2.3 of this appendix. Begin the off-cycle mode test period 
immediately following the dehumidification mode test period. Adjust the 
setpoint higher than the ambient relative humidity to ensure the product 
will not enter dehumidification mode and begin the test when the 
compressor cycles off due to the change in setpoint. The off-cycle mode 
test period shall be 2 hours in duration, during which the power 
consumption is recorded at the same intervals as recorded for 
dehumidification mode testing. Measure and record the average off-cycle 
mode power of the dehumidifier, POC, in watts.
    4.3 Inactive and off mode. Establish the testing conditions set 
forth in section 3.2 of this appendix, ensuring that the dehumidifier 
does not enter active mode during the test. For dehumidifiers that take 
some time to enter a stable state from a higher power state, as 
discussed in Section 5, Paragraph 5.1, Note 1 of IEC 62301 (incorporated 
by reference; see Sec. 430.3), allow sufficient time for the 
dehumidifier to reach the lower power state before proceeding with the 
test measurement. Follow the test procedure specified in Section 5, 
Paragraph 5.3.2 of IEC 62301 for testing in each possible mode as 
described in sections 4.3.1 and 4.3.2 of this appendix.
    4.3.1 If the dehumidifier has an inactive mode, as defined in 
section 2.10 of this appendix, but not an off mode, as defined in 
section 2.11 of this appendix, measure and record the average inactive 
mode power of the dehumidifier, PIA, in watts.
    4.3.2 If the dehumidifier has an off mode, as defined in section 
2.11 of this appendix, measure and record the average off mode power of 
the dehumidifier, POM, in watts.
    4.4 Product case volume for whole-home dehumidifiers. Measure the 
maximum case length, DL, in inches, the maximum case width, 
DW, in inches, and the maximum height, DH, in 
inches, exclusive of any duct collar attachments or other external 
components.

        5. Calculation of Derived Results From Test Measurements

    5.1 Corrected relative humidity. Calculate the average relative 
humidity, for portable and whole-home dehumidifiers, corrected for 
barometric pressure variations as:

Hc,p = Ht x [1 + 0.0083 x (29.921 - B)]
Hc,wh = Ht x [1 + 0.0072 x (29.921 - B)]

Where:

Hc,p = portable dehumidifier average relative humidity from 
          the test data in percent, corrected to the standard barometric 
          pressure of 29.921 in. mercury (Hg);
Hc,wh = whole-home dehumidifier average relative humidity 
          from the test data in percent, corrected to the standard 
          barometric pressure of 29.921 in. Hg;
Ht = average relative humidity from the test data in percent; 
          and
B = average barometric pressure during the test period in in. Hg.

    5.2 Corrected product capacity. Calculate the product capacity, for 
portable and whole-home dehumidifiers, corrected for variations in 
temperature and relative humidity as:

Cr,p = Ct + 0.0352 x Ct x (65 - 
          Tt) + 0.0169 x Ct x (60 - 
          HC,p)
Cr,wh = Ct + 0.0344 x Ct x (73 - 
          Tt) + 0.017 x Ct x (60 - 
          HC,wh)

Where:

Cr,p = portable dehumidifiers product capacity in pints/day,

   Sec. Appendix Y to Subpart B of Part 430--Uniform Test Method for 
          Measuring the Energy Consumption of Battery Chargers

    Prior to November 16, 2016, manufacturers must make any 
representations regarding the energy consumption of battery chargers 
other than uninterruptible power supplies based upon results generated 
under this appendix or the previous version of this appendix as it 
appeared in the Code of Federal Regulations on January 1, 2016. On or 
after November 16, 2016, manufacturers must make any representations 
regarding the energy

[[Page 714]]

consumption of battery chargers other than uninterruptible power 
supplies based upon results generated under this appendix. On or after 
June 12, 2017, manufacturers must make any representations regarding the 
energy efficiency of uninterruptible power supplies based upon results 
generated under this appendix.

                                1. Scope

    This appendix provides the test requirements used to measure the 
energy consumption of battery chargers operating at either DC or United 
States AC line voltage (115V at 60Hz). This appendix also provides the 
test requirements used to measure the energy efficiency of 
uninterruptible power supplies as defined in section 2 of this appendix 
that utilize the standardized National Electrical Manufacturer 
Association (NEMA) plug, 1-15P or 5-15P, as specified in ANSI/NEMA WD 6-
2016 (incorporated by reference, see Sec. 430.3) and have an AC output. 
This appendix does not provide a method for testing back-up battery 
chargers.

                             2. Definitions

    The following definitions are for the purposes of explaining the 
terminology associated with the test method for measuring battery 
charger energy consumption.\1\
---------------------------------------------------------------------------

    \1\ For clarity on any other terminology used in the test method, 
please refer to IEEE Standard 1515-2000.
---------------------------------------------------------------------------

    2.1. Active mode or charge mode is the state in which the battery 
charger system is connected to the main electricity supply, and the 
battery charger is delivering current, equalizing the cells, and 
performing other one-time or limited-time functions in order to bring 
the battery to a fully charged state.
    2.2. Active power or real power (P) means the average power consumed 
by a unit. For a two terminal device with current and voltage waveforms 
i(t) and v(t), which are periodic with period T, the real or active 
power P is:
[GRAPHIC] [TIFF OMITTED] TR01JN11.020

    2.3. Ambient temperature is the temperature of the ambient air 
immediately surrounding the unit under test.
    2.4. Apparent power (S) is the product of root-mean-square (RMS) 
voltage and RMS current in volt-amperes (VA).
    2.5. Batch charger is a battery charger that charges two or more 
identical batteries simultaneously in a series, parallel, series-
parallel, or parallel-series configuration. A batch charger does not 
have separate voltage or current regulation, nor does it have any 
separate indicators for each battery in the batch. When testing a batch 
charger, the term ``battery'' is understood to mean, collectively, all 
the batteries in the batch that are charged together. A charger can be 
both a batch charger and a multi-port charger or multi-voltage charger.
    2.6. Battery or battery pack is an assembly of one or more 
rechargeable cells and any integral protective circuitry intended to 
provide electrical energy to a consumer product, and may be in one of 
the following forms: (a) Detachable battery (a battery that is contained 
in a separate enclosure from the consumer product and is intended to be 
removed or disconnected from the consumer product for recharging); or 
(b) integral battery (a battery that is contained within the consumer 
product and is not removed from the consumer product for charging 
purposes). The word ``intended'' in this context refers to the whether a 
battery has been designed in such a way as to permit its removal or 
disconnection from its associated consumer product.
    2.7. Battery energy is the energy, in watt-hours, delivered by the 
battery under the specified discharge conditions in the test procedure.
    2.8. Battery maintenance mode or maintenance mode is the mode of 
operation when the battery charger is connected to the main electricity 
supply and the battery is fully charged, but is still connected to the 
charger.
    2.9. Battery rest period is a period of time between discharge and 
charge or between charge and discharge, during which the battery is 
resting in an open-circuit state in ambient air.
    2.10. C-Rate (C) is the rate of charge or discharge, calculated by 
dividing the charge or discharge current by the nameplate battery charge 
capacity of the battery.
    2.11. Cradle is an electrical interface between an integral battery 
product and the rest of the battery charger designed to hold the product 
between uses.
    2.12. Energy storage system is a system consisting of single or 
multiple devices designed to provide power to the UPS inverter 
circuitry.
    2.13. Equalization is a process whereby a battery is overcharged, 
beyond what would be considered ``normal'' charge return, so that cells 
can be balanced, electrolyte mixed, and plate sulfation removed.
    2.14. Instructions or manufacturer's instructions means the 
documentation packaged with a product in printed or electronic form and 
any information about the product listed on a Web site maintained by the 
manufacturer and accessible by the general public at the time of the 
test. It also includes any information on the packaging or on the 
product itself. ``Instructions'' also includes any

[[Page 715]]

service manuals or data sheets that the manufacturer offers to 
independent service technicians, whether printed or in electronic form.
    2.15. Measured charge capacity of a battery is the product of the 
discharge current in amperes and the time in decimal hours required to 
reach the specified end-of-discharge voltage.
    2.16. Manual on-off switch is a switch activated by the user to 
control power reaching the battery charger. This term does not apply to 
any mechanical, optical, or electronic switches that automatically 
disconnect mains power from the battery charger when a battery is 
removed from a cradle or charging base, or for products with non-
detachable batteries that control power to the product itself.
    2.17. Multi-port charger means a battery charger that charges two or 
more batteries (which may be identical or different) simultaneously. The 
batteries are not connected in series or in parallel but with each port 
having separate voltage and/or current regulation. If the charger has 
status indicators, each port has its own indicator(s). A charger can be 
both a batch charger and a multi-port charger if it is capable of 
charging two or more batches of batteries simultaneously and each batch 
has separate regulation and/or indicator(s).
    2.18. Multi-voltage charger is a battery charger that, by design, 
can charge a variety of batteries (or batches of batteries, if also a 
batch charger) that are of different nameplate battery voltages. A 
multi-voltage charger can also be a multi-port charger if it can charge 
two or more batteries simultaneously with independent voltages and/or 
current regulation.
    2.19. Normal mode is a mode of operation for a UPS in which:
    (1) The AC input supply is within required tolerances and supplies 
the UPS,
    (2) The energy storage system is being maintained at full charge or 
is under recharge, and
    (3) The load connected to the UPS is within the UPS's specified 
power rating.
    2.20. Off mode is the condition, applicable only to units with 
manual on-off switches, in which the battery charger:
    (1) Is connected to the main electricity supply;
    (2) Is not connected to the battery; and
    (3) All manual on-off switches are turned off.
    2.21. Nameplate battery voltage is specified by the battery 
manufacturer and typically printed on the label of the battery itself. 
If there are multiple batteries that are connected in series, the 
nameplate battery voltage of the batteries is the total voltage of the 
series configuration--that is, the nameplate voltage of each battery 
multiplied by the number of batteries connected in series. Connecting 
multiple batteries in parallel does not affect the nameplate battery 
voltage.
    2.22. Nameplate battery charge capacity is the capacity, claimed by 
the battery manufacturer on a label or in instructions, that the battery 
can store, usually given in ampere-hours (Ah) or milliampere-hours (mAh) 
and typically printed on the label of the battery itself. If there are 
multiple batteries that are connected in parallel, the nameplate battery 
charge capacity of the batteries is the total charge capacity of the 
parallel configuration, that is, the nameplate charge capacity of each 
battery multiplied by the number of batteries connected in parallel. 
Connecting multiple batteries in series does not affect the nameplate 
charge capacity.
    2.23. Nameplate battery energy capacity means the product (in watts-
hours (Wh)) of the nameplate battery voltage and the nameplate battery 
charge capacity.
    2.24. Reference test load is a load or a condition with a power 
factor of greater than 0.99 in which the AC output socket of the UPS 
delivers the active power (W) for which the UPS is rated.
    2.25. Standby mode or no-battery mode means the condition in which:
    (1) The battery charger is connected to the main electricity supply;
    (2) The battery is not connected to the charger; and
    (3) For battery chargers with manual on-off switches, all such 
switches are turned on.
    2.26. Total harmonic distortion (THD), expressed as a percent, is 
the root mean square (RMS) value of an AC signal after the fundamental 
component is removed and interharmonic components are ignored, divided 
by the RMS value of the fundamental component.
    2.27. Uninterruptible power supply or UPS means a battery charger 
consisting of a combination of convertors, switches and energy storage 
devices (such as batteries), constituting a power system for maintaining 
continuity of load power in case of input power failure.
    2.27.1. Voltage and frequency dependent UPS or VFD UPS means a UPS 
that produces an AC output where the output voltage and frequency are 
dependent on the input voltage and frequency. This UPS architecture does 
not provide corrective functions like those in voltage independent and 
voltage and frequency independent systems.
    Note to 2.27.1: VFD input dependency may be verified by performing 
the AC input failure test in section 6.2.2.7 of IEC 62040-3 Ed. 2.0 
(incorporated by reference, see Sec. 430.3) and observing that, at a 
minimum, the UPS switches from normal mode of operation to battery power 
while the input is interrupted.
    2.27.2. Voltage and frequency independent UPS or VFI UPS means a UPS 
where the device remains in normal mode producing an

[[Page 716]]

AC output voltage and frequency that is independent of input voltage and 
frequency variations and protects the load against adverse effects from 
such variations without depleting the stored energy source.
    Note to 2.27.2: VFI input dependency may be verified by performing 
the steady state input voltage tolerance test and the input frequency 
tolerance test in sections 6.4.1.1 and 6.4.1.2 of IEC 62040-3 Ed. 2.0 
(incorporated by reference, see Sec. 430.3) respectively and observing 
that, at a minimum, the UPS produces an output voltage and frequency 
within the specified output range when the input voltage is varied by 
10% of the rated input voltage and the input 
frequency is varied by 2% of the rated input 
frequency.
    2.27.3. Voltage independent UPS or VI UPS means a UPS that produces 
an AC output within a specific tolerance band that is independent of 
under-voltage or over-voltage variations in the input voltage without 
depleting the stored energy source. The output frequency of a VI UPS is 
dependent on the input frequency, similar to a voltage and frequency 
dependent system.
    Note to 2.27.3: VI input dependency may be verified by performing 
the steady state input voltage tolerance test in section 6.4.1.1 of IEC 
62040-3 Ed. 2.0 (incorporated by reference, see Sec. 430.3) and 
ensuring that the UPS remains in normal mode with the output voltage 
within the specified output range when the input voltage is varied by 
10% of the rated input voltage.
    2.28. Unit under test (UUT) in this appendix refers to the 
combination of the battery charger and battery being tested.

     3.1.2. Verifying Accuracy and Precision of Measuring Equipment

    Any power measurement equipment utilized for testing must conform to 
the uncertainty and resolution requirements outlined in section 4, 
``General conditions for measurement'', as well as annexes B, ``Notes on 
the measurement of low power modes'', and D, ``Determination of 
uncertainty of measurement'', of IEC 62301 (incorporated by reference, 
see Sec. 430.3).

                     3.1.3. Setting Up the Test Room

    All tests, battery conditioning, and battery rest periods shall be 
carried out in a room with an air speed immediately surrounding the UUT 
of <=0.5 m/s. The ambient temperature shall be maintained at 20 [deg]C 
 5 [deg]C throughout the test. There shall be no 
intentional cooling of the UUT such as by use of separately powered 
fans, air conditioners, or heat sinks. The UUT shall be conditioned, 
rested, and tested on a thermally non-conductive surface. When not 
undergoing active testing, batteries shall be stored at 20 [deg]C  5 [deg]C.

      3.1.4. Verifying the UUT's Input Voltage and Input Frequency

    (a) If the UUT is intended for operation on AC line-voltage input in 
the United States, it shall be tested at 115 V at 60 Hz. If the UUT is 
intended for operation on AC line-voltage input but cannot be operated 
at 115 V at 60 Hz, it shall not be tested.
    (b) If a charger is powered by a low-voltage DC or AC input, and the 
manufacturer packages the charger with a wall adapter, sells, or 
recommends an optional wall adapter capable of providing that low 
voltage input, then the charger shall be tested using that wall adapter 
and the input reference source shall be 115 V at 60 Hz. If the wall 
adapter cannot be operated with AC input voltage at 115 V at 60 Hz, the 
charger shall not be tested.
    (c) If the UUT is designed for operation only on DC input voltage 
and the provisions of section 3.1.4(b) of this appendix do not apply, it 
shall be tested with one of the following input voltages: 5.0 V DC for 
products drawing power from a computer USB port or the midpoint of the 
rated input voltage range for all other products. The input voltage 
shall be within 1 percent of the above specified 
voltage.

[[Page 717]]

    (d) If the input voltage is AC, the input frequency shall be within 
1 percent of the specified frequency. The THD of 
the input voltage shall be <=2 percent, up to and including the 13th 
harmonic. The crest factor of the input voltage shall be between 1.34 
and 1.49.
    (e) If the input voltage is DC, the AC ripple voltage (RMS) shall 
be:
    (1) <=0.2 V for DC voltages up to 10 V; or
    (2) <=2 percent of the DC voltage for DC voltages over 10 V.

                 3.2. Unit Under Test Setup Requirements

                          3.2.1. General Setup

    (a) The battery charger system shall be prepared and set up in 
accordance with the manufacturer's instructions, except where those 
instructions conflict with the requirements of this test procedure. If 
no instructions are given, then factory or ``default'' settings shall be 
used, or where there are no indications of such settings, the UUT shall 
be tested in the condition as it would be supplied to an end user.
    (b) If the battery charger has user controls to select from two or 
more charge rates (such as regular or fast charge) or different charge 
currents, the test shall be conducted at the fastest charge rate that is 
recommended by the manufacturer for everyday use, or, failing any 
explicit recommendation, the factory-default charge rate. If the charger 
has user controls for selecting special charge cycles that are 
recommended only for occasional use to preserve battery health, such as 
equalization charge, removing memory, or battery conditioning, these 
modes are not required to be tested. The settings of the controls shall 
be listed in the report for each test.

          3.2.2. Selection and Treatment of the Battery Charger

    The UUT, including the battery charger and its associated battery, 
shall be new products of the type and condition that would be sold to a 
customer. If the battery is lead-acid chemistry and the battery is to be 
stored for more than 24 hours between its initial acquisition and 
testing, the battery shall be charged before such storage.

            3.2.3. Selection of Batteries To Use for Testing

    (a) For chargers with integral batteries, the battery packaged with 
the charger shall be used for testing. For chargers with detachable 
batteries, the battery or batteries to be used for testing will vary 
depending on whether there are any batteries packaged with the battery 
charger.
    (1) If batteries are packaged with the charger, batteries for 
testing shall be selected from the batteries packaged with the battery 
charger, according to the procedure in section 3.2.3(b) of this 
appendix.
    (2) If no batteries are packaged with the charger, but the 
instructions specify or recommend batteries for use with the charger, 
batteries for testing shall be selected from those recommended or 
specified in the instructions, according to the procedure in section 
3.2.3(b) of this appendix.
    (3) If no batteries are packaged with the charger and the 
instructions do not specify or recommend batteries for use with the 
charger, batteries for testing shall be selected from any that are 
suitable for use with the charger, according to the procedure in section 
3.2.3(b) of this appendix.
    (b)(1) From the detachable batteries specified above, use Table 
3.2.1 of this appendix to select the batteries to be used for testing, 
depending on the type of battery charger being tested. The battery 
charger types represented by the rows in the table are mutually 
exclusive. Find the single applicable row for the UUT, and test 
according to those requirements. Select only the single battery 
configuration specified for the battery charger type in Table 3.2.1 of 
this appendix.
    (2) If the battery selection criteria specified in Table 3.2.1 of 
this appendix results in two or more batteries or configurations of 
batteries of different chemistries, but with equal voltage and capacity 
ratings, determine the maintenance mode power, as specified in section 
3.3.9 of this appendix, for each of the batteries or configurations of 
batteries, and select for testing the battery or configuration of 
batteries with the highest maintenance mode power.
    (c) A charger is considered as:
    (1) Single-capacity if all associated batteries have the same 
nameplate battery charge capacity (see definition) and, if it is a batch 
charger, all configurations of the batteries have the same nameplate 
battery charge capacity.
    (2) Multi-capacity if there are associated batteries or 
configurations of batteries that have different nameplate battery charge 
capacities.
    (d) The selected battery or batteries will be referred to as the 
``test battery'' and will be used through the remainder of this test 
procedure.

----------------------------------------------------------------------------------------------------------------

           3.2.4. Limiting Other Non-Battery-Charger Functions

    (a) If the battery charger or product containing the battery charger 
does not have any additional functions unrelated to battery charging, 
this subsection may be skipped.
    (b) Any optional functions controlled by the user and not associated 
with the battery charging process (e.g., the answering machine in a 
cordless telephone charging base) shall be switched off. If it is not 
possible to switch such functions off, they shall be set to their lowest 
power-consuming mode during the test.
    (c) If the battery charger takes any physically separate connectors 
or cables not required for battery charging but associated with its 
other functionality (such as phone lines, serial or USB connections, 
Ethernet, cable TV lines, etc.), these connectors or cables shall be 
left disconnected during the testing.
    (d) Any manual on-off switches specifically associated with the 
battery charging process shall be switched on for the duration of the 
charge, maintenance, and no-battery mode tests, and switched off for the 
off mode test.

                3.2.5. Accessing the Battery for the Test

    (a) The technician may need to disassemble the end-use product or 
battery charger to gain access to the battery terminals for the Battery 
Discharge Energy Test in section 3.3.8 of this appendix. If the battery 
terminals are not clearly labeled, the technician shall use a voltmeter 
to identify the positive and negative terminals. These terminals will be 
the ones that give the largest voltage difference and are able to 
deliver significant current (0.2 C or 1/hr) into a load.
    (b) All conductors used for contacting the battery must be cleaned 
and burnished prior to connecting in order to decrease voltage drops and 
achieve consistent results.
    (c) Manufacturer's instructions for disassembly shall be followed, 
except those instructions that:
    (1) Lead to any permanent alteration of the battery charger 
circuitry or function;
    (2) Could alter the energy consumption of the battery charger 
compared to that experienced by a user during typical use, e.g., due to 
changes in the airflow through the enclosure of the UUT; or
    (3) Conflict requirements of this test procedure.
    (d) Care shall be taken by the technician during disassembly to 
follow appropriate safety precautions. If the functionality of the 
device or its safety features is compromised, the product shall be 
discarded after testing.
    (e) Some products may include protective circuitry between the 
battery cells and the remainder of the device. If the manufacturer 
provides a description for accessing the connections at the output of 
the protective circuitry, these connections shall be used to discharge 
the battery and measure the discharge energy. The energy consumed by the 
protective circuitry during discharge shall not be measured or credited 
as battery energy.
    (f) If the technician, despite diligent effort and use of the 
manufacturer's instructions, encounters any of the following conditions 
noted immediately below, the Battery Discharge Energy and the Charging 
and Maintenance Mode Energy shall be reported as ``Not Applicable'':
    (1) Inability to access the battery terminals;
    (2) Access to the battery terminals destroys charger functionality; 
or
    (3) Inability to draw current from the test battery.

     3.2.6. Determining Charge Capacity for Batteries With No Rating

    (a) If there is no rating for the battery charge capacity on the 
battery or in the instructions, then the technician shall determine a 
discharge current that meets the following requirements. The battery 
shall be fully charged and then discharged at this constant-current rate 
until it reaches the end-of-discharge voltage specified in Table

[[Page 719]]

3.3.2 of this appendix. The discharge time must be not less than 4.5 
hours nor more than 5 hours. In addition, the discharge test (section 
3.3.8 of this appendix) (which may not be starting with a fully-charged 
battery) shall reach the end-of-discharge voltage within 5 hours. The 
same discharge current shall be used for both the preparations step 
(section 3.3.4 of this appendix) and the discharge test (section 3.3.8 
of this appendix). The test report shall include the discharge current 
used and the resulting discharge times for both a fully-charged battery 
and for the discharge test.
    (b) For this section, the battery is considered as ``fully charged'' 
when either: it has been charged by the UUT until an indicator on the 
UUT shows that the charge is complete; or it has been charged by a 
battery analyzer at a current not greater than the discharge current 
until the battery analyzer indicates that the battery is fully charged.
    (c) When there is no capacity rating, a suitable discharge current 
must generally be determined by trial and error. Since the conditioning 
step does not require constant-current discharges, the trials themselves 
may also be counted as part of battery conditioning.

                          3.3. Test Measurement

    The test sequence to measure the battery charger energy consumption 
is summarized in Table 3.3.1 of this appendix, and explained in detail 
in this appendix. Measurements shall be made under test conditions and 
with the equipment specified in sections 3.1 and 3.2 of this appendix.

----------------------------------------------------------------------------------------------------------------

                3.3.1. Recording General Data on the UUT

    The technician shall record:
    (a) The manufacturer and model of the battery charger;
    (b) The presence and status of any additional functions unrelated to 
battery charging;
    (c) The manufacturer, model, and number of batteries in the test 
battery;
    (d) The nameplate battery voltage of the test battery;
    (e) The nameplate battery charge capacity of the test battery; and
    (f) The nameplate battery charge energy of the test battery.
    (g) The settings of the controls, if battery charger has user 
controls to select from two or more charge rates.

 3.3.2. Determining the Duration of the Charge and Maintenance Mode Test

    (a) The charging and maintenance mode test, described in detail in 
section 3.3.6 of this appendix, shall be 24 hours in length or longer, 
as determined by the items below. Proceed in order until a test duration 
is determined.
    (1) If the battery charger has an indicator to show that the battery 
is fully charged, that indicator shall be used as follows: If the 
indicator shows that the battery is charged after 19 hours of charging, 
the test shall be terminated at 24 hours. Conversely, if the full-charge 
indication is not yet present after 19 hours of charging, the test shall 
continue until 5 hours after the indication is present.

[[Page 720]]

    (2) If there is no indicator, but the manufacturer's instructions 
indicate that charging this battery or this capacity of battery should 
be complete within 19 hours, the test shall be for 24 hours. If the 
instructions indicate that charging may take longer than 19 hours, the 
test shall be run for the longest estimated charge time plus 5 hours.
    (3) If there is no indicator and no time estimate in the 
instructions, but the charging current is stated on the charger or in 
the instructions, calculate the test duration as the longer of 24 hours 
or:
[GRAPHIC] [TIFF OMITTED] TR12DE16.027

    (b) If none of the above applies, the duration of the test shall be 
24 hours.

                       3.3.3. Battery Conditioning

    (a) No conditioning is to be done on lithium-ion batteries. The test 
technician shall proceed directly to battery preparation, section 3.3.4 
of this appendix, when testing chargers for these batteries.
    (b) Products with integral batteries will have to be disassembled 
per the instructions in section 3.2.5 of this appendix, and the battery 
disconnected from the charger for discharging.
    (c) Batteries of other chemistries that have not been previously 
cycled are to be conditioned by performing two charges and two 
discharges, followed by a charge, as below. No data need be recorded 
during battery conditioning.
    (1) The test battery shall be fully charged for the duration 
specified in section 3.3.2 of this appendix or longer using the UUT.
    (2) The test battery shall then be fully discharged using either:
    (i) A battery analyzer at a rate not to exceed 1 C, until its 
average cell voltage under load reaches the end-of-discharge voltage 
specified in Table 3.3.2 of this appendix for the relevant battery 
chemistry; or
    (ii) The UUT, until the UUT ceases operation due to low battery 
voltage.
    (3) The test battery shall again be fully charged as in step (c)(1) 
of this section.
    (4) The test battery shall again be fully discharged as per step 
(c)(2) of this section.
    (5) The test battery shall be again fully charged as in step (c)(1) 
of this section.
    (d) Batteries of chemistries, other than lithium-ion, that are known 
to have been through at least two previous full charge/discharge cycles 
shall only be charged once per step (c)(5), of this section.

             3.3.4. Preparing the Battery for Charge Testing

    Following any conditioning prior to beginning the battery charge 
test (section 3.3.6 of this appendix), the test battery shall be fully 
discharged for the duration specified in section 3.3.2 of this appendix, 
or longer using a battery analyzer.

                       3.3.5. Resting the Battery

    The test battery shall be rested between preparation and the battery 
charge test. The rest period shall be at least one hour and not exceed 
24 hours. For batteries with flooded cells, the electrolyte temperature 
shall be less than 30 [deg]C before charging, even if the rest period 
must be extended longer than 24 hours.

         3.3.6. Testing Charge Mode and Battery Maintenance Mode

    (a) The Charge and Battery Maintenance Mode test measures the energy 
consumed during charge mode and some time spent in the maintenance mode 
of the UUT. Functions required for battery conditioning that happen only 
with some user-selected switch or other control shall not be included in 
this measurement. (The technician shall manually turn off any battery 
conditioning cycle or setting.) Regularly occurring battery conditioning 
or maintenance functions that are not controlled by the user will, by 
default, be incorporated into this measurement.
    (b) During the measurement period, input power values to the UUT 
shall be recorded at least once every minute.
    (1) If possible, the technician shall set the data logging system to 
record the average power during the sample interval. The total energy is 
computed as the sum of power samples (in watts) multiplied by the sample 
interval (in hours).
    (2) If this setting is not possible, then the power analyzer shall 
be set to integrate or accumulate the input power over the measurement 
period and this result shall be used as the total energy.
    (c) The technician shall follow these steps:
    (1) Ensure that the user-controllable device functionality not 
associated with battery charging and any battery conditioning cycle or 
setting are turned off, as instructed in section 3.2.4 of this appendix;
    (2) Ensure that the test battery used in this test has been 
conditioned, prepared, discharged, and rested as described in sections 
3.3.3 through 3.3.5 of this appendix;
    (3) Connect the data logging equipment to the battery charger;

[[Page 721]]

    (4) Record the start time of the measurement period, and begin 
logging the input power;
    (5) Connect the test battery to the battery charger within 3 minutes 
of beginning logging. For integral battery products, connect the product 
to a cradle or wall adapter within 3 minutes of beginning logging;
    (6) After the test battery is connected, record the initial time and 
power (W) of the input current to the UUT. These measurements shall be 
taken within the first 10 minutes of active charging;
    (7) Record the input power for the duration of the ``Charging and 
Maintenance Mode Test'' period, as determined by section 3.3.2 of this 
appendix. The actual time that power is connected to the UUT shall be 
within 5 minutes of the specified period; and
    (8) Disconnect power to the UUT, terminate data logging, and record 
the final time.

                       3.3.7. Resting the Battery

    The test battery shall be rested between charging and discharging. 
The rest period shall be at least 1 hour and not more than 4 hours, with 
an exception for flooded cells. For batteries with flooded cells, the 
electrolyte temperature shall be less than 30 [deg]C before charging, 
even if the rest period must be extended beyond 4 hours.

                  3.3.8. Battery Discharge Energy Test

    (a) If multiple batteries were charged simultaneously, the discharge 
energy is the sum of the discharge energies of all the batteries.
    (1) For a multi-port charger, batteries that were charged in 
separate ports shall be discharged independently.
    (2) For a batch charger, batteries that were charged as a group may 
be discharged individually, as a group, or in sub-groups connected in 
series and/or parallel. The position of each battery with respect to the 
other batteries need not be maintained.
    (b) During discharge, the battery voltage and discharge current 
shall be sampled and recorded at least once per minute. The values 
recorded may be average or instantaneous values.
    (c) For this test, the technician shall follow these steps:
    (1) Ensure that the test battery has been charged by the UUT and 
rested according to the procedures above.
    (2) Set the battery analyzer for a constant discharge rate and the 
end-of-discharge voltage in Table 3.3.2 of this appendix for the 
relevant battery chemistry.
    (3) Connect the test battery to the analyzer and begin recording the 
voltage, current, and wattage, if available from the battery analyzer. 
When the end-of-discharge voltage is reached or the UUT circuitry 
terminates the discharge, the test battery shall be returned to an open-
circuit condition. If current continues to be drawn from the test 
battery after the end-of-discharge condition is first reached, this 
additional energy is not to be counted in the battery discharge energy.
    (d) If not available from the battery analyzer, the battery 
discharge energy (in watt-hours) is calculated by multiplying the 
voltage (in volts), current (in amperes), and sample period (in hours) 
for each sample, and then summing over all sample periods until the end-
of-discharge voltage is reached.

              3.3.9. Determining the Maintenance Mode Power

    After the measurement period is complete, the technician shall 
determine the average maintenance mode power consumption by examining 
the power-versus-time data from the charge and maintenance test and:
    (a) If the maintenance mode power is cyclic or shows periodic 
pulses, compute the average power over a time period that spans a whole 
number of cycles and includes at least the last 4 hours.
    (b) Otherwise, calculate the average power value over the last 4 
hours.

           3.3.10. Determining the 24-Hour Energy Consumption

    The accumulated energy or the average input power, integrated over 
the test period from the charge and maintenance mode test, shall be used 
to calculate 24-hour energy consumption.

           3.3.11. Standby Mode Energy Consumption Measurement

    The standby mode measurement depends on the configuration of the 
battery charger, as follows.
    (a) Conduct a measurement of standby power consumption while the 
battery charger is connected to the power source. Disconnect the battery 
from the charger, allow the charger to operate for at least 30 minutes, 
and record the power (i.e., watts) consumed as the time series integral 
of the power consumed over a 10-minute test period, divided by the 
period of measurement. If the battery charger has manual on-off 
switches, all must be turned on for the duration of the standby mode 
test.
    (b) Standby mode may also apply to products with integral batteries. 
If the product uses a cradle and/or adapter for power conversion and 
charging, then ``disconnecting the battery from the charger'' will 
require disconnection of the end-use product, which contains the 
batteries. The other enclosures of the battery charging system will 
remain connected to the main electricity supply, and standby mode power 
consumption will equal that of the cradle and/or adapter alone.
    (c) If the product is powered through a detachable AC power cord and 
contains integrated power conversion and charging circuitry, then only 
the cord will remain connected to mains, and standby mode power 
consumption will equal that of the AC power cord (i.e., zero watts).
    (d) Finally, if the product contains integrated power conversion and 
charging circuitry but is powered through a non-detachable AC power cord 
or plug blades, then no part of the system will remain connected to 
mains, and standby mode measurement is not applicable.

             3.3.12. Off Mode Energy Consumption Measurement

    The off mode measurement depends on the configuration of the battery 
charger, as follows.
    (a) If the battery charger has manual on-off switches, record a 
measurement of off mode energy consumption while the battery charger is 
connected to the power source. Remove the battery from the charger, 
allow the charger to operate for at least 30 minutes, and record the 
power (i.e., watts) consumed as the time series integral of the power 
consumed over a 10-minute test period, divided by the period of 
measurement, with all manual on-off switches turned off. If the battery 
charger does not have manual on-off switches, record that the off mode 
measurement is not applicable to this product.
    (b) Off mode may also apply to products with integral batteries. If 
the product uses a cradle and/or adapter for power conversion and 
charging, then ``disconnecting the battery from the charger'' will 
require disconnection of the end-use product, which contains the 
batteries. The other enclosures of the battery charging system will 
remain connected to the main electricity supply, and off mode power 
consumption will equal that of the cradle and/or adapter alone.
    (c) If the product is powered through a detachable AC power cord and 
contains integrated power conversion and charging circuitry, then only 
the cord will remain connected to mains, and off mode power consumption 
will equal that of the AC power cord (i.e., zero watts).
    (d) Finally, if the product contains integrated power conversion and 
charging circuitry but is powered through a non-detachable AC power cord 
or plug blades, then no part of the system will remain connected to 
mains, and off mode measurement is not applicable.

               3.3.13. Unit Energy Consumption Calculation

    Unit energy consumption (UEC) shall be calculated for a battery 
charger using one of the two equations (equation (i) or equation (ii)) 
listed in this section. If a battery charger is tested and its charge 
duration as determined in section 3.3.2 of this appendix minus 5 hours 
is greater than the threshold charge time listed in table 3.3.3 of this 
appendix (i.e. (tcd - 5) * n  ta&m), 
equation (ii) shall be used to calculate UEC; otherwise a battery 
charger's UEC shall be calculated using equation (i).

       4. Testing Requirements for Uninterruptible Power Supplies

                      4.1. Standard Test Conditions

                       4.1.1. Measuring Equipment

    (a) The power or energy meter must provide true root mean square (r. 
m. s) measurements of the active input and output measurements, with an 
uncertainty at full rated load of less than or equal to 0.5% at the 95% 
confidence level notwithstanding that voltage and current waveforms can 
include harmonic components. The meter must measure input and output 
values simultaneously.
    (b) All measurement equipment used to conduct the tests must be 
calibrated within the measurement equipment manufacturer specified 
calibration period by a standard traceable to International System of 
Units such that measurements meet the uncertainty requirements specified 
in section 4.1.1(a) of this appendix.

                      4.1.2. Test Room Requirements

    All portions of the test must be carried out in a room with an air 
speed immediately surrounding the UUT of <=0.5 m/s in all directions. 
Maintain the ambient temperature in the range of 20.0 [deg]C to 30.0 
[deg]C, including all inaccuracies and uncertainties introduced by the 
temperature measurement equipment, throughout the test. No intentional 
cooling of the UUT, such as by use of separately powered fans, air 
conditioners, or heat sinks, is permitted. Test the UUT on a thermally 
non-conductive surface.

                4.1.3. Input Voltage and Input Frequency

    The AC input voltage and frequency to the UPS during testing must be 
within 3 percent

[[Page 724]]

of the highest rated voltage and within 1 percent of the highest rated 
frequency of the device.

                 4.2. Unit Under Test Setup Requirements

                          4.2.1. General Setup

    Configure the UPS according to Annex J.2 of IEC 62040-3 Ed. 2.0 
(incorporated by reference, see Sec. 430.3) with the following 
additional requirements:
    (a) UPS Operating Mode Conditions. If the UPS can operate in two or 
more distinct normal modes as more than one UPS architecture, conduct 
the test in its lowest input dependency as well as in its highest input 
dependency mode where VFD represents the lowest possible input 
dependency, followed by VI and then VFI.
    (b) Energy Storage System. The UPS must not be modified or adjusted 
to disable energy storage charging features. Minimize the transfer of 
energy to and from the energy storage system by ensuring the energy 
storage system is fully charged (at the start of testing) as follows:
    (1) If the UUT has a battery charge indicator, charge the battery 
for 5 hours after the UUT has indicated that it is fully charged.
    (2) If the UUT does not have a battery charge indicator but the user 
manual shipped with the UUT specifies a time to reach full charge, 
charge the battery for 5 hours longer than the time specified.
    (3) If the UUT does not have a battery charge indicator or user 
manual instructions, charge the battery for 24 hours.
    (c) DC output port(s). All DC output port(s) of the UUT must remain 
unloaded during testing.

                       4.2.2. Additional Features

    (a) Any feature unrelated to maintaining the energy storage system 
at full charge or delivery of load power (e.g., LCD display) shall be 
switched off. If it is not possible to switch such features off, they 
shall be set to their lowest power-consuming mode during the test.
    (b) If the UPS takes any physically separate connectors or cables 
not required for maintaining the energy storage system at full charge or 
delivery of load power but associated with other features (such as 
serial or USB connections, Ethernet, etc.), these connectors or cables 
shall be left disconnected during the test.
    (c) Any manual on-off switches specifically associated with 
maintaining the energy storage system at full charge or delivery of load 
power shall be switched on for the duration of the test.

                  4.3. Test Measurement and Calculation

    Efficiency can be calculated from either average power or 
accumulated energy.

                    4.3.1. Average Power Calculations

    If efficiency calculation are to be made using average power, 
calculate the average power consumption (Pavg) by sampling 
the power at a rate of at least 1 sample per second and computing the 
arithmetic mean of all samples over the time period specified for each 
test as follows:
[GRAPHIC] [TIFF OMITTED] TR12DE16.021

Where:

Pavg = average power
Pi = power measured during individual measurement (i)
n = total number of measurements

                           4.3.2. Steady State

    Operate the UUT and the load for a sufficient length of time to 
reach steady state conditions. To determine if steady state conditions 
have been attained, perform the following steady state check, in which 
the difference between the two efficiency calculations must be less than 
1 percent:
    (a)(1) Simultaneously measure the UUT's input and output power for 
at least 5 minutes, as specified in section 4.3.1 of this appendix, and 
record the average of each over the duration as Pavg\in and Pavg\out, 
respectively. Or,
    (2) Simultaneously measure the UUT's input and output energy for at 
least 5 minutes and record the accumulation of each over the duration as 
Ein and Eout, respectively.
    (b) Calculate the UUT's efficiency, Eff1, using one of the following 
two equations:

[[Page 725]]

[GRAPHIC] [TIFF OMITTED] TR12DE16.022

Where:

Eff is the UUT efficiency
Pavg\out is the average output power in watts
Pavg\in is the average input power in watts
[GRAPHIC] [TIFF OMITTED] TR12DE16.023

Where:

Eff is the UUT efficiency
Eout is the accumulated output energy in watt-hours
Ein in the accumulated input energy in watt-hours

    (c) Wait a minimum of 10 minutes.
    (d) Repeat the steps listed in paragraphs (a) and (b) of section 
4.3.2 of this appendix to calculate another efficiency value, Eff2.
    (e) Determine if the product is at steady state using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR12DE16.024

    If the percentage difference of Eff1 and Eff2 as described in the 
equation, is less than 1 percent, the product is at steady state.
    (f) If the percentage difference is greater than or equal to 1 
percent, the product is not at steady state. Repeat the steps listed in 
paragraphs (c) to (e) of section 4.3.2 of this appendix until the 
product is at steady state.

          4.3.3. Power Measurements and Efficiency Calculations

    Measure input and output power of the UUT according to Section J.3 
of Annex J of IEC 62040-3 Ed. 2.0 (incorporated by reference, see Sec. 
430.3), or measure the input and output energy of the UUT for efficiency 
calculations with the following exceptions:
    (a) Test the UUT at the following reference test load conditions, in 
the following order: 100 percent, 75 percent, 50 percent, and 25 percent 
of the rated output power.
    (b) Perform the test at each of the reference test loads by 
simultaneously measuring the UUT's input and output power in Watts (W), 
or input and output energy in Watt-Hours (Wh) over a 15 minute test 
period at a rate of at least 1 Hz. Calculate the efficiency for that 
reference load using one of the following two equations:
[GRAPHIC] [TIFF OMITTED] TR12DE16.025


[[Page 726]]


Where:

Effn = the efficiency at reference test load n%
Pavg\out n = the average output power at reference load n%
Pavg\in n = the average input power at reference load n%
[GRAPHIC] [TIFF OMITTED] TR12DE16.026

Where:

Effn = the efficiency at reference test load n%
Eout n = the accumulated output energy at reference load n%
Ein n = the accumulated input energy at reference load n%

                        4.3.4. UUT Classification

    Optional Test for determination of UPS architecture. Determine the 
UPS architecture by performing the tests specified in the definitions of 
VI, VFD, and VFI (sections 2.28.1 through 2.28.3 of this appendix).

                  4.3.5. Output Efficiency Calculation

    (a) Use the load weightings from Table 4.3.1 to determine the 
average load adjusted efficiency as follows:
[GRAPHIC] [TIFF OMITTED] TR12DE16.029

Where:

Effavg = the average load adjusted efficiency
tn = the portion of time spent at reference test load n% as 
          specified in Table 4.3.1
Eff[bond]n = the measured efficiency at reference test load n%

   Sec. Appendix Z to Subpart B of Part 430--Uniform Test Method for 
       Measuring the Energy Consumption of External Power Supplies

    Starting on February 21, 2016, any representations made with respect 
to the energy

[[Page 727]]

use or efficiency of external power supplies must be made in accordance 
with the results of testing pursuant to this appendix. Prior to February

this appendix or Appendix Z as it appeared at 10 CFR part 430, subpart 
B, Appendix Z as contained in the 10 CFR parts 200 to 499 edition 
revised as of January 1, 2015. Because representations must be made in 
accordance with tests conducted pursuant to this appendix as of February 
21, 2016, manufacturers may wish to begin using this test procedure as 
soon as possible.

                                1. Scope.

supply).
    b. Active mode efficiency is the ratio, expressed as a percentage, 
of the total real output power produced by a power supply to the real 
input power required to produce it. (Reference for guidance only, see 
IEEE Standard 1515-2000, 4.3.1.1, Sec. 430.4.)
    c. Active power (P) (also real power) means the average power

optical, or electronic switches that automatically disconnect mains 
power from the device when a load is disconnected from the device, or 
that control power to the load itself.
    j. Minimum output current means the minimum current that must be 
drawn from an output bus for an external power supply to operate within 
its specifications.
    k. Multiple-voltage external power supply means an external power 
supply that is designed to convert line voltage AC input into more than 
one simultaneous lower-voltage output.

power supply as specified on the manufacturer's label on the power 
supply housing.
    m. Nameplate input voltage means the AC input voltage of the power 
supply as specified on the manufacturer's label on the power supply 
housing.
    n. Nameplate output current means the current output of the power

``all outputs are'' for a multiple-voltage external power supply) not 
connected to a load (or ``loads'' for a multiple-voltage external power 
supply).
    r. Off mode is the condition, applicable only to units with manual 
on-off switches, in which the external power supply is (1) connected to 
the main electricity supply; (2) the output is not connected to any 
load; and (3) all manual on-off switches are turned off.
    s. Output bus means any of the outputs of the power supply to which 
loads can be connected and from which power can be drawn, as opposed to 
signal connections used for communication.

[[Page 728]]

    t. Single-voltage external AC-AC power supply means an external 
power supply that is designed to convert line voltage AC input into 
lower voltage AC output and is able to convert to only one AC output 
voltage at a time.
    u. Single-voltage external AC-DC power supply means an external

single-voltage AC-AC or AC-DC power supply that allows users to choose 
from more than one output voltage.
    x. Total harmonic distortion, expressed as a percentage, is the RMS 
value of an AC signal after the fundamental component is removed and 
interharmonic components are ignored, divided by the RMS value of the 
fundamental component. THD of current is defined as:
[GRAPHIC] [TIFF OMITTED] TR27MR09.409

where In is the RMS value of the nth harmonic of the current signal.

    y. True power factor (PF) is the ratio of the active power (P) 
consumed in watts to the apparent power (S), drawn in volt-amperes.
[GRAPHIC] [TIFF OMITTED] TR27MR09.410

This definition of power factor includes the effect of both distortion 
and displacement.

    z. Unit under test is the external power supply being tested.
    3. Test Apparatus and General Instructions:
    (a) Single-Voltage External Power Supply.
    (i) Any power measurements recorded, as well as any power 
measurement equipment utilized for testing, shall conform to the 
uncertainty and resolution requirements outlined in Section 4, ``General 
conditions for measurements,'' as well as Annexes B, ``Notes on the 
measurement of low power modes,'' and D, ``Determination of uncertainty 
of measurement,'' of IEC 62301 (incorporated by reference; see Sec. 
430.3).
    (ii) As is specified in IEC 62301 (incorporated by reference; see 
Sec. 430.3), the tests shall be carried out in a room that has an air 
speed close to the unit under test (UUT) of <=0.5 m/s. The ambient 
temperature shall be maintained at 20  5 [deg]C 
throughout the test. There shall be no intentional cooling of the UUT by 
use of separately powered fans, air conditioners, or heat sinks. The UUT 
shall be tested on a thermally non-conductive surface. Products intended 
for outdoor use may be tested at additional temperatures, provided those 
are in addition to the conditions specified above and are noted in a 
separate section on the test report.
    (iii) If the UUT is intended for operation on AC line-voltage input 
in the United States, it shall be tested at 115 V at 60 Hz. If the UUT 
is intended for operation on AC line-voltage input but cannot be 
operated at 115 V at 60 Hz, it shall not be tested. The input voltage 
shall be within 1 percent of the above specified 
voltage.
    (iv) The input voltage source must be capable of delivering at least 
10 times the nameplate input power of the UUT as is specified in IEEE 
1515-2000 (Referenced for guidance only, see Sec. 430.4). Regardless of 
the AC source type, the THD of the supply voltage when supplying the UUT 
in the specified mode must not exceed 2%, up to and including the 13th 
harmonic (as specified in IEC 62301). The peak value of the test voltage 
must be within 1.34 and 1.49 times its RMS value (as specified in IEC 
62301 (incorporated by reference; see Sec. 430.3)).
    (v) Select all leads used in the test set-up as specified in Table 
B.2-- ``Commonly used values for wire gages and related voltage drops'' 
in IEEE 15152000.
    (b) Multiple-Voltage External Power Supply. Unless otherwise 
specified, measurements shall be made under test conditions and with 
equipment specified below.
    (i) Verifying Accuracy and Precision of Measuring Equipment
    (A) Any power measurements recorded, as well as any power 
measurement equipment utilized for testing, must conform to the 
uncertainty and resolution requirements outlined in Section 4, ``General 
conditions for measurements'', as well as Annexes B, ``Notes on the 
measurement of low power modes'', and D, ``Determination of uncertainty 
of measurement'', of IEC 62301 (incorporated by reference; see Sec. 
430.3).
    (B) [Reserved]

                      (ii) Setting Up the Test Room

    All tests shall be carried out in a room with an air speed 
immediately surrounding the UUT of <=0.5 m/s. The ambient temperature 
shall be maintained at 20 [deg]C 5 [deg]C 
throughout the test. There shall be no intentional cooling of the UUT 
such as by use of separately powered fans, air conditioners, or heat 
sinks. The UUT shall be conditioned, rested, and tested on a thermally 
non-conductive surface. A readily available material such as Styrofoam 
will be sufficient.

[[Page 729]]

       (iii) Verifying the UUT's Input Voltage and Input Frequency

    (A) If the UUT is intended for operation on AC line-voltage input in 
the United States, it shall be tested at 115 V at 60 Hz. If the UUT is 
intended for operation on AC line-voltage input but cannot be operated 
at 115 V at 60 Hz, it shall not be tested. The input voltage shall be 
within 1 percent of the above specified voltage.
    (B) If the input voltage is AC, the input frequency shall be within 
1 percent of the specified frequency. The THD of 
the input voltage shall be <=2 percent, up to and including the 13th 
harmonic. The crest factor of the input voltage shall be between 1.34 
and 1.49.
    4. Test Measurement:
    (a) Single-Voltage External Power Supply

              (i) Standby Mode and Active-Mode Measurement.

    (A) Any built-in switch in the UUT controlling power flow to the AC 
input must be in the ``on'' position for this measurement, and note the 
existence of such a switch in the final test report. Test power supplies 
packaged for consumer use to power a product with the DC output cord 
supplied by the manufacturer. There are two options for connecting 
metering equipment to the output of this type of power supply: Cut the 
cord immediately adjacent to the DC output connector, or attach leads 
and measure the efficiency from the output connector itself. If the 
power supply is attached directly to the product that it is powering, 
cut the cord immediately adjacent to the powered product and connect DC 
measurement probes at that point. Any additional metering equipment such 
as voltmeters and/or ammeters used in conjunction with resistive or 
electronic loads must be connected directly to the end of the output 
cable of the UUT. If the product has more than two output wires, 
including those that are necessary for controlling the product, the 
manufacturer must supply a connection diagram or test fixture that will 
allow the testing laboratory to put the unit under test into active-
mode. Figure 1 provides one illustration of how to set up an EPS for 
test; however, the actual test setup may vary pursuant to the 
requirements of this paragraph.
[GRAPHIC] [TIFF OMITTED] TR25AU15.001

    (B) External power supplies must be tested in their final, completed 
configuration in order to represent their measured efficiency

[[Page 730]]

on product labels or specification sheets. Although the same procedure 
may be used to test the efficiency of a bare circuit board power supply 
prior to its incorporation into a finished housing and the attachment of 
its DC output cord, the efficiency of the bare circuit board power 
supply may not be used to characterize the efficiency of the final 
product (once enclosed in a case and fitted with a DC output cord). For 
example, a power supply manufacturer or component manufacturer may wish 
to assess the efficiency of a design that it intends to provide to an 
OEM for incorporation into a finished external power supply, but these 
results may not be used to represent the efficiency of the finished 
external power supply.
    (C) All single voltage external AC-DC power supplies have a 
nameplate output current. This is the value used to determine the four 
active-mode load conditions and the no load condition required by this 
test procedure. The UUT shall be tested at the following load 
conditions:

    Table 1--Loading Conditions for a Single-Voltage Unit Under Test
------------------------------------------------------------------------
 
------------------------------------------------------------------------
                 Percentage of Nameplate Output Current
------------------------------------------------------------------------
Load Condition 1..........................  100% of Nameplate Output
                                             Current 2%.
Load Condition 2..........................  75% of Nameplate Output
                                             Current 2%.
Load Condition 3..........................  50% of Nameplate Output
                                             Current 2%.
Load Condition 4..........................  25% of Nameplate Output
                                             Current 2%.
Load Condition 5..........................  0%.
------------------------------------------------------------------------

    The 2% allowance is of nameplate output current, not of the 
calculated current value. For example, a UUT at Load Condition 3 may be 
tested in a range from 48% to 52% of rated output current. Additional 
load conditions may be selected at the technician's discretion, as 
described in IEEE 1515-2000 (Referenced for guidance only, see Sec. 
430.4), but are not required by this test procedure. For Loading 
Condition 5, place the UUT in no-load mode, disconnect any additional 
signal connections to the UUT, and measure input power.
    1. Where the external power supply lists both an instantaneous and 
continuous output current, test the external power supply at the 
continuous condition only.
    2. If an external power supply cannot sustain output at one or more 
of loading conditions 1-4 as specified in Table 1, test the external 
power supply only at the loading conditions for which it can sustain 
output. In these cases, the average active mode efficiency is the 
average of the loading conditions for which it can sustain the output.
    (D) Test switch-selectable single-voltage external power supplies 
twice--once at the highest nameplate output voltage and once at the 
lowest.
    (E) Test adaptive external power supplies twice--once at the highest 
achievable output voltage and once at the lowest.
    (F) In order to load the power supply to produce all four active-
mode load conditions, use a set of variable resistive or electronic 
loads. Although these loads may have different characteristics than the 
electronic loads power supplies are intended to power, they provide 
standardized and readily repeatable references for testing and product 
comparison. Note that resistive loads need not be measured precisely 
with an ohmmeter; simply adjust a variable resistor to the point where 
the ammeter confirms that the desired percentage of nameplate output 
current is flowing. For electronic loads, adjust the desired output 
current in constant current (CC) mode rather than adjusting the required 
output power in constant power (CP) mode.
    (G) As noted in IEC 62301 (incorporated by reference; see Sec. 
430.3), instantaneous measurements are appropriate when power readings 
are stable in a particular load condition. Operate the UUT at 100% of 
nameplate current output for at least 30 minutes immediately prior to 
conducting efficiency measurements. After this warm-up period, monitor 
AC input power for a period of 5 minutes to assess the stability of the 
UUT. If the power level does not drift by more than 5% from the maximum 
value observed, the UUT is considered stable and the measurements should 
be recorded at the end of the 5-minute period. Measure subsequent load 
conditions under the same 5-minute stability parameters. Note that only 
one warm-up period of 30 minutes is required for each UUT at the 
beginning of the test procedure. If the AC input power is not stable 
over a 5-minute period, follow the guidelines established by IEC 62301 
for measuring average power or accumulated energy over time for both AC 
input and DC output. Conduct efficiency measurements in sequence from 
Load Condition 1 to Load Condition 5 as indicated in Table 1. If testing 
of additional, optional load conditions is desired, that testing should 
be conducted in accordance with this test procedure and subsequent to 
completing the sequence described above.
    (H) Calculate efficiency by dividing the UUT's measured DC output 
power at a given load condition by the true AC input power measured at 
that load condition. Calculate average efficiency as the arithmetic mean 
of the efficiency values calculated at Test Conditions 1, 2, 3, and 4 in 
Table 1, and record this value. Average efficiency for the UUT is a 
simple arithmetic average of active-mode efficiency values, and is not 
intended to represent weighted average efficiency, which would vary 
according to the duty cycle of the product powered by the UUT.
    (I) Power consumption of the UUT at each Load Condition 1-4 is the 
difference between

[[Page 731]]

the DC output power (W) at that Load Condition and the AC input power 
(W) at that Load Condition. The power consumption of Load Condition 5 
(no load) is equal to the AC input power (W) at that Load Condition.
    (ii) Off-Mode Measurement--If the external power supply UUT 
incorporates manual on-off switches, place the UUT in off-mode, and 
measure and record its power consumption at ``Load Condition 5'' in 
Table 1. The measurement of the off-mode energy consumption must conform 
to the requirements specified in paragraph 4(a)(i) of this appendix, 
except that all manual on-off switches must be placed in the ``off'' 
position for the off-mode measurement. The UUT is considered stable if, 
over 5 minutes with samples taken at least once every second, the AC 
input power does not drift from the maximum value observed by more than 
1 percent or 50 milliwatts, whichever is greater. Measure the off-mode 
power consumption of a switch-selectable single-voltage external power 
supply twice--once at the highest nameplate output voltage and once at 
the lowest.
    (b) Multiple-Voltage External Power Supply--Power supplies must be 
tested with the output cord packaged with the unit for sale to the 
consumer, as it is considered part of the unit under test. There are two 
options for connecting metering equipment to the output of this type of 
power supply: cut the cord immediately adjacent to the output connector 
or attach leads and measure the efficiency from the output connector 
itself. If the power supply is attached directly to the product that it 
is powering, cut the cord immediately adjacent to the powered product 
and connect output measurement probes at that point. The tests should be 
conducted on the sets of output wires that constitute the output busses. 
If the product has additional wires, these should be left electrically 
disconnected unless they are necessary for controlling the product. In 
this case, the manufacturer shall supply a connection diagram or test 
fixture that will allow the testing laboratory to put the unit under 
test into active mode.
    (i) Standby-Mode and Active-Mode Measurement--The measurement of the 
multiple-voltage external power supply standby mode (also no-load-mode) 
energy consumption and active-mode efficiency shall be as follows:
    (A) Loading conditions and testing sequence. (1) If the unit under 
test has on-off switches, all switches shall be placed in the ``on'' 
position. Loading criteria for multiple-voltage external power supplies 
shall be based on nameplate output current and not on nameplate output 
power because output voltage might not remain constant.
    (2) The unit under test shall operate at 100 percent of nameplate 
current output for at least 30 minutes immediately before conducting 
efficiency measurements.
    (3) After this warm-up period, the technician shall monitor AC input 
power for a period of 5 minutes to assess the stability of the unit 
under test. If the power level does not drift by more than 1 percent 
from the maximum value observed, the unit under test can be considered 
stable and measurements can be recorded at the end of the 5-minute 
period. Measurements at subsequent loading conditions, listed in Table 
1, can then be conducted under the same 5-minute stability guidelines. 
Only one warm-up period of 30 minutes is required for each unit under 
test at the beginning of the test procedure.
    (4) If AC input power is not stable over a 5-minute period, the 
technician shall follow the guidelines established by IEC Standard 62301 
for measuring average power or accumulated energy over time for both 
input and output. (Reference for guidance only, see Sec. 430.4).
    (5) The unit under test shall be tested at the loading conditions 
listed in Table 1, derated per the proportional allocation method 
presented in the following section.

             Table 1--Loading Conditions for Unit Under Test
------------------------------------------------------------------------
 
------------------------------------------------------------------------
Loading Condition 1.......................  100% of Derated Nameplate
                                             Output Current 2%.
Loading Condition 2.......................  75% of Derated Nameplate
                                             Output Current 2%.
Loading Condition 3.......................  50% of Derated Nameplate
                                             Output Current 2%.
Loading Condition 4.......................  25% of Derated Nameplate
                                             Output Current 2%.
Loading Condition 5.......................  0%.
------------------------------------------------------------------------

    (6) Input and output power measurements shall be conducted in 
sequence from Loading Condition 1 to Loading Condition 4, as indicated 
in Table 1. For Loading Condition 5, the unit under test shall be placed 
in no-load mode, any additional signal connections to the unit under 
test shall be disconnected, and input power shall be measured.
    (B) Proportional allocation method for loading multiple-voltage 
external power supplies. For power supplies with multiple voltage 
busses, defining consistent loading criteria is difficult because each 
bus has its own nameplate output current. The sum of the power 
dissipated by each bus loaded to its nameplate output current may exceed 
the overall nameplate output power of the power supply. The following 
proportional allocation method must be used to provide consistent 
loading conditions for multiple-voltage external power supplies. For 
additional explanation, please refer to section 6.1.1 of the California 
Energy Commission's ``Proposed Test Protocol for Calculating the Energy 
Efficiency of Internal Ac-Dc Power Supplies Revision 6.2,'' November 
2007.
    (1) Consider a multiple-voltage power supply with N output busses, 
and nameplate

[[Page 732]]

output voltages V1, * * *, VN, corresponding output current ratings I1, 
* * *, IN, and a nameplate output power P. Calculate the derating factor 
D by dividing the power supply nameplate output power P by the sum of 
the nameplate output powers of the individual output busses, equal to 
the product of bus nameplate output voltage and current IiVi, as 
follows:
[GRAPHIC] [TIFF OMITTED] TR01JN11.023

    (2) If D =1, then loading every bus to its nameplate 
output current does not exceed the overall nameplate output power for 
the power supply. In this case, each output bus will simply be loaded to 
the percentages of its nameplate output current listed in Table 1. 
However, if D <1, it is an indication that loading each bus to its 
nameplate output current will exceed the overall nameplate output power 
for the power supply. In this case, and at each loading condition, each 
output bus will be loaded to the appropriate percentage of its nameplate 
output current listed in Table 1, multiplied by the derating factor D.
    (C) Minimum output current requirements. Depending on their 
application, some multiple-voltage power supplies may require a minimum 
output current for each output bus of the power supply for correct 
operation. In these cases, ensure that the load current for each output 
at Loading Condition 4 in Table 1 is greater than the minimum output 
current requirement. Thus, if the test method's calculated load current 
for a given voltage bus is smaller than the minimum output current 
requirement, the minimum output current must be used to load the bus. 
This load current shall be properly recorded in any test report.
    (D) Test loads. Active loads such as electronic loads or passive 
loads such as rheostats used for efficiency testing of the unit under 
test shall be able to maintain the required current loading set point 
for each output voltage within an accuracy of 0.5 
percent. If electronic load banks are used, their settings should be 
adjusted such that they provide a constant current load to the unit 
under test.
    (E) Efficiency calculation. Efficiency shall be calculated by 
dividing the measured active output power of the unit under test at a 
given loading condition by the active AC input power measured at that 
loading condition. Efficiency shall be calculated at each Loading 
Condition (1, 2, 3, and 4, in Table 1) and be recorded separately.
    (F) Power consumption calculation. Power consumption of the unit 
under test at Loading Conditions 1, 2, 3, and 4 is the difference 
between the active output power at that Loading Condition and the active 
AC input power at that Loading Condition. The power consumption of 
Loading Condition 5 (no-load) is equal to the AC active input power at 
that Loading Condition.
    (ii) Off Mode Measurement--If the multiple-voltage external power 
supply unit under test incorporates any on-off switches, the unit under 
test shall be placed in off mode and its power consumption in off mode 
measured and recorded. The measurement of the off mode energy 
consumption shall conform to the requirements specified in paragraph 
(4)(b)(i) of this appendix. Note that the only loading condition that 
will be measured for off mode is ``Loading Condition 5'' in paragraph 
(A), ``Loading conditions and testing sequence'', except that all manual 
on-off switches shall be placed in the off position for the measurement.

   Sec. Appendix AA to Subpart B of Part 430--Uniform Test Method for 
            Measuring the Energy Consumption of Furnace Fans

    Note: Any representation made after July 2, 2014 for energy 
consumption of furnace fans must be based upon results generated under 
this test procedure. Upon the compliance date(s) of any energy 
conservation standard(s) for furnace fans, use of the applicable 
provisions of this test procedure to demonstrate compliance with the 
energy conservation standard will also be required.
    1. Scope. This appendix covers the test requirements used to measure 
the energy consumption of fans used in weatherized and non-weatherized 
gas furnaces, oil furnaces, electric furnaces, and modular blowers.
    2. Definitions. Definitions include the definitions as specified in 
section 3 of ASHRAE 103-2007 (incorporated by reference, see Sec.

Fuel Utilization Efficiency of Residential Central Furnaces and 
Boilers''. Only those sections of ASHRAE 103-2007 (incorporated by 
reference; see Sec. 430.3) specifically referenced in this test 
procedure are part of this test procedure. In cases where there is a 
conflict, the language of the test procedure in this appendix takes 
precedence over ASHRAE 103-2007.
    2.4. ANSI/ASHRAE Standard 41.1-1986 (RA 2006) means the test 
standard published in 1986, approved by ANSI on February 18, 1987, 
reaffirmed in 2006, and entitled ``Standard Method for Temperature 
Measurement'' (incorporated by reference; see Sec. 430.3).
    2.5. ASHRAE Standard 37-2009 means the test standard published in 
2009 by ASHRAE entitled ``Methods of Testing for Rating Unitary Air-
Conditioning and Heat Pump Equipment'' (incorporated by reference; see 
Sec. 430.3).
    2.6. Default airflow-control settings are the airflow-control 
settings specified for installed-use by the manufacturer. For the 
purposes of this appendix, manufacturer specifications for installed-use 
are those specifications provided for typical consumer installations in 
the product literature shipped with the product in which the furnace fan 
is installed. In instances where a manufacturer specifies multiple 
airflow-control settings for a given function to account for varying 
installation scenarios, the highest airflow-control setting specified 
for the given function shall be used for the procedures specified in 
this appendix.
    2.7. External static pressure (ESP) means the difference between 
static pressures measured in the outlet duct and return air opening (or 
return air duct when used for testing) of the product in which the 
furnace fan is integrated.
    2.8. Furnace fan means an electrically-powered device used in a 
consumer product for the purpose of circulating air through ductwork.

furnace fan is integrated either is not connected to the power source or 
is connected to the power source but not energized.
    2.11. Seasonal off switch means a switch on the product in which the 
furnace fan is integrated that, when activated, results in a measurable 
change in energy consumption between the standby and off modes.
    2.12. Standby mode means the condition in which the product in which 
the furnace fan is integrated is connected to the power source, 
energized, but the furnace fan is not circulating air.
    2.13. Thermal stack damper means a type of stack damper that opens 
only during the direct conversion of thermal energy of the stack gases.
    3. Classifications. Classifications are as specified in section 4 of 
ASHRAE 103-2007 (incorporated by reference, see Sec. 430.3).
    4. Requirements. Requirements are as specified in section 5 of 
ASHRAE 103-2007 (incorporated by reference, see Sec. 430.3). In 
addition, Fan Energy Rating (FER) of furnace fans shall be determined 
using test data and estimated national average operating hours pursuant 
to section 10.10 of this appendix.

appendix.
    5.1. Temperature. Temperature measuring instruments shall meet the 
provisions specified in section 5.1 of ASHRAE 37-2009 (incorporated by 
reference, see Sec. 430.3) and shall be accurate to within 0.75 degree 
Fahrenheit (within 0.4 degrees Celsius).
    5.1.1. Outlet Air Temperature Thermocouple Grid. Outlet air 
temperature shall be measured as described in section 8.2.1.5.5 of 
ASHRAE 103-2007 (incorporated by reference, see Sec. 430.3) and 
illustrated in Figure 2 of ASHRAE 103-2007. Thermocouples shall be 
placed downstream of pressure taps used for external static pressure 
measurement.
    5.2. Humidity. Air humidity shall be measured with a relative 
humidity sensor that is accurate to within 5% relative humidity. Air 
humidity shall be measured as close as possible to the inlet of the 
product in which the furnace fan is installed.
    6. Apparatus. The apparatus used in conjunction with the furnace 
during the testing shall be as specified in section 7 of ASHRAE 103-2007 
(incorporated by reference, see Sec. 430.3) except for section 7.1, the 
second paragraph of section 7.2.2.2, section 7.2.2.5, and section 7.7, 
and as specified in sections 6.1, 6.2, 6.3,6.4, 6.5 and 6.6 of this 
appendix.
    6.1. General. The product in which the furnace fan is integrated

which the furnace fan is integrated. Each piece of the apparatus shall 
conform to material and construction specifications and the reference 
standard cited. Test rooms containing equipment shall have suitable 
facilities for providing the utilities necessary for performance of the 
test and be able to maintain conditions within the limits specified.
    6.2. Downflow furnaces. Install the internal section of vent pipe 
the same size as the flue collar for connecting the flue collar to the 
top of the unit, if not supplied by the manufacturer. Do not insulate 
the internal vent pipe during the jacket loss test (if conducted) 
described in section 8.6 of ASHRAE 103-2007 (incorporated by reference, 
see Sec. 430.3) or the steady-state test described in section 9.1 of 
ASHRAE 103-2007. Do not insulate the internal vent pipe before the cool-
down and heat-up tests described in sections 9.5 and 9.6, respectively, 
of ASHRAE 103-2007. If the vent pipe is surrounded by a metal jacket, do 
not insulate the metal jacket. Install a 5-ft test stack of the same 
cross sectional area or perimeter as the vent pipe above the top of the 
furnace. Tape or seal around the junction connecting the vent pipe and 
the 5-ft test stack. Insulate the 5-ft test stack with insulation having 
a minimum R-value of 7 and an outer layer of aluminum foil. (See Figure 
3-E of ASHRAE 103-2007.)
    6.3. Modular Blowers. A modular blower shall be equipped with the 
electric heat resistance kit that is likely to have the largest volume 
of retail sales with that particular basic model of modular blower.
    6.4. Ducts and Plenums. Ducts and plenums shall be built to the 
geometrical specifications in section 7 of ASHRAE 103-2007. An apparatus 
for measuring external static pressure shall be integrated in the plenum 
and test duct as specified in sections 6.4, excluding specifications 
regarding the minimum length of the ducting and minimum distance between 
the external static pressure taps and product inlet and outlet, and 6.5 
of ASHRAE 37-2009 (incorporated by reference, see Sec. 430.3). External 
static pressure measuring instruments shall be placed between the 
furnace openings and any restrictions or elbows in the test plenums or 
ducts. For all test configurations, external static pressure taps shall 
be placed 18 inches from the outlet.
    6.4.1. For tests conducted using a return air duct. Additional 
external static pressure taps shall be placed 12 inches from the product 
inlet. Pressure shall be directly measured as a differential pressure as 
depicted in Figure 8 of ASHRAE 37-2009 rather than determined by 
separately measuring inlet and outlet static pressure and subtracting 
the results.
    6.4.2. For tests conducted without a return air duct. External 
static pressure shall be directly measured as the differential pressure 
between the outlet duct static pressure and the ambient static pressure 
as depicted in Figure 7a of ASHRAE 37-2009.
    6.5. Air Filters. Air filters shall be removed.
    6.6. Electrical Measurement. Only electrical input power to the 
furnace fan (and electric resistance heat kit for electric furnaces and 
modular blowers) shall be measured for the purposes of this appendix. 
Electrical input power to the furnace fan and electric resistance hate 
kit shall be sub-metered separately. Electrical input power to all other 
electricity-consuming components of the product in which the furnace fan 
is integrated shall not be included in the electrical input power 
measurements used in the FER calculation. If the procedures of this 
appendix are being conducted at the same time as another test that 
requires metering of components other than the furnace fan and electric 
resistance heat kit, the electrical input power to the furnace fan and 
electric resistance heat kit shall be sub-metered separately from one 
another and separately from other electrical input power measurements.
    7. Test Conditions. The testing conditions shall be as specified in 
section 8, not including section 8.6.1.1, of ASHRAE 103-2007 
(incorporated by reference, see Sec. 430.3); and as specified in 
section 7.1 of this appendix.
    7.1. Measurement of Jacket Surface Temperature (optional). The 
jacket of the furnace or boiler shall be subdivided into 6-inch squares 
when practical, and otherwise into 36-square-inch regions comprising 4 
in. x 9 in. or 3 in. x 12 in. sections, and the surface temperature at 
the center of each square or section shall be determined with a surface 
thermocouple. The 36-square-inch areas shall be recorded in groups where 
the temperature differential of the 36-square-inch area is less than 10 
[deg]F for temperature up to 100 [deg]F above room temperature and less 
than 20 [deg]F for temperature more than 100 [deg]F above room 
temperature. For forced air central furnaces, the circulating air blower 
compartment is considered as part of the duct system and no surface 
temperature measurement of the blower compartment needs to be recorded 
for the purpose of this test. For downflow furnaces, measure all cabinet 
surface temperatures of the heat exchanger and combustion section, 
including the bottom around the outlet duct, and the burner door, using 
the 36 square-inch thermocouple grid. The cabinet surface temperatures 
around the blower section do not need to be measured (see figure 3-E of 
ASHRAE 103-2007.)
    8. Test Procedure. Testing and measurements shall be as specified in 
section 9 of ASHRAE 103-2007 (incorporated by reference, see Sec. 
430.3) except for sections 9.1.2.1, 9.3, 9.5.1.1, 9.5.1.2.1, 9.5.1.2.2, 
9.5.2.1, and section 9.7.1; and as specified in sections 8.1 through 8.6 
of this appendix.

steady-state conditions are attained as specified in section 8.3, 8.4, 
and 8.5 of this appendix. Measure furnace fan electrical input power 
(ECirc) and external static pressure (ESPCirc).
    8.6.3. Heating airflow-control setting measurements. For single-
stage gas and oil furnaces, the burner shall be fired at the maximum 
heat input rate. For single-stage electric furnaces, the electric 
heating elements shall be energized at the maximum heat input rate. For 
multi-stage and modulating furnaces the reduced heat input rate settings 
shall be used. Burner adjustments shall be made as specified by section 
8.4.1 of ASHRAE 103-2007 (incorporated by reference, see Sec. 430.3). 
After the burner is activated and adjusted or the electric heating 
elements are energized, the furnace fan controls shall be adjusted to 
operate the fan in the default heat airflow-control setting. In 
instances where a manufacturer specifies multiple airflow-control 
settings for a given function to account for varying installation 
scenarios, the highest airflow-control setting specified for the given

   Sec. Appendix BB to Subpart B of Part 430--Uniform Test Method for 
Measuring the Input Power, Lumen Output, Lamp Efficacy, Correlated Color 
 Temperature (CCT), Color Rendering Index (CRI), Power Factor, Time to 
Failure, and Standby Mode Power of Integrated Light-Emitting Diode (LED) 
                                  Lamps

    Note: On or after December 28, 2016, any representations made with 
respect to the energy use or efficiency of integrated light-emitting 
diode lamps must be made in accordance with the results of testing 
pursuant to this appendix.
    1. Scope: This appendix specifies the test methods required to 
measure input power, lumen output, lamp efficacy, CCT, CRI, power 
factor, time to failure, and standby mode power for integrated LED 
lamps.

                             2. Definitions

    2.1. The definitions specified in section 1.3 of IES LM-79-08 except 
section 1.3(f) (incorporated by reference; see Sec. 430.3) apply.
    2.2. Initial lumen output means the measured lumen output after the 
lamp is initially energized and stabilized using the stabilization 
procedures in section 3 of this appendix.
    2.3. Interval lumen output means the measured lumen output at 
constant intervals after the initial lumen output measurement in 
accordance with section 4 of this appendix.
    2.4. Rated input voltage means the voltage(s) marked on the lamp as 
the intended operating voltage. If not marked on the lamp, assume 120 V.
    2.5. Test duration means the operating time of the LED lamp after 
the initial lumen output measurement and before, during, and including 
the final lumen output measurement, in units of hours.
    2.6. Time to failure means the time elapsed between the initial 
lumen output measurement and the point at which the lamp reaches 70 
percent lumen maintenance as measured in section 4 of this appendix.

 3. Active Mode Test Method for Determining Lumen Output, Input Power, 
                CCT, CRI, Power Factor, and Lamp Efficacy

    In cases where there is a conflict, the language of the test 
procedure in this appendix takes precedence over IES LM-79-08 
(incorporated by reference; see Sec. 430.3).

LM-79-08 (incorporated by reference; see Sec. 430.3), respectively.
    3.1.2. Position an equal number of integrated LED lamps in the base-
up and base-down orientations throughout testing; if the position is 
restricted by the manufacturer, test units in the manufacturer-specified 
position.
    3.1.3. Operate the integrated LED lamp at the rated voltage 
throughout testing. For an integrated LED lamp with multiple rated 
voltages including 120 volts, operate the lamp at 120 volts. If an 
integrated LED lamp with multiple rated voltages is not rated for 120 
volts, operate the lamp at the highest rated input voltage. Additional 
tests may be conducted at other rated voltages.
    3.1.4. Operate the lamp at the maximum input power. If multiple 
modes occur at the same maximum input power (such as variable CCT or 
CRI), the manufacturer can select any of these modes for testing; 
however, all measurements described in sections 3 and 4 of this appendix 
must be taken at the same selected mode. The test report must indicate 
which mode was selected for testing and include detail such that another 
laboratory could operate the lamp in the same mode.
    3.2. Test Method, Measurements, and Calculations
    3.2.1. The test conditions and setup described in section 3.1 of 
this appendix apply to this section 3.2.
    3.2.2. Stabilize the integrated LED lamp prior to measurement as 
specified in section 5.0 of IES LM-79-08 (incorporated by reference; see

LM-79-08. Do not use goniophotometers.
    3.2.8. Determine CRI according to the method specified in section 
12.0 of IES LM-79-08 with the exclusion of section 12.2 and 12.5 of IES 
LM-79-08. Do not use goniophotometers.
    3.2.9. Determine lamp efficacy by dividing measured initial lumen 
output by the measured input power.
    3.2.10. Determine power factor for AC-input lamps by dividing 
measured input power by the product of the measured input voltage and 
measured input current.

by dividing the interval lumen output ``xt'' by the initial 
lumen output ``x0''. Measure initial and interval lumen 
output in accordance with sections 4.2 and 4.5 of this appendix, 
respectively.
    4.6.2. For lumen maintenance values less than 0.7, including lamp

is equal to the previously recorded lumen output measurement (at a 
shorter test duration) where the lumen maintenance is greater than or 
equal to 0.7.
    4.6.3. For lumen maintenance values equal to 0.7, time to failure is 
equal to the test duration.
    4.6.4. For lumen maintenance values greater than 0.7, use the 
following method:
    4.6.4.1. For test duration values less than 3,000 hours, do not 
project time to failure. Time to failure equals the test duration.
    4.6.4.2. For test duration values greater than or equal to 3,000 
hours but less than 6,000 hours, time to failure is equal to the lesser 
of the projected time to failure calculated according to section 
4.6.4.2.1 of this appendix or the test duration multiplied by the 
limiting multiplier calculated in section 4.6.4.2.2 of this appendix.
    4.6.4.2.1. Project time to failure using the projection method 
described in section 5.1.4 of IES TM-28 (incorporated by reference; see 
Sec. 430.3). Project time to failure for each individual LED lamp. Do 
not use data obtained prior to a test duration value of 1,000 hours.
    4.6.4.2.2. Calculate the limiting multiplier from the following 
equation:

    4.6.4.3. For test duration values greater than 6,000 hours, time to 
failure is equal to the lesser of the projected time to failure 
calculated according to section 4.6.4.3.1 or the test duration 
multiplied by six.
    4.6.4.3.1. Project time to failure using the projection method 
described in section 5.1.4 of IES TM-28 (incorporated by reference; see 
Sec. 430.3). Project time to failure for each individual LED lamp. Data 
used for the time to failure projection method must be as specified in 
section 5.1.3 of IES TM-28.

     5. Standby Mode Test Method for Determining Standby Mode Power

    Measure standby mode power consumption for integrated LED lamps 
capable of operating in standby mode. The standby mode test method in 
this section 5 may be completed before or after the active mode test 
method for determining lumen output, input power, CCT, CRI, power 
factor, and lamp efficacy in section 3 of this appendix. The standby 
mode test method in this section 5 must be completed before the active 
mode test method for determining time to failure in section 4 of this 
appendix. In cases where there is a conflict, the language of the test 
procedure in this appendix takes precedence over IES LM-79 (incorporated 
by reference; see Sec. 430.3) and IEC 62301 (incorporated by reference; 
see Sec. 430.3).

                     5.1. Test Conditions and Setup

    5.1.1. Establish the ambient conditions, power supply, electrical 
settings, and instrumentation in accordance with the specifications in 
sections 2.0, 3.0, 7.0, and 8.0 of IES LM-79 (incorporated by reference; 
see Sec. 430.3),

[[Page 740]]

respectively. Maintain the ambient temperature at 25 [deg]C  1 [deg]C.
    5.1.2. Position a lamp in either the base-up and base-down 
orientation throughout testing. An equal number of lamps in the sample 
must be tested in the base-up and base-down orientations.
    5.1.3. Operate the integrated LED lamp at the rated voltage 
throughout testing. For an integrated LED lamp with multiple rated 
voltages, operate the integrated LED lamp at 120 volts. If an integrated 
LED lamp with multiple rated voltages is not rated for 120 volts, 
operate the integrated LED lamp at the highest rated input voltage.

            5.2. Test Method, Measurements, and Calculations

    5.2.1. The test conditions and setup described in section 3.1 of 
this appendix apply to this section.
    5.2.2. Connect the integrated LED lamp to the manufacturer-specified 
wireless control network (if applicable) and configure the integrated 
LED lamp in standby mode by sending a signal to the integrated LED lamp 
instructing it to have zero light output. Lamp must remain connected to 
the network throughout the duration of the test.
    5.2.3. Stabilize the integrated LED lamp as specified in section 5 
of IEC 62301 (incorporated by reference; see Sec. 430.3) prior to 
measurement.
    5.2.4. Measure the standby mode power in watts as specified in 
section 5 of IEC 62301.

               3. Test Apparatus and General Instructions

    3.1 Active mode.
    3.1.1 Test conduct. The test apparatus and instructions for testing 
portable air conditioners in cooling mode and off-cycle mode must 
conform to the requirements specified in Section 4, ``Definitions'' and 
Section 7, ``Tests,'' of ANSI/AHAM PAC-1-2015 (incorporated by 
reference; see Sec. 430.3), except as otherwise specified in this 
appendix. Where applicable, measure duct heat transfer and infiltration 
air heat transfer according to section 4.1.1.1 and section 4.1.1.2 of 
this appendix, respectively. Note that if a product is able to operate 
as both a single-duct and dual-duct portable AC as distributed in 
commerce by the manufacturer, it must be tested and rated for both duct 
configurations.
    3.1.1.1 Duct setup. Use ducting components provided by the 
manufacturer, including, where provided by the manufacturer, ducts, 
connectors for attaching the duct(s) to the test unit, sealing, 
insulation, and window mounting fixtures. Do not apply additional 
sealing or insulation.
    3.1.1.2 Single-duct evaporator inlet test conditions. When testing 
single-duct portable air conditioners, maintain the evaporator inlet 
dry-bulb temperature within a range of 1.0 [deg]F with an average 
difference within 0.3 [deg]F.
    3.1.1.3 Condensate Removal. Set up the test unit in accordance with 
manufacturer instructions. If the unit has an auto-evaporative feature, 
keep any provided drain plug installed as shipped and do not provide 
other means of condensate removal. If the internal condensate collection 
bucket fills during the test, halt the test, remove the drain plug, 
install a gravity drain line, and start the test from the beginning. If 
no auto-evaporative feature is available, remove the drain plug and 
install a gravity drain line. If no auto-evaporative feature or gravity 
drain is available and a condensate pump is included, or if the 
manufacturer specifies the use of an included condensate pump during 
cooling mode operation, then test the portable air conditioner with the 
condensate pump enabled. For units tested with a condensate pump, apply 
the provisions in Section 7.1.2 of ANSI/AHAM PAC-1-2015 (incorporated by 
reference; see Sec. 430.3) if the pump cycles on and off.
    3.1.1.4 Unit Placement. There shall be no less than 3 feet between 
any test chamber wall surface and any surface on the portable air 
conditioner, except the surface or surfaces of the portable air 
conditioner that include a duct attachment. The distance between the 
test chamber wall and a surface with one or more duct attachments is 
prescribed by the test setup requirements in Section 7.3.7 of ANSI/AHAM 
PAC-1-2015 (incorporated by reference; see Sec. 430.3).
    3.1.1.5 Electrical supply. Maintain the input standard voltage at 
115 V 1 percent. Test at the rated frequency, 
maintained within 1 percent.
    3.1.1.6 Duct temperature measurements. Install any insulation and 
sealing provided by the manufacturer. Then adhere four equally spaced 
thermocouples per duct to the outer surface of the entire length of the 
duct. Measure the surface temperatures of each duct. Temperature 
measurements must have an error no greater than 0.5 [deg]F over the range being measured.
    3.1.2 Control settings. Set the controls to the lowest available 
temperature setpoint for cooling mode. If the portable air conditioner 
has a user-adjustable fan speed, select the maximum fan speed setting. 
If the portable air conditioner has an automatic louver oscillation 
feature, disable that feature throughout testing. If the louver 
oscillation feature is included but there is no option to disable it, 
test with the louver oscillation enabled. If the portable air 
conditioner has adjustable louvers, position the louvers parallel with 
the air flow to maximize air flow and minimize static pressure loss.
    3.1.3 Measurement resolution. Record measurements at the resolution 
of the test instrumentation.
    3.2 Standby mode and off mode.
    3.2.1 Installation requirements. For the standby mode and off mode 
testing, install the portable air conditioner in accordance with Section 
5, Paragraph 5.2 of IEC 62301 (incorporated by reference; see Sec. 
430.3), disregarding the provisions regarding batteries and the 
determination, classification, and testing of relevant modes.
    3.2.2 Electrical energy supply.
    3.2.2.1 Electrical supply. For the standby mode and off mode 
testing, maintain the input standard voltage at 115 V 1 percent. Maintain the electrical supply at the rated 
frequency 1 percent.
    3.2.2.2 Supply voltage waveform. For the standby mode and off mode 
testing, maintain the electrical supply voltage waveform indicated in 
Section 4, Paragraph 4.3.2 of IEC 62301 (incorporated by reference; see 
Sec. 430.3).
    3.2.3 Standby mode and off mode wattmeter. The wattmeter used to 
measure standby mode and off mode power consumption must meet the 
requirements specified in Section 4, Paragraph 4.4 of IEC 62301 
(incorporated by reference; see Sec. 430.3).
    3.2.4 Standby mode and off mode ambient temperature. For standby 
mode and off mode testing, maintain room ambient air temperature 
conditions as specified in Section 4, Paragraph 4.2 of IEC 62301 
(incorporated by reference; see Sec. 430.3).

