Protection of Stratospheric Ozone: Revision of Refrigerant 
Recovery and Recycling Equipment Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.


SUMMARY: The Environmental Protection Agency (EPA) is taking direct 
final action on motor vehicle refrigerant recovery and recycling 
equipment standards. Under Clean Air Act Section 609, motor vehicle 
air-conditioning (MVAC) refrigerant handling equipment must be 
certified by the Administrator or an independent organization approved 
by the Administrator and, at a minimum, must be as stringent as the 
standards of the Society of Automotive Engineers (SAE) that are in 
effect as of the date of the enactment of the Clean Air Act Amendments 
of 1990. In 1997, EPA promulgated regulations that required the use of 
SAE Standard J2210, HFC-134a Recycling Equipment for Mobile Air 
Conditioning Systems for certification of MVAC refrigerant handling 
equipment. SAE has replaced Standard J2210 with J2788, Recovery/Recycle 
and Recovery/Recycle/Recharging Equipment for HFC-134a Refrigerant. To 
avoid confusion with an outdated reference, EPA is updating its 
reference to the new SAE standards. This action reflects a change in 
industry standard practice. This action also revises the EPA addresses 
to send equipment certification forms.

DATES: This rule is effective on December 31, 2007 without further 
notice, unless EPA receives adverse comment or a request for public 
hearing by December 10, 2007. If we receive adverse comment or a 
request for a public hearing, we will publish a timely withdrawal in 
the Federal Register informing the public that some or all of the 
amendments in this rule will not take effect.

SUPPLEMENTARY INFORMATION: EPA is publishing this rule without a prior 
proposed rule because we view this as a noncontroversial action and 
anticipate no adverse comment because this action is primarily 
administrative in nature. However, in the ``Proposed Rules'' section of 
today's Federal Register, we are publishing a separate document that 
will serve as the proposed rule to update EPA's reference to an 
obsolete SAE standard, if adverse comments or a request for public 
hearing are received on this direct final rule. We will not institute a 
second comment period on this action. Any parties interested in 
commenting must do so at this time. For further information about 
commenting on this rule, see the ADDRESSES section of this document.
    If EPA receives adverse comment or a request for a public hearing, 
we will publish a timely withdrawal in the Federal Register informing 
the public that this direct final rule will not take effect. We would 
address all public comments in any subsequent final rule based on the 
proposed rule.
    Existing regulations covering specifications for motor vehicle air 
conditioning (MVAC) refrigerant handling equipment reference Society of 
Automotive Engineers (SAE) standards that have become outdated because 
the SAE has issued new updated standards. This action will update 
existing regulations to reference newly updated SAE standards. This 
regulatory action is primarily administrative with no significant 
policy issues.
    Section 609 of the Clean Air Act requires that EPA regulations be 
at least as stringent as SAE J1990 standard. J1990 describes 
refrigerant handling equipment for CFC-12 refrigerant. Since Section 
609's conception, the MVAC sector has transitioned from CFC-12, an 
ozone depleting substance, to HFC-134a, a non-ozone depleting 
substance. Now HFC-134a is the predominant refrigerant in MVACs in the 
United States and around the world. At the start of the transition from 
CFC-12 to HFC-134a, more than 13 years ago, SAE developed standard 
J2210 on HFC-134a refrigerant handling equipment. J2210 described 
standards for HFC-134a refrigerant recovery and recycling machines. At 
the time of transition from CFC-12 to HFC-134a, EPA adopted J2210. Now, 
SAE has updated the standard on HFC-134a refrigerant handling equipment 
from J2210 to J2788. This action updates EPA's reference to SAE's new 
HFC-134a refrigerant handling equipment standards (J2788 in Appendix C 
to Subpart B of Part 82 in the Code of Federal Regulations).

I. Background

A. Statutory Authority

    Title VI of the Clean Air Act (Act) is designed to protect the 
stratospheric ozone layer. Section 609 of the Act requires the 
Administrator to promulgate regulations establishing standards and 
requirements regarding the servicing of MVACs. The Act requires that 
the Administrator establish standards for using MVAC refrigerant 
handling equipment that shall be at least as stringent as the 
applicable standards of SAE in effect as of the date of enactment 
(November 15, 1990).

B. EPA Section 609 Equipment Certification Program

    EPA requires that any person repairing or servicing MVACs shall 
certify to EPA that such person has acquired approved refrigerant 
handling equipment. An independent standards testing organization, 
approved by EPA, certifies equipment as meeting the MVAC refrigerant 
handling equipment standards. At this time, Intertek/ETL and 
Underwriters Laboratories Inc. (UL) have been approved by EPA to 
certify MVAC refrigerant handling equipment.

