Background

    When OSHA published its standard for NRTLs at 29 CFR 1910.7, it 
temporarily recognized Underwriters Laboratories Incorporated (UL) and 
Factory Mutual Research Corporation (FMRC). Both organizations had 
already been referenced by the Occupational Safety and Health 
Administration (OSHA) as acceptable organizations for testing or 
certifying certain workplace equipment and materials. Appendix A of 
section 1910.7 stated, in part, that Underwriters Laboratories 
Incorporated was recognized temporarily as a nationally recognized 
testing laboratory by the Assistant Secretary for a five-year period 
from June 13, 1988 through June 13, 1993. At the end of this five-year 
period UL was required to apply for renewal of that OSHA recognition 
utilizing certain specified procedures. UL applied for renewal of its 
recognition as an NRTL within the specified time frame (application 
dated September 30, 1992) and retained temporary recognition pending 
OSHA's final decision in this renewal process. The final on-site review 
reports, consisting of on-site evaluations of UL testing facilities, 
including administrative and technical practices, located in 
Northbrook, IL; Melville, L.I., NY; Research Triangle Park, NC; Santa 
Clara, CA; Taipei, Taiwan (2 sites); Hong Kong; and Tokyo, Japan (not 
UL owned) (Exhibit 2B, dated September 14, 1994), and in Camas, WA 
(Exhibit 2C, dated March 10, 1995), and the OSHA staff recommendation, 
were subsequently forwarded to the Assistant Secretary for a 
preliminary finding on the application. A notice of UL's application 
for renewal together with a positive preliminary finding was published 
in the Federal Register on March 29, 1995 (60 FR 16171). Interested 
parties were invited to submit comments.
    There was one response to the Federal Register notice of the UL 
application and preliminary finding (Docket No. NRTL-4-93). The 
response, from UL (Ex. 9-1), suggested that OSHA did not fully and 
correctly identify the scope of UL's recognition.
    UL has a program for testing and evaluation that involves 
independent organizations that supply data to it. UL tests products 
for, and accepts test data from, independent, internationally 
recognized laboratories pursuant to the terms of various memoranda of 
understanding or cooperative agreements. The laboratory developing the 
test data conducts these tests according to the appropriate nationally 
recognized standards. The program requirements include the assessment 
of the laboratory's quality program, physical resources, equipment, 
personnel, independence, and data recording procedures for conformance 
with international and UL criteria. Each laboratory is subject to a 
formal initial assessment to determine its capability and 
qualifications to perform testing on a category-by-category, or 
standard-by-standard basis. Each laboratory facility is reassessed on a 
regular basis to verify continued conformance with program criteria.
    This program must be consistent with the requirements of the second 
procedure titled ``Acceptance of Testing Data From Independent 
Organizations, Other Than NRTLs'', as detailed in the March 9, 1995 
Federal Register document, ``Nationally Recognized Testing 
Laboratories; Clarification of the Types of Programs and Procedures'' 
(60 FR 12980).
    UL also states that it may accept components tested at other 
laboratories after review of the test data and other relevant 
documentation and any additional evaluation necessary. The evaluation 
includes assurance that the other laboratory's performance meets the 
level that UL would provide had it performed the service.
    The Occupational Safety and Health Administration has evaluated the 
entire record in relation to the regulations set out in 29 CFR 1910.7 
and makes the following findings:

Capability

    Section 1910.7(b)(1) states that for each specified item of 
equipment or material to be listed, labeled or 

[[Page 33853]]
accepted, the laboratory must have the capability (including proper 
testing equipment and facilities, trained staff, written testing 
procedures, and calibration and quality control programs) to perform 
appropriate testing.
    The on-site review reports indicate that UL has facilities, 
personnel, and testing equipment which are appropriate for the areas of 
recognition it seeks. The various laboratories have available all of 
the general test equipment to perform the testing required by the 
standards. If any additional test equipment is necessary, it will be 
purchased or leased as required.
    The various UL facilities have adequate equipment calibration 
procedures. Typical departments maintain laboratory equipment logs 
which include information relative to repair, routine maintenance, and 
calibration.
    Published standards, laboratory procedural guides, laboratory 
operations manuals, engineering department manuals, and test data 
sheets collectively specify records that are to be maintained for an 
investigation. Laboratory procedural guides detail the procedures to be 
followed for given tests. Details such as specific equipment (and 
alternates) which UL uses to conduct the test, and instructions 
including steps to be used in conducting the tests, are detailed within 
these documents.
    Where these procedural guides have not yet been developed, 
technicians are guided by the UL standard which illustrates the test, 
their knowledge of tests required for the product, data sheets (which 
contain a ``method'' section and lay out basic procedures), and by 
consultation with the project handler.
    No single quality assurance manual exists as such. The size and 
complexity of UL causes the quality assurance system to be dictated by 
the corporate laboratory operations manuals and the engineering 
department manuals. The engineering department manuals provide 
policies, procedures, definitions, and responsibilities encompassing a 
wide variety of issues.
    The laboratory operations manuals identify areas of 
responsibilities within the laboratory and govern the laboratory 
quality system. They identify policies and describe the procedures and 
controls used by engineering and laboratory staff in performing tests 
and reporting of test results. They also address areas such as the 
identification of applicable tests, maintenance and calibration of 
equipment, procedures and practices for conducting tests, personnel 
training and qualification, data recording, reporting and review, 
maintenance of records, feedback and corrective action procedures, and 
internal audit programs. Such audits are carried out at random and are 
unannounced. Action is taken to correct performance that is below 
acceptable levels. The laboratory operations manuals specify the 
procedures associated with corrective actions, which are initiated 
immediately upon identification of the deficient conditions.
Follow-Up and Field Inspection Procedures