                           4. Test Measurement

    4.1 Cooling mode. Measure the indoor room cooling capacity and 
overall power input in cooling mode in accordance with Section

[[Page 742]]

7.1.b and 7.1.c of ANSI/AHAM PAC-1-2015 (incorporated by reference; see 
Sec. 430.3), respectively. Determine the test duration in accordance 
with Section 8.7 of ASHRAE Standard 37-2009 (incorporated by reference; 
Sec. 430.3). Apply the test conditions for single-duct and dual-duct 
portable air conditioners presented in Table 1 of this appendix instead 
of the test conditions in Table 3 of ANSI/AHAM PAC-1-2015. For single-
duct units, measure the indoor room cooling capacity, 
CapacitySD, and overall power input in cooling mode, 
PSD, in accordance with the ambient conditions for test 
configuration 5, presented in Table 1 of this appendix. For dual-duct 
units, measure the indoor room cooling capacity and overall power input 
in accordance with ambient conditions for test configuration 3, 
condition A (Capacity95, P95), and then measure 
the indoor room cooling capacity and overall power input a second time 
in accordance with the ambient conditions for test configuration 3, 
condition B (Capacity83, P83), presented in Table 
1 of this appendix. Note that for the purposes of this cooling mode test 
procedure, evaporator inlet air is considered the ``indoor air'' of the 
conditioned space and condenser inlet air is considered the ``outdoor 
air'' outside of the conditioned space.

          temperature for duct ``j'' of dual-duct portable air 
          conditioners, as measured during testing according to the two 
          outdoor test conditions in Table 1 of this appendix, in 
          [deg]F.

Qinfiltration_95 and Qinfiltration_83 = total 
          infiltration air heat in cooling mode, calculated at the 95 
          [deg]F and 83 [deg]F dry-bulb outdoor conditions in Table 1 of 
          this appendix, in Btu/h.
Qs_95 and Qs_83 = sensible heat added to the room 
          by infiltration air, calculated at the 95 [deg]F and 83 [deg]F 
          dry-bulb outdoor conditions in Table 1 of this appendix, in 
          Btu/h.
Ql_95 and Ql_83 = latent heat added to the room by 
          infiltration air, calculated at the 95 [deg]F and 83 [deg]F 
          dry-bulb outdoor conditions in Table 1 of this appendix, in 
          Btu/h.
4.2 Off-cycle mode. Establish the test conditions specified in section 
          3.1.1 of this appendix for off-cycle mode and use the 
          wattmeter specified in section 3.2.3 of this appendix (but do 
          not use the duct measurements in section 3.1.1.6). Begin the 
          off-cycle mode test period 5 minutes following the cooling 
          mode test period. Adjust the setpoint higher than the ambient 
          temperature to ensure the product will not enter cooling mode 
          and begin the test 5 minutes after the compressor cycles off 
          due to the change in setpoint. Do not change any other control 
          settings between the end of the cooling mode test period and 
          the start of the off-cycle mode test period. The off-cycle 
          mode test period must be 2 hours in duration, during which 
          period, record the power consumption at the same intervals as 
          recorded for cooling mode testing. Measure and record the 
          average off-cycle mode power of the portable air conditioner, 
          Poc, in watts.
    4.3 Standby mode and off mode. Establish the testing conditions set 
forth in section 3.2 of this appendix, ensuring that the portable air 
conditioner does not enter any active modes during the test. For 
portable air conditioners that take some time to enter a stable state 
from a higher power state as discussed in Section 5, Paragraph 5.1, Note 
1 of IEC 62301, (incorporated by reference; see Sec. 430.3), allow 
sufficient time for the portable air conditioner to reach the lowest 
power state before proceeding with the test measurement. Follow the test 
procedure specified in Section 5, Paragraph 5.3.2 of IEC 62301 for 
testing in each possible mode as described in sections 4.3.1 and 4.3.2 
of this appendix.
    4.3.1 If the portable air conditioner has an inactive mode, as 
defined in section 2.6 of this appendix, but not an off mode, as defined 
in section 2.8 of this appendix, measure and record the average inactive 
mode power of the portable air conditioner, Pia, in watts.
    4.3.2 If the portable air conditioner has an off mode, as defined in 
section 2.8 of this appendix, measure and record the average off mode 
power of the portable air conditioner, Pom, in watts.

        5. Calculation of Derived Results From Test Measurements

    5.1 Adjusted Cooling Capacity. Calculate the adjusted cooling 
capacities for portable air conditioners, ACC95 and 
ACC83, expressed in Btu/h, according to the following 
equations. For single-duct portable air conditioners:

ACC95 = CapacitySD - Qduct_SD - 
          Qinfiltration_95
ACC83 = CapacitySD - Qduct_SD - 
          Qinfiltration_83

    For dual-duct portable air conditioners:
ACC95 = Capacity95 - Qduct_95 - 
          Qinfiltration_95
ACC83 = Capacity83 - Qduct_83 - 
          Qinfiltration_83

Where:

CapacitySD, Capacity95, and Capacity83 
          = cooling capacity measured in section 4.1.1 of this appendix.
Qduct_SD, Qduct_95, and Qduct_83 = duct 
          heat transfer while operating in cooling mode, calculated in 
          section 4.1.1.1 of this appendix.
Qinfiltration_95 and Qinfiltration_83 = total 
          infiltration air heat transfer in cooling mode, calculated in 
          section 4.1.1.2 of this appendix.

    5.2 Seasonally Adjusted Cooling Capacity. Calculate the seasonally 
adjusted cooling capacity for portable air conditioners, SACC, expressed 
in Btu/h, according to:

SACC = ACC95 x 0.2 + ACC83 x 0.8

Where:

ACC95 and ACC83 = adjusted cooling capacity, in 
          Btu/h, calculated in section 5.1 of this appendix.

  annual energy consumption under different ambient conditions for dual-
  duct portable air conditioners, and are not a division of the total
  cooling mode operating hours. The total dual-duct cooling mode
  operating hours are 750 hours.

AECm = Pm x tm x k

          year.
    m represents the operating modes included in AECT (``oc'' 
off-cycle, and ``im'' inactive or ``om'' off mode).

    5.4 Combined Energy Efficiency Ratio. Using the annual operating 
hours, as outlined in section 5.3 of this appendix, calculate the 
combined energy efficiency ratio, CEER, expressed in Btu/Wh, according 
to the following:

          tested at the 95 [deg]F and 83 [deg]F dry-bulb outdoor 
          conditions in Table 1 of this appendix, in Btu/h, calculated 
          in section 5.1 of this appendix.

   Sec. Appendix DD to Subpart B of Part 430--Uniform Test Method for 
   Measuring the Energy Consumption and Energy Efficiency of General 
 Service Lamps That Are Not General Service Incandescent Lamps,
 Compact Fluorescent Lamps, or Integrated LED Lamps

    Note: On or after April 19, 2017, any representations, including 
certifications of compliance (if required), made with respect to the 
energy use or efficiency of general service lamps that are not general 
service incandescent lamps, compact fluorescent lamps, or integrated LED 
lamps must be made in accordance with the results of testing pursuant to 
this appendix DD.
    1. Scope: This appendix DD specifies the test methods required to 
measure the initial lumen output, input power, lamp efficacy, power 
factor, and standby mode energy consumption of general service lamps 
that are not general service incandescent lamps, compact fluorescent 
lamps, or integrated LED lamps.
    2. Definitions:
    Measured initial input power means the input power to the lamp, 
measured after the lamp is stabilized and seasoned (if applicable), and 
expressed in watts (W).
    Measured initial lumen output means the lumen output of the lamp, 
measured after the lamp is stabilized and seasoned (if applicable), and 
expressed in lumens (lm).
    Power factor means the measured initial input power (watts) divided 
by the product of the input voltage (volts) and the input current (amps) 
measured at the same time as the initial input power.
    3. Active Mode Test Procedures
    3.1. Take measurements at full light output.
    3.2. Do not use a goniophotometer.
    3.3. For single base OLED and non-integrated LED lamps, position a 
lamp in either the base-up and base-down orientation throughout testing. 
Test an equal number of lamps in the sample in the base-up and base-down 
orientations, except that, if the manufacturer restricts the 
orientation, test all of the units in the sample in the manufacturer-
specified orientation. For double base OLED and non-integrated LED 
lamps, test all units in the horizontal orientation except that, if the 
manufacturer restricts the orientation, test all of the units in the 
sample in the manufacturer-specified orientation.
    3.4. Operate the lamp at the rated voltage throughout testing. For 
lamps with multiple rated voltages including 120 volts, operate the lamp 
at 120 volts. If a lamp is not rated for 120 volts, operate the lamp at 
the highest rated input voltage. For non-integrated LED lamps, operate 
the lamp at the manufacturer-declared input voltage and current.
    3.5. Operate the lamp at the maximum input power. If multiple modes 
occur at the same maximum input power (such as variable CCT or CRI), the 
manufacturer may select any of these modes for testing; however, all 
measurements must be taken at the same selected mode. The manufacturer 
must indicate in the test report which mode was selected for testing and 
include detail such that another laboratory could operate the lamp in 
the same mode.
    3.6. To measure initial lumen output, input power, input voltage, 
and input current use the test procedures in the table in this section.

    (iv) Automatic means for adjusting water temperature. (A) The 
automatic means for adjusting water temperature as required under 
paragraph (e)(2)(ii) of this section must automatically adjust the 
temperature of the water supplied by the boiler to ensure that an 
incremental change in inferred heat load produces a corresponding 
incremental change in the temperature of water supplied.
    (B) For boilers that fire at a single input rate, the automatic 
means for adjusting water temperature requirement may be satisfied by 
providing an automatic means that allows the burner or heating element 
to fire only when the means has determined that the inferred heat load 
cannot be met by the residual heat of the water in the system.
    (C) When there is no inferred heat load with respect to a hot water 
boiler, the automatic means described in this paragraph shall limit the 
temperature of the water in the boiler to not more than 140 degrees 
Fahrenheit.

                              1. Objectives

    This appendix establishes procedures, interpretations and policies 
to guide the DOE in the consideration and promulgation of new or revised 
appliance efficiency standards under the Energy Policy and Conservation 
Act (EPCA). The Department's objectives in establishing these guidelines 
include:
    (a) Provide for early input from stakeholders. The Department seeks 
to provide opportunities for public input early in the rulemaking 
process so that the initiation and direction of rulemakings is informed 
by comment from interested parties. Under the guidelines established by 
this appendix, DOE will seek early input from interested parties in 
setting rulemaking priorities and structuring the analyses for 
particular products. Interested parties will be invited to provide input 
for the selection of design options and will help DOE identify analysis, 
data, and modeling needs. DOE will gather input from interested parties 
through a variety of mechanisms, including public workshops.
    (b) Increase predictability of the rulemaking timetable. The 
Department seeks to make informed, strategic decisions about how to 
deploy its resources on the range of possible standards development 
activities, and to announce these prioritization decisions so that all 
interested parties have a common expectation about the timing of 
different rulemaking activities. The guidelines in this appendix provide 
for setting priorities and timetables for standards development and test 
procedure modification and reflect these priorities in the Regulatory 
Agenda.
    (c) Increase use of outside technical expertise. The Department 
seeks to expand its use of outside technical experts in evaluating 
product-specific engineering issues to ensure that decisions on 
technical issues are fully informed. The guidelines in this appendix 
provide for increased use of outside technical experts in developing, 
performing and reviewing the analyses. Draft analytical results will be 
distributed for peer and stakeholder review.
    (d) Eliminate problematic design options early in the process. The 
Department seeks to eliminate from consideration, early in the process, 
any design options that present unacceptable problems with respect to 
manufacturability, consumer utility, or safety, so that the detailed 
analysis can focus only on viable design options. Under the

[[Page 769]]

guidelines in this appendix, DOE will eliminate from consideration 
design options if it concludes that manufacture, installation or service 
of the design will be impractical, or that the design option will 
adversely affect the utility of the product, or if the design has 
adverse safety or health impacts. This screening will be done at the 
outset of a rulemaking.
    (e) Fully consider non-regulatory approaches. The Department seeks 
to understand the effects of market forces and voluntary programs on 
encouraging the purchase of energy efficient products so that the 
incremental impacts of a new or revised standard can be accurately 
assessed and the Department can make informed decisions about where 
standards and voluntary ``market pull'' programs can be used most 
effectively. Under the guidelines in this appendix, DOE will solicit 
information on the effectiveness of market forces and non-regulatory 
approaches for encouraging the purchase of energy efficient products, 
and will carefully consider this information in assessing the benefits 
of standards. In addition, DOE will continue to support voluntary 
efforts by manufacturers, retailers, utilities and others to increase 
product efficiency.
    (f) Conduct thorough analysis of impacts. In addition to 
understanding the aggregate costs and benefits of standards, the 
Department seeks to understand the distribution of those costs and 
benefits among consumers, manufacturers and others, and the uncertainty 
associated with these analyses of costs and benefits, so that any 
adverse impacts on significant subgroups and uncertainty concerning any 
adverse impacts can be fully considered in selecting a standard. Under 
the guidelines in this appendix, the analyses will consider the 
variability of impacts on significant groups of manufacturers and 
consumers in addition to aggregate costs and benefits, report the range 
of uncertainty associated with these impacts, and take into account 
cumulative impacts of regulation on manufacturers.
    (g) Use transparent and robust analytical methods. The Department 
seeks to use qualitative and quantitative analytical methods that are 
fully documented for the public and that produce results that can be 
explained and reproduced, so that the analytical underpinnings for 
policy decisions on standards are as sound and well-accepted as 
possible. Under the guidelines in this appendix, DOE will solicit input 
from interested parties in identifying analysis, data, and modeling 
needs with respect to measurement of impacts on manufacturers and 
consumers.
    (h) Articulate policies to guide selection of standards. The 
Department seeks to adopt policies elaborating on the statutory criteria 
for selecting standards, so that interested parties are aware of the 
policies that will guide these decisions. Under the guidelines in this 
appendix, policies for screening design options, selecting candidate 
standard levels, selecting a proposed standard level, and establishing 
the final standard are established.
    (i) Support efforts to build consensus on standards. The Department 
seeks to encourage development of consensus proposals for new or revised 
standards because standards with such broad-based support are likely to 
balance effectively the economic, energy, and environmental interests 
affected by standards. Under the guidelines in this appendix, DOE will 
support the development and submission of consensus recommendations for 
standards by representative groups of interested parties to the fullest 
extent possible.
    (j) Reduce time and cost of developing standards. The Department 
seeks to establish a clear protocol for initiating and conducting 
standards rulemakings in order to eliminate time-consuming and costly 
missteps. Under the guidelines in this appendix, increased and earlier 
involvement by interested parties and increased use of technical experts 
should minimize the need for re-analysis. This process should reduce the 
period between the publication of an Advance Notice of Proposed 
Rulemaking (ANOPR) and the publication of a final rule to not more than 
18 months, and should decrease the government and private sector 
resources required to complete the standard development process.

                                2. Scope

    (a) The procedures, interpretations and policies described in this 
appendix will be fully applicable to:
    (1) Rulemakings concerning new or revised Federal energy 
conservation standards for consumer products initiated after August 14, 
1996, and
    (2) Rulemakings concerning new or revised Federal energy 
conservation standards for consumer products that have been initiated 
but for which a Notice of Proposed Rulemaking (NOPR) has not been 
published as of August 14, 1996.
    (b) For rulemakings described in paragraph (a)(2) of this section, 
to the extent analytical work has already been done or public comment on 
an ANOPR has already been provided, such analyses and comment will be 
considered, as appropriate, in proceeding under the new process.
    (c) With respect to incomplete rulemakings concerning new or revised 
Federal energy conservation standards for consumer products for which a 
NOPR was published prior to August 14, 1996, the Department will conduct 
a case-by-case review to decide whether any of the analytical or 
procedural steps already completed should be repeated. In any case, the 
approach described in this appendix will be used to the extent

[[Page 770]]

possible to conduct any analytical or procedural steps that have not 
been completed.

              3. Setting Priorities for Rulemaking Activity

    (a) Priority-setting analysis and development of list of priorities. 
At least once a year, the Department will prepare an analysis of each of 
the factors identified in paragraph (d) of this section based on 
existing literature, direct communications with interested parties and 
other experts, and other available information. The results of this 
analysis will be used to develop rulemaking priorities and proposed 
schedules for the development and issuance of all rulemakings. The DOE 
analysis, priorities and proposed rulemaking schedules will be 
documented and distributed for review and comment.
    (b) Public review and comment. Each year, DOE will invite public 
input to review and comment on the priority analysis.
    (c) Issuance of final listing of rulemaking priorities. Each fall, 
the Department will issue, simultaneously with the issuance of the 
Administration's Regulatory Agenda, a final set of rulemaking 
priorities, the accompanying analysis, and the schedules for all 
priority rulemakings that it anticipates within the next two years.
    (d) Factors for priority-setting. The factors to be considered by 
DOE in developing priorities and establishing schedules for conducting 
rulemakings will include:
    (1) Potential energy savings.
    (2) Potential economic benefits.
    (3) Potential environmental or energy security benefits.
    (4) Applicable deadlines for rulemakings.
    (5) Incremental DOE resources required to complete rulemaking 
process.
    (6) Other relevant regulatory actions affecting products.
    (7) Stakeholder recommendations.
    (8) Evidence of energy efficiency gains in the market absent new or 
revised standards.
    (9) Status of required changes to test procedures.
    (10) Other relevant factors.

    4. Process for Developing Efficiency Standards and Factors to be 
                               Considered

    This section describes the process to be used in developing 
efficiency standards and the factors to be considered in the process. 
The policies of the Department to guide the selection of standards and 
the decisions preliminary thereto are described in section 5.
    (a) Identifying and screening design options. Once the Department 
has initiated a rulemaking for a specific product but before publishing 
an ANOPR, DOE will identify the product categories and design options to 
be analyzed in detail, and identify those design options eliminated from 
further consideration. Interested parties will be consulted to identify 
key issues, develop a list of design options, and to help the Department 
identify the expertise necessary to conduct the analysis.
    (1) Identification of issues for analysis. The Department, in 
consultation with interested parties, will identify issues that will be 
examined in the standards development process.
    (2) Identification of experts and other interested parties for peer 
review. DOE, in consultation with interested parties, will identify a 
group of independent experts and other interested parties who can 
provide expert review of the results of the engineering analysis and the 
subsequent impact analysis.
    (3) Identification and screening of design options. In consultation 
with interested parties, the Department will develop a list of design 
options for consideration. Initially, the candidate design options will 
encompass all those technologies considered to be technologically 
feasible. Following the development of this initial list of design 
options, DOE will review each design option based on the factors 
described in paragraph (a)(4) of this section and the policies stated in 
section 5(b). The reasons for eliminating any design option at this 
stage of the process will be fully documented and published as part of 
the ANOPR. The technologically feasible design options that are not 
eliminated in this screening will be considered further in the 
Engineering Analysis described in paragraph (b) of this section.
    (4) Factors for screening of design options. The factors for 
screening design options include:
    (i) Technological feasibility. Technologies incorporated in 
commercial products or in working prototypes will be considered 
technologically feasible.
    (ii) Practicability to manufacture, install and service. If mass 
production of a technology in commercial products and reliable 
installation and servicing of the technology could be achieved on the 
scale necessary to serve the relevant market at the time of the 
effective date of the standard, then that technology will be considered 
practicable to manufacture, install and service.
    (iii) Adverse Impacts on Product Utility or Product Availability.
    (iv) Adverse Impacts on Health or Safety.
    (5) Selection of contractors. Using the specifications of necessary 
contractor expertise developed in consultation with interested parties, 
DOE will select appropriate contractors, subcontractors, and as 
necessary, expert consultants to perform the engineering analysis and 
the impact analysis.
    (b) Engineering analysis of design options and selection of 
candidate standard levels. After design options are identified and 
screened, DOE will perform the engineering analysis and

[[Page 771]]

the benefit/cost analysis and select the candidate standard levels based 
on these analyses. The results of the analyses will be published in a 
Technical Support Document (TSD) to accompany the ANOPR.
    (1) Identification of engineering analytical methods and tools. DOE, 
in consultation with outside experts, will select the specific 
engineering analysis tools (or multiple tools, if necessary to address 
uncertainty) to be used in the analysis of the design options identified 
as a result of the screening analysis.
    (2) Engineering and life-cycle cost analysis of design options. The 
DOE and its contractor will perform engineering and life-cycle cost 
analyses of the design options.
    (3) Review by expert group and stakeholders. The results of the 
engineering and life-cycle cost analyses will be distributed for review 
by experts and interested parties. If appropriate, a public workshop 
will be conducted to review these results. The analyses will be revised 
as appropriate on the basis of this input.
    (4) New information relating to the factors used for screening 
design options. If further information or analysis leads to a 
determination that a design option, or a combination of design options, 
has unacceptable impacts based on the policies stated in section 5(b), 
that design option or combination of design options will not be included 
in a candidate standard level.
    (5) Selection of candidate standard levels. Based on the results of 
the engineering and life-cycle cost analysis of design options and the 
policies stated in section 5(c), DOE will select the candidate standard 
levels for further analysis.
    (c) Advance Notice of Proposed Rulemaking--(1) Documentation of 
decisions on candidate standard selection. (i) If the screening analysis 
indicates that continued development of a standard is appropriate, the 
Department will publish an ANOPR in the Federal Register and will 
distribute a draft TSD containing the analyses performed to this point. 
The ANOPR will specify candidate standard levels but will not propose a 
particular standard. The ANOPR will also include the preliminary 
analysis of consumer life-cycle costs, national net present value, and 
energy impacts for the candidate standard levels based on the 
engineering analysis.
    (ii) If the preliminary analysis indicates that no candidate 
standard level is likely to meet the criteria specified in law, that 
conclusion will be announced. In such cases, the Department may decide 
to proceed with a rulemaking that proposes not to adopt new or amended 
standards, or it may suspend the rulemaking and conclude that further 
action on such standards should be assigned a low priority under section 
3.
    (2) Public comment and hearing. There will be 75 days for public 
comment on the ANOPR with at least one public hearing or workshop.
    (3) Revisions based on comments. Based on consideration of the 
comments received, any necessary changes to the engineering analysis or 
the candidate standard levels will be made.
    If major changes are required at this stage, interested parties and 
experts will be given an opportunity to review the revised analysis.
    (d) Analysis of impacts and selection of proposed standard level. 
After the ANOPR, economic analyses of the impacts of the candidate 
standard levels will be conducted. The Department will propose updated 
standards based on the results of the impact analysis.
    (1) Identification of issues for analysis. The Department, in 
consultation with interested parties, will identify issues that will be 
examined in the impacts analysis.
    (2) Identification of analytical methods and tools. DOE, in 
consultation with outside experts, will select the specific economic 
analysis tools (or multiple tools if necessary to address uncertainty) 
to be used in the analysis of the candidate standard levels.
    (3) Analysis of impacts. DOE will conduct the analysis of the 
impacts of candidate standard levels including analysis of the factors 
described in paragraphs (d)(7)(ii)-(viii) of this section.
    (4) Review by expert group and stakeholders. The results of the 
analysis of impacts will be distributed for review by experts and 
interested parties. If appropriate, a public workshop will be conducted 
to review these results. The analysis will be revised as appropriate on 
the basis of this input.
    (5) Efforts to develop consensus among stakeholders. If a 
representative group of interested parties undertakes to develop joint 
recommendations to the Department on standards, DOE will consider 
deferring its impact analysis until these discussions are completed or 
until participants in the efforts indicate that they are unable to reach 
a timely agreement.
    (6) Selection of proposed standard level based on analysis of 
impacts. On the basis of the analysis of the factors described in 
paragraph (d)(7) of this section and the policies stated in section 
5(e), DOE will select a proposed standard level.
    (7) Factors to be considered in selecting a proposed standard. The 
factors to be considered in selection of a proposed standard include:
    (i) Consensus stakeholder recommendations.
    (ii) Impacts on manufacturers. The analysis of manufacturer impacts 
will include: Estimated impacts on cash flow; assessment of impacts on 
manufacturers of specific categories of products and small 
manufacturers; assessment of impacts on manufacturers of multiple 
product-specific Federal regulatory requirements, including efficiency 
standards

[[Page 772]]

for other products and regulations of other agencies; and impact on 
manufacturing capacity, plant closures, and loss of capital investment.
    (iii) Impacts on consumers. The analysis of consumer impacts will 
include: Estimated impacts on consumers based on national average energy 
prices and energy usage; assessments of impacts on subgroups of 
consumers based on major regional differences in usage or energy prices 
and significant variations in installation costs or performance; 
sensitivity analyses using high and low discount rates and high and low 
energy price forecasts; consideration of changes to product utility and 
other impacts of likely concern to all or some consumers, based to the 
extent practicable on direct input from consumers; estimated life-cycle 
cost with sensitivity analysis; and consideration of the increased first 
cost to consumers and the time required for energy cost savings to pay 
back these first costs.
    (iv) Impacts on competition.
    (v) Impacts on utilities. The analysis of utility impacts will 
include estimated marginal impacts on electric and gas utility costs and 
revenues.
    (vi) National energy, economic and employment impacts. The analysis 
of national energy, economic and employment impacts will include: 
Estimated energy savings by fuel type; estimated net present value of 
benefits to all consumers; and estimates of the direct and indirect 
impacts on employment by appliance manufacturers, relevant service 
industries, energy suppliers and the economy in general.
    (vii) Impacts on the environment and energy security. The analysis 
of environmental and energy security impacts will include estimated 
impacts on emissions of carbon and relevant criteria pollutants, impacts 
on pollution control costs, and impacts on oil use.
    (viii) Impacts of non-regulatory approaches. The analysis of energy 
savings and consumer impacts will incorporate an assessment of the 
impacts of market forces and existing voluntary programs in promoting 
product efficiency, usage and related characteristics in the absence of 
updated efficiency standards.
    (ix) New information relating to the factors used for screening 
design options.
    (e) Notice of Proposed Rulemaking--(1) Documentation of decisions on 
proposed standard selection. The Department will publish a NOPR in the 
Federal Register that proposes standard levels and explains the basis 
for the selection of those proposed levels, and will distribute a draft 
TSD documenting the analysis of impacts. As required by Sec. 325(p)(2) 
of EPCA, the NOPR also will describe the maximum improvement in energy 
efficiency or maximum reduction in energy use that is technologically 
feasible and, if the proposed standards would not achieve these levels, 
the reasons for proposing different standards.
    (2) Public comment and hearing. There will be 75 days for public 
comment on the NOPR, with at least one public hearing or workshop.
    (3) Revisions to impact analyses and selection of final standard. 
Based on the public comments received and the policies stated in section 
5(f), DOE will review the proposed standard and impact analyses, and 
make modifications as necessary. If major changes to the analyses are 
required at this stage, interested parties and experts will be given an 
opportunity to review the revised analyses.
    (f) Notice of Final Rulemaking. The Department will publish a Notice 
of Final Rulemaking in the Federal Register that promulgates standard 
levels and explains the basis for the selection of those standards, 
accompanied by a final TSD.

                 5. Policies on Selection of Standards.

    (a) Purpose. (1) Section 4 describes the process that will be used 
to consider new or revised energy efficiency standards and lists a 
number of factors and analyses that will be considered at specified 
points in the process. Department policies co12467ncerning the selection 
of new or revised standards, and decisions preliminary thereto, are 
described in this section.
    These policies are intended to elaborate on the statutory criteria 
provided in section 325 of the EPCA, 42 U.S.C. 6295.
    (2) The policies described below are intended to provide guidance 
for making the determinations required by EPCA. This statement of policy 
is not intended to preclude consideration of any information pertinent 
to the statutory criteria. The Department will consider all pertinent 
information in determining whether a new or revised standard is 
consistent with the statutory criteria. Moreover, the Department will 
not be guided by a policy in this section if, in the particular 
circumstances presented, such a policy would lead to a result 
inconsistent with the criteria in section 325 of EPCA.
    (b) Screening design options. Section 4(a)(4) lists factors to be 
considered in screening design options. These factors will be considered 
as follows in determining whether a design option will receive any 
further consideration:
    (1) Technological feasibility. Technologies that are not 
incorporated in commercial products or in working prototypes will not be 
considered further.
    (2) Practicability to manufacture, install and service. If it is 
determined that mass production of a technology in commercial products 
and reliable installation and servicing of the technology could not be 
achieved on the scale necessary to serve the relevant market

[[Page 773]]

at the time of the effective date of the standard, then that technology 
will not be considered further.
    (3) Impacts on product utility to consumers. If a technology is 
determined to have significant adverse impact on the utility of the 
product to significant subgroups of consumers, or result in the 
unavailability of any covered product type with performance 
characteristics (including reliability), features, sizes, capacities, 
and volumes that are substantially the same as products generally 
available in the U.S. at the time, it will not be considered further.
    (4) Safety of technologies. If it is determined that a technology 
will have significant adverse impacts on health or safety, it will not 
be considered further.
    (c) Identification of candidate standard levels. Based on the 
results of the engineering and cost and benefit analyses of design 
options, DOE will identify the candidate standard levels for further 
analysis. Candidate standard levels will be selected as follows:
    (1) Costs and savings of design options. Design options which have 
payback periods that exceed the average life of the product or which 
cause life-cycle cost increases relative to the base case, using typical 
fuel costs, usage and discount rates, will not be used as the basis for 
candidate standard levels.
    (2) Further information on factors used for screening design 
options. If further information or analysis leads to a determination 
that a design option, or a combination of design options, has 
unacceptable impacts under the policies stated in paragraph (b) of this 
section, that design option or combination of design options will not be 
included in a candidate standard level.
    (3) Selection of candidate standard levels. Candidate standard 
levels, which will be identified in the ANOPR and on which impact 
analyses will be conducted, will be based on the remaining design 
options.
    (i) The range of candidate standard levels will typically include:
    (A) The most energy efficient combination of design options;
    (B) The combination of design options with the lowest life-cycle 
cost; and
    (C) A combination of design options with a payback period of not 
more than three years.
    (ii) Candidate standard levels that incorporate noteworthy 
technologies or fill in large gaps between efficiency levels of other 
candidate standard levels also may be selected.
    (d) Advance notice of proposed rulemaking. New information provided 
in public comments on the ANOPR will be considered to determine whether 
any changes to the candidate standard levels are needed before 
proceeding to the analysis of impacts. This review, and any appropriate 
adjustments, will be based on the policies in paragraph (c) of this 
section.
    (e) Selection of proposed standard. Based on the results of the 
analysis of impacts, DOE will select a standard level to be proposed for 
public comment in the NOPR. Section 4(d)(7) lists the factors to be 
considered in selecting a proposed standard level. Section 325(o)(2)(A) 
of EPCA provides that any new or revised standard must be designed to 
achieve the maximum improvement in energy efficiency that is determined 
to be technologically feasible and economically justified.
    (1) Statutory policies. The fundamental policies concerning 
selection of standards are established in the EPCA, including the 
following:
    (i) A candidate standard level will not be proposed or promulgated 
if the Department determines that it is not technologically feasible and 
economically justified. See EPCA section 325(o)(3)(B). A standard level 
is economically justified if the benefits exceed the burdens. See EPCA 
section 325(o)(2)(B)(i). A standard level is rebuttably presumed to be 
economically justified if the payback period is three years or less. See 
EPCA section 325(o)(2)(B)(iii).
    (ii) If the Department determines that a standard level is likely to 
result in the unavailability of any covered product type with 
performance characteristics (including reliability), features, sizes, 
capacities, and volumes that are substantially the same as products 
generally available in the U.S. at the time, that standard level will 
not be proposed. See EPCA section 325(o)(4).
    (iii) If the Department determines that a standard level would not 
result in significant conservation of energy, that standard level will 
not be proposed. See EPCA section 325(o)(3)(B).
    (2) Selection of proposed standard on the basis of consensus 
stakeholder recommendations. Development of consensus proposals for new 
or revised standards is an effective mechanism for balancing the 
economic, energy, and environmental interests affected by standards. 
Thus, notwithstanding any other policy on selection of proposed 
standards, a consensus recommendation on an updated efficiency level 
submitted by a group that represents all interested parties will be 
proposed by the Department if it is determined to meet the statutory 
criteria.
    (3) Considerations in assessing economic justification.
    (i) The following policies will guide the application of the 
economic justification criterion in selecting a proposed standard:
    (A) If the Department determines that a candidate standard level 
would result in a negative return on investment for the industry, would 
significantly reduce the value of the industry, or would cause 
significant adverse impacts to a significant subgroup of manufacturers 
(including small manufacturing businesses), that standard level will

[[Page 774]]

be presumed not to be economically justified unless the Department 
determines that specifically identified expected benefits of the 
standard would outweigh this and any other expected adverse effects.
    (B) If the Department determines that a candidate standard level 
would be the direct cause of plant closures, significant losses in 
domestic manufacturer employment, or significant losses of capital 
investment by domestic manufacturers, that standard level will be 
presumed not to be economically justified unless the Department 
determines that specifically identified expected benefits of the 
standard would outweigh this and any other expected adverse effects.
    (C) If the Department determines that a candidate standard level 
would have a significant adverse impact on the environment or energy 
security, that standard level will be presumed not to be economically 
justified unless the Department determines that specifically identified 
expected benefits of the standard would outweigh this and any other 
expected adverse effects.
    (D) If the Department determines that a candidate standard level 
would not result in significant energy conservation relative to non-
regulatory approaches, that standard level will be presumed not to be 
economically justified unless the Department determines that other 
specifically identified expected benefits of the standard would outweigh 
the expected adverse effects.
    (E) If the Department determines that a candidate standard level is 
not consistent with the policies relating to practicability to 
manufacture, consumer utility, or safety in paragraphs (b) (2), (3) and 
(4) of this section, that standard level will be presumed not to be 
economically justified unless the Department determines that 
specifically identified expected benefits of the standard would outweigh 
this and any other expected adverse effects.
    (F) If the Department determines that a candidate standard level is 
not consistent with the policies relating to consumer costs in paragraph 
(c)(1) of this section, that standard level will be presumed not to be 
economically justified unless the Department determines that 
specifically identified expected benefits of the standard would outweigh 
this and any other expected adverse effects.
    (G) If the Department determines that a candidate standard level 
will have significant adverse impacts on a significant subgroup of 
consumers (including low-income consumers), that standard level will be 
presumed not to be economically justified unless the Department 
determines that specifically identified expected benefits of the 
standard would outweigh this and any other expected adverse effects.
    (H) If the Department or the Department of Justice determines that a 
candidate standard level would have significant anticompetitive effects, 
that standard level will be presumed not to be economically justified 
unless the Department determines that specifically identified expected 
benefits of the standard would outweigh this and any other expected 
adverse effects.
    (ii) The basis for a determination that triggers any presumption in 
paragraph (e)(3)(i) of this section and the basis for a determination 
that an applicable presumption has been rebutted will be supported by 
substantial evidence in the record and the evidence and rationale for 
making these determinations will be explained in the NOPR.
    (iii) If none of the policies in paragraph (e)(3)(i) of this section 
is found to be dispositive, the Department will determine whether the 
benefits of a candidate standard level exceed the burdens considering 
all the pertinent information in the record.
    (f) Selection of a final standard. New information provided in the 
public comments on the NOPR and any analysis by the Department of 
Justice concerning impacts on competition of the proposed standard will 
be considered to determine whether any change to the proposed standard 
level is needed before proceeding to the final rule. The same policies 
used to select the proposed standard level, as described in section 5(e) 
above, will be used to guide the selection of the final standard level.

                     6. Effective Date of a Standard

    The effective date for new or revised standards will be established 
so that the period between the publication of the final rule and the 
effective date is not less than any period between the dates for 
publication and effective date provided for in EPCA. The effective date 
of any revised standard will be established so that the period between 
the effective date of the prior standard and the effective date of such 
revised standard is not less than period between the two effective dates 
provided for in EPCA.

                           7. Test Procedures

    (a) Identifying the need to modify test procedures. DOE, in 
consultation with interested parties, experts, and the National 
Institute of Standards and Technology, will attempt to identify any 
necessary modifications to established test procedures when initiating 
the standards development process.
    (b) Developing and proposing revised test procedures. Needed 
modifications to test procedures will be identified in consultation with 
experts and interested parties early in the screening stage of the 
standards development process. Any necessary modifications will be 
proposed before issuance of an ANOPR in the standards development 
process.

[[Page 775]]

    (c) Issuing final test procedure modification. Final, modified test 
procedures will be issued prior to the NOPR on proposed standards.
    (d) Effective date of modified test procedures. If required only for 
the evaluation and issuance of updated efficiency standards, modified 
test procedures typically will not go into effect until the effective 
date of updated standards.

                  8. Joint Stakeholder Recommendations

    (a) Joint recommendations. Consensus recommendations, and supporting 
analyses, submitted by a representative group of interested parties will 
be given substantial weight by DOE in the development of a proposed 
rule. See section 5(e)(2). If the supporting analyses provided by the 
group addresses all of the statutory criteria and uses valid economic 
assumptions and analytical methods, DOE expects to use this supporting 
analyses as the basis of a proposed rule. The proposed rule will explain 
any deviations from the consensus recommendations from interested 
parties.
    (b) Breadth of participation. Joint recommendations will be of most 
value to the Department if the participants are reasonably 
representative of those interested in the outcome of the standards 
development process, including manufacturers, consumers, utilities, 
states and representatives of environmental or energy efficiency 
interest groups.
    (c) DOE support of consensus development, including impact analyses. 
In order to facilitate such consensus development, DOE will make 
available, upon request, appropriate technical and legal support to the 
group and will provide copies of all relevant public documents and 
analyses. The Department also will consider any requests for its active 
participation in such discussions, recognizing that the procedural 
requirements of the Federal Advisory Committee Act may apply to such 
participation.

          9. Principles for the Conduct of Engineering Analysis

    (a) The purpose of the engineering analysis is to develop the 
relationship between efficiency and cost of the subject product. The 
Department will use the most appropriate means available to determine 
the efficiency/cost relationship, including an overall system approach 
or engineering modeling to predict the improvement in efficiency that 
can be expected from individual design options as discussed in the 
paragraphs below. From this efficiency/cost relationship, measures such 
as payback, life cycle cost, and energy savings can be developed. The 
Department, in consultation with interested parties, will identify 
issues that will be examined in the engineering analysis and the types 
of specialized expertise that may be required. With these 
specifications, DOE will select appropriate contractors, subcontractors, 
and expert consultants, as necessary, to perform the engineering 
analysis and the impact analysis. Also, the Department will consider 
data, information and analyses received from interested parties for use 
in the analysis wherever feasible.
    (b) The engineering analysis begins with the list of design options 
developed in consultation with the interested parties as a result of the 
screening process. In consultation with the technology/industry expert 
peer review group, the Department will establish the likely cost and 
performance improvement of each design option. Ranges and uncertainties 
of cost and performance will be established, although efforts will be 
made to minimize uncertainties by using measures such as test data or 
component or material supplier information where available. Estimated 
uncertainties will be carried forward in subsequent analyses. The use of 
quantitative models will be supplemented by qualitative assessments as 
appropriate.
    (c) The next step includes identifying, modifying or developing any 
engineering models necessary to predict the efficiency impact of any one 
or combination of design options on the product. A base case 
configuration or starting point will be established as well as the order 
and combination/blending of the design options to be evaluated. The DOE, 
utilizing expert consultants, will then perform the engineering analysis 
and develop the cost efficiency curve for the product. The cost 
efficiency curve and any necessary models will be subject to peer review 
before being issued with the ANOPR.

       10. Principles for the Analysis of Impacts on Manufacturers

    (a) Purpose. The purpose of the manufacturer analysis is to identify 
the likely impacts of efficiency standards on manufacturers. The 
Department will analyze the impact of standards on manufacturers with 
substantial input from manufacturers and other interested parties. The 
use of quantitative models will be supplemented by qualitative 
assessments by industry experts. This section describes the principles 
that will be used in conducting future manufacturing impact analysis.
    (b) Issue identification. In the impact analysis stage (section 
4(d)), the Department, in consultation with interested parties, will 
identify issues that will require greater consideration in the detailed 
manufacturer impact analysis. Possible issues may include identification 
of specific types or groups of manufacturers and concerns over access to 
technology. Specialized contractor expertise, empirical data 
requirements, and analytical tools required to perform the manufacturer 
impact analysis also would be identified at this stage.

[[Page 776]]

    (c) Industry characterization. Prior to initiating detailed impact 
studies, the Department will seek input on the present and past industry 
structure and market characteristics. Input on the following issues will 
be sought:
    (1) Manufacturers and their relative market shares;
    (2) Manufacturer characteristics, such as whether manufacturers make 
a full line of models or serve a niche market;
    (3) Trends in the number of manufacturers;
    (4) Financial situation of manufacturers;
    (5) Trends in product characteristics and retail markets; and
    (6) Identification of other relevant regulatory actions and a 
description of the nature and timing of any likely impacts.
    (d) Cost impacts on manufacturers. The costs of labor, material, 
engineering, tooling, and capital are difficult to estimate, 
manufacturer-specific, and usually proprietary. The Department will seek 
input from interested parties on the treatment of cost issues. 
Manufacturers will be encouraged to offer suggestions as to possible 
sources of data and appropriate data collection methodologies. Costing 
issues to be addressed include:
    (1) Estimates of total cost impacts, including product-specific 
costs (based on cost impacts estimated for the engineering analysis) and 
front-end investment/conversion costs for the full range of product 
models.
    (2) Range of uncertainties in estimates of average cost, considering 
alternative designs and technologies which may vary cost impacts and 
changes in costs of material, labor and other inputs which may vary 
costs.
    (3) Variable cost impacts on particular types of manufacturers, 
considering factors such as atypical sunk costs or characteristics of 
specific models which may increase or decrease costs.
    (e) Impacts on product sales, features, prices and cost recovery. In 
order to make manufacturer cash flow calculations, it is necessary to 
predict the number of products sold and their sale price. This requires 
an assessment of the likely impacts of price changes on the number of 
products sold and on typical features of models sold. Past analyses have 
relied on price and shipment data generated by economic models. The 
Department will develop additional estimates of prices and shipments by 
drawing on multiple sources of data and experience including: actual 
shipment and pricing experience, data from manufacturers, retailers and 
other market experts, financial models, and sensitivity analyses. The 
possible impacts of candidate standard levels on consumer choices among 
competing fuels will be explicitly considered where relevant.
    (f) Measures of impact. The manufacturer impact analysis will 
estimate the impacts of candidate standard levels on the net cash flow 
of manufacturers. Computations will be performed for the industry as a 
whole and for typical and atypical manufacturers. The exact nature and 
the process by which the analysis will be conducted will be determined 
by DOE, in conjunction with interested parties. Impacts to be analyzed 
include:
    (1) Industry net present value, with sensitivity analyses based on 
uncertainty of costs, sales prices and sales volumes;
    (2) Cash flows, by year;
    (3) Other measures of impact, such as revenue, net income and return 
on equity, as appropriate;
    The characteristics of atypical manufacturers worthy of special 
consideration will be determined in consultation with manufacturers and 
other interested parties and may include: manufacturers incurring higher 
or lower than average costs; and manufacturers experiencing greater or 
fewer adverse impacts on sales. Alternative scenarios based on other 
methods of estimating cost or sales impacts also will be performed, as 
needed.
    (g) Cumulative impacts of other Federal regulatory actions. (1) The 
Department will recognize and seek to mitigate the overlapping effects 
on manufacturers of new or revised DOE standards and other regulatory 
actions affecting the same products. DOE will analyze and consider the 
impact on manufacturers of multiple product-specific regulatory actions. 
These factors will be considered in setting rulemaking priorities, 
assessing manufacturer impacts of a particular standard, and 
establishing the effective date for a new or revised standard. In 
particular, DOE will seek to propose effective dates for new or revised 
standards that are appropriately coordinated with other regulatory 
actions to mitigate any cumulative burden.
    (2) If the Department determines that a proposed standard would 
impose a significant impact on product manufacturers within three years 
of the effective date of another DOE standard that imposes significant 
impacts on the same manufacturers (or divisions thereof, as 
appropriate), the Department will, in addition to evaluating the impact 
on manufacturers of the proposed standard, assess the joint impacts of 
both standards on manufacturers.
    (3) If the Department is directed to establish or revise standards 
for products that are components of other products subject to standards, 
the Department will consider the interaction between such standards in 
setting rulemaking priorities and assessing manufacturer impacts of a 
particular standard. The Department will assess, as part of the 
engineering and impact analyses, the cost of components subject to 
efficiency standards.
    (h) Summary of quantitative and qualitative assessments. The summary 
of quantitative and qualitative assessments will contain a description 
and discussion of uncertainties.

[[Page 777]]

Alternative estimates of impacts, resulting from the different potential 
scenarios developed throughout the analysis, will be explicitly 
presented in the final analysis results.
    (i) Key modeling and analytical tools. In its assessment of the 
likely impacts of standards on manufacturers, the Department will use 
models which are clear and understandable, feature accessible 
calculations, and have assumptions that are clearly explained. As a 
starting point, the Department will use the Government Regulatory Impact 
Model (GRIM). The Department will consider any enhancements to the GRIM 
that are suggested by interested parties. If changes are made to the 
GRIM methodology, DOE will provide notice and seek public input. The 
Department will also support the development of economic models for 
price and volume forecasting. Research required to update key economic 
data will be considered.

         11. Principles for the Analysis of Impacts on Consumers

    (a) Early consideration of impacts on consumer utility. The 
Department will consider at the earliest stages of the development of a 
standard whether particular design options will lessen the utility of 
the covered products to the consumer. See section 4(a).
    (b) Impacts on product availability. The Department will determine, 
based on consideration of information submitted during the standard 
development process, whether a proposed standard is likely to result in 
the unavailability of any covered product type with performance 
characteristics (including reliability), features, sizes, capacities, 
and volumes that are substantially the same as products generally 
available in the U.S. at the time. DOE will not promulgate a standard if 
it concludes that it would result in such unavailability.
    (c) Department of justice review. As required by law, the Department 
will solicit the views of the Justice Department on any lessening of 
competition that is likely to result from the imposition of a proposed 
standard and will give the views provided full consideration in 
assessing economic justification of a proposed standard. In addition, 
DOE may consult with the Department of Justice at earlier stages in the 
standards development process to seek to obtain preliminary views on 
competitive impacts.
    (d) Variation in consumer impacts. The Department will use regional 
analysis and sensitivity analysis tools, as appropriate, to evaluate the 
potential distribution of impacts of candidate standards levels among 
different subgroups of consumers. The Department will consider impacts 
on significant segments of consumers in determining standards levels. 
Where there are significant negative impacts on identifiable subgroups, 
DOE will consider the efficacy of voluntary approaches as a means to 
achieve potential energy savings.
    (e) Payback period and first cost. (1) In the assessment of consumer 
impacts of standards, the Department will consider Life-Cycle Cost, 
Payback Period and Cost of Conserved Energy to evaluate the savings in 
operating expenses relative to increases in purchase price. The 
Department intends to increase the level of sensitivity analysis and 
scenario analysis for future rulemakings. The results of these analyses 
will be carried throughout the analysis and the ensuing uncertainty 
described.
    (2) If, in the analysis of consumer impacts, the Department 
determines that a candidate standard level would result in a substantial 
increase in the product first costs to consumers or would not pay back 
such additional first costs through energy cost savings in less than 
three years, Department will specifically assess the likely impacts of 
such a standard on low-income households, product sales and fuel 
switching.

             12. Consideration of Non-Regulatory Approaches

    (a) The Department recognizes that voluntary or other non-regulatory 
efforts by manufacturers, utilities and other interested parties can 
result in substantial efficiency improvements. The Department intends to 
consider fully the likely effects of non-regulatory initiatives on 
product energy use, consumer utility and life cycle costs, 
manufacturers, competition, utilities and the environment, as well as 
the distribution of these impacts among different regions, consumers, 
manufacturers and utilities. DOE will attempt to base its assessment on 
the actual impacts of such initiatives to date, but also will consider 
information presented regarding the impacts that any existing initiative 
might have in the future. Such information is likely to include a 
demonstration of the strong commitment of manufacturers, distribution 
channels, utilities or others to such voluntary efficiency improvements. 
This information will be used in assessing the likely incremental 
impacts of establishing or revising standards, in assessing appropriate 
effective dates for new or revised standards and in considering DOE 
support of non-regulatory initiatives.
    (b) DOE believes that non-regulatory approaches are valuable 
complements to the standards program. In particular, DOE will consider 
pursuing voluntary programs where it appears that highly efficient 
products can obtain a significant market share but less efficient 
products cannot be eliminated altogether because, for instance, of 
unacceptable adverse impacts on a significant subgroup of consumers. In 
making this assessment, the Department will consider the success more 
efficient designs have had in the market,

[[Page 778]]

their acceptance to date, and their potential market penetration.

                 13. Crosscutting Analytical Assumptions

    In selecting values for certain crosscutting analytical assumptions, 
DOE expects to continue relying upon the following sources and general 
principles:
    (a) Underlying economic assumptions. The appliance standards 
analyses will generally use the same economic growth and development 
assumptions that underlie the most current Annual Energy Outlook (AEO) 
published by the Energy Information Administration (EIA).
    (b) Energy price and demand trends. Analyses of the likely impact of 
appliance standards on typical users will generally adopt the mid-range 
energy price and demand scenario of the EIA's most current AEO. The 
sensitivity of such estimated impacts to possible variations in future 
energy prices are likely to be examined using the EIA's high and low 
energy price scenarios.
    (c) Product-specific energy-efficiency trends, without updated 
standards. Product specific energy-efficiency trends will be based on a 
combination of the efficiency trends forecast by the EIA's residential 
and commercial demand model of the National Energy Modeling System 
(NEMS) and product-specific assessments by DOE and its contractors with 
input from interested parties.
    (d) Discount rates. For residential and commercial consumers, ranges 
of three different real discount rates will be used. For residential 
consumers, the mid-range discount rate will represent DOE's 
approximation of the average financing cost (or opportunity costs of 
reduced savings) experienced by typical consumers. Sensitivity analyses 
will be performed using discount rates reflecting the costs more likely 
to be experienced by residential consumers with little or no savings and 
credit card financing and consumers with substantial savings. For 
commercial users, a mid-range discount rate reflecting the DOE's 
approximation of the average real rate of return on commercial 
investment will be used, with sensitivity analyses being performed using 
values indicative of the range of real rates of return likely to be 
experienced by typical commercial businesses. For national net present 
value calculations, DOE would use the Administration's approximation of 
the average real rate of return on private investment in the U.S. 
economy. For manufacturer impacts, DOE plans to use a range of real 
discount rates which are representative of the real rates of return 
experienced by typical U.S. manufacturers affected by the program.
    (e) Environmental impacts. The emission rates of carbon, sulfur 
oxides and nitrogen oxides used by DOE to calculate the physical 
quantities of emissions likely to be avoided by candidate standard 
levels will be based on the current average carbon emissions of the U.S. 
electric utilities and on the projected rates of emissions of sulfur and 
nitrogen oxides. Projected rates of emissions, if available, will be 
used for the estimation of any other environmental impacts. The 
Department will consider the effects of the proposed standards on these 
emissions in reaching a decision about whether the benefits of the 
proposed standards exceed their burdens but will not determine the 
monetary value of these environmental externalities.

             14. Deviations, Revisions, and Judicial Review

    (a) Deviations. This appendix specifies procedures, interpretations 
and policies for the development of new or revised energy efficiency 
standards in considerable detail. As the approach described in this 
appendix is applied to the development of particular standards, the 
Department may find it necessary or appropriate to deviate from these 
procedures, interpretations or policies. If the Department concludes 
that such deviations are necessary or appropriate in a particular 
situation, DOE will provide interested parties with notice of the 
deviation and an explanation.
    (b) Revisions. If the Department concludes that changes to the 
procedures, interpretations or policies in this appendix are necessary 
or appropriate, DOE will provide notice in the Federal Register of 
modifications to this appendix with an accompanying explanation. DOE 
expects to consult with interested parties prior to any such 
modification.
    (c) Judicial review. The procedures, interpretations, and policies 
stated in this appendix are not intended to establish any new cause of 
action or right to judicial review.

    Subpart D_Petitions To Exempt State Regulation From Preemption; 
           Petitions To Withdraw Exemption of State Regulation

    Source: 54 FR 6078, Feb. 7, 1989, unless otherwise noted.



Sec. 430.40  Purpose and scope.

    (a) This subpart prescribes the procedures to be followed in 
connection with petitions requesting a rule that a State regulation 
prescribing an energy conservation standard, water conservation standard 
(in the case of faucets, showerheads, water closets, and urinals), or 
other requirement respecting energy efficiency, energy use, or water

[[Page 779]]

use (in the case of faucets, showerheads, water closets, and urinals) of 
a type (or class) of covered product not be preempted.
    (b) This subpart also prescribes the procedures to be followed in 
connection with petitions to withdraw a rule exempting a State 
regulation prescribing an energy conservation standard, water 
conservation standard (in the case of faucets, showerheads, water 
closets, and urinals), or other requirement respecting energy 
efficiency, energy use, or water use (in the case of faucets, 
showerheads, water closets, and urinals) of a type (or class) of covered 
product.

[63 FR 13318, Mar. 18, 1998]



Sec. 430.41  Prescriptions of a rule.

    (a) Criteria for exemption from preemption. Upon petition by a State 
which has prescribed an energy conservation standard, water conservation 
standard (in the case of faucets, showerheads, water closets, and 
urinals), or other requirement for a type or class of covered equipment 
for which a Federal energy conservation standard or water conservation 
standard is applicable, the Secretary shall prescribe a rule that such 
standard not be preempted if he determines that the State has 
established by a preponderance of evidence that such requirement is 
needed to meet unusual and compelling State or local energy interests or 
water interests. For the purposes of this section, the term ``unusual 
and compelling State or local energy interests or water interests'' 
means interests which are substantially different in nature or magnitude 
than those prevailing in the U.S. generally, and are such that when 
evaluated within the context of the State's energy plan and forecast, or 
water plan and forecast the costs, benefits, burdens, and reliability of 
energy savings or water savings resulting from the State regulation make 
such regulation preferable or necessary when measured against the costs, 
benefits, burdens, and reliability of alternative approaches to energy 
savings or water savings or production, including reliance on reasonably 
predictable market-induced improvements in efficiency of all equipment 
subject to the State regulation. The Secretary may not prescribe such a 
rule if he finds that interested persons have established, by a 
preponderance of the evidence, that the State's regulation will 
significantly burden manufacturing, marketing, distribution, sale or 
servicing of the covered equipment on a national basis. In determining 
whether to make such a finding, the Secretary shall evaluate all 
relevant factors including: the extent to which the State regulation 
will increase manufacturing or distribution costs of manufacturers, 
distributors, and others; the extent to which the State regulation will 
disadvantage smaller manufacturers, distributors, or dealers or lessen 
competition in the sale of the covered product in the State; the extent 
to which the State regulation would cause a burden to manufacturers to 
redesign and produce the covered product type (or class), taking into 
consideration the extent to which the regulation would result in a 
reduction in the current models, or in the projected availability of 
models, that could be shipped on the effective date of the regulation to 
the State and within the U.S., or in the current or projected sales 
volume of the covered product type (or class) in the State and the U.S.; 
and the extent to which the State regulation is likely to contribute 
significantly to a proliferation of State appliance efficiency 
requirements and the cumulative impact such requirements would have. The 
Secretary may not prescribe such a rule if he finds that such a rule 
will result in the unavailability in the State of any covered product 
(or class) of performance characteristics (including reliability), 
features, sizes, capacities, and volumes that are substantially the same 
as those generally available in the State at the time of the Secretary's 
finding. The failure of some classes (or types) to meet this criterion 
shall not affect the Secretary's determination of whether to prescribe a 
rule for other classes (or types).
    (1) Requirements of petition for exemption from preemption. A 
petition from a State for a rule for exemption from preemption shall 
include the information listed in paragraphs (a)(1)(i)

[[Page 780]]

through (a)(1)(vi) of this section. A petition for a rule and 
correspondence relating to such petition shall be available for public 
review except for confidential or proprietary information submitted in 
accordance with the Department of Energy's Freedom of Information 
Regulations set forth in 10 CFR part 1004:
    (i) The name, address, and telephone number of the petitioner;
    (ii) A copy of the State standard for which a rule exempting such 
standard is sought;
    (iii) A copy of the State's energy plan or water plan and forecast;
    (iv) Specification of each type or class of covered product for 
which a rule exempting a standard is sought;

    (b) Criteria for exemption from preemption when energy emergency 
conditions or water emergency conditions (in the case of faucets, 
showerheads, water closets, and urinals) exist within State. Upon 
petition by a State which has prescribed an energy conservation standard 
or water conservation standard (in the case of faucets, showerheads, 
water closets, and urinals) or other requirement for a type or class of 
covered product for which a Federal energy conservation standard or 
water conservation standard is applicable, the Secretary may prescribe a 
rule, effective upon publication in the Federal Register, that such 
State regulation not be preempted if he determines that in addition to 
meeting the requirements of paragraph (a) of this section the State has 
established that: an energy emergency condition or water emergency 
condition exists within the State that imperils the health, safety, and 
welfare of its residents because of the inability of the State or 
utilities within the State to provide adequate quantities of gas, 
electric energy, or water to its residents at less than prohibitive 
costs; and cannot be substantially alleviated by the importation of 
energy or water or the use of interconnection agreements; and the State 
regulation is necessary to alleviate substantially such condition.
    (1) Requirements of petition for exemption from preemption when 
energy emergency conditions or water emergency conditions (in the case 
of faucets, showerheads, water closets, and urinals) exist within a 
State. A petition from a State for a rule for exemption from preemption 
when energy emergency conditions or water emergency conditions exist 
within a State shall include the information listed in paragraphs 
(a)(1)(i) through (a)(1)(vi) of this section. A petition shall also 
include the information prescribed in paragraphs (b)(1)(i) through 
(b)(1)(iv) of this section, and shall be available for public review 
except for confidential or proprietary information submitted in 
accordance with the Department of Energy's Freedom of Information 
Regulations set forth in 10 CFR part 1004:
    (i) A description of the energy emergency condition or water 
emergency condition (in the case of faucets, showerheads, water closets, 
and urinals) which exists within the State, including causes and 
impacts.
    (ii) A description of emergency response actions taken by the State 
and utilities within the State to alleviate the emergency condition;
    (iii) An analysis of why the emergency condition cannot be 
alleviated substantially by importation of energy or water or the use of 
interconnection agreements; and
    (iv) An analysis of how the State standard can alleviate 
substantially such emergency condition.
    (2) [Reserved]
    (c) Criteria for withdrawal of a rule exempting a State standard. 
Any person subject to a State standard which, by rule, has been exempted 
from Federal preemption and which prescribes an energy conservation 
standard or water conservation standard (in the case of faucets, 
showerheads, water closets, and urinals) or other requirement for a type 
or class of a covered product, when the Federal energy conservation 
standard or water conservation standard (in the case of faucets, 
showerheads, water closets, and urinals) for such product subsequently 
is amended, may petition the Secretary requesting that the exemption 
rule be

[[Page 781]]

withdrawn. The Secretary shall consider such petition in accordance with 
the requirements of paragraph (a) of this section, except that the 
burden shall be on the petitioner to demonstrate that the exemption rule 
received by the State should be withdrawn as a result of the amendment 
to the Federal standard. The Secretary shall withdraw such rule if he 
determines that the petitioner has shown the rule should be withdrawn.
    (1) Requirements of petition to withdraw a rule exempting a State 
standard. A petition for a rule to withdraw a rule exempting a State 
standard shall include the information prescribed in paragraphs 
(c)(1)(i) through (c)(1)(vii) of this section, and shall be available 
for public review, except for confidential or proprietary information 
submitted in accordance with the Department of Energy's Freedom of 
Information Regulations set forth in 10 CFR part 1004:
    (i) The name, address and telephone number of the petitioner;
    (ii) A statement of the interest of the petitioner for which a rule 
withdrawing an exemption is sought;
    (iii) A copy of the State standard for which a rule withdrawing an 
exemption is sought;
    (iv) Specification of each type or class of covered product for 
which a rule withdrawing an exemption is sought;
    (v) A discussion of the factors contained in paragraph (a) of this 
section;
    (vi) Such other information, if any, believed to be pertinent by the 
petitioner; and
    (vii) Such other information as the Secretary may require.

Sec. 431.16  Test procedures for the measurement of energy efficiency.

    For purposes of 10 CFR part 431 and EPCA, the test procedures for 
measuring the energy efficiency of an electric motor shall be the test 
procedures specified in appendix B to this subpart B.



Sec. 431.17  Determination of efficiency.

    When a party determines the energy efficiency of an electric motor 
in order to comply with an obligation imposed on it by or pursuant to 
Part C of Title III of EPCA, 42 U.S.C. 6311-6316, this Section applies. 
This section does not apply to enforcement testing conducted pursuant to 
Sec. 431.192.
    (a) Provisions applicable to all electric motors--(1) General 
requirements. The average full load efficiency of each basic model of 
electric motor must be determined either by testing in accordance with 
Sec. 431.16 of this subpart, or by application of an alternative 
efficiency determination method (AEDM) that meets the requirements of 
paragraphs (a)(2) and (3) of this section, provided, however, that an 
AEDM may be used to determine the average full load efficiency of one or 
more of a manufacturer's basic models only if the average full load 
efficiency of at least five of its other basic models is determined 
through testing.
    (2) Alternative efficiency determination method. An AEDM applied to 
a basic model must be:
    (i) Derived from a mathematical model that represents the mechanical 
and electrical characteristics of that basic model, and
    (ii) Based on engineering or statistical analysis, computer 
simulation or

[[Page 797]]

modeling, or other analytic evaluation of performance data.
    (3) Substantiation of an alternative efficiency determination 
method. Before an AEDM is used, its accuracy and reliability must be 
substantiated as follows:
    (i) The AEDM must be applied to at least five basic models that have 
been tested in accordance with Sec. 431.16, and
    (ii) The predicted total power loss for each such basic model, 
calculated by applying the AEDM, must be within plus or minus ten 
percent of the mean total power loss determined from the testing of that 
basic model.
    (4) Subsequent verification of an AEDM. (i) Each manufacturer shall 
periodically select basic models representative of those to which it has 
applied an AEDM, and for each basic model selected shall either:
    (A) Subject a sample of units to testing in accordance with 
Sec. Sec. 431.16 and 431.17(b)(2) by an accredited laboratory that 
meets the requirements of Sec. 431.18;
    (B) Have a certification body recognized under Sec. 431.20 certify 
its nominal full load efficiency; or
    (C) Have an independent state-registered professional engineer, who 
is qualified to perform an evaluation of electric motor efficiency in a 
highly competent manner and who is not an employee of the manufacturer, 
review the manufacturer's representations and certify that the results 
of the AEDM accurately represent the total power loss and nominal full 
load efficiency of the basic model.
    (ii) Each manufacturer that has used an AEDM under this section 
shall have available for inspection by the Department of Energy records 
showing: the method or methods used; the mathematical model, the 
engineering or statistical analysis, computer simulation or modeling, 
and other analytic evaluation of performance data on which the AEDM is 
based; complete test data, product information, and related information 
that the manufacturer has generated or acquired pursuant to paragraphs 
(a)(3) and (a)(4)(i) of this section; and the calculations used to 
determine the average full load efficiency and total power losses of 
each basic model to which the AEDM was applied.
    (iii) If requested by the Department, the manufacturer shall conduct 
simulations to predict the performance of particular basic models of 
electric motors specified by the Department, analyses of previous 
simulations conducted by the manufacturer, sample testing of basic 
models selected by the Department, or a combination of the foregoing.
    (5) Use of a certification program or accredited laboratory. (i) A 
manufacturer may have a certification program, that DOE has classified 
as nationally recognized under Sec. 431.20, certify the nominal full 
load efficiency of a basic model of electric motor, and issue a 
certificate of conformity for the motor.
    (ii) For each basic model for which a certification program is not 
used as described in paragraph (a)(5)(i) of this section, any testing of 
the motor pursuant to paragraphs (a)(1) through (3) of this section to 
determine its energy efficiency must be carried out in accordance with 
paragraph (b) of this section, in an accredited laboratory that meets 
the requirements of Sec. 431.18. (This includes testing of the basic 
model, pursuant to paragraph (a)(3)(i) of this section, to substantiate 
an AEDM.)
    (b) Additional testing requirements applicable when a certification 
program is not used--(1) Selection of basic models for testing. (i) 
Basic models must be selected for testing in accordance with the 
following criteria:
    (A) Two of the basic models must be among the five basic models with 
the highest unit volumes of production by the manufacturer in the prior 
year, or during the prior 12 calendar month period beginning in 1997, 
\1\ whichever is later;
---------------------------------------------------------------------------

    \1\ In identifying these five basic models, any electric motor that 
does not comply with Sec. 431.25 shall be excluded from consideration.
---------------------------------------------------------------------------

    (B) The basic models should be of different horsepowers without 
duplication;
    (C) The basic models should be of different frame number series 
without duplication; and
    (D) Each basic model should be expected to have the lowest nominal 
full load efficiency among the basic models with the same rating 
(``rating'' as used

[[Page 798]]

here has the same meaning as it has in the definition of ``basic 
model'').
    (ii) In any instance where it is impossible for a manufacturer to 
select basic models for testing in accordance with all of these 
criteria, the criteria shall be given priority in the order in which 
they are listed. Within the limits imposed by the criteria, basic models 
shall be selected randomly.
    (2) Selection of units for testing. For each basic model selected 
for testing, \2\ a sample of units shall be selected at random and 
tested. The sample shall be comprised of production units of the basic 
model, or units that are representative of such production units. The 
sample size shall be not fewer than five units, except that when fewer 
than five units of a basic model would be produced over a reasonable 
period of time (approximately 180 days), then each unit shall be tested. 
In a test of compliance with a represented average or nominal 
efficiency:
---------------------------------------------------------------------------

    \2\ Components of similar design may be substituted without 
requiring additional testing if the represented measures of energy 
consumption continue to satisfy the applicable sampling provision.
---------------------------------------------------------------------------

    (i) The average full-load efficiency of the sample X which is 
defined by
[GRAPHIC] [TIFF OMITTED] TR83AD04.001


where Xi is the measured full-load efficiency of unit i and n is the 
number of units tested, shall satisfy the condition:
[GRAPHIC] [TIFF OMITTED] TR83AD04.002


where RE is the represented nominal full-load efficiency, and
    (ii) The lowest full-load efficiency in the sample Xmin, 
which is defined by
[GRAPHIC] [TIFF OMITTED] TR83AD04.003


shall satisfy the condition
[GRAPHIC] [TIFF OMITTED] TR83AD04.004

    (3) Substantiation of an alternative efficiency determination 
method. The basic models tested under Sec. 431.17(a)(3)(i) must be 
selected for testing in accordance with paragraph (b)(1) of this 
section, and units of each such basic model must be tested in accordance 
with paragraph (b)(2) of this section by an accredited laboratory that 
meets the requirements of Sec. 431.18.



Sec. 431.18  Testing laboratories.

    (a) Testing pursuant to Sec. 431.17(a)(5)(ii) must be conducted in 
an accredited laboratory for which the accreditation body was:
    (1) The National Institute of Standards and Technology/National 
Voluntary Laboratory Accreditation Program (NIST/NVLAP); or
    (2) A laboratory accreditation body having a mutual recognition 
arrangement with NIST/NVLAP; or
    (3) An organization classified by the Department, pursuant to Sec. 
431.19, as an accreditation body.
    (b) NIST/NVLAP is under the auspices of the National Institute of 
Standards and Technology (NIST)/National Voluntary Laboratory 
Accreditation Program (NVLAP), which is part of the U.S. Department of 
Commerce. NIST/NVLAP accreditation is granted on the basis of 
conformance with criteria published in 15 CFR Part 285. The National 
Voluntary Laboratory Accreditation Program, ``Procedures and General 
Requirements,'' NIST Handbook 150-10, February 2007, and Lab Bulletin 
LB-42-2009, Efficiency of Electric Motors Program, (referenced for 
guidance only, see Sec. 431.14) present the technical requirements of 
NVLAP for the Efficiency of Electric Motors field of accreditation. This 
handbook supplements NIST Handbook 150, National Voluntary Laboratory 
Accreditation Program ``Procedures and General Requirements,'' which 
contains 15 CFR part 285 plus all general NIST/NVLAP procedures, 
criteria, and policies. Information regarding NIST/NVLAP and its

    (e) For purposes of determining the required minimum nominal full-
load efficiency of an electric motor that has a horsepower or kilowatt 
rating between two horsepower or two kilowatt ratings listed in any 
table of energy conservation standards in paragraphs (a) through (d) of 
this section, each such motor shall be deemed to have a listed 
horsepower or kilowatt rating, determined as follows:
    (1) A horsepower at or above the midpoint between the two 
consecutive horsepowers shall be rounded up to the higher of the two 
horsepowers;
    (2) A horsepower below the midpoint between the two consecutive 
horsepowers shall be rounded down to the lower of the two horsepowers; 
or
    (3) A kilowatt rating shall be directly converted from kilowatts to 
horsepower using the formula 1 kilowatt = (\1\/0.746) 
horsepower. The conversion should be calculated to three significant 
decimal places, and the resulting horsepower shall be rounded in 
accordance with paragraph (e)(1) or (e)(2) of this section, whichever 
applies.
    (f) The standards in Table 1 through Table 4 of this section do not 
apply to definite purpose electric motors, special purpose electric 
motors, or those motors exempted by the Secretary.
    (g) The standards in Table 5 through Table 7 of this section apply 
only to electric motors, including partial electric motors, that satisfy 
the following criteria:
    (1) Are single-speed, induction motors;
    (2) Are rated for continuous duty (MG 1) operation or for duty type 
S1 (IEC);
    (3) Contain a squirrel-cage (MG 1) or cage (IEC) rotor;
    (4) Operate on polyphase alternating current 60-hertz sinusoidal 
line power;
    (5) Are rated 600 volts or less;
    (6) Have a 2-, 4-, 6-, or 8-pole configuration,
    (7) Are built in a three-digit or four-digit NEMA frame size (or IEC 
metric

[[Page 805]]

equivalent), including those designs between two consecutive NEMA frame 
sizes (or IEC metric equivalent), or an enclosed 56 NEMA frame size (or 
IEC metric equivalent),
    (8) Produce at least one horsepower (0.746 kW) but not greater than 
500 horsepower (373 kW), and
    (9) Meet all of the performance requirements of one of the following 
motor types: A NEMA Design A, B, or C motor or an IEC Design N or H 
motor.
    (h) Starting on June 1, 2016, each NEMA Design A motor, NEMA Design 
B motor, and IEC Design N motor that is an electric motor meeting the 
criteria in paragraph (g) of this section and with a power rating from 1 
horsepower through 500 horsepower, but excluding fire pump electric 
motors, manufactured (alone or as a component of another piece of 
equipment) shall have a nominal full-load efficiency of not less than

    (k) For purposes of determining the required minimum nominal full-
load efficiency of an electric motor that has a horsepower or kilowatt 
rating between two horsepower or two kilowatt ratings listed in any 
table of energy conservation standards in paragraphs (h) through (l) of 
this section, each

[[Page 807]]

such motor shall be deemed to have a listed horsepower or kilowatt 
rating, determined as follows:
    (1) A horsepower at or above the midpoint between the two 
consecutive horsepowers shall be rounded up to the higher of the two 
horsepowers;
    (2) A horsepower below the midpoint between the two consecutive 
horsepowers shall be rounded down to the lower of the two horsepowers; 
or
    (3) A kilowatt rating shall be directly converted from kilowatts to 
horsepower using the formula 1 kilowatt = (\1\/ 0.746) 
horsepower. The conversion should be calculated to three significant 
decimal places, and the resulting horsepower shall be rounded in 
accordance with paragraph (k)(1) or (k)(2) of this section, whichever 
applies.
    (l) The standards in Table 5 through Table 7 of this section do not 
apply to the following electric motors exempted by the Secretary, or any

[69 FR 61923, Oct. 21, 2004, as amended at 77 FR 26637, May 4, 2012]



Sec. 431.32  Preemption of State regulations.

    The provisions of Sec. 431.31 supersede any State regulation to the 
extent required by Section 327 of the Act. Pursuant to the Act, all 
State regulations that require the disclosure for any electric motor of 
information with respect to energy consumption, other than the 
information required to be disclosed in accordance with this part, are 
superseded.

                              Certification



Sec. 431.35  Applicability of certification requirements.

    Section 431.36 sets forth the procedures for manufacturers to 
certify that electric motors comply with the applicable energy 
efficiency standards set forth in this subpart.



Sec. 431.36  Compliance Certification.

    (a) General. A manufacturer or private labeler shall not distribute 
in commerce any basic model of an electric motor which is subject to an 
energy efficiency standard set forth in this subpart unless it has 
submitted to the Department a Compliance Certification certifying, in 
accordance with the provisions of this section, that the basic model 
meets the requirements of the applicable standard. The representations 
in the Compliance Certification must be based upon the basic model's 
energy efficiency as determined in accordance with the applicable 
requirements of this subpart. This means, in part, that either:
    (1) The representations as to the basic model must be based on use 
of a certification organization; or
    (2) Any testing of the basic model on which the representations are 
based must be conducted at an accredited laboratory.
    (b) Required contents--(1) General representations. Each Compliance 
Certification must certify that:
    (i) The nominal full load efficiency for each basic model of 
electric motor distributed is not less than the minimum nominal full 
load efficiency required for that motor by Sec. 431.25;
    (ii) All required determinations on which the Compliance 
Certification is based were made in compliance with the applicable 
requirements prescribed in this subpart;
    (iii) All information reported in the Compliance Certification is 
true, accurate, and complete; and
    (iv) The manufacturer or private labeler is aware of the penalties 
associated with violations of the Act and the regulations thereunder, 
and of 18 U.S.C. 1001 which prohibits knowingly making false statements 
to the Federal Government.
    (2) Specific data. (i) For each rating of electric motor (as the 
term ``rating'' is defined in the definition of basic model) which a 
manufacturer or private labeler distributes, the Compliance 
Certification must report the nominal full load efficiency, determined 
pursuant to Sec. Sec. 431.16 and 431.17, of the least efficient basic 
model within that rating.
    (ii) The Compliance Certification must identify the basic models on 
which actual testing has been performed to meet the requirements of 
Sec. 431.17.
    (iii) The format for a Compliance Certification is set forth in 
appendix C of this subpart.
    (c) Optional contents. In any Compliance Certification, a 
manufacturer or private labeler may at its option request that DOE 
provide it with a unique Compliance Certification number (``CC number'') 
for any brand name, trademark or other label name under which the 
manufacturer or private labeler distributes electric motors covered by 
the Certification. Such a Compliance Certification must also identify 
all other names, if any, under which the manufacturer or private labeler 
distributes electric motors, and to which the request does not apply.
    (d) Signature and submission. A manufacturer or private labeler must 
submit the Compliance Certification either on

[[Page 809]]

its own behalf, signed by a corporate official of the company, or 
through a third party (for example, a trade association or other 
authorized representative) acting on its behalf. Where a third party is 
used, the Compliance Certification must identify the official of the 
manufacturer or private labeler who authorized the third party to make 
representations on the company's behalf, and must be signed by a 
corporate official of the third party. The Compliance Certification must 
be submitted to the Department electronically at https://
www.regulations.doe.gov /ccms. Alternatively, the Compliance 
Certification may be submitted by certified mail to: Certification and 
Compliance Reports, U.S. Department of Energy, Office of Energy 
Efficiency and Renewable Energy, Building Technologies Program, EE-2J, 
Forrestal Building, 1000 Independence Avenue, SW., Washington, DC 20585-
0121.
    (e) New basic models. For electric motors, a Compliance 
Certification must be submitted for a new basic model only if the 
manufacturer or private labeler has not previously submitted to DOE a 
Compliance Certification, that meets the requirements of this section, 
for a basic model that has the same rating as the new basic model, and 
that has a lower nominal full load efficiency than the new basic model.
    (f) Response to Compliance Certification; Compliance Certification 
Number (CC number)--(1) DOE processing of Certification. Promptly upon 
receipt of a Compliance Certification, the Department will determine 
whether the document contains all of the elements required by this 
section, and may, in its discretion, determine whether all or part of 
the information provided in the document is accurate. The Department 
will then advise the submitting party in writing either that the 
Compliance Certification does not satisfy the requirements of this 
section, in which case the document will be returned, or that the 
Compliance Certification satisfies this section. The Department will 
also advise the submitting party of the basis for its determination.
    (2) Issuance of CC number(s). (i) Initial Compliance Certification. 
When DOE advises that the initial Compliance Certification submitted by 
or on behalf of a manufacturer or private labeler is acceptable, either:
    (A) DOE will provide a single unique CC number, ``CC____,'' to the 
manufacturer or private labeler, and such CC number shall be applicable 
to all electric motors distributed by the manufacturer or private 
labeler, or
    (B) When required by paragraph (f)(3) of this section, DOE will 
provide more than one CC number to the manufacturer or private labeler.
    (ii) Subsequent Compliance Certification. When DOE advises that any 
other Compliance Certification is acceptable, it will provide a unique 
CC number for any brand name, trademark or other name when required by 
paragraph (f)(3) of this section.
    (iii) When DOE declines to provide a CC number as requested by a 
manufacturer or private labeler in accordance with Sec. 431.36(c), DOE 
will advise the requester of the reasons for such refusal.
    (3) Issuance of two or more CC numbers. (i) DOE will provide a 
unique CC number for each brand name, trademark or other label name for 
which a manufacturer or private labeler requests such a number in 
accordance with Sec. 431.36(c), except as follows. DOE will not provide 
a CC number for any brand name, trademark or other label name
    (A) For which DOE has previously provided a CC number, or
    (B) That duplicates or overlaps with other names under which the 
manufacturer or private labeler sells electric motors.
    (ii) Once DOE has provided a CC number for a particular name, that 
shall be the only CC number applicable to all electric motors

           Sec. Appendix A to Subpart B of Part 431 [Reserved]



   Sec. Appendix B to Subpart B of Part 431--Uniform Test Method for 
        Measuring Nominal Full Load Efficiency of Electric Motors

    Note: After June 11, 2014, any representations made with respect to 
the energy use or efficiency of electric motors for which energy 
conservation standards are currently provided at 10 CFR 431.25 must be 
made in accordance with the results of testing pursuant to this 
appendix.
    For manufacturers conducting tests of motors for which energy 
conservation standards are provided at 10 CFR 431.25, after January 13, 
2014 and prior to June 11, 2014, manufacturers must conduct such test in 
accordance with either this appendix or appendix B as it appeared at 10 
CFR Part 431, subpart B, appendix B, in the 10 CFR Parts 200 to 499 
edition revised as of January 1, 2013. Any representations made with 
respect to the energy use or efficiency of such electric motors must be 
in accordance with whichever version is selected. Given that after June 
11, 2014 representations with respect to the energy use or efficiency of 
electric motors must be made in accordance with tests conducted pursuant 
to this appendix, manufacturers may wish to begin using this test 
procedure as soon as possible.
    For any other electric motor type that is not currently covered by 
the energy conservation standards at 10 CFR 431.25, manufacturers of 
this equipment will need to use Appendix B 180 days after the effective 
date of the final rule adopting energy conservation standards for these 
motors.