C. SAE Industry Standards

    EPA refers to the SAE J standards for technical specifications 
related to MVAC servicing issues. SAE's standards are developed through 
international participation and cooperation of MVAC experts from motor 
vehicle manufacturers, MVAC suppliers, chemical manufacturers, 
refrigerant handling equipment manufacturers and other interested 
industry stakeholders. SAE standards are internationally recognized, 
adopted and referenced by all major motor vehicle manufacturers and 
their suppliers. SAE periodically updates their standards to reflect 
changes in industry best practices and/or technology improvements.

II. New Industry Practice and Updated SAE Standard

    Test results from the SAE Improved Mobile Air Conditioning 

[[Page 63492]]

Research Project, an MVAC industry sponsored research project, 
indicated that equipment designed to meet SAE standards J2210 did not 
recover refrigerant from MVAC systems as well as was previously assumed 
(Docket No. EPA-HQ-OAR-2006-0428-0001). As much as 30% of refrigerant 
remained in an MVAC system when J2210 recovery equipment indicated all 
refrigerant had been recovered. MVAC service technicians rely on 
complete refrigerant recovery to refill MVAC systems according to the 
motor vehicle manufacturer specification. In light of sub-standard 
recovery performance, SAE revised their standards to include 
performance standards that ensure an improved standard of refrigerant 
recovery and recharge. SAE replaced standard J2210 with standard J2788 
in October 2006. J2788 encompasses all of J2210, adds standards on 
recharging of MVAC systems, and adds performance standards to improve 
equipment refrigerant recovery performance. Specifically, J2788 sets a 
recharge accuracy standard of 0.5 ounces and requires 95% recovery of 
refrigerant from an MVAC system.
    With this action, EPA is updating its reference to the SAE 
standards at Sec.  82.36. SAE J2210 will no longer exist effective 
December 2007, and will be superseded by J2788. In Section 82.36, 
Approved refrigerant recycling equipment, EPA is updating the reference 
from J2210 to J2788, for recovery/recycling equipment and for recovery/
recycling/recharging equipment. In addition, for purposes of clarity, 
EPA is adding a clause to Section 82.34 (Prohibitions and required 
practices), which specifies that equipment manufactured or imported 
must meet the SAE standards. By updating our reference to SAE's new 
standard J2788, the Agency avoids confusion on the part of the 
refrigerant handling equipment manufacturer, service technician or A/C 
service shop owner who would otherwise face a federal requirement that 
referenced an obsolete standard that conflicts with the new industry 
standard practice established with J2788.
    Currently the regulations under Sec.  82.36 (Approved refrigerant 
recycling equipment) envisage more than just refrigerant recycling and 
include refrigerant recovery. Therefore, to more accurately reflect the 
provisions outlined in that section, EPA is revising the title of Sec.  
82.36 from ``Approved refrigerant recycling equipment'' to ``Approved 
refrigerant handling equipment.''
    While this action updates EPA's reference to SAE's new J2788 
standard, it does not require an immediate replacement of previously 
certified MVAC recovery and recovery/recycling equipment with new J2788 
equipment. Rather, all new MVAC refrigerant handling equipment 
manufactured after December 31, 2007 must be certified to J2788. 
Equipment manufactured after December 31, 2007 that is certified to 
J2210 will not satisfy EPA requirements and cannot be manufactured or 
imported. See Section III below for a discussion on existing inventory 
of equipment certified to J2210.
    A/C service shop owners or technicians may decide to accelerate 
plans to replace old J2210 equipment with the new J2788 equipment 
standard because of the expected refrigerant savings that translate 
into a cost savings. According to the January 2007 Mobile Air 
Conditioning Society Worldwide (MACS) Service Report (Docket No. EPA-
HQ-OAR-2006-0428-0003), the new J2788 equipment will result in a 30 to 
50% refrigerant savings because the equipment will recover more 
refrigerant from an MVAC system. Recovered refrigerant can be recycled 
for future use, rather than buying new refrigerant product.