    Section 1910.7(b)(2) requires that the NRTL provide certain follow-
up procedures, to the extent necessary, for the particular equipment or 
material to be listed, labeled, or accepted. These include 
implementation of control procedures for identifying the listed or 
labeled equipment or materials, inspecting the production run at 
factories to assure conformance with test standards, and conducting 
field inspections to monitor and assure the proper use of the label.
    A written follow-up program exists. Field representatives make 
periodic unannounced examinations or tests of products at the factory 
and may, from time to time, select samples from the factory, the open 
market, or elsewhere to be sent to a UL testing station for examination 
or test to determine compliance with UL's requirements. The 
determination of the frequency of audits is documented and depends on 
which of UL's follow-up service is implemented. In any event, a minimum 
of four unannounced visits per year is required.
    The base document for follow-up inspections is the follow-up 
service procedure. This document includes information regarding the use 
of the UL mark on the product and the conduct of follow-up service.
    In situations involving the establishment of follow-up services for 
a new manufacturer or for the addition of a new product category for an 
existing manufacturer, a so-called initial production inspection may be 
required. This inspection is intended to assure that each manufacturer 
of a certified product is producing the product in accordance with the 
requirements of a follow-up service procedure commencing with the very 
first production run. Under this program, the manufacturer may not ship 
products bearing a UL mark until the initial production inspection has 
been successfully completed, and products actually being produced are 
found to comply with the requirements of the follow-up service 
procedure.
    Depending upon the type of service, UL marks are either obtained 
through UL, or manufacturers are provided with a control number for all 
their products under a particular product category and purchase the UL 
mark directly from an authorized printer or supplier once UL has 
evaluated the original label design and authorizes the format of the 
mark. Maintaining control of these marks, as well as varying the issue 
or serial numbers as they are printed, enables UL to monitor and track 
closely the usage of its mark, to whom they have been released, and the 
approximate date of their use.

Independence

    Section 1910.7(b)(3) requires that the NRTL be completely 
independent of employers subject to the tested equipment requirements, 
and of any manufacturers or vendors of equipment or materials being 
tested for these purposes.
    OSHA believes, based upon an examination of the application, that 
Underwriters Laboratories Inc. is independent of employers subject to 
the tested equipment requirements and of any manufacturers or vendors 
of equipment or materials being tested for these purposes, within the 
meaning of 29 CFR 1910.7(b)(3).

Creditable Reports/Complaint Handling

    Section 1910.7(b)(4) provides that an OSHA recognized NRTL must 
maintain effective procedures for producing creditable findings and 
reports that are objective and without bias, as well as for handling 
complaints and disputes under a fair and reasonable system.
    UL's application as well as the on-site review reports indicate 
that UL does maintain effective procedures for producing creditable 
findings and reports that are objective.
    Published standards, laboratory procedural guides, laboratory 
operations manuals, engineering department manuals, and test data 
sheets collectively specify records that are to be maintained for an 
investigation.
    Certification reports contain the following information: name and 
address of the applicant; name and address of the testing location if 
different from the laboratory; a unique identifier along with an issue 
date and file number for the report; a detailed description of the 
product including drawings and photographs; specific conditions for use 
of the product when needed; construction and testing narratives which 
describe how the 