    1. Definitions.
    Definitions contained in Sec. Sec. 431.2 and 431.12 are applicable 
to this appendix.
    2. Test Procedures.
    Efficiency and losses shall be determined in accordance with NEMA 
MG1-2009, paragraph 12.58.1, ``Determination of Motor Efficiency and 
Losses,'' (incorporated by reference, see Sec. 431.15) and either:
    (1) CSA C390-10, (incorporated by reference, see Sec. 431.15), or
    (2) IEEE Std 112-2004 Test Method B, Input-Output With Loss 
Segregation, (incorporated by reference, see Sec. 431.15).
    3. Amendments to test procedures.
    Any revision to IEEE Std 112-2004 Test Method B, NEMA MG1-2009, or 
CSA C390-10, (incorporated by reference, see Sec. 431.15) shall not be 
effective for purposes of certification and compliance testing unless 
and until this appendix and 10 CFR Part 431 are amended to incorporate 
that revision.
    4. Procedures for the Testing of Certain Electric Motor Types.
    Prior to testing according to IEEE Std 112-2004 (Test Method B) or 
CSA C390-10 (incorporated by reference, see Sec. 431.15), each basic 
model of the electric motor types listed below must be set up in 
accordance with the instructions of this section to ensure consistent 
test results. These steps are designed to enable a motor to be attached 
to a dynamometer and run continuously for testing purposes. For the 
purposes of this appendix, a ``standard bearing'' is a 6000 series, 
either open or grease-lubricated double-shielded, single-row, deep 
groove, radial ball bearing.
    4.1 Brake Electric Motors:
    Brake electric motors shall be tested with the brake component 
powered separately from the motor such that it does not activate during 
testing. Additionally, for any 10-minute period during the test and 
while the brake is being powered such that it remains disengaged from 
the motor shaft, record the power consumed (i.e., watts). Only power 
used to drive the motor is to be included in the efficiency calculation; 
power supplied to prevent the brake from engaging is not included in 
this calculation. In lieu of powering the brake separately, the brake 
may be disengaged mechanically, if such a mechanism exists and if the 
use of this mechanism does not yield a different efficiency value than 
separately powering the brake electrically.
    4.2 Close-Coupled Pump Electric Motors and Electric Motors with 
Single or Double Shaft Extensions of Non-Standard Dimensions or Design:
    To attach the unit under test to a dynamometer, close-coupled pump 
electric motors and electric motors with single or double shaft 
extensions of non-standard dimensions or design must be tested using a 
special coupling adapter.
    4.3 Electric Motors with Non-Standard Endshields or Flanges:
    If it is not possible to connect the electric motor to a dynamometer 
with the non-standard endshield or flange in place, the testing 
laboratory shall replace the non-standard endshield or flange with an 
endshield or flange meeting NEMA or IEC specifications. The replacement 
component should be obtained from the manufacturer or, if the 
manufacturer chooses, machined by the testing laboratory after 
consulting with the manufacturer regarding the critical characteristics 
of the endshield.
    4.4 Electric Motors with Non-Standard Bases, Feet or Mounting 
Configurations
    An electric motor with a non-standard base, feet, or mounting 
configuration may be mounted on the test equipment using adaptive 
fixtures for testing as long as the mounting or use of adaptive mounting 
fixtures does not have an adverse impact on the performance of the 
electric motor, particularly on the cooling of the motor.
    4.5 Electric Motors with a Separately-powered Blower:

[[Page 811]]

    For electric motors furnished with a separately-powered blower, the 
losses from the blower's motor should not be included in any efficiency 
calculation. This can be done either by powering the blower's motor by a 
source separate from the source powering the electric motor under test 
or by connecting leads such that they only measure the power of the 
motor under test.
    4.6 Immersible Electric Motors
    Immersible electric motors shall be tested with all contact seals 
removed but be otherwise unmodified.
    4.7 Partial Electric Motors:
    Partial electric motors shall be disconnected from their mated piece 
of equipment. After disconnection from the equipment, standard bearings 
and/or endshields shall be added to the motor, such that it is capable 
of operation. If an endshield is necessary, an endshield meeting NEMA or 
IEC specifications should be obtained from the manufacturer or, if the 
manufacturer chooses, machined by the testing laboratory after 
consulting with the manufacturer regarding the critical characteristics 
of the endshield.
    4.8 Vertical Electric Motors and Electric Motors with Bearings 
Incapable of Horizontal Operation:
    Vertical electric motors and electric motors with thrust bearings 
shall be tested in a horizontal or vertical configuration in accordance 
with IEEE 112 (Test Method B), depending on the testing facility's 
capabilities and construction of the motor, except if the motor is a 
vertical solid shaft normal thrust general purpose electric motor 
(subtype II), in which case it shall be tested in a horizontal 
configuration in accordance with IEEE 112 (Test Method B). Preference 
shall be given to testing a motor in its native orientation. If the unit 
under test cannot be reoriented horizontally due to its bearing 
construction, the electric motor's bearing(s) shall be removed and 
replaced with standard bearings. If the unit under test contains oil-
lubricated bearings, its bearings shall be removed and replaced with 
standard bearings. Finally, if the unit under test contains a hollow 
shaft, a solid shaft shall be inserted, bolted to the non-drive end of 
the motor and welded on the drive end. Enough clearance shall be 
maintained such that attachment to a dynamometer is possible.

    (2) For commercial refrigeration equipment with two or more 
compartments (i.e., hybrid refrigerators, hybrid freezers, hybrid 
refrigerator-freezers, and non-hybrid refrigerator-freezers), the 
maximum daily energy consumption for each model shall be the sum of the 
MDEC values for all of its compartments. For each compartment, measure 
the TDA or volume of that compartment, and determine the appropriate 
equipment class based on that compartment's equipment family, condensing 
unit configuration, and designed operating temperature. The MDEC limit 
for each compartment shall be the calculated value obtained by entering 
that compartment's TDA or volume into the standard equation in paragraph 
(e)(1) of this section for that compartment's equipment class. Measure 
the CDEC or TDEC for the entire case as described in Sec. 
431.66(d)(2)(i) through (iii), except that where measurements and 
calculations reference ARI Standard 1200-2006 (incorporated by 
reference, see Sec. 431.63), AHRI Standard 1200 (I-P)-2010 
(incorporated by reference, see Sec. 431.63) shall be used.
    (3) For remote condensing and self-contained wedge cases, measure 
the CDEC or TDEC according to the AHRI Standard 1200 (I-P)-2010 test 
procedure (incorporated by reference, see Sec. 431.63). For wedge cases 
in equipment classes for which a volume metric is used, the MDEC shall 
be the amount derived from the appropriate standards equation in 
paragraph (e)(1) of this section. For wedge cases of equipment classes 
for which a TDA metric is used, the MDEC for each model shall be the 
amount derived by incorporating into the standards equation in paragraph 
(e)(1) of this section for the equipment class a value for the TDA that 
is the product of:
    (i) The vertical height of the air curtain (or glass in a 
transparent door) and
    (ii) The largest overall width of the case, when viewed from the 
front.
    (f) Exclusions. The energy conservation standards in paragraphs (b) 
through (e) of this section do not apply to salad bars, buffet tables, 
and chef bases or griddle stands.

 Sec. Appendix A to Subpart C of Part 431--Uniform Test Method for the 
Measurement of Energy Consumption of Commercial Refrigerators, 
Freezers,and Refrigerator-Freezers

    Note: After October 20, 2014 but before March 28, 2017, any 
representations made with respect to the energy use or efficiency of 
commercial refrigeration equipment must be made in accordance with the 
results of testing pursuant to this appendix.
    Manufacturers conducting tests of commercial refrigeration equipment 
after May 21, 2014 and prior to October 20, 2014, must conduct such test 
in accordance with either this appendix or Sec. 431.64 as it appeared 
at 10 CFR part 430, subpart B, in the 10 CFR parts 200 to 499 edition 
revised as of January 1, 2014. Any representations made with respect to 
the energy use or efficiency of such commercial refrigeration equipment 
must be in accordance with whichever version is selected. Given that 
after October 20, 2014 representations with respect to the energy use or 
efficiency of commercial refrigeration equipment must be made in 
accordance with tests conducted pursuant to this appendix, manufacturers 
may wish to begin using this test procedure as soon as possible.

                            1. Test Procedure

    1.1. Determination of Daily Energy Consumption. Determine the daily 
energy consumption of each covered commercial refrigerator, freezer, 
refrigerator-freezer or ice-cream freezer by conducting the test 
procedure set forth in the Air-Conditioning and Refrigeration Institute 
(ARI) Standard 1200-2006, ``Performance Rating of Commercial 
Refrigerated Display Merchandisers and Storage Cabinets,'' section 3, 
``Definitions,'' section 4, ``Test Requirements,'' and section 7, 
``Symbols and Subscripts'' (incorporated by reference, see Sec. 
431.63). For each commercial refrigerator, freezer, or refrigerator-
freezer with a self-contained condensing unit, also use ARI Standard 
1200-2006, section 6, ``Rating Requirements for Self-contained 
Commercial Refrigerated Display Merchandisers and Storage Cabinets.'' 
For each commercial refrigerator, freezer, or refrigerator-freezer with 
a remote condensing unit, also use ARI Standard 1200-2006, section 5, 
``Rating Requirements for Remote Commercial Refrigerated Display 
Merchandisers and Storage Cabinets.''

[[Page 823]]

    1.2. Methodology for Determining Applicability of Transparent Door 
Equipment Families. To determine if a door for a given model of 
commercial refrigeration equipment is transparent: (1) Calculate the 
outer door surface area including frames and mullions; (2) calculate the 
transparent surface area within the outer door surface area excluding 
frames and mullions; (3) calculate the ratio of (2) to (1) for each of 
the outer doors; and (4) the ratio for the transparent surface area of 
all outer doors must be greater than 0.25 to qualify as a transparent 
equipment family.
    1.3. Additional Specifications for Testing of Components and 
Accessories. Subject to the provisions regarding specific components and 
accessories listed below, all standard components that would be used 
during normal operation of the basic model in the field shall be 
installed and in operation during testing as recommended by the 
manufacturer and representative of their typical operation in the field 
unless such installation and operation is inconsistent with any 
requirement of the test procedure. The specific components and 
accessories listed in the subsequent sections shall be operated as 
stated during the test.
    1.3.1. Energy Management Systems. Applicable energy management 
systems may be activated during the test procedure provided they are 
permanently installed on the case, configured as sold and in such a 
manner so as to operate automatically without the intervention of the 
operator, and do not conflict with any of other requirements for a valid 
test as specified in this appendix.
    1.3.2. Lighting. Energize all lighting, except customer display 
signs/lights as described in section 1.3.3 and UV lighting as described 
in section 1.3.6 of this appendix, to the maximum illumination level for 
the duration of testing. However, if a closed solid unit of commercial 
refrigeration equipment includes an automatic lighting control system 
that can turn off internal case lighting when the door is closed, and 
the manufacturer recommends the use of this system in writing in the 
product literature delivered with the unit, then the lighting control 
should be operated in the automatic setting, even if the model has a 
manual switch that disables the automatic lighting control.
    1.3.3. Customer display signs/lights. Do not energize supplemental 
lighting that exists solely for the purposes of advertising or drawing 
attention to the case and is not integral to the operation of the case.
    1.3.4. Condensate pan heaters and pumps. For self-contained 
equipment only, all electric resistance condensate heaters and 
condensate pumps must be installed and operational during the test. This 
includes the stabilization period (including pull-down), steady-state, 
and performance testing periods. Prior to the start of the stabilization 
period as defined by ASHRAE 72-2005 (incorporated by reference, see 
Sec. 431.63), the condensate pan must be dry. Following the start of 
the stabilization period, allow any condensate moisture generated to 
accumulate in the pan. Do not manually add or remove water from the 
condensate pan at any time during the test.
    1.3.5. Anti-sweat door heaters. Anti-sweat door heaters must be in 
operation during the entirety of the test procedure. Models with a user-
selectable setting must have the heaters energized and set to the 
maximum usage position. Models featuring an automatic, non-user-
adjustable controller that turns on or off based on environmental 
conditions must be operating in the automatic state. If a unit is not 
shipped with a controller from the point of manufacture and is intended 
to be used with an automatic, non-user-adjustable controller, test the 
unit with a manufacturer-recommended controller that turns on or off 
based on environmental conditions.
    1.3.6. Ultraviolet lights. Do not energize ultraviolet lights during 
the test.
    1.3.7. Illuminated temperature displays and alarms. All illuminated 
temperature displays and alarms shall be energized and operated during 
the test as they would be during normal field operation.
    1.3.8. Condenser filters. Remove any nonpermanent filters that are 
provided to prevent particulates from blocking a model's condenser coil.
    1.3.9. Refrigeration system security covers. Remove any devices used 
to secure the condensing unit against unwanted removal.
    1.3.10. Night curtains and covers. Do not deploy night curtains or 
covers.
    1.3.11. Grill options. Remove any optional, non-standard grills used 
to direct airflow.
    1.3.12. Misting or humidification systems. Misting or humidification 
systems must be inactive during the test.
    1.3.13. Air purifiers. Air purifiers must be inactive during the 
test.
    1.3.14. General purpose outlets. During the test, do not connect any 
external load to any general purpose outlets contained within a unit.
    1.3.15. Crankcase heaters. Crankcase heaters must be operational 
during the test. If a control system, such as a thermostat or electronic 
controller, is used to modulate the operation of the crankcase heater, 
it must be activated during the test.
    1.3.16. Drawers. Drawers are to be treated as identical to doors 
when conducting the DOE test procedure. Commercial refrigeration 
equipment with drawers should be configured with the drawer pans that 
allow for the maximum packing of test simulators and filler packages 
without the filler packages and test simulators exceeding 90 percent of

[[Page 824]]

the refrigerated volume. Packing of test simulators and filler packages 
shall be in accordance with the requirements for commercial 
refrigerators without shelves, as specified in section 6.2.3 of ASHRAE 
72-2005 (incorporated by reference, see Sec. 431.63).

                           2. Test Conditions

    2.1. Integrated Average Temperatures. Conduct the testing required 
in section 1 and 2 of this appendix A, and determine the daily energy 
consumption at the applicable integrated average temperature as found in 
the following table.

    2.2. Lowest Application Product Temperature. If a unit of commercial 
refrigeration equipment is not able to be operated at the integrated 
average temperature specified in the table in paragraph 2.1, test the 
unit at the lowest application product temperature (LAPT), as defined in 
Sec. 431.62. For units equipped with a thermostat, LAPT is the lowest 
thermostat setting. For remote condensing equipment without a thermostat 
or other means of controlling temperature at the case, the lowest 
application product temperature is the temperature achieved with the dew 
point temperature (as defined in AHRI Standard 1200 (I-P)-2010 
(incorporated by reference see Sec. 431.63)) set to 5 degrees colder 
than that required to maintain the manufacturer's lowest specified 
operating temperature.
    2.3. Testing at NSF Test Conditions. For commercial refrigeration 
equipment that is also tested in accordance with NSF test procedures 
(Type I and Type II), integrated average temperatures and ambient 
conditions used for NSF testing may be used in place of the DOE-
prescribed integrated average temperatures and ambient conditions 
provided they result in a more stringent test. That is, the measured 
daily energy consumption of the same unit, when tested at the rating 
temperatures and/or ambient conditions specified in the DOE test 
procedure, must be lower than or equal to the measured daily energy 
consumption of the unit when tested with the rating temperatures or 
ambient conditions used for NSF testing. The integrated average 
temperature measured during the test may be lower than the range 
specified by the DOE applicable temperature specification provided in 
paragraph 2.1 of this appendix, but may not exceed the upper value of 
the specified range. Ambient temperatures and/or humidity values may be 
higher than those specified in the DOE test procedure.

                    3. Volume and Total Display Area

    3.1. Determination of Volume. Determine the volume of a commercial 
refrigerator, freezer, refrigerator-freezer, or ice-cream freezer using 
the method set forth in the ANSI/AHAM HRF-1-2004, ``Energy, Performance 
and Capacity of Household Refrigerators, Refrigerator-Freezers and 
Freezers'' (incorporated by reference, see Sec. 431.63), section 3.21, 
``Volume,'' sections 4.1 through 4.3, ``Method for Computing Total 
Refrigerated Volume and Total Shelf Area of Household Refrigerators and 
Household Wine Chillers,'' and sections 5.1 through 5.3, ``Method for 
Computing Total Refrigerated Volume and Total Shelf Area of Household 
Freezers.''
    3.2. Determination of Total Display Area. Determine the total 
display area of a commercial refrigerator, freezer, refrigerator-
freezer, or ice-cream freezer using the method set forth in ARI Standard 
1200-2006 (incorporated by reference, see Sec. 431.63), but 
disregarding the specification that ``transparent material 
(=65% light transmittance) in Appendix D. Specifically, total 
display

[[Page 825]]

area shall be the sum of the projected area(s) of visible product, 
expressed in ft \2\ (i.e., portions through which product can be viewed 
from an angle normal, or perpendicular, to the transparent area). 
Determine L as the interior length of the CRE model, provided no more 
than 10 percent of that length consists of non-transparent material. For 
those cases with greater than 10 percent of non-transparent area, L 
shall be determined as the projected linear dimension(s) of visible 
product plus 10 percent of non-transparent area.
    See Figures A3.1, A3.2, A3.3, A3.4, and A3.5 as examples of how to 
calculate the dimensions associated with calculation of total display 
area. In the diagrams, Dh and L represent the dimensions of 
the projected visible product.

 Sec. Appendix B to Subpart C of Part 431--Amended Uniform Test Method 
 for the Measurement of Energy Consumption of Commercial
 Refrigerators, Freezers, and Refrigerator-Freezers

    Note: Any representations made on or after March 28, 2017, with 
respect to the energy use or efficiency of commercial refrigeration 
equipment must be made in accordance with the results of testing 
pursuant to this appendix.

                            1. Test Procedure

    1.1. Determination of Daily Energy Consumption. Determine the daily 
energy consumption of each covered commercial refrigerator, freezer, 
refrigerator-freezer or ice-cream freezer by conducting the test 
procedure set forth in the AHRI Standard 1200 (I-P)-2010, section 3, 
``Definitions,'' section 4, ``Test Requirements,'' and section 7, 
``Symbols and Subscripts'' (incorporated by reference, see Sec. 
431.63). For each commercial refrigerator, freezer, or refrigerator-
freezer with a self-contained condensing unit, also use AHRI Standard 
1200 (I-P)-2010, section 6, ``Rating Requirements for Self-contained 
Commercial Refrigerated Display Merchandisers and Storage Cabinets.'' 
For each commercial refrigerator, freezer, or refrigerator-freezer with 
a remote condensing unit, also use AHRI Standard 1200 (I-P)-2010, 
section 5, ``Rating Requirements for Remote Commercial Refrigerated 
Display Merchandisers and Storage Cabinets.''

   1.2. Methodology for Determining Applicability of Transparent Door 
                           Equipment Families

    To determine if a door for a given model of commercial refrigeration 
equipment is transparent: (1) Calculate the outer door surface area 
including frames and mullions; (2) calculate the transparent surface 
area within the outer door surface area excluding frames and mullions; 
(3) calculate the ratio of (2) to (1) for each of the outer doors; and 
(4) the ratio for the transparent surface area of all outer doors must 
be greater than 0.25 to qualify as a transparent equipment family.
    1.3. Additional Specifications for Testing of Components and 
Accessories. All standard components that would be used during normal 
operation of the basic model in the field shall be installed and used 
during testing as

[[Page 829]]

recommended by the manufacturer and representative of their typical 
operation in the field unless such installation and operation is 
inconsistent with any requirement of the test procedure. The specific 
components and accessories listed in the subsequent sections shall be 
operated as stated during the test.
    1.3.1. Energy Management Systems. Applicable energy management 
systems may be activated during the test procedure provided they are 
permanently installed on the case, configured and sold in such a manner 
so as to operate automatically without the intervention of the operator, 
and do not conflict with any of other requirements for a valid test as 
specified in this appendix.
    1.3.2. Lighting. All lighting except for customer display signs/
lights as described in section 1.3.3 and UV lighting as described in 
section 1.3.6 of this appendix shall be energized to the maximum 
illumination level for the duration of testing for commercial 
refrigeration equipment with lighting except when the unit is equipped 
with lighting occupancy sensors and controls. If the unit includes an 
automatic lighting control system, it should be enabled during test. If 
the unit is equipped with lighting occupancy sensors and controls in 
should be tested in accordance with section 1.3.2.1 of this appendix.
    1.3.2.1. Lighting Occupancy Sensors and Controls. For units with 
lighting occupancy sensors and/or scheduled lighting controls installed 
on the unit, determine the effect of the controls/sensors on daily 
energy consumption by either a physical test or a calculation method and 
using the variables that are defined as:
    CECA is the alternate compressor energy consumption (kilowatt-
hours);
    LECsc is the lighting energy consumption of internal case lights 
with lighting occupancy sensors and controls deployed (kilowatt-hours);
    Pli is the rated power of lights when they are fully on (watts);
    Pli(off) is the power of lights when they are off (watts);
    Pli(dim) is the power of lights when they are dimmed (watts);
    TDECo is the total daily energy consumption with lights fully on, as 
measured by AHRI Standard 1200 (I-P)-2010 (kilowatt-hours);
    tdim is the time period during which the lights are dimmed due to 
the use of lighting occupancy sensors or scheduled lighting controls 
(hours);
    tdim,controls is the time case lighting is dimmed due to the use of 
lighting controls (hours);
    tdim,sensors is the time case lighting is dimmed due to the use of 
lighting occupancy sensors (hours);
    tl is the time period when lights would be on without lighting 
occupancy sensors and/or scheduled lighting controls (24 hours);
    toff is the time period during which the lights are off due to the 
use of lighting occupancy sensors and/or scheduled lighting controls 
(hours);
    toff,controls is the time case lighting is off due to the use of 
scheduled lighting controls (hours);
    toff,sensors is the time case lighting is off due to the use of 
lighting occupancy sensors (hours); and
    tsc is the time period when lighting is fully on with lighting 
occupancy sensors and scheduled lighting controls enabled (hours).
    1.3.2.1.i. For both a physical test and a calculation method, 
determine the estimated time off or dimmed, toff or 
tdim, as the sum of contributions from lighting occupancy 
sensors and scheduled lighting controls that dim or turn off lighting, 
respectively, as shown in the following equation:
[GRAPHIC] [TIFF OMITTED] TR21AP14.003

[GRAPHIC] [TIFF OMITTED] TR21AP14.004

    The sum of tsc, toff, and tdim 
should equal 24 hours and the total time period during which the lights 
are off or dimmed shall not exceed 10.8 hours. For cases with scheduled 
lighting controls, the time the case lighting is off and/or dimmed due 
to scheduled lighting controls (toff,controls and/or 
tdim,controls, as applicable) shall not exceed 8 hours. For 
cases with lighting occupancy sensors installed, the time the case 
lighting is off and/or dimmed due to lighting occupancy sensors 
(toff,sensors and/or tdim,sensors, as applicable) 
shall not exceed 10.8 hours. For cases with lighting occupancy sensors 
and scheduled lighting controls installed, the time the case lighting is 
off and/or dimmed due to lighting occupancy sensors 
(toff,sensors and/or tdim,sensors, as applicable) 
shall not exceed 2.8 hours and the time the case lighting is off and/or 
dimmed due to scheduled lighting controls (toff,controls and/
or tdim,controls, as applicable) shall not exceed 8 hours.
    1.3.2.1.ii. If using a physical test to determine the daily energy 
consumption, turn off the lights for a time period equivalent to 
toff and dim the lights for a time period equal to 
tdim. If night curtains are also being tested on the case, 
the period of lights off and/or

[[Page 830]]

dimmed shall begin at the same time that the night curtain is being 
deployed and shall continue consecutively, in that order, for the 
appropriate number of hours.
    1.3.2.1.iii. If using a calculation method to determine the daily 
energy consumption--
[GRAPHIC] [TIFF OMITTED] TR21AP14.005

    Where EER represents the energy efficiency ratio from Table 1 in 
AHRI Standard 1200 (I-P)-2010 (incorporated by reference, see Sec. 
431.63) for remote condensing equipment or the values shown in the 
following table for self-contained equipment:

EER for Self-Contained Commercial Refrigerated Display Merchandisers and
                            Storage Cabinets
------------------------------------------------------------------------
                Operating temperature class                   EER Btu/W

Low........................................................            7
Ice Cream..................................................            5
------------------------------------------------------------------------

    1.3.2.1.iii.C. For remote condensing units, calculate the revised 
compressor energy consumption (CECR) by adding the 
CECA to the compressor energy consumption (CEC) measured in 
AHRI Standard 1200 (I-P)-2010 (incorporated by reference, see Sec. 
431.63). The CDEC for the entire case is the sum of the CECR 
and LECsc (as calculated above) and the fan energy 
consumption (FEC), anti-condensate energy consumption (AEC), defrost 
energy consumption (DEC), and condensate evaporator pan energy 
consumption (PEC) (as measured in AHRI Standard 1200 (I-P)-2010).
    1.3.2.1.iii.D. For self-contained units, the TDEC for the entire 
case is the sum of total daily energy consumption as measured by the 
AHRI Standard 1200 (I-P)-2010 (incorporated by reference, see Sec. 
431.63) test with the lights fully on (TDECo) and 
CECA, less the decrease in lighting energy use due to 
lighting occupancy sensors and scheduled lighting controls, as shown in 
following equation.
[GRAPHIC] [TIFF OMITTED] TR21AP14.006

    1.3.3. Customer display signs/lights. Do not energize supplemental 
lighting that exists solely for the purposes of advertising or drawing 
attention to the case and is not integral to the operation of the case.
    1.3.4. Condensate pan heaters and pumps. For self-contained 
equipment only, all electric resistance condensate heaters and 
condensate pumps must be installed and in operation during the test. 
This includes the stabilization period (including pull-down), steady-
state, and performance testing periods. Prior to the start of the 
stabilization period as defined by ASHRAE 72-2005 (incorporated by 
reference, see Sec. 431.63), the condensate pan must be dry. Following 
the start of the stabilization period, allow any condensate moisture 
generated to accumulate in the pan. Do not manually add or remove water 
to or from the condensate pan at any time during the test.
    1.3.5. Anti-sweat door heaters. Anti-sweat door heaters must be 
operational during the entirety of the test procedure. Models with a 
user-selectable setting must have the heaters energized and set to the 
maximum usage

[[Page 831]]

position. Models featuring an automatic, non-user-adjustable controller 
that turns on or off based on environmental conditions must be operating 
in the automatic state. If a unit is not shipped with a controller from 
the point of manufacture and is intended to be used with an automatic, 
non-user-adjustable controller, test the unit with a manufacturer-
recommended controller that turns on or off based on environmental 
conditions.
    1.3.6. Ultraviolet lights. Do not energize ultraviolet lights during 
the test.
    1.3.7. Illuminated temperature displays and alarms. All illuminated 
temperature displays and alarms shall be energized and operated during 
the test as they would be during normal field operation.
    1.3.8. Condenser filters. Remove any nonpermanent filters that are 
provided to prevent particulates from blocking a model's condenser coil.
    1.3.9. Refrigeration system security covers. Remove any devices used 
to secure the condensing unit against unwanted removal.
    1.3.10. Night curtains and covers. For display cases sold with night 
curtains installed, the night curtain shall be employed for 6 hours; 
beginning 3 hours after the start of the first defrost period. Upon the 
completion of the 6-hour period, the night curtain shall be raised until 
the completion of the 24-hour test period.
    1.3.11. Grill options. Remove any optional non-standard grills used 
to direct airflow.
    1.3.12. Misting or humidification systems. Misting or humidification 
systems must be inactive during the test.
    1.3.13. Air purifiers. Air purifiers must be inactive during the 
test.
    1.3.14. General purpose outlets. During the test, do not connect any 
external load to any general purpose outlets contained within a unit.
    1.3.15. Crankcase heaters. Crankcase heaters must be operational 
during the test. If a control system, such as a thermostat or electronic 
controller, is used to modulate the operation of the crankcase heater, 
it must be utilized during the test.
    1.3.16. Drawers. Drawers are to be treated as identical to doors 
when conducting the DOE test procedure. Commercial refrigeration 
equipment with drawers should be configured with the drawer pans that 
allow for the maximum packing of test simulators and filler packages 
without the filler packages and test simulators exceeding 90 percent of 
the refrigerated volume. Packing of test simulators and filler packages 
shall be in accordance with the requirements for commercial 
refrigerators without shelves, as specified in section 6.2.3 of ASHRAE 
72-2005 (incorporated by reference, see Sec. 431.63).

                           2. Test Conditions

    2.1. Integrated Average Temperatures. Conduct the testing required 
in section 1 of this appendix B, and determine the daily energy 
consumption at the applicable integrated average temperature in the 
following table.

    2.2. Lowest Application Product Temperature. If a unit of commercial 
refrigeration equipment is not able to be operated at the integrated 
average temperature specified in the table in paragraph 2.1 of this 
appendix, test the unit at the lowest application product temperature 
(LAPT), as defined in Sec. 431.62. For units equipped with a 
thermostat, LAPT is the lowest thermostat setting. For remote condensing 
equipment without a thermostat or other means of controlling temperature 
at the case, the lowest application product temperature is the 
temperature achieved with the dew point temperature (as defined in AHRI 
Standard 1200 (I-P)-2010 (incorporated by reference, see Sec. 431.63)) 
set to 5

[[Page 832]]

degrees colder than that required to maintain the manufacturer's lowest 
specified application temperature.
    2.3. Testing at NSF Test Conditions. For commercial refrigeration 
equipment that is also tested in accordance with NSF test procedures 
(Type I and Type II), integrated average temperatures and ambient 
conditions used for NSF testing may be used in place of the DOE-
prescribed integrated average temperatures and ambient conditions 
provided they result in a more stringent test. That is, the measured 
daily energy consumption of the same unit, when tested at the rating 
temperatures and/or ambient conditions specified in the DOE test 
procedure, must be lower than or equal to the measured daily energy 
consumption of the unit when tested with the rating temperatures or 
ambient conditions used for NSF testing. The integrated average 
temperature measured during the test may be lower than the range 
specified by the DOE applicable temperature specification provided in 
paragraph 2.1 of this appendix, but may not exceed the upper value of 
the specified range. Ambient temperatures and/or humidity values may be 
higher than those specified in the DOE test procedure.

                    3. Volume and Total Display Area

    3.1. Determination of Volume. Determine the volume of a commercial 
refrigerator, freezer, refrigerator-freezer, or ice-cream freezer using 
the method set forth in the HRF-1-2008 (incorporated by reference, see 
Sec. 431.63), section 3.30, ``Volume,'' and sections 4.1 through 4.3, 
``Method for Computing Refrigerated Volume of Refrigerators, 
Refrigerator-Freezers, Wine Chillers and Freezers.''
    3.2. Determination of Total Display Area. Determine the total 
display area of a commercial refrigerator, freezer, refrigerator-
freezer, or ice-cream freezer using the method set forth in ARI Standard 
1200-2006 (incorporated by reference, see Sec. 431.63), but 
disregarding the specification that ``transparent material 
(=65% light transmittance) in Appendix D. Specifically, total 
display area shall be the sum of the projected area(s) of visible 
product, expressed in ft\2\ (i.e., portions through which product can be 
viewed from an angle normal, or perpendicular, to the transparent area). 
Determine L as the interior length of the CRE model, provided no more 
than 5 inches of that length consists of non-transparent material. For 
those cases with greater than 5 inches of non-transparent area, L shall 
be determined as the projected linear dimension(s) of visible product 
plus 5 inches of non-transparent area.
    See Figures A3.1, A3.2, and A3.3 as examples of how to calculate the 
dimensions associated with calculation of total display area. In the 
diagrams, Dh and L represent the dimensions of the projected 
visible product.

Sec. 431.76  Uniform test method for the measurement of energy
efficiency of commercial warm air furnaces.

    (a) Scope. This section covers the test requirements used to measure 
the energy efficiency of commercial warm air furnaces with a rated 
maximum input of 225,000 Btu per hour or more. On and after July 11, 
2016, any representations made with respect to the energy use or 
efficiency of commercial warm air furnaces must be made in accordance 
with the results of testing pursuant to this section. At that time, you 
must use the relevant procedures in ANSI Z21.47 or UL 727-2006 
(incorporated by reference, see Sec. 431.75). On and after August 17, 
2015 and prior to July 11, 2016, manufacturers must test commercial warm 
air furnaces in accordance with this amended section or the section as 
it appeared at 10 CFR part 430, subpart B in the 10 CFR parts 200 to 499 
edition revised January 1, 2014. DOE notes that, because testing under 
this section is required as of July 11, 2016, manufacturers may wish to 
begin using this amended test procedure immediately. Any representations 
made with respect to the energy use or efficiency of such commercial 
warm air furnaces must be made in accordance with whichever version is 
selected.
    (b) Testing. Where this section prescribes use of ANSI Z21.47 or UL 
727-2006 (incorporated by reference, see Sec. 431.75), perform only the 
procedures pertinent to the measurement of the steady-state efficiency, 
as specified in paragraph (c) of this section.
    (c) Test set-up. (1) Test set-up for gas-fired commercial warm air 
furnaces. The test set-up, including flue requirement, instrumentation, 
test conditions, and measurements for determining thermal efficiency is 
as specified in sections 1.1 (Scope), 2.1 (General), 2.2 (Basic Test 
Arrangements), 2.3 (Test Ducts and Plenums), 2.4 (Test Gases), 2.5 (Test 
Pressures and Burner Adjustments), 2.6 (Static Pressure and Air Flow 
Adjustments), 2.39 (Thermal Efficiency), and 4.2.1 (Basic Test 
Arrangements for Direct Vent Central Furnaces) of ANSI Z21.47 
(incorporated by reference, see Sec. 431.75). The thermal efficiency 
test must be conducted only at the normal inlet test pressure, as 
specified in section 2.5.1 of ANSI Z21.47, and at the maximum hourly Btu 
input rating specified by the manufacturer for the product being tested.
    (2) Test setup for oil-fired commercial warm air furnaces. The test 
setup, including flue requirement, instrumentation, test conditions, and 
measurement for measuring thermal efficiency is as specified in sections 
1 (Scope), 2 (Units of Measurement), 3 (Glossary), 37 (General), 38 and 
39 (Test Installation), 40 (Instrumentation, except 40.4 and 40.6.2 
through 40.6.7, which are not required for the thermal efficiency test), 
41 (Initial Test Conditions), 42 (Combustion Test--Burner and Furnace), 
43.2 (Operation Tests), 44 (Limit Control Cutout Test), 45 (Continuity 
of Operation Test), and 46 (Air Flow, Downflow or Horizontal Furnace 
Test), of UL 727-2006 (incorporated by reference, see Sec. 431.75). You 
must conduct a fuel oil analysis for heating value, hydrogen content, 
carbon content, pounds per gallon, and American Petroleum Institute 
(API) gravity as specified in section 8.2.2 of HI BTS-2000 (incorporated

[[Page 837]]

by reference, see Sec. 431.75). The steady-state combustion conditions, 
specified in Section 42.1 of UL 727-2006, are attained when variations 
of not more than 5 [deg]F in the measured flue gas temperature occur for 
three consecutive readings taken 15 minutes apart.
    (d) Additional test measurements--(1) Measurement of flue 
CO2 (carbon dioxide) for oil-fired commercial warm air 
furnaces. In addition to the flue temperature measurement specified in 
section 40.6.8 of UL 727-2006 (incorporated by reference, see Sec. 
431.75), you must locate one or two sampling tubes within six inches 
downstream from the flue temperature probe (as indicated on Figure 40.3 
of UL 727-2006). If you use an open end tube, it must project into the 
flue one-third of the chimney connector diameter. If you use other 
methods of sampling CO2, you must place the sampling tube so 
as to obtain an average sample. There must be no air leak between the 
temperature probe and the sampling tube location. You must collect the 
flue gas sample at the same time the flue gas temperature is recorded. 
The CO2 concentration of the flue gas must be as specified by 
the manufacturer for the product being tested, with a tolerance of 
0.1 percent. You must determine the flue 
CO2 using an instrument with a reading error no greater than 
0.1 percent.
    (2) Procedure for the measurement of condensate for a gas-fired 
condensing commercial warm air furnace. The test procedure for the 
measurement of the condensate from the flue gas under steady-state 
operation must be conducted as specified in sections 7.2.2.4, 7.8, and 
9.2 of ASHRAE 103 (incorporated by reference, see Sec. 431.75) under 
the maximum rated input conditions. You must conduct this condensate 
measurement for an additional 30 minutes of steady-state operation after 
completion of the steady-state thermal efficiency test specified in 
paragraph (c) of this section.
    (e) Calculation of thermal efficiency --(1) Gas-fired commercial 
warm air furnaces. You must use the calculation procedure specified in 
section 2.39, Thermal Efficiency, of ANSI Z21.47 (incorporated by 
reference, see Sec. 431.75).
    (2) Oil-fired commercial warm air furnaces. You must calculate the 
percent flue loss (in percent of heat input rate) by following the 
procedure specified in sections 11.1.4, 11.1.5, and 11.1.6.2 of the HI 
BTS-2000 (incorporated by reference, see Sec. 431.75). The thermal 
efficiency must be calculated as: Thermal Efficiency (percent) = 100 
percent - flue loss (in percent).
    (f) Procedure for the calculation of the additional heat gain and 
heat loss, and adjustment to the thermal efficiency, for a condensing 
commercial warm air furnace. (1) You must calculate the latent heat gain 
from the condensation of the water vapor in the flue gas, and calculate 
heat loss due to the flue condensate down the drain, as specified in 
sections 11.3.7.1 and 11.3.7.2 of ASHRAE 103 (incorporated by reference, 
see Sec. 431.75), with the exception that in the equation for the heat 
loss due to hot condensate flowing down the drain in section 11.3.7.2, 
the assumed indoor temperature of 70 [deg]F and the temperature term 
TOA must be replaced by the measured room temperature as 
specified in section 2.2.8 of ANSI Z21.47 (incorporated by reference, 
see Sec. 431.75).
    (2) Adjustment to the thermal efficiency for condensing furnaces. 
You must adjust the thermal efficiency as calculated in paragraph (e)(1) 
of this section by adding the latent gain, expressed in percent, from 
the condensation of the water vapor in the flue gas, and subtracting the 
heat loss (due to the flue condensate down the drain), also expressed in 
percent, both as calculated in paragraph (f)(1) of this section, to 
obtain the thermal efficiency of a condensing furnace.

boiler for thermal efficiency testing according to the provisions of 
Section C2 (except section C2.1) of Appendix C of ANSI/AHRI Standard 
1500-2015 (incorporated by reference, see Sec. 431.85).
    2.1.4.1. For tests of oil-fired commercial packaged boilers, 
determine the weight of fuel consumed using one of the methods specified 
in the following sections 2.1.4.1.1. or 2.1.4.1.2. of this appendix:
    2.1.4.1.1. If using a scale, determine the weight of fuel consumed 
as the difference between the weight of the oil vessel before and after 
each measurement period, as specified in sections 2.1.4.1.3.1. or 
2.1.4.1.3.2. of this appendix, determined using a scale meeting the 
accuracy requirements of Table C1 of Appendix C of ANSI/AHRI Standard 
1500-2015.
    2.1.4.1.2. If using a flow meter, first determine the volume of fuel 
consumed as the total volume over the applicable measurement period as 
specified in 2.1.4.1.3.1. or 2.1.4.1.3.2. of this appendix and as 
measured by a flow meter meeting the accuracy requirements of Table C1 
of Appendix C of ANSI/AHRI Standard 1500-2015 upstream of the oil inlet 
port of the commercial packaged boiler. Then determine the weight of 
fuel consumed by multiplying the total volume of fuel over the 
applicable measurement period by the density of oil as determined 
pursuant to C3.2.1.1.3. of Appendix C of ANSI/AHRI Standard 1500-2015.
    2.1.4.1.3. The applicable measurement period for the purposes of 
determining fuel input rate must be as specified in section 2.1.4.1.3.1. 
of this appendix for the ``Warm-Up Period'' or section 2.1.4.1.3.2. of 
this appendix for the ``Test Period.''
    2.1.4.1.3.1. For the purposes of confirming steady-state operation 
during the ``Warm-Up Period,'' the measurement period must be 15 minutes 
and tT in Equation C2 in Section C7.2.3.1 of Appendix C of 
ANSI/AHRI Standard 1500-2015 must be 0.25 hours to determine fuel input 
rate.
    2.1.4.1.3.2. For the purposes of determining thermal efficiency 
during the ``Test Period,'' the measurement period and tT are 
as specified in sections 2.3.4 and 2.3.5 of this appendix.
    2.1.4.2 For tests of gas-fired commercial packaged boilers, install 
a volumetric gas meter meeting the accuracy requirements of Table C1 of 
Appendix C of ANSI/AHRI Standard 1500-2015 upstream of the gas inlet 
port of the commercial packaged boiler. Record the accumulated gas 
volume consumed for each applicable measurement period. Use Equation 
C7.2.3.2. of Appendix C of ANSI/AHRI Standard 1500-2015 to calculate 
fuel input rate.
    2.1.4.2.1. The applicable measurement period for the purposes of 
determining fuel input rate must be as specified in section 2.1.4.2.1.1. 
of this appendix for the ``Warm-Up Period'' and 2.1.4.2.1.2. of this 
appendix for the ``Test Period.''
    2.1.4.2.1.1. For the purposes of confirming steady-state operation 
during the ``Warm-Up Period,'' the measurement period must be 15 minutes 
and tT in Equation C2 in Section C7.2.3.1 of Appendix C of 
ANSI/AHRI Standard 1500-2015 must be 0.25 hours to determine fuel input 
rate.
    2.1.4.2.1.2. For the purposes of determining thermal efficiency 
during the ``Test Period,'' the measurement period and tT are 
as specified in sections 2.3.4 and 2.3.5 of this appendix.
    2.1.4.3 In addition to the provisions of Section C2.2.1.2 of ANSI/
AHRI Standard 1500-2015, vent gases may alternatively be discharged 
vertically into a straight stack section without elbows. R-7 minimum 
insulation must extend 6 stack diameters above the flue collar, the 
thermocouple grid must be located at a vertical distance of 3 stack 
diameters above the flue collar, and the sampling tubes for flue gases 
must be installed within 1 stack diameter beyond the thermocouple grid. 
If dilution air is introduced into the flue gases before the plane of 
the thermocouple and flue gas sampling points, utilize an alternate 
plane of thermocouple grid and flue gas sampling point located 
downstream from the heat exchanger and upstream from the point of 
dilution air introduction.
    2.1.5. Additional Requirements for Outdoor Commercial Packaged 
Boilers. If the manufacturer provides more than one outdoor venting 
arrangement, the outdoor commercial packaged boiler (as defined in 
Section 3.2.6 of ANSI/AHRI Standard 1500-2015; incorporated by 
reference, see Sec. 431.85) must be tested with the shortest total 
venting arrangement as measured by adding the straight lengths of 
venting supplied with the equipment. If the manufacturer does not 
provide an outdoor venting arrangement, install the outdoor commercial 
packaged boiler venting consistent with the procedure specified in 
Section C2.2 of Appendix C of ANSI/AHRI Standard 1500-2015.
    2.1.6. Additional Requirements for Steam Tests. In addition to the 
provisions of Section C2 of Appendix C of ANSI/AHRI Standard 1500-2015 
(incorporated by reference, see Sec. 431.85), the following 
requirements apply for steam tests.
    2.1.6.1. Insulate all steam piping from the commercial packaged 
boiler to the steam separator, and extend insulation at least one foot 
(1 ft.) beyond the steam separator, using insulation meeting the 
requirements specified in Table 2.3 of this appendix.

[[Page 845]]

[GRAPHIC] [TIFF OMITTED] TR09DE16.024

    2.1.6.2. A temperature sensing device must be installed in the 
insulated steam piping prior to the water separator if the commercial 
packaged boiler produces superheated steam.
    2.1.6.3. Water entrained in the steam and water condensing within 
the steam piping must be collected and used to calculate the quality of 
steam during the ``Test Period.'' Steam condensate must be collected and 
measured using either a cumulative (totalizing) flow rate or by 
measuring the mass of the steam condensate. Instrumentation used to 
determine the amount of steam condensate must meet the requirements 
identified in Table C1 in Appendix C of ANSI/AHRI Standard 1500-2015.
    2.1.7. Additional Requirements for Water Tests. In addition to the 
provisions of section C2 of Appendix C of ANSI/AHRI Standard 1500-2015 
(incorporated by reference, see Sec. 431.85), the following 
requirements apply for water tests.
    2.1.7.1. Insulate all water piping between the commercial packaged 
boiler and the location of the temperature measuring equipment, 
including one foot (1 ft.) beyond the sensor, using insulation meeting 
the requirements specified in Table 2.3 of this appendix.
    2.1.7.2. Install a temperature measuring device at Point B of Figure 
C9 of ANSI/AHRI Standard 1500-2015 (incorporated by reference, see Sec. 
431.85). Water entering the commercial packaged boiler must first enter 
the run of a tee and exit from the top outlet of the tee. The remaining 
connection of the tee must be plugged. Measure the inlet water 
temperature at Point B in the run of a second tee located 12  2 pipe diameters downstream from the first tee and no 
more than the greater of 12 inches or 6 pipe diameters from the inlet of 
the commercial packaged boiler. The temperature measuring device shall 
extend into the water flow at the point of exit from the side outlet of 
the second tee. All inlet piping between the temperature measuring 
device and the inlet of the commercial packaged boilers must be wrapped 
with R-7 insulation.
    2.1.7.3. Do not use Section C2.7.2.2.2 or its subsections of ANSI/
AHRI Standard 1500-2015 for water meter calibration.
    2.1.8. Flue Gas Sampling. In section C2.5.2 of Appendix C of ANSI/
AHRI Standard 1500-2015, replace the last sentence with the following: 
When taking flue gas samples from a rectangular plane, collect samples 
at \1/4\, \1/2\, and \3/4\ the distance from one side of the rectangular 
plane in the longer dimension and along the centerline midway between 
the edges of the plane in the shorter dimension and use the average of 
the three samples. The tolerance in each dimension for each measurement 
location is  1 inch.
    2.2. Test Conditions.
    2.2.1. General. Use the test conditions from Section 5 and Section 
C3 of Appendix C of ANSI/AHRI Standard 1500-2015 (incorporated by 
reference, see Sec. 431.85) for thermal efficiency testing but do not 
use the following sections:

    2.2.2. Burners for Oil-Fired Commercial Packaged Boilers. In 
addition to section C3.3 of Appendix C of ANSI/AHRI Standard 1500-2015, 
the following applies: For oil-fired commercial packaged boilers, test 
the unit with the particular make and model of burner as certified (or 
to be certified) by the manufacturer. If multiple burners are specified 
in the certification report for that basic model, then use any of the 
listed burners for testing.
    2.2.3. Water Temperatures. Maintain the outlet temperature measured 
at Point C in Figure C9 of Appendix C of ANSI/AHRI Standard 1500-2015 at 
180 [deg]F  2 [deg]F and maintain the inlet 
temperature measured at Point B at 80 [deg]F  5 
[deg]F during the ``Warm-up

Period'' and ``Test Period'' as indicated by 1-minute interval data 
pursuant to Table 2.2 of this appendix. Each reading must meet these 
temperature requirements. Use the inlet temperature and flow rate 
measured at Point B in Figure C9 of Appendix C of ANSI/AHRI Standard 
1500-2015 for calculation of thermal efficiency.
    2.2.4 Exceptions to Water Temperature Requirements. For commercial 
packaged boilers that require a higher flow rate than that resulting 
from the water temperature requirements of sections 2.2.3 of this 
appendix to prevent boiling, use a recirculating loop and maintain the 
inlet temperature at Point B of Figure C9 of Appendix C of ANSI/AHRI 
Standard 1500-2015 at 140 [deg]F  5 [deg]F during 
the ``Warm-up Period'' and ``Test Period'' as indicated by 1-minute 
interval data pursuant to Table 2.2 of this appendix. Each reading must 
meet these temperature requirements. Use the inlet temperature and flow 
rate measured at Point A in Figure C9 of Appendix C of ANSI/AHRI 
Standard 1500-2015 for calculation of thermal efficiency.
    2.2.5 Air Temperature. For tests of non-condensing boilers, maintain 
ambient room temperature between 65 [deg]F and 100 [deg]F at all times 
during the ``Warm-up Period'' and ``Test Period'' (as described in 
Section C4 of Appendix C of ANSI/AHRI Standard 1500-2015) as indicated 
by 1-minute interval data pursuant to Table 2.2 of this appendix. For 
tests of condensing boilers, maintain ambient room temperature between 
65 [deg]F and 85 [deg]F at all times during the ``Warm-up Period'' and 
``Test Period'' (as described in Section C4 of Appendix C of ANSI/AHRI 
Standard 1500-2015) as indicated by 1-minute interval data pursuant to 
Table 2.2 of this appendix. The ambient room temperature may not differ 
by more than  5 [deg]F from the average ambient 
room temperature during the entire ``Test Period'' at any reading. 
Measure the room ambient temperature within 6 feet of the front of the 
unit at mid height. The test air temperature, measured at the air inlet 
of the commercial packaged boiler, must be within  
5 [deg]F of the room ambient temperature when recorded at the 1-minute 
interval defined by Table 2.2 of this appendix.
    2.2.6. Ambient Humidity. For condensing boilers, maintain ambient 
room relative humidity below 80-percent at all times during both the 
``Warm-up Period'' and ``Test Period'' (as described in Section C4 of 
Appendix C of ANSI/AHRI Standard 1500-2015) pursuant to Table 2.2 of 
this appendix. Measure the ambient humidity in the same location as 
ambient air temperature in section 2.2.5 of this appendix.
    2.2.7. Flue Gas Temperature. The flue gas temperature during the 
test must not vary from the flue gas temperature measured at the start 
of the Test Period (as defined in Section C4 of ANSI/AHRI Standard 1500-
2015) when recorded at the interval defined in Table 2.2 of this 
appendix by more than the limits prescribed in Table 2.4 of this

    2.3. Test Method.
    2.3.1. General. Conduct the thermal efficiency test as prescribed in 
Section C4 ``Test Procedure'' of Appendix C of ANSI/AHRI Standard 1500-
2015 (incorporated by reference, see Sec. 431.85) excluding sections:

(1) C4.1.1.1.2 (see section 2.3.1.1 of this appendix)
(2) C4.1.1.2.3 (see 2.3.4 of this appendix)
(3) C4.1.2.1.5 (see section 2.3.2. of this appendix)
(4) C4.1.2.2.2
(5) C4.1.2.2.3 (see 2.3.5 of this appendix)
(6) C4.2
(7) C4.2.1
(8) C4.2.2

    2.3.1.1. Adjust oil or non-atmospheric gas to produce the required 
firebox pressure and CO2 or O2 concentration in 
the flue gas, as described in Section 5.3.1 of ANSI/AHRI Standard 1500-
2015. Conduct steam tests with steam pressure at the pressure specified 
in the manufacturer literature shipped with the commercial packaged 
boiler or in the manufacturer's supplemental testing instructions 
pursuant to Sec. 429.60(b)(4) of this chapter, but not exceeding 15 
psig. If no pressure is specified in the manufacturer literature shipped 
with the commercial packaged boiler or in the manufacturer's 
supplemental testing instructions (pursuant to Sec. 429.60(b)(4) of 
this chapter), or if a range of operating pressures is specified, 
conduct testing at a steam pressure equal to atmospheric pressure. If 
necessary to maintain steam quality as required by Section 5.3.7 of 
ANSI/AHRI Standard 1500-2015, increase steam pressure in 1 psig 
increments by throttling with a valve beyond the separator until the 
test is completed and the steam quality requirements have been 
satisfied, but do not increase the steam pressure to greater than 15 
psig.

[[Page 847]]

    2.3.2. Water Test Steady-State. Ensure that a steady-state is 
reached by confirming that three consecutive readings have been recorded 
at 15-minute intervals pursuant to Table 2.2 of this appendix that 
indicate that the measured fuel input rate is within  2-percent of the rated input. Water temperatures must 
meet the conditions specified in sections 2.2.3 and 2.2.4 of this 
appendix as applicable.
    2.3.3. Condensate Collection for Condensing Commercial Packaged 
Boilers. Collect condensate in a covered vessel so as to prevent 
evaporation.
    2.3.4. Steam Test Duration. Replace Section C4.1.1.2.3 of ANSI/AHRI 
Standard 1500-2015 with the following: The test period is one hour in 
duration if the steam condensate is measured or two hours if feedwater 
is measured. The test period must end with a 15-minute reading (steam 
condensate or feedwater and separator weight reading) pursuant to Table 
2.2 of this appendix. When feedwater is measured, the water line at the 
end of the test must be within 0.25 inches of the starting level.
    2.3.5. Water Test Duration. Replace Section C4.1.2.2.3 of ANSI/AHRI 
Standard 1500-2015 with the following: The test period is one hour for 
condensing commercial packaged boilers and 30 minutes for non-condensing 
commercial packaged boilers, and ends with a 15-minute interval reading 
pursuant to Table 2.2 of this appendix.
    2.4. Calculations.
    2.4.1. General. To determine the thermal efficiency of commercial 
packaged boilers, use the variables in section C6 of Appendix C of ANSI/
AHRI Standard 1500-2015 and calculation procedure for the thermal 
efficiency test specified in section C7.2 of Appendix C of ANSI/AHRI 
Standard 1500-2015, excluding sections C7.2.12 and C7.2.20.
    2.4.2. Use of Steam Properties Table. If the average measured 
temperature of the steam is higher than the value in Table D1 in 
Appendix D of ANSI/AHRI Standard 1500-2015 that corresponds to the 
average measured steam pressure, then use Table 2.5 of this appendix to 
determine the latent heat of superheated steam in (Btu/lb). Use linear 
interpolation for determining the latent heat of steam in Btu/lb if the 
measured steam pressure is between two values listed in Table D1 in 
Appendix D of ANSI/AHRI Standard 1500-2015 or in Table 2.5 of this 
appendix.

    3.1.3. Instrument Calibration. Instruments must be calibrated at 
least once per year and a calibration record, containing at least the 
date of calibration and the method of calibration, must be kept as part 
of the data underlying each basic model certification, pursuant to Sec. 
429.71 of this chapter.

[[Page 852]]

    3.1.4. Test Setup and Apparatus. Set up the commercial packaged 
boiler for combustion efficiency testing according to the provisions of 
Section C2 (except section C2.1) of Appendix C of ANSI/AHRI Standard 
1500-2015.
    3.1.4.1. For tests of oil-fired commercial packaged boilers, 
determine the weight of fuel consumed using one of the methods specified 
in sections 3.1.4.1.1. or 3.1.4.1.2. of this appendix:
    3.1.4.1.1. If using a scale, determine the weight of fuel consumed 
as the difference between the weight of the oil vessel before and after 
each measurement period, as specified in sections 3.1.4.1.3.1. or 
3.1.4.1.3.2. of this appendix, determined using a scale meeting the 
accuracy requirements of Table C1 of ANSI/AHRI Standard 1500-2015.
    3.1.4.1.2. If using a flow meter, first determine the volume of fuel 
consumed as the total volume over the applicable measurement period, as 
specified in sections 3.1.4.1.3.1. or 3.1.4.1.3.2. of this appendix, and 
as measured by a flow meter meeting the accuracy requirements of Table 
C1 of ANSI/AHRI Standard 1500-2015 upstream of the oil inlet port of the 
commercial packaged boiler. Then determine the weight of fuel consumed 
by multiplying the total volume of fuel over the applicable measurement 
period by the density of oil, in pounds per gallon, as determined 
pursuant to Section C3.2.1.1.3. of ANSI/AHRI Standard 1500-2015.
    3.1.4.1.3. The applicable measurement period for the purposes of 
determining fuel input rate must be as specified in section 3.1.4.1.3.1. 
of this appendix for the ``Warm-Up Period'' or 3.1.4.1.3.2. of this 
appendix for the ``Test Period.''
    3.1.4.1.3.1. For the purposes of confirming steady-state operation 
during the ``Warm-Up Period,'' the measurement period must be 15 minutes 
and tT in Equation C2 in Section C7.2.3.1 of ANSI/AHRI 
Standard 1500-2015 must be 0.25 hours to determine fuel input rate.
    3.1.4.1.3.2. For the purposes of determining combustion efficiency 
during the ``Test Period,'' the measurement period and tT are 
0.5 hours pursuant to section 3.3.1.1. of this appendix.
    3.1.4.2 For tests of gas-fired commercial packaged boilers, install 
a volumetric gas meter meeting the accuracy requirements of Table C1 of 
ANSI/AHRI Standard 1500-2015 upstream of the gas inlet port of the 
commercial packaged boiler. Record the accumulated gas volume consumed 
for each applicable measurement period. Use Equation C7.2.3.2. of ANSI/
AHRI Standard 1500-2015 to calculate fuel input rate.
    3.1.4.2.1. The applicable measurement period for the purposes of 
determining fuel input rate must be as specified in section 3.1.4.2.1.1. 
of this appendix for the ``Warm-Up Period'' and 3.1.4.2.1.2. of this 
appendix for the ``Test Period.''
    3.1.4.2.1.1. For the purposes of confirming steady-state operation 
during the ``Warm-Up Period,'' the measurement period must be 15 minutes 
and tT in Equation C2 in Section C7.2.3.1 of ANSI/AHRI 
Standard 1500-2015 must be 0.25 hour to determine fuel input rate.
    3.1.4.2.1.2. For the purposes of determining combustion efficiency 
during the ``Test Period,'' the measurement period and tT are 
0.5 hour pursuant to section 3.3.1.1. of this appendix.
    3.1.4.3. In addition to the provisions of Section C2.2.1.2 of ANSI/
AHRI Standard 1500-2015, vent gases may alternatively be discharged 
vertically into a straight stack section without elbows. R-7 minimum 
insulation must extend 6 stack diameters above the flue collar, the 
thermocouple grid must be located at a vertical distance of 3 stack 
diameters above the flue collar, and the sampling tubes for flue gases 
must be installed within 1 stack diameter beyond the thermocouple grid. 
If dilution air is introduced into the flue gases before the plane of 
the thermocouple and flue gas sampling points, utilize an alternate 
plane of thermocouple grid and flue gas sampling point located 
downstream from the heat exchanger and upstream from the point of 
dilution air introduction.
    3.1.5. Additional Requirements for Outdoor Commercial Packaged 
Boilers. If the manufacturer provides more than one outdoor venting 
arrangement, the outdoor commercial packaged boiler (as defined in 
section 3.2.6 of ANSI/AHRI Standard 1500-2015 (incorporated by 
reference, see Sec. 431.85) must be tested with the shortest total 
venting arrangement as measured by adding the straight lengths of 
venting supplied with the equipment. If the manufacturer does not 
provide an outdoor venting arrangement, install the outdoor commercial 
packaged boiler venting consistent with the procedure specified in 
Section C2.2 of Appendix C of ANSI/AHRI Standard 1500-2015.
    3.1.6. Additional Requirements for Field Tests.
    3.1.6.1 Field tests are exempt from the requirements of Section C2.2 
of Appendix C of ANSI/AHRI Standard 1500-2015. Measure the flue gas 
temperature according to Section C2.5.1 of Appendix C of ANSI/AHRI 
Standard 1500-2015 and the thermocouple grids identified in Figure C12 
of ANSI/AHRI Standard 1500-2015, with the following modification: the 
thermocouple grid may be staggered vertically by up to 1.5 inches to 
allow the use of instrumented rods to be inserted through holes drilled 
in the venting.
    3.1.6.2. Field tests are exempt from the requirements of Section 
C2.6.3 of Appendix C of ANSI/AHRI Standard 1500-2015.

provisions of Section C2 of Appendix C of ANSI/AHRI Standard 1500-2015 
(incorporated by reference, see

[[Page 853]]

Sec. 431.85) the following requirements apply for water tests:
    3.1.7.1. Insulate all water piping between the commercial packaged 
boiler and the location of the temperature measuring equipment, 
including one foot (1 ft.) beyond the sensor, using insulation meeting 
the requirements specified in Table 2.3 of this appendix.
    3.1.7.2. Install a temperature measuring device at Point B of Figure 
C9 of ANSI/AHRI Standard 1500-2015. Water entering the commercial 
packaged boiler must first enter the run of a tee and exit from the top 
outlet of the tee. The remaining connection of the tee must be plugged. 
Measure the inlet water temperature at Point B in the run of a second 
tee located 12  2 pipe diameters downstream from 
the first tee and no more than the greater of 12 inches or 6 pipe 
diameters from the inlet of the commercial packaged boiler. The 
temperature measuring device shall extend into the water flow at the 
point of exit from the side outlet of the second tee. All inlet piping 
between the temperature measuring device and the inlet of the commercial 
packaged boilers must be wrapped with R-7 insulation. Field tests must 
also measure the inlet water temperature at Point B in Figure C9, 
however they are not required to use the temperature measurement piping 
described in this section 3.1.7. of this appendix.
    3.1.7.3. Do not use Section C2.7.2.2.2 or its subsections of ANSI/
AHRI Standard 1500-2015 for water meter calibration.
    3.1.8. Flue Gas Sampling. In section C2.5.2 of Appendix C of ANSI/
AHRI Standard 1500-2015, replace the last sentence with the following: 
When taking flue gas samples from a rectangular plane, collect samples 
at \1/4\, \1/2\, and \3/4\ the distance from one side of the rectangular 
plane in the longer dimension and along the centerline midway between 
the edges of the plane in the shorter dimension and use the average of 
the three samples. The tolerance in each dimension for each measurement 
location is  1 inch.
    3.2. Test Conditions.
    3.2.1. General. Use the test conditions from Sections 5 and C3 of 
Appendix C of ANSI/AHRI Standard 1500-2015 (incorporated by reference; 
see Sec. 431.85) for combustion efficiency testing but do not use the 
following sections:

(1) 5.3 Introductory text
(2) 5.3.5 (and subsections; see sections 3.2.3, 3.2.3.1, and 3.2.3.2 of 
this appendix)
(3) 5.3.7 (excluded for field tests only)

(5) 5.3.9 (see section 3.2.5 of this appendix)
(6) C3.1.3 (and subsections)
(7) C3.5 (including Table C2; see section 3.2.6 of this appendix)
(8) C3.6 (see section 3.2.4 of this appendix)
(9) C3.7 (see section 3.2.5 of this appendix)

    3.2.2. Burners for Oil-Fired Commercial Packaged Boilers. In 
addition to Section C3.3 of Appendix C of ANSI/AHRI Standard 1500-2015, 
the following applies: for oil-fired commercial packaged boilers, test 
the unit with the particular make and model of burner as certified (or 
to be certified) by the manufacturer. If multiple burners are specified 
in the certification report for that basic model, then use any of the 
listed burners for testing.
    3.2.3. Water Temperatures. Maintain the outlet temperature measured 
at Point C in Figure C9 at 180 [deg]F  2 [deg]F 
and maintain the inlet temperature measured at Point B at 80 [deg]F 
 5 [deg]F during the ``Warm-up Period'' and ``Test 
Period'' as indicated by 1-minute interval data pursuant to Table 3.2 of 
this appendix. Each reading must meet these temperature requirements. 
Field tests are exempt from this requirement and instead must comply 
with the requirements of section 3.2.3.1 of this appendix.
    3.2.3.1. For field tests, the inlet temperature measured at Point A 
and Point B in Figure C9 and the outlet temperature measured and Point C 
in Figure C9 of ANSI/AHRI Standard 1500-2015 must be recorded in the 
data underlying that model's certification pursuant to Sec. 429.71 of 
this chapter, and the difference between the inlet (measured at Point B) 
and outlet temperature (measured at Point C) must not be less than 20 
[deg]F at any point during the ``Warm-up Period'' and ``Test Period,'' 
after stabilization has been achieved, as indicated by 1-minute interval 
data pursuant to Table 3.2 of this appendix.
    3.2.3.2 For commercial packaged boilers that require a higher flow 
rate than that resulting from the water temperature requirements of 
sections 3.2.3 of this appendix to prevent boiling, use a recirculating 
loop and maintain the inlet temperature at Point B of Figure C9 of ANSI/
AHRI Standard 1500-2015 at 140 [deg]F  5 [deg]F 
during the ``Warm-up Period'' and ``Test Period'' as indicated by 1-
minute interval data pursuant to Table 3.2 of this appendix. Each 
reading must meet these temperature requirements.
    3.2.4. Air Temperature. For tests of non-condensing boilers (except 
during field tests), maintain ambient room temperature between 65 [deg]F 
and 100 [deg]F at all times during the ``Warm-up Period'' and ``Test 
Period'' (as described in Section C4 of Appendix C of ANSI/AHRI Standard 
1500-2015) as indicated by 1-minute interval data pursuant to Table 3.2 
of this appendix. For tests of condensing boilers (except during field 
tests), maintain ambient room temperature between 65 [deg]F and 85 
[deg]F at all times during the ``Warm-up Period'' and ``Test Period'' 
(as described in Section C4 of Appendix C of ANSI/AHRI Standard 1500-
2015) as indicated by 1-minute interval data pursuant to Table 3.2 of 
this appendix. The ambient room temperature may not differ by more than 
 5 [deg]F from the average ambient room 
temperature during the entire ``Test

[[Page 854]]

Period'' at any 1-minute interval reading. Measure the room ambient 
temperature within 6 feet of the front of the unit at mid height. The 
test air temperature, measured at the air inlet of the commercial 
packaged boiler, must be within  5 [deg]F of the 
room ambient temperature when recorded at the 1-minute interval defined 
by Table 3.2 of this appendix. For field tests, record the ambient room 
temperature at 1-minute intervals in accordance with Table 3.2 of this 
appendix.
    3.2.5. Ambient Humidity. For condensing boilers (except during field 
tests), maintain ambient room relative humidity below 80-percent 
relative humidity at all times during both the ``Warm-up Period'' and 
``Test Period'' (as described in Section C4 of Appendix C of ANSI/AHRI 
Standard 1500-2015) pursuant to Table 3.2 of this appendix. Measure the

    3.3. Test Method.
    3.3.1. General. Conduct the combustion efficiency test using the 
test method prescribed in Section C4 ``Test Procedure'' of Appendix C of 
ANSI/AHRI Standard 1500-2015 excluding sections:

(1) C4.1.1.1.2 (see section 3.3.1.2 of this appendix)
(2) C4.1.1.2.3
(3) C4.1.2.1.5 (see section 3.3.2 of this appendix)
(4) C4.1.2.2.2
(5) C4.1.2.2.3
(6) C4.2
(7) C4.2.1
(8) C4.2.2

    3.3.1.1. The duration of the ``Test Period'' for combustion 
efficiency outlined in sections C4.1.1.2 of Appendix C of ANSI/AHRI 
Standard 1500-2015 (incorporated by reference, see Sec. 431.85) and 
C4.1.2.2 of Appendix C of ANSI/AHRI Standard 1500-2015 is 30 minutes. 
For condensing commercial packaged boilers, condensate must be collected 
for the 30 minute Test Period.
    3.3.1.2. Adjust oil or non-atmospheric gas to produce the required 
firebox pressure and CO2 or O2 concentration in 
the flue gas, as described in section 5.3.1 of ANSI/AHRI Standard 1500-
2015. Conduct steam tests with steam pressure at the pressure specified 
in the manufacturer literature shipped with the commercial packaged 
boiler or in the manufacturer's supplemental testing instructions 
pursuant to Sec. 429.60(b)(4) of this chapter, but not exceeding 15 
psig. If no pressure is specified in the manufacturer literature shipped 
with the commercial packaged boiler or in the manufacturer's 
supplemental testing instructions (pursuant to Sec. 429.60(b)(4)) of 
this chapter, or if a range of operating pressures is specified, conduct 
testing at a steam pressure equal to atmospheric pressure. If necessary 
to maintain steam quality as required by section 5.3.7 of ANSI/AHRI 
Standard 1500-2015, increase steam pressure in 1 psig increments by 
throttling with a valve beyond the separator until the test is completed 
and the steam quality requirements have been satisfied, but do not 
increase the steam pressure to greater than 15 psig.
    3.3.2. Water Test Steady-State. Ensure that a steady-state is 
reached by confirming that three consecutive readings have been recorded 
at 15-minute intervals that indicate that the measured fuel input rate 
is within  2-percent of the rated input. Water 
temperatures must meet the conditions specified in sections 3.2.3, 
3.2.3.1, and 3.2.3.2 of this appendix as applicable.
    3.3.3. Procedure for the Measurement of Condensate for a Condensing 
Commercial Packaged Boiler. Collect flue condensate using a covered 
vessel so as to prevent evaporation. Measure the condensate from the 
flue gas during the ``Test Period.'' Flue condensate mass must be 
measured within 5 minutes after the end of the ``Test Period'' (defined 
in C4.1.1.2 and C4.1.2.2 of ANSI/AHRI Standard 1500-2015) to prevent 
evaporation loss from the sample. Determine the mass of flue condensate 
for the ``Test Period'' by subtracting the tare container weight from 
the total weight of the container and flue condensate measured at the 
end of the ''Warm-up Period.''
    3.4. Calculations.

[[Page 855]]

    3.4.1. General. To determine the combustion efficiency of commercial 
packaged boilers, use the variables in Section C6 and calculation 
procedure for the combustion efficiency test specified in Section C7.3 
of Appendix C (including the specified subsections of C7.2) of ANSI/AHRI 
Standard 1500-2015 (incorporated by reference, see Sec. 431.85).
    3.4.2. Rounding. Round the final combustion efficiency value to 
nearest one tenth of a percent.

------------------------------------------------------------------------

    (e) Additional provisions for equipment set-up. The only additional 
specifications that may be used in setting up the basic model for test 
are those set forth in the installation and operation manual shipped 
with the unit. Each unit should be set up for test in accordance with 
the manufacturer installation and operation manuals. Paragraphs (e)(1) 
through (3) of this section provide specifications for addressing key 
information typically found in the installation and operation manuals.
    (1) If a manufacturer specifies a range of superheat, sub-cooling, 
and/or refrigerant pressure in its installation and operation manual for 
a given basic model, any value(s) within that range may be used to 
determine refrigerant charge or mass of refrigerant, unless the 
manufacturer clearly specifies a rating value in its installation and 
operation manual, in which case the specified rating value shall be 
used.
    (2) The air flow rate used for testing must be that set forth in the 
installation and operation manuals being shipped to the commercial 
customer with the basic model and clearly identified as that used to 
generate the DOE performance ratings. If a rated air flow value for 
testing is not clearly identified, a value of 400 standard cubic feet 
per minute (scfm) per ton shall be used.
    (3) For VRF systems, the test set-up and the fixed compressor speeds 
(i.e., the maximum, minimum, and any intermediate speeds used for 
testing) should be recorded and maintained as part of the test data 
underlying the certified ratings that is required to be maintained under 
10 CFR 429.71.
    (f) Manufacturer involvement in assessment or enforcement testing 
for variable refrigerant flow systems. A manufacturer's representative 
will be allowed to witness assessment and/or enforcement testing for VRF 
systems. The manufacturer's representative will be allowed to inspect 
and discuss set-up only with a DOE representative and adjust only the 
modulating components during testing in the presence of a DOE 
representative that are necessary to achieve steady-state operation. 
Only previously documented specifications for set-up as specified under 
paragraphs (d) and (e) of this section will be used.
    (g) Test Procedures for Packaged Terminal Air Conditioners and 
Packaged Terminal Heat Pumps--(1) Cooling mode testing. The test method 
for testing packaged terminal air conditioners and packaged terminal 
heat pumps in cooling mode shall consist of application of the methods 
and conditions in AHRI 310/380-2014 sections 3, 4.1, 4.2, 4.3, and 4.4 
(incorporated by reference; see Sec. 431.95), and in ANSI/ASHRAE 16 
(incorporated by reference; see Sec. 431.95) or ANSI/ASHRAE 37 
(incorporated by reference; see Sec. 431.95), except that instruments 
used for measuring electricity input shall be accurate to within 0.5 percent of the quantity measured. Where definitions 
provided in AHRI 310/380-2014, ANSI/ASHRAE 16, and/or ANSI/ASHRAE 37 
conflict with the definitions provided in 10 CFR 431.92, the 10 CFR 
431.92 definitions shall be used. Where AHRI 310/380-2014 makes 
reference to ANSI/ASHRAE 16, it is interpreted as reference to ANSI/
ASHRAE 16-1983 (RA 2014).
    (2) Heating mode testing. The test method for testing packaged 
terminal heat pumps in heating mode shall consist of application of the 
methods and

[[Page 862]]

conditions in AHRI 310/380-2014 sections 3, 4.1, 4.2 (except the section 
4.2.1.2(b) reference to ANSI/ASHRAE 37), 4.3, and 4.4 (incorporated by 
reference; see Sec. 431.95), and in ANSI/ASHRAE 58 (incorporated by 
reference; see Sec. 431.95). Where definitions provided in AHRI 310/
380-2014 or ANSI/ASHRAE 58 conflict with the definitions provided in 10 
CFR 431.92, the 10 CFR 431.92 definitions shall be used. Where AHRI 310/
380-2014 makes reference to ANSI/ASHRAE 58, it is interpreted as 
reference to ANSI/ASHRAE 58-1986 (RA 2014).
    (3) Wall sleeves. For packaged terminal air conditioners and 
packaged terminal heat pumps, the unit must be installed in a wall 
sleeve with a 14 inch depth if available. If a 14 inch deep wall sleeve 
is not available, use the available wall sleeve option closest to 14 
inches in depth. The area(s) between the wall sleeve and the insulated 
partition between the indoor and outdoor rooms must be sealed to 
eliminate all air leakage through this area.
    (4) Optional pre-filling of the condensate drain pan. For packaged 
terminal air conditioners and packaged terminal heat pumps, test 
facilities may add water to the condensate drain pan of the equipment 
under test (until the water drains out due to overflow devices or until 
the pan is full) prior to conducting the test method specified by AHRI 
310/380-2014 (incorporated by reference, see Sec. 431.95). No specific 
level of water mineral content or water temperature is required for the 
water added to the condensate drain pan.
    (5) Filter selection. For packaged terminal air conditioners and 
packaged terminal heat pumps, the indoor filter used during testing 
shall be the standard or default filter option shipped with the model. 
If a particular model is shipped without a filter, the unit must be 
tested with a MERV-1 filter sized appropriately for the filter slot.

 Sec. Appendix A to Subpart F of Part 431--Uniform Test Method for the 
         Measurement of Energy Consumption of Air-Cooled Small 
(=65,000 Btu/h), Large, and Very Large Commercial Package
Air Conditioning and Heating Equipment

    Note: Prior to December 19, 2016, representations with respect to 
the energy use or efficiency of air-cooled small, large, and very large 
commercial package air conditioning and heating equipment, including 
compliance certifications, must be based on testing conducted in 
accordance with either Table 1 to Sec. 431.96 as it now appears or 
Table 1 to Sec. 431.96 as it appeared in subpart F of this part, in the 
10 CFR parts 200 through 499 edition revised as of January 1, 2015. 
After December 19, 2016, representations with respect to energy use or 
efficiency of air-cooled small, large, and very large commercial package 
air conditioning and heating equipment, including compliance 
certifications, must be based on testing conducted in accordance with 
Table 1 to Sec. 431.96 as it now appears.
    (1) Cooling mode test method. The test method for cooling mode 
consists of the methods and conditions in AHRI 340/360-2007 sections 3, 
4, and 6 (omitting section 6.3) (incorporated by reference; see Sec. 
431.95), and in

[[Page 871]]

ANSI/ASHRAE 37-2009 (incorporated by reference; see Sec. 431.95). In 
case of a conflict between AHRI 340/360-2007 or ANSI/ASHRAE 37-2009 and 
the CFR, the CFR provisions control.
    (2) Heating mode test method. The test method for heating mode 
consists of the methods and conditions in AHRI 340/360-2007 sections 3, 
4, and 6 (omitting section 6.3) (incorporated by reference; see Sec. 
431.95), and in ANSI/ASHRAE 37-2009 (incorporated by reference; see 
Sec. 431.95). In case of a conflict between AHRI 340/360-2007 or ANSI/
ASHRAE 37-2009 and the CFR, the CFR provisions control.
    (3) Minimum external static pressure. Use the certified cooling 
capacity for the basic model to choose the minimum external static 
pressure found in table 5 of section 6 of AHRI 340/360-2007 
(incorporated by reference; see Sec. 431.95) for testing.
    (4) Optional break-in period. Manufacturers may optionally specify a 
``break-in'' period, not to exceed 20 hours, to operate the equipment 
under test prior to conducting the test method in appendix A of this 
part. A manufacturer who elects to use an optional compressor break-in 
period in its certification testing must record this information 
(including the duration) as part of the information in the supplemental 
testing instructions under 10 CFR 429.43.
    (5) Additional provisions for equipment set-up. The only additional 
specifications that may be used in setting up a unit for test are those 
set forth in the installation and operation manual shipped with the 
unit. Each unit should be set up for test in accordance with the 
manufacturer installation and operation manuals. Paragraphs (5)(i) 
through (ii) of this section provide specifications for addressing key 
information typically found in the installation and operation manuals.
    (i) If a manufacturer specifies a range of superheat, sub-cooling, 
and/or refrigerant pressure in its installation and operation manual for 
a given basic model, any value(s) within that range may be used to 
determine refrigerant charge or mass of refrigerant, unless the 
manufacturer clearly specifies a rating value in its installation and 
operation manual, in which case the specified rating value shall be 
used.
    (ii) The airflow rate used for testing must be that set forth in the 
installation and operation manuals being shipped to the customer with 
the basic model and clearly identified as that used to generate the DOE 
performance ratings. If a certified airflow value for testing is not 
clearly identified, a value of 400 standard cubic feet per minute (scfm) 
per ton shall be used.
    (6) Indoor airflow testing and adjustment. (i) When testing full-
capacity cooling operation at the required external static pressure 
condition, the full-load indoor airflow rate must be within  3 percent of the certified-rated airflow at full-
capacity cooling operation. If the indoor airflow rate at the required 
minimum external pressure is outside the  3-
percent tolerance, the unit and/or test setup must be adjusted such that 
both the airflow and ESP are within the required tolerances. This 
process may include, but is not limited to, adjusting any adjustable 
motor sheaves, adjusting variable drive settings, or adjusting the code 
tester fan.
    (ii) When testing other than full-capacity cooling operation using 
the full-load indoor airflow rate (e.g., full-load heating), the full-
load indoor airflow rate must be within  3 percent 
of the certified-rated full-load cooling airflow (without regard to the 
resulting external static pressure), unless the unit is designed to 
operate at a different airflow for cooling and heating mode. If 
necessary, a test facility setup may be made in order to maintain 
airflow within the required tolerance; however, no adjustments to the 
unit under test may be made.
    (7) Condenser head pressure controls. Condenser head pressure 
controls, if typically shipped with units of the basic model by the 
manufacturer or available as an option to the basic model, must be 
active during testing.
    (8) Standard CFM. In the referenced sections of AHRI 340/360-2007 
(incorporated by reference; see Sec. 431.95), all instances of CFM 
refer to standard CFM (SCFM). Likewise, all references to airflow or air 
quantity refer to standard airflow and standard air quantity.
    (9) Capacity rating at part-load. When testing to determine EER for 
the part-load rating points (i.e. 75-percent load, 50-percent load, and 
25-percent load), if the measured capacity expressed as a percent of 
full-load capacity for a given part-load test is within three percent 
above or below the target part-load percentage, the EER calculated for 
the test may be used without any interpolation to determine IEER.
    (10) Condenser air inlet temperature for part-load testing. When 
testing to determine EER for the part-load rating points (i.e. 75-
percent load, 50-percent load, and 25-percent load), the condenser air 
inlet temperature shall be calculated (using the equation in Table 6 of 
AHRI 340/360-2007; incorporated by reference; see Sec. 431.95) for the 
target percent load rather than for the percent load measured in the 
test. Table 1 of this appendix shows the condenser air inlet temperature 
corresponding with each target percent load, as calculated using the 
equation in Table 6 of AHRI 340/360-2007.

[69 FR 61983, Oct. 21, 2004, as amended at 70 FR 60415, Oct. 18, 2005]



Sec. 431.102  Definitions concerning commercial water heaters, hot
water supply boilers, unfired hot water storage tanks, and commercial
heat pump water heaters.

    The following definitions apply for purposes of this subpart G, and 
of subparts J through M of this part. Any words or terms not defined in 
this section or elsewhere in this part shall be defined as provided in 
section 340 of the Act, 42 U.S.C. 6311.
    Air-source commercial heat pump water heater means a commercial heat 
pump water heater that utilizes indoor or outdoor air as the heat 
source.
    Basic model means all water heaters, hot water supply boilers, or 
unfired hot water storage tanks manufactured by one manufacturer within 
a single equipment class, having the same primary energy source (e.g., 
gas or oil) and that have essentially identical electrical, physical and 
functional characteristics that affect energy efficiency.
    Coefficient of performance (COPh) means the dimensionless 
ratio of the rate of useful heat transfer gained by the water (expressed 
in Btu/h), to the rate of electric power consumed during operation 
(expressed in Btu/h).
    Commercial heat pump water heater (CHPWH) means a water heater 
(including all ancillary equipment such as fans, blowers, pumps, storage 
tanks, piping, and controls, as applicable) that uses a refrigeration 
cycle, such as vapor compression, to transfer heat from a low-
temperature source to a higher-temperature sink for the purpose of 
heating potable water, and has a rated electric power input greater than 
12 kW. Such equipment includes, but is not limited to, air-source heat 
pump water heaters, water-source heat pump water heaters, and direct 
geo-exchange heat pump water heaters.
    Direct geo-exchange commercial heat pump water heater means a

representations with respect to the energy use or efficiency of the 
subject commercial water heating equipment in accordance with the 
results of testing pursuant to this appendix or the procedures in 10 CFR 
431.106 that were in place on January 1, 2016. On and after November 6, 
2017, manufacturers must make any representations with respect to energy 
use or efficiency of gas-fired and oil-fired storage water heaters and 
storage-type instantaneous water heaters in accordance with the results 
of testing pursuant to this appendix to demonstrate compliance with the 
energy conservation standards at 10 CFR 431.110.

                               1. General

    Determine the thermal efficiency and standby loss (as applicable) in 
accordance with the following sections of this appendix. Certain 
sections reference sections of Annex E.1 of ANSI Z21.10.3-2015 
(incorporated by reference; see Sec. 431.105). Where the instructions 
contained in the sections below conflict with instructions in Annex E.1 
of ANSI Z21.10.3-2015, the instructions contained in this appendix 
control.

                             2. Test Set-Up

    2.1. Placement of Water Heater. A water heater for installation on 
combustible floors must be placed on a \3/4\-inch plywood platform 
supported by three 2 x 4-inch runners. If the water heater is for 
installation on noncombustible floors, suitable noncombustible material 
must be placed on the platform. When the use of the platform for a large 
water heater is not practical, the water heater may be placed on any 
suitable flooring. A wall-mounted water heater must be mounted on a 
simulated wall section.
    2.2. Installation of Temperature Sensors. Inlet and outlet water 
piping must be turned vertically downward from the connections on the 
water heater so as to form heat traps. Temperature sensors for measuring 
supply and outlet water temperatures must be installed upstream from the 
inlet heat trap piping and downstream from the outlet heat trap piping, 
respectively, in accordance with Figure 2.1, 2.2, or 2.3 (as applicable 
based on the location of inlet and outlet piping connections) of this 
section.
    The water heater must meet the requirements shown in Figure 2.1, 
2.2, or 2.3 (as applicable) at all times during the conduct of the 
thermal efficiency and standby loss tests. Any factory-supplied heat 
traps must be installed per the installation instructions while ensuring 
the requirements in Figure 2.1, 2.2, or 2.3 are met. All dimensions 
specified in Figure 2.1, 2.2, and 2.3 and in this section are measured 
from the outer surface of the pipes and water heater outer casing (as 
applicable).

    2.3 Installation of Temperature Sensors for Measurement of Mean Tank 
Temperature. Install temperature sensors inside the tank for measurement 
of mean tank temperature according to the instructions in paragraph f of 
Annex E.1 of ANSI Z21.10.3-2015 (incorporated by reference; see Sec. 
431.105). Calculate the mean tank temperature as the average of the six 
installed temperature sensors.
    2.4. Piping Insulation. Insulate all water piping external to the 
water heater jacket, including heat traps and piping that are installed 
by the manufacturer or shipped with the unit, for at least 4 ft of 
piping length from the connection at the appliance, with material having 
an R-value not less than 4 [deg]F[middot]ft\2\[middot]h/Btu. Ensure that 
the insulation does not contact any appliance surface except at the 
location where the pipe connections penetrate the appliance jacket or 
enclosure.
    2.5. Temperature and Pressure Relief Valve Insulation. If the 
manufacturer has not provided a temperature and pressure relief valve, 
one shall be installed and insulated as specified in section 2.4 of this 
appendix.
    2.6. Vent Requirements. Follow the requirements for venting 
arrangements specified in paragraph c of Annex E.1 of ANSI Z21.10.3-2015 
(incorporated by reference; see Sec. 431.105).
    2.7. Energy Consumption. Install equipment that determines, within 
 1 percent:
    2.7.1. The quantity and rate of fuel consumed.
    2.7.2. The quantity of electricity consumed by factory-supplied 
water heater components.