III. Effective Date

    MVAC recovery/recycling equipment and MVAC recovery/recycling/
recharging equipment manufactured or imported after December 31, 2007 
must be certified by an EPA-approved independent standards testing 
organization to meet the specifications of Appendix C of 40 Code of 
Federal Regulations, Part 82, Subpart B. As explained above, Appendix C 
will now require that such equipment be certified under SAE's updated 
standard J2788. EPA expects that this date provides sufficient time for 
production facilities and distributors to transition to the new SAE 
standards and sell most if not all of their inventory of J2210 
equipment, since SAE released the new J2788 standard in October 2006. 
EPA will allow sales of J2210 equipment stock manufactured before 
January 1, 2008. Although certification of new equipment under SAE 
standard J2788 becomes effective for equipment manufactured or imported 
after December 31, 2007, EPA suggests that equipment manufacturers 
transition to the new equipment standard as soon as feasible.

IV. Revision to Equipment Certification Mailing Address

    EPA Regional Offices maintain the MVAC refrigerant handling 
equipment certification forms sent by equipment owners, but the current 
regulations require equipment purchasers to mail the form to EPA 
Headquarters. EPA Headquarters then must fax or mail every equipment 
certification to the appropriate region, based on the equipment owner's 
place of business. To streamline this process, EPA is amending Sec.  
82.42 so that equipment owners may send their certification forms 
directly to the appropriate EPA region.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and 
is therefore not subject to review under the EO.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden. 
The recordkeeping and reporting requirements included in this action 
are already included in an existing information collection burden. This 
action does not make any changes that would affect burden. However, the 
Office of Management and Budget (OMB) has previously approved the 
information collection requirements contained in the existing 
regulations, 40 CFR part 82, under the provisions of the Paperwork 
Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control 
number 2060-0247, EPA ICR number 1617.05. A copy of the OMB approved 
Information Collection Request (ICR) may be obtained from Susan Auby, 
Collection Strategies Division; U.S. Environmental Protection Agency 
(2822T); 1200 Pennsylvania Ave., NW., Washington, DC 20460 or by 
calling (202) 566-1672. A copy may also BE downloaded from http://www.regulations.gov.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or disclose or 
provide information to or for a Federal agency. This includes the time 
needed to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of

[[Page 63493]]

information; and transmit or otherwise disclose the information.
    An agency may not conduct or sponsor, and a person is not required 
to respond to a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The RFA generally requires an agency to prepare a regulatory 
flexibility analysis of any rule subject to notice and comment 
rulemaking requirements under the Administrative Procedure Act or any 
other statute unless the agency certifies that the rule will not have a 
significant economic impact on a substantial number of small entities 
Small entities include small businesses, small organizations, and small 
governmental jurisdictions. For purposes of assessing the impacts of 
today's rule on small entities, small entity is defined as: (1) A small 
business as defined by the Small Business Administration's (SBA) 
regulations at 13 CFR 121.201; (2) a small governmental jurisdiction 
that is a government of a city, county, town, school district or 
special district with a population of less than 50,000; and (3) a small 
organization that is any not-for-profit enterprise which is 
independently owned and operated and is not dominant in its field.
    After considering the economic impacts of today's rule on small 
entities, we certify that this action will not have a significant 
economic impact on a substantial number of small entities. As MVAC 
service shop owners replace end-of-life refrigerant handling equipment, 
owners will purchase equipment certified to the new SAE standard.

 D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
    EPA has determined that this rule does not contain a Federal 
mandate that may result in expenditures of $100 million or more for 
State, local, and tribal governments, in the aggregate, or the private 
sector in any one year. Today's rule does not affect State, local, or 
tribal governments. The impact of this rule on the private sector will 
be less than $100 million per year. Thus, today's rule is not subject 
to the requirements of sections 202 and 205 of the UMRA. EPA has 
determined that this rule contains no regulatory requirements that 
might significantly or uniquely affect small governments. These changes 
being made by this action are to update EPA's reference to the new SAE 

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    This action does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government, as 
specified in Executive Order 13132. The changes being made by this 
action are to update EPA's reference to the new SAE standards. Thus, 
Executive Order 13132 does not apply to this rule.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 6, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.'' This final rule does not have 
tribal implications, as specified in Executive Order 13175. It does not 
significantly or uniquely affect the communities of Indian tribal 
governments, because this regulation applies directly to facilities 
that use these substances and not to governmental entities. Thus, 
Executive Order 13175 does not apply to this rule.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    Executive Order 13045: ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
to any rule that: (1) Is determined to be ``economically significant'' 
as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate effect on children. If the regulatory action 
meets both criteria, the Agency must evaluate the environmental health 
or safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that are based on health or safety risks, such that 
the analysis required under section 5-501 of the Order has the 
potential to influence the regulation. This rule is not subject to 
Executive Order 13045 because it is based on technology performance and 
not on health or safety risks.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    This rule is not subject to Executive Order 13211, ``Actions 
Concerning Regulations That Significantly Affect

[[Page 63494]]

Energy Supply, Distribution, or Use'' (66 FR 28355 (May 22, 2001)) 
because it is not a significant regulatory action under Executive Order 

I. National Technology Transfer and Advancement Act

    As noted in the proposed rule, Section 12(d) of the National 
Technology Transfer and Advancement Act of 1995 (``NTTAA''), Public Law 
104-113, Section 12(d) (15 U.S.C. 272 note) directs EPA to use 
voluntary consensus standards in regulatory activities unless to do so 
would be inconsistent with applicable law or otherwise impractical. 
Voluntary consensus standards are technical standards (e.g., materials 
specifications, test methods, sampling procedures, and business 
practices) that are developed or adopted by voluntary consensus 
standards bodies. The NTTAA directs EPA to provide Congress, through 
OMB, explanations when the Agency decides not to use available and 
applicable voluntary consensus standards. This rulemaking explicitly 
references technical standards; EPA uses the SAE revision versions of 
J2210. These standards can be obtained from http://www.sae.org/technical/standards/.

J. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A Major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule will be effective December 31, 2007.

5. Appendix C to Subpart B is revised to read as follows:

Appendix C to Subpart B of Part 82--SAE J2788 Standard for Recovery/
Recycle and Recovery/Recycle/Recharging Equipment for HFC-134a 


    This Appendix establishes the specific minimum equipment 
requirements for the recovery/recycling of HFC-134a that has been 
directly removed from, and is intended for reuse in, mobile air-
conditioning systems and recovery/recycling and system recharging of 
recycled, reclaimed or virgin HFC-134a. Establishing such 
specifications will ensure that system operation with recycled HFC-
134a will provide the same level of performance and durability as 
new refrigerant.

1. Scope

    The purpose of this SAE Standard is to establish the specific 
minimum equipment performance requirements for recovery and 
recycling of HFC-134a that has been directly removed from, and is 
intended for reuse in, mobile air-conditioning (A/C) systems. It 
also is intended to establish requirements for equipment used to 
recharge HFC-134a to an accuracy level that meets Section 9 of this 
document and SAE J2099. The requirements apply to the following 
types of service equipment and their specific applications.
    a. Recovery/Recycling Equipment,
    b. Recovery/Recycling--Refrigerant Charging,
    c. Refrigerant Recharging Equipment Only.
    1.1 Improved refrigerant recovery equipment is required to 
ensure adequate refrigerant recovery to reduce emissions and provide 
for accurate recharging of mobile air conditioning systems. 
Therefore, 12 months following the publication date of this 
standard, requirements in this standard supplements and supersedes, 
SAE J2210.