                           3. Test Conditions

    3.1. Water Supply
    3.1.1. Water Supply Pressure. The pressure of the water supply must 
be maintained between 40 psi and the maximum pressure specified by the 
manufacturer of the unit being tested. The accuracy of the pressure-
measuring devices must be within  1.0 pounds per 
square inch (psi).
    3.1.2. Water Supply Temperature. During the steady-state 
verification period and the thermal efficiency test, the temperature of 
the supply water must be maintained at 70 [deg]F  
2 [deg]F.
    3.1.3. Isolate the water heater using a shutoff valve in the supply 
line with an expansion tank installed in the supply line downstream of 
the shutoff valve. There must be no shutoff means between the expansion 
tank and the appliance inlet.
    3.2. Gas Pressure for Gas-Fired Equipment. The supply gas pressure 
must be within the range specified by the manufacturer on the nameplate 
of the unit being tested. The difference between the outlet pressure of 
the gas appliance pressure regulator and the value specified by the 
manufacturer on the nameplate of the unit being tested must not exceed 
the greater of:  10 percent of the nameplate value 
or  0.2 inches water column (in. w.c.). Obtain the 
higher heating value of the gas burned.
    3.3. Ambient Room Temperature. During the soak-in period (as 
applicable), the steady-state verification period, the thermal 
efficiency test, and the standby loss test, maintain the ambient room 
temperature at 75 [deg]F  10 [deg]F at all times. 
Measure the ambient room temperature at 1-minute intervals during these 
periods, except for the soak-in period. Measure the ambient room 
temperature

[[Page 880]]

once before beginning the soak-in period, and ensure no actions are 
taken during the soak-in period that would cause the ambient room 
temperature to deviate from the allowable range. Measure the ambient 
room temperature at the vertical mid-point of the water heater and 
approximately 2 feet from the water heater jacket. Shield the sensor 
against radiation. Calculate the average ambient room temperature 
separately for the thermal efficiency test and standby loss test. During 
the thermal efficiency and standby loss tests, the ambient room 
temperature must not vary by more than  5.0 [deg]F 
at any reading from the average ambient room temperature.
    3.4. Test Air Temperature. During the steady-state verification 
period, the thermal efficiency test, and the standby loss test, the test 
air temperature must not vary by more than  5 
[deg]F from the ambient room temperature at any reading. Measure the 
test air temperature at 1-minute intervals during these periods and at a 
location within two feet of the air inlet of the water heater or the 
combustion air intake vent, as applicable. Shield the sensor against 
radiation. For units with multiple air inlets, measure the test air 
temperature at each air inlet, and maintain the specified tolerance on 
deviation from the ambient room temperature at each air inlet. For units 
without a dedicated air inlet, measure the test air temperature within 
two feet of any location on the water heater where combustion air is 
drawn.
    3.5. Maximum Air Draft. During the steady-state verification period, 
the thermal efficiency test, and the standby loss test, the water heater 
must be located in an area protected from drafts of more than 50 ft/min. 
Prior to beginning the steady-state verification period and the standby 
loss test, measure the air draft within three feet of the jacket or 
enclosure of the water heater to ensure this condition is met. Ensure 
that no other changes that would increase the air draft are made to the 
test set-up or conditions during the conduct of the tests.
    3.6. Setting the Tank Thermostat. Before starting the steady-state 
verification period (as applicable) or before the soak-in period (as 
applicable), the thermostat setting must first be obtained by starting 
with the water in the system at 70 [deg]F  2 
[deg]F. Set the thermostat to ensure:
    3.6.1. With the supply water temperature set as per section 3.1.2 of 
this appendix (i.e., 70 [deg]F  2 [deg]F), the 
water flow rate can be varied so that the outlet water temperature is 
constant at 70 [deg]F  2 [deg]F above the supply 
water temperature while the burner is firing at full firing rate; and
    3.6.2. After the water supply is turned off and the thermostat 
reduces the fuel supply to a minimum, the maximum water temperature 
measured by the topmost tank temperature sensor (i.e., the highest of 
the 6 temperature sensors used for calculating mean tank temperature, as 
required by section 2.3 of this appendix) is 140 [deg]F  5 [deg]F.
    3.7. Additional Requirements for Oil-Fired Equipment.
    3.7.1. Venting Requirements. Connect a vertical length of flue pipe 
to the flue gas outlet of sufficient height so as to meet the minimum 
draft specified by the manufacturer.
    3.7.2. Oil Supply. Adjust the burner rate so that the following 
conditions are met:
    3.7.2.1. The CO2 reading is within the range specified by 
the manufacturer;
    3.7.2.2. The fuel pump pressure is within  10 
percent of manufacturer's specifications;
    3.7.2.3. If either the fuel pump pressure or range for 
CO2 reading are not specified by the manufacturer on the 
nameplate of the unit, in literature shipped with the unit, or in 
supplemental test report instructions included with a certification 
report, then a default value of 100 psig is to be used for fuel pump 
pressure, and a default range of 9-12 percent is to be used for 
CO2 reading; and
    3.7.2.4. Smoke in the flue does not exceed No. 1 smoke as measured 
by the procedure in ASTM D2156-09 (Reapproved 2013) (incorporated by 
reference, see Sec. 431.105). To determine the smoke spot number, 
connect the smoke measuring device to an open-ended tube. This tube must 
project into the flue \1/4\ to \1/2\ of the pipe diameter.
    3.7.2.5. If no settings on the water heater have been changed and 
the water heater has not been turned off since the end of a previously 
run thermal efficiency or standby loss test, measurement of the 
CO2 reading and conduct of the smoke spot test are not 
required prior to beginning a test. Otherwise, measure the 
CO2 reading and determine the smoke spot number, with the 
burner firing, before the beginning of the steady-state verification 
period prior to the thermal efficiency test, and prior to beginning the 
standby loss test.
    3.8. Data Collection Intervals. Follow the data recording intervals 
specified in the following sections.
    3.8.1. Soak-In Period. For units that require a soak-in period, 
measure the ambient room temperature, in [deg]F, prior to beginning the 
soak-in period.
    3.8.2. Steady-State Verification Period and Thermal Efficiency Test. 
For the steady-state verification period and the thermal efficiency 
test, follow the data recording intervals specified in Table 3.1 of this 
appendix.

Notes:
\a\ These measurements are to be recorded at the start of the steady-state verification period and the end of
  the thermal efficiency test, as well as every minute during both periods.
\b\ The smoke spot test and CO2 reading are not required prior to beginning the steady-state verification period
  if no settings on the water heater have been changed and the water heater has not been turned off since the
  end of a previously-run efficiency test (i.e., thermal efficiency or standby loss).
\c\ Fuel and electricity consumption over the course of the entire thermal efficiency test must be measured and
  used in calculation of thermal efficiency.

    3.8.3. Standby Loss Test. For the standby loss test, follow the data 
recording intervals specified in Table 3.2 of this appendix. 
Additionally, the fuel and electricity consumption over the course of 
the entire test must be measured and used in calculation of standby 
loss.

Notes:
\a\ These measurements are to be recorded at the start and end of the
  test, as well as every minute during the test.
\b\ The smoke spot test and CO2 reading are not required prior to
  beginning the standby loss test if no settings on the water heater
  have been changed and the water heater has not been turned off since
  the end of a previously-run efficiency test (i.e., thermal efficiency
  or standby loss).
\c\ Mean tank temperature is calculated as the average of the 6 tank
  temperature sensors, installed per section 2.3 of this appendix.

    4. Determination of Storage Volume. Determine the storage volume by 
subtracting the tare weight, measured while the system is dry and empty, 
from the weight of the system when filled with water and dividing the 
resulting net weight of water by the density of water at the measured 
water temperature. The volume of the water contained in the water heater 
must be computed in gallons.
    5. Thermal Efficiency Test. Before beginning the steady-state 
verification period, record the applicable parameters as specified in 
section 3.8.2 of this appendix. Begin drawing water from the unit by 
opening the main supply, and adjust the water flow rate to achieve an 
outlet water temperature of 70 [deg]F  2 [deg]F 
above supply water temperature. The thermal efficiency test shall be 
deemed complete when there is a continuous, one-hour-long period where 
the steady-state conditions specified in section 5.1 of this appendix 
have been met, as confirmed by consecutive readings of the relevant 
parameters recorded at 1-minute intervals (except for fuel input rate, 
which is determined at 10-minute intervals, as specified in section 5.4 
of this appendix). During the one-hour-long period, the water heater 
must fire continuously at its full firing rate (i.e., no modulations or 
cut-outs) and no settings can be changed on the unit being tested at any 
time. The first 30

[[Page 882]]

minutes of the one-hour-period where the steady-state conditions in 
section 5.1 of this appendix are met is the steady-state verification 
period. The final 30 minutes of the one-hour-period where the steady-
state conditions in section 5.1 of this appendix are met is the thermal 
efficiency test. The last reading of the steady-state verification 
period must be the first reading of the thermal efficiency test (i.e., 
the thermal efficiency test starts immediately once the steady-state 
verification period ends).
    5.1. Steady-State Conditions. The following conditions must be met 
at consecutive readings taken at 1-minute intervals (except for fuel 
input rate, for which measurements are taken at 10-minute intervals) to 
verify the water heater has achieved steady-state operation during the 
steady-state verification period and thermal efficiency test.
    5.1.1. The water flow rate must be maintained within  0.25 gallons per minute (gpm) of the initial reading at 
the start of the steady-state verification period;
    5.1.2. Outlet water temperature must be maintained at 70 [deg]F 
 2 [deg]F above supply water temperature;
    5.1.3. Fuel input rate must be maintained within  2 percent of the rated input certified by the 
manufacturer;
    5.1.4. The supply water temperature must be maintained within  0.50 [deg]F of the initial reading at the start of the 
steady-state verification period; and
    5.1.5. The rise between the supply and outlet water temperatures 
must be maintained within  0.50 [deg]F of its 
initial value taken at the start of the steady-state verification period 
for units with rated input less than 500,000 Btu/h, and maintained 
within  1.00 [deg]F of its initial value for units 
with rated input greater than or equal to 500,000 Btu/h.
    5.2. Water Flow Measurement. Measure the total weight of water 
heated during the 30-minute thermal efficiency test with either a scale 
or a water flow meter. With either method, the error of measurement of 
weight of water heated must not exceed 1 percent of the weight of the 
total draw.
    5.3. Determination of Fuel Input Rate. During the steady-state 
verification period and the thermal efficiency test, record the fuel 
consumed at 10-minute intervals. Calculate the fuel input rate over each 
10-minute period using the equations in section 5.4 of this appendix. 
The measured fuel input rates for these 10-minute periods must not vary 
by more than  2 percent between any two readings. 
Determine the overall fuel input rate using the fuel consumption for the 
entire duration of the thermal efficiency test.
    5.4. Fuel Input Rate Calculation. To calculate the fuel input rate, 
use the following equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.014

Where,

Q = Fuel input rate, expressed in Btu/h
Qs = Total fuel flow as metered, expressed in ft\3\ for gas-

    5.5. Thermal Efficiency Calculation. Thermal efficiency must be 
calculated using data from the 30-minute thermal efficiency test. 
Calculate thermal efficiency, Et, using the following 
equation:

                          6. Standby Loss Test

    6.1. If no settings on the water heater have changed and the water 
heater has not been turned off since a previously run thermal efficiency 
or standby loss test, skip to section 6.3 of this appendix. Otherwise, 
conduct the soak-in period according to section 6.2 of this appendix.
    6.2. Soak-In Period. Conduct a soak-in period, in which the water 
heater must sit without any draws taking place for at least 12 hours. 
Begin the soak-in period after setting the tank thermostat as specified 
in section 3.6 of this appendix, and maintain these thermostat settings 
throughout the soak-in period.
    6.3. Begin the standby loss test at the first cut-out following the 
end of the soak-in period (if applicable); or at a cut-out following the 
previous thermal efficiency or standby loss test (if applicable). Allow 
the water heater to remain in standby mode. Do not change any settings 
on the water heater at any point until measurements for the standby loss 
test are finished. Begin recording the applicable parameters specified 
in section 3.8.3 of this appendix.
    6.4. At the second cut-out, record the time and ambient room 
temperature, and begin measuring the fuel and electricity consumption. 
Record the initial mean tank temperature and initial ambient room 
temperature. For the remainder of the test, continue recording the 
applicable parameters specified in section 3.8.3 of this appendix.
    6.5. Stop the test after the first cut-out that occurs after 24 
hours, or at 48 hours, whichever comes first.
    6.6. Immediately after conclusion of the standby loss test, record 
the total fuel flow and electrical energy consumption, the final ambient 
room temperature, the duration of the standby loss test, and if the test 
ends at 48 hours without a cut-out, the final mean tank temperature, or 
if the test ends after a cut-out, the maximum mean tank temperature that 
occurs after the cut-out. Calculate the average of the recorded values 
of the mean tank temperature and of the ambient room temperature taken 
at each measurement interval, including the initial and final values.
    6.7. Standby Loss Calculation. To calculate the standby loss, follow 
the steps below:
    6.7.1. The standby loss expressed as a percentage (per hour) of the 
heat content of the stored water above room temperature must be 
calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.016

Where,
[Delta]T3 = Average value of the mean tank temperature minus 
          the average value of the ambient room temperature, expressed 
          in [deg]F

    6.7.2. The standby loss expressed in Btu per hour must be calculated 
as follows:
    SL (Btu per hour) = S (% per hour) x 8.25 (Btu/gal- [deg]F) x 
Measured Volume (gal) x 70 ([deg]F).
    Where, SL refers to the standby loss of the water heater, defined as 
the amount of energy required to maintain the stored water temperature

 Sec. Appendix B to Subpart G of Part 431--Uniform Test Method for the 
   Measurement of Standby Loss of Electric Storage Water Heaters and 
                Storage-Type Instantaneous Water Heaters

    Note: Prior to November 6, 2017, manufacturers must make any 
representations with respect to the energy use or efficiency of the 
subject commercial water heating equipment in accordance with the 
results of testing pursuant to this appendix or the procedures in 10 CFR 
431.106 that were in place on January 1, 2016. On and after November 6, 
2017, manufacturers must make any representations with respect to energy 
use or efficiency of electric storage water heaters and storage-type 
instantaneous water heaters in accordance with the results of testing 
pursuant to this appendix to demonstrate compliance with the energy 
conservation standards at 10 CFR 431.110.

                               1. General

    Determine the standby loss in accordance with the following sections 
of this appendix. Certain sections reference sections of Annex E.1 of 
ANSI Z21.10.3-2015 (incorporated by reference; see Sec. 431.105). Where 
the instructions contained in the sections below conflict with 
instructions in Annex E.1 of ANSI Z21.10.3-2015, the instructions 
contained in this appendix control.

                             2. Test Set-Up

    2.1. Placement of Water Heater. A water heater for installation on 
combustible floors must be placed on a \3/4\-inch plywood platform 
supported by three 2 x 4-inch runners. If the water heater is for 
installation on noncombustible floors, suitable noncombustible material 
must be placed on the platform. When the use of the platform for a large 
water heater is not practical, the water heater may be placed on any 
suitable flooring. A wall-mounted water heater must be mounted on a 
simulated wall section.
    2.2. Installation of Temperature Sensors. Inlet and outlet piping 
must be turned vertically downward from the connections on a tank-type 
water heater so as to form heat traps. Temperature sensors for measuring 
supply water temperature must be installed upstream of the inlet heat 
trap piping, in accordance with Figure 2.1, 2.2, or 2.3 (as applicable) 
of this appendix.
    The water heater must meet the requirements shown in either Figure 
2.1, 2.2, or 2.3 (as applicable) at all times during the conduct of the 
standby loss test. Any factory-supplied heat traps must be installed per 
the installation instructions while ensuring the requirements in Figure 
2.1, 2.2, or 2.3 are met. All dimensions specified in Figure 2.1, 2.2, 
and 2.3 are measured from the outer surface of the pipes and water 
heater outer casing (as applicable).

    2.3. Installation of Temperature Sensors for Measurement of Mean 
Tank Temperature. Install temperature sensors inside the tank for 
measurement of mean tank temperature according to the instructions in 
paragraph f of Annex E.1 of ANSI Z21.10.3-2015 (incorporated by 
reference; see Sec. 431.105 rt). Calculate the mean tank temperature as 
the average of the six installed temperature sensors.
    2.4. Piping Insulation. Insulate all water piping external to the 
water heater jacket, including heat traps and piping that is installed 
by the manufacturer or shipped with the unit, for at least 4 ft of 
piping length from the connection at the appliance, with material having 
an R-value not less than 4 [deg]F[middot]ft\2\[middot]h/Btu. Ensure that 
the insulation does not contact any appliance surface except at the 
location where the pipe connections penetrate the appliance jacket or 
enclosure.
    2.5. Temperature and Pressure Relief Valve Insulation. If the 
manufacturer or has not provided a temperature and pressure relief 
valve, one shall be installed and insulated as specified in section 2.4 
of this appendix.
    2.6. Energy Consumption. Install equipment that determines, within 
 1 percent, the quantity of electricity consumed 
by factory-supplied water heater components.

                           3. Test Conditions

                            3.1. Water Supply

    3.1.1. Water Supply Pressure. The pressure of the water supply must 
be maintained between 40 psi and the maximum pressure specified by the 
manufacturer of the unit being tested. The accuracy of the pressure-
measuring devices must be within  1.0 pounds per 
square inch (psi).
    3.1.2. Water Supply Temperature. When filling the tank with water 
prior to the soak-in period, maintain the supply water temperature at 70 
[deg]F  2 [deg]F.
    3.1.3. Isolate the water heater using a shutoff valve in the supply 
line with an expansion tank installed in the supply line downstream of 
the shutoff valve. There must be no shutoff means between the expansion 
tank and the appliance inlet.
    3.2. Electrical Supply. Maintain the electrical supply voltage to 
within  5 percent of the voltage specified on the 
water heater nameplate. If a voltage range is specified on the 
nameplate, maintain the voltage to within  5 
percent of the center of the voltage range specified on the nameplate.
    3.3. Ambient Room Temperature. During the soak-in period and the 
standby loss test, maintain the ambient room temperature at 75 [deg]F 
 10 [deg]F at all times. Measure the ambient room 
temperature at 1-minute intervals during these periods, except for the 
soak-in period. Measure the ambient room temperature once before 
beginning the soak-in period, and ensure no actions are taken during the 
soak-in period that would cause the ambient room temperature to deviate 
from the allowable range. Measure the ambient room temperature at the 
vertical mid-point of the water heater and approximately 2 feet from the 
water heater jacket. Shield the sensor against radiation. Calculate the 
average ambient room temperature for the standby loss test. During the 
standby loss test, the ambient room temperature must not vary by

[[Page 887]]

more than  5.0 [deg]F at any reading from the 
average ambient room temperature.
    3.4. Maximum Air Draft. During the standby loss test, the water 
heater must be located in an area protected from drafts of more than 50 
ft/min. Prior to beginning the standby loss test, measure the air draft 
within three feet of the jacket of the water heater to ensure this 
condition is met. Ensure that no other changes that would increase the 
air draft are made to the test set-up or conditions during the conduct 
of the test.
    3.5. Setting the Tank Thermostat(s). Before starting the required 
soak-in period, the thermostat setting(s) must first be obtained as 
explained in the following sections. The thermostat setting(s) must be 
obtained by starting with the tank full of water at 70 [deg]F  2 [deg]F. After the tank is completely filled with 
water at 70 [deg]F  2 [deg]F, turn off the water 
flow, and set the thermostat(s) as follows.
    3.5.1. For water heaters with a single thermostat, the thermostat 
setting must be set so that the maximum mean tank temperature after cut-
out is 140 [deg]F  5 [deg]F.
    3.5.2. For water heaters with multiple adjustable thermostats, set 
only the topmost and bottommost thermostats, and turn off any other 
thermostats for the duration of the standby loss test. Set the topmost 
thermostat first to yield a maximum mean water temperature after cut-out 
of 140 [deg]F  5 [deg]F, as calculated using only 
the temperature readings measured at locations in the tank higher than 
the heating element corresponding to the topmost thermostat (the 
lowermost heating element corresponding to the topmost thermostat if the 
thermostat controls more than one element). While setting the topmost 
thermostat, all lower thermostats must be turned off so that no elements 
below that (those) corresponding to the topmost thermostat are in 
operation. After setting the topmost thermostat, set the bottommost 
thermostat to yield a maximum mean water temperature after cut-out of 
140 [deg]F  5 [deg]F. When setting the bottommost 
thermostat, calculate the mean tank temperature using all the 
temperature sensors installed in the tank as per section 2.3 of this 
appendix.
    3.6. Data Collection Intervals. Follow the data recording intervals 
specified in the following sections.
    3.6.1. Soak-In Period. Measure the ambient room temperature, in 
[deg]F, every minute during the soak-in period.
    3.6.2. Standby Loss Test. Follow the data recording intervals 
specified in Table 3.1 of this appendix. Additionally, the electricity 
consumption over the course of the entire test must be measured and used 
in calculation of standby loss.

 Table 3.1--Data To Be Recorded Before and During the Standby Loss Test

------------------------------------------------------------------------
Notes:
\a\ These measurements are to be recorded at the start and end of the
  test, as well as every minute during the test.
\b\ Mean tank temperature is calculated as the average of the 6 tank
  temperature sensors, installed per section 2.3 of this appendix.

    4. Determination of Storage Volume. Determine the storage volume by 
subtracting the tare weight, measured while the system is dry and empty, 
from the weight of the system when filled with water and dividing the 
resulting net weight of water by the density of water at the measured 
water temperature. The volume of water contained in the water heater 
must be computed in gallons.

                          5. Standby Loss Test

    5.1. If no settings on the water heater have changed and the water 
heater has not been turned off since a previously run standby loss test, 
skip to section 5.3 of this appendix. Otherwise, conduct the soak-in 
period according to section 5.2 of this appendix.
    5.2. Soak-In Period. Conduct a soak-in period, in which the water 
heater must sit without any draws taking place for at least 12 hours. 
Begin the soak-in period after setting the tank thermostat(s) as 
specified in section 3.5 of this appendix, and maintain these settings 
throughout the soak-in period.
    5.3. Begin the standby loss test at the first cut-out following the 
end of the soak-in period (if applicable), or at a cut-out following the 
previous standby loss test (if applicable). Allow the water heater to 
remain in standby mode. At this point, do not change any settings on the 
water heater until measurements for the standby loss test are finished. 
Begin recording applicable parameters as specified in section 3.6.2 of 
this appendix.
    5.4. At the second cut-out, record the time and ambient room 
temperature, and begin measuring the electric consumption. Record the 
initial mean tank temperature and initial ambient room temperature. For 
the remainder of the test, continue recording the applicable parameters 
specified in section 3.6.2 of this appendix.
    5.5. Stop the test after the first cut-out that occurs after 24 
hours, or at 48 hours, whichever comes first.
    5.6. Immediately after conclusion of the standby loss test, record 
the total electrical energy consumption, the final ambient room 
temperature, the duration of the standby

[[Page 888]]

loss test, and if the test ends at 48 hours without a cut-out, the final 
mean tank temperature, or if the test ends after a cut-out, the maximum 
mean tank temperature that occurs after the cut-out. Calculate the 
average of the recorded values of the mean tank temperature and of the 
ambient air temperatures taken at each measurement interval, including 
the initial and final values.
    5.7. Standby Loss Calculation. To calculate the standby loss, follow 
the steps below:
    5.7.1 The standby loss expressed as a percentage (per hour) of the 
heat content of the stored water above room temperature must be 
calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.019

Where,
[Delta]T3 = Average value of the mean tank temperature minus 
          the average value of the ambient room temperature, expressed 
          in [deg]F
[Delta]T4 = Final mean tank temperature measured at the end 
          of the test minus the initial mean tank temperature measured 
          at the start of the test, expressed in [deg]F
k = 8.25 Btu/gallon[middot] [deg]F, the nominal specific heat of water
Va = Volume of water contained in the water heater in gallons 
          measured in accordance with section 4 of this appendix
Et = Thermal efficiency = 98 percent for electric water 
          heaters with immersed heating elements
Ec = Electrical energy consumed by the water heater during 
          the duration of the test in Btu

 Sec. Appendix C to Subpart G of Part 431--Uniform Test Method for the 
Measurement of Thermal Efficiency and Standby Loss of Gas-Fired and Oil-
 Fired Instantaneous Water Heaters and Hot Water Supply Boilers (Other 
             Than Storage-Type Instantaneous Water Heaters)

    Note: Prior to November 6, 2017, manufacturers must make any 
representations with respect to the energy use or efficiency of the 
subject commercial water heating equipment in accordance with the 
results of testing pursuant to this appendix or the procedures in 10 CFR 
431.106 that were in place on January 1, 2016. On and after November 6, 
2017, manufacturers must make any representations with respect to energy 
use or efficiency of gas-fired and oil-fired instantaneous water heaters 
and hot water supply boilers (other than storage-type instantaneous 
water heaters) in accordance with the results of testing pursuant to 
this appendix to demonstrate compliance with the energy conservation 
standards at 10 CFR 431.110.

                               1. General

    Determine the thermal efficiency and standby loss (as applicable) in 
accordance with the following sections of this appendix. Certain 
sections reference sections of Annex E.1 of ANSI Z21.10.3-2015 
(incorporated by reference; see Sec. 431.105). Where the instructions 
contained in the sections below conflict with instructions in Annex E.1 
of ANSI Z21.10.3-2015, the instructions contained in this appendix 
control.

                             2. Test Set-Up

    2.1. Placement of Water Heater. A water heater for installation on 
combustible floors must be placed on a \3/4\-inch plywood platform 
supported by three 2 x 4-inch runners. If the water heater is for 
installation on noncombustible floors, suitable noncombustible material 
must be placed on the platform. When the use of the platform for a large 
water heater is not practical, the water heater may be placed on any 
suitable flooring. A wall-mounted water heater must be mounted on a 
simulated wall section.
    2.2. Test Configuration. If the instantaneous water heater or hot 
water supply boiler is not required to be tested using a recirculating 
loop, then set up the unit in accordance with Figures 2.1, 2.2, or 2.3 
of this appendix (as applicable). If the unit is required to be tested 
using a recirculating loop, then set up the unit as per Figure 2.4 of 
this appendix.

[[Page 889]]

[GRAPHIC] [TIFF OMITTED] TR10NO16.020


[[Page 890]]


[GRAPHIC] [TIFF OMITTED] TR10NO16.021

    2.2.1. If the instantaneous water heater or hot water supply boiler 
does not have any external piping, install an outlet water valve within 
10 inches of piping length of the water heater jacket or enclosure. If 
the instantaneous water heater or hot water supply boiler includes 
external piping assembled at the manufacturer's premises prior to 
shipment,

[[Page 891]]

install water valves in the outlet piping within 5 inches of the end of 
the piping supplied with the unit.
    2.2.2. If the water heater is not able to achieve an outlet water 
temperature of 70 [deg]F  2 [deg]F 
(TOWT) above the supply water temperature at full firing 
rate, a recirculating loop with pump as shown in Figure 2.4 of this 
appendix must be used.
    2.2.2.1. If a recirculating loop with a pump is used, then ensure 
that the inlet water temperature labeled as TIWT in Figure 
2.4 of this appendix, is greater than or equal to 70 [deg]F and less 
than or equal to 120 [deg]F at all times during the thermal efficiency 
test and steady-state verification period (as applicable).

                2.3. Installation of Temperature Sensors

    2.3.1. Without Recirculating Loop.
    2.3.1.1. Vertical Connections. Use Figure 2.1 (for top connections) 
and 2.2 (for bottom connections) of this appendix.
    2.3.1.2. Horizontal Connections. Use Figure 2.3 of this appendix.
    2.3.2. With Recirculating Loop. Set up the recirculating loop as 
shown in Figure 2.4 of this appendix.
    2.3.3. For water heaters with multiple outlet water connections 
leaving the water heater jacket that are required to be operated to 
achieve the rated input, temperature sensors must be installed for each 
outlet water connection leaving the water heater jacket or enclosure 
that is used during testing, in accordance with the provisions in 
sections 2.3.1 and 2.3.2 of this appendix (as applicable).
    2.4. Piping Insulation. Insulate all water piping external to the 
water heater jacket or enclosure, including piping that is installed by 
the manufacturer or shipped with the unit, for at least 4 ft of piping 
length from the connection at the appliance with material having an R-
value not less than 4 [deg]F[middot]ft\2\[middot]h/Btu. Ensure that the 
insulation does not contact any appliance surface except at the location 
where the pipe connections penetrate the appliance jacket or enclosure.
    2.5. Temperature and Pressure Relief Valve Insulation. If the 
manufacturer has not provided a temperature and pressure relief valve, 
one shall be installed and insulated as specified in section 2.4 of this 
appendix. The temperature and pressure relief valve must be installed in 
the outlet water piping, between the unit being tested and the outlet 
water valve.
    2.6. Vent Requirements. Follow the requirements for venting 
arrangements specified in paragraph c of Annex E.1 of ANSI Z21.10.3-2015 
(incorporated by reference; see Sec. 431.105).
    2.7. Energy Consumption. Install equipment that determines, within 
 1 percent:
    2.7.1. The quantity and rate of fuel consumed.
    2.7.2. The quantity of electricity consumed by factory-supplied 
water heater components, and of the test loop recirculating pump, if 
used.

                           3. Test Conditions

                            3.1. Water Supply

    3.1.1. Water Supply Pressure. The pressure of the water supply must 
be maintained between 40 psi and the maximum pressure specified by the 
manufacturer of the unit being tested. The accuracy of the pressure-
measuring devices must be within  1.0 psi.
    3.1.2. Water Supply Temperature. During the thermal efficiency test 
and steady-state verification period (as applicable), the temperature of 
the supply water (TSWT) must be maintained at 70 [deg]F 
 2 [deg]F.
    3.2. Gas Pressure for Gas-Fired Equipment. The supply gas pressure 
must be within the range specified by the manufacturer on the nameplate 
of the unit being tested. The difference between the outlet pressure of 
the gas appliance pressure regulator and the value specified by the 
manufacturer on the nameplate of the unit being tested must not exceed 
the greater of:  10 percent of the nameplate value 
or  0.2 inches water column (in. w.c.). Obtain the 
higher heating value of the gas burned.
    3.3. Ambient Room Temperature. Maintain the ambient room temperature 
at 75 [deg]F  10 [deg]F at all times during the 
steady-state verification period, the thermal efficiency test, and the 
standby loss test (as applicable). Measure the ambient room temperature 
at 1-minute intervals during these periods. Measure the ambient room 
temperature at the vertical mid-point of the water heater and 
approximately 2 feet from the water heater jacket or enclosure. Shield 
the sensor against radiation. Calculate the average ambient room 
temperature separately for the thermal efficiency test and the standby 
loss test. During the thermal efficiency and standby loss tests, the 
ambient room temperature must not vary by more than  5.0 [deg]F at any reading from the average ambient room 
temperature.
    3.4. Test Air Temperature. During the steady-state verification 
period, the thermal efficiency test, and the standby loss test (as 
applicable), the test air temperature must not vary by more than  5 [deg]F from the ambient room temperature at any 
reading. Measure the test air temperature at 1-minute intervals during 
these periods and at a location within two feet of the air inlet of the 
water heater or the combustion air intake vent, as applicable. Shield 
the sensor against radiation. For units with multiple air inlets, 
measure the test air temperature at each air inlet, and maintain the 
specified tolerance on deviation from the ambient room temperature at 
each air inlet. For units without a dedicated air inlet, measure the 
test air

[[Page 892]]

temperature within two feet of any location on the water heater where 
combustion air is drawn.
    3.5. Maximum Air Draft. During the steady-state verification period, 
the thermal efficiency test, and the standby loss test (as applicable), 
the water heater must be located in an area protected from drafts of 
more than 50 ft/min. Prior to beginning the steady-state verification 
period and the standby loss test, measure the air draft within three 
feet of the jacket or enclosure of the water heater to ensure this 
condition is met. Ensure that no other changes that would increase the 
air draft are made to the test set-up or conditions during the conduct 
of the tests.

                          3.6. Primary Control

    3.6.1. Thermostatically-Activated Water Heaters With an Internal 
Thermostat. Before starting the thermal efficiency test and the standby 
loss test (unless the thermostat is already set before the thermal 
efficiency test), the thermostat setting must be obtained. Set the 
thermostat to ensure:
    3.6.1.1. With supply water temperature set as per section 3.1.2 of 
this appendix (i.e., 70 [deg]F  2 [deg]F) the 
water flow rate can be varied so that the outlet water temperature is 
constant at 70 [deg]F  2 [deg]F above the supply 
water temperature, while the burner is firing at full firing rate; and
    3.6.1.2. After the water supply is turned off and the thermostat 
reduces the fuel supply to a minimum, the maximum heat exchanger outlet 
water temperature (TOHX) is 140 [deg]F  
5 [deg]F.
    3.6.1.3. If the water heater includes a built-in safety mechanism 
that prevents it from achieving a heat exchanger outlet water 
temperature of 140 [deg]F  5 [deg]F, adjust the 
thermostat to its maximum setting.
    3.6.2. Flow-Activated Instantaneous Water Heaters and 
Thermostatically-Activated Instantaneous Water Heaters With an External 
Thermostat. Energize the primary control such that it is always calling 
for heating and the burner is firing at the full firing rate. Maintain 
the supply water temperature as per section 3.1.2 of this appendix 
(i.e., 70 [deg]F  2 [deg]F). Set the control so 
that the outlet water temperature (TOWT) is 140 [deg]F  5 [deg]F. If the water heater includes a built-in 
safety mechanism that prevents it from achieving a heat exchanger outlet 
water temperature of 140 [deg]F  5 [deg]F, adjust 
the control to its maximum setting.

            3.7. Units With Multiple Outlet Water Connections

    3.7.1. For each connection leaving the water heater that is required 
for the unit to achieve the rated input, the outlet water temperature 
must not differ from that of any other outlet water connection by more 
than 2 [deg]F during the steady-state verification period and thermal 
efficiency test.
    3.7.2. Determine the outlet water temperature representative for the 
entire unit at every required measurement interval by calculating the 
average of the outlet water temperatures measured at each connection 
leaving the water heater jacket or enclosure that is used during 
testing. Use the outlet water temperature representative for the entire 
unit in all calculations for the thermal efficiency and standby loss 
tests, as applicable.
    3.8. Additional Requirements for Oil-Fired Equipment.
    3.8.1. Venting Requirements. Connect a vertical length of flue pipe 
to the flue gas outlet of sufficient height so as to meet the minimum 
draft specified by the manufacturer.
    3.8.2. Oil Supply. Adjust the burner rate so that the following 
conditions are met:
    3.8.2.1. The CO2 reading is within the range specified by 
the manufacturer;
    3.8.2.2. The fuel pump pressure is within  10 
percent of manufacturer's specifications;
    3.8.2.3. If either the fuel pump pressure or range for 
CO2 reading are not specified by the manufacturer on the 
nameplate of the unit, in literature shipped with the unit, or in 
supplemental test report instructions included with a certification 
report, then a default value of 100 psig is to be used for fuel pump 
pressure, and a default range of 9-12 percent is to be used for 
CO2 reading; and
    3.8.2.4. Smoke in the flue does not exceed No. 1 smoke as measured 
by the procedure in ASTM D2156-09 (Reapproved 2013) (incorporated by 
reference, see Sec. 431.105). To determine the smoke spot number, the 
smoke measuring device shall be connected to an open-ended tube. This 
tube must project into the flue \1/4\ to \1/2\ of the pipe diameter.
    3.8.2.5. If no settings on the water heater have been changed and 
the water heater has not been turned off since the end of a previously 
run thermal efficiency (or standby loss test for thermostatically-
activated instantaneous water heaters with an internal thermostat), 
measurement of the CO2 reading and conduct of the smoke spot 
test are not required prior to beginning a test. Otherwise, measure the 
CO2 reading and determine the smoke spot number, with the 
burner firing, before beginning measurements for the steady-state 
verification period (prior to beginning the thermal efficiency test or 
standby loss test, as applicable). However, measurement of the 
CO2 reading and conduct of the smoke spot test are not 
required for the standby loss test for thermostatically-activated 
instantaneous water heaters with an external thermostat and flow-
activated instantaneous water heaters.
    3.9. Data Collection Intervals. Follow the data recording intervals 
specified in the following sections.

[[Page 893]]

    3.9.1. Steady-State Verification Period and Thermal Efficiency Test. 
For the steady-state verification period and the thermal efficiency 
test, follow the data recording intervals specified in Table 3.1 of this 
appendix. These data recording intervals must also be followed if 
conducting a steady-state verification period prior to conducting the 
standby loss test.

Notes:
\a\ These measurements are to be recorded at the start and end of both the steady-state verification period and
  the thermal efficiency test, as well as every minute during both periods.
\b\ The smoke spot test and CO2 reading are not required prior to beginning the steady-state verification period
  if no settings on the water heater have been changed and the water heater has not been turned off since the
  end of a previously-run efficiency test (i.e., thermal efficiency or standby loss).
\c\ Fuel and electricity consumption over the course of the entire thermal efficiency test must be measured and
  used in calculation of thermal efficiency.
\d\ Only measured when a recirculating loop is used.

    3.9.2. Standby Loss Test. For the standby loss test, follow the data 
recording intervals specified in Table 3.2 of this appendix. (Follow the 
data recording intervals specified in Table 3.1 of this appendix of the 
steady-state verification period, if conducted prior to the standby loss 
test.) Additionally, the fuel and electricity consumption over the 
course of the entire test must be measured and used in calculation of 
standby loss.

Notes:
\a\ These measurements are to be recorded at the start and end of the
  test, as well as every minute during the test.
\b\ The water flow rate and supply water temperature and inlet water
  temperature (if a recirculating loop is used) must be measured during
  the steady-state verification period at 1-minute intervals. After the
  steady-state verification period ends, flow rate, supply water
  temperature, and inlet water temperature (if measured) are not
  required to be measured during the standby loss test, as there is no
  flow occurring during the standby loss test.

    4. Determination of Storage Volume. Determine the storage volume by 
subtracting the tare weight, measured while the system is dry and empty, 
from the weight of the system when filled with water and dividing the 
resulting net weight of water by the density

[[Page 894]]

of water at the measured water temperature. The volume of water 
contained in the water heater must be computed in gallons.

                           5. Fuel Input Rate

    5.1. Determination of Fuel Input Rate. During the steady-state 
verification period and thermal efficiency test, as applicable, record 
the fuel consumption at 10-minute intervals. Calculate the fuel input 
rate for each 10-minute period using the equations in section 5.2 of 
this appendix. The measured fuel input rates for these 10-minute periods 
must not vary by more than  2 percent between any 
two readings. Determine the overall fuel input rate using the fuel 
consumption for the entire duration of the thermal efficiency test.
    5.2. Fuel Input Rate Calculation. To calculate the fuel input rate, 
use the following equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.022

Where:

Q = Fuel input rate, expressed in Btu/h
Qs = Total fuel flow as metered, expressed in ft\3\ for gas-
          fired equipment and lb for oil-fired equipment
Cs = Correction applied to the heating value of a gas H, when 
          it is metered at temperature and/or pressure conditions other 
          than the standard conditions for which the value of H is 
          based. Cs=1 for oil-fired equipment.
H = Higher heating value of the fuel, expressed as Btu/ft\3\ for gas-
          fired equipment and Btu/lb for oil-fired equipment.
t = Duration of measurement of fuel consumption

    6. Thermal Efficiency Test. Before beginning the steady-state 
verification period, record the applicable parameters as specified in 
section 3.9.1 of this appendix. Begin drawing water from the unit by 
opening the main supply and outlet water valve, and adjust the water 
flow rate to achieve an outlet water temperature of 70 [deg]F  2 [deg]F above supply water temperature. The thermal 
efficiency test shall be deemed complete when there is a continuous, 
one-hour-long period where the steady-state conditions specified in 
section 6.1 of this appendix have been met, as confirmed by consecutive 
readings of the relevant parameters at 1-minute intervals (except for 
fuel input rate, which is determined at 10-minute intervals, as 
specified in section 5.1 of this appendix). During the one-hour-long 
period, the water heater must fire continuously at its full firing rate 
(i.e., no modulation or cut-outs) and no settings can be changed on the 
unit being tested at any time. The first 30 minutes of the one-hour-
period where the steady-state conditions in section 6.1 of this appendix 
are met is the steady-state verification period. The final 30 minutes of 
the one-hour-period where the steady-state conditions in section 6.1 of 
this appendix are met is the thermal efficiency test. The last reading 
of the steady-state verification period must be the first reading of the 
thermal efficiency test (i.e., the thermal efficiency test starts 
immediately once the steady-state verification period ends).
    6.1. Steady-State Conditions. The following conditions must be met 
at consecutive readings taken at 1-minute intervals (except for fuel 
input rate, for which measurements are taken at 10-minute intervals) to 
verify the water heater has achieved steady-state operation during the 
steady-state verification period and the thermal efficiency test.
    6.1.1. The water flow rate must be maintained within  0.25 gallons per minute (gpm) of the initial reading at 
the start of the steady-state verification period.
    6.1.2. Outlet water temperature must be maintained at 70 [deg]F 
 2 [deg]F above supply water temperature.
    6.1.3. Fuel input rate must be maintained within  2 percent of the rated input certified by the 
manufacturer.
    6.1.4. The supply water temperature (TSWT) (or inlet 
water temperature (TIWT) if a recirculating loop is used) 
must be maintained within  0.50 [deg]F of the 
initial reading at the start of the steady-state verification period.
    6.1.5. The rise between supply (or inlet if a recirculating loop is 
used) and outlet water temperatures must be maintained within  0.50 [deg]F of its initial value taken at the start of 
the steady-state verification period for units with rated input less 
than 500,000 Btu/h, and maintained within  1.00 
[deg]F of its initial value for units with rated input greater than or 
equal to 500,000 Btu/h.
    6.2. Water Flow Measurement. Measure the total weight of water 
heated during the 30-minute thermal efficiency test with either a scale 
or a water flow meter. With either method, the error of measurement of 
weight of water heated must not exceed 1 percent of the weight of the 
total draw.
    6.3. Thermal Efficiency Calculation. Thermal efficiency must be 
calculated using data from the 30-minute thermal efficiency test.

[[Page 895]]

Calculate thermal efficiency, Et, using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.023

Cs = Correction applied to the heating value of a gas H, when 
          it is metered at temperature and/or pressure conditions other 
          than the standard conditions for which the value of H is 
          based. Cs=1 for oil-fired equipment.
H = Higher heating value of the fuel, expressed in Btu/ft\3\ (gas) or 
          Btu/lb (oil)
Ec = Electrical consumption of the water heater and, when 
          used, the test set-up recirculating pump, expressed in Btu

    7. Standby Loss Test. If the standby loss test is conducted 
immediately after a thermal efficiency test and no settings or 
conditions have been changed since the completion of the thermal 
efficiency test, then skip to section 7.2 or 7.3 of this appendix (as 
applicable). Otherwise, perform the steady-state verification in section 
7.1 of this appendix. For thermostatically-activated instantaneous water 
heaters with an internal thermostat, use section 7.2 of this appendix to 
conduct the standby loss test, and for flow-activated and/or 
thermostatically-activated instantaneous water heaters with an external 
thermostat use section 7.3 of this appendix to conduct the standby loss 
test.
    7.1. Steady-State Verification Period. For water heaters where the 
standby loss test is not conducted immediately following the thermal 
efficiency test, the steady-state verification period must be conducted 
before starting the standby loss test. Set the primary control in 
accordance with section 3.6 of this appendix, such that the primary 
control is always calling for heat and the water heater is firing 
continuously at the full firing rate (i.e., no modulation or cut-outs). 
Begin drawing water from the unit by opening the main supply and the 
outlet water valve, and adjust the water flow rate to achieve an outlet 
water temperature of 70 [deg]F  2 [deg]F above 
supply water temperature. The steady-state verification period is 
complete when there is a continuous 30-minute period where the steady-
state conditions specified in section 7.1.1 of this appendix are met, as 
confirmed by consecutive readings of the relevant parameters recorded at 
1-minute intervals (except for fuel input rate, which is determined at 
10-minute intervals, as specified in section 5.1 of this appendix).
    7.1.1. Steady-State Conditions. The following conditions must be met 
at consecutive readings taken at 1-minute intervals (except for fuel 
input rate, for which measurements are taken at 10-minute intervals) to 
verify the water heater has achieved steady-state operation during the 
steady-state verification period prior to conducting the standby loss 
test.
    7.1.1.1. The water flow rate must be maintained within  0.25 gallons per minute (gpm) of the initial reading at 
the start of the steady-state verification period;
    7.1.1.2. Fuel input rate must be maintained within  2 percent of the rated input certified by the 
manufacturer;
    7.1.1.3. The supply water temperature (TSWT) (or inlet 
water temperature (TIWT) if a recirculating loop is used) 
must be maintained within  0.50 [deg]F of the 
initial reading at the start of the steady-state verification period; 
and
    7.1.1.4. The rise between the supply (or inlet if a recirculating 
loop is used) and outlet water temperatures must be maintained within 
 0.50 [deg]F of its initial value taken at the 
start of the steady-state verification period for units with rated input 
less than 500,000 Btu/h, and maintained within  
1.00 [deg]F of its initial value for units with rated input greater than 
or equal to 500,000 Btu/h.
    7.2. Thermostatically-Activated Instantaneous Water Heaters with an 
Internal Thermostat. For water heaters that will experience cut-in based 
on a temperature-activated control that is internal to the water heater, 
use the following steps to conduct the standby loss test.
    7.2.1. Immediately after the thermal efficiency test or the steady-
state verification period (as applicable), turn off the outlet water 
valve(s) (installed as per the provisions in section 2.2 of this 
appendix), and the water pump (if applicable) simultaneously and ensure 
that there is no flow of water through the water heater.
    7.2.2. After the first cut-out following the end of the thermal 
efficiency test or steady-state verification period (as applicable),

[[Page 896]]

allow the water heater to remain in standby mode. Do not change any 
settings on the water heater at any point until measurements for the 
standby loss test are finished. Begin recording the applicable 
parameters specified in section 3.9.2 of this appendix.
    7.2.3. At the second cut-out, record the time and ambient room 
temperature, and begin measuring the fuel and electricity consumption. 
Record the initial heat exchanger outlet water temperature 
(TOHX) and initial ambient room temperature. For the 
remainder of the test, continue recording the applicable parameters 
specified in section 3.9.2 of this appendix.
    7.2.4. Stop the test after the first cut-out that occurs after 24 
hours, or at 48 hours, whichever comes first.
    7.2.5. Immediately after conclusion of the standby loss test, record 
the total fuel flow and electrical energy consumption, the final ambient 
room temperature, the duration of the standby loss test, and if the test 
ends at 48 hours without a cut-out, the final heat exchanger outlet 
temperature, or if the test ends after a cut-out, the maximum heat 
exchanger outlet temperature that occurs after the cut-out. Calculate 
the average of the recorded values of the heat exchanger outlet water 
temperature and the ambient room temperature taken at each measurement 
interval, including the initial and final values.
    7.2.6. Standby Loss Calculation. To calculate the standby loss, 
follow the steps below:
    7.2.6.1. The standby loss expressed as a percentage (per hour) of 
the heat content of the stored water above room temperature must be 
calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.024

Where:

[Delta]T3 = Average value of the heat exchanger outlet water 
          temperature (TOHX) minus the average value of the 
          ambient room temperature, expressed in [deg]F
[Delta]T4 = Final heat exchanger outlet water temperature 
          (TOHX) measured at the end of the test minus the 
          initial heat exchanger outlet water temperature 
          (TOHX) measured at the start of the test, expressed 
          in [deg]F

          based. Cs=1 for oil-fired equipment.
Qs = Total fuel flow as metered, expressed in ft\3\ (gas) or 
          lb (oil)

          Btu/lb (oil)
S = Standby loss, the average hourly energy required to maintain the 
          stored water temperature expressed as a percentage of the 
          initial heat content of the stored water above room 
          temperature

    7.2.6.2. The standby loss expressed in Btu per hour must be 
calculated as follows:
    SL (Btu per hour) = S (% per hour) x 8.25 (Btu/gal- [deg]F) x 
Measured Volume (gal) x 70 ([deg]F).
    Where, SL refers to the standby loss of the water heater, defined as 
the amount of energy required to maintain the stored water temperature 
expressed in Btu per hour.
    7.3. Flow-Activated and Thermostatically-Activated Instantaneous 
Water Heaters with an External Thermostat. For water heaters that are 
either flow-activated or thermostatically-activated with an external 
thermostat, use the following steps to conduct the standby loss test.
    7.3.1. Immediately after the thermal efficiency test or the steady-
state verification period (as applicable), de-energize the primary 
control to end the call for heating. If the main burners do not cut out, 
then turn off the fuel supply.
    7.3.1.1. If the unit does not have an integral pump purge 
functionality, then turn off the outlet water valve and water pump at 
this time.
    7.3.1.2. If the unit has an integral pump purge functionality, allow 
the pump purge operation to continue. After the pump purge operation is 
complete, immediately turn off the outlet water valve and water pump and 
continue recording the required parameters for the remainder of the 
test.

[[Page 897]]

                          7.3.2. Recording Data

    7.3.2.1. For units with pump purge functionality, record the initial 
heat exchanger outlet water temperature (TOHX), and ambient 
room temperature when the main burner(s) cut-out or the fuel supply is 
turned off. After the pump purge operation is complete, record the time 
as t = 0 and the initial electricity meter reading. Continue to monitor 
and record the heat exchanger outlet water temperature (TOHX) 
and time elapsed from the start of the test, and the electricity 
consumption as per the requirements in section 3.9.2 of this appendix.
    7.3.2.2. For units not equipped with pump purge functionality, begin 
recording the measurements as per the requirements of section 3.9.2 of 
this appendix when the main burner(s) cut-out or the fuel supply is 
turned off. Specifically, record the time as t = 0, and record the 
initial heat exchanger outlet water temperature (TOHX), 
ambient room temperature, and electricity meter readings. Continue to 
monitor and record the heat exchanger outlet water temperature 
(TOHX) and the time elapsed from the start of the test as per 
the requirements in section 3.9.2 of this appendix.
    7.3.3. Stopping Criteria. Stop the test when one of the following 
occurs:
    7.3.3.1. The heat exchanger outlet water temperature 
(TOHX) decreases by 35 [deg]F from its value recorded 
immediately after the main burner(s) has cut-out, and the pump purge 
operation (if applicable) is complete; or
    7.3.3.2. 24 hours have elapsed from the start of the test.
    7.3.4. At the end of the test, record the final heat exchanger 
outlet water temperature (TOHX), fuel consumed, electricity 
consumed from time t=0, and the time elapsed from the start of the test.

                     7.3.5. Standby Loss Calculation

    7.3.5.1. Once the test is complete, use the following equation to 
calculate the standby loss as a percentage (per hour) of the heat 
content of the stored water above room temperature:

[GRAPHIC] [TIFF OMITTED] TR10NO16.025

Where,
[Delta]T1 = Heat exchanger outlet water temperature 
          (TOHX) measured after the pump purge operation is 
          complete (if the unit is integrated with pump purge 
          functionality); or after the main burner(s) cut-out (if the 
          unit is not equipped with pump purge functionality) minus heat 
          exchanger outlet water temperature (TOHX) measured 
          at the end of the test, expressed in [deg]F
[Delta]T2 = Heat exchanger outlet water temperature 
          (TOHX) minus the ambient temperature, both measured 
          after the main burner(s) cut-out, at the start of the test,

Va = Volume of water contained in the water heater in gallons 
          measured in accordance with section 4 of this appendix
Et = Thermal efficiency of the water heater determined in 
          accordance with section 6 of this appendix, expressed in %
Ec = Electrical energy consumed by the water heater during 
          the duration of the test in Btu
t = Total duration of the test in hours

          stored water temperature expressed as a percentage of the 
          initial heat content of the stored water above room 
          temperature

    7.3.5.2. The standby loss expressed in terms of Btu per hour must be 
calculated as follows:
    SL (Btu per hour) = S (% per hour) x 8.25 (Btu/gal- [deg]F) x 
Measured Volume (gal) x 70 ([deg]F)
    Where, SL refers to the standby loss of the water heater, defined as 
the amount of energy required to maintain the stored water temperature 
expressed in Btu per hour.

 Sec. Appendix D to Subpart G of Part 431--Uniform Test Method for the 
  Measurement of Standby Loss of Electric Instantaneous Water Heaters 
          (Other Than Storage-Type Instantaneous Water Heaters)

    Note: Prior to November 6, 2017, manufacturers must make any 
representations with respect to the energy use or efficiency of the 
subject commercial water heating equipment in accordance with the 
results of testing pursuant to this appendix or the procedures in 10 CFR 
431.106 that were in place on January

[[Page 898]]

1, 2016. On and after November 6, 2017, manufacturers must make any 
representations with respect to energy use or efficiency of electric 
instantaneous water heaters (other than storage-type instantaneous water 
heaters) in accordance with the results of testing pursuant to this 
appendix to demonstrate compliance with the energy conservation 
standards at 10 CFR 431.110.

                               1. General

    Determine the standby loss (as applicable) in accordance with the 
following sections of this appendix.

                             2. Test Set-Up

    2.1. Placement of Water Heater. A water heater for installation on 
combustible floors must be placed on a \3/4\-inch plywood platform 
supported by three 2 x 4-inch runners. If the water heater is for 
installation on noncombustible floors, suitable noncombustible material 
must be placed on the platform. When the use of the platform for a large 
water heater is not practical, the water heater may be placed on any 
suitable flooring. A wall-mounted water heater must be mounted on a 
simulated wall section.
    2.2. Test Configuration. If the instantaneous water heater is not 
required to be tested using a recirculating loop, then set up the unit 
in accordance with Figure 2.1, 2.2, or 2.3 of this appendix (as 
applicable). If the unit is required to be tested using a recirculating 
loop, then set up the unit as per Figure 2.4 of this appendix.

[[Page 899]]

[GRAPHIC] [TIFF OMITTED] TR10NO16.026


[[Page 900]]


[GRAPHIC] [TIFF OMITTED] TR10NO16.027

    2.2.1. If the instantaneous water heater does not have any external 
piping, install an outlet water valve within 10 inches of the piping 
length of the water heater jacket or enclosure. If the instantaneous 
water heater includes external piping assembled at the manufacturer's 
premises prior to shipment, install water valves in the outlet piping 
within 5 inches of the end of the piping supplied with the unit.

[[Page 901]]

    2.2.2. If the water heater is not able to achieve an outlet water 
temperature of 70 [deg]F  2 [deg]F above the 
supply water temperature at a constant maximum electricity input rate, a 
recirculating loop with pump as shown in Figure 2.4 of this appendix 
must be used.
    2.2.2.1. If a recirculating loop with a pump is used, then ensure 
that the inlet water temperature (labeled as TIWT in Figure 
2.4 of this appendix) is greater than or equal to 70 [deg]F and less 
than or equal to 120 [deg]F at all times during the steady-state 
verification period.

                2.3. Installation of Temperature Sensors

                    2.3.1. Without Recirculating Loop

    2.3.1.1. Vertical Connections. Use Figure 2.1 (for top connections) 
and 2.2 (for bottom connections) of this appendix.
    2.3.1.2. Horizontal Connections. Use Figure 2.3 of this appendix.
    2.3.2. With Recirculating Loop. Set up the recirculating loop as 
shown in Figure 2.4 of this appendix.
    2.3.3. For water heaters with multiple outlet water connections 
leaving the water heater jacket that are required to be operated to 
achieve the rated input, temperature sensors must be installed for each 
outlet water connection leaving the water heater jacket or enclosure 
that is used during testing, in accordance with sections 2.3.1 and 2.3.2 
of this appendix.
    2.4. Piping Insulation. Insulate all the water piping external to 
the water heater jacket or enclosure, including piping that is installed 
by the manufacturer or shipped with the unit, for at least 4 ft of 
piping length from the connection at the appliance with material having 
an R-value not less than 4 [deg]F[middot]f \t2\[middot]h/Btu. Ensure 
that the insulation does not contact any appliance surface except at the 
location where the pipe connections penetrate the appliance jacket or 
enclosure.
    2.5. Temperature and Pressure Relief Valve Insulation. If the 
manufacturer has not provided a temperature and pressure relief valve, 
one shall be installed and insulated as specified in section 2.4 of this 
appendix. The temperature and pressure relief valve must be installed in 
the outlet water piping between the unit being tested and the outlet 
water valve.
    2.6. Energy Consumption. Install equipment that determines, within 
 1 percent, the quantity of electricity consumed 
by factory-supplied water heater components, and of the test loop 
recirculating pump, if used.

                           3. Test Conditions

                            3.1. Water Supply

    3.1.1. Water Supply Pressure. The pressure of the water supply must 
be maintained between 40 psi and the maximum pressure specified by the 
manufacturer of the unit being tested. The accuracy of the pressure-
measuring devices must be  1.0 psi.
    3.1.2. Water Supply Temperature. During the steady-state 
verification period, the temperature of the supply water 
(TSWT) must be maintained at 70 [deg]F  
2 [deg]F.
    .2. Electrical Supply. Maintain the electrical supply voltage to 
within  5 percent of the voltage specified on the 
water heater nameplate. If a voltage range is specified on the 
nameplate, maintain the voltage to within  5 
percent of the center of the voltage range specified on the nameplate.
    3.3. Ambient Room Temperature. Maintain the ambient room temperature 
at 75 [deg]F  10 [deg]F at all times during the 
steady-state verification period and the standby loss test. Measure the 
ambient room temperature at 1-minute intervals during these periods. 
Measure the ambient room temperature at the vertical mid-point of the 
water heater and approximately 2 feet from the water heater jacket or 
enclosure. Shield the sensor against radiation. Calculate the average 
ambient room temperature for the standby loss test. During the standby 
loss test, the ambient room temperature must not vary more than  5.0 [deg]F at any reading from the average ambient room 
temperature.
    3.4. Maximum Air Draft. During the steady-state verification period 
and the standby loss test, the water heater must be located in an area 
protected from drafts of more than 50 ft/min. Prior to beginning steady-
state verification before the standby loss test, measure the air draft 
within three feet of the jacket or enclosure of the water heater to 
ensure this condition is met. Ensure that no other changes that would 
increase the air draft are made to the test set-up or conditions during 
the conduct of the test.

                          3.5. Primary Control

    3.5.1. Thermostatically-Activated Water Heaters with an Internal 
Thermostat. Before starting the steady-state verification prior to the 
standby loss test, the thermostat setting must be obtained. Set the 
thermostat to ensure:
    3.5.1.1. With supply water temperature as per section 3.1.2 of this 
appendix (i.e., 70 [deg]F  2 [deg]F) the water 
flow rate can be varied so that the outlet water temperature is constant 
at 70 [deg]F  2 [deg]F above the supply water 
temperature, while the heating element is operating at the rated input.
    3.5.1.2. After the water supply is turned off and the thermostat 
reduces the electricity supply to the heating element to a minimum, the 
maximum heat exchanger outlet water temperature (TOHX) is 140 
[deg]F  5 [deg]F.
    3.5.1.3. If the water heater includes a built-in safety mechanism 
that prevents it from achieving a heat exchanger outlet water 
temperature of 140 [deg]F  5 [deg]F, adjust the 
thermostat to its maximum setting.

    3.5.2. Flow-Activated Instantaneous Water Heaters and 
Thermostatically-Activated Instantaneous Water Heaters with an External 
Thermostat. Before starting the steady-state verification prior to the 
standby loss test energize the primary control such that it is always 
calling for heating and the heating element is operating at the rated 
input. Maintain the supply water temperature as per section 3.1.2 of 
this appendix (i.e., 70 [deg]F  2 [deg]F). Set the 
control so that the outlet water temperature (TOWT) is 140 
[deg]F  5 [deg]F. If the water heater includes a 
built-in safety mechanism that prevents it from achieving a heat 
exchanger outlet water temperature of 140 [deg]F  
5 [deg]F, adjust the control to its maximum setting.

          3.6. For Units With Multiple Outlet Water Connections

    3.6.1. For each connection leaving the water heater that is required 
for the unit to achieve the rated input, the outlet water temperature 
must not differ from that of any other outlet water connection by more 
than 2 [deg]F during the steady-state verification period prior to the 
standby loss test.
    3.6.2. Determine the outlet water temperature representative for the 
entire unit at every required measurement interval by calculating the 
average of the outlet water temperatures measured at each connection 
leaving the water heater jacket or enclosure that is used during 
testing. Use the outlet water temperature representative for the entire 
unit in all calculations for the standby loss test.
    3.7. Data Collection Intervals. During the standby loss test, follow 
the data recording intervals specified in Table 3.1 of this appendix. 
Also, the electricity consumption over the course of the entire test 
must be measured and used in calculation of standby loss.
    3.7.1. Steady-State Verification Period. Follow the data recording 
intervals specified in Table 3.1 of this appendix.

  test, as well as every minute during the test.

    4. Determination of Storage Volume. Determine the storage volume by 
subtracting the tare weight--measured while the system is dry and 
empty--from the weight of the system when filled with water and dividing 
the resulting net weight of water by the density of water at the 
measured water temperature. The volume of water contained in the water 
heater must be computed in gallons.
    5. Standby Loss Test. Perform the steady-state verification period 
in accordance with section 5.1 of this appendix. For thermostatically-
activated instantaneous water heaters with an internal thermostat, use 
section 5.2 of this appendix to conduct the standby loss test, and for 
flow-activated and/or thermostatically-activated instantaneous water 
heaters with an external thermostat (including remote thermostatically 
activated and/or flow-activated instantaneous water heaters), use 
section 5.3 of this appendix to conduct the standby loss test.
    Set the primary control in accordance with section 3.5 of this 
appendix, such that the

[[Page 903]]

primary control is always calling for heat and the water heater is 
operating at its full rated input. Begin drawing water from the unit by 
opening the main supply and the outlet water valve, and adjust the water 
flow rate to achieve an outlet water temperature of 70 [deg]F  2 [deg]F above supply water temperature. At this time, 
begin recording the parameters specified in section 3.7.1 of this 
appendix. The steady-state verification period is complete when there is 
a continuous 30-minute period where the steady-state conditions 
specified in section 5.1 of this appendix are met, as confirmed by 
consecutive readings of the relevant parameters recorded at 1-minute 
intervals (except for electric power input rate, which is determined at 
10-minute intervals, as specified in section 3.7.1 of this appendix).
    5.1. Steady-State Conditions. The following conditions must be met 
at consecutive readings taken at 1-minute intervals (except for 
electricity input rate, for which measurements are taken at 10-minute 
intervals) to verify the water heater has achieved steady-state 
operation prior to conducting the standby loss test.
    5.1.1. The water flow rate must be maintained within  0.25 gallons per minute (gpm) of the initial reading at 
the start of the steady-state verification period;
    5.1.2. Electric power input rate must be maintained within 2 percent 
of the rated input certified by the manufacturer.
    5.1.3. The supply water temperature (or inlet water temperature if a 
recirculating loop is used) must be maintained within  0.50 [deg]F of the initial reading at the start of the 
steady-state verification period; and
    5.1.4. The rise between the supply (or inlet if a recirculating loop 
is used) and outlet water temperatures is maintained within  0.50 [deg]F of its initial value taken at the start of 
the steady-state verification period for units with rated input less 
than 500,000 Btu/h, and maintained within  1.00 
[deg]F of its initial value for units with rated input greater than or 
equal to 500,000 Btu/h.
    5.2. Thermostatically-Activated Instantaneous Water Heaters with an 
Internal Thermostat. For water heaters that will experience cut-in based 
on a temperature-activated control that is internal to the water heater, 
use the following steps to conduct the standby loss test.
    5.2.1. Immediately after the steady-state verification period, turn 
off the outlet water valve(s) (installed as per the provisions in 
section 2.2 of this appendix), and the water pump (if applicable) 
simultaneously and ensure that there is no flow of water through the 
water heater.
    5.2.2. After the first cut-out following the steady-state 
verification period, allow the water heater to remain in standby mode. 
Do not change any settings on the water heater at any point until 
measurements for the standby loss test are finished. Begin recording the 
applicable parameters specified in section 3.7.2 of this appendix.
    5.2.3. At the second cut-out, record the time and ambient room 
temperature, and begin measuring the electricity consumption. Record the 
initial heat exchanger outlet water temperature (TOHX) and 
initial ambient room temperature. For the remainder of the test, 
continue recording the applicable parameters specified in section 3.7.2 
of this appendix.
    5.2.4. Stop the test after the first cut-out that occurs after 24 
hours, or at 48 hours, whichever comes first.
    5.2.5. Immediately after conclusion of the standby loss test, record 
the total electrical energy consumption, the final ambient room 
temperature, the duration of the standby loss test, and if the test ends 
at 48 hours without a cut-out, the final heat exchanger outlet 
temperature, or if the test ends after a cut-out, the maximum heat 
exchanger outlet temperature that occurs after the cut-out. Calculate 
the average of the recorded values of the heat exchanger outlet water 
temperature and of the ambient air temperatures taken at each 
measurement interval, including the initial and final values.
    5.2.6. Standby Loss Calculation. Calculate the standby loss, 
expressed as a percentage (per hour) of the heat content of the stored 
water above room temperature, using the following equation:
[GRAPHIC] [TIFF OMITTED] TR10NO16.028

Where,

[Delta]T3 = Average value of the heat exchanger outlet water 
          temperature (TOHX) minus the average value of the 
          ambient room temperature, expressed in [deg]F
[Delta]T4 = Final heat exchanger outlet water temperature 
          (TOHX) measured at the end of the test minus the 
          initial heat exchanger outlet water temperature 
          (TOHX)

          stored water temperature expressed as a percentage of the 
          initial heat content of the stored water above room 
          temperature

    5.3. Flow-Activated and Thermostatically-Activated Instantaneous 
Water Heaters with an External Thermostat. For water heaters that are 
either flow-activated or thermostatically-activated with an external 
thermostat, use the following steps to conduct the standby loss test:
    5.3.1. Immediately after the steady-state verification period, de-
energize the primary control to end the call for heating. If the heating 
elements do not cut out, then turn off the electricity supply to the 
heating elements. After the heating elements have cut-out, or the 
electricity supply to the heating elements is turned off, begin 
recording the measurements as per the requirements in section 3.7.2 of 
this appendix.
    5.3.1.1. If the unit does not have an integral pump purge 
functionality, then turn off the outlet water valve and water pump 
immediately after the main burners cut-out.
    5.3.1.2. If the unit has an integral pump purge functionality, allow 
the pump purge operation to continue. After the pump purge operation is 
complete, immediately turn off the outlet water valve and water pump and 
continue recording the required parameters for the remainder of the 
test.

                          5.3.2. Recording Data

    5.3.2.1. For units with pump purge functionality, record the initial 
heat exchanger outlet water temperature (TOHX), and ambient 
room temperature when the main heating element(s) cut-out or the 
electricity supply to the heating element(s) is turned off. After the 
pump purge operation is complete, record the time as t = 0 and the 
initial electricity meter reading. Continue to monitor and record the 
heat exchanger outlet water temperature (TOHX) and time 
elapsed from the start of the test as per the requirements in section 
3.7.2 of this appendix.
    5.3.2.2. For units not equipped with pump purge functionality, begin 
recording the measurements as per the requirements of section 3.7.2 of 
this appendix when the main heating element(s) cut-out or the 
electricity supply to the heating element(s) is turned off. 
Specifically, record the time as t = 0, and record the initial heat 
exchanger outlet water temperature (TOHX), ambient room 
temperature, and electricity meter readings. Continue to monitor and 
record the heat exchanger outlet water temperature (TOHX) and 
the time elapsed from the start of the test as per the requirements in 
section 3.7.2 of this appendix.
    5.3.3. Stopping Criteria. Stop the test when one of the following 
occurs:
    5.3.3.1. The heat exchanger outlet water temperature 
(TOHX) decreases by 35 [deg]F from its value recorded after 
the main heating element(s) have cut-out, and the pump purge operation 
(if applicable) is complete; or
    5.3.3.2. 24 hours have elapsed from the start of the test.
    5.3.4. At the end of the test, record the final heat exchanger 
outlet water temperature (TOHX), electricity consumed from 
time t = 0, and the time elapsed from the start of the test.
    5.3.5. Standby Loss Calculation. Calculate the standby loss, 
expressed as a percentage (per hour) of the heat content of the stored 
water above room temperature, using the following equation:

Where,

[Delta]T1 = Heat exchanger outlet water temperature 
          (TOHX) measured after the pump purge operation is 
          complete (if the unit is integrated with pump purge 
          functionality); or after the main heating element(s) cut-out 
          (if the unit is not equipped with pump purge functionality) 
          minus heat exchanger outlet water temperature

                Subpart H_Automatic Commercial Ice Makers

    Source: 70 FR 60415, Oct. 18, 2005, unless otherwise noted.



Sec. 431.131  Purpose and scope.

    This subpart contains energy conservation requirements for 
commercial ice makers, pursuant to Part C of Title III of the Energy 
Policy and Conservation Act, as amended, 42 U.S.C. 6311-6317.



Sec. 431.132  Definitions concerning automatic commercial ice makers.

    Automatic commercial ice maker means a factory-made assembly (not 
necessarily shipped in 1 package) that--
    (1) Consists of a condensing unit and ice-making section operating 
as an integrated unit, with means for making and harvesting ice; and
    (2) May include means for storing ice, dispensing ice, or storing 
and dispensing ice.
    Basic model means all units of a given type of covered product (or 
class thereof) manufactured by one manufacturer, having the same primary 
energy source, and which have essentially identical electrical, 
physical, and functional (or hydraulic) characteristics that affect 
energy consumption, energy efficiency, water consumption, or water 
efficiency.
    Batch type ice maker means an ice maker having alternate freezing 
and harvesting periods. This includes automatic commercial ice makers 
that produce cube type ice and other batch technologies. Referred to as 
cubes type ice maker in AHRI 810 (incorporated by reference, see Sec. 
431.133).
    Continuous type ice maker means an ice maker that continually 
freezes and harvests ice at the same time.
    Cube type ice means ice that is fairly uniform, hard, solid, usually 
clear, and generally weighs less than two ounces (60 grams) per piece, 
as distinguished from flake, crushed, or fragmented ice. Note that this 
conflicts and takes precedence over the definition established in AHRI 
810 (incorporated by reference, see Sec. 431.133), which indicates that 
``cube'' does not reference a specific size or shape.

[[Page 908]]

    Energy use means the total energy consumed, stated in kilowatt hours 
per one-hundred pounds (kWh/100 lb) of ice stated in multiples of 0.1. 
For remote condensing (but not remote compressor) automatic commercial 
ice makers and remote condensing and remote compressor automatic 
commercial ice makers, total energy consumed shall include the energy 
use of the ice-making mechanism, the compressor, and the remote 
condenser or condensing unit.
    Harvest rate means the amount of ice (at 32 degrees F) in pounds 
produced per 24 hours.
    Ice hardness factor means the latent heat capacity of harvested ice, 
in British thermal units per pound of ice (Btu/lb), divided by 144 Btu/
lb, expressed as a percent.
    Ice-making head means automatic commercial ice makers that do not 
contain integral storage bins, but are generally designed to accommodate 
a variety of bin capacities. Storage bins entail additional energy use 
not included in the reported energy consumption figures for these units.
    Maximum condenser water use means the maximum amount of water used 
by the condensing unit (if water-cooled), stated in gallons per 100 
pounds (gal/100 lb) of ice, in multiples of 1.
    Remote compressor means a type of automatic commercial ice maker in 
which the ice-making mechanism and compressor are in separate sections.
    Remote condensing means a type of automatic commercial ice maker in 
which the ice-making mechanism and condenser or condensing unit are in 
separate sections.
    Self-contained means a type of automatic commercial ice maker in 
which the ice-making mechanism and storage compartment are in an 
integral cabinet.

Sec. 431.134  Uniform test methods for the measurement of energy
and water consumption of automatic commercial ice makers.

    (a) Scope. This section provides the test procedures for measuring, 
pursuant to EPCA, the energy use in kilowatt hours per 100 pounds of ice 
(kWh/100 lb ice) and the condenser water use in gallons per 100 pounds 
of ice (gal/100 lb ice) of automatic commercial ice makers with 
capacities between 50 and 4,000 pounds of ice per 24 hours.
    (b) Testing and Calculations. Measure the energy use and the 
condenser water use of each covered product by conducting the test 
procedures set forth in AHRI 810, section 3, ``Definitions,'' section 4, 
``Test Requirements,'' and section 5, ``Rating Requirements'' 
(incorporated by reference, see Sec. 431.133). Where AHRI 810 
references ``ASHRAE Standard 29,'' ANSI/ASHRAE Standard 29-2009 
(incorporated by reference, see Sec. 431.133) shall be used. All 
references to cube type ice makers in AHRI 810 apply to all batch type 
automatic commercial ice makers.
    (1) For batch type automatic commercial ice makers, the energy use 
and condenser water use will be reported as measured in this paragraph 
(b), including the energy and water consumption, as applicable, of the 
ice-making mechanism, the compressor, and the condenser or condensing 
unit.
    (2)(i) For continuous type automatic commercial ice makers, 
determine the energy use and condenser water use by multiplying the 
energy consumption or condenser water use as measured in this paragraph 
(b) by the ice hardness adjustment factor, determined using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR11JA12.048

    (ii) Determine the ice hardness factor by following the procedure 
specified in the ``Procedure for Determining Ice Quality'' in section 
A.3 of normative annex A of ANSI/ASHRAE 29 (incorporated by reference, 
see Sec. 431.133), except that the test shall be conducted at an 
ambient air temperature of 70 [deg]F 1 [deg]F, 
with an initial water temperature of 90 [deg]F 1 
[deg]F, and weights shall be accurate to within 2 
percent of the quantity measured. The ice hardness factor is equivalent 
to the corrected net cooling effect per pound of ice, line 19 in ANSI/
ASHRAE 29 Table A1, where the calorimeter constant used in line 18 shall 
be that determined in section A2 using seasoned, block ice.

Sec. 431.192  Definitions.

    The following definitions apply for purposes of this subpart:
    Autotransformer means a transformer that:
    (1) Has one physical winding that consists of a series winding part 
and a common winding part;
    (2) Has no isolation between its primary and secondary circuits; and
    (3) During step-down operation, has a primary voltage that is equal 
to the total of the series and common winding voltages, and a secondary 
voltage that is equal to the common winding voltage.
    Basic model means a group of models of distribution transformers 
manufactured by a single manufacturer, that have the same insulation 
type (i.e., liquid-immersed or dry-type), have the same number of phases 
(i.e., single or three), have the same standard kVA rating, and do not 
have any differentiating electrical, physical or functional features 
that affect energy consumption. Differences in voltage and differences 
in basic impulse insulation level (BIL) rating are examples of 
differentiating electrical features that affect energy consumption.
    Distribution transformer means a transformer that--
    (1) Has an input voltage of 34.5 kV or less;
    (2) Has an output voltage of 600 V or less;
    (3) Is rated for operation at a frequency of 60 Hz; and
    (4) Has a capacity of 10 kVA to 2500 kVA for liquid-immersed units 
and 15 kVA to 2500 kVA for dry-type units; but
    (5) The term ``distribution transformer'' does not include a 
transformer that is an--
    (i) Autotransformer;
    (ii) Drive (isolation) transformer;
    (iii) Grounding transformer;
    (iv) Machine-tool (control) transformer;
    (v) Nonventilated transformer;

    (xi) Transformer with tap range of 20 percent or more;
    (xii) Uninterruptible power supply transformer; or
    (xiii) Welding transformer.
    Drive (isolation) transformer means a transformer that:
    (1) Isolates an electric motor from the line;
    (2) Accommodates the added loads of drive-created harmonics; and
    (3) Is designed to withstand the additional mechanical stresses 
resulting from an alternating current adjustable frequency motor drive 
or a direct current motor drive.
    Efficiency means the ratio of the useful power output to the total 
power input.
    Excitation current or no-load current means the current that flows 
in any winding used to excite the transformer when all other windings 
are open-circuited.
    Grounding transformer means a three-phase transformer intended 
primarily

[[Page 913]]

to provide a neutral point for system-grounding purposes, either by 
means of:
    (1) A grounded wye primary winding and a delta secondary winding; or
    (2) A transformer with its primary winding in a zig-zag winding 
arrangement, and with no secondary winding.
    Liquid-immersed distribution transformer means a distribution 
transformer in which the core and coil assembly is immersed in an 
insulating liquid.
    Load loss means, for a distribution transformer, those losses 
incident to a specified load carried by the transformer, including 
losses in the windings as well as stray losses in the conducting parts 
of the transformer.
    Low-voltage dry-type distribution transformer means a distribution 
transformer that--
    (1) Has an input voltage of 600 volts or less;
    (2) Is air-cooled; and
    (3) Does not use oil as a coolant.
    Machine-tool (control) transformer means a transformer that is 
equipped with a fuse or other over-current protection device, and is 
generally used for the operation of a solenoid, contactor, relay, 
portable tool, or localized lighting.
    Medium-voltage dry-type distribution transformer means a 
distribution transformer in which the core and coil assembly is immersed 
in a gaseous or dry-compound insulating medium, and which has a rated 
primary voltage between 601 V and 34.5 kV.
    Mining distribution transformer means a medium-voltage dry-type 
distribution transformer that is built only for installation in an 
underground mine or surface mine, inside equipment for use in an 
underground mine or surface mine, on-board equipment for use in an 
underground mine or surface mine, or for equipment used for digging, 
drilling, or tunneling underground or above ground, and that has a 
nameplate which identifies the transformer as being for this use only.
    No-load loss means those losses that are incident to the excitation 
of the transformer.
    Nonventilated transformer means a transformer constructed so as to 
prevent external air circulation through the coils of the transformer 
while operating at zero gauge pressure.
    Phase angle means the angle between two phasors, where the two 
phasors represent progressions of periodic waves of either:
    (1) Two voltages;
    (2) Two currents; or
    (3) A voltage and a current of an alternating current circuit.
    Phase angle correction means the adjustment (correction) of 
measurement data to negate the effects of phase angle error.
    Phase angle error means incorrect displacement of the phase angle, 
introduced by the components of the test equipment.
    Rectifier transformer means a transformer that operates at the 
fundamental frequency of an alternating-current system and that is 
designed to have one or more output windings connected to a rectifier.
    Reference temperature means 20 [deg]C for no-load loss, 55 [deg]C 
for load loss of liquid-immersed distribution transformers at 50 percent 
load, and 75 [deg]C for load loss of both low-voltage and medium-voltage 
dry-type distribution transformers, at 35 percent load and 50 percent 
load, respectively. It is the temperature at which the transformer 
losses must be determined, and to which such losses must be corrected if 
testing is done at a different point. (These temperatures are specified 
in the test method in appendix A to this part.)
    Regulating transformer means a transformer that varies the voltage, 
the phase angle, or both voltage and phase angle, of an output circuit 
and compensates for fluctuation of load and input voltage, phase angle 
or both voltage and phase angle.
    Sealed transformer means a transformer designed to remain 
hermetically sealed under specified conditions of temperature and 
pressure.
    Special-impedance transformer means any transformer built to operate 
at an impedance outside of the normal impedance range for that 
transformer's kVA rating. The normal impedance range for each kVA rating 
for liquid-immersed and dry-type transformers is shown in Tables 1 and 
2, respectively.

percent more than the lowest, computed based on the sum of the 
deviations of the voltages of these taps from the transformer's nominal 
voltage.
    Uninterruptible power supply transformer means a transformer that is 
used within an uninterruptible power system, which in turn supplies 
power to loads that are sensitive to power failure, power sags, over 
voltage, switching transients, line noise, and other power quality

                            1.0 Definitions.

    The definitions contained in Sec. Sec. 431.2 and 431.192 are 
applicable to this appendix A.

                       2.0 Accuracy Requirements.

    (a) Equipment and methods for loss measurement shall be sufficiently 
accurate that measurement error will be limited to the values shown in 
Table 2.1.

    (b) Only instrument transformers meeting the 0.3 metering accuracy 
class, or better, may be used under this test method.

                       3.0 Resistance Measurements

    3.1 General Considerations
    (a) Measure or establish the winding temperature at the time of the 
winding resistance measurement.
    (b) Measure the direct current resistance (Rdc) of 
transformer windings by one of the methods outlined in section 3.3. The 
methods of section 3.5 must be used to correct load losses to the 
applicable reference temperature from the temperature at which they are 
measured. Observe precautions while taking measurements, such as those 
in section 3.4, in order to maintain measurement uncertainty limits 
specified in Table 2.1.
    3.2 Temperature Determination of Windings and Pre-conditions for 
Resistance Measurement.
    Make temperature measurements in protected areas where the air 
temperature is stable and there are no drafts. Determine the winding 
temperature (Tdc) for liquid-immersed and dry-type 
distribution transformers by the methods described in sections 3.2.1 and 
3.2.2, respectively.
    3.2.1 Liquid-Immersed Distribution Transformers.

                             3.2.1.1 Methods

    Record the winding temperature (Tdc) of liquid-immersed 
transformers as the average of either of the following:
    (a) The measurements from two temperature sensing devices (for 
example, thermocouples) applied to the outside of the transformer tank 
and thermally insulated from the surrounding environment, with one 
located at the level of the oil and the other located near the tank 
bottom or at the lower radiator header if applicable; or
    (b) The measurements from two temperature sensing devices immersed 
in the transformer liquid, with one located directly above the winding 
and other located directly below the winding.

                           3.2.1.2 Conditions

    Make this determination under either of the following conditions:
    (a) The windings have been under insulating liquid with no 
excitation and no current in the windings for four hours before the dc 
resistance is measured; or
    (b) The temperature of the insulating liquid has stabilized, and the 
difference between the top and bottom temperature does not exceed 5 
[deg]C.
    3.2.2 Dry-Type Distribution Transformers.
    Record the winding temperature (Tdc) of dry-type 
transformers as either of the following:
    (a) For ventilated dry-type units, use the average of readings of 
four or more thermometers, thermocouples, or other suitable temperature 
sensors inserted within the coils. Place the sensing points of the 
measuring devices as close as possible to the winding conductors. For 
sealed units, such as epoxy-coated or epoxy-encapsulated units, use the 
average of four or more temperature sensors located on the enclosure 
and/or cover, as close to different parts of the winding assemblies as 
possible; or
    (b) For both ventilated and sealed units, use the ambient 
temperature of the test area, under the following conditions:
    (1) All internal temperatures measured by the internal temperature 
sensors must not differ from the test area ambient temperature by more 
than 2 [deg]C.
    (2) Enclosure surface temperatures for sealed units must not differ 
from the test area ambient temperature by more than 2 [deg]C.
    (3) Test area ambient temperature should not have changed by more 
than 3 [deg]C for 3 hours before the test.
    (4) Neither voltage nor current has been applied to the unit under 
test for 24 hours. In addition, increase this initial 24 hour period by 
any added amount of time necessary for the temperature of the 
transformer windings

[[Page 918]]

to stabilize at the level of the ambient temperature. However, this 
additional amount of time need not exceed 24 hours.
    3.3 Resistance Measurement Methods.
    Make resistance measurements using either the resistance bridge 
method, the voltmeter-ammeter method or a resistance meter. In each 
instance when this Uniform Test Method is used to test more than one 
unit of a basic model to determine the efficiency of that basic model, 
the resistance of the units being tested may be determined from making 
resistance measurements on only one of the units.
    3.3.1 Resistance Bridge Methods.
    If the resistance bridge method is selected, use either the 
Wheatstone or Kelvin bridge circuit (or the equivalent of either).