7. Functional Description

    The ability of the equipment to meet the refrigerant recovery 
and recharge specifications of this section shall be determined by 
the test procedures of Section 10.
    7.1 The equipment must be capable of continuous operation in 
ambient temperatures of 10 [deg]C (50 [deg]F) to 49 [deg]C (120 
[deg]F). Continuous is defined as completing recovery/recycle and 
recharge (if applicable) operations with no more than a brief reset 
period between vehicles, and shall not include time delays for 
allowing a system to outgas (which shall be part of the recovery 
period provided by this standard). Continuous may include time out 
for an air purge if necessary, although it is understood that 
extended equipment-off time is preferred to allow NCG and 
refrigerant separation in the supply tank for optimum results.
    7.1.1 The equipment shall be capable of removing a minimum of 
95.0% of the refrigerant from the test system in 30 minutes or less, 
without external heating, or use of any device (such as shields, 
reflectors, special lights, etc.) which could heat components of the 
system. The recovery procedures shall be based on 21 to 24 [deg]C 
(70 to 75 [deg]F) ambient temperature. The test system for 
qualifying shall be a 1.4 kg (3.0 lbs) capacity orifice tube/
accumulator system in a 2005 Chevrolet Suburban with front and rear 
A/C, or the test option described in 10.5, and shall be determined 
by accurately weighing the recovery machine with the resolution and 
accuracy of within 3 g (.006 lb) in the range of the machine's 
weight. The laboratory shall maintain records of the vehicle, 
including its VIN (vehicle identification number).
    7.1.2 However, the preceding shall not preclude a brief period 
of engine operation at fast idle (up to 15 minutes, up to 2000 rpm) 
to circulate refrigerant and oil, and provide some engine and warm-
up of A/C refrigeration components. The laboratory shall monitor 
coolant temperature per the vehicle engine coolant temperature 
sensor, and coolant temperature shall not be allowed to exceed 105 
[deg]C (221 [deg]F). The time required shall not be included in the 
total time of 30 minutes set forth in 7.1.1.
    7.1.3 The refrigerant that is recovered, following oil 
separation, shall be measured and the quantity displayed, accurate 
to within 30 g (1.0 oz). The equipment must include a 
provision for checking the accuracy, per the requirements of 9.1.
    7.2 During recovery operation, the equipment shall provide 
overfill protection to assure that the liquid fill of the storage 
container (which may be integral or external) does not exceed 80% of 
the tank's rated volume at 21 [deg]C per Department of 
Transportation (DOT) Standard, CFR Title 49, Section 173.304 and the 
American Society of Mechanical Engineers.
    7.3 Portable refillable tanks or containers used in conjunction 
with this equipment must be labeled ``HFC-134a (R-134a),'' meet 
applicable Department of Transportation (DOT) or Underwriters 
Laboratories (UL) Standards, and shall incorporate fittings per SAE 
    7.3.1 The cylinder valve shall comply with the standard for 
cylinder valves, UL 1769.
    7.3.2 The pressure relief device shall comply with the Pressure 
Relief Device Standard Part 1--Cylinders for Compressed Gases, CGA 
Pamphlet S-1.1.
    7.3.3 The tank assembly shall be marked to indicate the first 
retest date, which shall be 5 years after the date of manufacture. 
The marking shall indicate that retest must be performed every 
subsequent 5 years. SAE J2296 provides an inspection procedure. The 
marking shall be in letters at least 6 mm (\1/4\ in) high.
    7.3.4 ASME tanks as defined in UL-1963 may be used and are 
exempt from the retest requirements.
    7.3.5 If the machine is designed for recharging, and the 
marketer permits use of a non-refillable refrigerant tank, the 
machine shall include a way to ensure refrigerant remaining in the 
tank (called the ``heel'') to no more than 2% of tank rated capacity 
when the tank is indicated to be empty. This may be done by the 
machine marketer as follows:
     Specify a non-venting procedure, to minimize the amount 
of unused refrigerant remaining in the tank. The machine shall 
include any devices required for the procedure, other than ordinary 
service shop tools and supplies, and include in the operator's 
manual, any instructions.
     Provide an automatic or (with instructions in the 
operator's manual) semi-automatic non-venting procedure with the 
    The laboratory shall test for the 2% capability. For testing 
purposes it may use a refillable tank, minimum 15 lb capacity (6.8 
kg) containing a minimum of 7.5 lbs (3.4 kg) refrigerant. The test 
is as follows:
    a. Weigh the tank at the start of the test, on a scale accurate 
to plus/minus 3 grams, to ensure it contains sufficient refrigerant.
    b. Operate the machine to remove refrigerant from the tank, 
charging into a holding container until the tank is indicated to be 
empty. Continue with the marketer's recommended procedure for the 2% 
    c. Weigh the tank, on a scale accurate to plus/minus 3 grams.
    d. Using the recovery compressor and/or a vacuum pump, draw the 
tank into a vacuum of 9 to 10 inches Mercury (225 to 250 mm 
Mercury). The tank must hold that vacuum with a decay of less than 
10% in 10 minutes. If vacuum decays 10% or more, the procedure shall 
be repeated as necessary to ensure the tank is empty.
    e. Weigh the tank on a scale accurate to plus/minus 3 grams. The 
difference in weight from Steps 3 to 5 shall be within 2% of the 
weight of the amount of refrigerant that is the tanks rated 
    f. This test may be performed at the conclusion of testing in 
10.4 or 10.5. If the machine passes or has passed all other testing 
in this standard, the marketer may make modifications in procedure 
and/or machine operation and retest once at a later date, within 90 
days. If the machine fails the retest, the machine must be 
completely retested per this standard, or may be certified per the 
following alternative. The marketer of the machine may specify use 
of a non-refillable refrigerant tank that provides for recycling 
and/or disposal of the residual refrigerant, in either case in a 
manner that does not vent. Or the marketer may exclude use of a one-
way container, in the machine's operating instructions.
    7.4 All flexible hoses must comply with SAE J2196.
    7.5 Service hoses must have shutoff devices located at the 
connection point to the system being serviced. Any hoses or lines 
connected to refrigerant containers on or in the machine also shall 
have shutoff devices at the connection points, so that the 
containers may be changed without loss of refrigerant. A tank that 
is a permanent installation is exempt from this requirement.
    7.6 The equipment shall separate oil from the refrigerant, 
measure the amount accurate to 20 ml (0.7 oz.), so the technician 
has an accurate basis for adding oil to the system.
    7.6.1 This statement shall be predominately identified in the 
equipment service manual.

    Note: Use only new lubricant to replace the amount removed 
during the recycling process. Used lubricant should be discarded per 
applicable federal, state and local requirements.

8. Testing

    This test procedure and its requirements are to be used to 
determine the ability of the recycling equipment to adequately 
recycle contaminated refrigerant.
    8.1 The equipment shall be able to clean the contaminated 
refrigerant in Sec.  8.3 to the purity level defined in SAE J2099.

[[Page 63497]]

    8.2 The equipment shall be operated in accordance with the 
manufacturer's operating instructions.

8.3 Contaminated HFC-134a (R-134a) Sample

    8.3.1 The standard contaminated refrigerant shall consist of 
liquid HFC-134a with 1300 ppm (by weight) moisture (equivalent to 
saturation at 38 [deg]C, 100 [deg]F), 45000 ppm (by weight) HFC-134a 
compatible lubricant, and 1000 ppm (by weight) of noncondensable 
gases (air). The HFC-134a compatible lubricant referred to in 8.3.1, 
shall be polyalkylene glycol (PAG), ISO 100 such as UCLN or PAG ISO 
46-55, such as Idemitsu or equivalent, which shall contain no more 
than 1000 ppm by weight of moisture. Although the test lubricant is a PAG, to conform to that 
used in the test vehicle system, the equipment manufacturer also 
shall ensure that it is compatible with polyol ester lubricant, such 
as ND 11 as used in electrically driven compressors in some hybrid 

8.4 Test Cycle

    8.4.1 The equipment must be preconditioned by processing 13.6 kg 
(30 lb) of the standard contaminated HFC-134a at an ambient of 21 to 
24 [deg]C (70 to 75 [deg]F) before starting the test cycle. 1.13 kg 
(2.56 lb) samples are to be processed at 5 min intervals. The test 
fixture, depicted in Figure 1, shall be operated at 21 to 24 [deg]C 
(70 to 75 [deg]F).

    8.4.2 Following the preconditioning procedure per 8.4.1, 18.2 kg 
(40 lb) of standard contaminated HFC-134a are to be processed by the 

8.5 Sample Requirements

    8.5.1 Samples of the standard contaminated refrigerant from 
8.3.1 shall be processed as required in 8.6 and shall be analyzed 
after said processing as defined in 8.7, 8.8, and 8.9. Note 
exception for noncondensable gas determination in 8.9.4.

8.6 Equipment Operating Ambient

    8.6.1 The HFC-134a is to be cleaned to the purity level, as 
defined in SAE J2099, with the equipment operating in a stable

[[Page 63498]]

ambient of 10, 21, and 49 [deg]C (50, 70 and 120 [deg]F) while 
processing the samples as defined in 8.4.

8.7 Quantitative Determination of Moisture

    8.7.1 The recycled liquid phase sample of HFC-134a shall be 
analyzed for moisture content via Karl Fischer coulometric 
titration, or an equivalent method. The Karl Fischer apparatus is an 
instrument for precise determination of small amounts of water 
dissolved in liquid and/or gas samples.
    8.7.2 In conducting this test, a weighed sample of 30 to 130 g 
is vaporized directly into the Karl Fischer anolyte. A coulometric 
titration is conducted and the results are reported as parts per 
million moisture (weight).
    8.8 Determination of Percent Lubricant 8.8.1 The amount of 
lubricant in the recycled HFC-134a sample shall be determined via 
gravimetric analysis. The methodology must account for the 
hygroscopicity of the lubricant.
    8.8.2 Following venting of noncondensable gases in accordance 
with the manufacturer's operating instructions, the refrigerant 
container shall be shaken for 5 min prior to extracting samples for 
    8.8.3 A weighed sample of 175 to 225 g of liquid HFC-134a is 
allowed to evaporate at room temperature. The percent lubricant is 
calculated from weights of the original sample and the residue 
remaining after evaporation.