                        3.3.1.1 Wheatstone Bridge

    (a) This bridge is best suited for measuring resistances larger than 
ten ohms. A schematic diagram of a Wheatstone bridge with a 
representative transformer under test is shown in Figure 3.1.
[GRAPHIC] [TIFF OMITTED] TR27AP06.002

Where:

Rdc is the resistance of the transformer winding being 
          measured,
Rs is a standard resistor having the resistance 
          Rs,
Ra, Rb are two precision resistors with resistance 
          values Ra and Rb , respectively; at 
          least one resistor must have a provision for resistance 
          adjustment,
Rt is a resistor for reducing the time constant of the 
          circuit,
D is a null detector, which may be either a micro ammeter or 
          microvoltmeter or equivalent instrument for observing that no 
          signal is present when the bridge is balanced, and
Vdc is a source of dc voltage for supplying the power to the 
          Wheatstone Bridge.

    (b) In the measurement process, turn on the source (Vdc), 
and adjust the resistance ratio (Ra/Rb) to produce 
zero signal at the detector (D). Determine the winding resistance by 
using equation 3-1 as follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.003

                          3.3.1.2 Kelvin Bridge

    (a) This bridge separates the resistance of the connecting 
conductors to the transformer winding being measured from the resistance 
of the winding, and therefore is best suited for measuring resistances 
of ten ohms and smaller. A schematic diagram of a Kelvin bridge with a 
representative transformer under test is shown in Figure 3.2.

[[Page 919]]

[GRAPHIC] [TIFF OMITTED] TR27AP06.004

    (b) The Kelvin Bridge has seven of the same type of components as in 
the Wheatstone Bridge. It has two more resistors than the Wheatstone 
bridge, Ra1 and Rb1. At least one of these 
resistors must have adjustable resistance. In the measurement process, 
the source is turned on, two resistance ratios (Ra/
Rb) and (Ra1/Rb1) are adjusted to be 
equal, and then the two ratios are adjusted together to balance the 
bridge producing zero signal at the detector. Determine the winding 
resistance by using equation 3-2 as follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.005

as with the Wheatstone bridge, with an additional condition that:
[GRAPHIC] [TIFF OMITTED] TR27AP06.006

    (c) The Kelvin bridge provides two sets of leads, current-carrying 
and voltage-sensing, to the transformer terminals and the standard 
resistor, thus eliminating voltage drops from the measurement in the 
current-carrying leads as represented by Rd.
    3.3.2 Voltmeter-Ammeter Method.
    (a) Employ the voltmeter-ammeter method only if the rated current of 
the winding is greater than one ampere and the test current is limited 
to 15 percent of the winding current. Connect the transformer winding 
under test to the circuit shown in Figure 3.3.

[[Page 920]]

[GRAPHIC] [TIFF OMITTED] TR27AP06.007

Where:

A is an ammeter or a voltmeter-shunt combination for measuring the 
          current (Imdc) in the transformer winding,
V is a voltmeter with sensitivity in the millivolt range for measuring 
          the voltage (Vmdc) applied to the transformer 
          winding,
Rdc is the resistance of the transformer winding being 
          measured,
Rt is a resistor for reducing the time constant of the 
          circuit, and
Vdc is a source of dc voltage for supplying power to the 
          measuring circuit.

    (b) To perform the measurement, turn on the source to produce 
current no larger than 15 percent of the rated current for the winding. 
Wait until the current and voltage readings have stabilized and then 
take simultaneous readings of voltage and current. Determine the winding 
resistance Rdc by using equation 3-4 as follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.008

Where:

Vmdc is the voltage measured by the voltmeter V, and
Imdc is the current measured by the ammeter A.

    (c) As shown in Figure 3.3, separate current and voltage leads must 
be brought to the transformer terminals. (This eliminates the errors due 
to lead and contact resistance.)
    3.3.3 Resistance Meters.
    Resistance meters may be based on voltmeter-ammeter, or resistance 
bridge, or some other operating principle. Any meter used to measure a 
transformer's winding resistance must have specifications for resistance 
range, current range, and ability to measure highly inductive resistors 
that cover the characteristics of the transformer being tested. Also the 
meter's specifications for accuracy must meet the applicable criteria of 
Table 2.1 in section 2.0.
    3.4 Precautions in Measuring Winding Resistance.
    3.4.1 Required actions.
    The following guidelines must be observed when making resistance 
measurements:
    (a) Use separate current and voltage leads when measuring small (<10 
ohms) resistance.
    (b) Use null detectors in bridge circuits, and measuring instruments 
in voltmeter-ammeter circuits, that have sensitivity and resolution 
sufficient to enable observation of at least 0.1 percent change in the 
measured resistance.
    (c) Maintain the dc test current at or below 15 percent of the rated 
winding current.
    (d) Inclusion of a stabilizing resistor Rt (see section 
3.4.2) will require higher source voltage.
    (e) Disconnect the null detector (if a bridge circuit is used) and 
voltmeter from the circuit before the current is switched off, and 
switch off current by a suitable insulated switch.
    3.4.2 Guideline for Time Constant.
    (a) The following guideline is suggested for the tester as a means 
to facilitate the measurement of resistance in accordance with the 
accuracy requirements of section 2.0:
    (b) The accurate reading of resistance Rdc may be 
facilitated by shortening the time constant. This is done by introducing 
a resistor Rt in series with the winding under test in both 
the bridge and voltmeter-ammeter circuits as shown in Figures 3.1 to 
3.3. The relationship for the time constant is:
[GRAPHIC] [TIFF OMITTED] TR27AP06.009


[[Page 921]]


Where:

Tc is the time constant in seconds,
Ltc is the total magnetizing and leakage inductance of the 
          winding under test, in henries, and
Rtc is the total resistance in ohms, consisting of 
          Rt in series with the winding resistance 
          Rdc and the resistance Rs of the 
          standard resistor in the bridge circuit.

    (c) Because Rtc is in the denominator of the expression 
for the time constant, increasing the resistance Rtc will 
decrease the time constant. If the time constant in a given test circuit 
is too long for the resistance readings to be stable, then a higher 
resistance can be substituted for the existing Rtc, and 
successive replacements can be made until adequate stability is reached.
    3.5 Conversion of Resistance Measurements.
    (a) Resistance measurements must be corrected, from the temperature 
at which the winding resistance measurements were made, to the reference 
temperature. As specified in these test procedures, the reference 
temperature for liquid-immersed transformers loaded at 50 percent of the 
rated load is 55 [deg]C. For medium-voltage, dry-type transformers 
loaded at 50 percent of the rated load, and for low-voltage, dry-type 
transformers loaded at 35 percent of the rated load, the reference 
temperature is 75 [deg]C.
    (b) Correct the measured resistance to the resistance at the 
reference temperature using equation 3-6 as follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.010

Where:

Rts is the resistance at the reference temperature, 
          Ts,
Rdc is the measured resistance at temperature, 
          Tdc,
Ts is the reference temperature in [deg]C,
Tdc is the temperature at which resistance was measured in 
          [deg]C, and
Tk is 234.5 [deg]C for copper or 225 [deg]C for aluminum.

                          4.0 Loss Measurement

    4.1 General Considerations.
    The efficiency of a transformer is computed from the total 
transformer losses, which are determined from the measured value of the 
no-load loss and load loss power components. Each of these two power 
loss components is measured separately using test sets that are 
identical, except that shorting straps are added for the load-loss test. 
The measured quantities will need correction for instrumentation losses 
and may need corrections for known phase angle errors in measuring 
equipment and for the waveform distortion in the test voltage. Any power 
loss not measured at the applicable reference temperature must be 
adjusted to that reference temperature. The measured load loss must also 
be adjusted to a specified output loading level if not measured at the 
specified output loading level. Test distribution transformers designed 
for harmonic currents using a sinusoidal waveform (k = 1).
    4.2 Measurement of Power Losses.
    4.2.1 No-Load Loss.
    Measure the no-load loss and apply corrections as described in 
section 4.4, using the appropriate test set as described in section 4.3.
    4.2.2 Load Loss.
    Measure the load loss and apply corrections as described in section 
4.5, using the appropriate test set as described in section 4.3.
    4.3 Test Sets.
    (a) The same test set may be used for both the no-load loss and load 
loss measurements provided the range of the test set encompasses the 
test requirements of both tests. Calibrate the test set to national 
standards to meet the tolerances in Table 2.1 in section 2.0. In 
addition, the wattmeter, current measuring system and voltage measuring 
system must be calibrated separately if the overall test set calibration 
is outside the tolerance as specified in section 2.0 or the individual 
phase angle error exceeds the values specified in section 4.5.3.
    (b) A test set based on the wattmeter-voltmeter-ammeter principle 
may be used to measure the power loss and the applied voltage and 
current of a transformer where the transformer's test current and 
voltage are within the measurement capability of the measuring 
instruments. Current and voltage transformers, known collectively as 
instrument transformers, or other scaling devices such as resistive or 
capacitive dividers for voltage, may be used in the above circumstance, 
and must be used together with instruments to measure current, voltage, 
or power where the current or voltage of the transformer under test 
exceeds the measurement capability of such instruments. Thus, a test set 
may include a combination of measuring instruments and instrument 
transformers (or other scaling devices), so long as the current or 
voltage of the transformer under test does not exceed the measurement 
capability of any of the instruments.
    4.3.1 Single-Phase Test Sets.
    Use these for testing single-phase distribution transformers.
    4.3.1.1 Without Instrument Transformers.
    (a) A single-phase test set without an instrument transformer is 
shown in Figure 4.1.

[[Page 922]]

[GRAPHIC] [TIFF OMITTED] TR27AP06.011

Where:

W is a wattmeter used to measure Pnm and Plm, the 
          no-load and load loss power, respectively,
Vrms is a true root-mean-square (rms) voltmeter used to 
          measure Vr(nm) and Vlm, the rms test 
          voltages in no-load and load loss measurements, respectively,
Vav is an average sensing voltmeter, calibrated to indicate 
          rms voltage for sinusoidal waveforms and used to measure 
          Va(nm), the average voltage in no-load loss 
          measurements,
A is an rms ammeter used to measure test current, especially 
          Ilm, the load loss current, and
(SC) is a conductor for providing a short-circuit across the output 
          windings for the load loss measurements.

    (b) Either the primary or the secondary winding can be connected to 
the test set. However, more compatible voltage and current levels for 
the measuring instruments are available if for no-load loss measurements 
the secondary (low voltage) winding is connected to the test set, and 
for load loss measurements the primary winding is connected to the test 
set. Use the average-sensing voltmeter, Vav, only in no-load 
loss measurements.
    4.3.1.2 With Instrument Transformers.
    A single-phase test set with instrument transformers is shown in 
Figure 4.2. This circuit has the same four measuring instruments as that 
in Figure 4.1. The current and voltage transformers, designated as (CT) 
and (VT), respectively, are added.
[GRAPHIC] [TIFF OMITTED] TR27AP06.012

    4.3.2 Three-Phase Test Sets.
    Use these for testing three-phase distribution transformers. Use in 
a four-wire, three-wattmeter test circuit.
    4.3.2.1 Without Instrument Transformers.
    (a) A three-phase test set without instrument transformers is shown 
in Figure 4.3. This test set is essentially the same circuit

[[Page 923]]

shown in Figure 4.1 repeated three times, and the instruments are 
individual devices as shown. As an alternative, the entire 
instrumentation system of a three-phase test set without transformers 
may consist of a multi-function analyzer.
[GRAPHIC] [TIFF OMITTED] TR27AP06.013

    (b) Either group of windings, the primary or the secondary, can be 
connected in wye or delta configuration. If both groups of windings are 
connected in the wye configuration for the no-load test, the neutral of 
the winding connected to the test set must be connected to the neutral 
of the source to provide a return path for the neutral current.
    (c) In the no-load loss measurement, the voltage on the winding must 
be measured. Therefore a provision must be made to switch the voltmeters 
for line-to-neutral measurements for wye-connected windings and for 
line-to-line measurements for delta-connected windings.
    4.3.2.2 With Instrument Transformers.
    A three-phase test set with instrument transformers is shown in 
Figure 4.4. This test set is essentially the same circuit shown in 
Figure 4.2 repeated three times. Provision must be made to switch the 
voltmeters for line-to-neutral and line-to-line measurements as in 
section 4.3.2.1. The voltage sensors (``coils'') of the wattmeters must 
always be connected in the line-to-neutral configuration.

[[Page 924]]

[GRAPHIC] [TIFF OMITTED] TR27AP06.014

    4.3.2.3 Test Set Neutrals.
    If the power source in the test circuit is wye-connected, ground the 
neutral. If the power source in the test circuit is delta-connected, use 
a grounding transformer to obtain neutral and ground for the test.
    4.4 No-Load Losses: Measurement and Calculations.
    4.4.1 General Considerations.
    Measurement corrections are permitted but not required for 
instrumentation losses and for losses from auxiliary devices. 
Measurement corrections are required:
    (a) When the waveform of the applied voltage is non-sinusoidal; and
    (b) When the core temperature or liquid temperature is outside the 
20 [deg]C 10 [deg]C range.
    4.4.2 No-Load Loss Test.
    (a) The purpose of the no-load loss test is to measure no-load 
losses at a specified excitation voltage and a specified frequency. The 
no-load loss determination must be based on a sine-wave voltage 
corrected to the reference temperature. Connect either of the 
transformer windings, primary or secondary, to the appropriate test set 
of Figures 4.1 to 4.4, giving consideration to section 4.4.2(a)(2). 
Leave the unconnected winding(s) open circuited. Apply the rated voltage 
at rated frequency, as measured by the average-sensing voltmeter, to the 
transformer. Take the readings of the wattmeter(s) and the average-
sensing and true rms voltmeters. Observe the following precautions:
    (1) Voltmeter connections. When correcting to a sine-wave basis 
using the average-voltmeter method, the voltmeter connections must be 
such that the waveform applied to the voltmeters is the same as the 
waveform across the energized windings.
    (2) Energized windings. Energize either the high voltage or the low 
voltage winding of the transformer under test.
    (3) Voltage and frequency. The no-load loss test must be conducted 
with rated voltage impressed across the transformer terminals using a 
voltage source at a frequency equal to the rated frequency of the 
transformer under test.
    (b) Adjust the voltage to the specified value as indicated by the 
average-sensing voltmeter. Record the values of rms voltage, rms 
current, electrical power, and average voltage as close to 
simultaneously as possible. For a three-phase transformer, take all of 
the readings on one phase before proceeding to the next, and record the 
average of the three rms voltmeter readings as the rms voltage value.
    Note: When the tester uses a power supply that is not synchronized 
with an electric utility grid, such as a dc/ac motor-generator

[[Page 925]]

set, check the frequency and maintain it within 0.5 percent of the rated frequency of the transformer 
under test. A power source that is directly connected to, or 
synchronized with, an electric utility grid need not be monitored for 
frequency.
    4.4.3 Corrections.
    4.4.3.1 Correction for Instrumentation Losses.
    Measured losses attributable to the voltmeters and wattmeter voltage 
circuit, and to voltage transformers if they are used, may be deducted 
from the total no-load losses measured during testing.
    4.4.3.2 Correction for Non-Sinusoidal Applied Voltage.
    (a) The measured value of no-load loss must be corrected to a 
sinusoidal voltage, except when waveform distortion in the test voltage 
causes the magnitude of the correction to be less than 1 percent. In 
such a case, no correction is required.
    (b) To make a correction where the distortion requires a correction 
of 5 percent or less, use equation 4-1. If the distortion requires a 
correction to be greater than 5 percent, improve the test voltage and 
re-test. Repeat until the distortion requires a correction of 5 percent 
or less.
    (c) Determine the no-load losses of the transformer corrected for 
sine-wave basis from the measured value by using equation 4-1 as 
follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.015

Where:

Pncl is the no-load loss corrected to a sine-wave basis at 
          the temperature (Tnm) at which no-load loss is 
          measured,
Pnm is the measured no-load loss at temperature 
          Tnm,
P1 is the per unit hysteresis loss,
P2 is the per unit eddy-current loss,
P1 + P2 = 1,
[GRAPHIC] [TIFF OMITTED] TR27AP06.016

Vr(nm) is the test voltage measured by rms voltmeter, and
Va(nm) is the test voltage measured by average-voltage 
          voltmeter.
    (d) The two loss components (P1 and P2) are 
assumed equal in value, each assigned a value of 0.5 per unit, unless 
the actual measurement-based values of hysteresis and eddy-current 
losses are available (in per unit form), in which case the actual 
measurements apply.
    4.4.3.3 Correction of No-Load Loss to Reference Temperature.
    After correcting the measured no-load loss for waveform distortion, 
correct the loss to the reference temperature of 20 [deg]C. If the no-
load loss measurements were made between 10 [deg]C and 30 [deg]C, this 
correction is not required. If the correction to reference temperature 
is applied, then the core temperature of the transformer during no-load 
loss measurement (Tnm) must be determined within 10 [deg]C of the true average core temperature. Correct 
the no-load loss to the reference temperature by using equation 4-2 as 
follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.017

Where:

Pnc is the no-load losses corrected for waveform distortion 
          and then to the reference temperature of 20 [deg]C,
Pnc1 is the no-load losses, corrected for waveform 
          distortion, at temperature Tnm,
Tnm is the core temperature during the measurement of no-load 
          losses, and
Tnr is the reference temperature, 20 [deg]C.

    4.5 Load Losses: Measurement and Calculations.
    4.5.1 General Considerations.
    (a) The load losses of a transformer are those losses incident to a 
specified load carried by the transformer. Load losses consist of ohmic 
loss in the windings due to the load current and stray losses due to the 
eddy currents induced by the leakage flux in the windings, core clamps, 
magnetic shields, tank walls, and other conducting parts. The ohmic loss 
of a transformer varies directly with temperature, whereas the stray 
losses vary inversely with temperature.
    (b) For a transformer with a tap changer, conduct the test at the 
rated current and rated-voltage tap position. For a transformer that has 
a configuration of windings which allows for more than one nominal rated 
voltage, determine its load losses either in the winding configuration 
in which the highest losses occur or in each winding configuration in 
which the transformer can operate.
    4.5.2 Tests for Measuring Load Losses.
    (a) Connect the transformer with either the high-voltage or low-
voltage windings to the appropriate test set. Then short-circuit the 
winding that was not connected to the test set. Apply a voltage at the 
rated frequency (of the transformer under test) to the connected 
windings to produce the rated current in the transformer. Take the 
readings of the wattmeter(s), the ammeters(s), and rms voltmeter(s).
    (b) Regardless of the test set selected, the following preparatory 
requirements must be satisfied for accurate test results:
    (1) Determine the temperature of the windings using the applicable 
method in section 3.2.1 or section 3.2.2.
    (2) The conductors used to short-circuit the windings must have a 
cross-sectional

[[Page 926]]

area equal to, or greater than, the corresponding transformer leads, or, 
if the tester uses a different method to short-circuit the windings, the 
losses in the short-circuiting conductor assembly must be less than 10 
percent of the transformer's load losses.
    (3) When the tester uses a power supply that is not synchronized 
with an electric utility grid, such as a dc/ac motor-generator set, 
follow the provisions of the ``Note'' in section 4.4.2.
    4.5.3 Corrections.
    4.5.3.1 Correction for Losses from Instrumentation and Auxiliary 
Devices.
    4.5.3.1.1 Instrumentation Losses.
    Measured losses attributable to the voltmeters, wattmeter voltage 
circuit and short-circuiting conductor (SC), and to the voltage 
transformers if they are used, may be deducted from the total load 
losses measured during testing.
    4.5.3.1.2 Losses from Auxiliary Devices.
    Measured losses attributable to auxiliary devices (e.g., circuit 
breakers, fuses, switches) installed in the transformer, if any, that 
are not part of the winding and core assembly, may be excluded from load 
losses measured during testing. To exclude these losses, either (1) 
measure transformer losses without the auxiliary devices by removing or 
by-passing them, or (2) measure transformer losses with the auxiliary 
devices connected, determine the losses associated with the auxiliary 
devices, and deduct these losses from the load losses measured during 
testing.
    4.5.3.2 Correction for Phase Angle Errors.
    (a) Corrections for phase angle errors are not required if the 
instrumentation is calibrated over the entire range of power factors and 
phase angle errors. Otherwise, determine whether to correct for phase 
angle errors from the magnitude of the normalized per unit correction, 
[beta]n, obtained by using equation 4-3 as follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.018

    (b) The correction must be applied if [beta]n is outside 
the limits of 0.01. If [beta]n is 
within the limits of 0.01, the correction is 
permitted but not required.
    (c) If the correction for phase angle errors is to be applied, first 
examine the total system phase angle ([beta]w - 
[beta]v + [beta]c). Where the total system phase 
angle is equal to or less than 12 milliradians 
(41 minutes), use either equation 4-4 or 4-5 to 
correct the measured load loss power for phase angle errors, and where 
the total system phase angle exceeds 12 
milliradians (41 minutes) use equation 4-5, as 
follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.019

          the voltage and current phasors as sensed by the wattmeter is 
          smaller than the true phase angle, thus effectively increasing 
          the measured power,
[beta]v is the phase angle error (in radians) of the voltage 
          transformer; the error is positive if the secondary voltage 
          leads the primary voltage, and
[beta]c is the phase angle error (in radians) of the current 
          transformer; the error is positive if the secondary current 
          leads the primary current.

    (e) The instrumentation phase angle errors used in the correction 
equations must be specific for the test conditions involved.
    4.5.3.3 Temperature Correction of Load Loss.
    (a) When the measurement of load loss is made at a temperature 
Tlm that is different from the reference temperature, use the 
procedure summarized in the equations 4-6 to 4-10 to correct the 
measured load loss to the reference temperature. The symbols used in 
these equations are defined at the end of this section.
    (b) Calculate the ohmic loss (Pe) by using equation 4-6 
as follows:


[[Page 927]]

    (c) Obtain the stray loss by subtracting the calculated ohmic loss 
from the measured load loss, by using equation 4-7 as follows:
[GRAPHIC] [TIFF OMITTED] TR27AP06.023

    (d) Correct the ohmic and stray losses to the reference temperature 
for the load loss by using equations 4-8 and 4-9, respectively, as 
follows:

temperature, to give the load loss, Plc2, at the reference 
temperature, by using equation 4-10 as follows:

          ohms,

          windings, Tk is 225 [deg]C; where both copper and

          voltage applied to the primary winding is the rated primary 
          voltage.

         5.0 Determining the Efficiency Value of the Transformer

    This section presents the equations to use in determining the 
efficiency value of the transformer at the required reference conditions 
and at the specified loading level. The details of measurements are 
described in sections 3.0 and 4.0. For a transformer that has a 
configuration of windings which allows for more than one nominal rated 
voltage, determine its efficiency either at the voltage at which the 
highest losses occur or at each voltage at which the transformer is 
rated to operate.
    5.1 Output Loading Level Adjustment.

Pts is as described and calculated in section 5.2.
    5.4 Significant Figures in Power Loss and Efficiency Data.
    In measured and calculated data, retain enough significant figures 
to provide at least 1 percent resolution in power loss data and 0.01 
percent resolution in efficiency data.

Sec. 431.264  Uniform test method to measure flow rate and spray force
of commercial prerinse spray valves.

    (a) Scope. This section provides the test procedure to measure the 
flow rate and spray force of a commercial prerinse spray valve.
    (b) Testing and calculations for a unit with a single spray 
setting--(1) Flow rate. (i) Test each unit in accordance with the 
requirements of sections 6.1 through 6.9 (Apparatus) (except 6.4 and 
6.7), 9.1 through 9.4 (Preparation of Apparatus), and 10.1 through 
10.2.5 (Procedure) of ASTM F2324-13, (incorporated by reference, see 
Sec. 431.263). Precatory

[[Page 934]]

language in the ASTM F2324-13 is to be treated as mandatory for the 
purpose of testing. In section 9.1 of ASTM F2324-13, the second instance 
of ``prerinse spray valve'' refers to the spring-style deck-mounted 
prerinse unit defined in section 6.8. In lieu of using manufacturer 
installation instructions or packaging, always connect the commercial 
prerinse spray valve to the flex tubing for testing. Normalize the 
weight of the water to calculate flow rate using Equation 1, where 
Wwater is the weight normalized to a 1 minute time period, 
W1 is the weight of the water in the carboy at the conclusion 
of the flow rate test, and t1 is the total recorded time of 
the flow rate test.
[GRAPHIC] [TIFF OMITTED] TR30DE15.004

    (ii) Perform calculations in accordance with section 11.3.1 
(Calculation and Report). Record the water temperature ([deg]F) and 
dynamic water pressure (psi) once at the start for each run of the test. 
Record the time (min), the normalized weight of water in the carboy (lb) 
and the resulting flow rate (gpm) once at the end of each run of the 
test. Record flow rate measurements of time (min) and weight (lb) at the 
resolutions of the test instrumentation. Perform three runs on each 
unit, as specified in section 10.2.5 of ASTM F2324-13, but disregard any 
references to Annex A1. Then, for each unit, calculate the mean of the 
three flow rate values determined from each run. Round the final value 
for flow rate to two decimal places and record that value.
    (2) Spray force. Test each unit in accordance with the test 
requirements specified in sections 6.2 and 6.4 through 6.9 (Apparatus), 
9.1 through 9.5.3.2 (Preparation of Apparatus), and 10.3.1 through 
10.3.8 (Procedure) of ASTM F2324-13. In section 9.1 of ASTM F2324-13, 
the second instance of ``prerinse spray valve'' refers to the spring-
style deck-mounted prerinse unit defined in section 6.8. In lieu of 
using manufacturer installation instructions or packaging, always 
connect the commercial prerinse spray valve to the flex tubing for 
testing. Record the water temperature ([deg]F) and dynamic water 
pressure (psi) once at the start for each run of the test. In order to 
calculate the mean spray force value for the unit under test, there are 
two measurements per run and there are three runs per test. For each run 
of the test, record a minimum of two spray force measurements and 
calculate the mean of the measurements over the 15-second time period of 
stabilized flow during spray force testing. Record the time (min) once 
at the end of each run of the test. Record spray force measurements at 
the resolution of the test instrumentation. Conduct three runs on each 
unit, as specified in section 10.3.8 of ASTM F2324-13, but disregard any 
references to Annex A1. Ensure the unit has been stabilized separately 
during each run. Then for each unit, calculate and record the mean of 
the spray force values determined from each run. Round the final value 
for spray force to one decimal place.
    (c) Testing and calculations for a unit with multiple spray 
settings. If a unit has multiple user-selectable spray settings, or 
includes multiple spray faces that can be installed, for each possible 
spray setting or spray face:
    (1) Measure both the flow rate and spray force according to 
paragraphs (b)(1) and (2) of this section (including calculating the 
mean flow rate and mean spray force) for each spray setting; and
    (2) Record the mean flow rate for each spray setting, rounded to two 
decimal places. Record the mean spray force for each spray setting, 
rounded to one decimal place.

    1. General. Section 3, ``Definitions''; section 4, ``Instruments''; 
section 5, ``Vendible Capacity''; section 6, ``Test Conditions''; 
section 7.1, ``Test Procedures--General Requirements''; and section 7.2, 
``Energy Consumption Test'' of ANSI/ASHRAE 32.1 (incorporated by 
reference; see Sec. 431.293) apply to this appendix except as noted 
throughout this appendix. In cases where there is a conflict, the 
language of the test procedure in this appendix takes precedence over 
ANSI/ASHRAE 32.1.
    1.1. Instruments. In addition to the instrument accuracy 
requirements in section 4, ``Instruments,'' of ANSI/ASHRAE 32.1 
(incorporated by reference, see Sec. 431.293), humidity shall be 
measured with a calibrated instrument accurate to 2 percent RH at the specified ambient relative humidity 
condition specified in section 2.1.2 of this appendix.
    1.2. Definitions. In addition to the definitions specified in 
section 3, ``Definitions,'' of ANSI/ASHRAE 32.1 (incorporated by 
reference, see Sec. 431.293), the following definition is also 
applicable to this appendix.
    External accessory standby mode means the mode of operation in which 
any external, integral customer display signs, lighting, or digital 
screens:
    (1) Are connected to mains power;
    (2) Do not produce the intended illumination, display, or 
interaction functionality; and
    (3) Can be switched into another mode automatically with only a 
remote user-generated or an internal signal.
    Instantaneous average next-to-vend beverage temperature means the 
spatial average of all standard test packages in the next-to-vend 
beverages positions at a given time.
    Integrated average temperature means the average temperature of all 
standard test package measurements in the next-to-vend beverage 
positions taken over the duration of the test, expressed in degrees 
Fahrenheit ([deg]F).
    Lowest application product temperature means the lowest integrated 
average temperature a given basic model is capable of maintaining so as 
to comply with the temperature stabilization requirements specified in 
section 7.2.2.2 of ANSI/ASHRAE 32.1 (incorporated by reference, see 
Sec. 431.293).
    2. Test Procedure.
    2.1. Test Conditions. The test conditions specified in section 6, 
``Test Conditions,'' of ANSI/ASHRAE 32.1 (incorporated by reference, see 
Sec. 431.293) apply to this appendix except that in section 6.1, 
``Voltage and Frequency,'' of ANSI/ASHRAE 32.1, the voltage and 
frequency tolerances specified in section 6.1.a of ANSI/ASHRAE 32.1 also 
apply equivalently to section 6.1.b of ANSI/ASHRAE 32.1 for equipment 
with dual nameplate voltages.
    2.1.1. Average Beverage Temperature. The integrated average 
temperature measured during the test must be within 1 [deg]F of the value specified in Table A.1 of this 
appendix or the lowest application product temperature for models tested 
in accordance with paragraph 2.1.3 of this appendix. The measurement of 
integrated average temperature must begin after temperature 
stabilization has been achieved and continue for the following 24 
consecutive hours. All references to ``Table 1'' in ANSI/ASHRAE 32.1 
(incorporated by reference, see Sec. 431.293) shall instead be 
interpreted as references to Table A.1 of this appendix and all 
references to ``average beverage temperature'' in ANSI/ASHRAE 32.1 shall 
instead be interpreted as references to the integrated average 
temperature as defined in section 1.2 of this appendix of this subpart, 
except as noted in section 2.1.1.1 of this appendix.
    2.1.1.1. Temperature Stabilization. Temperature stabilization shall 
be determined in accordance with section 7.2.2.2 of ANSI/ASHRAE 32.1 
(incorporated by reference Sec. 431.293), except that the reference to 
``average beverage temperature'' shall instead refer to the 
``instantaneous average next-to-vend beverage temperature,'' as defined 
in section 1.2 of this appendix, and the reference to ``Table 1'' shall 
instead refer to Table A.1 of this appendix. That is, temperature 
stabilization is considered to be achieved 24 hours after the 
instantaneous average next-to-vend beverage temperature reaches the 
specified value (see Table A.1) and energy consumption for two 
successive 6 hour periods are within 2 percent of each other.
    2.1.2. Ambient Test Conditions. The refrigerated bottled or canned 
beverage vending machine must be tested at the test conditions and 
tolerances specified in the following Table A.1 of this appendix. The 
specified ambient temperature and humidity conditions shall be 
maintained within the ranges specified for each recorded measurement. 
All references to ``Table 1'' in ANSI/ASHRAE 32.1 (incorporated by 
reference, see Sec. 431.293) shall instead be interpreted as references 
to Table A.1 of this appendix. In contrast to the requirements of 
section 6.1 and Table 1 of ANSI/ASHRAE 32.1, conduct testing only one 
time at the conditions referenced in Table A.1 of this appendix. Testing 
at alternate ambient conditions is not required or permitted.

    (2) The right-most next-to-vend product location, and
    (3) For equipment with greater than or equal to five next-to-vend 
product locations on each shelf, either:
    (A) The next-to-vend product location in the center of the shelf 
(i.e., equidistant from the left-most and right-most next-to-vend 
product locations) if there are an odd number of next-to-vend products 
on the shelf or
    (B) The next-to-vend product location immediately to the right and 
the left of the center position if there are an even number of next-to-
vend products on the shelf.
    (b) For even-numbered shelves, when counting from the bottom shelf, 
standard test packages shall be places at either:
    (1) For equipment with less than or equal to six next-to-vend 
product locations on each shelf, the next-to-vend product location(s):

    2.2.1.2. Placement of Standard Test Packages for Equipment with 
Products Arranged Vertically. For refrigerated bottled or canned 
beverage vending machines with products arranged vertically (e.g., in 
stacks), place standard test packages in the refrigerated compartment(s) 
in each next-to-vend product location.
    2.2.1.3. Loading of Combination Vending Machines. For combination 
vending machines, the non-refrigerated compartment(s) must not be loaded 
with any standard products, test packages, or other vendible 
merchandise.
    2.2.1.4. Standard Products. The standard product shall be standard 
12-ounce aluminum beverage cans filled with a liquid with a density of 
1.0 grams per milliliter (g/mL)  0.1 g/mL at 36 
[deg]F. For product storage racks that are not capable of vending 12-
ounce cans, but are capable of vending 20-ounce bottles, the standard 
product shall be 20-ounce plastic bottles filled with a liquid with a 
density of 1.0 g/mL  0.1 g/mL at 36 [deg]F. For 
product storage racks that are not capable of vending 12-ounce cans or 
20-ounce bottles, the standard product shall be the packaging and 
contents specified by the manufacturer in product literature as the 
standard product (i.e., the specific merchandise the refrigerated 
bottled or canned beverage vending machine is designed to vend).
    2.2.1.5. Standard Test Packages. A standard test package is a 
standard product, as specified in 2.2.1.4 of this appendix, altered to 
include a temperature-measuring instrument at its center of mass.
    2.2.2. Sensor Placement. The integrated average temperature of next-
to-vend beverages shall be measured in standard test packages in the 
next-to-vend product locations specified in section 2.2.1.1 of this 
appendix. Do not run the thermocouple wire and other measurement 
apparatus through the dispensing door; the thermocouple wire and other 
measurement apparatus must be configured and sealed so as to minimize 
air flow between the interior refrigerated volume and the ambient room 
air. If a manufacturer chooses to employ a method other than routing 
thermocouple and sensor wires through the door gasket and ensuring the 
gasket is compressed around the wire to ensure a good seal, then it must 
maintain a record of the method used in the data underlying that basic 
model's certification pursuant to 10 CFR 429.71.
    2.2.3. Accessories. (a) All standard components that would be used 
during normal operation of the model in the field and are necessary to 
provide sufficient functionality for

[[Page 941]]

cooling and vending products in field installations (i.e., product 
inventory, temperature management, product merchandising (including, 
e.g., lighting or signage), product selection, and product transport and 
delivery) shall be in place during testing and shall be set to the 
maximum energy-consuming setting if manually adjustable, except that the 
specific components and accessories listed in the subsequent sections 
shall be operated as stated. Components not necessary for the inventory, 
temperature management, product merchandising (e.g., lighting or 
signage), product selection, and or product transport and delivery shall 
be de-energized. If systems not required for the primary functionality 
of the machine as stated in this section cannot be de-energized without 
preventing the operation of the machine, then they shall be placed in 
the lowest energy consuming state.
    (b) Instead of testing pursuant to section 7.2.2.4 of ANSI/ASHRAE 
32.1 (incorporated by reference, see Sec. 431.293), provide, if 
necessary, any physical stimuli or other input to the machine needed to 
prevent automatic activation of energy management systems that can be 
adjusted by the machine operator during the test period. Automatic 
energy management systems that cannot be adjusted by the machine 
operator may be enabled, as specified by section 7.2.1 of ANSI/ASHRAE 
32.1.
    2.2.3.1. Payment Mechanisms. Refrigerated bottled or canned beverage 
vending machines shall be tested with no payment mechanism in place, the 
payment mechanism in place but de-energized, or the payment mechanism in 
place but set to the lowest energy consuming state, if it cannot be de-
energized. A default payment mechanism energy consumption value of 0.20 
kWh/day shall be added to the primary rated energy consumption per day, 
as required in section 2.3 of this appendix.
    2.2.3.2. Internal Lighting. All lighting that is contained within or 
is part of the internal physical boundary of the refrigerated bottled or 
canned beverage vending machine, as established by the top, bottom, and 
side panels of the equipment, shall be placed in its maximum energy 
consuming state.
    2.2.3.3. External Customer Display Signs, Lights, and Digital 
Screens. All external customer display signs, lights, and digital 
screens that are independent from the refrigeration or vending 
performance of the refrigerated bottled or canned beverage vending 
machine must be disconnected, disabled, or otherwise de-energized for 
the duration of testing. Customer display signs, lighting, and digital 
screens that are integrated into the beverage vending machine cabinet or 
controls such that they cannot be de-energized without disabling the 
refrigeration or vending functions of the refrigerated bottled or canned 
beverage vending machine or modifying the circuitry must be placed in 
external accessory standby mode, if available, or their lowest energy-
consuming state. Digital displays that also serve a vending or money 
processing function must be placed in the lowest energy-consuming state 
that still allows the money processing feature to function.
    2.2.3.4. Anti-sweat and Other Electric Resistance Heaters. Anti-
sweat and other electric resistance heaters must be operational during 
the entirety of the test procedure. Units with a user-selectable setting 
must have the heaters energized and set to the most energy-consumptive 
position. Units featuring an automatic, non-user-adjustable controller 
that turns on or off based on environmental conditions must be operating 
in the automatic state. Units that are not shipped with a controller 
from the point of manufacture, but are intended to be used with a 
controller, must be equipped with an appropriate controller when tested.
    2.2.3.5. Condensate Pan Heaters and Pumps. All electric resistance 
condensate heaters and condensate pumps must be installed and 
operational during the test. Prior to the start of the test, including 
the 24 hour period used to determine temperature stabilization, as 
described in ANSI/ASHRAE 32.1 section 7.2.2.2 (incorporated by 
reference, see Sec. 431.293), the condensate pan must be dry. For the 
duration of the test, including the 24 hour time period necessary for 
temperature stabilization, allow any condensate moisture generated to 
accumulate in the pan. Do not manually add or remove water from the 
condensate pan at any time during the test.
    2.2.3.6. Illuminated Temperature Displays. All illuminated 
temperature displays must be energized and operated during the test the 
same way they would be energized and operated during normal field 
operation, as recommended in manufacturer product literature, including 
manuals.
    2.2.3.7. Condenser Filters. Remove any nonpermanent filters provided 
to prevent particulates from blocking a model's condenser coil.
    2.2.3.8. Security Covers. Remove any devices used to secure the 
model from theft or tampering.
    2.2.3.9. General Purpose Outlets. During the test, do not connect 
any external load to any general purpose outlets available on a unit.
    2.2.3.10. Crankcase Heaters and Other Electric Resistance Heaters 
for Cold Weather. Crankcase heaters and other electric resistance 
heaters for cold weather must be operational during the test. If a 
control system, such as a thermostat or electronic controller, is used 
to modulate the operation of the heater, it must be activated during the 
test and operated in accordance with the manufacturer's instructions.
    2.2.4. Sampling and Recording of Data. Record the data listed in 
section 7.2.2.3 of

[[Page 942]]

ANSI/ASHRAE 32.1 (incorporated by reference, see Sec. 431.293) at least 
every 1 minute. For the purpose of this subsection, ``average beverage 
temperature,'' listed in section 7.2.2.3 of ANSI/ASHRAE 32.1, means 
``instantaneous average next-to-vend beverage temperature.''
    2.3. Determination of Daily Energy Consumption. Determine the daily 
energy consumption of each tested refrigerated bottled or canned 
beverage vending machine as the sum of:
    (a) The default payment mechanism energy consumption value from 
section 2.2.3.1 of this appendix and
    (b) The primary rated energy consumption per day (ED), in kWh, and 
determined in accordance with the calculation procedure in section 
7.2.3.1, ``Calculation of Daily Energy Consumption,'' of ANSI/ASHRAE 
32.1 (incorporated by reference, see Sec. 431.293).
    2.3.1. Calculations and Rounding. In all cases, the primary rated 
energy consumption per day (ED) must be calculated with raw measured 
values and rounded to units of 0.01 kWh/day.
    3. Determination of Refrigerated Volume, Vendible Capacity, and 
Surface Area.
    3.1. Refrigerated Volume. Determine the ``refrigerated volume'' of 
refrigerated bottled or canned beverage vending machines in accordance 
with appendix C, ``Measurement of Volume,'' of ANSI/ASHRAE 32.1 
(incorporated by reference, see Sec. 431.293). For combination vending 
machines, the ``refrigerated volume'' does not include any non-
refrigerated compartments.
    3.2. Vendible Capacity. Determine the ``vendible capacity'' of 
refrigerated bottled or canned beverage vending machines in accordance 
with the first paragraph of section 5, ``Vending Machine Capacity,'' of 
ANSI/ASHRAE 32.1, (incorporated by reference, see Sec. 431.293). For 
combination vending machines, the ``vendible capacity'' includes only 
the capacity of any portion of the refrigerated bottled or canned 
beverage vending machine that is refrigerated and does not include the 
capacity of the non-refrigerated compartment(s).

applicable to this appendix.
    Accessory low power mode means a state in which a beverage vending 
machine's lighting and/or other energy-using systems are in low power 
mode, but that is not a refrigeration low power mode. Functions that may 
constitute an accessory low power mode may include, for example, dimming 
or turning off lights, but does not include adjustment of the 
refrigeration system to elevate the temperature of the refrigerated 
compartment(s).
    External accessory standby mode means the mode of operation in which 
any external, integral customer display signs, lighting, or digital 
screens are connected to mains power; do not produce the intended 
illumination, display, or interaction functionality; and can be switched 
into another mode automatically with only a remote user-generated or an 
internal signal.
    Instantaneous average next-to-vend beverage temperature means the 
spatial average of all standard test packages in the next-to-vend 
beverages positions at a given time.
    Integrated average temperature means the average temperature of all 
standard test

[[Page 943]]

package measurements in the next-to-vend beverage positions taken over 
the duration of the test, expressed in degrees Fahrenheit ([deg]F).
    Low power mode means a state in which a beverage vending machine's 
lighting, refrigeration, and/or other energy-using systems are 
automatically adjusted (without user intervention) such that they 
consume less energy than they consume in an active vending environment.
    Lowest application product temperature means the lowest integrated 
average temperature a given basic model is capable of maintaining so as 
to comply with the temperature stabilization requirements specified in 
section 7.2.2.2 of ANSI/ASHRAE 32.1 (incorporated by reference, see 
Sec. 431.293).
    Refrigeration low power mode means a state in which a beverage 
vending machine's refrigeration system is in low power mode because of 
elevation of the temperature of the refrigerated compartment(s). To 
qualify as low power mode, the unit must satisfy the requirements 
described in section 2.3.2.1 of this appendix.
    2. Test Procedure.
    2.1. Test Conditions. The test conditions specified in section 6, 
``Test Conditions'' of ANSI/ASHRAE 32.1 (incorporated by reference, see

``Voltage and Frequency,'' of ANSI/ASHRAE 32.1, the voltage and 
frequency tolerances specified in section 6.1.a of ANSI/ASHRAE 32.1 also 
apply equivalently to section 6.1.b of ANSI/ASHRAE 32.1 for equipment 
with dual nameplate voltages.
    2.1.1. Average Beverage Temperature. The integrated average 
temperature measured during the test must be within 1 [deg]F of the value specified in Table B.1 of this 
appendix or the lowest application product temperature for models tested 
in accordance with paragraph 2.1.3 of this appendix. The measurement of 
integrated average temperature must begin after temperature 
stabilization has been achieve and continue for the following 24 
consecutive hours. All references to ``Table 1'' in ANSI/ASHRAE 32.1 
(incorporated by reference, see Sec. 431.293) shall instead be 
interpreted as references to Table B.1 of this appendix and all 
references to ``average beverage temperature'' in ANSI/ASHRAE 32.1 shall 
instead be interpreted as references to the integrated average 
temperature as defined in section 1.2 of this appendix, except as noted 
in section 2.1.1.1 of this appendix.
    2.1.1.1. Temperature Stabilization. Temperature stabilization shall 
be determined in accordance with section 7.2.2.2 of ANSI/ASHRAE 32.1 
(incorporated by reference Sec. 431.293), except that the reference to 
``average beverage temperature'' shall instead refer to the 
``instantaneous average next-to-vend beverage temperature,'' as defined 
in section 1.2 of this appendix, and the reference to ``Table 1'' shall 
instead refer to Table A.1 of this appendix. That is, temperature 
stabilization is considered to be achieved 24 hours after the 
instantaneous average next-to-vend beverage temperature reaches the 
specified value (see Table A.1) and energy consumption for two 
successive 6 hour periods are within 2 percent of each other.
    2.1.2. Ambient Test Conditions. The refrigerated bottled or canned

    (2) The right-most next-to-vend product location; and
    (3) For equipment with greater than or equal to five product 
locations on each shelf, either:
    (i) The next-to-vend product location in the center of the shelf 
(i.e., equidistant from the left-most and right-most next-to-vend 
product locations) if there are an odd number of next-to-vend products 
on the shelf or,
    (ii) The next-to-vend product location immediately to the right and 
the left of the center position if there are an even number of next-to-
vend products on the shelf.
    (b) For even-numbered shelves, when counting from the bottom shelf, 
standard test packages shall be places at either:

    2.2.1.2. Placement of Standard Test Packages for Equipment with 
Products Arranged Vertically. For refrigerated bottled or canned 
beverage vending machines with products arranged vertically (e.g., in 
stacks), place standard test packages in the refrigerated compartment(s) 
in each next-to-vend product location.
    2.2.1.3. Loading of Combination Vending Machines. For combination 
vending machines, the non-refrigerated compartment(s) must not be loaded 
with any standard products, test packages, or other vendible 
merchandise.
    2.2.1.4. Standard Products. The standard product shall be standard 
12-ounce aluminum beverage cans filled with a liquid with a density of 
1.0 grams per milliliter (g/mL) 0.1 g/mL at 36 
[deg]F. For product storage racks that are not capable of vending 12-
ounce cans, but are capable of vending 20-ounce bottles, the standard 
product shall be 20-ounce plastic bottles filled with a liquid with a 
density of 1.0 g/mL 0.1 g/mL at 36 [deg]F. For 
product storage racks that are not capable of vending 12-ounce cans or 
20-ounce bottles, the standard product shall be the packaging and 
contents specified by the manufacturer in product literature as the 
standard product (i.e., the specific merchandise the refrigerated 
bottled or canned beverage vending machine is designed to vend).
    2.2.1.5. Standard Test Packages. A standard test package is a 
standard product, as specified in 2.2.1.4 of this appendix, altered to 
include a temperature-measuring instrument at its center of mass.
    2.2.2. Sensor Placement. The integrated average temperature of next-
to-vend beverages shall be measured in standard test packages in the 
next-to-vend product locations specified in section 2.2.1.1 of this 
appendix. Do not run the thermocouple wire and other measurement 
apparatus through the dispensing door; the thermocouple wire and other 
measurement apparatus must be configured and sealed so as to minimize 
air flow between the interior refrigerated volume and the ambient room 
air. If a manufacturer chooses to employ a method other than routing 
thermocouple and sensor wires through the door gasket and ensuring the 
gasket is compressed around the wire to ensure a good seal, then it must 
maintain a record of the method used in the data underlying that basic 
model's certification pursuant to 10 CFR 429.71.
    2.2.3. Vending Mode Test Period. The vending mode test period begins 
after temperature stabilization has been achieved, as described in ANSI/
ASHRAE 32.1 section 7.2.2.2 (incorporated by reference, see Sec. 
431.293) and continues for 18 hours for equipment with an accessory low 
power mode or for 24 hours for

[[Page 946]]

equipment without an accessory low power mode. For the vending mode test 
period, equipment that has energy-saving features that cannot be 
disabled shall have those features set to the most energy-consuming 
settings, except for as specified in section 2.2.4 of this appendix. In 
addition, all energy management systems shall be disabled. Instead of 
testing pursuant to sections 7.1.1(d) and 7.2.2.4 of ANSI/ASHRAE 32.1, 
provide, if necessary, any physical stimuli or other input to the 
machine needed to prevent automatic activation of low power modes during 
the vending mode test period.
    2.2.4. Accessory Low Power Mode Test Period. For equipment with an 
accessory low power mode, the accessory low power mode may be engaged 
for 6 hours, beginning 18 hours after the temperature stabilization 
requirements established in section 7.2.2.2 of ANSI/ASHRAE 32.1 
(incorporated by reference, see Sec. 431.293) have been achieved, and 
continuing until the end of the 24-hour test period. During the 
accessory low power mode test, operate the refrigerated bottled or 
canned beverage vending machine with the lowest energy-consuming 
lighting and control settings that constitute an accessory low power 
mode. The specification and tolerances for integrated average 
temperature in Table B.1 of this appendix still apply, and any 
refrigeration low power mode must not be engaged. Instead of testing 
pursuant to sections 7.1.1(d) and 7.2.2.4 of ANSI/ASHRAE 32.1, provide, 
if necessary, any physical stimuli or other input to the machine needed 
to prevent automatic activation of refrigeration low power modes during 
the accessory low power mode test period.
    2.2.5. Accessories. Unless specified otherwise in this appendix, all 
standard components that would be used during normal operation of the 
basic model in the field and are necessary to provide sufficient 
functionality for cooling and vending products in field installations 
(i.e., product inventory, temperature management, product 
merchandising(including, e.g., lighting or signage), product selection, 
and product transport and delivery) shall be in place during testing and 
shall be set to the maximum energy-consuming setting if manually 
adjustable. Components not necessary for the inventory, temperature 
management, product merchandising (e.g., lighting or signage), product 
selection, or product transport and delivery shall be de-energized. If 
systems not required for the primary functionality of the machine as 
stated in this section cannot be de-energized without preventing the 
operation of the machine, then they shall be placed in the lowest energy 
consuming state Components with controls that are permanently 
operational and cannot be adjusted by the machine operator shall be 
operated in their normal setting and consistent with the requirements of 
2.2.3 and 2.2.4 of this appendix. The specific components and 
accessories listed in the subsequent sections shall be operated as 
stated during the test, except when controlled as part of a low power 
mode during the low power mode test period.
    2.2.5.1 Payment Mechanisms. Refrigerated bottled or canned beverage 
vending machines shall be tested with no payment mechanism in place, the 
payment mechanism in-place but de-energized, or the payment mechanism in 
place but set to the lowest energy consuming state, if it cannot be de-
energized. A default payment mechanism energy consumption value of 0.20 
kWh/day shall be added to the primary rated energy consumption per day, 
as noted in section 2.3 of this appendix.
    2.2.5.2. Internal Lighting. All lighting that is contained within or 
is part of the internal physical boundary of the refrigerated bottled or 
canned beverage vending machine, as established by the top, bottom, and 
side panels of the equipment, shall be placed in its maximum energy 
consuming state.
    2.2.5.3. External Customer Display Signs, Lights, and Digital 
Screens. All external customer display signs, lights, and digital 
screens that are independent from the refrigeration or vending 
performance of the refrigerated bottled or canned beverage vending 
machine must be disconnected, disabled, or otherwise de-energized for 
the duration of testing. Customer display signs, lighting, and digital 
screens that are integrated into the beverage vending machine cabinet or 
controls such that they cannot be de-energized without disabling the 
refrigeration or vending functions of the refrigerated bottled or canned 
beverage vending machine or modifying the circuitry must be placed in 
external accessory standby mode, if available, or their lowest energy-
consuming state. Digital displays that also serve a vending or money 
processing function must be placed in the lowest energy-consuming state 
that still allows the money processing feature to function.
    2.2.5.4. Anti-sweat or Other Electric Resistance Heaters. Anti-sweat 
or other electric resistance heaters must be operational during the 
entirety of the test procedure. Units with a user-selectable setting 
must have the heaters energized and set to the most energy-consumptive 
position. Units featuring an automatic, non-user-adjustable controller 
that turns on or off based on environmental conditions must be operating 
in the automatic state. Units that are not shipped with a controller 
from the point of manufacture, but are intended to be used with a 
controller, must be equipped with an appropriate controller when tested.
    2.2.5.5. Condensate Pan Heaters and Pumps. All electric resistance 
condensate heaters and condensate pumps must be installed and 
operational during the test. Prior to the start of the test, including 
the 24 hour period

[[Page 947]]

used to determine temperature stabilization prior to the start of the 
test period, as described in ANSI/ASHRAE 32.1 section 7.2.2.2 
(incorporated by reference, see Sec. 431.293), the condensate pan must 
be dry. For the duration of the test, including the 24 hour time period 
necessary for temperature stabilization, allow any condensate moisture 
generated to accumulate in the pan. Do not manually add or remove water 
from the condensate pan at any time during the test. Any automatic 
controls that initiate the operation of the condensate pan heater or 
pump based on water level or ambient conditions must be enabled and 
operated in the automatic setting.
    2.2.5.6. Illuminated Temperature Displays. All illuminated 
temperature displays must be energized and operated during the test the 
same way they would be energized and operated during normal field 
operation, as recommended in manufacturer product literature, including 
manuals.
    2.2.5.7. Condenser Filters. Remove any nonpermanent filters provided 
to prevent particulates from blocking a model's condenser coil.
    2.2.5.8. Security Covers. Remove any devices used to secure the 
model from theft or tampering.
    2.2.5.9. General Purpose Outlets. During the test, do not connect 
any external load to any general purpose outlets available on a unit.
    2.2.5.10. Crankcase Heaters and Other Electric Resistance Heaters 
for Cold Weather. Crankcase heaters and other electric resistance 
heaters for cold weather must be operational during the test. If a 
control system, such as a thermostat or electronic controller, is used 
to modulate the operation of the heater, it must be activated during the 
test and operated in accordance with the manufacturer's instructions.
    2.2.6. Sampling and Recording of Data. Record the data listed in 
section 7.2.2.3 of ANSI/ASHRAE 32.1 (incorporated by reference, see 
Sec. 431.293), at least every 1 minute. For the purpose of this 
section, ``average beverage temperature,'' listed in section 7.2.2.3 of 
ANSI/ASHRAE 32.1, means ``instantaneous average next-to-vend beverage 
temperature.''
    2.3. Determination of Daily Energy Consumption. In section 7.2.3.1 
of ANSI/ASHRAE 32.1 (incorporated by reference, see Sec. 431.293), the 
primary rated energy consumption per day (ED) shall be the energy 
measured during the vending mode test period and accessory low power 
mode test period, as specified in sections 2.2.3 and 2.2.4 of this 
appendix, as applicable.
    2.3.1. Energy Consumption of Payment Mechanisms. Calculate the sum 
of:
    (a) The default payment mechanism energy consumption value from 
section 2.2.5.1 and
    (b) The primary rated energy consumption per day (ED), in kWh, and 
determined in accordance with the calculation procedure in section 
7.2.3.1, ``Calculation of Daily Energy Consumption,'' of ANSI/ASHRAE 
32.1 (incorporated by reference, see Sec. 431.293).
    2.3.2. Refrigeration Low Power Mode. For refrigerated bottled or 
canned beverage vending machines with a refrigeration low power mode, 
multiply the value determined in section 2.3.1 of this appendix by 0.97 
to determine the daily energy consumption of the unit tested. For 
refrigerated bottled or canned beverage vending machines without a 
refrigeration low power mode, the value determined in section 2.3.1 is 
the daily energy consumption of the unit tested.
    2.3.2.1. Refrigeration Low Power Mode Validation Test Method. This 
test method is not required for the certification of refrigerated 
bottled or canned beverage vending machines. To verify the existence of 
a refrigeration low power mode, initiate the refrigeration low power 
mode in accordance with manufacturer instructions contained in product 
literature and manuals, after completion of the 6-hour low power mode 
test period. Continue recording all the data specified in section 2.2.6 
of this appendix until existence of a refrigeration low power mode has 
been confirmed or denied. The refrigerated bottled or canned beverage 
vending machine shall be deemed to have a refrigeration low power mode 
if either:
    (a) The following three requirements have been satisfied:
    (1) The instantaneous average next-to-vend beverage temperature must 
reach at least 4 [deg]F above the integrated average temperature or 
lowest application product temperature, as applicable, within 6 hours.
    (2) The instantaneous average next-to-vend beverage temperature must 
be maintained at least 4 [deg]F above the integrated average temperature 
or lowest application product temperature, as applicable, for at least 1 
hour.
    (3) After the instantaneous average next-to-vend beverage 
temperature is maintained at or above 4 [deg]F above the integrated 
average temperature or lowest application product temperature, as 
applicable, for at least 1 hour, the refrigerated beverage vending 
machine must return to the specified integrated average temperature or 
lowest application product temperature, as applicable, automatically 
without direct physical intervention.
    (b) Or, the compressor does not cycle on for the entire 6 hour 
period, in which case the instantaneous average beverage temperature 
does not have to reach 4 [deg]F above the integrated average temperature 
or lowest application product temperature, as applicable, but, the 
equipment must still automatically

[[Page 948]]

return to the integrated average temperature or lowest application 
product temperature, as applicable, after the 6 hour period without 
direct physical intervention.
    2.3.3. Calculations and Rounding. In all cases, the primary rated 
energy consumption per day (ED) must be calculated with raw 
measured values and the final result rounded to units of 0.01 kWh/day.
    3. Determination of Refrigeration Volume, Vendible Capacity, and 
Surface Area.
    3.1. Refrigerated Volume. Determine the ``refrigerated volume'' of 
refrigerated bottled or canned beverage vending machines in accordance 
with Appendix C, ``Measurement of Volume,'' of ANSI/ASHRAE 32.1 
(incorporated by reference, see Sec. 431.293). For combination vending 
machines, the ``refrigerated volume'' does not include any non-
refrigerated compartment(s).
    3.2. Vendible Capacity. Determine the ``vendible capacity'' of 
refrigerated bottled or canned beverage vending machines in accordance 
with the first paragraph of section 5, ``Vending Machine Capacity,'' of 
ANSI/ASHRAE 32.1 (incorporated by reference, see Sec. 431.293). For 
combination vending machines, the ``vendible capacity'' includes only 
the capacity of any portion of the refrigerated bottled or canned 
beverage vending machine that is refrigerated and does not include the 
capacity of the non-refrigerated compartment(s).
    3.3. Determination of Surface Area. Note: This section is not 
required for the certification of refrigerated bottled or canned 
beverage vending machines. Determine the surface area of each beverage 
vending machine as the length multiplied by the height of outermost 
surface of the beverage vending machine cabinet, measured from edge to 
edge excluding any legs or other protrusions that extend beyond the 
dimensions of the primary cabinet. Determine the transparent and non-
transparent areas on each side of a beverage vending machine as the 
total surface area of material that is transparent or is not 
transparent, respectively.

system or other demand-based control, PTO = 50 percent.
    (2) For anti-sweat heaters on coolers (if included): Without timers, 
control system or other demand-based control, PTO = 0 percent. With 
timers, control system or other demand-based control, PTO = 75 percent. 
For anti-sweat heaters on freezers (if included): Without timers,

          the interior index is represented by u = int and the exterior 
          index is represented by u = ext. If the electrical component 
          is both on the interior and exterior side of the display door 
          then u = int. For anti-sweat heaters sited anywhere in the 
          display door, 75 percent of the total power is be attributed 
          to u = int and 25 percent of the total power is attributed to

 Sec. Appendix B to Subpart R of Part 431--Uniform Test Method for the 
 Measurement of R-Value for Envelope Components of Walk-In Coolers and 
                            Walk-In Freezers

                                1.0 Scope

    This appendix covers the test requirements used to measure the R-
value of non-display panels and non-display doors of a walk-in cooler or 
walk-in freezer.

                             2.0 Definitions

    The definitions contained in Sec. 431.302 apply to this appendix.

                       3.0 Additional Definitions

    3.1 Edge region means a region of the panel that is wide enough to 
encompass any framing members. If the panel contains framing members 
(e.g., a wood frame) then the width of the edge region must be as wide 
as any framing member plus an additional 2 in.  
0.25 in.

[[Page 961]]

            4.0 Test Methods, Measurements, and Calculations

    4.1 The R value shall be the 1/K factor multiplied by the thickness 
of the panel.
    4.2 The K factor shall be based on ASTM C518 (incorporated by 
reference; see Sec. 431.303).
    4.3 For calculating the R value for freezers, the K factor of the 
foam at 20  1 degrees Fahrenheit (average foam 
temperature) shall be used. Test results from a test sample 1 0.1-inches in thickness may be used to determine the R 
value of panels with various foam thickness as long as the foam is of 
the same final chemical form.
    4.4 For calculating the R value for coolers, the K factor of the 
foam at 55  1 degrees Fahrenheit (average foam 
temperature) shall be used. Test results from a test sample 1  0.1-inches in thickness may be used to determine the R 
value of panels with various foam thickness as long as the foam is of 
the same final chemical form.
    4.5 Foam shall be tested after it is produced in its final chemical 
form. For foam produced inside of a panel (``foam-in-place''), ``final 
chemical form'' means the foam is cured as intended and ready for use as 
a finished panel. For foam produced as board stock (typically 
polystyrene), ``final chemical form'' means after extrusion and ready 
for assembly into a panel or after assembly into a panel. Foam from 
foam-in-place panels must not include any structural members or non-foam 
materials. Foam produced as board stock may be tested prior to its 
incorporation into a final panel. A test sample 1  
0.1-inches in thickness must be taken from the center of a panel and any 
protective skins or facers must be removed. A high-speed band-saw and a 
meat slicer are two types of recommended cutting tools. Hot wire cutters 
or other heated tools must not be used for cutting foam test samples. 
The two surfaces of the test sample that will contact the hot plate 
assemblies (as defined in ASTM C518 (incorporated by reference, see 
Sec. 431.303)) must both maintain 0.03 inches 
flatness tolerance and also maintain parallelism with respect to one 
another within 0.03 inches. Testing must be 
completed within 24 hours of samples being cut for testing.
    4.6 Internal non-foam member and/or edge regions shall not be 
considered when testing in accordance with ASTM C518 (incorporated by 
reference, see Sec. 431.303).
    4.7 For panels consisting of two or more layers of dissimilar 
insulating materials (excluding facers or protective skins), test each 
material as described in sections 4.1 through 4.6 of this appendix. For 
a panel with N layers of insulating material, the overall R-Value shall 
be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR28DE16.007


Where:

ki is the k factor of the ith material as measured by ASTM 
          C518, (incorporated by reference, see Sec. 431.303);
ti is the thickness of the ith material that appears in the 
          panel; and
N is the total number of material layers that appears in the panel.

Note: Superheat to be set according to equipment specification in equipment or installation manual. If no superheat specification is given, a default
  superheat value of 6.5 [deg]F shall be used. The superheat setting used in the test shall be reported as part of the standard rating.

             3.2. General Modifications: Methods of Testing

    When conducting testing in accordance with appendix C of AHRI 1250-
2009 (incorporated by reference; see Sec. 431.303), the following 
modifications must be made.
    3.2.1. In appendix C, section C3.1.6, any refrigerant temperature 
measurements upstream and downstream of the unit cooler may use sheathed 
sensors immersed in the flowing refrigerant instead of thermometer 
wells.
    3.2.2. It is not necessary to perform composition analysis of 
refrigerant (appendix C, section C3.3.6) or refrigerant oil 
concentration testing (appendix C, section C3.4.6).
    3.2.3. In appendix C, section C3.4.5, for verification of sub-
cooling downstream of mass flow meters, only the sight glass and a

[[Page 963]]

temperature sensor located on the tube surface under the insulation are 
required.
    3.2.4. In appendix C, section C3.5, regarding unit cooler fan power 
measurements, for a given motor winding configuration, the total power 
input shall be measured at the highest nameplate voltage. For three-
phase power, voltage imbalances shall be no more than 2 percent from 
phase to phase.
    3.2.5. In the test setup (appendix C, section C8.3), the liquid line 
and suction line shall be constructed of pipes of the manufacturer-
specified size. The pipe lines shall be insulated with a minimum total 
thermal resistance equivalent to \1/2\-inch thick insulation having a 
flat-surface R-Value of 3.7 ft\2\- [deg]F-hr/Btu per inch or greater. 
Flow meters need not be insulated but must not be in contact with the 
floor. The lengths of the connected liquid line and suction line shall 
be 25 feet  3 inches, not including the requisite 
flow meters, each. Of this length, no more than 15 feet shall be in the 
conditioned space. Where there are multiple branches of piping, the 
maximum length of piping applies to each branch individually as opposed 
to the total length of the piping.
    3.3. Matched systems, single-package dedicated systems, and unit 
coolers tested alone: Use the test method in AHRI 1250-2009 
(incorporated by reference; see Sec. 431.303), appendix C as the method 
of test for matched refrigeration systems, single-package dedicated 
systems, or unit coolers tested alone, with the following modifications:
    3.3.1. For unit coolers tested alone, use test procedures described 
in AHRI 1250-2009 (incorporated by reference; see Sec. 431.303) for 
testing unit coolers for use in mix-match system ratings, except that 
for the test conditions in Tables 15 and 16, use the Suction A 
saturation condition test points only. Also for unit coolers tested 
alone, use the calculations in section 7.9 to determine AWEF and net 
capacity described in AHRI 1250-2009 for unit coolers matched to 
parallel rack systems.
    3.3.2. In appendix C, section C.13, the version of AHRI Standard 420 
used for test methods, requirements, and procedures shall be AHRI 420-
2008 (incorporated by reference; see Sec. 431.303).
    3.3.3. Use appendix C, section C10 of AHRI 1250-2009 for off-cycle 
evaporator fan testing, with the exception that evaporator fan controls 
using periodic stir cycles shall be adjusted so that the greater of a 
50% duty cycle (rather than a 25% duty cycle) or the manufacturer 
default is used for measuring off-cycle fan energy. For adjustable-speed 
controls, the greater of 50% fan speed (rather than 25% fan speed) or 
the manufacturer's default fan speed shall be used for measuring off-
cycle fan energy. Also, a two-speed or multi-speed fan control may be 
used as the qualifying evaporator fan control. For such a control, a fan 
speed no less than 50% of the speed used in the maximum capacity tests 
shall be used for measuring off-cycle fan energy.
    3.3.4. Use appendix C, section C11 of AHRI 1250-2009 (incorporated 
by reference, see Sec. 431.303) for defrost testing. The Frost Load 
Condition Defrost Test (C11.1.1) is optional.
    3.3.4.1. If the frost load condition defrost test is performed:
    3.3.4.1.1 Operate the unit cooler at the dry coil conditions as 
specified in appendix C, section C11.1 to obtain dry coil defrost 
energy, DFd, in W-h.
    3.3.4.1.2 Operate the unit cooler at the frost load conditions as 
specified in appendix C, sections C11.1 and C11.1.1 to obtain frosted 
coil defrost energy, DFf, in W-h.
    3.3.4.1.3 The number of defrosts per day, NDF, shall be 
calculated from the time interval between successive defrosts from the 
start of one defrost to the start of the next defrost at the frost load 
conditions.
    3.3.4.1.4 Use appendix C, equations C13 and C14 in section C11.3 to 
calculate, respectively, the daily average defrost energy, DF, in W-h 
and the daily contribution of the load attributed to defrost 
QDF in Btu.
    3.3.4.1.5 The defrost adequacy requirements in appendix C, section 
C11.3 shall apply.
    3.3.4.2 If the frost load test is not performed:
    3.3.4.2.1 Operate the unit cooler at the dry coil conditions as 
specified in appendix C, section C11.1 to obtain dry coil defrost 
energy, DFd, in W-h.
    3.3.4.2.2 The frost load defrost energy, DFf, in W-h 
shall be equal to 1.05 multiplied by the dry coil energy consumption, 
DFd, measured using the dry coil condition test in appendix 
C, section C11.1.
    3.3.4.2.3 The number of defrosts per day NDF used in 
subsequent calculations shall be 4.
    3.3.4.2.4 Use appendix C, equation C13 in section C11.3 to calculate 
the daily average defrost energy, DF, in W-h.
    3.3.4.2.5 The daily contribution of the load attributed to defrost 
QDF in Btu shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR28DE16.008



[[Page 964]]


Where:

DFd = the defrost energy, in W-h, measured at the dry coil 
          condition

    3.3.5. If a unit has adaptive defrost, use appendix C, section C11.2 
of AHRI 1250-2009 as follows:
    3.3.5.1. When testing to certify to the energy conservation 
standards in Sec. 431.306, do not perform the optional test for 
adaptive or demand defrost in appendix C, section C11.2.
    3.3.5.2. When determining the represented value of the calculated 
benefit for the inclusion of adaptive defrost, conduct the optional test 
for adaptive or demand defrost in appendix C, section C11.2 to establish 
the maximum time interval allowed between dry coil defrosts. If this 
time is greater than 24 hours, set its value to 24 hours. Then, 
calculate NDF (the number of defrosts per day) by averaging 
the time in hours between successive defrosts for the dry coil condition 
with the time in hours between successive defrosts for the frosted coil 
condition, and dividing 24 by this average time. (The time between 
successive defrosts for the frosted coil condition is found as specified 
in section 3.3.4 of this appendix C of AHRI 1250-2009: That is, if the 
optional frosted coil test was performed, the time between successive 
defrosts for the frosted coil condition is found by performing the 
frosted coil test as specified in section 3.3.4.1 of this appendix; and 
if the optional frosted coil test was not performed, the time between 
successive defrosts for the frosted coil condition shall be set to 4 as 
specified in section 3.3.4.2. of this appendix) Use this new value of 
NDF in subsequent calculations.
    3.3.6. For matched refrigeration systems and single-package 
dedicated systems, calculate the AWEF using the calculations in AHRI 
1250-2009 (incorporated by reference; see Sec. 431.303), section 7.4, 
7.5, 7.6, or 7.7, as applicable.
    3.3.7. For unit coolers tested alone, calculate the AWEF and net 
capacity using the calculations in AHRI 1250-2009, (incorporated by 
reference; see Sec. 431.303), section 7.9. If the unit cooler has 
variable-speed evaporator fans that vary fan speed in response to load, 
then:
    3.3.7.1. When testing to certify compliance with the energy 
conservation standards in Sec. 431.306, fans shall operate at full 
speed during on-cycle operation. Do not conduct the calculations in AHRI 
1250-2009, section 7.9.3. Instead, use AHRI 1250-2009, section 7.9.2 to 
determine the system's AWEF.
    3.3.7.2. When calculating the benefit for the inclusion of variable-
speed evaporator fans that modulate fan speed in response to load for 
the purposes of making representations of efficiency, use AHRI 1250-
2009, section 7.9.3 to determine the system AWEF.

3.4. Dedicated condensing units that are not matched for testing and are 
                  not single-package dedicated systems

    3.4.1. Refer to appendix C, section C.12 of AHRI 1250-2009 
(incorporated by reference; see Sec. 431.303), for the method of test 
for dedicated condensing units. The version of ASHRAE Standard 23 used 
for test methods, requirements, and procedures shall be ANSI/ASHRAE 
Standard 23.1-2010 (incorporated by reference; see Sec. 431.303). When 
applying this test method, use the applicable test method modifications 
listed in sections 3.1 and 3.2 of this appendix. For the test conditions 
in AHRI 1250-2009, Tables 11, 12, 13, and 14, use the Suction A 
condition test points only.
    3.4.2. Calculate the AWEF and net capacity for dedicated condensing 
units using the calculations in AHRI 1250-2009 (incorporated by 
reference; see Sec. 431.303) section 7.8. Use the following 
modifications to the calculations in lieu of unit cooler test data:
    3.4.2.1. For calculating enthalpy leaving the unit cooler to 
calculate gross capacity, (a) The saturated refrigerant temperature (dew 
point) at the unit cooler coil exit, Tevap, shall be 25 
[deg]F for medium-temperature systems (coolers) and -20 [deg]F for low-
temperature systems (freezers), and (b) the refrigerant temperature at 
the unit cooler exit shall be 35 [deg]F for medium-temperature systems 
(coolers) and -14 [deg]F for low-temperature systems (freezers). For 
calculating gross capacity, the measured enthalpy at the condensing unit 
exit shall be used as the enthalpy entering the unit cooler.
    3.4.2.2. The on-cycle evaporator fan power in watts, 
EFcomp,on, shall be calculated as follows:
    For medium-temperature systems (coolers), EFcomp,on = 
0.013 x qmix,cd
    For low-temperature systems (freezers), EFcomp,on = 0.016 
x qmix,cd

Where:

qmix,cd is the gross cooling capacity of the system in Btu/h, 
          found by a single test at the Capacity A, Suction A condition 
          for outdoor units and the Suction A condition for indoor 
          units.

    3.4.2.3. The off-cycle evaporator fan power in watts, 
EFcomp,off, shall be calculated as follows:

    EFcomp,off = 0.2 x EFcomp,on

Where:

EF comp,on is the on-cycle evaporator fan power in watts.

    3.4.2.4. The daily defrost energy use in watt-hours, DF, shall be 
calculated as follows:
    For medium-temperature systems (coolers), DF = 0
    For low-temperature systems (freezers), DF = 8.5 x 10-3 x 
qmix,cd\1.27\ x NDF


[[Page 965]]


Where:

qmix,cd is the gross cooling capacity of the system in Btu/h, 
          found by a single test at the Capacity A, Suction A condition 
          for outdoor units and the Suction A condition for indoor 
          units, and
NDF is the number of defrosts per day, equal to 4.

    3.4.2.5. The daily defrost heat load contribution in Btu, 
QDF, shall be calculated as follows:
    For medium-temperature systems (coolers), QDF = 0
    For low-temperature systems (freezers), QDF = 0.95 x DF x 
3.412

Where:

DF is the daily defrost energy use in watt-hours.

                3.5 Hot Gas Defrost Refrigeration Systems

    For all hot gas defrost refrigeration systems, remove the hot gas 
defrost mechanical components and disconnect all such components from 
electrical power.
    3.5.1 Hot Gas Defrost Dedicated Condensing Units Tested Alone: Test 
these units as described in section 3.4 of this appendix for electric 
defrost dedicated condensing units that are not matched for testing and 
are not single-package dedicated systems.
    3.5.2 Hot Gas Defrost Matched Systems, Single-package Dedicated 
Systems, and Unit Coolers Tested Alone: Test these units as described in 
section 3.3 of this appendix for electric defrost matched systems, 
single-package dedicated systems, and unit coolers tested alone, but do 
not conduct defrost tests as described in sections 3.3.4 and 3.3.5 of 
this appendix. Calculate daily defrost energy use as described in 
section 3.4.2.4 of this appendix. Calculate daily defrost heat 
contribution as described in section 3.4.2.5 of this appendix.

section 4.4.2 of ANSI C82.6, and stabilization shall be reached when the 
lamp's electrical characteristics vary by no more than 3-percent in 
three consecutive 10- to 15-minute intervals measured after the minimum 
burning time of 30 minutes. After the stabilization process has begun, 
the lamp shall not be moved or repositioned until after the testing is 
complete. In order to avoid heating up the test ballast during lamp 
stabilization, which could cause resistance changes and result in 
unrepeatable data, it is necessary to warm up the lamp on a standby 
ballast. This standby ballast should be a commercial ballast of a type 
similar to the test ballast in order to be able to switch a stabilized 
lamp to the test ballast without extinguishing the lamp. Fast-acting or 
make-before-break switches are recommended to prevent the lamps from 
extinguishing during switchover.
    (ii) Alternative Stabilization Method. In cases where switching 
without extinguishing the lamp is impossible or for low-frequency 
electronic ballasts, the following alternative stabilization

[[Page 968]]

method shall be used. The lamp characteristics are determined using a 
reference ballast and recorded for future comparison. The same lamp is 
to be driven by the ballast under test until the ballast reaches 
operational stability. Operational stability is defined by three 
consecutive measurements, 5 minutes apart, of the lamp power where the 
three readings are within 2.5 percent. The electrical measurements are 
to be taken within 5 minutes after conclusion of the stabilization 
period.
    (iii) Input Voltage for Tests. For ballasts designed to operate 
lamps rated less than 150 W that have 120 V as an available input 
voltage, testing shall be performed at 120 V. For ballasts designed to 
operate lamps rated less than 150 W that do not have 120 V as an 
available voltage, testing shall be performed at the highest available 
input voltage. For ballasts designed to operate lamps rated greater than 
or equal to 150 W that have 277 V as an available input voltage, testing 
shall be conducted at 277 V. For ballasts designed to operate lamps 
rated greater than or equal to 150 W that do not have 277 V as an 
available input voltage, testing shall be conducted at the highest 
available input voltage.
    (2) Test Measurement. The ballast input power and lamp output power 
during operating conditions shall be measured in accordance with the 
methods specified in section 6.0, ``Ballast Measurements (Multiple-
Supply Type Ballasts)'' of the ANSI C82.6 (incorporated by reference; 
see Sec. 431.323).
    (3) Efficiency Calculation. The measured lamp output power shall be 
divided by the measured ballast input power to determine the percent 
efficiency of the ballast under test to three significant figures.
    (i) A fractional number at or above the midpoint between two 
consecutive decimal places shall be rounded up to the higher of the two 
decimal places; or
    (ii) A fractional number below the midpoint between two consecutive 
decimal places shall be rounded down to the lower of the two decimal 
places.
    (c) Testing and Calculations-Standby Mode. The measurement of 
standby mode need not be performed to determine compliance with energy 
conservation standards for metal halide lamp fixtures at this time. The 
above statement will be removed as part of the rulemaking to amend the 
energy conservation standards for metal halide lamp fixtures to account 
for standby mode energy consumption, and the following shall apply on 
the compliance date for such requirements. However, all representations 
related to standby mode energy consumption of these products made after 
September 7, 2010, must be based upon results generated under this test 
procedure.
    (1) Test Conditions. (i) The power supply and ballast test 
conditions with the exception of input voltage shall all conform to the 
requirements specified in section 4.0, ``General Conditions for 
Electrical Performance Tests,'' of the ANSI C82.6 (incorporated by 
reference; see Sec. 431.323). Ambient temperatures for the testing 
period shall be maintained at 25 [deg]C 5 [deg]C. 
Send a signal to the ballast instructing it to have zero light output 
using the appropriate ballast communication protocol or system for the 
ballast being tested.
    (ii) Input Voltage for Tests. For ballasts designed to operate lamps 
rated less than 150 W that have 120 V as an available input voltage, 
ballasts are to be tested at 120 V. For ballasts designed to operate 
lamps rated less than 150 W that do not have 120 V as an available 
voltage, ballasts are to be tested at the highest available input 
voltage. For ballasts designed to operate lamps rated greater than or 
equal to 150 W that have 277 V as an available input voltage, ballasts 
are to be tested at 277 V. For ballasts designed to operate lamps rated 
greater than or equal to 150 W that do not have 277 V as an available 
input voltage, ballasts are to be tested at the highest available input 
voltage.
    (2) Measurement of Main Input Power. Measure the input power (watts) 
to the ballast in accordance with the methods specified in section 6.0, 
``Ballast Measurements (Multiple-Supply Type Ballasts)'' of the ANSI 
C82.6 (incorporated by reference; see Sec. 431.323).
    (3) Measurement of Control Signal Power. The power from the control 
signal path is measured using all applicable methods described below:
    (i) DC Control Signal. Measure the DC control signal voltage, using 
a

[[Page 969]]

voltmeter (V), and current, using an ammeter (A) connected to the 
ballast in accordance with the circuit shown in Figure 1. The DC control 
signal power is calculated by multiplying the DC control signal voltage 
by the DC control signal current.
[GRAPHIC] [TIFF OMITTED] TR09MR10.005

    (ii) AC Control Signal. Measure the AC control signal power (watts), 
using a wattmeter capable of indicating true RMS power in watts (W), 
connected to the ballast in accordance with the circuit shown in Figure 
2.
[GRAPHIC] [TIFF OMITTED] TR09MR10.006

    (iii) Power Line Carrier (PLC) Control Signal. Measure the PLC 
control signal power (watts), using a wattmeter capable of indicating 
true RMS power in watts (W) connected to the ballast in accordance with 
the circuit shown in Figure 3. The wattmeter must have a frequency 
response that is at least 10 times higher than the PLC being measured to 
measure the PLC signal correctly. The wattmeter must also be high-pass 
filtered to filter out power at 60 Hz.

   Sec. Appendix A to Subpart T of Part 431--Uniform Test Method for 
                         Certain Air Compressors

    Note: Starting on July 3, 2017, any representations made with 
respect to the energy use or efficiency of compressors subject to 
testing pursuant to 10 CFR 431.344 must be made in accordance with the 
results of testing pursuant to this appendix.

      I. Measurements, Test Conditions, and Equipment Configuration

                        A. Measurement Equipment

    A.1. For the purposes of measuring air compressor performance, the 
equipment necessary to measure volume flow rate, inlet and discharge 
pressure, temperature, condensate, and packaged compressor power input 
must comply with the equipment and accuracy requirements specified in 
ISO 1217:2009(E) sections 5.2, 5.3, 5.4, 5.6, 5.9, and Annex C, sections 
C.2.3 and C.2.4 (incorporated by reference, see Sec. 431.343).
    A.2. Electrical measurement equipment must be capable of measuring 
true root mean square (RMS) current, true RMS voltage, and real power up 
to the 40th harmonic of fundamental supply source frequency.
    A.3. Any instruments used to measure a particular parameter 
specified in paragraph (A.1.) must have a combined accuracy of 2.0 percent of the measured value at the fundamental 
supply source frequency, where combined accuracy is the square root of 
the sum of the squares of individual instrument accuracies.
    A.4. Any instruments used to directly measure the density of air 
must have an accuracy of 1.0 percent of the 
measured value.
    A.5. Any pressure measurement equipment used in a calculation of 
another variable (e.g., actual volume flow rate) must also meet all 
accuracy and measurement requirements of section 5.2 of ISO 1217:2009(E) 
(incorporated by reference, see Sec. 431.343).
    A.6. Any temperature measurement equipment used in a calculation of

accuracy and measurement requirements of section 5.3 of ISO 1217:2009(E) 
(incorporated by reference, see Sec. 431.343).
    A.7. Where ISO 1217:2009(E) refers to ``corrected volume flow 
rate,'' the term is deemed synonymous with the term ``actual volume flow 
rate,'' as defined in section 3.4.1 of ISO 1217:2009(E) (incorporated by 
reference, see Sec. 431.343).

         B. Test Conditions and Configuration of Unit Under Test

testing in accordance with the test conditions, unit configuration, and 
specifications of ISO 1217:2009(E), Section 6.2 paragraphs (g) and (h) 
and Annex C, sections C.1.1, C.2.2, C.2.3, C.2.4, C.4.1, C.4.2.1, 
C.4.2.3, and C.4.3.2 (incorporated by reference, see Sec. 431.343).
    B.2. The power supply must:
    (1) Maintain the voltage greater than or equal to 95 percent and 
less than or equal to 110 percent of the rated value of the motor,
    (2) Maintain the frequency within 5 percent of 
the rated value of the motor,
    (3) Maintain the voltage unbalance of the power supply within 3 percent of the rated values of the motor, and
    (4) Maintain total harmonic distortion below 12 percent throughout 
the test.
    B.3. Ambient Conditions. The ambient air temperature must be greater 
than or equal to 68 [deg]F and less than or equal to 90 [deg]F for the 
duration of testing. There are no ambient condition requirements for 
inlet pressure or relative humidity.
    B.4. All equipment indicated in Table 1 of this appendix must be 
present and installed for all tests specified in this appendix. If the 
compressor is distributed in commerce without an item from Table 1 of 
this appendix, the manufacturer must provide an appropriate item to be 
installed for the test. Additional ancillary equipment may be installed 
for the test, if distributed in commerce with the compressor, but this 
additional ancillary equipment is not required. If any of the equipment 
listed in Table 2 of this appendix is distributed in commerce with units 
of the compressor basic model, it must be present and installed for all

  II. Determination of Package Isentropic Efficiency, Package Specific 
        Power, and Pressure Ratio at Full-Load Operating Pressure

                     A. Data Collection and Analysis

    A.1. Stabilization. Record data at each load point under steady-
state conditions. Steady-state conditions are achieved when a set of two 
consecutive readings taken at least 10 seconds apart and no more than 60 
seconds apart are within the maximum permissible fluctuation from the 
average (of the two consecutive readings), as specified in Table 1 of 
ISO 1217:2009(E) (incorporated by reference, see Sec. 431.343) for--
    (1) Discharge pressure;
    (2) Temperature at the nozzle or orifice plate, measured per section 
5.3 of ISO 1217:2009(E) (incorporated by reference, see Sec. 431.343); 
and
    (3) Differential pressure over the nozzle or orifice plate, measured 
per section 5.2 of ISO 1217:2009(E) (incorporated by reference, see 
Sec. 431.343).
    A.2. Data Sampling and Frequency. At each load point, record a 
minimum set of 16 unique readings, collected over a minimum time of 15 
minutes. Each consecutive reading

[[Page 976]]

must be no more than 60 seconds apart, and not less than 10 seconds 
apart. All readings at each load point must be within the maximum 
permissible fluctuation from average specified in Table 1 of ISO 
1217:2009(E) (incorporated by reference, see Sec. 431.343) for--
    (1) Discharge pressure;
    (2) Temperature at the nozzle or orifice plate, measured per section 
5.3 of ISO 1217:2009(E) (incorporated by reference, see Sec. 431.343); 
and
    (3) Differential pressure over the nozzle or orifice plate, measured 
per section 5.2 of ISO 1217:2009(E) (incorporated by reference, see 
Sec. 431.343).
    If one or more readings do not meet the requirements, then all 
previous readings must be disregarded and a new set of at least 16 new 
unique readings must be collected over a minimum time of 15 minutes. 
Average the readings to determine the value of each parameter to be used 
in subsequent calculations.
    A.3. Calculations and Rounding. Perform all calculations using raw 
measured values. Round the final result for package isentropic 
efficiency to the thousandth (i.e., 0.001), for package specific power 
in kilowatts per 100 cubic feet per minute to the nearest hundredth 
(i.e., 0.01), for pressure ratio at full-load operating pressure to the 
nearest tenth (i.e., 0.1), for full-load actual volume flow rate in 
cubic feet per minute to the nearest tenth (i.e., 0.1), and for full-
load operating pressure in pounds per square inch gauge (psig) to the 
nearest integer (i.e., 1). All terms and quantities refer to values 
determined in accordance with the procedures set forth in this appendix 
for the tested unit.

          variable use a value of 100 kPa for contractual inlet 
          pressure; and
PPR,100 = packaged compressor power input reading at 
          full-load operating pressure and full-load actual volume flow 
          rate measured in section II.C.1 of this appendix (W).

of full-load actual volume flow rate, as determined in section II.D.3.1 
of this appendix. For Preal, use the real packaged compressor

          III.C.4 of this appendix (Pa gauge).

III. Method to Determine Maximum Full-Flow Operating Pressure, Full-Load 
        Operating Pressure, and Full-Load Actual Volume Flow Rate

                          A. Principal Strategy

    The principal strategy of this method is to incrementally increase 
discharge pressure by 2 psig relative to a starting point, and identify 
the maximum full-flow operating pressure at which the compressor is 
capable of operating. The maximum discharge pressure achieved is the 
maximum full-flow operating pressure. The full-load operating pressure 
and full-load actual volume flow rate are determined based on the 
maximum full-flow operating pressure.

                        B. Pre-test Instructions

                               B.1. Safety

    For the method presented in section III.C.1 of this appendix, only 
test discharge pressure within the safe operating range of the 
compressor, as specified by the manufacturer in the installation and 
operation manual shipped with the unit. Make no changes to safety limits 
or equipment. Do not violate any manufacturer-provided motor operational 
guidelines for normal use, including any restriction on instantaneous 
and continuous input power draw and output shaft power (e.g., electrical 
rating and service factor limits).

                  B.2. Adjustment of Discharge Pressure

    B.2.1. If the air compressor is not equipped, as distributed in 
commerce by the manufacturer, with any mechanism to adjust the maximum 
discharge pressure output limit, proceed to section III.B.3 of this 
appendix.
    B.2.2. If the air compressor is equipped, as distributed in commerce 
by the manufacturer, with any mechanism to adjust the maximum discharge 
pressure output limit, then adjust this mechanism to the maximum

[[Page 979]]

pressure allowed, according to the manufacturer's operating instructions 
for these mechanisms. Mechanisms to adjust discharge pressure may 
include, but are not limited to, onboard digital or analog controls, and 
user-adjustable inlet valves.

                            B.3. Driver speed

    If the unit under test is a variable-speed compressor, maintain 
maximum driver speed throughout the test. If the unit under test is a 
fixed-speed compressor with a multi-speed driver, maintain driver speed 
at the maximum speed throughout the test.

                    B.4. Measurements and Tolerances

                            B.4.1. Recording

    Record data by electronic means such that the requirements of 
section B.4.5 of section III of this appendix are met.

                        B.4.2. Discharge Pressure

    Measure discharge pressure in accordance with section 5.2 of ISO 
1217:2009(E) (incorporated by reference, see Sec. 431.343). Express 
compressor discharge pressure in psig in reference to ambient 
conditions, and record it to the nearest integer. Specify targeted 
discharge pressure points in integer values only. The maximum allowable 
measured deviation from the targeted discharge pressure at each tested 
point is 1 psig.

                     B.4.3. Actual Volume Flow Rate

    Measure actual volume flow rate in accordance with section C.4.2.1 
of Annex C of ISO 1217:2009(E) (incorporated by reference, see Sec. 
431.343) (where it is called ``corrected volume flow rate'') with no 
corrections made for shaft speed. Express compressor actual volume flow 
rate in cubic feet per minute at inlet conditions (cfm).

                          B.4.4. Stabilization

    Record data at each tested load point under steady-state conditions, 
as determined in section II.A.1 of this appendix.

                   B.4.5. Data Sampling and Frequency

    At each load point, record a set of at least of two readings, 
collected at a minimum of 10 seconds apart. All readings at each load 
point must be within the maximum permissible fluctuation from the 
average (of the two consecutive readings), as specified in II.A.2 of 
this appendix. Average the measurements to determine the value of each 
parameter to be used in subsequent calculations.

                   B.5. Adjusting System Backpressure

    Set up the unit under test so that backpressure on the unit can be 
adjusted (e.g., by valves) incrementally, causing the measured discharge 
pressure to change, until the compressor is in an unloaded condition.

                         B.6. Unloaded Condition

    A unit is considered to be in an unloaded condition if capacity 
controls on the unit automatically reduce the actual volume flow rate 
from the compressor (e.g., shutting the motor off, or unloading by 
adjusting valves).

                          C. Test Instructions

    C.1. Adjust the backpressure of the system so the measured discharge 
pressure is 90 percent of the expected maximum full-flow operating 
pressure, rounded to the nearest integer, in psig. If the expected 
maximum full-flow operating pressure is not known, then adjust the 
backpressure of the system so that the measured discharge pressure is 65 
psig. Allow the unit to remain at this setting for 15 minutes to allow 
the unit to thermally stabilize. Then measure and record discharge 
pressure and actual volume flow rate at the starting pressure.
    C.2. Adjust the backpressure of the system to increase the discharge 
pressure by 2 psig from the previous value, allow the unit to remain at 
this setting for a minimum of 2 minutes, and proceed to section III.C.3 
of this appendix.
    C.3. If the unit is now in an unloaded condition, end the test and 
proceed to section III.C.4 of this appendix. If the unit is not in an 
unloaded condition, measure discharge pressure and actual volume flow 
rate, and repeat section III.C.2 of this appendix.
    C.4. Of the discharge pressures recorded under stabilized conditions 
in sections III.C.1 through III.C.3 of this appendix, identify the 
largest. This is the maximum full-flow operating pressure. Determine the 
full-load operating pressure as a self-declared value greater than or 
equal to the lesser of (A) 90 percent of the maximum full-flow operating 
pressure, or (B) 10 psig less than the maximum full-flow operating 
pressure.
    C.5. The full-load actual volume flow rate is the actual volume flow 
rate measured at the full-load operating pressure. If the self-declared 
full-load operating pressure falls on a previously tested value of 
discharge pressure, then use the previously measured actual volume flow 
rate as the full-load actual volume flow rate. If the self-declared 
full-load operating pressure does not fall on a previously tested value 
of discharge pressure, then adjust the backpressure of the system to the 
self-declared full-load operating pressure and allow the unit to remain 
at this setting for a minimum of 2 minutes. The measured actual volume 
flow rate at this setting is the full-load actual volume flow rate.

Sec. 431.383  Enforcement process for electric motors.

    (a) Test notice. Upon receiving information in writing, concerning 
the energy performance of a particular electric motor sold by a 
particular manufacturer or private labeler, which indicates that the 
electric motor may not be in compliance with the applicable energy 
efficiency standard, or upon undertaking to ascertain the accuracy of 
the efficiency rating on the nameplate or in marketing materials for an 
electric motor, disclosed pursuant to subpart B of this part, the 
Secretary may conduct testing of that electric motor under this subpart 
by means of a test notice addressed to the manufacturer

[[Page 981]]

in accordance with the following requirements:
    (1) The test notice procedure will only be followed after the 
Secretary or his/her designated representative has examined the 
underlying test data (or, where appropriate, data as to use of an 
alternative efficiency determination method) provided by the 
manufacturer and after the manufacturer has been offered the opportunity 
to meet with the Department to verify, as applicable, compliance with 
the applicable efficiency standard, or the accuracy of labeling 
information, or both. In addition, where compliance of a basic model was 
certified based on an AEDM, the Department shall have the discretion to 
pursue the provisions of Sec. 431.17(a)(4)(iii) prior to invoking the 
test notice procedure. A representative designated by the Secretary 
shall be permitted to observe any re-verification procedures undertaken 
pursuant to this subpart, and to inspect the results of such 
reverification.
    (2) The test notice will be signed by the Secretary or his/her 
designee. The test notice will be mailed or delivered by the Department 
to the plant manager or other responsible official, as designated by the 
manufacturer.
    (3) The test notice will specify the model or basic model to be 
selected for testing, the method of selecting the test sample, the date 
and time at which testing shall be initiated, the date by which testing 
is scheduled to be completed and the facility at which testing will be 
conducted. The test notice may also provide for situations in which the 
specified basic model is unavailable for testing, and may include 
alternative basic models.
    (4) The Secretary may require in the test notice that the 
manufacturer of an electric motor shall ship at his expense a reasonable 
number of units of a basic model specified in such test notice to a 
testing laboratory designated by the Secretary. The number of units of a 
basic model specified in a test notice shall not exceed 20.
    (5) Within five working days of the time the units are selected, the 
manufacturer shall ship the specified test units of a basic model to the 
testing laboratory.
    (b) Testing laboratory. Whenever the Department conducts enforcement 
testing at a designated laboratory in accordance with a test notice 
under this section, the resulting test data shall constitute official 
test data for that basic model. Such test data will be used by the 
Department to make a determination of compliance or noncompliance if a 
sufficient number of tests have been conducted to satisfy the 
requirements of appendix A of this subpart.
    (c) Sampling. The determination that a manufacturer's basic model 
complies with its labeled efficiency, or the applicable energy 
efficiency standard, shall be based on the testing conducted in 
accordance with the statistical sampling procedures set forth in 
appendix A of this subpart and the test procedures set forth in appendix 
B to subpart B of this part.
    (d) Test unit selection. A Department inspector shall select a 
batch, a batch sample, and test units from the batch sample in 
accordance with the provisions of this paragraph and the conditions 
specified in the test notice.
    (1) The batch may be subdivided by the Department utilizing criteria 
specified in the test notice.
    (2) A batch sample of up to 20 units will then be randomly selected 
from one or more subdivided groups within the batch. The manufacturer 
shall keep on hand all units in the batch sample until such time as the 
basic model is determined to be in compliance or non-compliance.
    (3) Individual test units comprising the test sample shall be 
randomly selected from the batch sample.
    (4) All random selection shall be achieved by sequentially numbering 
all of the units in a batch sample and then using a table of random 
numbers to select the units to be tested.
    (e) Test unit preparation. (1) Prior to and during the testing, a 
test unit selected in accordance with paragraph (d) of this section 
shall not be prepared, modified, or adjusted in any manner unless such 
preparation, modification, or adjustment is allowed by the applicable 
Department of Energy test procedure. One test shall be conducted for 
each test unit in accordance with the

[[Page 982]]

applicable test procedures prescribed in appendix B to subpart B of this 
part.
    (2) No quality control, testing, or assembly procedures shall be 
performed on a test unit, or any parts and sub-assemblies thereof, that 
is not performed during the production and assembly of all other units 
included in the basic model.
    (3) A test unit shall be considered defective if such unit is 
inoperative or is found to be in noncompliance due to failure of the 
unit to operate according to the manufacturer's design and operating 
instructions. Defective units, including those damaged due to shipping 
or handling, shall be reported immediately to the Department. The 
Department shall authorize testing of an additional unit on a case-by-
case basis.
    (4)(i) Non-standard endshields or flanges. For purposes of DOE-
initiated testing of electric motors with non-standard endshields or 
flanges, the Department will have the discretion to determine whether 
the lab should test a general purpose electric motor of equivalent 
electrical design and enclosure rather than replacing the nonstandard 
flange or endshield.
    (ii) Partial electric motors. For purposes of DOE-initiated testing, 
the Department has the discretion to determine whether the lab should 
test a general purpose electric motor of equivalent electrical design 
and enclosure rather than machining and attaching an endshield.
    (f) Testing at manufacturer's option. (1) If a manufacturer's basic 
model is determined to be in noncompliance with the applicable energy 
performance standard at the conclusion of Department testing in 
accordance with the sampling plan specified in appendix A of this 
subpart, the manufacturer may request that the Department conduct 
additional testing of the basic model according to procedures set forth 
in appendix A of this subpart.
    (2) All units tested under this paragraph shall be selected and 
tested in accordance with the provisions given in paragraphs (a) through 
(e) of this section.
    (3) The manufacturer shall bear the cost of all testing conducted 
under this paragraph.
    (4) The manufacturer shall cease distribution of the basic model 
tested under the provisions of this paragraph from the time the 
manufacturer elects to exercise the option provided in this paragraph 
until the basic model is determined to be in compliance. The Department 
may seek civil penalties for all units distributed during such period.
    (5) If the additional testing results in a determination of 
compliance, a notice of allowance to resume distribution shall be issued 
by the Department.

Sec. 431.384  [Reserved]



Sec. 431.385  Cessation of distribution of a basic model of an
electric motor.

    (a) In the event that a model of an electric motor is determined 
non-compliant by the Department in accordance with Sec. 431.192 or if a 
manufacturer or private labeler determines a model of an electric motor 
to be in noncompliance, then the manufacturer or private labeler shall:
    (1) Immediately cease distribution in commerce of the basic model.
    (2) Give immediate written notification of the determination of 
noncompliance, to all persons to whom the manufacturer has distributed 
units of the basic model manufactured since the date of the last 
determination of compliance.
    (3) Pursuant to a request made by the Secretary, provide the 
Department within 30 days of the request, records, reports, and other 
documentation pertaining to the acquisition, ordering, storage, 
shipment, or sale of a basic model determined to be in noncompliance.
    (4) The manufacturer may modify the non-compliant basic model in 
such manner as to make it comply with the applicable performance 
standard. Such modified basic model shall then be treated as a new basic 
model and must be certified in accordance with the provisions of this 
subpart; except that in addition to satisfying all requirements of this 
subpart, the manufacturer shall also maintain records that demonstrate 
that modifications have been

[[Page 983]]

made to all units of the new basic model prior to distribution in 
commerce.
    (b) If a basic model is not properly certified in accordance with 
the requirements of this subpart, the Secretary may seek, among other 
remedies, injunctive action to prohibit distribution in commerce of such 
basic model.



Sec. 431.386  Remedies.

    If the Secretary determines that a basic model of any covered 
equipment does not comply with an applicable energy conservation 
standard:
    (a) The Secretary will notify the manufacturer, private labeler, or 
any other person as required, of this finding and of the Secretary's 
intent to seek a judicial order restraining further distribution in 
commerce of units of such a basic model unless the manufacturer, private 
labeler or other person as required, delivers, within 15 calendar days, 
a satisfactory statement to the Secretary, of the steps the 
manufacturer, private labeler or other person will take to insure that 
the noncompliant basic model will no longer be distributed in commerce. 
The Secretary will monitor the implementation of such statement.
    (b) If the manufacturer, private labeler or any other person as 
required, fails to stop distribution of the noncompliant basic model, 
the Secretary may seek to restrain such violation in accordance with 
sections 334 and 345 of the Act.
    (c) The Secretary will determine whether the facts of the case 
warrant the assessment of civil penalties for knowing violations in 
accordance with sections 333 and 345 of the Act.



Sec. 431.387  Hearings and appeals.

    (a) Under sections 333(d) and 345 of the Act, before issuing an 
order assessing a civil penalty against any person, the Secretary must 
provide to such a person a notice of the proposed penalty. Such notice 
must inform the person that such person can choose (in writing within 30 
days after receipt of the notice) to have the procedures of paragraph 
(c) of this section (in lieu of those in paragraph (b) of this section) 
apply with respect to such assessment.
    (b)(1) Unless a person elects, within 30 calendar days after receipt 
of a notice under paragraph (a) of this section, to have paragraph (c) 
of this section apply with respect to the civil penalty under paragraph 
(a), the Secretary will assess the penalty, by order, after providing an 
opportunity for an agency hearing under 5 U.S.C. 554, before an 
administrative law judge appointed under 5 U.S.C. 3105, and making a 
determination of violation on the record. Such assessment order will 
include the administrative law judge's findings and the basis for such 
assessment.
    (2) Any person against whom the Secretary assesses a penalty under 
this paragraph may, within 60 calendar days after the date of the order 
assessing such penalty, initiate action in the United States Court of 
Appeals for the appropriate judicial circuit for judicial review of such 
order in accordance with 5 U.S.C. chapter 7. The court will have 
jurisdiction to enter a judgment affirming, modifying, or setting aside 
in whole or in part, the order of the Secretary, or the court may remand 
the proceeding to the Secretary for such further action as the court may 
direct.
    (c)(1) In the case of any civil penalty with respect to which the 
procedures of this paragraph have been elected, the Secretary will 
promptly assess such penalty, by order, after the date of the receipt of 
the notice under paragraph (a) of this section of the proposed penalty.
    (2) If the person has not paid the civil penalty within 60 calendar 
days after the assessment has been made under paragraph (c)(1) of this 
section, the Secretary will institute an action in the appropriate 
District Court of the United States for an order affirming the 
assessment of the civil penalty. The court will have authority to review 
de novo the law and the facts involved and jurisdiction to enter a 
judgment enforcing, modifying, and enforcing as so modified, or setting 
aside in whole or in part, such assessment.
    (3) Any election to have this paragraph apply can only be revoked 
with the consent of the Secretary.
    (d) If any person fails to pay an assessment of a civil penalty 
after it has become a final and unappealable order under paragraph (b) 
of this section, or

[[Page 984]]

after the appropriate District Court has entered final judgment in favor 
of the Secretary under paragraph (c) of this section, the Secretary will 
institute an action to recover the amount of such penalty in any 
appropriate District Court of the United States. In such action, the 
validity and appropriateness of such final assessment order or judgment 
will not be subject to review.
    (e)(1) In accordance with the provisions of sections 333(d)(5)(A) 
and 345 of the Act and notwithstanding the provisions of title 28, 
United States Code, or Section 502(c) of the Department of Energy 
Organization Act, the General Counsel of the Department of Energy (or 
any attorney or attorneys within DOE designated by the Secretary) will 
represent the Secretary, and will supervise, conduct, and argue any 
civil litigation to which paragraph (c) of this section applies 
(including any related collection action under paragraph (d) of this 
section) in a court of the United States or in any other court, except 
the Supreme Court of the United States. However, the Secretary or the 
General Counsel will consult with the Attorney General concerning such 
litigation and the Attorney General will provide, on request, such 
assistance in the conduct of such litigation as may be appropriate.

Sec. Appendix A to Subpart U of Part 431--Sampling Plan for Enforcement 
                       Testing of Electric Motors

    Step 1. The first sample size (n1) must be five or more 
units.
    Step 2. Compute the mean (X1 of the measured energy 
performance of the n1 units in the first sample as follows:
[GRAPHIC] [TIFF OMITTED] TR83AD04.005

where Xi is the measured full-load efficiency of unit i.
    Step 3. Compute the sample standard deviation (S1) of the 
measured full-load efficiency of the n1 units in the first 
sample as follows:
[GRAPHIC] [TIFF OMITTED] TR83AD04.006

    Step 4. Compute the standard error (SE(X1)) of the mean 
full-load efficiency of the first sample as follows:
[GRAPHIC] [TIFF OMITTED] TR83AD04.007

    Step 5. Compute the lower control limit (LCL1) for the 
mean of the first sample using RE as the desired mean as follows:
[GRAPHIC] [TIFF OMITTED] TR83AD04.008

where: RE is the applicable EPCA nominal full-load efficiency when the 
test is to determine compliance with the applicable statutory standard, 
or is the labeled nominal full-load efficiency when the test is to 
determine compliance with the labeled efficiency value, and t is the 
2.5th percentile of a t-distribution for a sample size of n1, 
which yields a 97.5 percent confidence level for a one-tailed t-test.
    Step 6. Compare the mean of the first sample (X1) with 
the lower control limit (LCL1) to determine one of the 
following:
    (i) If the mean of the first sample is below the lower control 
limit, then the basic model is in non-compliance and testing is at an 
end.
    (ii) If the mean is equal to or greater than the lower control 
limit, no final determination of compliance or non-compliance can be 
made; proceed to Step 7.
    Step 7. Determine the recommended sample size (n) as follows:
    [GRAPHIC] [TIFF OMITTED] TR83AD04.009
    
where S1, RE and t have the values used in Steps 3 and 5, 
respectively. The factor
[GRAPHIC] [TIFF OMITTED] TR83AD04.010


[[Page 985]]


is based on a 20 percent tolerance in the total power loss at full-load 
and fixed output power.
    Given the value of n, determine one of the following:
    (i) If the value of n is less than or equal to n1 and if 
the mean energy efficiency of the first sample (X1) is equal 
to or greater than the lower control limit (LCL1), the basic 
model is in compliance and testing is at an end.
    (ii) If the value of n is greater than n1, the basic model is in 
non-compliance. The size of a second sample n2 is determined 
to be the smallest integer equal to or greater than the difference n-
n1. If the value of n2 so calculated is greater 
than 20-n1, set n2 equal to 20-n1.
    Step 8. Compute the combined (X2) mean of the measured 
energy performance of the n1 and n2 units of the 
combined first and second samples as follows:
[GRAPHIC] [TIFF OMITTED] TR83AD04.011

    Step 9. Compute the standard error (SE(X2)) of the mean 
full-load efficiency of the n1 and n2 units in the 
combined first and second samples as follows:
[GRAPHIC] [TIFF OMITTED] TR83AD04.012

(Note that S1 is the value obtained above in Step 3.)
    Step 10. Set the lower control limit (LCL2) to,
    [GRAPHIC] [TIFF OMITTED] TR83AD04.013
    
where t has the value obtained in Step 5, and compare the combined 
sample mean (X2) to the lower control limit (LCL2) 
to find one of the following:
    (i) If the mean of the combined sample (X2) is less than 
the lower control limit (LCL2), the basic model is in non-
compliance and testing is at an end.
    (ii) If the mean of the combined sample (X2) is equal to 
or greater than the lower control limit (LCL2), the basic 
model is in compliance and testing is at an end.

                       Manufacturer-Option Testing

    If a determination of non-compliance is made in Steps 6, 7 or 10, of 
this appendix A, the manufacturer may request that additional testing be 
conducted, in accordance with the following procedures.
    Step A. The manufacturer requests that an additional number, 
n3, of units be tested, with n3 chosen such that 
n1 + n2 + n3 does not exceed 20.
    Step B. Compute the mean full-load efficiency, standard error, and 
lower control limit of the new combined sample in accordance with the 
procedures prescribed in Steps 8, 9, and 10, of this appendix A.
    Step C. Compare the mean performance of the new combined sample to 
the lower control limit (LCL2) to determine one of the 
following:
    (a) If the new combined sample mean is equal to or greater than the 
lower control limit, the basic model is in compliance and testing is at 
an end.
    (b) If the new combined sample mean is less than the lower control 
limit and the value of n1 + n2 + n3 is 
less than 20, the manufacturer may request that additional units be 
tested. The total of all units tested may not exceed 20. Steps A, B, and 
C are then repeated.
    (c) Otherwise, the basic model is determined to be in non-
compliance.

Sec. 431.401  Petitions for waiver and interim waiver.

    (a) General information. This section provides a means for seeking 
waivers of the test procedure requirements of this part for basic models 
that meet the requirements of paragraph (a)(1) of this section. In 
granting a waiver or interim waiver, DOE will not change the energy use 
or efficiency metric that the manufacturer must use to certify 
compliance with the applicable energy conservation standard and to make 
representations about the energy use or efficiency of the covered 
equipment. The granting of a waiver or interim waiver by DOE does not 
exempt such basic models from any other regulatory requirement contained 
in this part or the certification and compliance requirements of 10 CFR 
part 429 and specifies an alternative method for testing the basic 
model(s) addressed in the waiver.
    (1) Any interested person may submit a petition to waive for a 
particular basic model the requirements of any uniform test method 
contained in this part, upon the grounds that either the basic model 
contains one or more design characteristics that prevent testing of the 
basic model according to the prescribed test procedures or cause the 
prescribed test procedures to evaluate

[[Page 986]]

the basic model in a manner so unrepresentative of its true energy or 
water consumption characteristics as to provide materially inaccurate 
comparative data.
    (2) Manufacturers of basic model(s) subject to a waiver or interim 
waiver are responsible for complying with the other requirements of this 
part and with the requirements of 10 CFR part 429 regardless of the 
person that originally submitted the petition for waiver and/or interim 
waiver. The filing of a petition for waiver and/or interim waiver shall 
not constitute grounds for noncompliance with any requirements of this 
part.
    (3) All correspondence regarding waivers and interim waivers must be 
submitted to DOE either electronically to [email protected] 
(preferred method of transmittal) or by mail to U.S. Department of 
Energy, Building Technologies Program, Test Procedure Waiver, 1000 
Independence Avenue SW., Mailstop EE-5B, Washington, DC 20585-0121.
    (b) Petition content and publication. (1) Each petition for waiver 
must:
    (i) Identify the particular basic model(s) for which a waiver is 
requested, each brand name under which the identified basic model(s) 
will be distributed in commerce, the design characteristic(s) 
constituting the grounds for the petition, and the specific requirements 
sought to be waived, and must discuss in detail the need for the 
requested waiver;
    (ii) Identify manufacturers of all other basic models distributed in 
commerce in the United States and known to the petitioner to incorporate 
design characteristic(s) similar to those found in the basic model that 
is the subject of the petition;
    (iii) Include any alternate test procedures known to the petitioner 
to evaluate the performance of the equipment type in a manner 
representative of the energy and/or water consumption characteristics of 
the basic model; and
    (iv) Be signed by the petitioner or an authorized representative. In 
accordance with the provisions set forth in 10 CFR 1004.11, any request 
for confidential treatment of any information contained in a petition 
for waiver or in supporting documentation must be accompanied by a copy 
of the petition, application or supporting documentation from which the 
information claimed to be confidential has been deleted. DOE will 
publish in the Federal Register the petition and supporting documents 
from which confidential information, as determined by DOE, has been 
deleted in accordance with 10 CFR 1004.11 and will solicit comments, 
data and information with respect to the determination of the petition.
    (2) Each petition for interim waiver must reference the related 
petition for waiver by identifying the particular basic model(s) for 
which a waiver is being sought. Each petition for interim waiver must 
demonstrate likely success of the petition for waiver and address what 
economic hardship and/or competitive disadvantage is likely to result 
absent a favorable determination on the petition for interim waiver. 
Each petition for interim waiver must be signed by the petitioner or an 
authorized representative.
    (c) Notification to other manufacturers. (1) Each petitioner for 
interim waiver must, upon publication of a grant of an interim waiver in 
the Federal Register, notify in writing all known manufacturers of 
domestically marketed basic models of the same equipment class (as 
specified in the relevant subpart of 10 CFR part 431), and of other 
equipment classes known to the petitioner to use the technology or have 
the characteristic at issue in the waiver. The notice must include a 
statement that DOE has published the interim waiver and petition for 
waiver in the Federal Register and the date the petition for waiver was 
published. The notice must also include a statement that DOE will 
receive and consider timely written comments on the petition for waiver. 
Within five working days, each petitioner must file with DOE a statement 
certifying the names and addresses of each person to whom a notice of 
the petition for waiver has been sent.
    (2) If a petitioner does not request an interim waiver and 
notification has not been provided pursuant to paragraph (c)(1) of this 
section, each petitioner, after filing a petition for waiver with DOE, 
and after the petition for waiver has been published in the Federal

[[Page 987]]

Register, must, within five working days of such publication, notify in 
writing all known manufacturers of domestically marketed basic models of 
the same equipment class (as listed in the relevant subpart of 10 CFR 
part 431), and of other equipment classes known to the petitioner to use 
the technology or have the characteristic at issue in the waiver. The 
notice must include a statement that DOE has published the petition in 
the Federal Register and the date the petition for waiver was published. 
Within five working days of the publication of the petition in the 
Federal Register, each petitioner must file with DOE a statement 
certifying the names and addresses of each person to whom a notice of 
the petition for waiver has been sent.
    (d) Public comment and rebuttal. (1) Any person submitting written 
comments to DOE with respect to an interim waiver must also send a copy 
of the comments to the petitioner by the deadline specified in the 
notice.
    (2) Any person submitting written comments to DOE with respect to a 
petition for waiver must also send a copy of such comments to the 
petitioner.
    (3) A petitioner may, within 10 working days of the close of the 
comment period specified in the Federal Register, submit a rebuttal 
statement to DOE. A petitioner may rebut more than one comment in a 
single rebuttal statement.
    (e) Provisions specific to interim waivers--(1) Disposition of 
application. If administratively feasible, DOE will notify the applicant 
in writing of the disposition of the petition for interim waiver within 
30 business days of receipt of the application. Notice of DOE's 
determination on the petition for interim waiver will be published in 
the Federal Register.
    (2) Criteria for granting. DOE will grant an interim waiver from the 
test procedure requirements if it appears likely that the petition for 
waiver will be granted and/or if DOE determines that it would be 
desirable for public policy reasons to grant immediate relief pending a 
determination on the petition for waiver.
    (f) Provisions specific to waivers--(1) Disposition of application. 
The petitioner shall be notified in writing as soon as practicable of 
the disposition of each petition for waiver. DOE shall issue a decision 
on the petition as soon as is practicable following receipt and review 
of the Petition for Waiver and other applicable documents, including, 
but not limited to, comments and rebuttal statements.
    (2) Criteria for granting. DOE will grant a waiver from the test 
procedure requirements if DOE determines either that the basic model(s) 
for which the waiver was requested contains a design characteristic that 
prevents testing of the basic model according to the prescribed test 
procedures, or that the prescribed test procedures evaluate the basic 
model in a manner so unrepresentative of its true energy or water 
consumption characteristics as to provide materially inaccurate 
comparative data. DOE may grant a waiver subject to conditions, which 
may include adherence to alternate test procedures specified by DOE. DOE 
will promptly publish in the Federal Register notice of each waiver 
granted or denied, and any limiting conditions of each waiver granted.
    (g) Extension to additional basic models. A petitioner may request 
that DOE extend the scope of a waiver or an interim waiver to include 
additional basic models employing the same technology as the basic 
model(s) set forth in the original petition. DOE will publish any such 
extension in the Federal Register.
    (h) Duration. (1) Within one year of issuance of an interim waiver, 
DOE will either:
    (i) Publish in the Federal Register a determination on the petition 
for waiver; or
    (ii) Publish in the Federal Register a new or amended test procedure 
that addresses the issues presented in the waiver.
    (2) When DOE amends the test procedure to address the issues 
presented in a waiver, the waiver will automatically terminate on the 
date on which use of that test procedure is required to demonstrate 
compliance.
    (i) Compliance Certification. (1) If the alternate test procedure 
specified in the interim waiver differs from the alternate test 
procedure specified by

[[Page 988]]

DOE in a subsequent decision and order granting the petition for waiver, 
a manufacturer who has already certified basic models using the 
procedure permitted in DOE's grant of an interim test procedure waiver 
is not required to re-test and re-rate those basic models so long as: 
The manufacturer used that alternative procedure to certify the 
compliance of the basic model after DOE granted the company's interim 
waiver request; changes have not been made to those basic models that 
would cause them to use more energy or otherwise be less energy 
efficient; and the manufacturer does not modify the certified rating. 
However, if the alternate test procedure specified in the interim waiver 
differs from the alternate test procedure specified by DOE in a 
subsequent decision and order granting the petition for waiver and if 
specified by DOE in the decision and order, the manufacturer must re-
test and re-certify compliance using the procedure specified by DOE in 
the decision and order by the time of the next annual certification.
    (2) After DOE publishes a decision and order in the Federal 
Register, a manufacturer must use the test procedure contained in that 
notice to rate any basic models covered by the waiver that have not yet 
been certified to DOE and for any future testing of any basic model(s) 
covered by the decision and order.
    (j) Petition for waiver required of other manufactures. Within 60 
days after DOE issues a waiver to a manufacturer for equipment employing 
a particular technology or having a particular characteristic, any 
manufacturer currently distributing in commerce in the United States 
equipment employing a technology or characteristic that results in the 
same need for a waiver (as specified by DOE in the published decision 
and order on the petition in the Federal Register) must submit a 
petition for waiver pursuant to the requirements of this section. 
Manufacturers not currently distributing such equipment in commerce in 
the United States must petition for and be granted a waiver prior to 
distribution in commerce in the United States. Manufacturers may also 
submit a request for interim waiver pursuant to the requirements of this 
section.
    (k) Rescission or modification. (1) DOE may rescind or modify a 
waiver or interim waiver at any time upon DOE's determination that the 
factual basis underlying the petition for waiver or interim waiver is 
incorrect, or upon a determination that the results from the alternate 
test procedure are unrepresentative of the basic model(s)' true energy 
consumption characteristics. Waivers and interim waivers are conditioned 
upon the validity of statements, representations, and documents provided 
by the requestor; any evidence that the original grant of a waiver or 
interim waiver was based upon inaccurate information will weigh against 
continuation of the waiver. DOE's decision will specify the basis for 
its determination and, in the case of a modification, will also specify 
the change to the authorized test procedure.
    (2) A person may request that DOE rescind or modify a waiver or 
interim waiver issued to that person if the person discovers an error in 
the information provided to DOE as part of its petition, determines that 
the waiver is no longer needed, or for other appropriate reasons. In a 
request for rescission, the requestor must provide a statement 
explaining why it is requesting rescission. In a request for 
modification, the requestor must explain the need for modification to 
the authorized test procedure and detail the modifications needed and 
the corresponding impact on measured energy consumption.
    (3) DOE will publish a proposed rescission or modification (DOE-
initiated or at the request of the original requestor) in the Federal 
Register for public comment. A requestor may, within 10 working days of 
the close of the comment period specified in the proposed rescission or 
modification published in the Federal Register, submit a rebuttal 
statement to DOE. A requestor may rebut more than one comment in a 
single rebuttal statement.
    (4) DOE will publish its decision in the Federal Register. DOE's 
determination will be based on relevant information contained in the 
record and any comments received.

[[Page 989]]

    (5) After the effective date of a rescission, any basic model(s) 
previously subject to a waiver must be tested and certified using the 
applicable DOE test procedure in 10 CFR part 431.
    (l) Revision of regulation. As soon as practicable after the 
granting of any waiver, DOE will publish in the Federal Register a 
notice of proposed rulemaking to amend its regulations so as to 
eliminate any need for the continuation of such waiver. As soon 
thereafter as practicable, DOE will publish in the Federal Register a 
final rule.
    (m) To exhaust administrative remedies, any person aggrieved by an 
action under this section must file an appeal with the DOE's Office of 
Hearings and Appeals as provided in 10 CFR part 1003, subpart C.

[79 FR 26601, May 9, 2014]



Sec. 431.402  Preemption of State regulations for commercial
HVAC & WH products.

    Beginning on the effective date of such standard, an energy 
conservation standard set forth in this part for a commercial HVAC & WH 
product supersedes any State or local regulation concerning the energy 
efficiency or energy use of that product, except as provided for in 
Section 345(b)(2)(B)-(D) of the Act.



Sec. 431.403  Maintenance of records for electric motors.

    (a) Manufacturers of electric motors must establish, maintain and

verification of any AEDM used under this part;
    (3) Any written certification received from a certification program, 
including a certificate or conformity, relied on under the provisions of 
this part;
    (b) You must organize such records and index them so that they are 
readily accessible for review. The records must include the supporting 
test data associated with tests performed on any test units to satisfy 
the requirements of this part (except tests performed by DOE).
    (c) For each basic model, you must retain all such records for a 
period of two years from the date that production of all units of that 
basic model has ceased. You must retain records in a form allowing ready 
access to DOE, upon request.

[76 FR 12505, Mar. 7, 2011]



Sec. 431.404  Imported electric motors.

    (a) Under sections 331 and 345 of the Act, any person importing an 
electric motor into the United States must comply with the provisions of 
the Act and of this part, and is subject to the remedies of this part.
    (b) Any electric motor offered for importation in violation of the 
Act and of this part will be refused admission into the customs 
territory of the United States under rules issued by the Secretary of 
the Treasury, except that the Secretary of the Treasury may, by such 
rules, authorize the importation of such electric motor upon such terms 
and conditions (including the furnishing of a bond) as may appear to the 
Secretary of the Treasury appropriate to ensure that such electric motor 
will not violate the Act and this part, or will be exported or abandoned 
to the United States.

[76 FR 12505, Mar. 7, 2011]



Sec. 431.405  Exported electric motors.

    Under Sections 330 and 345 of the Act, this part does not apply to 
any electric motor if:
    (a) Such electric motor is manufactured, sold, or held for sale for 
export from the United States (or such electric motor was imported for 
export), unless such electric motor is, in fact, distributed in commerce 
for use in the United States; and,
    (b) Such electric motor, when distributed in commerce, or any 
container in which it is enclosed when so distributed, bears a stamp or 
label stating that such electric motor is intended for export.

    Subpart W_Petitions To Exempt State Regulation From Preemption; 
           Petitions To Withdraw Exemption of State Regulation

    Source: 69 FR 61941, Oct. 21, 2004, unless otherwise noted. 
Redesignated at 70 FR 60417, Oct. 18, 2005.



Sec. 431.421  Purpose and scope.

    (a) The regulations in this subpart prescribe the procedures to be 
followed in connection with petitions requesting a rule that a State 
regulation prescribing an energy conservation standard or other 
requirement respecting energy use or energy efficiency of a type (or 
class) of covered equipment not be preempted.
    (b) The regulations in this subpart also prescribe the procedures to 
be followed in connection with petitions to withdraw a rule exempting a 
State regulation prescribing an energy conservation standard or other 
requirement respecting energy use or energy efficiency of a type (or 
class) of covered equipment.



Sec. 431.422  Prescriptions of a rule.

    (a) Criteria for exemption from preemption. Upon petition by a State 
which has prescribed an energy conservation standard or other 
requirement for a type or class of covered equipment for which a Federal 
energy conservation standard is applicable, the Secretary shall 
prescribe a rule that such standard not be preempted if he/she 
determines that the State has established by a preponderance of evidence 
that such requirement is needed to meet unusual and compelling State or 
local energy interests. For the purposes of this regulation, the term 
``unusual and

[[Page 991]]

compelling State or local energy interests'' means interests which are 
substantially different in nature or magnitude from those prevailing in 
the U.S. generally, and are such that when evaluated within the context 
of the State's energy plan and forecast, the costs, benefits, burdens, 
and reliability of energy savings resulting from the State regulation 
make such regulation preferable or necessary when measured against the 
costs, benefits, burdens, and reliability of alternative approaches to 
energy savings or production, including reliance on reasonably 
predictable market-induced improvements in efficiency of all equipment 
subject to the State regulation. The Secretary may not prescribe such a 
rule if he finds that interested persons have established, by a 
preponderance of the evidence, that the State's regulation will 
significantly burden manufacturing, marketing, distribution, sale or 
servicing of the covered equipment on a national basis. In determining 
whether to make such a finding, the Secretary shall evaluate all 
relevant factors including: The extent to which the State regulation 
will increase manufacturing or distribution costs of manufacturers, 
distributors, and others; the extent to which the State regulation will 
disadvantage smaller manufacturers, distributors, or dealers or lessen 
competition in the sale of the covered equipment in the State; the 
extent to which the State regulation would cause a burden to 
manufacturers to redesign and produce the covered equipment type (or 
class), taking into consideration the extent to which the regulation 
would result in a reduction in the current models, or in the projected 
availability of models, that could be shipped on the effective date of 
the regulation to the State and within the U.S., or in the current or 
projected sales volume of the covered equipment type (or class) in the 
State and the U.S.; and the extent to which the State regulation is 
likely to contribute significantly to a proliferation of State 
commercial and industrial equipment efficiency requirements and the 
cumulative impact such requirements would have. The Secretary may not 
prescribe such a rule if he/she finds that such a rule will result in 
the unavailability in the State of any covered equipment (or class) of 
performance characteristics (including reliability), features, sizes, 
capacities, and volumes that are substantially the same as those 
generally available in the State at the time of the Secretary's finding. 
The failure of some classes (or types) to meet this criterion shall not 
affect the Secretary's determination of whether to prescribe a rule for 
other classes (or types).
    (1) Requirements of petition for exemption from preemption. A 
petition from a State for a rule for exemption from preemption shall 
include the information listed in paragraphs (a)(1)(i) through 
(a)(1)(vi) of this section. A petition for a rule and correspondence 
relating to such petition shall be available for public review except 
for confidential or proprietary information submitted in accordance with 
the Department of Energy's Freedom of Information Regulations set forth 
in 10 CFR part 1004.
    (i) The name, address, and telephone number of the petitioner;
    (ii) A copy of the State standard for which a rule exempting such 
standard is sought;
    (iii) A copy of the State's energy plan and forecast;
    (iv) Specification of each type or class of covered equipment for 
which a rule exempting a standard is sought;
    (v) Other information, if any, believed to be pertinent by the 
petitioner; and
    (vi) Such other information as the Secretary may require.
    (b) Criteria for exemption from preemption when energy emergency 
conditions exist within State. Upon petition by a State which has 
prescribed an energy conservation standard or other requirement for a 
type or class of covered equipment for which a Federal energy 
conservation standard is applicable, the Secretary may prescribe a rule, 
effective upon publication in the Federal Register, that such regulation 
not be preempted if he determines that in addition to meeting the 
requirements of paragraph (a) of this Section the State has established 
that: an energy emergency condition exists within the State that 
imperils the health,

[[Page 992]]

safety, and welfare of its residents because of the inability of the 
State or utilities within the State to provide adequate quantities of 
gas or electric energy to its residents at less than prohibitive costs; 
and cannot be substantially alleviated by the importation of energy or 
the use of interconnection agreements; and the State regulation is 
necessary to alleviate substantially such condition.
    (1) Requirements of petition for exemption from preemption when 
energy emergency conditions exist within a State. A petition from a 
State for a rule for exemption from preemption when energy emergency 
conditions exist within a State shall include the information listed in 
paragraphs (a)(1)(i) through (a)(1)(vi) of this section. A petition 
shall also include the information prescribed in paragraphs (b)(1)(i) 
through (b)(1)(iv) of this section, and shall be available for public 
review except for confidential or proprietary information submitted in 
accordance with the Department of Energy's Freedom of Information 
Regulations set forth in 10 CFR part 1004:
    (i) A description of the energy emergency condition which exists 
within the State, including causes and impacts.
    (ii) A description of emergency response actions taken by the State 
and utilities within the State to alleviate the emergency condition;
    (iii) An analysis of why the emergency condition cannot be 
alleviated substantially by importation of energy or the use of 
interconnection agreements;
    (iv) An analysis of how the State standard can alleviate 
substantially such emergency condition.
    (c) Criteria for withdrawal of a rule exempting a State standard. 
Any person subject to a State standard which, by rule, has been exempted 
from Federal preemption and which prescribes an energy conservation 
standard or other requirement for a type or class of covered equipment, 
when the Federal energy conservation standard for such equipment 
subsequently is amended, may petition the Secretary requesting that the 
exemption rule be withdrawn. The Secretary shall consider such petition 
in accordance with the requirements of paragraph (a) of this section, 
except that the burden shall be on the petitioner to demonstrate that 
the exemption rule received by the State should be withdrawn as a result 
of the amendment to the Federal standard. The Secretary shall withdraw 
such rule if he determines that the petitioner has shown the rule should 
be withdrawn.
    (1) Requirements of petition to withdraw a rule exempting a State 
standard. A petition for a rule to withdraw a rule exempting a State 
standard shall include the information prescribed in paragraphs 
(c)(1)(i) through (c)(1)(vii) of this section, and shall be available 
for public review, except for confidential or proprietary information 
submitted in accordance with the Department of Energy's Freedom of 
Information Regulations set forth in 10 CFR part 1004:
    (i) The name, address and telephone number of the petitioner;
    (ii) A statement of the interest of the petitioner for which a rule 
withdrawing an exemption is sought;
    (iii) A copy of the State standard for which a rule withdrawing an 
exemption is sought;
    (iv) Specification of each type or class of covered equipment for 
which a rule withdrawing an exemption is sought;
    (v) A discussion of the factors contained in paragraph (a) of this 
section;
    (vi) Such other information, if any, believed to be pertinent by the 
petitioner; and
    (vii) Such other information as the Secretary may require.
    (2) [Reserved]



Sec. 431.423  Filing requirements.

    (a) Service. All documents required to be served under this subpart 
shall, if mailed, be served by first class mail. Service upon a person's 
duly authorized representative shall constitute service upon that 
person.
    (b) Obligation to supply information. A person or State submitting a 
petition is under a continuing obligation to provide any new or newly 
discovered information relevant to that petition. Such information 
includes, but is not limited to, information regarding any other 
petition or request for action

[[Page 993]]

subsequently submitted by that person or State.
    (c) The same or related matters. A person or State submitting a 
petition or other request for action shall state whether to the best 
knowledge of that petitioner the same or related issue, act, or 
transaction has been or presently is being considered or investigated by 
any State agency, department, or instrumentality.
    (d) Computation of time. (1) Computing any period of time prescribed 
by or allowed under this subpart, the day of the action from which the 
designated period of time begins to run is not to be included. If the 
last day of the period is Saturday, or Sunday, or Federal legal holiday, 
the period runs until the end of the next day that is neither a 
Saturday, or Sunday or Federal legal holiday.
    (2) Saturdays, Sundays, and intervening Federal legal holidays shall

Sec. 431.442  Definitions.

    The following definitions are applicable to this subpart:
    Alternative efficiency determination method, or AEDM, means, with 
respect to a small electric motor, a method of calculating the total 
power loss and average full-load efficiency.
    Average full-load efficiency means the arithmetic mean of the full-
load efficiencies of a population of small electric motors of duplicate 
design, where the full-load efficiency of each motor in the population 
is the ratio (expressed as a percentage) of the motor's useful power 
output to its total power input when the motor is operated at its full 
rated load, rated voltage, and rated frequency.
    Basic model means, with respect to a small electric motor, all units 
of a given type of small electric motor (or class thereof) manufactured 
by a single manufacturer, and which have the same rating, have 
electrical characteristics that are essentially identical, and do not 
have any differing physical or functional characteristics that affect 
energy consumption or efficiency. For the purpose of this definition, 
``rating'' means a combination of the small electric motor's group 
(i.e., capacitor-start, capacitor-run; capacitor-start, induction-run; 
or polyphase), horsepower rating (or standard kilowatt equivalent), and 
number of poles with respect to which Sec. 431.446 prescribes nominal 
full load efficiency standards.
    CSA means Canadian Standards Association.
    DOE or the Department means the U.S. Department of Energy.
    EPCA means the Energy Policy and Conservation Act, as amended, 42 
U.S.C. 6291-6317.
    IEC means International Electrotechnical Commission.
    IEEE means Institute of Electrical and Electronics Engineers, Inc.

[74 FR 32072, July 7, 2009, as amended at 77 FR 26638, May 4, 2012]



Sec. 431.445  Determination of small electric motor efficiency.

    (a) Scope. When a party determines the energy efficiency of a small 
electric motor to comply with an obligation imposed on it by or pursuant 
to Part A-1 of Title III of EPCA, 42 U.S.C. 6311-6317, this section 
applies.
    (b) Provisions applicable to all small electric motors--(1) General 
requirements. The average full-load efficiency of each basic model of 
small electric motor must be determined either by testing in accordance 
with Sec. 431.444 of this subpart, or by application of an alternative 
efficiency determination method (AEDM) that meets the requirements of 
paragraphs (a)(2) and (3) of this section, provided, however, that an 
AEDM may be used to determine the average full-load efficiency of one or 
more of a manufacturer's basic models only if the average full-load 
efficiency of at least five of its other basic models is determined 
through testing.
    (2) Alternative efficiency determination method. An AEDM applied to 
a basic model must be:
    (i) Derived from a mathematical model that represents the mechanical 
and electrical characteristics of that basic model, and
    (ii) Based on engineering or statistical analysis, computer 
simulation or modeling, or other analytic evaluation of performance 
data.
    (3) Substantiation of an alternative efficiency determination 
method. Before an AEDM is used, its accuracy and reliability must be 
substantiated as follows:

[[Page 997]]

    (i) The AEDM must be applied to at least five basic models that have 
been tested in accordance with Sec. 431.444; and
    (ii) The predicted total power loss for each such basic model, 
calculated by applying the AEDM, must be within plus or minus 10 percent 
of the mean total power loss determined from the testing of that basic 
model.
    (4) Subsequent verification of an AEDM. (i) Each manufacturer that 
has used an AEDM under this section shall have available for inspection 
by the Department of Energy records showing the method or methods used; 
the mathematical model, the engineering or statistical analysis, 
computer simulation or modeling, and other analytic evaluation of 
performance data on which the AEDM is based; complete test data, product 
information, and related information that the manufacturer has generated 
or acquired pursuant to paragraph (a)(3) of this section; and the 
calculations used to determine the efficiency and total power losses of 
each basic model to which the AEDM was applied.
    (ii) If requested by the Department, the manufacturer shall conduct 
simulations to predict the performance of particular basic models of 
small electric motors specified by the Department, analyses of previous 
simulations conducted by the manufacturer, sample testing of basic 
models selected by the Department, or a combination of the foregoing.
    (5) Use of a certification program. (i) A manufacturer may use a 
certification program, that DOE has classified as nationally recognized 
under Sec. 431.447, to certify the average full-load efficiency of a 
basic model of small electric motor, and issue a certificate of 
conformity for the small electric motor.
    (ii) For each basic model for which a certification program is not 
used as described in paragraph (b)(5)(i) of this section, any testing of 
a motor to determine its energy efficiency must be carried out in 
accordance with paragraph (c) of this section.
    (c) Additional testing requirements applicable when a certification 
program is not used--(1) Selection of basic models for testing. (i) 
Basic models must be selected for testing in accordance with the 
following criteria:
    (A) Two of the basic models must be among the five basic models that 
have the highest unit volumes of production by the manufacturer in the 
prior year, or during the prior 12 calendar month period beginning in 
2015, whichever is later, and comply with the standards set forth in 
Sec. 431.446;
    (B) The basic models should be of different horsepowers without 
duplication;
    (C) At least one basic model should be selected from each of the 
frame number series for which the manufacturer is seeking compliance; 
and
    (D) Each basic model should have the lowest average full-load 
efficiency among the basic models with the same rating (``rating'' as 
used here has the same meaning as it has in the definition of ``basic 
model'').
    (ii) In any instance where it is impossible for a manufacturer to 
select basic models for testing in accordance with all of these 
criteria, the criteria shall be given priority in the order in which 
they are listed. Within the limits imposed by the criteria, basic models 
shall be selected randomly.
    (2) Selection of units for testing within a basic model. For each 
basic model selected for testing,\1\ a sample of units shall be selected 
at random and tested. The sample shall be comprised of production units 
of the basic model, or units that are representative of such production 
units. The sample size shall be no fewer than five units, except when 
fewer than five units of a basic model would be produced over a 
reasonable period of time (approximately 180 days). In such cases, each 
unit produced shall be tested.
---------------------------------------------------------------------------

    \1\ Components of similar design may be substituted without 
requiring additional testing if the represented measures of energy 
consumption continue to satisfy the applicable sampling provision.
---------------------------------------------------------------------------

    (3) Applying results of testing. When applying the test results to 
determine whether a motor complies with the required average efficiency 
level:
    The average full-load efficiency of the sample, X which is defined 
by
[GRAPHIC] [TIFF OMITTED] TR04MY12.000



[[Page 998]]


where Xi is the measured full-load efficiency of unit i and n 
is the number of units tested, shall satisfy the condition:

 Sec. Appendix A to Subpart Y of Part 431--Uniform Test Method for the 
               Measurement of Energy Consumption of Pumps

    Note: Starting on July 25, 2016, any representations made with 
respect to the energy use or efficiency of pumps subject to testing 
pursuant to 10 CFR 431.464(a) must be made in accordance with the 
results of testing pursuant to this appendix.

                       I. Test Procedure for Pumps

    A. General. To determine the constant load pump energy index 
(PEICL) for bare pumps and pumps sold with electric motors or 
the variable load pump energy index (PEIVL) for pumps sold 
with electric motors and continuous or non-continuous controls, perform 
testing in accordance with HI 40.6-2014, except section 40.6.5.3, ``Test 
report;'' section A.7, ``Testing at temperatures exceeding 30 [deg]C (86 
[deg]F);'' and appendix B, ``Reporting of test results;'' (incorporated 
by reference, see Sec. 431.463) with the modifications and additions as 
noted throughout the provisions below. Where HI 40.6-2014 refers to 
``pump,'' the term refers to the ``bare pump,'' as defined in Sec. 
431.462. Also, for the purposes of applying this appendix, the term 
``volume per unit time,'' as defined in section 40.6.2, ``Terms and 
definitions,'' of HI 40.6-2014 shall be deemed to be synonymous with the 
term ``flow rate'' used throughout that standard and this appendix. In 
addition, the specifications of section 40.6.4.1 of HI 40.6-2014 do not 
apply to ST pumps and the performance of ST bare pumps considers the 
bowl performance only.
    A.1 Scope. Section II of this appendix is applicable to all pumps 
and describes how to calculate the pump energy index (section II.A) 
based on the pump energy rating for the minimally compliant reference 
pump (PERSTD; section II.B) and the constant load pump energy 
rating (PERCL) or variable load pump energy rating 
(PERVL) determined in accordance with one of sections III 
through VII of this appendix, based on the configuration in which the 
pump is distributed in commerce and the applicable testing method 
specified in sections III through VII and as described in Table 1 of 
this appendix.

  this chapter.
*** Includes pumps sold with single-phase induction motors.

    A.2 Section III of this appendix addresses the test procedure 
applicable to bare pumps. This test procedure also applies to pumps sold 
with drivers other than motors and pumps sold with single-phase 
induction motors.
    A.3 Section IV of this appendix addresses the testing-based approach 
for pumps sold with motors, which is applicable to all pumps sold with 
electric motors, including single-phase induction motors. This test 
procedure also applies to pumps sold with controls other than continuous 
or non-continuous controls (e.g., on/off switches).
    A.4 Section V of this appendix addresses the calculation-based 
approach for pumps sold with motors, which applies to:
    (1) Pumps sold with polyphase electric motors regulated by DOE's 
energy conservation standards for electric motors at Sec. 431.25(g), 
and
    (2) Pumps sold with submersible motors.
    A.5 Section VI of this appendix addresses the testing-based approach 
for pumps sold with motors and controls, which is applicable to all 
pumps sold with electric motors (including single-phase induction 
motors) and continuous or non-continuous controls.

approach for pumps sold with motors and controls, which applies to:
    (1) Pumps sold with polyphase electric motors regulated by DOE's 
energy conservation standards for electric motors at Sec. 431.25(g) and 
continuous controls and
    (2) Pumps sold with submersible motors and continuous controls.
    B. Measurement Equipment. For the purposes of measuring pump power 
input, driver power input to the motor or controls, and pump power 
output, the equipment specified in HI 40.6-2014 Appendix C (incorporated 
by reference, see Sec. 431.463) necessary to measure head, speed of 
rotation, flow rate, temperature, torque, and electrical power must be 
used and must comply with the stated accuracy requirements in HI 40.6-
2014 Table 40.6.3.2.3 except as noted in sections III.B, IV.B, V.B, 
VI.B, and VII.B of this appendix. When more than one instrument is used 
to measure a given parameter, the combined accuracy, calculated as the 
root sum of squares of individual instrument accuracies, must meet the 
specified accuracy requirements.
    C. Test Conditions. Conduct testing at full impeller diameter in 
accordance with the test conditions, stabilization requirements, and 
specifications of HI 40.6-2014 (incorporated by reference, see Sec. 
431.463) section 40.6.3, ``Pump efficiency testing;'' section 40.6.4, 
``Considerations when determining the efficiency of a pump;'' section 
40.6.5.4 (including appendix A), ``Test arrangements;'' and section 
40.6.5.5, ``Test conditions.''. For ST pumps, head measurements must be 
based on the bowl assembly total head as described in section A.5 of 
40.6-2014 and the pump power input or driver power input, as applicable, 
must be based on the measured input power to the driver or bare pump, 
respectively; section 40.6.4.1, ``vertically suspended pumps,'' does not 
apply to ST pumps.
    C.1 Nominal Speed of Rotation. Determine the nominal speed of 
rotation based on the range of speeds of rotation at which the pump is 
designed to operate, in accordance with sections I.C.1.1, I.C.1.2, 
I.C.1.3, I.C.1.4, or I.C.1.5 of this appendix, as applicable. When 
determining the range of speeds at which the pump is designed to 
operate, DOE will refer to published data, marketing literature, and 
other publically-available information about the pump model and motor, 
as applicable.
    C.1.1 For pumps sold without motors, select the nominal speed of 
rotation based on the speed for which the pump is designed. For bare 
pumps designed for speeds of rotation including 2,880 to 4,320 
revolutions per minute (rpm), the nominal speed of rotation shall be 
3,600 rpm. For bare pumps designed

[[Page 1013]]

for speeds of rotation including 1,440 to 2,160 rpm, the nominal speed 
of rotation shall be 1,800 rpm.
    C.1.2 For pumps sold with 4-pole induction motors, the nominal speed 
of rotation shall be 1,800 rpm.
    C.1.3 For pumps sold with 2-pole induction motors, the nominal speed 
of rotation shall be 3,600 rpm.
    C.1.4 For pumps sold with non-induction motors where the operating 
range of the pump and motor includes speeds of rotation between 2,880 
and 4,320 rpm, the nominal speed of rotation shall be 3,600 rpm.
    C.1.5 For pumps sold with non-induction motors where the operating 
range of the pump and motor includes speeds of rotation between 1,440 
and 2,160 rpm, the nominal speed of rotation shall be 1,800 rpm.
    C.2 Multi-stage Pumps. For RSV and ST pumps, perform testing on the 
pump with three stages for RSV pumps and nine stages for ST pumps. If 
the basic model of pump being tested is only available with fewer than 
the required number of stages, test the pump with the maximum number of 
stages with which the basic model is distributed in commerce in the 
United States. If the basic model of pump being tested is only available 
with greater than the required number of stages, test the pump with the 
lowest number of stages with which the basic model is distributed in 
commerce in the United States. If the basic model of pump being tested 
is available with both fewer and greater than the required number of 
stages, but not the required number of stages, test the pump with the 
number of stages closest to the required number of stages. If both the 
next lower and next higher number of stages are equivalently close to 
the required number of stages, test the pump with the next higher number 
of stages.
    C.3 Twin Head Pumps. For twin head pumps, perform testing on an 
equivalent single impeller IL pump, constructed by incorporating one of 
the driver and impeller assemblies of the twin head pump being rated 
into an adequate, IL style, single impeller volute and casing. An 
adequate, IL style, single impeller volute and casing means a volute and 
casing for which any physical and functional characteristics that affect 
energy consumption and energy efficiency are the same to their 
corresponding characteristics for a single impeller in the twin head 
pump volute and casing.

                     D. Data Collection and Analysis

    D.1 Damping Devices. Use of damping devices, as described in section 
40.6.3.2.2 of HI 40.6-2014 (incorporated by reference, see Sec. 
431.463), are only permitted to integrate up to the data collection 
interval used during testing.
    D.2 Stabilization. Record data at any tested load point only under 
stabilized conditions, as defined in HI 40.6-2014 section 40.6.5.5.1 
(incorporated by reference, see Sec. 431.463), where a minimum of two 
measurements are used to determine stabilization.
    D.3 Calculations and Rounding. Normalize all measured data to the 
nominal speed of rotation of 3,600 or 1,800 rpm based on the nominal 
speed of rotation selected for the pump in section I.C.1 of this 
appendix, in accordance with the procedures specified in section 
40.6.6.1.1 of HI 40.6-2014 (incorporated by reference, see Sec. 
431.463). Except for the ``expected BEP flow rate,'' all terms and 
quantities refer to values determined in accordance with the procedures 
set forth in this appendix for the rated pump. Perform all calculations 
using raw measured values without rounding. Round PERCL and 
PERVL to three significant digits, and round 
PEICL, and PEIVL values, as applicable, to the 
hundredths place (i.e., 0.01).
    D.4 Pumps with BEP at Run Out.
    Test pumps for which the expected BEP corresponds to a volume rate 
of flow that is within 20 percent of the expected maximum flow rate at 
which the pump is designed to operate continuously or safely (i.e., 
pumps with BEP at run-out) in accordance with the test procedure 
specified in this appendix, but with the following exceptions:
    (1) Use the following seven flow points for determination of BEP in 
sections III.D, IV.D, V.D, VI.D, and VII.D of this appendix instead of 
those specified in those sections: 40, 50, 60, 70, 80, 90, and 100 
percent of the expected.
    (2) Use flow points of 60, 70, 80, 90, and 100 percent of the 
expected maximum flow rate of the pump to determine pump power input or 
driver power input at the specified load points in section III.E.1.1, 
IV.E.1, V.E.1.1, VI.E.1, and VII.E.1.1 of this appendix instead of those 
specified in those sections.
    (3) To determine of PERCL and PERSTD, use load 
points of 65, 90, and 100 percent of the BEP flow rate determined with 
the modified flow points specified in this section I.D.4 of this 
appendix instead of 75, 100, and 110 percent of BEP flow.

                II. Calculation of the Pump Energy Index

    A. Determine the PEI of each tested pump based on the configuration 
in which it is sold, as follows:
    A.1. For pumps rated as bare pumps or pumps sold with motors, 
determine the PEICL using the following equation:

          pumps sold with drivers other than electric motors), section 
          IV (for pumps sold with motors and rated using the testing-
          based approach), or section V (for pumps sold with motors and 
          rated using the calculation-based approach) of this appendix,

    E. Calculating the Variable Load Pump Energy Rating. Determine the 
PERVL of each tested pump using the following equation:
[GRAPHIC] [TIFF OMITTED] TR25JA16.050

Where:

PERVL = the pump energy rating for a variable load (hp);
[omega]i = 0.25;
Piin,c = the normalized driver power input to 
          continuous or non-continuous controls at load point i for the 
          tested pump as determined in accordance with section VI.E.1 of 
          this appendix; and
i = load point corresponding 25, 50, 75, or 100 percent of the BEP flow 
          rate.
    E.1. Determine the driver power input at 100 percent of the measured 
BEP flow rate of the tested pump by employing a least squares regression 
to determine a linear relationship between the measured driver power 
input at the nominal speed of rotation of the pump and the measured flow 
rate, using the following load points: 60, 75, 90, 100, 110, and 120 
percent of the expected BEP flow rate. Use the linear relationship to 
determine the driver power input at the nominal speed of rotation for 
the load point of 100 percent of the measured BEP flow rate of the 
tested pump.
    E.2 Determine the driver power input at 25, 50, and 75 percent of 
the BEP flow rate by measuring the driver power input at the load points 
defined by:
    (1) Those flow rates, and
    (2) The associated head points calculated according to the following 
reference system curve equation:
[GRAPHIC] [TIFF OMITTED] TR25JA16.051

Where:

Hi = pump total head at load point i (ft),
H100% = pump total head at 100 percent of the BEP 
          flow rate and nominal speed of rotation (ft),
Qi = flow rate at load point i (gpm),
Q100% = flow rate at 100 percent of the BEP flow 
          rate and nominal speed of rotation (gpm), and
i = load point corresponding to 25, 50, or 75 percent of the measured 
          BEP flow rate of the tested pump.
    E.2.1. For pumps sold with motors and continuous controls, the 
specific head and flow points must be achieved within 10 percent of the 
calculated values and the measured driver power input must be corrected 
to the exact intended head and flow conditions using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR25JA16.052

Where:

Pi\in,c\ = the corrected driver power input to the continuous 
          or non-continuous controls at load point i (hp),
Hsp,i = the specified total system head at load point i based 
          on the reference system curve (ft),
HM,j = the measured total system head at load point j (ft),

[[Page 1024]]

Qsp,i = the specified total system flow rate at load point i 
          based on the reference system curve (gpm),
QM,j = the measured total system flow rate at load point j 
          (gpm),
PM,j\in,c\ = the measured normalized driver power input to 
          the continuous or non-continuous controls at load point j 
          (hp),
i = specified load point at 25, 50, 75, or 100 percent of BEP flow, and
j = measured load point corresponding to specified load point i.

    E.2.2. For pumps sold with motors and non-continuous controls, the 
head associated with each of the specified flow points shall be no lower 
than 10 percent below that defined by the reference system curve 
equation in section VI.E.2 of this appendix. Only the measured flow 
points must be achieved within 10 percent of the calculated values. 
Correct for flow and head as described in section VI.E.2.1, except do 
not correct measured head values that are higher than the reference 
system curve at the same flow rate; only correct flow rate and head 
values lower than the reference system curve at the same flow rate. For 
head values higher than the system curve, use the measured head points 
directly to calculate PEIVL.

    A.3. Pumps sold with motors not listed in VII.A.1 or VII.A.2 of this 
appendix and pumps sold without continuous controls, including pumps 
sold with non-continuous controls, cannot use this section and must 
apply the test method in section VI of this appendix.

motor electrical measurement equipment must:
    (1) Be capable of measuring true RMS current, true RMS voltage, and 
real power up to the 40th harmonic of fundamental supply source 
frequency, and
    (2) For all instruments used to measure a given parameter, have a 
combined accuracy of 2.0 percent of the measured 
value at the fundamental supply source frequency, where combined 
accuracy is the root sum of squares of individual instrument accuracies.
    C. Test Conditions. The requirements regarding test conditions 
presented in section I.C of this appendix apply to this section VII. 
When testing pumps using a calibrated motor the following conditions 
also apply to the mains power supplied to the motor:

the rated value of the motor,
    (2) Maintain the frequency within 1 percent of 
the rated value of the motor,
    (3) Maintain the voltage unbalance of the power supply within 3 percent of the rated values of the motor, and

point of maximum pump efficiency on the pump efficiency curve, as 
determined in accordance with section 40.6.6.3 of HI 40.6-2014

the ratio of the pump power output divided by the pump power input, as 
specified in Table 40.6.2.1 of HI 40.6-2014 and the calculations

 Sec. Appendix B to Subpart Y of Part 431--Uniform Test Method for the 
    Measurement of Energy Efficiency of Dedicated-Purpose Pool Pumps

    Note: On February 5, 2018 but before July 19, 2021, any 
representations made with respect to the energy use or efficiency of 
dedicated-purpose pool pumps subject to testing pursuant to 10 CFR 
431.464(b) must be made in accordance with the results of testing 
pursuant to this appendix. Any optional representations of energy factor 
(EF) must be accompanied by a representation of weighted energy factor 
(WEF).

           I. Test Procedure for Dedicated-Purpose Pool Pumps

                               A. General

    A.1 Test Method. To determine the weighted energy factor (WEF) for 
dedicated-purpose pool pumps, perform ``wire-to-water'' testing in 
accordance with HI 40.6-2014-B, except section 40.6.4.1, ``Vertically 
suspended pumps''; section 40.6.4.2, ``Submersible pumps''; section 
40.6.5.3, ``Test report''; section 40.6.5.5, ``Test conditions''; 
section 40.6.5.5.2, ``Speed of rotation during testing''; section 
40.6.6.1, ``Translation of test results to rated speed of rotation''; 
section 40.6.6.2, ``Pump efficiency''; section 40.6.6.3, ``Performance 
curve''; section A.7, ``Testing at temperatures exceeding 30 [deg]C 
(86[emsp14] [deg]F)''; and appendix B, ``Reporting of test results''; 
(incorporated by reference, see Sec. 431.463) with the modifications 
and additions as noted throughout the provisions below. Do not use

[[Page 1028]]

the test points specified in section 40.6.5.5.1, ``Test procedure'' of 
HI 40.6-2014-B and instead use those test points specified in section 
D.3 of this appendix for the applicable dedicated-purpose pool pump 
variety and speed configuration. When determining overall efficiency, 
best efficiency point, or other applicable pump energy performance 
information, section 40.6.5.5.1, ``Test procedure''; section 40.6.6.2, 
``Pump efficiency''; and section 40.6.6.3, ``Performance curve'' must be 
used, as applicable. For the purposes of applying this appendix, the 
term ``volume per unit time,'' as defined in section 40.6.2, ``Terms and 
definitions,'' of HI 40.6-2014-B shall be deemed to be synonymous with 
the term ``flow rate'' used throughout that standard and this appendix.
    A.2. Calculations and Rounding. All terms and quantities refer to 
values determined in accordance with the procedures set forth in this 
appendix for the rated pump. Perform all calculations using raw measured 
values without rounding. Round WEF, EF, maximum head, vertical lift, and 
true priming time values to the tenths place (i.e., 0.1) and rated 
hydraulic horsepower to the thousandths place (i.e., 0.001). Round all 
other reported values to the hundredths place unless otherwise 
specified.

                        B. Measurement Equipment

    B.1 For the purposes of measuring flow rate, speed of rotation, 
temperature, and pump power output, the equipment specified in HI 40.6-
2014-B Appendix C (incorporated by reference, see Sec. 431.463) 
necessary to measure head, speed of rotation, flow rate, and temperature 
must be used and must comply with the stated accuracy requirements in HI 
40.6-2014-B Table 40.6.3.2.3, except as specified in section B.1.1 and 
B.1.2 of this appendix. When more than one instrument is used to measure 
a given parameter, the combined accuracy, calculated as the root sum of 
squares of individual instrument accuracies, must meet the specified 
accuracy requirements.
    B.1.1 Electrical measurement equipment for determining the driver 
power input to the motor or controls must be capable of measuring true 
root mean squared (RMS) current, true RMS voltage, and real power up to 
the 40th harmonic of fundamental supply source frequency, and have a 
combined accuracy of 2.0 percent of the measured 
value at the fundamental supply source frequency.
    B.1.2 Instruments for measuring distance (e.g., height above the 
reference plane or water level) must be accurate to and have a 
resolution of at least 0.1 inch.
    B.2 Calibration. Calibration requirements for instrumentation are 
specified in appendix D of HI 40.6-2014-B (incorporated by reference, 
see Sec. 431.463). Historical calibration data may be used to justify 
time periods up to three times longer than those specified in table D.1 
of HI 40.6-2014-B provided the supporting historical data shows 
maintenance of calibration of the given instrument up to the selected 
extended calibration interval on at least two unique occasions, based on 
the interval specified in HI 40.6-2014-B.

                    C. Test Conditions and Tolerances

    C.1 Pump Specifications. Conduct testing at full impeller diameter 
in accordance with the test conditions, stabilization requirements, and 
specifications of HI 40.6-2014-B section 40.6.3, ``Pump efficiency 
testing''; section 40.6.4, ``Considerations when determining the 
efficiency of a pump''; section 40.6.5.4 (including appendix A), ``Test 
arrangements''; and section 40.6.5.5, ``Test conditions'' (incorporated 
by reference, see Sec. 431.463).
    C.2 Power Supply Requirements. The following conditions also apply 
to the mains power supplied to the DPPP motor or controls, if any:
    (1) Maintain the voltage within 5 percent of 
the rated value of the motor,
    (2) Maintain the frequency within 1 percent of 
the rated value of the motor,
    (3) Maintain the voltage unbalance of the power supply within 3 percent of the value with which the motor was rated, 
and
    (4) Maintain total harmonic distortion below 12 percent throughout 
the test.
    C.3 Test Conditions. Testing must be carried out with water that is 
between 50 and 107 [deg]F with less than or equal to 15 nephelometric 
turbidity units (NTU).
    C.4 Tolerances. For waterfall pumps, multi-speed self-priming and 
non-self-priming pool filter pumps, and variable-speed self-priming and 
non-self-priming pool filter pumps all measured load points must be 
within 2.5 percent of the specified head value and 
comply with any specified flow values or thresholds. For all other 
dedicated-purpose pool pumps, all measured load points must be within 
the greater of 2.5 percent of the specified flow 
rate values or 0.5 gpm and comply with any 
specified head values or thresholds.

                  D. Data Collection and Stabilization

    D.1 Damping Devices. Use of damping devices, as described in section 
40.6.3.2.2 of HI 40.6-2014-B (incorporated by reference, see Sec. 
431.463), are only permitted to integrate up to the data collection 
interval used during testing.
    D.2 Stabilization. Record data at any tested load point only under 
stabilized conditions, as defined in HI 40.6-2014-B section 40.6.5.5.1 
(incorporated by reference, see Sec. 431.463), where a minimum of two 
measurements are used to determine stabilization.
    D.3 Test Points. Measure the flow rate in gpm, pump total head in 
ft, the driver power

* In order to apply the test points for two-speed self-priming and non-self-priming pool filter pumps, self-priming pool filter pumps that are greater
  than or equal to 0.711 rated hydraulic horsepower that are two-speed dedicated-purpose pool pumps must also be distributed in commerce either: (1)
  With a pool pump control (variable speed drive and user interface or switch) that changes the speed in response to pre-programmed user preferences and
  allows the user to select the duration of each speed and/or the on/off times or (2) without a pool pump control that has such capability, but without
  which the pump is unable to operate. Two-speed self-priming pool filter pumps greater than or equal to 0.711 rated hydraulic horsepower that do not
  meet these requirements must be tested using the load point for single-speed self-priming or non-self-priming pool filter pumps, as appropriate.
** Qmax_speed@C = Flow at max speed on curve C (gpm)
*** If a two-speed pump has a low speed that results in a flow rate below the specified values, the low speed of that pump shall not be tested.

    E.1 Determination of Weighted Energy Factor. Determine the WEF as a 
ratio of the measured flow and driver power input to the dedicated-
purpose pool pump in accordance with the following equation:
[GRAPHIC] [TIFF OMITTED] TR07AU17.010

Where:

WEF = Weighted Energy Factor in kgal/kWh;
wi = weighting factor at each load point i, as specified in section E.2 
          of this appendix;
Qi = flow at each load point i, in gpm;
Pi = driver power input to the motor (or controls, if present) at each 
          load point i, in watts;
i = load point(s), defined uniquely for each DPPP variety and speed 
          configuration as specified in section D.3 of this appendix; 
          and
n = number of load point(s), defined uniquely for each DPPP variety and 
          speed configuration as specified in section D.3 of this 
          appendix.

    E.2 Weights. When determining WEF, apply the weights specified in 
Table 2 of this appendix for the applicable load points, DPPP varieties, 
and speed configurations:

* In order to apply the test points for two-speed self-priming and non-self-priming pool filter pumps, self-
  priming pool filter pumps that are greater than or equal to 0.711 rated hydraulic horsepower that are two-
  speed dedicated-purpose pool pumps must also be distributed in commerce either: (1) With a pool pump control
  (variable speed drive and user interface or switch) that changes the speed in response to pre-programmed user
  preferences and allows the user to select the duration of each speed and/or the on/off times or (2) without a
  pool pump control that has such capability, but without which the pump is unable to operate. Two-speed self-
  priming pool filter pumps greater than or equal to 0.711 rated hydraulic horsepower that do not meet these
  requirements must be tested using the load point for single-speed self-priming or non-self-priming pool filter
  pumps, as appropriate.

self-priming pool filter pumps, non-self-priming pool filter pumps, and 
waterfall pumps by measuring the head at maximum speed and the minimum 
flow rate at which the pump is designed to operate continuously or 
safely, where the minimum flow rate is assumed to be zero unless stated 
otherwise in the manufacturer literature.

               F. Determination of Self-Priming Capability

    F.1 Test Method. Determine the vertical lift and true priming time 
of non-self-priming pool filter pumps and self-priming pool filter pumps 
that are not already certified as self-priming under NSF/ANSI 50-2015 
(incorporated by reference, see Sec. 431.463) by testing such pumps 
pursuant to section C.3 of appendix C of NSF/ANSI 50-2015, except for 
the modifications and exceptions listed in the following sections F.1.1 
through F.1.5 of this appendix:
    F.1.1 Where section C.3.2, ``Apparatus,'' and section C.3.4, ``Self-
priming capability test method,'' of NSF/ANSI 50-2015 (incorporated by 
reference, see Sec. 431.463) state that the ``suction line must be 
essentially as shown in annex C, figure C.1;'' the phrase ``essentially 
as shown in Annex C, figure C.1'' means:
     The centerline of the pump impeller shaft is 
situated a vertical distance equivalent to the specified vertical lift 
(VL), calculated in accordance with section F.1.1.1. of this appendix, 
above the water level of a water tank of sufficient volume as to 
maintain a constant water surface level for the duration of the test;
     The pump draws water from the water tank with a 
riser pipe that extends below the water level a distance of at least 3 
times the riser pipe diameter (i.e., 3 pipe diameters);
     The suction inlet of the pump is at least 5 pipe 
diameters from any obstructions, 90[deg] bends, valves, or fittings; and
     The riser pipe is of the same pipe diameter as 
the pump suction inlet.
    F.1.1.1 The vertical lift (VL) must be normalized to 5.0 feet at an 
atmospheric pressure of 14.7 psia and a water density of 62.4 lb/ft\3\ 
in accordance with the following equation:

[[Page 1033]]

[GRAPHIC] [TIFF OMITTED] TR07AU17.014

Where:

VL = vertical lift of the test apparatus from the waterline to the 
          centerline of the pump impeller shaft, in ft;
[rho]test = density of test fluid, in lb/ft\3\; and
Pabs,test = absolute barometric pressure of test apparatus location at 
          centerline of pump impeller shaft, in psia.

    F.1.2 The equipment accuracy requirements specified in section B, 
``Measurement Equipment,'' of this appendix also apply to this section 
F, as applicable.
    F.1.2.1 All measurements of head (gauge pressure), flow, and water 
temperature must be taken at the pump suction inlet and all head 
measurements must be normalized back to the centerline of the pump 
impeller shaft in accordance with section A.3.1.3.1 of HI 40.6-2014-B 
(incorporated by reference, see Sec. 431.463).
    F.1.3 All tests must be conducted with clear water that meets the 
requirements adopted in section C.3 of this appendix.
    F.1.4 In section C.3.4, ``Self-priming capability test method,'' of 
NSF/ANSI 50-2015 (incorporated by reference, see Sec. 431.463), ``the 
elapsed time to steady discharge gauge reading or full discharge flow'' 
is determined when the changes in head and flow, respectively, are 
within the tolerance values specified in table 40.6.3.2.2, ``Permissible 
amplitude of fluctuation as a percentage of mean value of quantity being 
measured at any test point,'' of HI 40.6-2014-B (incorporated by 
reference, see Sec. 431.463). The measured priming time (MPT) is 
determined as the point in time when the stabilized load point is first 
achieved, not when stabilization is determined. In addition, the true 
priming time (TPT) is equivalent to the MPT.
    F.1.5 The maximum true priming time for each test run must not 
exceed 10.0 minutes. Disregard section C.3.5 of NSF/ANSI 50-2015 
(incorporated by reference, see Sec. 431.463).

                  G. Optional Testing and Calculations

    G.1 Energy Factor. When making representations regarding the EF of 
dedicated-purpose pool pumps, determine EF on one of four system curves 
(A, B, C, or D) and at any given speed (s) according to the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR07AU17.015

Where:

EFX,s = the energy factor on system curve X at speed s in gal/Wh;
X = one of four possible system curves (A, B, C, or D), as defined in 
          section G.1.1 of this appendix;
s = the tested speed, in rpm;
QX,s = flow rate measured on system curve X at speed s in gpm; and
PX,s = driver power input to the motor (or controls, if present) on 
          system curve X at speed s in watts.

    G.1.1 System Curves. The energy factor may be determined at any 
speed (s) and on any of the four system curves A, B, C, and/or D 
specified in the Table 3:

motor model, according to the testing and calculations described in 
sections A, B, C, D, and E of this appendix. Alternatively, each 
replacement DPPP motor may be tested with the most consumptive 
dedicated-purpose pool pump bare pump for which it is advertised to be 
paired, as stated in the manufacturer's literature for that replacement 
DPPP motor model. If a replacement DPPP motor is not advertised to be 
paired with any specific dedicated-purpose pool pump bare pumps, test 
with the most consumptive dedicated-purpose pool pump bare pump 
available.

 Sec. Appendix C to Subpart Y of Part 431--Uniform Test Method for the 
    Measurement of Energy Efficiency of Dedicated-Purpose Pool Pumps

    Note: Any representations made on or after July 19, 2021, with 
respect to the energy use or efficiency of dedicated-purpose pool pumps 
subject to testing pursuant to 10 CFR 431.464(b) must be made in 
accordance with the results of testing pursuant to this appendix.