8.9 Noncondensable Gases--Testing for Amount

    8.9.1 The amount of noncondensable gases shall be determined by 
gas chromatography. A sample of vaporized refrigerant liquid shall 
be separated and analyzed by gas chromatography. A Porapak Q column 
at 130 [deg]C (266 [deg]F) and a hot wire detector may be used for 
the analysis.
    8.9.2 This test shall be conducted on liquid phase samples of 
recycled refrigerant taken from a full container as defined in 7.2 
within 30 min following the proper venting of noncondensable gases.
    8.9.3 The liquid phase samples in 8.9.2 shall be vaporized 
completely prior to gas chromatographic analysis.
    8.9.4 This test shall be conducted at 10 and 49 [deg]C (50 and 
120 [deg]F) and may be performed in conjunction with the testing 
defined in 8.6. The equipment shall process at least 13.6 kg (30 lb) 
of standard contaminated refrigerant for this test.
    8.9.5 The equipment shall be capable of charging refrigerant 
into systems with various lubrication types and shall deliver less 
than 1% by weight residual oil during system charge if the machine 
permits oil charging with refrigerant (due to residual oil in the 
service hoses and recovery unit refrigerant circuit from prior 
recovery, diagnostics and oil injection. This shall be determined 
during SAE J2099 testing.)

9. Recharging the System

    9.1 It is the responsibility of the equipment manufacturer to 
ensure that the vacuum removal performance leaves the system 98% 
free of NCGs before recharging, following recovery and recycle under 
the provisions of this document.
    The equipment must be capable of both indicating and recharging 
the system to within 15 g (0.50 oz) of vehicle manufacturer's 
specifications. The laboratory shall test for this capability by 
choosing a charge amount that is within the range of the vehicle 
manufacturer's specifications. The equipment must indicate and 
charge the system with that chosen amount, within 15 g 
(0.5 oz).
    Example: If 500 g is chosen, the actual and indicated charge 
must be 485 to 515 g, with any difference between actual and 
indicated charge within the laboratory scale accuracy requirements 
of this standard. If a scale is used in the machine, the equipment 
manufacturer shall provide a method or service for the technician to 
check scale accuracy, and include any necessary accuracy-checking 
device (such as a calibration weight(s)) with the machine. If a mass 
flow system is used for charge determination, it must maintain 
accuracy equal to the 15 g (0.50 oz) specification. The equipment 
manufacturer shall provide a method for checking accuracy and 
include any necessary accuracy testing device(s) with the machine. 
If the accuracy testing device(s) for a scale or mass flow machine 
includes a consumable, the manufacturer shall include a quantity of 
replacement or refill devices for five years of periodic testing as 
    9.2 If any other system is used for charge determination, such 
as a positive displacement pump, the equipment manufacturer shall 
provide a method and any needed device(s) to check accuracy that is/
are appropriate for its method of operation, including any 
temperature-compensating trim if used.

10. Equipment Test Procedure by Laboratory for Recovery/Recycling and 
Recovery/Recycling/Recharging Machines

    10.1 Preliminary: Ambient (in shop) temperature shall be 21 to 
24 [deg]C (70 to 75 [deg]F). Test vehicle shall be ``overnight 
cold'' (not run for at least eight hours).
    10.2 The machine must have a self-contained provision for 
checking accuracy of the indicated amount of refrigerant recovered 
in liquid or vapor or mixture form(s) from a vehicle system and (if 
applicable) charged into a vehicle, and adjusting if necessary, to 
meet requirements of 9.1, 9.2. Therefore: If the machine uses a 
scale for that purpose, check the accuracy of that scale and make 
any adjustment if necessary. If an alternative method of measuring 
refrigerant is used, follow the equipment manufacturer's procedure 
for ensuring accuracy. Next, move the machine, such as by rolling 
it, along the floor, a minimum of 20 feet (6.1 meters) within 10 
seconds. Follow with the test procedure in 10.3, then 10.4 or 10.5.

10.3 Test Procedure

    If desired, this test procedure may be preceded by engine/system 
operation for up to 15 minutes, up to 2000 rpm.
    1. You must start with an empty system, using this method: (a) 
Operate machine to recover refrigerant, per equipment manufacturer's 
instructions. (b) Deep-vacuum system to a minimum of 710 mm (28 in) 
of mercury. (c) Monitor vacuum for decay, checking every 20 minutes. 
If decay exceeds 75 mm (3 in), deep vacuum the system again. When 
system holds 710 mm (28 in) +0/-75 mm (3 in) of mercury vacuum for 
three hours, it is considered empty.
    2. Place machine on a platform scale with the capacity to weigh 
the recovery/recycle/recharge machine, and with the resolution and 
accuracy of within 3 g (.006 lb) in the range of the 
machine's weight. Weight should include the machine's service hoses 
draped over the machine, and with the machine's oil reservoir 
removed. If necessary to add oil to vehicle system as a result of a 
system operation preparatory to the recovery process, inject the 
needed quantity through the service valve at this time.
    3. Record weight of machine in as weight A.
    4. Reconnect service hoses to the test vehicle.
    5. Follow the equipment manufacturer's specified procedure for 
charging the vehicle manufacturer's recommended amount of 
refrigerant into the system. Note: if this does not apply to the 
machine under test, i.e. a recovery/recycling only machine, the use 
of charging equipment that meets this standard and the platform 
scale shall be used to verify the accuracy of the charge.
    6. Disconnect the service hoses from the test vehicle and drape 
them on the machine. Check and record the weight of the machine. 
Record this weight as weight B. The difference between weight A and 
weight B should be equal to the recommended charge that was 
installed per the machine's display, within 15 g (0.5 oz). If the 
difference is greater than 15 g (3 g), the machine fails 
the charge accuracy test, and no other tests shall be performed at 
that time. The manufacturer must document changes made to improve 
accuracy and furnish them to the laboratory prior to a new test. 
Exception: If the maximum deviation is no more than a total of 20 g, 
the calibration of the scale or other measuring system may be 
rechecked and readjusted once, and the entire test repeated just 