           I. Test Procedure for Dedicated-Purpose Pool Pumps

                               A. General

    A.1 Test Method. To determine the weighted energy factor (WEF) for 
dedicated-purpose pool pumps, perform ``wire-to-water'' testing in 
accordance with HI 40.6-2014-B, except section 40.6.4.1, ``Vertically 
suspended pumps''; section 40.6.4.2, ``Submersible pumps''; section 
40.6.5.3, ``Test report''; section 40.6.5.5, ``Test conditions''; 
section 40.6.5.5.2, ``Speed of rotation during testing''; section 
40.6.6.1, ``Translation of test results to rated speed of rotation''; 
section 40.6.6.2, ``Pump efficiency''; section 40.6.6.3, ``Performance 
curve''; section A.7, ``Testing at temperatures exceeding 30 [deg]C 
(86[emsp14] [deg]F)''; and appendix B, ``Reporting of test results''; 
(incorporated by reference, see Sec. 431.463) with the modifications 
and additions as noted throughout the provisions below. Do not use the 
test points specified in section 40.6.5.5.1, ``Test procedure'' of HI 
40.6-2014-B and instead use those test points specified in section D.3 
of this appendix for the applicable dedicated-purpose pool pump variety 
and speed configuration. When determining overall efficiency, best 
efficiency point, or other applicable pump energy performance 
information, section 40.6.5.5.1, ``Test procedure''; section 40.6.6.2, 
``Pump efficiency''; and section 40.6.6.3, ``Performance curve'' must be 
used, as applicable. For the purposes of applying this appendix, the 
term ``volume per unit time,'' as defined in section 40.6.2, ``Terms and 
definitions,'' of HI 40.6-2014-B shall be deemed to be synonymous with 
the term ``flow rate'' used throughout that standard and this appendix .
    A.2 Calculations and Rounding. All terms and quantities refer to 
values determined in accordance with the procedures set forth in this 
appendix for the rated pump. Perform all calculations using raw measured 
values without rounding. Round WEF, maximum head, vertical lift, and 
true priming time values to the tenths place (i.e., 0.1) and rated 
hydraulic horsepower to the thousandths place (i.e., 0.001). Round all 
other reported values to the hundredths place unless otherwise 
specified.

                        B. Measurement Equipment

    B.1 For the purposes of measuring flow rate, speed of rotation, 
temperature, and pump power output, the equipment specified in HI 40.6-
2014-B Appendix C (incorporated by reference, see Sec. 431.463) 
necessary to measure head, speed of rotation, flow rate, and temperature 
must be used and must comply with the stated accuracy requirements in HI 
40.6-2014-B Table 40.6.3.2.3, except as specified in sections B.1.1 and 
B.1.2 of this appendix. When more than one instrument is used to measure 
a given parameter, the combined accuracy, calculated as the root sum of 
squares of individual instrument accuracies, must meet the specified 
accuracy requirements.
    B.1.1 Electrical measurement equipment for determining the driver 
power input to the motor or controls must be capable of measuring true 
root mean squared (RMS) current, true RMS voltage, and real power up to 
the 40th harmonic of fundamental supply source frequency, and have a 
combined accuracy of 2.0 percent of the measured 
value at the fundamental supply source frequency.
    B.1.2 Instruments for measuring distance (e.g., height above the 
reference plane or water level) must be accurate to and have a 
resolution of at least 0.1 inch.
    B.2 Calibration. Calibration requirements for instrumentation are 
specified in appendix D of HI 40.6-2014-B (incorporated by reference, 
see Sec. 431.463). Historical calibration data may be used to justify 
time periods up to three times longer than those specified in table D.1 
of HI 40.6-2014-B provided the supporting historical data shows 
maintenance of calibration of the given instrument up to the selected 
extended calibration interval on at least two unique occasions, based on 
the interval specified in HI 40.6-2014-B.

                    C. Test Conditions and Tolerances

    C.1 Pump Specifications. Conduct testing at full impeller diameter 
in accordance with the test conditions, stabilization requirements, and 
specifications of HI 40.6-2014-B

section 40.6.3, ``Pump efficiency testing''; section 40.6.4, 
``Considerations when determining the efficiency of a pump''; section 
40.6.5.4 (including appendix A), ``Test arrangements''; and section 
40.6.5.5, ``Test conditions'' (incorporated by reference, see Sec. 
431.463).
    C.2 Power Supply Requirements. The following conditions also apply 
to the mains power supplied to the DPPP motor or controls, if any:
    (1) Maintain the voltage within 5 percent of 
the rated value of the motor,
    (2) Maintain the frequency within 1 percent of 
the rated value of the motor,
    (3) Maintain the voltage unbalance of the power supply within 3 percent of the value with which the motor was rated, 
and
    (4) Maintain total harmonic distortion below 12 percent throughout 
the test.
    C.3 Test Conditions. Testing must be carried out with water that is 
between 50 and 107 [deg]F with less than or equal to 15 nephelometric 
turbidity units (NTU).
    C.4 Tolerances. For waterfall pumps, multi-speed self-priming and 
non-self-priming pool filter pumps, and variable-speed self-priming and 
non-self-priming pool filter pumps all measured load points must be 
within 2.5 percent of the specified head value and 
comply with any specified flow values or thresholds. For all other 
dedicated-purpose pool pumps, all measured load points must be within 
the greater of 2.5 percent of the specified flow 
rate values or 0.5 gpm and comply with any 
specified head values or thresholds.

                  D. Data Collection and Stabilization

    D.1 Damping Devices. Use of damping devices, as described in section 
40.6.3.2.2 of HI 40.6-2014-B (incorporated by reference, see Sec. 
431.463), are only permitted to integrate up to the data collection 
interval used during testing.
    D.2 Stabilization. Record data at any tested load point only under 
stabilized conditions, as defined in HI 40.6-2014-B section 40.6.5.5.1 
(incorporated by reference, see Sec. 431.463), where a minimum of two 
measurements are used to determine stabilization.
    D.3 Test Points. Measure the flow rate in gpm, pump total head in 
ft, the driver power input in W, and the speed of rotation in rpm at 
each load point specified in Table 1 of this appendix for each DPPP 
variety and speed configuration:

               F. Determination of Self-Priming Capability

    F.1 Test Method. Determine the vertical lift and true priming time 
of non-self-priming pool filter pumps and self-priming pool filter pumps 
that are not already certified as self-priming under NSF/ANSI 50-2015 
(incorporated by reference, see Sec. 431.463) by testing such pumps 
pursuant to section C.3 of appendix C of NSF/ANSI 50-2015, except for 
the modifications and exceptions listed in the following sections F.1.1 
through F.1.5 of this appendix:
    F.1.1 Where section C.3.2, ``Apparatus,'' and section C.3.4, ``Self-
priming capability test method,'' of NSF/ANSI 50-2015 (incorporated by 
reference, see Sec. 431.463) state that the ``suction line must be 
essentially as shown in annex C, figure C.1;'' the phrase ``essentially 
as shown in Annex C, figure C.1'' means:
    (1) The centerline of the pump impeller shaft is situated a vertical 
distance equivalent to the specified vertical lift (VL), calculated in 
accordance with section F.1.1.1. of this appendix, above the water level 
of a water tank of sufficient volume as to maintain a constant water 
surface level for the duration of the test;
    (2) The pump draws water from the water tank with a riser pipe that 
extends below the water level a distance of at least 3 times the riser 
pipe diameter (i.e., 3 pipe diameters);
    (3) The suction inlet of the pump is at least 5 pipe diameters from 
any obstructions, 90[deg] bends, valves, or fittings; and
    (4) The riser pipe is of the same pipe diameter as the pump suction 
inlet.
    F.1.1.1 The vertical lift (VL) must be normalized to 5.0 feet at an 
atmospheric pressure of 14.7 psia and a water density of 62.4 lb/ft\3\ 
in accordance with the following equation:
[GRAPHIC] [TIFF OMITTED] TR07AU17.020

Where:

VL = vertical lift of the test apparatus from the waterline to the 
          centerline of the pump impeller shaft, in ft;
[rho]test = density of test fluid, in lb/ft\3\; and
Pabs,test = absolute barometric pressure of test apparatus location at 
          centerline of pump impeller shaft, in psia.

    F.1.2 The equipment accuracy requirements specified in section B, 
``Measurement Equipment,'' of this appendix also apply to this section 
F, as applicable.
    F.1.2.1 All measurements of head (gauge pressure), flow, and water 
temperature must be taken at the pump suction inlet and all head 
measurements must be normalized back to the centerline of the pump 
impeller shaft in accordance with section A.3.1.3.1 of HI 40.6-2014-B 
(incorporated by reference, see Sec. 431.463).
    F.1.3 All tests must be conducted with clear water that meets the 
requirements adopted in section C.3 of this appendix.
    F.1.4 In section C.3.4, ``Self-priming capability test method,'' of 
NSF/ANSI 50-2015 (incorporated by reference, see Sec. 431.463), ``the 
elapsed time to steady discharge gauge reading or full discharge flow'' 
is determined when the changes in head and flow, respectively, are 
within the tolerance values specified in table 40.6.3.2.2, ``Permissible 
amplitude of fluctuation as a percentage of mean value of quantity being 
measured at any test point,'' of HI 40.6-2014-B (incorporated by 
reference, see Sec. 431.463). The measured priming time (MPT) is 
determined as the point in time when the stabilized load point is first 
achieved, not when stabilization is determined. In addition, the true 
priming time (TPT) is equivalent to the MPT.
    F.1.5 The maximum true priming time for each test run must not 
exceed 10.0 minutes.

WEF for replacement DPPP motors, test each replacement DPPP motor paired 
with each dedicated-purpose pool pump bare pump for which the 
replacement DPPP motor is advertised to be paired, as stated in the 
manufacturer's literature for that replacement DPPP motor model, 
according to the testing and calculations described in sections A, B, C, 
D, and E of this appendix. Alternatively, each replacement DPPP motor 
may be tested with the most consumptive dedicated-purpose pool pump bare 
pump for which it is advertised to be paired, as stated in the 
manufacturer's literature for that replacement DPPP motor model. If a 
replacement DPPP motor is not advertised to be paired with any specific 
dedicated-purpose pool pump bare pumps, test with the most consumptive 
dedicated-purpose pool pump bare pump available.

Sec. 434.99  Explanation of numbering system for codes.

    (a) For purposes of this part, a derivative of two different 
numbering systems will be used.
    (1) For the purpose of designating a section, the system employed in 
the Code of Federal Regulations (CFR) will be employed. The number 
``434'' which signifies part 434 in chapter II of Title 10, Code of 
Federal Regulations, is used as a prefix for all section headings. The 
suffix is a two or three digit section number. For example the lighting 
section of the standards is designated Sec. 434.401.
    (2) Within each section, a numbering system common to many national 
voluntary consensus standards is used. A decimal system is used to 
denote paragraphs and subparagraphs within a section. For example, in 
Sec. 434.401, ``401.2.1'' refers to subsection 401, paragraph 2, 
subparagraph 1.
    (b) The hybrid numbering system is used for two purposes:
    (1) The use of the Code of Federal Regulations' numbering system 
allows the researcher using the CFR easy access to the standards.
    (2) The use of the second system allows the builder, designer, 
architect or engineer easy access because they are familiar to this 
system numbering. This system was chosen because of its commonality 
among the building industry.



            Subpart A_Administration and Enforcement_General



Sec. 434.100  Purpose.

    The provisions of this part provide minimum standards for energy 
efficiency for the design of new Federal commercial and multi-family 
high rise residential buildings, for which design for construction began 
before January 3, 2007. The performance standards are designed to 
achieve the maximum practicable improvements in energy efficiency and 
increases in the use of non-depletable sources of energy. This rule is 
based upon the ASHRAE/IESNA Standard 90.1-1989 and addenda b, c, d,

    401.3 Lighting Power Allowance. The lighting system shall meet the 
provisions of subsections 401.3.1 through 401.3.5.
    401.3.1 Building Exteriors. The total connected exterior lighting 
power for the building, or a facility containing multiple buildings, 
shall not exceed the total exterior lighting power allowance, which is 
the sum of the individual allowances determined from Table 401.3.1. The 
individual allowances are determined by multiplying the specific area or 
length of each area description times the allowance for that area. 
Exceptions are as follows: Lighting for outdoor manufacturing or 
processing facilities, commercial greenhouses, outdoor athletic 
facilities, public monuments, designated high-risk security areas, 
signs, retail storefronts, exterior enclosed display windows, and 
lighting specifically required by local ordinances and regulations.

    401.3.1.1 Trade-offs of exterior lighting budgets among exterior 
areas shall be allowed provided the total connected lighting power of 
the exterior area does not exceed the exterior lighting power allowance. 
Trade-offs between interior lighting power allowances and exterior 
lighting power allowances shall not be allowed.
    401.3.2 Building interiors. The total connected interior lighting 
power for a building, including adjustments in accordance with 
subsection 401.3.3, shall not exceed the total interior lighting power 
allowance explained in this paragraph. Using Table 401.3.2a, multiply 
the interior lighting power allowance value by the gross lighted area of 
the most appropriate building or space activity. For multi-use 
buildings, using Table 401.3.2a, select the interior power allowance 
value for each activity using the column for the gross lighted area of 
the whole building and multiply it by the associated gross area for that 
activity. The interior lighting power allowance is the sum of all the 
wattages for each area/activity. Using Table 401.3.2b, c, or d, multiply 
the interior lighting power allowance values of each individual area/
activity by the area of the space and by the area factor from Figure 
401.3.2e, based on the most appropriate area/activity provided. The 
interior lighting power allowance is the sum of the wattages for each 
individual space. When over 20% of the building's tasks or interior 
areas are undefined, the most appropriate value for that building from 
Table 401.3.2a shall be used for the undefined spaces. Exceptions are as 
follows:
    (a) Lighting power that is an essential technical element for the 
function performed in theatrical, stage, broadcasting, and similar uses.
    (b) Specialized medical, dental, and research lighting.
    (c) Display lighting for exhibits in galleries, museums, and 
monuments.
    (d) Lighting solely for indoor plant growth (between the hours of 
10:00 pm and 6:00 am).
    (e) Emergency lighting that is automatically off during normal 
building operation.
    (f) High-risk security areas.

[[Page 1057]]

    (g) Spaces specifically designed for the primary use by the 
physically impaired or aged.
    (h) Lighting in dwelling units.
    401.3.2.1 Trade-offs of the interior lighting power budgets among 
interior spaces shall be allowed provided the total connected lighting 
power within the building does not exceed the interior lighting power 
allowance. Trade-offs between interior lighting power allowances and 
exterior lighting power allowances shall not be allowed.
    401.3.2.2 Building/Space Activities. Definitions of buildings/space 
activity as they apply to Table 401.3.2a are as follows. These 
definitions are necessary to characterize the activities for which 
lighting is provided. They are applicable only to Table 401.3.2a. They 
are not intended to be used elsewhere in place of building use group 
definitions provided in the Building Code. They are not included in 
Sec. 434.201, ``Definitions,'' to avoid confusion with ``Occupancy Type 
Categories.''
    (a) Food service, fast food, and cafeteria: This group includes 
cafeterias, hamburger and sandwich stores, bakeries, ice cream parlors, 
cookie stores, and all other kinds of retail food service establishments 
in which customers are generally served at a counter and their direct 
selections are paid for and taken to a table or carried out.
    (b) Garages: This category includes all types of parking garages, 
except for service or repair areas.
    (c) Leisure dining and bar: This group includes cafes, diners, bars, 
lounges, and similar establishments where orders are placed with a wait 
person.
    (d) Mall concourse, multi-store service: This group includes the 
interior of multifunctional public spaces, such as shopping center 
malls, airports, resort concourses and malls, entertainment facilities, 
and related types of buildings or spaces.
    (e) Offices: This group includes all kinds of offices, including 
corporate and professional offices, office/laboratories, governmental 
offices, libraries, and similar facilities, where paperwork occurs.
    (f) Retail: A retail store, including departments for the sale of 
accessories, clothing, dry goods, electronics, and toys, and other types 
of establishments that display objects for direct selection and purchase 
by consumers. Direct selection means literally removing an item from 
display and carrying it to the checkout or pick-up at a customer service 
facility.
    (g) Schools: This category, subdivided by pre-school/elementary, 
junior high/high school, and technical/vocational, includes public and 
private educational institutions, for children or adults, and may also 
include community centers, college and university buildings, and 
business educational centers.
    (h) Service establishment: A retail-like facility, such as watch 
repair, real estate offices, auto and tire service facilities, parts 
departments, travel agencies and similar facilities, in which the 
customer obtains services rather than the direct selection of goods.
    (i) Warehouse and storage: This includes all types of support 
facilities, such as warehouses, barns, storage buildings, shipping/
receiving buildings, boiler or mechanical buildings, electric power 
buildings, and similar buildings where the primary visual task is large

Ar = space area (ft\2\).

If AF <1.0 use 1.0; if AF 1.8 use 1.8

    401.3.3 Lighting Power Control Credits. The interior connected 
lighting power determined in accordance with Sec. 434.401.3.2 can be 
decreased for luminaries that are automatically controlled for 
occupancy, daylight, lumen maintenance, or programmable timing. The 
adjusted interior connected lighting power shall be determined by 
subtracting the sum of all lighting power control credits from the 
interior connected lighting power. Using Table 401.3.3, the lighting 
power control credit equals the power adjustment factor times the 
connected lighting power of the controlled lighting. The lighting power 
adjustment shall be applied with the following limitations:
    (a) It is limited to the specific area controlled by the automatic 
control device.
    (b) Only one lighting power adjustment may be used for each building 
space or luminaire, and 50 percent or more of the controlled luminaire 
shall be within the applicable space.
    (c) Controls shall be installed in series with the lights and in 
series with all manual switching devices.
    (d) When sufficient daylight is available, daylight sensing controls 
shall be capable of reducing electrical power consumption for lighting 
(continuously or in steps) to 50 percent or less of maximum power 
consumption.
    (e) Daylight sensing controls shall control all luminaires to which 
the adjustment is applied and that direct a minimum of 50 percent of 
their light output into the daylight zone.
    (f) Programmable timing controls shall be able to program different 
schedules for occupied and unoccupied days, be readily accessible for 
temporary override with automatic return to the original schedule, and 
keep time during power outages for at least four hours.

    401.3.4.1 Type of Lighting Controls. All lighting systems shall have 
controls, with the exception of emergency use or exit lighting.
    401.3.4.2 Number of Manual Controls. Spaces enclosed by walls or 
ceiling-high partitions shall have a minimum of one manual control (on/
off switch) for lighting in that space. Additional manual controls shall 
be provided for each task location or for each group of task locations 
within an area of 450 ft\2\ or less. For spaces with only one lighting 
fixture or with a single ballast, one manual control is required. 
Exceptions are as follows:
    401.3.4.2.1 Continuous lighting for security;
    401.3.4.2.2 Systems in which occupancy sensors, local programmable 
timers, or three-level (including OFF) step controls or preset dimming 
controls are substituted for manual controls at the rate of one for 
every two required manual controls, providing at least one control is 
installed for every 1500 watts of power.
    401.3.4.2.3 Systems in which four-level (including OFF) step 
controls or preset dimming controls or automatic or continuous dimming 
controls are substituted for manual controls at a rate of one for every 
three required manual controls, providing at least one control is 
installed for every 1500 watts of power.
    401.3.4.2.4 Spaces that must be used as a whole, such as public 
lobbies, retail stores, warehouses, and storerooms.
    401.3.4.3 Multiple Location Controls. Manual controls that operate 
the same load from multiple locations must be counted as one manual 
control.
    401.3.4.4 Control Accessibility. Lighting controls shall be readily 
accessible from within the space controlled. Exceptions are as follows: 
Controls for spaces that are to be used as a whole, automatic controls,

    402.1.1 Material Properties. Information on thermal properties, 
building envelope system performance, and component heat transfer shall 
be obtained from RS-4. When the information is not available from RS-4, 
(incorporated by reference, see Sec. 434.701) the data shall be 
obtained from manufacturer's information or laboratory or field test 
measurements using RS-5, RS-6, RS-7, or RS-8 (incorporated by reference, 
see Sec. 434.701).
    402.1.1.1 The shading coefficient (SC) for fenestration shall be 
obtained from RS-4 (incorporated by reference, see Sec. 434.701) or 
from manufacturer's test data. The shading coefficient of the 
fenestration, including both internal and external shading devices, is 
SCX and excludes the effect of external shading projections, 
which are calculated separately. The shading coefficient used for 
louvered shade screens shall be determined using a profile angle of 30 
degrees as found in Table 41, Chapter 27 of RS-4 (incorporated by 
reference, see Sec. 434.701).
    402.1.2 Thermal Performance Calculations. The overall thermal 
transmittance of the building envelope shall be calculated in accordance 
with Equation 402.1.2:
[GRAPHIC] [TIFF OMITTED] TR06OC00.022

Where:

Uo = the area-weighted average thermal transmittance of the 
          gross area of the building envelope; i.e., the exterior wall 
          assembly including fenestration and doors, the roof and 
          ceiling assembly, and the floor assembly, Btu/
          (h[middot]ft\2\[middot][deg]F)
Ao = the gross area of the building envelope, ft\2\
Ui = the thermal transmittance of each individual path of the 
          building envelope, i.e., the opaque portion or the 
          fenestration, Btu/(h[middot]ft\2\[middot][deg]F)
Ui = 1/Ri (where Ri is the total 
          resistance to heat flow of an individual path through the 
          building envelope)
Ai = the area of each individual element of the building 
          envelope, ft\2\

    The thermal transmittance of each component of the building envelope 
shall be determined with due consideration of all major series and 
parallel heat flow paths through the elements of the component and film 
coefficients and shall account for any compression of insulation. The 
thermal transmittance of opaque elements of assemblies shall be 
determined using a series path procedure with corrections for the 
presence of parallel paths within an element of the envelope assembly 
(such as wall cavities with parallel paths through insulation and 
studs). The thermal performance of adjacent ground in below-grade 
applications shall be excluded from all thermal calculations.
    402.1.2.1 Envelope Assemblies Containing Metal Framing. The thermal 
transmittance of the envelope assembly containing metal framing shall be 
determined from one of three methods:
    (a) Laboratory or field test measurements based on RS-5, RS-6, RS-7, 
or RS-8 (incorporated by reference, see Sec. 434.701).
    (b) The zone method described in Chapter 22 of RS-4 (incorporated by 
reference, see Sec. 434.701) and the formulas on page 22.10.
    (c) For metal roof trusses or metal studs covered by Tables 
402.1.2.1a and b, the total resistance of the series path shall be 
calculated in accordance with the following Equations:
[GRAPHIC] [TIFF OMITTED] TR06OC00.023

Where:

Rt = the total resistance of the envelope assembly
Ri = the resistance of the series elements (for i = 1 to n) 
          excluding the parallel path element(s)
Re = the equivalent resistance of the element containing the 
          parallel path (R-value of

[[Page 1064]]

          equivalent resistances shall be taken from Tables 402.1.2.1a 
          or b.

[Use 3.0 W/ft \2\ for HDD65 <3000, 2.25 W/ft \2\ for 3000 6000.]
    (b) When more than one condition exists, area weighted averages 
shall be used. This requirement shall apply to all thermal 
transmittances, shading coefficients, projection factors, and internal 
load densities rounded to the same number of decimal places as shown in 
the respective table.
    402.4.1.1 Opaque Walls. The weighted average thermal transmittance 
(U-value) of opaque wall elements shall be less than the values in Table 
402.4.1.1. For mass walls (HC =5), criteria are presented for 
low and high window/wall ratios and the criteria shall be determined by 
interpolating between these values for the window/wall ratio of the 
building.
    402.4.1.2 Fenestration. The design of the fenestration shall meet 
the criteria of Table 402.4.1.2. When the fenestration columns labeled 
``Perimeter Daylighting'' are used, automatic daylighting controls shall 
be installed in the perimeter daylighted zones of the building. These 
daylighting controls shall be capable of reducing electric lighting 
power to at least 50% of full power. Only those shading or lighting 
controls for perimeter daylighting that are shown on the plans shall be 
considered. The column labeled ``VLT = SC'' shall be used 
only when the shading coefficient of the glass is less than its visible 
light transmittance.

    403.1.1 Where multiple rating conditions and/or performance 
requirements are provided, the equipment shall satisfy all stated 
requirements.
    403.1.2 Equipment used to provide water heating functions as part of 
a combination integrated system shall satisfy all stated requirements 
for the appropriate space heating or cooling category.
    403.1.3 The equipment efficiency shall be supported by data 
furnished by the manufacturer or shall be certified under a nationally 
recognized certification program or rating procedure.
    403.1.4 Where components, such as indoor or outdoor coils, from 
different manufacturers are used, the system designer shall specify 
component efficiencies whose combined efficiency meets the standards 
herein.
    403.2 HVAC Systems.
    403.2.1 Load Calculations. Heating and cooling system design loads 
for the purpose of sizing systems and equipment shall be determined in 
accordance with the procedures described in RS-1 (incorporated by 
reference, see Sec. 434.701) using the design parameters specified in 
subpart C of this part.
    403.2.2 Equipment and System Sizing. Heating and cooling equipment 
and systems shall be sized to provide no more than the loads calculated 
in accordance with subsection 403.2.1. A single piece of equipment 
providing both heating and cooling must satisfy this provision for one 
function with the other function sized as small as possible to meet the 
load, within available equipment options. Exceptions are as follows:

[[Page 1074]]

    (a) When the equipment selected is the smallest size needed to meet 
the load within available options of the desired equipment line.
    (b) Standby equipment provided with controls and devices that allow 
such equipment to operate automatically only when the primary equipment 
is not operating.
    (c) Multiple units of the same equipment type with combined 
capacities exceeding the design load and provided with controls that 
sequence or otherwise optimally control the operation of each unit based 
on load.
    403.2.3 Separate Air Distribution System. Zones with special process 
temperature and/or humidity requirements shall be served by air 
distribution systems separate from those serving zones requiring only 
comfort conditions or shall include supplementary provisions so that the 
primary systems may be specifically controlled for comfort purposes 
only. Exceptions: Zones requiring only comfort heating or comfort 
cooling that are served by a system primarily used for process 
temperature and humidity control need not be served by a separate system 
if the total supply air to these comfort zones is no more than 25% of 
the total system supply air or the total conditioned floor area of the 
zones is less than 1000 ft2.
    403.2.4 Ventilation and Fan System Design. Ventilation systems shall 
be designed to be capable of reducing the supply of outdoor air to the 
minimum ventilation rates required by Section 6.1.3 of RS-41 
(incorporated by reference, see Sec. 434.701) through the use of return 
ducts, manually or automatically operated control dampers, fan volume 
controls, or other devices. Exceptions are as follows: Minimum outdoor 
air rates may be greater if:
    (a) Required to make up air exhausted for source control of 
contaminants such as in a fume hood.
    (b) Required by process systems.
    (c) Required to maintain a slightly positive building pressure. For 
this purpose, minimum outside air intake may be increased up to no 
greater than 0.30 air changes per hour in excess of exhaust quantities.
    403.2.4.1 Ventilation controls for variable or high occupancy areas. 
Systems with design outside air capacities greater than 3,000 cfm 
serving areas having an average design occupancy density exceeding 100 
people per 1,000 ft\2\ shall include means to automatically reduce 
outside air intake to the minimum values required by RS-41 (incorporated 
by reference, see Sec. 434.701) during unoccupied or low-occupancy 
periods. Outside air shall not be reduced below 0.14 cfm/ft\2\. Outside 
air intake shall be controlled by one or more of the following:
    (a) A clearly labeled, readily accessible bypass timer that may be 
used by occupants or operating personnel to temporarily increase minimum 
outside air flow up to design levels.
    (b) A carbon dioxide (CO2) control system having sensors 
located in the spaces served, or in the return air from the spaces 
served, capable of maintaining space CO2 concentrations below 
levels recommended by the manufacturer, but no fewer than one sensor per 
25,000 ft\2\ of occupied space shall be provided.
    (c) An automatic timeclock that can be programmed to maintain 
minimum outside air intake levels commensurate with scheduled occupancy 
levels.
    (d) Spaces equipped with occupancy sensors.

    404.1.1 Testing Electric and Oil Storage Water Heaters for Standby 
Loss.
    (a) When testing an electric storage water heater, the procedures of 
Z21.10.3-1990 (RS-39, incorporated by reference, see Sec. 434.701), 
Section 2.9, shall be used. The electrical supply voltage shall be 
maintained with 1% of the center of the voltage 
range specified on the water heater nameplate. Also, when needed for 
calculations, the thermal efficiency (Et) shall be 98%.

[[Page 1081]]

When testing an oil-fired water heater, the procedures of Z21.10.3-1990 
(RS-39 incorporated by reference, see Sec. 434.701), Sections 2.8 and 
2.9, shall be used.
    (b) The following modifications shall be made: A vertical length of 
flue pipe shall be connected to the flue gas outlet of sufficient height 
to establish the minimum draft specified in the manufacturer's 
installation instructions. All measurements of oil consumption shall be 
taken by instruments with an accuracy of 1% or 
better. The burner rate shall be adjusted to achieve an hourly Btu input 
rate within 2% of the manufacturer's specified 
input rate with the CO2 reading as specified by the 
manufacturer with smoke no greater than 1 and the fuel pump pressure 
within 1% of the manufacturer's specification.
    404.1.2 Unfired Storage Tanks. The heat loss of the tank surface 
area Btu/(h[middot]ft\2\) shall be based on an 80 [deg]F water-air 
temperature difference.
    404.1.3 Storage Volume Symbols in Table 404.1. The symbol ``V'' is 
the rated storage volume in gallons as specified by the manufacturer. 
The symbol ``VT'' is the storage volume in gallons as 
measured during the test to determine the standby loss. VT 
may differ from V, but it is within tolerances allowed by the applicable 
Z21 and Underwriters Laboratories standards. Accordingly, for the 
purpose of estimating the standby loss requirement using the rated 
volume shown on the rating plate, VT should be considered as 
no less than 0.95V for gas and oil water heaters and no less than 0.90V 
for electric water heaters.
    404.1.4 Electric Water Heaters. In applications where water 
temperatures not greater than 145 [deg]F are required, an economic 
evaluation shall be made on the potential benefit of using an electric 
heat pump water heater(s) instead of an electric resistance water 
heater(s). The analysis shall compare the extra installed costs of the 
heat pump unit with the benefits in reduced energy costs (less increased 
maintenance costs) over the estimated service life of the heat pump 
water heater. Exceptions are as follows: Electric water heaters used in 
conjunction with site-recovered or site-solar energy sources that 
provide 50% or more of the water heating load or off-peak heating with 
thermal storage.
    404.2 Service Hot Water Piping Insulation. Circulating system piping 
and noncirculating systems without heat traps, the first eight feet of 
outlet piping from a constant-temperature noncirculating storage system, 
and the inlet pipe between the storage tank and a heat trap in a 
noncirculating storage system shall meet the provisions of subsection 
403.2.9.
    404.2.1 Vertical risers serving storage water heaters not having an 
integral heat trap and serving a noncirculating system shall have heat 
traps on both the inlet and outlet piping as close as practical to the 
water heater.
    404.3 Service Water Heating System Controls. Temperature controls 
that allow for storage temperature adjustment from 110 [deg]F to a 
temperature compatible with the intended use shall be provided in 
systems serving residential dwelling units and from 90 [deg]F for other 
systems. When designed to maintain usage temperatures in hot water 
pipes, such as circulating hot water systems or heat trace, the system 
shall be equipped with automatic time switches or other controls that 
can be set to turn off the system.
    404.3.1 The outlet temperature of lavatory faucets in public 
facility restrooms shall be limited to 110 [deg]F.
    404.4 Water Conservation. Showerheads and lavatory faucets must meet 
the requirements of 10 CFR 430.32 (o)-(p).
    404.4.1 Lavatory faucets in public facility restrooms shall be 
equipped with a foot switch, occupancy sensor, or similar device or, in 
other than lavatories for physically handicapped persons, limit water 
delivery to 0.25 gal/cycle.
    404.5 Swimming Pools. All pool heaters shall be equipped with a 
readily accessible on-off switch.
    404.5.1 Time switches shall be installed on electric heaters and 
pumps. Exceptions are as follows:
    (a) Pumps required to operate solar or heat recovery pool heating 
systems.
    (b) Where public health requirements require 24-hour pump operation.
    404.5.2 Heated swimming pools shall be equipped with pool covers. 
Exception: When over 70% of the annual energy for heating is obtained 
from a

[[Page 1082]]

site-recovered or site-solar energy source.
    404.6 Combined Service Water Heating and Space Heating Equipment. A 
single piece of equipment shall not be used to provide both space 
heating and service water heating. Exceptions are as follows:
    (a) The energy input or storage volume of the combined boiler or 
water heater is less than twice the energy input or storage volume of 
the smaller of the separate boilers or water heaters otherwise required 
or
    (b) The input to the combined boiler is less than 150,000 Btuh.



          Subpart E_Building Energy Cost Compliance Alternative



Sec. 434.501  General.

    501.1 Subpart E permits the use of the Building Energy Cost 
Compliance Alternative as an alternative to many elements of subpart D. 
When this subpart is used, it must be used with subpart C and subpart D, 
401.1, 401.2, 401.3.4 and in conjunction with the minimum requirements 
found in subsections 402.1, 402.2, and 402.3., 403.1, 403.2.1-7, 403.2.9 
and 404.
    501.2 Compliance. Compliance under this method requires detailed 
energy analyses of the entire Proposed Design, referred to as the Design 
Energy Consumption; an estimate of annual energy cost for the proposed 
design, referred to as the Design Energy Cost; and comparison against an 
Energy Cost Budget. Compliance is achieved when the estimated Design 
Energy Cost is less than or equal to the Energy Cost Budget. This 
subpart provides instructions for determining the Energy Cost Budget and 
for calculating the Design Energy Consumption and Design Energy Cost. 
The Energy Cost Budget shall be determined through the calculation of 
monthly energy consumption and energy cost of a Prototype or Reference 
Building design configured to meet the requirements of subsections 401 
through 404.
    501.3 Designers are encouraged to employ the Building Energy Cost 
Budget compliance method set forth in this section for evaluating 
proposed design alternatives to using the elements prescribed in subpart 
D. The Building Energy Cost Budget establishes the relative 
effectiveness of each design alternative in energy cost savings, 
providing an energy cost basis upon which the building owner and 
designer may select one design over another. This Energy Cost Budget is 
the highest allowable calculated energy cost for a specific building 
design. Other alternative designs are likely to have lower annual energy 
costs and life cycle costs than those used to minimally meet the Energy 
Cost Budget.
    501.4 The Energy Cost Budget is a numerical reference for annual 
energy cost. It's purpose is to assure neutrality with respect to 
choices such as HVAC system type, architectural design and fuel choice 
by providing a fixed, repeatable budget that is independent of any of 
these choices wherever possible (i.e., for the prototype buildings). The 
Energy Cost Budget for a given building size and type will vary only 
with climate, the number of stories, and the choice of simulation tool. 
The specifications of the prototypes are necessary to assure 
repeatability, but have no other significance. They are not necessarily 
recommended energy conserving practice, or even physically reasonable 
practice for some climates or buildings, but represent a reasonable 
worst case of energy cost resulting from compliance with the provisions 
of subsections 401 through 404.



Sec. 434.502  Determination of the annual energy cost budget.

    502.1 The annual Energy Cost Budgets shall be determined in 
accordance with the Prototype Building Procedure in Sec. 434.503 and 
Sec. 434.504 or the Reference Building Procedure in Sec. 434.505. Both 
methods calculate an annual Energy Cost by summing the 12 monthly Energy 
Cost Budgets. Each monthly Energy Cost Budget is the product of the 
monthly Building Energy Consumption of each type of energy used 
multiplied by the monthly Energy Cost per unit of energy for each type 
of energy used.
    502.2 The Energy Cost Budget shall be determined in accordance with 
Equation 502.2.a as follows:

[[Page 1083]]

Based on:
[GRAPHIC] [TIFF OMITTED] TR06OC00.026

Where:

ECB = The annual Energy Cost Budget
ECBm = The monthly Energy Cost Budget
BECONmi = The monthly Budget Energy Consumption of the 
          ith type of energy
ECOSmi = The monthly Energy Cost, per unit of the 
          ith type of energy

    502.3 The monthly Energy Cost Budget shall be determined using 
current rate schedules or contract prices available at the building site 
for all types of energy purchased. These costs shall include demand 
charges, rate blocks, time of use rates, interruptible service rates, 
delivery charges, taxes, and all other applicable rates for the type, 
location, operation, and size of the proposed design. The monthly Budget 
Energy Consumption shall be calculated from the first day through the 
last day of each month, inclusive.



Sec. 434.503  Prototype building procedure.

    503.1 The Prototype Building procedure shall be used for all 
building types listed below. For mixed-use buildings the Energy Cost 
Budget is derived by allocating the floor space of each building type 
within the floor space of the prototype building. For buildings not 
listed below, the Reference Building procedure of Sec. 434.505 shall be 
used. Prototype buildings include:
    (a) Assembly;
    (b) Office (Business);
    (c) Retail (Mercantile);
    (d) Warehouse (Storage);
    (e) School (Educational);
    (f) Hotel/Motel;
    (g) Restaurant;
    (h) Health/Institutional; and
    (i) Multi-Family.



Sec. 434.504  Use of the prototype building to determine the energy
cost budget.

    504.1 Determine the building type of the Proposed Design using the 
categories in subsection 503.1. Using the appropriate Prototype Building 
characteristics from all of the tables contained in subpart E, the 
building shall be simulated using the same gross floor area and number 
of floors for the Prototype Building as in the Proposed Design.
    504.2 The form, orientation, occupancy and use profiles for the 
Prototype Building shall be fixed as described in subsection 511. 
Envelope, lighting, other internal loads and HVAC systems and equipment 
shall meet the requirements of subsection 301, 401, 402, 403, and 404 
and are standardized inputs.



Sec. 434.505  Reference building method.

    505.1 The Reference Building procedure shall be used only when the 
Proposed Design cannot be represented by one or a combination of the 
Prototype Building listed in subsection 503.1 or the assumptions for the 
Prototype Building in Subsection 510, such as occupancy and use-
profiles, do not reasonably represent the Proposed Design.



Sec. 434.506  Use of the reference building to determine the energy 
cost budget.

    506.1 Each floor shall be oriented in the same manner for the 
Reference Building as in the Proposed Design. The form, gross and 
conditioned floor areas of each floor and the number of floors shall be 
the same as in the Proposed Design. All other characteristics, such as 
lighting, envelope and HVAC systems and equipment, shall meet the 
requirements of subsections 301, 401, 402, 403 and 404.



Sec. 434.507  Calculation procedure and simulation tool.

    507.1 The Prototype or Reference Buildings shall be modeled using 
the

[[Page 1084]]

criteria of subsections 510 and 521. The modeling shall use a climate 
data set appropriate for both the site and the complexity of the energy 
conserving features of the design. ASHRAE Weather Year for Energy 
Calculations (WYEC) data or bin weather data shall be used in the 
absence of other appropriate data.



Sec. 434.508  Determination of the design energy consumption 
and design energy cost.

    508.1 The Design Energy Consumption shall be calculated by modeling 
the Proposed Design using the same methods, assumptions, climate data, 
and simulation tool as were used to establish the Energy Cost Budget, 
except as explicitly stated in 509 through 534. The Design Energy Cost 
shall be calculated per Equation 508.1.
[GRAPHIC] [TIFF OMITTED] TR06OC00.027


Based on:

DECOSm = DECONml x ECOSml + . . . + 
DECONmi x ECOSmi (Equation 508.1.2)

Where:

DECOS = The annual Design Energy Cost
DECOSm = The monthly Design Energy Cost
DECONmi = The monthly Design Energy Consumption of the 
          ith type of energy
ECOSmi = The monthly Energy Cost per unit of the 
          ith type of energy

    The DECONmi shall be calculated from the first day 
through the last day of the month, inclusive.



Sec. 434.509  Compliance.

    509.1 If the Design Energy Cost is less than or equal to the Energy 
Cost Budget, and all of the minimum requirements of subsection 501.2 are 
met, the Proposed Design complies with the standards.



Sec. 434.510  Standard calculation procedure.

    510.1 The Standard Calculation Procedure consists of methods and 
assumptions for calculating the Energy Cost Budget for the Prototype or 
Reference Building and the Design Energy Consumption and Design Energy 
Cost of the Proposed Design. In order to maintain consistency between 
the Energy Cost Budget and the Design Energy Cost, the input assumptions 
to be used are stated below. These inputs shall be used to determine the 
Energy Cost Budget and the Design Energy Consumption.
    510.2 Prescribed assumptions shall be used without variation. 
Default assumptions shall be used unless the designer can demonstrate 
that a different assumption better characterizes the building's energy 
use over its expected life. The default assumptions shall be used in 
modeling both the Prototype or Reference Building and the Proposed 
Design, unless the designer demonstrates clear cause to modify these 
assumptions. Special procedures for speculative buildings are discussed 
in subsection 503. Shell buildings may not use subpart E.



Sec. 434.511  Orientation and shape.

    511.1 The Prototype Building shall consist of the same number of 
stories, and gross and conditioned floor area as the Proposed Design, 
with equal area per story. The building shape shall be rectangular, with 
a 2.5:1 aspect ratio. The long dimensions of the building shall face 
East and West. The fenestration shall be uniformly distributed in 
proportion to exterior wall area. Floor-to-floor height for the 
Prototype Building shall be 13 ft. except for dwelling units in hotels/
motels and multi-family high-rise residential buildings where floor-to-
floor height shall be 9.5 ft.
    511.2 The Reference Building shall consist of the same number of 
stories, and gross floor area for each story as the Proposed Design. 
Each floor shall be oriented in the same manner as the Proposed Design. 
The geometric form shall be the same as the Proposed Design.

[[Page 1085]]



Sec. 434.512  Internal loads.

    512.1 The systems and types of energy specified in this section are 
provided only for purposes of calculating the Energy Cost Budget. They 
are not requirements for either systems or the type of energy to be used 
in the Proposed Design or for calculation of Design Energy Cost.
    512.2 Internal loads for multi-family high-rise residential 
buildings are prescribed in Tables 512.2.a and b, Multi-Family High Rise 
Residential Building Schedules. Internal loads for other building types 
shall be modeled as noted in this subsection.

Sec. 434.513  Occupancy.

    5131 Occupancy schedules are default assumptions. The same 
assumptions shall be made in computing Design Energy Consumption as were 
used in calculating the Energy Cost Budget.
    513.2 Table 513.2.a, Occupancy Density, establishes the density, in 
ft\2\ person of conditioned floor area, to be used for each building 
type. Table 513.2.b, Building Schedule Percentage Multipliers, 
establishes the percentage of total occupants in the building by hour of 
the day for each building type.

Sec. 434.514  Lighting.

    514.1 Interior Lighting Power Allowance (ILPA), for calculating the 
Energy Cost Budget shall be determined from subsection 401.3.2. The 
lighting power used to calculate the Design Energy Consumption shall be 
the actual adjusted power for lighting in the Proposed Design. If the 
lighting controls in the Proposed Design are more effective at saving 
energy than those required by subsection 401.3.1 and 401.3.2, the actual 
installed lighting power shall be used along with the schedules 
reflecting the action of the controls to calculate the Design Energy 
Consumption. This actual installed lighting

power shall not be adjusted by the Power Adjustment Factors listed in 
Table 514.1.

    514.2 Table 513.2.b establishes default assumptions for the 
percentage of the lighting load switched-on in each Prototype or 
Reference Building by hour of the day. These default assumptions can be 
changed when calculating the Energy Cost Budget to provide, for example, 
a 12-hour rather than an 8-hour workday.



Sec. 434.515  Receptacles.

    515.1 Receptacle loads and profiles are default assumptions. The 
same assumptions shall be made in calculating Design Energy Consumption 
as were used in calculating the Energy Cost Budget.
    515.2 Receptacle loads include all general service loads that are 
typical in a building. These loads exclude any process electrical usage 
and HVAC primary or auxiliary electrical usage. Table 515.2, Receptacle 
Power Densities, establishes the density, in W/ft\2\, to be used for 
each building type. The receptacle energy profiles shall be the same as 
the lighting energy profiles in Table 513.2.b. This profile establishes 
the percentage of the receptacle load that is switched on by hour of the 
day and by building type.

Sec. 434.516  Building exterior envelope.

    516.1 Insulation and Glazing. The insulation and glazing 
characteristics of the Prototype and Reference Building envelope shall 
be determined by using the first column under ``Base Case'', with no 
assumed overhangs, for the appropriate Alternate Component Tables (ACP) 
in Table 402.4.1.2, as defined by climate range. The insulation and 
glazing characteristics from this ACP are prescribed assumptions for 
Prototype and Reference Buildings for calculating the Energy Cost 
Budget. In calculating the Design Energy Consumption of the Proposed 
Design, the envelope characteristics of the Proposed Design shall be 
used.
    516.2 Infiltration. For Prototype and Reference Buildings, the 
infiltration assumptions in subsection 516.2.1 shall be prescribed 
assumptions for calculating the Energy Cost Budget and default 
assumptions for the Design Energy Consumption. Infiltration shall impact 
perimeter zones only.
    516.2.1 When the HVAC system is switched ``on,'' no infiltration 
shall be assumed. When the HVAC system is switched ``off,'' the 
infiltration rate for buildings with or without operable windows shall 
be assumed to be 0.038 cfm/ft\2\ of gross exterior wall. Hotels/motels 
and multi-family high-rise residential buildings shall have infiltration 
rates of 0.038 cfm/ft\2\ of gross exterior wall area at all times.
    516.3 Envelope and Ground Absorptivities. For Prototype and 
Reference Buildings, absorptivity assumptions shall be prescribed 
assumptions for computing the Energy Cost Budget and default assumptions 
for computing the Design Energy Consumption. The solar absorptivity of 
opaque elements of the building envelope is assumed to be 70%. The solar 
absorptivity of ground surfaces is assumed to be 80% (20% reflectivity).
    516.4 Window Management. For the Prototype and Reference Building, 
window management drapery assumptions shall be prescribed assumptions 
for setting the Energy Cost Budget. No draperies shall be the default 
assumption for computing the Design Energy Consumption. Glazing is 
assumed to be internally shaded by medium-weight draperies, closed one-
half time. The

[[Page 1093]]

draperies shall be modeled by assuming that one-half the area in each 
zone is draped and one-half is not. If manually-operated draperies, 
shades, or blinds are to be used in the Proposed Design, the Design 
Energy Consumption shall be calculated by assuming they are effective 
over one-half the glazing area in each zone.
    516.5 Shading. For Prototype and Reference buildings and the 
Proposed Design, shading by permanent structures, terrain, and 
vegetation shall be taken into account for computing energy consumption, 
whether or not these features are located on the building site. A 
permanent fixture is one that is likely to remain for the life of the 
Proposed Design.



Sec. 434.517  HVAC systems and equipment.

    517.1 The specifications and requirements for the HVAC systems of 
the Prototype and Reference Buildings shall be those in Table 517.1.1, 
HVAC Systems for Prototype and Reference Buildings. For the calculation 
of the Design Energy Consumption, the HVAC systems and equipment of the 
Proposed Design shall be used.
    517.2 The systems and types of energy presented in Table 517.1.1 are 
assumptions for calculating the Energy Cost Budget. They are not 
requirements for either systems or the type of energy to be used in the 
Proposed Building or for the calculation of the Design Energy Cost.

\1\ Space and Service Water Heating budget calculations shall be made
  using both electricity and natural gas. The Energy Cost Budget shall
  be the lower of these two calculations. If natural gas is not
  available at the rate, electricity and 2 fuel oil shall be used for
  the budget calculations.
\2\ The system and energy types presented in this Table are not intended
  as requirements or recommendations for the proposed design. Floor
  areas below are the total conditioned floor areas for the listed
  occupancy type in the building. The number of floors indicated below
  is the total number of occupied floors for the listed occupancy type.

    517.3 HVAC Zones. HVAC zones for calculating the Energy Cost Budget 
of the Prototype or Reference Building shall consist of at least four 
perimeter and one interior zones per floor. Prototype Buildings shall 
have one perimeter zone facing each cardinal direction. The perimeter 
zones of Prototype and Reference Buildings shall be 15 ft in width, or 
one-third the narrow dimension of the building, when this dimension is 
between 30 ft and 45 ft inclusive, or one-half the narrow dimension of 
the building when this dimension is less than 30 ft. Zoning requirements 
shall be a default assumption for calculating the Energy Cost Budget. 
For multi-family high-rise residential

[[Page 1094]]

buildings, the prototype building shall have one zone per dwelling unit. 
The proposed design shall have one zone per unit unless zonal 
thermostatic controls are provided within units; in this case, two zones 
per unit shall be modeled. Building types such as assembly or warehouse 
may be modeled as a single zone if there is only one space.
    517.4 For calculating the Design Energy Consumption, no fewer zones 
shall be used than were in the Prototype and Reference Buildings. The 
zones in the simulation shall correspond to the zones provided by the 
controls in the Proposed Design. Thermally similar zones, such as those 
facing one orientation on different floors, may be grouped together for 
the purposes of either the Design Energy Consumption or Energy Cost 
Budget simulation.

                    Numbered Notes for Table 517.4.1

     HVAC System Descriptions for Prototype and Reference Buildings

    Notes:
    1. For occupancies such as restaurants, assembly and retail which 
are part of a mixed use building which, according to Table 517.4.1, 
includes a central chilled water plant (systems 3, 5, or 6), chilled 
water system type 3 or 5, as indicated in the Table, shall be used.
    2. Constant volume may be used in zones where pressurization 
relationships must be maintained by code. VAV shall be used in all other 
areas, in accordance with Sec. 517.4
    3. Provide run-around heat recovery systems for all fan systems with 
minimum outside air intake greater than 75%. Recovery effectiveness 
shall be 0.60.
    4. If a warehouse is not intended to be mechanically cooled, both 
the Energy Cost Budgets and Design Energy Costs, may be calculated 
assuming no mechanical cooling.
    5. The system listed is for guest rooms only. Areas such as public 
areas and back-of-house areas shall be served by system 4. Other areas 
such as offices and retail shall be served by the systems listed in 
Table 517.4.1 for those occupancy types.
    6. The system listed is for guest rooms only. Areas such as public 
areas and back-of-house areas shall be served by System 5. Other areas 
such as offices and retail shall be served by the systems listed in 
Table 517.4.1.1 for those occupancy types.
    7. System 2 shall be used for Energy Cost Budget calculation except 
in areas with design heating outside air temperatures less than 10 
[deg]F.
    8. Prototype energy budget cost calculations shall be made using 
both electricity and natural gas. If natural gas is not available at the 
site, electricity and 2 fuel oil shall be used. The Energy Cost Budget 
shall be the lower of these results. Alternatively, the Energy Cost 
Budget may be based on the fuel source that minimizes total operating, 
maintenance, equipment, and installation costs for the prototype over 
the building lifetime. Equipment and installation cost estimates shall 
be prepared using professionally recognized cost estimating tools, 
guides, and techniques. The methods of analysis shall conform to those 
of subpart A of 10 CFR part 436. Energy costs shall be based on actual 
costs to the building as defined in this Section.
    9. Design supply air circulation rate shall be based on a supply air 
to room air temperature differences of 20 [deg]F. A higher supply air 
temperature may be used if required to maintain a minimum circulation 
rate of 4.5 air changes per hour or 15 cfm per person at design 
conditions to each zone served by the system. If return fans are 
specified, they shall be sized from the supply fan capacity less the 
required minimum ventilation with outside air, or 75% or the supply air 
capacity, whichever is larger. Except where noted, supply and return 
fans shall be operated continually during occupied hours.
    10. Fan System Energy when included in the efficiency rating of the 
unit as defined in Sec. 403.2.4.3 need not be modeled explicitly for 
this system. The fan shall cycle with calls for heating or cooling.
    11. Chilled water systems shall be modeled using a reciprocating 
chiller for systems with total cooling capacities less than 175 tons, 
and centrifugal chillers for systems

[[Page 1096]]

with cooling capacities of 175 tons or greater. For systems with cooling 
or 600 ton or more, the Energy Cost Budget shall be calculated using two 
centrifugal chillers lead/lag controlled. Chilled water pumps shall be 
sized using a 12 [deg]F temperature rise, from 44 [deg]F to 56 [deg]F 
operating at 65 feed of head and 65% combined impeller and motor 
efficiency. Condenser water pumps shall be sized using a 10 [deg]F 
temperature rise, operating at 60 feet of head and 60% combined impeller 
and motor efficiency. The cooling tower shall be an open circuit, 
centrifugal blower type sized for the larger of 85 [deg]F leaving water 
temperature or 10 [deg]F approach to design wet bulb temperature. The 
tower shall be controlled to provide a 65 [deg]F leaving water 
temperature whenever weather conditions permit, floating up to design 
leaving water temperature at design conditions. Chilled water supply 
temperature shall be reset in accordance with Sec. 434.518.
    12. Hot water system shall include a natural draft fossil fuel or 
electric boiler per Note 8. The hot water pump shall be sized based on a 
30 [deg]F temperature drop, for 18 [deg]F to 150 [deg]F, operating at 60 
feet of head and a combined impeller and motor efficiency of 60%. Hot 
water supply temperature shall be reset in accordance with Sec. 
434.518.

    517.5 Equipment Sizing and Redundant Equipment. For calculating the 
Energy Cost Budget of Prototype or Reference Buildings, HVAC equipment 
shall be sized to meet the requirements of subsection 403.2.2, without 
using any of the exceptions. The size of equipment shall be that 
required for the building without process loads considered. Redundant or 
emergency equipment need not be simulated if it is controlled so that it 
will not be operated during normal operations of the building. The 
designer shall document the installation of process equipment and the 
size of process loads.
    517.6 For calculating the Design Energy Consumption, actual air flow 
rates and installed equipment size shall be used in the simulation, 
except that excess capacity provided to meet process loads need not be 
modeled unless the process load was not modeled in setting Energy Cost 
Budget. Equipment sizing in the simulation of the Proposed Design shall 
correspond to the equipment actually selected for the design and the 
designer shall not use equipment sized automatically by the simulation 
tool.
    517.6.1 Redundant or emergency equipment need not be simulated if it 
is controlled to not be operated during normal operations of the 
building.



Sec. 434.518  Service water heating.

    518.1 The service water loads for Prototype and Reference Buildings 
are defined in terms of Btu/h per person in Table 518.1.1, Service Hot 
Water Quantities. The service water heating loads from Table 518.1.1 are 
prescribed assumptions for multi-family high-rise residential buildings 
and default assumptions for all other buildings. The same service water 
heating load assumptions shall be made in calculating Design Energy 
Consumption as were used in calculating the Energy Cost Budget.

               Table 518.1.1--Service Hot water Quantities
------------------------------------------------------------------------

\1\ This value is the number to be multiplied by the percentage
  multipliers of the Building Profile Schedules in Table 513.2.b. See
  Table 513.2.a for occupancy levels.
\2\ Total hot water use per dwelling unit for each hour shall be 3,400
  Btu/h times the multi-family high rise residential building SWH system
  multiplier from Table 513.2.b.

    518.2 The service water heating system, including piping losses for 
the Prototype Building, shall be modeled using the methods of the RS-47 
(incorporated by reference, see Sec. 434.701) using a system that meets 
all requirements of subsection 404. The service water heating equipment 
for the Prototype or Reference Building shall be either an electric heat 
pump or natural gas, or if natural gas is not available at the site, 2 
fuel oil. Exception: If electric resistance service water heating is 
preferable to an electric heat pump when analyzed according to the 
criteria of Sec. 434.404.1.4 or when service water temperatures 
exceeding 145 [deg]F are required for a particular application, electric 
resistance water heating may be used.

[[Page 1097]]



Sec. 434.519  Controls.

    519.1 All occupied conditioned spaces in the Prototype, Reference 
and Proposed Design Buildings in all climates shall be simulated as 
being both heated and cooled. The assumptions in this subsection are 
prescribed assumptions. If the Proposed Design does not include 
equipment for cooling or heating, the Design Energy Consumption shall be 
determined by the specifications for calculating the Energy Cost Budget 
as described in Table 517.4.1 HVAC System Description for Prototype and 
Reference Buildings. Exceptions to 519.1 are as follows:
    519.1.1 If a building is to be provided with only heating or 
cooling, both the Prototype or Reference Building and the Proposed 
Design shall be simulated, using the same assumptions. Such an 
assumption cannot be made unless the building interior temperature meets 
the comfort criteria of RS-2 (incorporated by reference, see Sec. 
434.701) at least 98% of the occupied hours during the year.
    519.1.2 If warehouses are not intended to be mechanically cooled, 
both the Energy Cost Budget and Design Energy Consumption shall be 
modeled assuming no mechanical cooling; and
    519.1.3 In climates where winter design temperature (97.5% 
occurrence) is greater than 59 [deg]F, space heating need not be 
modeled.
    519.2 Space temperature controls for the Prototype or Reference 
Building, except multi-family high-rise residential buildings, shall be 
set at 70 [deg]F for space heating and 75 [deg]F for space cooling with 
a deadband per subsection 403.2.6.3. The system shut off during off-
hours shall be according to the schedule in Table 515.2, except that the 
heating system shall cycle on if any space should drop below the night 
setback setting of 55 [deg]F. There shall be no similar setpoint during 
the cooling season. Lesser deadband ranges may be used in calculating 
the Design Energy Consumption. Exceptions to 519.2 are as follows:
    (a) Setback shall not be modeled in determining either the Energy 
Cost Budget or Design Energy Cost if setback is not realistic for the 
Proposed Design, such as 24-hour/day operations. Health facilities need 
not have night setback during the heating season; and
    (b) Hotel/motels and multi-family high-rise residential buildings 
shall have a night setback temperature of 60 [deg]F from 11:00 p.m. to 
6:00 a.m. during the heating season; and
    (c) If deadband controls are not to be installed, the Design Energy 
Cost shall be calculated with both heating and cooling thermostat 
setpoints set to the same value between 70 [deg]F and 75 [deg]F 
inclusive, assumed to be constant for the year.
    519.2.1 For multi-family buildings, the thermostat schedule for the 
dwelling units shall be as in Table 519.1.2, Thermostat Settings for 
Multi-Family High-rise Buildings. The Prototype Building shall use the 
single zone schedule. The Proposed Design shall use the two-zone 
schedule only if zonal thermostatic controls are provided. For Proposed 
Designs that use heat pumps employing supplementary heat, the controls 
used to switch on the auxiliary heat source during morning warm-up 
periods shall be simulated accurately. The thermostat assumptions for 
multi-family high-rise buildings are prescribed assumptions.
    519.3 When providing for outdoor air ventilation in calculating the 
Energy Cost Budget, controls shall be assumed to close the outside air 
intake to reduce the flow of outside air to 0 cfm during setback and 
unoccupied periods. Ventilation using inside air may still be required 
to maintain scheduled setback temperature. Outside air ventilation, 
during occupied periods, shall be as required by RS-41, (incorporated by 
reference, see Sec. 434.701) or the Proposed Design, whichever is 
greater.
    519.4 If humidification is to be used in the Proposed Design, the 
same level of humidification and system type shall be used in the 
Prototype or Reference Building. If dehumidification requires subcooling 
of supply air, then reheat for the Prototype or Reference Building shall 
be from recovered waste heat such as condenser waste heat.

Sec. 434.520  Speculative buildings.

    520.1 Lighting. The interior lighting power allowance (ILPA) for 
calculating the Energy Cost Budget shall be determined from Table 
401.3.2a. The Design Energy Consumption may be based on an assumed 
adjusted lighting power for future lighting improvements.
    520.2 The assumption about future lighting power used to calculate 
the Design Energy Consumption must be documented so that the future 
installed lighting systems may be in compliance with these standards. 
Documentation must be provided to enable future lighting systems to use 
either the Prescriptive method or the Systems Performance method of 
subsection 401.3.
    520.3 Documentation for future lighting systems that use subsection 
401.3 shall be stated as a maximum adjusted lighting power for the 
tenant spaces. The adjusted lighting power allowance for tenant spaces 
shall account for the lighting power provided for the common areas of 
the building.
    520.4 Documentation for future lighting systems that use subsection 
401.3 shall be stated as a required lighting adjustment. The required 
lighting adjustment is the whole building lighting power assumed in 
order to calculate the Design Energy Consumption minus the ILPA value 
from Table 401.3.2c that was used to calculate the Energy Cost Budget. 
When the required lighting adjustment is less than zero, a complete 
lighting design must be developed for one or more representative tenant 
spaces, demonstrating acceptable lighting within the limits of the 
assumed lighting power allowance.
    520.5 HVAC Systems and Equipment. If the HVAC system is not 
completely specified in the plans, the Design Energy Consumption shall 
be based on reasonable assumptions about the construction of future HVAC 
systems and equipment. These assumptions shall be documented so that 
future HVAC systems and equipment may be in compliance with these 
standards.



Sec. 434.521  The simulation tool.

    521.1 Annual energy consumption shall be simulated with a multi-
zone, 8760 hours per year building energy model. The model shall account 
for:
    521.1.1 The dynamic heat transfer of the building envelope such as 
solar and internal gains;
    521.1.2 Equipment efficiencies as a function of load and climate;
    521.1.3 Lighting and HVAC system controls and distribution systems 
by simulating the whole building;
    521.1.4 The operating schedule of the building including night 
setback during various times of the year; and
    521.1.5 Energy consumption information at a level necessary to 
determine the Energy Cost Budget and Design Energy Cost through the 
appropriate utility rate schedules.
    521.1.6 While the simulation tool should simulate an entire year on 
an hour by hour basis (8760 hours), programs that approximate this 
dynamic analysis procedure and provide equivalent results are 
acceptable.
    521.1.7 Simulation tools shall be selected for their ability to 
simulate accurately the relevant features of the building in question, 
as shown in the tool's documentation. For example, a single-zone model 
shall not be used to simulate a large, multi-zone building, and a 
steady-state model such as the degree-day method shall not be used to 
simulate buildings when equipment efficiency or performance is 
significantly affected by the dynamic patterns of

[[Page 1099]]

weather, solar radiation, and occupancy. Relevant energy-related 
features shall be addressed by a model such as daylighting, atriums or 
sunspaces, night ventilation or thermal storage, chilled water storage 
or heat recovery, active or passive solar systems, zoning and controls 
of heating and cooling systems, and ground-coupled buildings. In 
addition, models shall be capable of translating the Design Energy 
Consumption into energy cost using actual utility rate schedules with 
the coincidental electrical demand of a building. Examples of public 
domain models capable of handling such complex building systems and 
energy cost translations available in the United States are DOE--2.1C 
and BLAST 3.0 and in Canada, Energy Systems Analysis Series.
    521.1.8 All simulation tools shall use scientifically justifiable 
documented techniques and procedures for modeling building loads, 
systems, and equipment. The algorithms used in the program shall have 
been verified by comparison with experimental measurements, loads, 
systems, and equipment.



            Subpart F_Building Energy Compliance Alternative



Sec. 434.601  General.

    601.1 This subpart provides an alternative path for compliance with 
the standards that allow for greater flexibility in the design of energy 
efficient buildings using an annual energy use method. This path 
provides an opportunity for the use of innovative designs, materials, 
and equipment such as daylighting, passive solar heating, and heat 
recovery, that may not be adequately evaluated by methods found in 
subpart D.
    601.2 The Building Energy Compliance Alternative shall be used with 
subpart C and subpart D, 401.1, 401.2, 401.3.4 and in conjunction with 
the minimum requirements found in subsections 402.1, 402.2, and 402.3., 
403.1, 403.2.1-7, 403.2.9 and 404.
    601.3 Compliance under this section is demonstrated by showing that 
the calculated annual energy usage for the Proposed Design is less than 
or equal to a calculated Energy Use Budget. (See Figure 601.3, Building 
Energy Compliance Alternative). The analytical procedures in this 
subpart are only for determining design compliance, and are not to be 
used either to predict, document or verify annual energy consumption.

[[Page 1100]]

[GRAPHIC] [TIFF OMITTED] TR06OC00.017

    601.4 Compliance under the Building Energy Use Budget method 
requires a detailed energy analysis, using a conventional simulation 
tool, of the Proposed Design. A life cycle cost analysis shall be used 
to select the fuel source for the HVAC systems, service hot water, and 
process loads from available alternatives. The Annual Energy Consumption 
of the Proposed Design with the life cycle cost-effective fuel selection 
is calculated to determine the modeled energy consumption, called the 
Design Energy Use.
    601.5 The Design Energy Use is defined as the energy that is 
consumed within the five foot line of a proposed building per ft\2\ over 
a 24-hour day, 365-

[[Page 1101]]

day year period and specified operating hours. The calculated Design 
Energy Use is then compared to a calculated Energy Use Budget.
    601.6 Compliance. The Energy Use Budget is determined by calculating 
the annual energy usage for a Reference or Prototype Building that is 
configured to comply with the provisions of subpart E for such 
buildings, except that the fuel source(s) of the Prototype or Reference 
Building shall be the same life cycle cost-effective source(s) selected 
for the Proposed Design. If the Design Energy Use is less than or equal 
to the Energy Use Budget then the proposed design complies with these 
standards.
    601.7 This section provides instructions for determining the Design 
Energy Use and for calculating the Energy Use Budget. The Energy Use 
Budget is the highest allowable calculated annual energy consumption for 
a specified building design. Designers are encouraged to design 
buildings whose Design Energy Use is lower than the Energy Use Budget.



Sec. 434.602  Determination of the annual energy budget.

    602.1 The Energy Use Budget shall be calculated for the appropriate 
Prototype or Reference Building in accordance with the procedures 
prescribed in subsection 502 with the following exceptions: The Energy 
Use Budget shall be stated in units of Btu/ft\2\/yr and the simulation 
tool shall segregate the calculated energy consumption by fuel type 
producing an Energy Use Budget for each fuel (the fuel selections having 
been made by a life cycle cost analysis in determining the proposed 
design).
    602.2 The Energy Use Budget is calculated similarly for the 
Reference or Prototype Building using equation 602.2.
[GRAPHIC] [TIFF OMITTED] TR06OC00.029

    Where EUB1, EUB2, EUBi are the 
calculated annual energy targets for each fuel used in the Reference or 
Prototype building and f1, f2, . . . fi 
are the energy conversion factors given in Table 602.2, Fuel Conversion 
Factors for Computing Design Annual Energy Uses. In lieu of case by case 
calculation of the Energy Use Budget, the designer may construct Energy 
Use Budget tables for the combinations of energy source(s) that may be 
considered in a set of project designs, such as electric heating, 
electric service water, and gas cooling or oil heating, gas service 
water and electric cooling. The values in such optional Energy Use 
Budget tables shall be equal to or less than the corresponding Energy 
Use Budgets calculated on a case by case basis according to this 
section. Energy Use Budget tables shall be constructed to correspond to 
the climatic regions and building types in accordance with provisions 
for Prototype or Reference Building models in subpart E of this part.

------------------------------------------------------------------------
Note: At specific locations where the energy source Btu content varies
  significantly from the value presented above then the local fuel value
  may be used provided there is supporting documentation from the fuel
  source supplier stating this actual energy value and varifying that
  this value will remain consistent for the foreseeable future. The fuel
  content for fuels not given this table shall be determined from the
  best available source.


[[Page 1102]]



Sec. 434.603  Determination of the design energy use.

    603.1 The Design Energy Use shall be calculated by modeling the 
Proposed Design using the same methods, assumptions, climate data, and 
simulation tool as were used to establish the Energy Use Budget, but 
with the design features that will be used in the final building design. 
The simulation tool used shall segregate the calculated energy 
consumption by fuel type giving an annual Design Energy Use for each 
fuel. The sum of the Design Energy Uses multiplied by the fuel 
conversion factors in Table 602.2 yields the Design Energy Use for the 
proposed design:

    Where f1, f2, * * * fi are the fuel 
conversion factors in Table 602.2.
    603.2 Required Life Cycle Cost Analysis for Fuel Selection.
    603.2.1 Fuel sources selected for the Proposed Design and Prototype 
or Reference buildings shall be determined by considering the energy 
cost and other costs and cost savings that occur during the expected 
economic life of the alternative.
    603.2.2 The designer shall use the procedures set forth in subpart A 
of 10 CFR part 436 to make this determination. The fuel selection life 
cycle cost analysis shall include the following steps:
    603.2.2.1 Determine the feasible alternatives for energy sources of 
the Proposed Design's HVAC systems, service hot water, and process 
loads.
    603.2.2.2 Model the Proposed Design including the alternative HVAC 
and service water systems and conduct an annual energy analysis for each 
fuel source alternative using the simulation tool specified in this 
section. The annual energy analysis shall be computed on a monthly basis 
in conformance with subpart E with the exception that all process loads 
shall be included in the calculation. Separate the output of the 
analysis by fuel type.
    603.2.2.3 Determine the unit price of each fuel using information 
from the utility or other reliable local source. During rapid changes in 
fuel prices it is recommended that an average fuel price for the 
previous twelve months be used in lieu of the current price. Calculate 
the annual energy cost of each energy source alternative in accordance 
with procedures in subpart E for the Design Energy Cost. Estimate the 
initial cost of the HVAC and service water systems and other initial 
costs such as energy distribution lines and service connection fees 
associated with each fuel source alternative. Estimate other costs and 
benefits for each alternative including, but not necessarily limited to, 
annual maintenance and repair, periodic and one time major repairs and 
replacements and salvage of the energy and service water systems. Cost 
estimates shall be prepared using professionally recognized cost 
estimating tools, guides and techniques.
    603.2.2.4 Perform a life cycle cost analysis using the procedure 
specified in subsection 603.2.
    603.2.2.5 Compare the total life cycle cost of each energy source 
alternative. The alternative with the lowest total life cycle cost shall 
be chosen as the energy source for the proposed design.



Sec. 434.604  Compliance.

    604.1 Compliance with this section is demonstrated if the Design 
Energy Use is equal to or less than the Energy Use Budget.
[GRAPHIC] [TIFF OMITTED] TR06OC00.031

    604.2 The energy consumption shall be measured at the building five 
foot line for all fuels. Energy consumed from non-depletable energy 
sources and heat recovery systems shall not be included in the Design 
Energy Use calculations. The thermal efficiency of fixtures, equipment, 
systems or plants in the proposed design shall be simulated by the 
selected calculation tool.

[[Page 1103]]



Sec. 434.605  Standard Calculation Procedure.

    605.1 The Standard Calculation Procedure consists of methods and 
assumptions for calculating the Energy Use Budgets for Prototype and 
Reference Buildings and the Energy Use for the Proposed Design. In order 
to maintain consistency between the Energy Use Budgets and the Design 
Energy Use, the input assumptions stated in subsection 510.2 are to be 
used.
    605.2 The terms Energy Cost Budget and Design Energy Cost or Design 
Energy Consumption used in subpart E of this part correlate to Energy 
Use Budget and Design Energy Use, respectively, in subpart F of this 
part.



Sec. 434.606  Simulation tool.

    606.1 The criteria established in subsection 521 for the selection 
of a simulation tool shall be followed when using the compliance path 
prescribed in subpart F of this part.



Sec. 434.607  Life cycle cost analysis criteria.

    607.1 The following life cycle cost criteria applies to the fuel 
selection requirements of this subpart and to option life cycle cost 
analyses performed to evaluate energy conservation design alternatives. 
The fuel source(s) selection shall be made in accordance with the 
requirements of subpart A of 10 CFR part 436. When performing optional 
life cycle cost analyses of energy conservation opportunities the 
designer may use the life cycle cost procedures of subpart A of 10 CFR 
part 436 or OMB Circular 1-94 or an equivalent procedure that meets the 
assumptions listed below:
    607.1.1 The economic life of the Prototype Building and Proposed 
Design shall be 25 years. Anticipated replacements or renovations of 
energy related features and systems in the Prototype or Reference 
Building and Proposed Design during this period shall be included in 
their respective life cycle cost calculations.
    607.1.2 The designer shall follow established professional cost 
estimating practices when determining the costs and benefits associated 
with the energy related features of the Prototype or Reference Building 
and Proposed Design.
    607.1.3 All costs shall be expressed in current dollars. General 
inflation shall be disregarded. Differential escalation of prices 
(prices estimated to rise faster or slower than general inflation) for 
energy used in the life cycle cost calculations shall be those in effect 
at the time of the latest ``Annual Energy Outlook'' (DOE/EIA-0383) as 
published by the Department of Energy's Energy Information 
Administration.
    607.1.4 The economic effects of taxes, depreciation and other 
factors not consistent with the practices of subpart A of 10 CFR part 
436 shall not be included in the life cycle cost calculation.

Sec. 435.2  Definitions.

    For purposes of this part, the following terms, phrases and words 
shall be defined as follows:
    Design for construction means the stage when the energy efficiency 
and sustainability details (such as insulation levels, HVAC systems, 
water-using systems, etc.) are either explicitly determined or 
implicitly included in a project cost specification.
    DOE means U.S. Department of Energy.
    Federal agency means any department, agency, corporation, or other 
entity or instrumentality of the executive branch of the Federal 
Government, including the United States Postal Service, the Federal 
National Mortgage Association, and the Federal Home Loan Mortgage 
Corporation.
    ICC means International Code Council.
    IECC means International Energy Conservation Code.
    IECC Baseline Building 2004 means a building that is otherwise 
identical to the proposed building but is designed to meet, but not 
exceed, the energy efficiency specifications in the ICC International 
Energy Conservation Code, 2004 Supplement Edition, January 2005 
(incorporated by reference, see Sec. 435.3).
    IECC Baseline Building 2009 means a building that is otherwise 
identical to the proposed building but is designed to meet, but not 
exceed, the energy efficiency specifications in the ICC International 
Energy Conservation Code, 2009 Edition, January 2009 (incorporated by 
reference, see Sec. 435.3).
    IECC Baseline Building 2015 means a building that is otherwise 
identical to

[[Page 1107]]

the proposed building but is designed to meet, but not exceed, the 
energy efficiency specifications in the ICC IECC 2015 (incorporated by 
reference, see Sec. 435.3).
    Life-cycle cost means the total cost related to energy conservation 
measures of owning, operating and maintaining a building over its useful 
life as determined in accordance with 10 CFR part 436.
    Life-cycle cost-effective means that the proposed building has a 
lower life-cycle cost than the life-cycle costs of the baseline 
building, as described by 10 CFR 436.19, or has a positive estimated net 
savings, as described by 10 CFR 436.20, or has a savings-to-investment 
ratio estimated to be greater than one, as described by 10 CFR 436.21; 
or has an adjusted internal rate of return, as described by 10 CFR 
436.22, that is estimated to be greater than the discount rate as listed 
in OMB Circular Number A-94 ``Guidelines and Discount Rates for Benefit-
Cost Analysis of Federal Programs.''
    Low-rise residential building means any building three stories or 
less in height above grade that includes sleeping accommodations where 
the occupants are primarily permanent in nature (30 days or more).
    New Federal building means any new building (including a complete 
replacement of an existing building from the foundation up) to be 
constructed by, or for the use of, any federal agency. Such term shall 
include buildings built for the purpose of being leased by a federal 
agency, and privatized military housing.
    Proposed building means the building design of a new Federal low-
rise residential building proposed for construction.

cycle cost analyses of proposed investments in building energy systems, 
building water systems and energy and water conservation measures;
    (c) To promote the use of energy savings performance contracts by 
Federal agencies for implementation of privately financed investment in 
building and facility energy conservation measures for existing 
Federally owned buildings; and
    (d) To promote efficient use of energy in all agency operations 
through general operations plans.

for incorporation into a new building design are insignificant, a 
Federal agency may presume that such a system is life cycle cost-
effective without further analysis.
    (b) A Federal agency may presume that an investment in an energy or 
water conservation measure retrofit to an existing Federal building is 
not life cycle cost-effective for Federal investment if the Federal 
building is--
    (1) Occupied under a short-term lease with a remaining term of one 
year or less, and without a renewal option or with a renewal option 
which is not likely to be exercised;
    (2) Occupied under a lease which includes the cost of utilities in 
the rent and does not provide a pass-through of energy or water savings 
to the government; or

Sec. 436.14  Methodological assumptions.

    (a) Each Federal Agency shall discount to present values the future 
cash flows established in either current or constant dollars consistent 
with the nominal or real discount rate, and related tables, published in 
the annual supplement to the Life Cycle Costing Manual for the Federal 
Energy Management Program (NIST 85-3273) and determined annually by DOE 
as follows--
    (1) The nominal discount rate shall be a 12 month average of the 
composite yields of all outstanding U.S. Treasury bonds neither due nor 
callable in less than ten years, as most recently reported by the 
Federal Reserve Board; and
    (2) Subject to a ceiling of 10 percent and a floor of three percent 
the real discount rate shall be a 12 month average of the composite 
yields of all outstanding U.S. Treasury bonds neither due nor callable 
in less than ten years, as most recently reported by the Federal Reserve 
Board, adjusted to exclude estimated increases in the general level of 
prices consistent with projections of inflation in the most recent 
Economic Report of the President's Council of Economic Advisors.
    (b) Each Federal agency shall assume that energy prices will change 
at rates projected by DOE's Energy Information Administration and 
published by NIST annually no later than the beginning of the fiscal 
year in the Annual Supplement to the Life Cycle Costing Manual for the 
Federal Energy Management Program, in tables consistent with the 
discount rate determined by DOE under paragraph (a) of this section, 
except that--
    (1) If the Federal agency is using component prices under Sec. 
436.14(c), that agency may use corresponding component escalation rates 
provided by the energy or water supplier.
    (2) For Federal buildings in foreign countries, the Federal agency 
may use a ``reasonable'' escalation rate.
    (c) Each Federal agency shall assume that the price of energy or 
water in the base year is the actual price charged for energy or water 
delivered to the Federal building and may use actual component prices as 
provided by the energy or water supplier.
    (d) Each Federal agency shall assume that the appropriate study 
period is as follows:
    (1) For evaluating and ranking alternative retrofits for an existing 
Federal building, the study period is the expected life of the retrofit, 
or 40 years from the beginning of beneficial use, whichever is shorter.
    (2) For determining the life cycle costs or net savings of mutually 
exclusive alternatives for a given building energy system or building 
water system (e.g., alternative designs for a particular system or size 
of a new or retrofit building energy system or building water system), a 
uniform study period for all alternatives shall be assumed which is 
equal to--
    (i) The estimated life of the mutually exclusive alternative having 
the longest life, not to exceed 40 years from the

[[Page 1117]]

beginning of beneficial use with appropriate replacement and salvage 
values for each of the other alternatives; or
    (ii) The lowest common multiple of the expected lives of the 
alternative, not to exceed 40 from the beginning of beneficial use with 
appropriate replacement and salvage values for each alternative.
    (3) For evaluating alternative designs for a new Federal building, 
the study period extends from the base year through the expected life of 
the building or 40 years from the beginning of beneficial use, whichever 
is shorter.
    (e) Each Federal agency shall assume that the expected life of any 
building energy system or building water system is the period of service 
without major renewal or overhaul, as estimated by a qualified engineer 
or architect, as appropriate, or any other reliable source except that 
the period of service of a building energy or water system shall not be 
deemed to exceed the expected life of the owned building, or the 
effective remaining term of the leased building (taking into account 
renewal options likely to be exercised).
    (f) Each Federal agency may assume that investment costs are a lump 
sum occurring at the beginning of the base year, or may discount future 
investment costs to present value using the appropriate present worth 
factors under paragraph (a) of this section.
    (g) Each Federal agency may assume that energy or water costs and 
non-fuel or non-water operation and maintenance costs begin to accrue at 
the beginning of the base year or when actually projected to occur.
    (h) Each Federal agency may assume that costs occur in a lump sum at 
any time within the year in which they are incurred.
    (i) This section shall not apply to calculations of estimated simple 
payback time under Sec. 436.22 of this part.

Sec. 436.15  Formatting cost data.

    In establishing cost data under Sec. Sec. 436.16 and 436.17 and 
measuring cost effectiveness by the modes of analysis described by Sec. 
436.19 through Sec. 436.22, a format for accomplishing the analysis 
which includes all required input data and assumptions shall be used. 
Subject to Sec. 436.18(b), Federal agencies are encouraged to use 
worksheets or computer software referenced in the Life Cycle Cost Manual 
for the Federal Energy Management Program.



Sec. 436.16  Establishing non-fuel and non-water cost categories.

    (a) The relevant non-fuel cost categories are--
    (1) Investment costs;
    (2) Non-fuel operation and maintenance cost;
    (3) Replacement cost; and
    (4) Salvage value.
    (b) The relevant non-water cost categories are--
    (1) Investment costs;
    (2) Non-water operation and maintenance cost;
    (3) Replacement cost; and
    (4) Salvage value.
    (c) The present value of recurring costs is the product of the base 
year value of recurring costs as multiplied by the appropriate uniform 
present worth factor under Sec. 436.14, or as calculated by computer 
software indicated in Sec. 436.18(b) and used with the official 
discount rate and escalation rate assumptions under Sec. 436.14. When 
recurring costs begin to accrue at a later time, subtract the present 
value of recurring costs over the delay, calculated using the 
appropriate uniform present worth factor for the period of the delay, 
from the present value of recurring costs over the study period or, if 
using computer software, indicate a delayed beneficial occupancy date.
    (d) The present value of non-recurring cost under Sec. 436.16(a) is 
the product of the non-recurring costs as multiplied by appropriate 
single present worth factors under Sec. 436.14 for the respective years 
in which the costs are expected to be incurred, or as calculated by 
computer software provided or approved by DOE and used with the official 
discount rate and escalation rate assumptions under Sec. 436.14.

[55 FR 48220, Nov. 20, 1990, as amended at 61 FR 32650, June 25, 1996]

[[Page 1118]]



Sec. 436.17  Establishing energy or water cost data.

    (a) Each Federal agency shall establish energy costs in the base 
year by multiplying the total units of energy used in the base year by 
the price per unit of energy in the base year as determined in 
accordance with Sec. 436.14(c).
    (b) When energy costs begin to accrue in the base year, the present 
value of energy costs over the study period is the product of energy 
costs in the base year as established under Sec. 436.17(a), multiplied 
by the appropriate modified uniform present worth factor adjusted for 
energy price escalation for the applicable region, sector, fuel type, 
and study period consistent with Sec. 436.14, or as calculated by 
computer software provided or approved by DOE and used with the official 
discount rate and escalation rate assumptions under Sec. 436.14. When 
energy costs begin to accrue at a later time, subtract the present value 
of energy costs over the delay, calculated using the adjusted, modified 
uniform present worth factor for the period of delay, from the present 
value of energy costs over the study period or, if using computer 
software, indicate a delayed beneficial occupancy date.
    (c) Each Federal agency shall establish water costs in the base year 
by multiplying the total units of water used in the base year by the 
price per unit of water in the base year as determined in accordance 
with Sec. 436.14(c).
    (d) When water costs begin to accrue in the base year, the present 
value of water costs over the study period is the product of water costs 
in the base year as established under Sec. 436.17(a), or as calculated 
by computer software provided or approved by DOE and used with the 
official discount rate and assumptions under Sec. 436.14. When water 
costs begin to accrue at a later time, subtract the present value of 
water costs over the delay, calculated using the uniform present worth 
factor for the period of delay, from the present value of water costs 
over the study period or, if using computer software, indicate a delayed 
beneficial occupancy date.

Sec. 436.18  Measuring cost-effectiveness.

    (a) In accordance with this section, each Federal agency shall 
measure cost-effectiveness by combining cost data established under 
Sec. Sec. 436.16 and 436.17 in the appropriate mode of analysis as 
described in Sec. 436.19 through Sec. 436.22.
    (b) Federal agencies performing LCC analysis on computers shall use 
either the Federal Buildings Life Cycle Costing (FBLCC) software 
provided by DOE or software consistent with this subpart.
    (c) Replacement of a building energy or water system with an energy 
or water conservation measure by retrofit to an existing Federal 
building or by substitution in the design for a new Federal building 
shall be deemed cost-effective if--
    (1) Life cycle costs, as described by Sec. 436.19, are estimated to 
be lower; or
    (2) Net savings, as described by Sec. 436.20, are estimated to be 
positive; or
    (3) The savings-to-investment ratio, as described by Sec. 436.21, 
is estimated to be greater than one; or
    (4) The adjusted internal rate of return, as described by Sec. 
436.22, is estimated to be greater than the discount rate as set by DOE.
    (d) As a rough measure, each Federal agency may determine estimated 
simple payback time under Sec. 436.23, which indicates whether a 
retrofit is likely to be cost effective under one of the four 
calculation methods referenced in Sec. 436.18(c). An energy or water 
conservation measure alternative is likely to be cost-effective if 
estimated payback time is significantly less than the useful life of 
that system, and of the Federal building in which it is to be installed.
    (e) Mutually exclusive alternatives for a given building energy or 
water system, considered in determining such matters as the optimal size 
of a solar energy system, the optimal thickness of insulation, or the 
best choice of double-glazing or triple-glazing for windows, shall be 
compared and evaluated on the basis of life cycle costs or net savings 
over equivalent study periods. The alternative which is estimated to 
result in the lowest life cycle costs or the highest net savings shall 
be deemed the most cost-effective because it tends

[[Page 1119]]

to minimize the life cycle cost of Federal building.
    (f) When available appropriations will not permit all cost-effective 
energy or water conservation measures to be undertaken, they shall be 
ranked in descending order of their savings-to-investment ratios, or 
their adjusted internal rate of return, to establish priority. If 
available appropriations cannot be fully exhausted for a fiscal year by 
taking all budgeted energy or water conservation measures according to 
their rank, the set of energy or water conservation measures that will 
maximize net savings for available appropriations should be selected.
    (g) Alternative building designs for new Federal buildings shall be 
evaluated on the basis of life cycle costs. The alternative design which 
results in the lowest life cycle costs for a given new building shall be 
deemed the most cost-effective.

[55 FR 48220, Nov. 20, 1990, as amended at 61 FR 32650, June 25, 1996]



Sec. 436.19  Life cycle costs.

    Life cycle costs are the sum of the present values of--
    (a) Investment costs, less salvage values at the end of the study 
period;
    (b) Non-fuel operation and maintenance costs:
    (c) Replacement costs less salvage costs of replaced building 
systems; and
    (d) Energy and/or water costs.

[55 FR 48220, Nov. 20, 1990, as amended at 61 FR 32651, June 25, 1996]



Sec. 436.20  Net savings.

    For a retrofit project, net savings may be found by subtracting life 
cycle costs based on the proposed project from life cycle costs based on 
not having it. For a new building design, net savings is the difference 
between the life cycle costs of an alternative design and the life cycle 
costs of the basic design.



Sec. 436.21  Savings-to-investment ratio.

    The savings-to-investment ratio is the ratio of the present value 
savings to the present value costs of an energy or water conservation 
measure. The numerator of the ratio is the present value of net savings 
in energy or water and non-fuel or non-water operation and maintenance 
costs attributable to the proposed energy or water conservation measure. 
The denominator of the ratio is the present value of the net increase in 
investment and replacement costs less salvage value attributable to the 
proposed energy or water conservation measure.

[61 FR 32651, June 25, 1996]



Sec. 436.22  Adjusted internal rate of return.

    The adjusted internal rate of return is the overall rate of return 
on an energy or water conservation measure. It is calculated by 
subtracting 1 from the nth root of the ratio of the terminal value of 
savings to the present value of costs, where n is the number of years in 
the study period. The numerator of the ratio is calculated by using the 
discount rate to compound forward to the end of the study period the 
yearly net savings in energy or water and non-fuel or non-water 
operation and maintenance costs attributable to the proposed energy or 
water conservation measure. The denominator of the ratio is the present 
value of the net increase in investment and replacement costs less 
salvage value attributable to the proposed energy or water conservation 
measure.

[61 FR 32651, June 25, 1996]



Sec. 436.23  Estimated simple payback time.

    The estimated simple payback time is the number of years required 
for the cumulative value of energy or water cost savings less future 
non-fuel or non-water costs to equal the investment costs of the 
building energy or water system, without consideration of discount 
rates.

[61 FR 32651, June 25, 1996]



Sec. 436.24  Uncertainty analyses.

    If particular items of cost data or timing of cash flows are 
uncertain and are not fixed under Sec. 436.14, Federal agencies may 
examine the impact of uncertainty on the calculation of life cycle cost 
effectiveness or the assignment of rank order by conducting additional 
analyses using any standard engineering economics method such as

[[Page 1120]]

sensitivity and probabilistic analysis. If additional analysis casts 
substantial doubt on the life cycle cost analysis results, a Federal 
agency should consider obtaining more reliable data or eliminating the 
building energy or water system alternative.

2003. This subpart applies in addition to the Federal Acquisition 
Regulation at Title 48 of the CFR and related Federal agency 
regulations. The provisions of this subpart are controlling with regard 
to energy savings performance contracts notwithstanding any conflicting 
provisions of the Federal Acquisition Regulation and related Federal 
agency regulations.
    (b) Utility incentive programs. Nothing in this subpart shall 
preclude a Federal agency from--
    (1) Participating in programs to increase energy efficiency, 
conserve water, or manage electricity demand conducted by gas, water, or 
electric utilities and generally available to customers of such 
utilities;
    (2) Accepting financial incentives, goods, or services generally 
available from any such utility to increase energy efficiency or to 
conserve water or manage electricity demand; or
    (3) Entering into negotiations with electric, water, and gas 
utilities to design cost-effective demand management and conservation 
incentive programs to address the unique needs of each Federal agency.
    (c) Promoting competition. To the extent allowed by law, Federal 
agencies should encourage utilities to select contractors for the 
conduct of utility incentive programs in a competitive manner to the 
maximum extent practicable.

Federal agencies to make an initial selection based, in part, on 
proposals containing estimated energy cost savings and energy unit 
savings, with contract award conditioned on confirmation through a 
detailed energy survey that the guaranteed energy cost savings are 
within a certain percentage (specified in the solicitation) of the 
estimated amount; and
    (iv) May state that if the Federal agency requires a detailed energy 
survey which identifies life cycle cost effective energy conservation 
measures not in the initial proposal, the contract may include such 
measures.
    (3) Based on its evaluation of the technical and price proposals 
submitted, any applicable financing agreement (including lease-
acquisitions, if any), statements of qualifications submitted under 
Sec. 436.32 of this subpart, and any other information determines to be 
relevant, the Federal agency may select a firm on a qualified list to 
conduct the project.
    (4) If a proposed energy cost savings project involves a large 
facility with too many contiguously related buildings and other 
structures at one site for proposing firms to assume the costs of a 
preliminary energy survey of all such structures, the Federal agency--
    (i) May request technical and price proposals for a representative 
sample of buildings and other structures and may select a firm to 
conduct the proposed project; and
    (ii) After selection of a firm, but prior to award of an energy 
savings performance contract, may request the selected firm to submit 
technical and price proposals for all or some of the remaining buildings 
and other structures at the site and may include in the award for all or 
some of the remaining buildings and other structures.
    (5) After selection under paragraph (a)(3) or (a)(4) of this 
section, but prior to award, a Federal agency may require the selectee 
to conduct a detailed energy survey to confirm that guaranteed energy 
cost savings are within a certain percentage (specified in the 
solicitation) of estimated energy cost savings in the selectee's 
proposal. If the detailed energy survey does not confirm that guaranteed 
energy savings are within the fixed percentage of estimated savings, the 
Federal agency may select another firm from those within the competitive 
range.
    (b) Unsolicited proposals. Federal agencies may--
    (1) Consider unsolicited energy savings performance contract 
proposals from firms on a qualified contractor list under this subpart 
which include

[[Page 1123]]

technical and price proposals and the text of any financing agreement 
(including a lease-acquisition) without regard to the requirements of 48 
CFR 15.602 and 15.602-2(a)(1); 48 CFR 15.603; and 48 CFR 15.607(a), 
(a)(2), (a)(3), (a)(4) and (a)(5).
    (2) Reject an unsolicited proposal that is too narrow because it 
does not address the potential for significant energy conservation 
measures from other than those measures in the proposal.
    (3) After requiring a detailed energy survey, if appropriate, and 
determining that technical and price proposals are adequate, award a 
contract to a firm on a qualified contractor list under this subpart on 
the basis of an unsolicited proposal, provided that the Federal agency 
complies with the following procedures--
    (i) An award may not be made to the firm submitting the unsolicited 
proposal unless the Federal agency first publishes a notice in the 
Commerce Business Daily acknowledging receipt of the proposal and 
inviting other firms on the qualified list to submit competing 
proposals.
    (ii) Except for unsolicited proposals submitted in response to a 
published general statement of agency needs, no award based on such an 
unsolicited proposal may be made in instances in which the Federal 
agency is planning the acquisition of an energy conservation measure 
through an energy savings performance contract.
    (c) Certified cost or pricing data. (1) Energy savings performance 
contracts under this part are firm fixed-price contracts.
    (2) Pursuant to the authority provided under section 304A(b)(1)(B) 
of the Federal Property and Administrative Services Act of 1049, the 
heads of procuring activities shall waive the requirement for submission 
of certified cost or pricing data. However, this does not exempt 
offerors from submitting information (including pricing information) 
required by the Federal agency to ensure the impartial and comprehensive 
evaluation of proposals.

Sec. 436.103  Program goal setting.

    (a) In developing and revising plans for a projected 10-year plan 
each agency shall establish and maintain energy conservation goals in 
accordance with the requirements of this section.
    (b) Agencies shall establish three types of conservation goals:
    (1) Energy consumption goals, by fuel type by functional category 
(see appendix B).
    (2) Energy efficiency goals by fuel type by functional category (see 
appendix B).
    (3) Fuel switching goals for shifting energy use from oil and

sources (see appendix B).
    (c) General operations energy conservation goals shall be 
established by each Federal agency with the broad purpose of achieving 
reductions in total energy consumption and increased efficiency without 
serious mission degradation or unmitigated negative environmental 
impacts. Within the broad framework, each agency should seek first to 
reduce energy consumption per unit of output in each applicable 
functional category. In evaluating energy efficiency, each agency should 
select and use standards of measurement which are consistent throughout 
the planning period. Particular attention should be given to increased 
energy use efficiency in nonrenewable fuel consumption. The second focus 
of attention should be on initiatives which shift energy use from oil 
and natural gas to other fuels in more plentiful supply from domestic 
sources.



Sec. 436.104  Energy conservation measures and standards.

    (a) Each agency shall consider for inclusion in its plan the 
measures identified in appendix C of this subpart.
    (b) The following questions should be considered in the evaluation 
of each measure:
    (1) Does this measure provide an incentive or disincentive?
    (2) What is the estimate of savings by fuel type?
    (3) What are the direct and indirect impacts of this measure?
    (4) Is this measure to be mandatory throughout the agency?
    (5) If not mandatory, under what circumstances will it be 
implemented, and who will be responsible for determining specific 
applicability?
    (6) Who will be the direct participants in the implementation of 
this measure?
    (7) What incentives (if any) are to be provided for the 
participants?
    (8) When will this measure be implemented?
    (9) Will this measure be implemented in a single step or will it be 
phased in? If it will be phased in, over what period of time?
    (10) Will performance of the measure be evaluated and reported?
    (11) By what criterion will performance be determined?

[[Page 1130]]

    (12) Who will prepare performance reports?
    (13) What is the reporting chain?
    (14) What is the reporting period?
    (c) Each agency will take all necessary steps to implement the 
energy conservation standards for general operations listed in appendix 
A (reserved).



Sec. 436.105  Emergency conservation plan.

    (a) Each agency shall establish an emergency conservation plan, a 
summary of which shall be included in the general operations plan, for 
assuaging the impact of a sudden disruption in the supply of oil-based 
fuels, natural gas or electricity. Priorities for temporarily reducing 
missions, production, services, and other programmatic or functional 
activities shall be developed in accordance with paragraph (b) of this 
section. Planning for emergencies is to address both buildings and 
general operations. Provisions shall be made for testing emergency 
actions to ascertain that they are effective.
    (b) Federal agencies shall prepare emergency conservation plans for 
10 percent, fifteen percent, and 20 percent reduction compared to the 
previous fiscal year in gasoline, other oil-based fuels, natural gas, or 
electricity for periods of up to 12 months. In developing these plans, 
agencies shall consider the potential for emergency reductions in energy 
use in buildings and facilities which the agency owns, leases, or has 
under contract and by employees through increased use of car and van 
pooling, preferential parking for multipassenger vehicles, and greater

 Sec. Appendix A to Part 436--Energy Conservation Standards for General 
                          Operations [Reserved]



          Sec. Appendix B to Part 436--Goal Setting Methodology

    In establishing and updating agency goals for energy conservation, 
the following methodology or an equivalent method should be utilized:
    (a) For overall energy consumption--
    (1) An analysis shall be made to determine what factors have the 
most significant impact upon the amount of each fuel type used by the 
agency in performing functions in support of its overall mission. 
Consideration is to be given, but not limited to, the following factors: 
Number of people using energy; number of vehicles using gasoline; 
amounts of other equipment using energy; tempo of operations (one, two, 
or three shifts); the type of operations (degree of equipment or labor 
intensity); equipment fuel limitations; environmental conditions 
(tropical versus arctic, etc.); budget levels for fuel, operations, 
maintenance, and equipment acquisition; and phase-out schedule (of older 
equipment or plants which may be inefficient). After identifying these 
factors, a further analysis shall be made to identify any projected 
workload changes in the quality or quantity of these factors on a yearly 
basis up to 1990.
    (2) Based upon the analysis in (a)(1) and an evaluation of available 
information on past energy usage, a baseline of energy use by fuel type 
by functional category shall be established beginning with FY 1975. In 
addition to ``General Transportation,'' other functional categories 
should be selected to enhance energy management. Total fuel use for a 
particular activity may be allocated to the functional category for 
which the preponderance of fuel is used. Figure B-1 is an example of one 
such baseline.

[[Page 1133]]

[GRAPHIC] [TIFF OMITTED] TC04OC91.241

    This example shows an increase in energy use, for a specific fuel 
type, during the period 1975-1981, with a further increase from 1981 to 
1984 and a leveling off and no growth from 1984-1990. A justification, 
based on factors as discussed above, shall accompany each baseline.
    (3) Thereafter, analyses should be made of the measures available 
for reducing the energy consumption profiles without adverse impact on 
mission accomplishment. Finding viable opportunities for reducing energy 
use, increasing energy efficiency and switching energy sources, will 
require consultation with specialists in the fields of operations, 
maintenance, engineering, design, and economics, and consideration of 
the measures identified in appendix C. The DOE Federal Energy Management 
Programs Office can, upon request, provide information on where such 
resources can be located. Once these measures are identified, they are 
to be incorporated into a time-phased investment program, (using where 
appropriate, the life cycle costing factors and methodology in subpart A 
of this part). If investment and other costs for implementing a measure 
are insignificant, a Federal agency may presume that a measure is cost-
effective without further analysis. An estimate must then be made as to 
the lead time required to implement the program and realize energy 
reductions.
    Figure B-2 shows a summarized investment program, which should be 
accompanied by a detailed description of the measures, projects, and 
programs making up the total planned investments for each year. This 
summary need not be by function or fuel type.

[[Page 1134]]

[GRAPHIC] [TIFF OMITTED] TC04OC91.242

    These analyses should enable the agency to project an energy 
consumption goal, with the assumption that funds for executing the 
planned projects will be approved. Figure B-3 shows a new energy use 
profile, with planned initiatives and related investments taken into 
consideration, and the resulting goal entitled ``Energy Use With A 
Plan'' superimposed on Figure B-1. Included are the anticipated effects 
on consumption cause by improvements in energy efficiency and fuel 
switching.
[GRAPHIC] [TIFF OMITTED] TC04OC91.243

    A comparison of these projections will show the energy use avoidance 
resulting from the investment program as depicted in Figure B-2. Using 
the prices of fuel contained in appendix C to subpart A, the dollars 
saved can be projected against the dollars invested. Life cycle costing 
methodology pursuant to subpart A, will be used to determine priorities 
for submitting individual initiatives into the appropriate budget year.
    (b) For energy efficiencies--Energy efficiency baselines and goals 
for each fuel type shall be calculated using the same consumption 
factors and similar methodology to that outlined in paragraph (a). 
Energy consumption by fuel type shall be linked to mission through the 
functional categories listed in Sec. 436.106(a)(2). This will identify 
a rate which will indicate energy efficiency trends. This linkage may be 
accomplished through the following algorithm:

[[Page 1135]]

    Step 1: Determine functional categories from section 436.106(a)(2) 
which best describe the Agency overall mission.
    Step 2: Determine types of fuels used to support the functions 
selected in Step 1.
    Step 3: Determine quantities of fuel consumed or planned for 
consumption over a specific period of time.
    Step 4: Determine quantity of output of function for same period of 
time used in Step 3. Quantify output in a standard measure which best 
describes functional category.
    Step 5: Determine the energy efficiency ratio by dividing quantity 
from Step 4 by quantity from Step 3.
    This ratio of fuel consumed to a unit measure of output will be used 
to develop a projection of a baseline and goals through 1990, and used 
in reporting variance. Examples of ratios that should be considered are:

     Production or industrial process type operations

Ton of product

Cu. ft. of natural gas

     Services, such as postal delivery

Customers served or
pounds delivered

Gallons of automotive
gasoline

     General transportation

Passenger miles

Gallons of automotive gasoline

     Training

Persons trained
or in training

Gallons of navy special

    Agencies shall select one or more of these ratios, which shall be 
used throughout the planning period, or use more appropriate energy 
efficiency ratios, to describe their overall functions. Figure B-4 
illustrates the planning baseline and goal resulting from this type of 
analysis.

[[Page 1136]]

[GRAPHIC] [TIFF OMITTED] TC04OC91.244

    (c) For fuel switching--Fuel switching goals for gasoline other oil-
based fuel and natural gas may be calculated as follows:
    Step 1: For each fiscal year, identify investments, where 
appropriate, in fuel switching

[[Page 1137]]

from gasoline, other oil-based fuel and natural gas to alternate 
renewable or nonrenewable fuel sources.
    Step 2: Project for each fiscal year, the avoidance in the use of 
gasoline, other oil-based fuel and natural gas resulting from previous 
fuel switching investments.
    Completion of these steps will permit the formulation of charts such 
as that shown in Figure B-5.

    Sec. Appendix D to Part 436--Energy Program Conservation Elements

    (a) In all successful energy conservation programs, certain key 
elements need to be present. The elements listed below must be 
incorporated into each agency conservation program and must be reflected 
in the 10-year plan prescribed in Sec. 436.102. Those organizations 
that have already developed programs should review them to determine 
whether the present management systems incorporate these elements.
    (1) Top Management Control. Top management must have a personal and 
sustained commitment to the program, provide active direction and 
motivation, and require regular review of overall energy usage at senior 
staff meetings.
    (2) Line Management Accountability. Line managers must be 
accountable for the energy conservation performance of their 
organizations and should participate in establishing realistic goals and 
developing strategies and budgets to meet these goals.
    (3) Formal Planning. An overall 10-year plan for the period 1980-
1990 must be developed and formalized which sets forth performance-
oriented conservation goals, including the categorized reduction in 
rates of energy consumption that the program is expected to realize. The 
plan will be supplemented by guidelines enumerating specific 
conservation procedures that will be followed. These procedures and 
initiatives must be life cycle cost-effective as well as energy 
efficient.
    (4) Goals. Goals must be established in a measurable manner to 
answer questions of ``Where are we?'' ``Where do we want to go?'' ``Are 
we getting there?'' and ``Are our initiatives for getting there life 
cycle cost-effective?''
    (5) Monitoring. Progress must be reviewed periodically both at the 
agency headquarters and at local facility levels to identify program 
weakness or additional areas for conservation actions. Progress toward 
achievement of goals should be assessed, and explanations should be 
required for non-achievement or unusual variations in energy use. 
Monitoring should include personal inspections and staff visits, 
management information reporting and audits.
    (6) Using Technical Expertise. Personnel with adequate technical 
background and knowledge of programmatic objectives should be used to 
help management set technical goals and parameters for efficient 
planning and implementation of energy conservation programs. These 
technicians should work in conjunction with the line managers who are 
accountable for both mission accomplishment and energy conservation.
    (7) Employee Awareness. Employees must gain an awareness of energy 
conservation through formal training and employee information programs. 
They should be invited to participate in the process of developing an 
energy conservation program, and to submit definitive suggestions for 
conservation of energy.
    (8) Energy Emergency Planning. Every energy management plan must 
provide for programs to respond to contingencies that may occur at the 
local, state or National level. Programs must be developed for potential 
energy emergency situations calling for reductions of 10 percent, 15 
percent and 20 percent for up to 12 months. Emergency plans must be 
tested to ascertain their effectiveness.
    (9) Budgetary and Fiscal Support. Resources necessary for the energy 
conservation program must be planned and provided for, and the fiscal 
systems adjusted to support energy management investments and 
information reporting.
    (10) Environmental Considerations. Each agency shall fulfill its 
obligations under the National Environmental Policy Act in developing 
its plan.

that participate in the program established under this Part are required 
to treat all requests for information concerning applicants and 
recipients of WAP funds in a manner consistent with the Federal 
Government's treatment of information requested under the Freedom of 
Information Act (FOIA), 5 U.S.C. 552, including the privacy protections 
contained in Exemption (b)(6) of the FOIA, 5 U.S.C. 552(b)(6). Under 5 
U.S.C. 552(b)(6), information relating to an individual's eligibility 
application or the individual's participation in the program, such as 
name, address, or income information, are generally exempt from 
disclosure.
    (2) A balancing test must be used in applying Exemption (b)(6) in 
order to determine:
    (i) Whether a significant privacy interest would be invaded;
    (ii) Whether the release of the information would further the public 
interest by shedding light on the operations or activities of the 
Government; and
    (iii) Whether in balancing the privacy interests against the public 
interest, disclosure would constitute a clearly unwarranted invasion of 
privacy.
    (3) A request for personal information including but not limited to 
the names, addresses, or income information of WAP applicants or 
recipients

[[Page 1141]]

would require the State or other service provider to balance a clearly 
defined public interest in obtaining this information against the 
individuals' legitimate expectation of privacy.
    (4) Given a legitimate, articulated public interest in the 
disclosure, States and other service providers may release information 
regarding recipients in the aggregate that does not identify specific 
individuals. However, a State or service provider must apply an FOIA 
Exemption (b)(6) balancing test to any request for information that can 
not be satisfied by such less-intrusive methods.

    (2) Subtract 171,258,000 from total program allocations.
    (3) Calculate each State's formula share as follows:
    (i) Divide the number of ``Low Income'' households in each State by 
the number of ``Low Income'' households in the United States and 
multiply by 100.
    (ii) Divide the number of ``Heating Degree Days'' for each State by 
the median ``Heating Degree Days'' for all States.
    (iii) Divide the number of ``Cooling Degree Days'' for each State by 
the median ``Cooling Degree Days'' for all States, then multiply by 0.1.
    (iv) Calculate the sum of the two numbers from paragraph (b)(3)(ii) 
and (iii) of this section.
    (v) Divide the residential energy expenditures for each State by the 
number of households in the State.
    (vi) Divide the sum of the residential energy expenditures for the 
States in each Census division by the sum of the households for the 
States in that division.
    (vii) Divide the quotient from paragraph (b)(3)(v) of this section 
by the quotient from paragraph (b)(3)(vi) of this section.
    (viii) Multiply the quotient from paragraph (b)(3)(vii) of this 
section for each State by the residential energy expenditures per low-
income household for its respective Census division.
    (ix) Divide the product from paragraph (b)(3)(viii) of this section 
for each State by the median of the products of all States.
    (x) Multiply the results for paragraph (b)(3)(i), (iv) and (ix) of 
this section for each State.
    (xi) Divide the product in paragraph (b)(3)(x) of this section for 
each State by the sum of the products in paragraph (b)(3)(x) of this 
section for all States.
    (4) Calculate each State's program allocation as follows:
    (i) Multiply the remaining funds calculated in paragraph (b)(2) of 
this section by the formula share calculated in paragraph (b)(3)(xi) of 
this section,
    (ii) Add the base allocation from paragraph (b)(1) of this section 
to the product of paragraph (b)(4)(i) of this section.
    (c) Should total program allocations for any fiscal year fall below 
$209,724,761, then each State's program allocation shall be reduced from 
its allocated amount under a total program allocation of $209,724,761 by 
the same percentage as total program allocations for the fiscal year 
fall below $209,724,761.
    (d) All data sources used in the development of the formula are 
publicly available. The relevant data is available from the Bureau of 
the Census, the

[[Page 1145]]

Department of Energy's Energy Information Administration and the 
National Oceanic and Atmospheric Administration.
    (e) Should updates to the data used in the formula become available 
in any fiscal year, these changes would be implemented in the formula in 
the following program year.
    (f) DOE may reduce the program allocation for a State by the amount 
DOE determines cannot be reasonably expended by a grantee to weatherize 
dwelling units during the budget period for which financial assistance 
is to be awarded. In reaching this determination, DOE will consider the 
amount of unexpended financial assistance currently available to a 
grantee under this part and the number of dwelling units which remains 
to be weatherized with the unexpended financial assistance.
    (g) DOE may increase the program allocation of a State by the amount 
DOE determines the grantee can expend to weatherize additional dwelling 
units during the budget period for which financial assistance is to be 
awarded.
    (h) The Support Office Director shall notify each State of the 
program allocation for which that State is eligible to apply.

benefits under this part equivalent to the assistance provided to other 
low-income persons in the State under this part and
    (2) The low-income members of such tribe would be better served by 
means of a grant made directly to provide such assistance.
    (b) In any State for which the Support Office Director shall have 
made the determination referred to in paragraph (a) of this section, the 
Support Office Director shall reserve from the sums that would otherwise 
be allocated to the State under this part not less than 100 percent, or 
more than 150 percent, of an amount which bears the same ratio to the 
State's allocation for the fiscal year involved as the population of all 
low-income Native Americans for whom a determination under paragraph (a) 
of this section has been made bears to the population of all low-income 
persons in the State.
    (c) The Support Office Director shall make the determination 
prescribed in paragraph (a) of this section in the event a State:
    (1) Does not apply within the sixty-day time period prescribed in

paragraph (b) of this section shall be granted to the tribal 
organization serving the individuals for whom the determination has been 
made, or where there is no tribal organization, to such other entity as 
the Support Office Director determines is able to provide adequate 
weatherization assistance pursuant to this part. Where the Support 
Office Director intends to make a grant to an organization to perform 
services benefiting more than one Indian tribe, the approval of each 
Indian tribe shall be a prerequisite for the issuance of a notice of 
grant award.
    (e) Within 30 days after the Support Office Director has reserved 
funds pursuant to paragraph (b) of this section, the Support Office 
Director shall give written notice to the tribal organization or other 
qualified entity of the amount of funds reserved and its eligibility to 
apply therefor.

Sec. 440.21  Weatherization materials standards and energy audit
procedures.

    (a) Paragraph (b) of this section describes the required standards 
for weatherization materials. Paragraph (c)(1) of this section describes 
the performance and quality standards for renewable energy systems. 
Paragraph (c)(2) of this section specifies the procedures and criteria 
that are used for considering a petition from a manufacturer requesting 
the Secretary to certify an item as a renewable energy system. 
Paragraphs (d) and (e) of this section describe the cost-effectiveness 
tests that weatherization materials must pass before they may be 
installed in an eligible dwelling unit. Paragraph (f) of this section 
lists the other energy audit requirements that do not pertain to cost-
effectiveness tests of weatherization materials. Paragraphs (g) and

[[Page 1152]]

(h) of this section describe the use of priority lists and presumptively 
cost-effective general heat waste reduction materials as part of a 
State's energy audit procedures. Paragraph (i) of this section explains 
that a State's energy audit procedures and priority lists must be re-
approved by DOE every five years.
    (b) Only weatherization materials which are listed in appendix A to 
this part and which meet or exceed standards prescribed in appendix A to 
this part may be purchased with funds provided under this part. However, 
DOE may approve an unlisted material upon application from any State.
    (c)(1) A system or technology shall not be considered by DOE to be a 
renewable energy system under this part unless:
    (i) It will result in a reduction in oil or natural gas consumption;
    (ii) It will not result in an increased use of any item which is 
known to be, or reasonably expected to be, environmentally hazardous or 
a threat to public health or safety;
    (iii) Available Federal subsidies do not make such a specification 
unnecessary or inappropriate (in light of the most advantageous 
allocation of economic resources); and
    (iv) If a combustion rated system, it has a thermal efficiency 
rating of at least 75 percent; or, in the case of a solar system, it has 
a thermal efficiency rating of at least 15 percent.
    (2) Any manufacturer may submit a petition to DOE requesting the 
Secretary to certify an item as a renewable energy system.
    (i) Petitions should be submitted to: Weatherization Assistance 
Program, Office of Energy Efficiency and Renewable, Mail Stop EE-2K, 
1000 Independence Avenue, SW., Washington, DC 20585.
    (ii) A petition for certification of an item as a renewable energy 
system must be accompanied by information demonstrating that the item 
meets the criteria in paragraph (c)(1) of this section.
    (iii) DOE may publish a document in the Federal Register that 
invites public comment on a petition.
    (iv) DOE shall notify the petitioner of the Secretary's action on 
the request within one year after the filing of a complete petition, and 
shall publish notice of approvals and denials in the Federal Register.
    (d) Except for materials to eliminate health and safety hazards 
allowable under Sec. 440.18(c)(15), each individual weatherization 
material and package of weatherization materials installed in an 
eligible dwelling unit must be cost-effective. These materials must 
result in energy cost savings over the lifetime of the measure(s), 
discounted to present value, that equal or exceed the cost of materials, 
installation, and on-site supervisory personnel as defined by the 
Department. States have the option of requiring additional related costs 
to be included in the determination of cost-effectiveness. The cost of 
incidental repairs must be included in the cost of the package of 
measures installed in a dwelling.
    (e) The energy audit procedures must assign priorities among 
individual weatherization materials in descending order of their cost-
effectiveness according to paragraph (d) of this section after:
    (1) Adjusting for interaction between architectural and mechanical 
weatherization materials by using generally accepted engineering methods 
to decrease the estimated fuel cost savings for a lower priority 
weatherization material in light of fuel cost savings for a related 
higher priority weatherization material; and
    (2) Eliminating any weatherization materials that are no longer 
cost-effective, as adjusted under paragraph (e)(1) of this section.
    (f) The energy audit procedures also must--
    (1) Compute the cost of fuel saved per year by taking into account 
the climatic data of the area where the dwelling unit is located, where 
the base temperature that determines the number of heating or cooling 
degree days (if used) reasonably approximates conditions when operation 
of heating and cooling equipment is required to maintain comfort, and 
must otherwise use reasonable energy estimating methods and assumptions;
    (2) Determine existing energy use and energy requirements of the 
dwelling

[[Page 1153]]

unit from actual energy bills or by generally accepted engineering 
calculations;
    (3) Address significant heating and cooling needs;
    (4) Make provision for the use of advanced diagnostic and assessment 
techniques which DOE has determined are consistent with sound 
engineering practices;
    (5) Identify health and safety hazards to be abated with DOE funds 
in compliance with the State's DOE-approved health and safety procedures 
under Sec. 440.16(h);
    (6) Treat the dwelling unit as a whole system by examining its 
heating and cooling system, its air exchange system, and its occupants' 
living habits and needs, and making necessary adjustments to the 
priority of weatherization materials with adequate documentation of the 
reasons for such an adjustment; and
    (7) Be specifically approved by DOE for use on each major dwelling 
type that represents a significant portion of the State's weatherization 
program in light of the varying energy audit requirements of different 
dwelling types including single-family dwellings, multi-family 
buildings, and mobile homes.
    (g) For similar dwelling units without unusual energy-consuming 
characteristics, energy audits may be accomplished by using a priority 
list developed by conducting, in compliance with paragraphs (b) through 
(f) of this section, site-specific energy audits of a representative 
subset of these dwelling units. For DOE approval, States must describe 
how the priority list was developed, how the subset of similar homes was 
determined, and circumstances that will require site-specific audits 
rather than the use of the priority lists. States also must provide the 
input data and list of weatherization measures recommended by the energy 
audit software or manual methods for several dwelling units from the 
subset of similar units.
    (h) States may use, as a part of an energy audit, general heat waste 
reduction weatherization materials that DOE has determined to be 
generally cost-effective. States may request approval to use general 
heat waste materials not listed in DOE policy guidance by providing 
documentation of their cost-effectiveness and a description of the 
circumstances under which such materials will be used.
    (i) States must resubmit their energy audit procedures (and priority 
lists, if applicable, under certain conditions) to DOE for approval 
every five years. States must also resubmit to DOE, for approval every 
five years, their list of general heat waste materials in addition to 
those approved by DOE in policy guidance, if applicable. Policy guidance 
will describe the information States must submit to DOE and the 
circumstances that reduce or increase documentation requirements.

Sec. 451.9  Procedures for processing applications.

    (a) Supplemental information. DOE may request supplementary 
information relating to the application.
    (b) Audits. DOE may require the applicant to conduct at its own 
expense and submit an independent audit, or DOE may conduct an audit, to 
verify the number of kilowatt-hours claimed to have been generated and 
sold by the qualified renewable energy facility and for which an 
incentive payment has been requested or made.
    (c) DOE determinations. The Assistant Secretary for Energy 
Efficiency and Renewable Energy shall determine the extent to which 
appropriated funds are available to be obligated under this program for 
each fiscal year. Upon evaluating each application and any other 
relevant information, DOE shall further determine:
    (1) Eligibility of the applicant for receipt of an incentive 
payment, based on the criteria for eligibility specified in this part;
    (2) The number of kilowatt-hours to be used in calculating a 
potential incentive payment, based on the net electric energy generated 
from a qualified

[[Page 1166]]

renewable energy source at the qualified renewable energy facility and 
sold during the prior fiscal year;
    (3) The number of kilowatt-hours to be used in calculating a 
potential additional incentive payment, based on the total quantity of 
accrued energy generated during prior fiscal years;
    (4) The amounts represented by 60 percent of available funds and by 
40 percent of available funds; and
    (5) Whether justification exists for altering the 60:40 payment 
ratio specified in paragraph (e) of this section. If DOE intends to 
modify the 60:40 ratio, the Department shall notify Congress, setting 
forth reasons for such change.
    (d) Calculating payments. Subject to the provisions of paragraph (e) 
of this section, potential incentive payments under this part shall be 
determined by multiplying the number of kilowatt-hours determined under 
Sec. 451.9(c)(2) by 1.5 cents per kilowatt-hour, and adjusting that 
product for inflation for each fiscal year beginning after calendar year 
1993 in the same manner as provided in section 29(d)(2)(B) of the 
Internal Revenue Code of 1986, except that in applying such provisions 
calendar year 1993 shall be substituted for calendar year 1979. Using 
the same procedure, a potential additional payment shall be determined 
for the number of kilowatt-hours determined under paragraph (c)(3) of 
this section. If the sum of these calculated payments does not exceed 
the funds determined to be available by the Assistant Secretary for 
Energy Efficiency and Renewable Energy under Sec. 451.9(c), DOE shall 
make payments to all qualified applicants.
    (e) Insufficient funds. If funds are not sufficient to make full 
incentive payments to all qualified applicants, DOE shall--
    (1) Calculate potential incentive payments, if necessary on a pro 
rata basis, not to exceed 60 percent of available funds to owners or 
operators of qualified renewable energy facilities using solar, wind, 
ocean, geothermal, and closed-loop biomass technologies based on prior 
year energy generation;
    (2) Calculate potential incentive payments, if necessary on a pro 
rata basis, not to exceed 40 percent of available funds to owners or 
operators of all other qualified renewable energy facilities based on 
prior year energy generation;
    (3) If the amounts calculated in paragraph (e)(1) and (2) of this 
section result in one owner group with insufficient funds and one with 
excess funds, allocate excess funds to the owner group with insufficient 
funds and calculate additional incentive payments, on a pro rata basis 
if necessary, to such owners or operators based on prior year energy 
generation.
    (4) If potential payments calculated in paragraphs (e)(1), (2), and 
(3) of this section do not exceed available funding, allocate 60% of 
remaining funds to paragraph (e)(1) recipients and 40% to paragraph 
(e)(2) recipients and calculate additional incentive payments, if 
necessary on a pro rata basis, to owners or operators based on accrued 
energy;
    (5) If the amounts calculated in paragraph (e)(4) of this section 
result in one owner group with insufficient funds and one with excess 
funds, allocate excess funds to the owner group with insufficient funds 
and calculate additional incentive payments, on a pro rata basis if 
necessary, to such owners or operators based on accrued energy.
    (6) Notify Congress if potential payments resulting from paragraphs 
(e)(3) or (5) of this section above will result in alteration of the 
60:40 payment ratio;
    (7) Make incentive payments based on the sum of the amounts 
determined in paragraphs (e)(1) through (5) of this section for each 
applicant;
    (8) Treat the number of kilowatt-hours for which an incentive 
payment is not made as a result of insufficient funds as accrued energy 
for which future incentive payment may be made; and
    (9) Maintain a record of each applicant's accrued energy.
    (f) Notice to applicant. After calculating the amount of the 
incentive payment under paragraphs (e) through (g) of this section, the 
DOE Deciding Official shall then issue a written notice of the 
determination to the applicant--
    (1) Approving the application as eligible for payment and forwarding 
a copy to the DOE Finance Office with a request to pay;

[[Page 1167]]

    (2) Setting forth the calculation of the approved amount of the 
incentive payment; and
    (3) Stating the amount of accrued energy, measured in kilowatt-
hours, for each qualified renewable energy facility, if any, and the 
energy source for same.
    (g) Disqualification. If the application does not meet the 
requirements of this part or some of the kilowatt-hours claimed in the 
application are disallowed as unqualified, the Deciding Official shall 
issue a written notice denying the application in whole or in part with 
an explanation of the basis for denial.

auction eligible cellulosic biofuels producers. The following procedures 
shall be used:
    (a) DOE shall accept only electronic bids received from pre-auction 
eligible cellulosic biofuels producers during the open window 
established in the solicitation. The open window shall consist of a 
single continuous period of at least four hours for each auction.
    (b) Bids shall identify an estimated annual production amount from 
an eligible cellulosic biofuels production facility on a per gallon, 
site, entity, and year specific basis for a consecutive six year 
production period. A bid also may be submitted for additional incentives 
for uncovered production volumes at a site where an award was made in an 
earlier auction round.
    (c) All bids must set forth the methodology used to derive the 
estimates of annual production volumes covered by the bid and the bid 
shall be calculated on a gasoline equivalent volumetric basis using the 
lower heating Btu value of the fuel compared to the lower heating Btu 
value of gasoline.
    (d) All bids will be confidential until 45 days after the close of 
the window for submission of bids for the reverse auction.
    (e) Bid evaluation and incentive awards selection procedures include 
the following:
    (1) After DOE evaluates the bids received during the open window, it 
shall, within 45 days following the close of the open window for 
submission of bids for the reverse auction, announce on DOE's website 
and by direct mail the names of the successful bidders and the terms of 
their bids.
    (2) DOE shall issue awards for the bid production amounts beginning 
with the bidder that submitted the bid for the lowest level of 
production incentive on a per gallon basis.
    (3) In the event of a tie among the lowest bids, preference will be 
given to the lowest tied bidder based on DOE's evaluation of the extent 
to which the tied bids meet the following criteria:
    (i) Demonstrates outstanding potential for local and regional 
economic development;
    (ii) Includes agricultural producers or cooperatives of agricultural 
producers as equity partners in the ventures; and

basis requested in the auction solicitation for each gallon produced and 
sold by the entity during the first six years of operation of its 
eligible cellulosic biofuels production facility.
    (b) Failure to commence production. Except in the circumstance of a 
force majeure event, as solely determined by DOE, failure by an eligible 
cellulosic biofuels producer that made a successful bid to commence 
production of cellulosic biofuels, at the eligible cellulosic biofuels 
production facility that was the subject of the successful bid, by the 
end of the third year after the close of submission of the open window 
of bids for the reverse auction in which it submitted a successful bid, 
shall result in immediate revocation of DOE's award to that producer.
    (c) Failure of the successful bidder to meet annual production 
obligations. Except in the circumstance of a force majeure event, as 
solely determined by DOE, a successful bidder's failure to produce at 
least 50 percent of the volumes specified in its production agreement by 
December 31 of any year covered by the bid shall result in immediate 
revocation of DOE's award; if the successful bidder produces 50 percent 
or more of the volumes set forth in the production agreement on an 
annual basis by December 31 of any year covered by the agreement, any 
production shortfall will be carried forward and added to the successful 
bidder's production obligations for next year covered by the agreement.
    (d) Shortfalls remaining at the end of the production period. If, 
for any reason, by December 31 of the last year of the production 
agreement, the bidder has failed to produce the total production volumes 
for all years covered by the agreement, any such remaining shortfall 
shall be awarded to the bidder with the next lowest bid in the auction 
round for which the award was made. If, however, the next best bidder is 
unable to enter into a production agreement with DOE within 30 days 
after being notified of its award, the shortfall shall be allocated 
instead to the next reverse auction.
    (e) Incentive award limitations. The following limits shall apply to 
awards of cellulosic biofuels production incentives under this part:
    (1) During the first four years after the commencement of the 
program, the incentive shall be limited to $1.00 per gallon. For 
purposes of this limitation, the program shall be deemed to have 
commenced on the date that the first solicitation for a reverse auction 
is issued;
    (2) A per gallon cap over the remaining lifetime of the program of 
$.95 per gallon provided that--
    (i) This cap shall be lowered by $.05 each year commencing the first 
year after annual cellulosic biofuels production in the United States 
exceeds 1 billion gallons;
    (ii) Not more than 25 percent of the funds committed within each 
reverse auction shall be awarded to any single project;
    (iii) Not more than $100 million in production incentives shall be 
awarded in any one calendar year; and
    (iv) Not more than $1 billion in production incentives shall be 
awarded over the lifetime of the program.
    (f) Participation in subsequent auctions. A successful bidder in a 
reverse auction under this part may participate in subsequent reverse 
auctions if the incentives sought will assist the addition of plant 
production capacity for the eligible cellulosic biofuels production 
facility associated with its previously successful bid.

    (g) Transferability of awards. A production incentive award under 
this part may be transferred to a successor entity at the same 
production facility for which the award was made, provided that the 
successor entity meets all eligibility requirements of this part, 
including execution of an agreement with DOE to commence production of 
cellulosic biofuels in commercially significant quantities not later 
than three years of the date that bidding closes on the reverse auction 
in which the predecessor entity submitted a successful bid.

measures, by dividing the estimated total cost of the measure, as 
determined pursuant to Sec. 455.62(d)(3)(ii), by the estimated annual 
cost savings accruing from the measure (adjusted for demand charges), as 
determined pursuant to Sec. 455.62(d)(3)(vi), provided that:
    (i) At least 50 percent of the annual cost savings used in this 
calculation shall be from the cost of the energy to be saved or a higher 
percent if required by a State in its State Plan pursuant to Sec. 
455.20(u)(3); and
    (ii) No more than 50 percent of the annual cost savings used in this 
calculation shall be from other cost savings, such as those resulting 
from energy conservation maintenance and operating procedures related to 
particular energy conservation measures, or from changes in type of fuel 
used, or a lower percent if required by a State in its State Plan 
pursuant to Sec. 455.20(u)(3).
    (2) The simple payback period of each renewable resource energy 
conservation measure shall be calculated, taking into account the 
interactions among the various measures, by dividing the estimated total 
cost of the measure, as determined pursuant to Sec. 455.62(d)(3)(ii), 
by the estimated annual cost savings accruing from the measure taking 
into account at least the annual cost of the non-renewable fuels 
displaced less the annual cost of the renewable fuel, if any, and the 
annual cost of any backup non-renewable fuel needed to operate the 
system, adjusted for demand charges, as determined pursuant to Sec. 
455.62(d)(3)(vi).
    (3) The simple payback period of each energy conservation measure 
designed to shift demand to a period of lower demand and lower cost 
shall be calculated, taking into account the interactions among the 
various measures, by dividing the estimated total cost of the measure, 
as determined pursuant to Sec. 455.62(d)(3)(ii), by the estimated 
annual cost savings accruing from the measure taking into account at 
least the annual cost of the energy used before the measure is installed 
less the estimated annual cost of the energy to be used after the 
measure is installed, adjusted for demand charges, as determined 
pursuant to Sec. 455.62(d)(3)(vi).
    (b) This paragraph applies, in addition to paragraph (a) of this 
section, if the State plan requires the cost effectiveness of an energy 
conservation measure to be determined by life-cycle

[[Page 1186]]

cost analysis or if the applicant requests such an analysis.
    (1) A life-cycle cost analysis, showing a savings-to-investment 
ratio greater than or equal to one over the useful life of the energy 
conservation measure or 15 years, whichever is less, shall be conducted 
in accordance with the requirements set forth in the State Plan pursuant 
to Sec. Sec. 455.20(u)(2), 455.20(u)(3) and Sec. 455.64.
    (2) The resulting savings-to-investment ratio shall be used for the 
purpose of ranking applications.



Sec. 455.64  Life-cycle cost methodology.

    (a) The life-cycle cost methodology under Sec. 455.63(b) of this 
part is a systematic comparison of the relevant significant cost savings 
and costs associated with an energy conservation measure over its 
expected useful life, or other appropriate study period with future cost 
savings and costs discounted to present value. The format for displaying 
life-cycle costs shall be a savings-to-investment ratio.
    (b) An energy conservation measure must be cost effective, and its 
savings-to-investment ratio must be greater than or equal to one no 
earlier than the end of the second year of the study period.
    (c) A savings-to-investment ratio is the ratio of the present value 
of net cost savings attributable to an energy conservation measure to 
the present value of the net increase in investment, maintenance and 
operating, and replacement costs less salvage value or disposal cost 
attributable to that measure over a study period.
    (d) Except for energy conservation measures to shift demand or to 
use renewable energy resources, the numerator of the savings-to-
investment ratio shall include net cost savings, appropriately 
discounted and adjusted for energy cost escalation consistent with 
paragraph (g) of this section, subject to the limitation that the cost 
of the energy to be saved shall constitute at least 50 percent of the 
net cost savings unless the State specifies a higher percent in its 
State plan pursuant to Sec. 455.20(u)(3).
    (e) With respect to energy conservation measures to shift demand or 
to use renewable energy resources, the numerator of the savings-to-
investment ratio shall be net cost savings appropriately discounted and 
adjusted for energy cost escalation consistent with paragraph (g) of 
this section.
    (f) The study period for a life-cycle cost analysis, which may not 
exceed 15 years, shall be the useful life of the energy conservation 
measure or of the energy conservation measure with the longest life (for 
purposes of ranking buildings with multiple energy conservation 
measures).
    (g) The discount rate must equal or exceed the discount rate 
annually provided by DOE under 10 CFR part 436. The energy cost 
escalation rates must not exceed those annually provided by DOE under 10 
CFR part 436.
    (h) Investment costs may be assumed to be a lump sum occurring at 
the beginning of the base year, or to the extent that there are future 
investment costs, discounted to present value.
    (i) The cost of energy and maintenance and operating costs may be 
assumed to begin to accrue at the beginning of the base year or when 
they are actually projected to occur.
    (j) It may be assumed that costs occur in a lump sum at any time 
within the year in which they are incurred.

this part.



                         Subpart I_Cost Sharing



Sec. 455.100  Limits to Federal share.

    Amounts made available under this part, together with any other 
amounts made available from other Federal sources, may not be used to 
pay more than 50 percent of the costs of technical assistance programs 
and energy conservation measures unless the grantee qualifies for the 
exceptions specified in Sec. Sec. 455.141(a), 455.142(a), 455.142(b), 
or for severe hardship assistance specified in Sec. 455.142(c). In

percent.



Sec. 455.101  Borrowing the non-Federal share/title to equipment.

    The non-Federal share of the costs of acquiring and installing 
energy conservation measures may be provided by using financing or other 
forms of borrowed funds, such as those provided by loans and performance 
contracts, even if such financing does not provide for the grantee to 
receive clear title to the equipment being financed until after the 
grant is closed out. However, grantees in such cases must otherwise meet 
all the requirements of this part, and financing and loan agreements and 
performance contracts under this section are subject to the requirements 
of 10 CFR part 600 and the certification requirements under Sec. 
455.111(e). Grantees must receive clear title to the equipment when the 
loan is paid off.



Sec. 455.102  Energy conservation measure cost-share credit.

    To the extent a State provides in its State Plan, DOE may wholly or 
partially credit the costs of the following, with respect to a building, 
toward the required cost-share for an energy conservation measure grant 
in that building:
    (a) A non-Federally funded technical assistance program;

[[Page 1189]]

    (b) A non-Federally funded technical assistance program update to 
comply with Sec. 455.20(q); and
    (c) The non-Federally funded implementation of one or more energy 
conservation measures, which complies with the eligibility criteria set 
forth in Sec. 455.71.



Sec. 455.103  Requirements for applications for credit.

    (a) If a State has provided for credit in its State Plan pursuant to 
Sec. 455.20(w), applications for credit will be considered only when 
the technical assistance programs or updates and the energy conservation 
measure projects for which credit is sought meet the applicable program 
requirements, such as those specified in Sec. 455.61, Sec. 455.62, 
Sec. 455.71, and the relevant sections of 10 CFR part 600, except that 
the project need not comply with the Davis-Bacon Act regarding labor 
standards or wage rates.
    (b) Credit for energy conservation measures will be considered only 
when supported by a technical assistance analysis that meets the 
requirements of Sec. 455.62 and that was performed prior to the 
installation of the energy conservation measures.



Sec. 455.104  Rebates from utilities and other entities.

    (a) Grantees which receive rebates or other monetary considerations 
from utilities or other entities for installing the energy conservation 
measures funded by a grant under this part may use such funds to meet 
their cost- sharing obligations pursuant to Sec. 455.100.
    (b) Where the rebate or monetary consideration does not exceed the 
non-Federal share of the cost of the measures applied for in a grant 
application, grantees are not required to deduct the amount of the 
rebate or monetary consideration from the cost of the measures, and DOE 
does not consider such rebates or monetary considerations to be program 
income which would have to be remitted to DOE upon receipt by the 
grantee.
    (c) Where the rebate or monetary consideration does exceed the non-
Federal share of the cost of the measures applied for in a grant 
application, grantees may use the excess to fund additional measures if 
such measures have been recommended in the technical assistance report. 
If it is not possible to use the excess funding in this way, the grantee 
must reduce the cost--and DOE will reduce the Federal share--by the 
amount of the excess above the non-Federal share.

                    Subpart L_State Responsibilities



Sec. 455.130  State evaluation of grant applications.

    (a) If an application received by a State is reviewed and evaluated 
by that State and determined to be in compliance with subparts E, F, and 
J of this part, Sec. 455.130(b), any additional requirements of the 
approved State Plan, State environmental laws, and other applicable laws 
and regulations, then such application will be eligible for financial 
assistance.
    (b) Concurrent with its evaluation and ranking of grant applications 
pursuant to Sec. 455.131, the State will forward applications for 
technical assistance or for energy conservation measures for schools to 
the State school facilities agency for review and certification that 
each school application is consistent with related State programs for 
educational facilities. For hospitals the certification requirement 
applies only if there is a State requirement for it in which case the 
procedure should be described in the State Plan.



Sec. 455.131  State ranking of grant applications.

    (a) Except as provided by Sec. 455.92 of this part, all eligible 
applications received by the State will be ranked by the State in 
accordance with its approved State Plan.
    (b) For technical assistance programs, buildings shall be ranked in 
descending priority based upon the energy conservation potential, on a 
savings percentage basis, of the building as determined in the energy 
audit or energy use evaluation pursuant to Sec. 455.20(k). Each State 
shall develop separate rankings for all buildings covered by eligible 
applications for:
    (1) Technical assistance programs for units of local government and 
public care institutions and
    (2) Technical assistance programs for schools and hospitals.
    (c) All eligible applications for energy conservation measures 
received will be ranked by the State on building-by-building or a 
measure-by-measure basis. If a State ranks on a building-by-building 
basis, several buildings may be ranked as a single building if the 
application proposes a single energy conservation measure which is 
physically connected to all of the buildings. If a State ranks on a 
measure-by-measure basis, a measure that is physically connected to a 
number of buildings may be ranked as a single measure. Buildings or 
measures shall be ranked in accordance with the procedures established 
by the State Plan on the basis of the information developed during a 
technical assistance program (or its equivalent) for the building and 
the criteria for ranking applications. The criterion set forth in 
paragraph (1) of this subsection shall receive at least 50 percent of 
the weight given to the criteria used to rank applications. Each State 
may assign weights to the other criteria as set forth in the State Plan 
pursuant to Sec. 455.20(e). The criteria for ranking applications are:
    (1) Simple payback or a life-cycle cost analysis, calculated in 
accordance with Sec. 455.63 and Sec. 455.64, as applicable;
    (2) The types and quantities of energy to be saved, including oil, 
natural gas, or electricity, in a priority as established in the 
approved State Plan;
    (3) The types of energy sources to which conversion is proposed, 
including renewable energy;
    (4) The quality of the technical assistance program report; and
    (5) Other factors as determined by the State.
    (d) A State is exempt from the ranking requirements of this section 
when:
    (1) The total amount requested by all applications for schools and 
hospitals for technical assistance and energy conservation measures in a 
given grant program cycle for grants up to 50 percent is less than or 
equal to the funds available to the State for such grants and the total 
amount recommended for

[[Page 1196]]

hardship funding is less than or equal to the amounts available to the 
State for such grants and
    (2) The total amount requested by all applications for buildings 
owned by units of local government and public care institutions in a 
given grant program cycle is less than or equal to the total amount 
allocated to the State for technical assistance program grants in the 
State;
    (e) If a State elects to permit applications for credit pursuant to 
Sec. 455.102, such applications for completed or partially completed 
energy conservation measures shall reflect both the work done and the 
work to be done and will be reviewed and ranked on the basis of the cost 
of all of the measures in the project. The credit shall not exceed the 
non-Federal share of the proposed additional energy conservation 
measures (and the Federal share shall not exceed the cost of the work 
remaining to be done).
    (f) Within the rankings of school and hospital buildings for 
technical assistance and energy conservation measures including 
renewable resource measures to the extent that approvable applications 
are submitted, a State shall initially assure that:
    (1) Schools receive at least 30 percent of the total funds allocated 
for schools and hospitals to the State in any grant program cycle and
    (2) Hospitals receive at least 30 percent of the total funds 
allocated for schools and hospitals to the State in any grant program 
cycle.
    (g) If there are insufficient applications from schools or hospitals 
to cover the respective 30 percent requirements specified in paragraph 
(f) of this section, then the State may recommend use of the remaining 
funds in those allocations for other qualified applicants.



Sec. 455.132  State evaluation of requests for severe hardship
assistance.

    (a) To the extent provided in Sec. 455.30(d), financial assistance 
will be initially available for schools and hospitals experiencing 
severe hardship based upon an applicant's inability to provide the non-
Federal share as specified in the State plan pursuant to Sec. 
455.20(g). This financial assistance will be available only to the 
extent necessary to enable such institutions to participate in the 
program.
    (b) The State shall recommend funds for severe hardship applications 
wholly or partially from the funds reserved in accordance with Sec. 
455.30(d) and as stated in an approved State Plan.
    (c) Applications for Federal funding in excess of the non-Federal 
share in the State plan pursuant to Sec. 455.20(x) based on claims of 
severe hardship shall be given an additional evaluation by the State to 
assess on a quantifiable basis to the maximum extent practicable the 
relative need among eligible institutions. The minimum amount of 
additional Federal funding necessary for the applicant to participate in 
the program will be determined by the State in accordance with the 
procedures established in the State Plan. The primary consideration 
shall be the institution's inability to provide the non-Federal share of 
the project cost as specified in the State plan pursuant to Sec. 
455.20(x). Secondary criteria such as climate, fuel cost and fuel 
availability, borrowing capacity, median family income in the area, and 
other relevant factors as determined by the State may be addressed in 
the State Plan as specified in Sec. 455.20(g).
    (d) A State shall indicate, for those schools and hospitals with the 
highest rankings, determined pursuant to Sec. 455.131(b) and (c):
    (1) The amount of additional hardship funding requested by each 
eligible applicant for each building determined to be in a class of 
severe hardship and
    (2) The amount of hardship funding recommended by the State based 
upon relative need, as determined in accordance with the State Plan, to 
the limit of the hardship funds available. The State must decide on a 
case-by-case basis whether, and to what extent, it will recommend 
hardship funding.
    (e) If there are insufficient applications from hardship applicants 
to cover the 10 percent allocation provided for in Sec. 455.30(d), then 
the State may recommend use of the remaining funds for other qualified 
applicants. The total amount recommended for hardship grants cannot 
exceed the 10 percent limit.

Sec. 455.133  Forwarding of applications from institutions and
coordinating agencies for technical assistance and energy conservation
measure grants.

    (a) Except as provided by Sec. 455.92 of this part, each State 
shall forward all applications recommended for funding within its 
allocation to DOE once each program cycle along with a listing of 
buildings or measures covered by eligible applications for schools, 
hospitals, units of local government, and public care institutions 
ranked by the State if necessary pursuant to the provisions of Sec. 
455.131. If ranking has been employed, the list shall include the 
standings of buildings or measures.
    (1) Measure-by-measure rankings will be recombined for the 
respective buildings with more than one recommended measure and
    (2) Buildings will be consolidated under one grantee application.
    (b) The State shall indicate the amount of financial assistance 
requested by the applicant for each eligible building and, for those 
buildings recommended for funding within the limits of the State's 
allocation, the amount recommended for funding. If the amount 
recommended is less than the amount requested by the applicant, the list 
shall also indicate the reason for that recommendation.
    (c) The State shall indicate that it has reviewed and evaluated all 
of the submitted applications and that those applications meet the 
relevant requirements of the program, and shall certify that 
applications submitted are eligible pursuant to Sec. 455.130(a).



Sec. 455.134  Forwarding of applications for State grants for 
technical assistance, program assistance, and marketing.

    A State eligible to apply for grants for technical assistance, 
program assistance, or marketing, as described in Sec. 455.121, may 
submit such an application to DOE any time after the allocations have 
been announced as part of, or in lieu of, an application for a grant for 
State administrative expenses. Such applications shall provide separate 
narrative descriptions, budgets and appropriate milestone dates, 
covering each activity or program, that are sufficiently detailed to 
enable DOE to reasonably evaluate the application.



Sec. 455.135  State liaison, monitoring, and reporting.

    Each State shall be responsible for:
    (a) Consulting with eligible institutions and coordinating agencies 
representing such institutions in the development of its State Plan;
    (b) Notifying eligible institutions and coordinating agencies of the 
content of the approved State Plan and any amendment to a State Plan;
    (c) Notifying each applicant how the applicant's building or measure 
ranked among other applications, and whether and to what extent its 
application will be recommended for funding or if not to be recommended 
for funding, the specific reasons(s) therefor;
    (d) Certifying that each institution has given its assurance that it 
is willing and able to participate on the basis of any changes in 
amounts recommended for that institution in the State ranking pursuant 
to Sec. 455.131;
    (e) Reporting requirements pursuant to Sec. 455.113; and
    (f) Direct program oversight and monitoring of the activities for 
which grants are awarded as defined in the State Plan. States shall 
immediately notify DOE of any noncompliance or indication thereof.



                         Subpart M_Grant Awards



Sec. 455.140  Approval of applications from institutions and
coordinating agencies for technical assistance and energy 
conservation measures.

    (a) DOE shall review and approve applications submitted by a State 
in accordance with Sec. 455.133 if DOE determines that the applications 
meet the objectives of the Act, and comply with the applicable State 
Plan and the requirements of this part. DOE may disapprove all or any 
portion of an application to the extent funds are not available to carry 
out a program or measure (or portion thereof) contained in the 
application, or for such other reason as DOE may deem appropriate.

[[Page 1198]]

    (b) DOE shall notify a State and the applicant of the final approval 
or disapproval of an application at the earliest practicable date after 
the DOE receipt of the application, and, in the event of disapproval, 
shall include a statement of the reasons therefor.
    (c) An application which has been disapproved for reasons other than 
lack of funds may be amended to correct the cause of its disapproval and 
resubmitted in the same manner as the original application at any time 
within the same grant program cycle. Such an application will be 
considered to the extent funds have not already been designated for 
applicants by the ranking process at the time of resubmittal. However, 
nothing in this provision shall obligate either the State or DOE to take 
final action regarding a resubmitted application within the grant 
program cycle. An application not acted upon may be resubmitted in a 
subsequent grant program cycle.
    (d) DOE shall not provide supplemental funds to cover cost overruns 
or other additional costs beyond those provided for in the original 
grant award for technical assistance projects and shall fund only one 
technical assistance project per building.
    (e) DOE shall not provide supplemental funds to cover cost overruns 
or other additional costs beyond those provided for in the original 
grant award for energy conservation measures funded under a grant in a 
given grant program cycle. DOE shall not provide funds to cover energy 
conservation measures intended to replace energy conservation measures 
funded in an earlier grant cycle unless the State has funds remaining 
after all applications for new energy conservation measures have been 
evaluated and submitted to DOE for funding.
    (f) If provided for in the State Plan, an applicant may reapply for 
a technical assistance program or an energy conservation measure grant 
which was included in a prior grant application but which was not 
implemented and for which no funds were expended.
    (g) An applicant may apply for, and DOE may make, grant awards in 
another grant program cycle for additional energy conservation measures 
which relate to a building which previously received grants for other 
energy conservation measures.
    (h) Funds which become available to a grantee after the installation 
of all approved measures, due to cost underruns in the installed 
measures, may be used by the grantee for additional measures if such 
measures are approved in writing by the State and DOE.
    (i) DOE may fund costs incurred by an applicant for technical 
assistance and energy conservation measure projects after the date of 
the grant application, so long as that date is no earlier than the close 
of the preceding grant program cycle. Such costs may be funded when, in 
the judgment of DOE, the applicant has complied with program 
requirements and the costs incurred are allowable under applicable cost 
principles and the approved project budget. The applicant bears the 
responsibility for the entire project cost unless the application is 
approved by DOE in accordance with this part.
    (j) In addition to the prior approval requirements for project 
changes as specified in the DOE Financial Assistance Rules (10 CFR part 
600), a grantee shall request prior written approval from DOE before:
    (1) Transferring DOE or matching amounts between buildings included 
in an approved application when the State ranks applications on a 
building-by-building basis or
    (2) Transferring DOE or matching amounts between energy conservation 
measures included in an approved application when the State ranks on a 
measure-by-measure basis.



Sec. 455.141  Grant awards for units of local government, public care 
institutions, and coordinating agencies.

    (a) DOE may make grants to units of local government, public care 
institutions, and coordinating agencies representing them for up to 50

474.3 Petroleum-equivalent fuel economy calculation.
474.4 Test procedures.
474.5 Review and update.

Appendix to Part 474--Sample Petroleum-Equivalent Fuel Economy 
          Calculations

    Authority: 49 U.S.C. 32901 et seq.

    Source: 65 FR 36991, June 12, 2000, unless otherwise noted.



Sec. 474.1  Purpose and Scope.

    This part contains procedures for calculating a value for the 
petroleum-equivalent fuel economy of electric vehicles, as required by 
49 U.S.C. 32904(a)(2). The petroleum-equivalent fuel economy value is 
intended to be used by the Environmental Protection Agency in 
calculating corporate average fuel economy values pursuant to 
regulations at 40 CFR Part 600--Fuel Economy of Motor Vehicles.



Sec. 474.2  Definitions.

    For the purposes of this part, the term:
    Combined energy consumption value means the weighted average of the 
Urban Dynamometer Driving Schedule and the Highway Fuel Economy Driving 
Schedule energy consumption values (weighted 55/45 percent, 
respectively), as determined by the Environmental Protection Agency in 
accordance with 40 CFR parts 86 and 600.
    Electric vehicle means a vehicle that is powered by an electric 
motor drawing current from rechargeable storage batteries or other 
portable electrical energy storage devices, provided that:
    (1) Recharge energy must be drawn from a source off the vehicle, 
such as residential electric service; and
    (2) The vehicle must comply with all provisions of the Zero Emission 
Vehicle definition found in 40 CFR 88.104-94(g).
    Highway Fuel Economy Driving Schedule energy consumption value means 
the average number of watt-hours of electrical energy required for an 
electric vehicle to travel one mile of the Highway Fuel Economy Driving 
Schedule, as determined by the Environmental Protection Agency.
    Petroleum equivalency factor means the value specified in Sec. 
474.3(b) of this part, which incorporates the parameters listed in 49 
U.S.C. 32904(a)(2)(B) and is used to calculate petroleum-equivalent fuel 
economy.
    Petroleum-equivalent fuel economy means the value, expressed in 
miles per gallon, that is calculated for an electric vehicle in 
accordance with Sec. 474.3(a) of this part, and reported to the 
Administrator of the Environmental Protection Agency for use in 
determining the vehicle manufacturer's corporate average fuel economy.
    Petroleum-powered accessory means a vehicle accessory (e.g., a cabin 
heater, defroster, and/or air conditioner) that:
    (1) Uses gasoline or diesel fuel as its primary energy source; and
    (2) Meets the requirements for fuel, operation, and emissions in 40 
CFR part 88.104-94(g).
    Urban Dynamometer Driving Schedule energy consumption value means 
the average number of Watt-hours of electrical energy required for an 
electric vehicle to travel one mile of the Urban Dynamometer Driving 
Schedule, as determined by the Environmental Protection Agency.



Sec. 474.3  Petroleum-equivalent fuel economy calculation.

    (a) The petroleum-equivalent fuel economy for an electric vehicle is 
calculated as follows:
    (1) Determine the electric vehicle's Urban Dynamometer Driving 
Schedule energy consumption value and the Highway Fuel Economy Driving 
Schedule energy consumption value in units of Watt-hours per mile;
    (2) Determine the combined energy consumption value by averaging the 
Urban Dynamometer Driving Schedule energy consumption value and the 
Highway Fuel Economy Driving Schedule energy consumption value using a 
weighting of 55 percent urban/45 percent highway; and

[[Page 1212]]

    (3) Calculate the petroleum-equivalent fuel economy by dividing the 
appropriate petroleum-equivalency factor (depending on whether any 
petroleum-powered accessories are installed; see paragraph (b) of this 
section) by the combined energy consumption value, and round to the 
nearest 0.01 miles per gallon.
    (b) The petroleum-equivalency factors for electric vehicles are as 
follows:
    (1) If the electric vehicle does not have any petroleum-powered 
accessories installed, the value of the petroleum equivalency factor is 
82,049 Watt-hours per gallon.
    (2) If the electric vehicle has any petroleum-powered accessories 
installed, the value of the petroleum-equivalency factor is 73,844 Watt-
hours per gallon.



Sec. 474.4  Test procedures.

    (a) The electric vehicle energy consumption values used in the 
calculation of petroleum-equivalent fuel economy under Sec. 474.3 of 
this part will be determined by the Environmental Protection Agency 
using the Highway Fuel Economy Driving Schedule and Urban Dynamometer 
Driving Schedule test cycles at 40 CFR parts 86 and 600.
    (b) The ``Special Test Procedures'' provisions of 40 CFR 86.090-27 
may be used to accommodate any special test procedures required for 
testing the energy consumption of electric vehicles.



Sec. 474.5  Review and Update

    The Department will review part 474 five years after the date of 
publication as a final rule to determine whether any updates and/or 
revisions are necessary. DOE will publish a notice in the Federal 
Register soliciting stakeholder input in this review. The Department 
will publish the findings of the review and any resulting adjustments to 
part 474 in the Federal Register.



  Sec. Appendix to Part 474--Sample Petroleum-Equivalent Fuel Economy 
                              Calculations

    Example 1: An electric vehicle is tested in accordance with 
Environmental Protection Agency procedures and is found to have an Urban 
Dynamometer Driving Schedule energy consumption value of 265 Watt-hours 
per mile and a Highway Fuel Economy Driving Schedule energy consumption 
value of 220 Watt-hours per mile. The vehicle is not equipped with any 
petroleum-powered accessories. The combined electrical energy 
consumption value is determined by averaging the Urban Dynamometer 
Driving Schedule energy consumption value and the Highway Fuel Economy 
Driving Schedule energy consumption value using weighting factors of 55 
percent urban, and 45 percent highway:

combined electrical energy consumption value = (0.55 * urban) + (0.45 * 
          highway) = (0.55 * 265) + (0.45 * 220) = 244.75 Wh/mile

    Since the vehicle does not have any petroleum-powered accessories 
installed, the value of the petroleum equivalency factor is 82,049 Watt-
hours per gallon, and the petroleum-equivalent fuel economy is:

(82,049 Wh/gal) (244.75 Wh/mile) = 335.24 mpg
    Example 2: The vehicle from Example 1 is equipped with an optional 
diesel-fired cabin heater/defroster. For the purposes of this example, 
it is assumed that the electrical efficiency of the vehicle is 
unaffected.
    Since the vehicle has a petroleum-powered accessory installed, the 
value of the petroleum equivalency factor is 73,844 Watt-hours per 
gallon, and the petroleum-equivalent fuel economy is:

(73,844 Wh/gal) (244.75 Wh/mile) = 301.71 mpg

                 Subpart C_Mandatory State Fleet Program



Sec. 490.200  Purpose and scope.

    This subpart sets forth rules implementing the provisions of Section 
507(o) of the Act which requires, subject to some exemptions, that 
certain percentages of new light duty motor vehicles acquired for State 
fleets be alternative fueled vehicles.



Sec. 490.201  Alternative fueled vehicle acquisition mandate schedule.

    (a) Except as otherwise provided in this part, of the new light duty 
motor vehicles acquired annually for State government fleets, including 
agencies thereof but excluding municipal fleets, the following 
percentages shall be alternative fueled vehicles for the following model 
years;
    (1) 10 percent for model year 1997;
    (2) 15 percent for model year 1998;
    (3) 25 percent for model year 1999;
    (4) 50 percent for model year 2000; and
    (5) 75 percent for model year 2001 and thereafter.
    (b) Each State shall calculate its alternative fueled vehicle 
acquisition requirements for the State government fleets, including 
agencies thereof, by applying the alternative fueled vehicle acquisition 
percentages for each model year to the total number of new light duty 
motor vehicles to be acquired during that model year for those fleets.
    (c) If the calculation performed under paragraph (b) of this section 
produces a number that requires the acquisition of a partial vehicle, an 
adjustment to the acquisition number will be made by rounding the number 
of vehicles down the next whole number if the fraction is less than one 
half and by rounding the number of vehicles up to the next whole number 
if the fraction is equal to or greater than one half.
    (d) A State fleet that first becomes subject to this part after 
model year 1997 shall acquire alternative fueled vehicles in the next 
model year at the percentage applicable to that model year according to 
the schedule in paragraph (a) of this section, unless the State is 
granted an exemption or reduction of the acquisition percentage pursuant 
to the procedures and criteria in section 490.204.



Sec. 490.202  Acquisitions satisfying the mandate.

    The following actions within a model year qualify as acquisitions 
for the purpose of compliance with the requirements of section 490.201 
of this part:
    (a) The purchase or lease of an Original Equipment Manufacturer 
light duty vehicle (regardless of the model year of manufacture) that is 
an alternative fueled vehicle and that was not previously under the 
control of the State or State agency;
    (b) The purchase or lease of an after-market converted light duty 
vehicle (regardless of model year of manufacture), that was not 
previously under control of the State or State agency;
    (c) The conversion of a newly purchased or leased light duty vehicle 
to

[[Page 1220]]

operate on alternative fuels within four months after the vehicle is 
acquired for a State fleet; and
    (d) The application of alternative fueled vehicle credits allocated 
under subpart F of this part.

[61 FR 10653, Mar. 14, 1996, as amended at 79 FR 15903, Mar. 21, 2014]



Sec. 490.203  Light Duty Alternative Fueled Vehicle Plan.

    (a) General Provisions. (1) In lieu of meeting its requirements 
under section 490.201 exclusively with acquisitions for State fleets, a 
State may follow a Light Duty Alternative Fueled Vehicle Plan that has 
been approved by DOE under this section.
    (2) Any Light Duty Alternative Fueled Vehicle Plan must provide for 
voluntary acquisitions or conversions, or combinations thereof, by 
State, local, and private fleets that equal or exceed the State's 
alternative fuel vehicle acquisition requirement under section 490.201.
    (3) Any acquisitions of light duty alternative fueled vehicles by 
participants in the State plan may be included for purposes of 
compliance, irrespective of whether the vehicles are in excluded 
categories set forth in section 490.3 of this part.
    (4) Except as provided in paragraph (h) of this section or except 
for a fleet exempt under section 490.204, a State that does not have an 
approved plan in effect under this section is subject to the State fleet 
acquisition percentage requirements of section 490.201.
    (5) If a significant commitment under an approved plan is not met by 
a participant of a plan, the State shall meet its percentage 
requirements under section 490.201 or submit to DOE an amendment to the 
plan for DOE approval.
    (b) Required elements of a plan. Each plan must include the 
following elements:
    (1) Certification by the Governor, or the Governor's designee, that 
the plan meets the requirements of this subpart;
    (2) Identification of State, local and private fleets that will 
participate in the plan;
    (3) Number of new alternative fueled vehicles to be acquired by each 
plan participant;
    (4) A written statement from each plan participant to assure 
commitment;
    (5) A statement of contingency measures by the State to offset any

order to meet the requirements of section 490.201;
    (6) A provision by the State to monitor and verify implementation of 
the plan;
    (7) A provision certifying that all acquisitions and conversions 
under the plan are voluntary and will meet the requirements of Sec. 247 
of the Clean Air Act, as amended (42 U.S.C. 7587) and all applicable 
safety requirements.
    (c) When to submit plan. (1) For model year 1997, a State shall 
submit its plan on or before March 14, 1997.
    (2) Beginning with model year 1998, a State shall submit its plan to 
DOE no later than June 1 prior to the first model year covered by such 
plan.

meets the requirements of this subpart within 60 days of the date of 
receipt of the plan by DOE at the address in paragraph (g)(1) of this 
section.
    (e) Disapproval of plans. If DOE disapproves or requests a State to 
submit additional information, the State may revise and resubmit the 
plan to DOE within a reasonable time.
    (f) How a State may modify an approved plan. If a State determines 
that it cannot successfully implement its plan, it may submit to DOE for 
approval, at any time, the proposed modifications with adequate 
justifications.
    (g) Where to submit plans. (1) A State shall submit to DOE an 
original and two copies of the plan and shall be addressed to the U.S. 
Department of Energy, Office of Energy Efficiency and Renewable Energy, 
EE-33, 1000 Independence Ave., SW., Washington, DC 20585, or to such 
other address as DOE may announce in a Federal Register notice.
    (2) Any requests for modifications shall also be sent to the address 
in paragraph (g)(1) of this section.
    (h) MY 1997 Exemption. (1) On or after September 1, 1996, a State 
shall be deemed automatically exempt from section 490.201 (a)(1) until 
DOE makes a

[[Page 1221]]

final determination on a timely application to approve a plan for model 
year 1997 under this section if the State:
    (i) Has submitted the application; or
    (ii) Has sent a written notice to the Assistant Secretary, at the 
address under paragraph (g)(1) of this section, that it will file such 
an application on or before March 14, 1997.
    (2) During the period of an automatic exemption under this 
paragraph, a State may procure light duty motor vehicles in accordance

Sec. 490.204  Process for granting exemptions.

    (a) To obtain an exemption, in whole or in part, from the vehicle 
acquisition mandate in section 490.201 of this part, a State shall 
submit to DOE a written request for exemption, along with supporting 
documentation which must demonstrate that--
    (1) Alternative fuels that meet the normal requirements and 
practices of the principal business of the State fleet are not available 
from fueling sites that would permit central fueling of fleet vehicles 
in the area in which the vehicles are to be operated; or
    (2) Alternative fueled vehicles that meet the normal requirements 
and practices of the principal business of the State fleet are not 
available for purchase or lease commercially on reasonable terms and 
conditions in the State; or
    (3) The application of such requirements would pose an unreasonable 
financial hardship.
    (b) Requests for exemption must be accompanied by supporting 
documentation, must be submitted no earlier than September 1 following 
the model year for which the exemption is sought and no later than 
January 31 following the model year for which the exemption is sought, 
and will only be considered following submission of the annual report 
under Sec. 490.205.
    (c) Exemptions are granted for one model year only, and they may be 
renewed annually, if supporting documentation is provided.
    (d) Exemptions may be granted in whole or in part. When granting an 
exemption in part, DOE may, depending upon the circumstances, completely 
relieve a State from complying with a portion of the vehicle acquisition 
requirements for a model year, or it may require a State to acquire all 
or some of the exempted vehicles in future model years.
    (e) If a State is seeking an exemption under--
    (1) Paragraph (a)(1) of this section, the types of documentation 
that are to accompany the request must include, but are not limited to, 
maps of vehicle operation zones and maps of locations providing 
alternative fuel; or
    (2) Paragraph (a)(2) of this section, the types of documentation 
that are to accompany the request must include, but are not limited to, 
alternative fueled vehicle purchase or lease requests, a listing of 
vehicles that meet the normal practices and requirements of the State 
fleet, and any other documentation that exhibits good faith efforts to 
acquire alternative fueled vehicles; or
    (3) Paragraph (a)(3) of this section, it must submit a statement 
identifying what portion of the alternative fueled vehicle acquisition 
requirement should be subject to the exemption and describing the 
specific nature of the financial hardship that precludes compliance.
    (f) Requests for exemption shall be addressed to the U.S. Department 
of Energy, Office of Energy Efficiency and Renewable Energy, EE-33, 1000 
Independence Ave., SW., Washington, DC 20585, or to such other address 
as DOE may announce in a Federal Register notice.
    (g) If DOE, in response to a request for exemption, seeks 
clarification or additional information from the State, such 
clarification or additional information must be submitted to DOE in 
accordance with paragraph (f) of this section within 30 days of DOE's 
inquiry. In the event a State does not comply with this timeframe, DOE 
will proceed under paragraph (h) of this section based on the 
documentation provided to date.
    (h) The Assistant Secretary shall provide to the State, within 45 
days of receipt of a request that complies with this section, a written 
determination as to whether the State's request has been granted or 
denied.

[[Page 1222]]

    (i) If the Assistant Secretary denies an exemption, in whole or in 
part, and the State wishes to exhaust administrative remedies, the State 
must appeal within 30 days of the date of the determination, pursuant to 
10 CFR part 1003, subpart C, to the Office of Hearings and Appeals, U.S. 
Department of Energy, 1000 Independence Ave., SW., Washington, DC 20585. 
The Assistant Secretary's determination shall be stayed during the 
pendency of an appeal under this paragraph.

                    Subpart I_Alternative Compliance

    Source: 72 FR 12964, Mar. 20, 2007, unless otherwise noted.



Sec. 490.801  Purpose and scope.

    This subpart implements section 514 of the Act (42 U.S.C. 13263a) 
which permits States and alternative fuel providers to petition for 
alternative compliance waivers from the alternative fueled vehicle 
acquisition requirements in subparts C and D of this part, respectively.



Sec. 490.802  Eligibility for alternative compliance waiver.

    Any State subject to subpart C of this part and any covered person 
subject to subpart D of this part may apply to DOE for a waiver from the 
applicable alternative fueled vehicle acquisition requirements.



Sec. 490.803  Waiver requirements.

    DOE grants a State or covered person a waiver:
    (a) If DOE determines that the State or covered person will achieve 
a reduction in petroleum consumption, through eligible reductions as 
specified in Sec. 490.804 of this subpart, equal to the amount of 
alternative fuel used if the following vehicles were operated 100 
percent of the time on alternative fuel during the model year for which 
a waiver is requested:
    (1) Previously required alternative fueled vehicles in the fleet's 
inventory at the start of the model year for which a waiver is 
requested;
    (2) Alternative fueled vehicles that the State or covered person 
would have been required to acquire in the model year for which a waiver 
is requested, and in previous model years in which a waiver was granted, 
absent any waivers;
    (b) The State or covered person is in compliance with all applicable 
vehicle emission standards established by the Administrator of the 
Environmental Protection Agency under the Clean Air Act (42 U.S.C. 7401 
et seq.); and
    (c) The State or covered person is in compliance with all applicable 
requirements of this subpart.


Sec. 490.804  Eligible reductions in petroleum consumption.

    (a) Motor vehicles. Demonstrated reductions in petroleum consumption 
during the model year for which a waiver is requested that are 
attributable to motor vehicles owned, operated, leased or otherwise 
under the control of a State or covered person are applicable towards 
the petroleum fuel reduction required in Sec. 490.803(a) of this 
subpart.
    (b) Qualified nonroad vehicles. Demonstrated reductions in petroleum 
consumption during the model year for which a waiver is requested that 
are attributable to nonroad vehicles owned, operated, leased or 
otherwise under the control of a State or covered person acquired during 
waiver years are applicable towards the petroleum fuel reduction 
required in Sec. 490.803(a) of this subpart:
    (1) If acquisition of the nonroad vehicles leads directly to the 
establishment or upgrading of refueling or recharging infrastructure 
during a waiver year that would also allow for increased petroleum 
replacement by serving the fleet's on-road light-duty vehicles; and
    (2) To the extent that additional reductions attributable to motor 
vehicles are not reasonably available.
    (c) Rollover of excess petroleum reductions. (1) Upon approval by 
DOE, petroleum fuel use reductions achieved by a fleet in excess of the 
amount required for alternative compliance in a previous model year may 
be applied towards the petroleum fuel use reduction requirement under 
Sec. 490.803(a) in a model year for which a waiver is granted and for 
which the fleet experiences a shortfall.
    (2)(i) A fleet seeking to roll over for future use the petroleum 
fuel use reductions that it achieved in excess of the amount required 
for alternative compliance in a particular model year must make a 
written request to DOE as part of the fleet's annual report required 
under Sec. 490.807 for the model year in which the excess reductions 
were achieved.
    (ii) Following receipt of a request under paragraph (c)(2)(i) of 
this section, DOE will notify the requesting fleet of the amount of 
excess petroleum

[[Page 1235]]

fuel use reductions that DOE has approved for rollover and potential 
application towards the petroleum fuel use reduction requirement in a 
future model year.
    (iii) A fleet seeking to apply excess petroleum fuel use reductions 
rolled over pursuant to paragraph (c)(2)(ii) of this section in a model 
year for which a waiver is granted and for which the fleet experiences a 
shortfall in achieving the petroleum fuel use reduction requirement 
under Sec. 490.803(a) must make a written request to DOE as part of the 
fleet's annual report required under Sec. 490.807. The written request 
must specify the amount of the rollover reductions (in GGE) the fleet 
wishes to have applied and the total balance of rollover reductions (in 
GGE) the fleet possesses.
    (3)(i) In considering a written request to apply rollover reductions 
under paragraph (c)(2)(iii) of this section, DOE may seek from the fleet 
additional information about the fleet and its operations.
    (ii) Upon approving a request to apply rollover reductions, DOE will 
apply the approved rollover reductions only to the extent that other 
reductions in petroleum consumption through any of the means set forth 
in paragraphs (a) and (b) of this section were not reasonably 
achievable.
    (4) Excess petroleum reductions are not tradable.
    (d) Ineligible reductions. The petroleum reduction plan required by 
paragraph (c)(4) of this section must not include reductions in 
petroleum attributable to incentives for third parties to reduce their 
petroleum use, petroleum reductions that are not transportation-related, 
or petroleum reductions attributable to non-qualified nonroad vehicles.

[72 FR 12964, Mar. 20, 2007, as amended at 79 FR 15907, Mar. 21, 2014]