10.4 Recovery Test Using a Vehicle

    1. Following a successful system charge, the system and engine 
shall be run for 15 minutes at 2000 rpm to circulate oil and 
refrigerant, following which engine and system shall rest for eight 
hours. Then the laboratory may begin the recovery test. If the 
machine manufacturer specifies, operate the engine/system for up to 
15 minutes, at up to 2000 rpm, then shut off engine/system.
    2. If the machine has an automatic air purge, disable it. Check 
the weight of the machine with the platform scale (service hoses 
draped over machine, oil reservoir removed). Record the number as 
Weight C. Reinstall oil reservoir if it had been removed in the 
recovery procedure.
    3. Start timer. Connect service hoses to system of test vehicle 
and perform recovery per the equipment manufacturer's instructions. 
The vehicle system service valves' cores must remain in the fittings 
for this procedure.
    4. When recovery is completed, including from service hoses if 
that is part of the recommended procedure, disconnect hoses and 
drape over machine. Stop timer. The

[[Page 63499]]

elapsed time shall be 30.0 minutes or less. If it is in excess of 
this time, the machine fails the test and no retest is allowed. The 
manufacturer must document changes made to the machine to improve 
its performance before a new test is allowed, and furnish them to 
the laboratory.
    5. If the recovery is completed in no more than the 30.0 
minutes, measure the oil level in the reservoir, remove the 
reservoir and then determine the amount of refrigerant recovered, as 
detailed in Nos. 6 and 7: As measured by the machine and also by 
noting the weight of the platform scale, which shall be recorded as 
Weight D.
    6. The platform scale shall indicate that a minimum of 95% of 
the amount charged into the system has been recovered. If the 
platform scale indicates a lower percentage has been recovered, the 
machine fails the recovery test.
    7. The machine display shall indicate that a minimum of 95.0% of 
the amount charged into the system has been recovered, within a 
tolerance of 30 g (1 oz) when compared with the platform 
scale (Weight D minus Weight C). The 30 g (1 oz) tolerance may 
produce a machine display reading that is below the 95.0% recovery. 
If a greater difference between machine and platform scale occurs, 
the machine fails the recovery test.

10.5 Recovery Test Fixture Test Option

    If an equipment manufacturer chooses, as an alternative to the 
actual vehicle, it may certify to SAE J2788 with a laboratory 
fixture that is composed entirely of all the original equipment 
parts of a single model year for the 3.0 lb capacity front/rear A/C 
system in the 2005-07 Chevrolet Suburban. All parts must be those 
OE-specified for one model year system and no parts may be 
eliminated or bypassed from the chosen system, or reproduced by a 
non-OE source. No parts may be added and/or relocated from the OE 
position in the 2005-07 Suburban. No parts may be modified in any 
way that could affect system performance for testing under this 
standard, except adding refrigerant line bends and/or loops to make 
the system more compact. Reducing the total length of the lines, 
however, is not permitted. The fixture system shall be powered by an 
electric motor, run at a speed not to exceed 2000 rpm, and for this 
test option, no system warm-up or equivalent procedure may be used. 
The certifying laboratory shall maintain records of all parts 
purchased, including invoices and payments. The assembly of the 
parts shall, as an outside-the-vehicle package, duplicate the OE 
system and its routing, including bends, except for permitted 
additions of bends and/or loops in refrigerant lines. Aside from the 
absence of engine operation and the limitations posed by the 
standard and the use of the electric motor, the test shall otherwise 
be the same as the test on the Suburban, including test temperature.