[[Page 33854]]
product complies with the standard; a description of the testing 
performed and the results of the tests; a statement of measurement 
uncertainty when appropriate; and an explanation of rationale for any 
deviations, additions or exclusions from the standard.
    Preparation of the certification report preparation is the 
responsibility of the project engineer. A complete review is conducted 
by a second engineer. Signatures of the responsible engineer and 
reviewer, along with other staff involved in the report preparation, 
appear in the report. Signatures of laboratory staff involved in the 
testing and data collection appear on the data sheets.
    As to complaint handling, if clients disagree with a decision 
relating to engineering or inspection they can present and discuss 
their views with the involved engineer, field representative or 
supervisor in an effort to resolve the disagreement. If the matter 
cannot be satisfactorily resolved at that level, they are free to 
appeal up through the managerial chain to the office of the president 
of UL.
    Review procedures are also in place to address complaints from end 
users and others, and are described in UL's field report program.
Test Standards

    Section 1910.7 requires that an NRTL use ``appropriate test 
standards'', which are defined, in part, to include any standard that 
is currently designated as an American National Standards Institute 
(ANSI) safety designated product standard or an American Society for 
Testing and Materials (ASTM) test standard used for evaluation of 
products or materials. As to the non-ANSI, UL test standards for which 
UL has applied to test products to, OSHA previously had examined the 
status of the Underwriters Laboratories Inc. Standards for Safety and, 
in particular, the method of their development, revision and 
implementation, and had determined that they are appropriate test 
standards under the criteria described in 29 CFR 1910.7(c) (1), (2), 
and (3). That is, these standards specify the safety requirements for 
specific equipment or classes of equipment and are recognized in the 
United States as safety standards providing adequate levels of safety; 
they are compatible and remain current with periodic revisions of 
applicable national codes and installation standards; and they are 
developed by a standards developing organization under a method 
providing for input and consideration of views of industry groups, 
experts, users, consumers, governmental authorities, and others having 
broad experience in the safety fields involved.

Programs

    As discussed in the Federal Register notice (60 FR 16171), UL 
operates a variety of services and organizational programs. The 
following programs were previously examined and found to be acceptable 
to OSHA on the basis of the procedures and specific criteria as 
detailed in 60 FR 12980, March 9, 1995, ``Nationally Recognized Testing 
Laboratories; Clarification of the Types of Programs and Procedures'' 
(Exhibit 8), describing the types of programs and procedures that NRTLs 
may engage in under the OSHA/NRTL program.
    Basic Program--This program is one in which UL performs all of the 
necessary product testing and evaluation in-house prior to issuing a 
certification.
    Witnessed Test Data Program--This program involves the use of UL 
Technical Personnel at a manufacturer's test site to witness testing 
for products that will be listed by UL. The manufacturer's facilities 
used for this purpose are qualified by the UL engineering department. 
The follow-up program is the normal one for that product and 
manufacturer (Ex. 2B, Santa Clara Report, Section 11).
    Client Agent Program (CAP)--This program qualifies intermediaries 
that interface between UL and the client. This usually involves 
overseas clients utilizing US based agents. This program qualifies the 
intermediaries in administrative areas, technical areas, or in a 
combination of both. An intermediary that is qualified in the technical 
areas can perform testing on behalf of the client. The Client Agent 
Program does not prohibit an agent from providing technical advice on 
modifications to the product in order to meet the requirements of the 
standard. However, the CAP program is not intended to qualify agents in 
providing technical advice to clients. Administratively qualified 
intermediaries provide documentation, drawing, and translation support 
for the client.
    China National Import & Export Commodities Inspection Corporation 
(CCIC) Inspection Program--The CCIC is a Chinese government 
organization that is retained by the UL Inspection Services to perform 
follow-up inspections in China. This inspection program is under the 
oversight control of UL personnel through the Hong Kong facility, and 
the International Inspection Services Department (Ex. 2b, Melville 
Report, Sections 8 & 13).
    National Certification Body (NCB)--Underwriters Laboratories is one 
of five NRTLs that are participants in the International 
Electrotechnical Commission (IEC) Certification Body (CB) Scheme. This 
is an international program that allows laboratories accredited as 
Certified Bodies to exchange test reports with each other during the 
process of certifying products. The IEC has allowed NRTLs to 
participate in this Scheme because they have been accredited by OSHA. 
The IEC requires governmental oversight for participants.
    Client Test Data Program (CTDP)--This program is the most 
extensively used and the basic program that involves client 
participation. This program involves the systematic qualification of 
the client by reviewing their laboratory, environmental controls, 
testing instrumentation, electrical power system, the client personnel 
involved in the program, the access to the latest UL standards, mutual 
testing, confidence building and the correlation of the testing 
packages with UL test results. Specific test information is required to 
be submitted and UL performs verification testing at intervals not 
known by the participant. There is no change in surveillance conducted 
by UL's follow-up services. There is an additional review conducted by 
UL engineering personnel that is conducted at least yearly to assess 
the participant's continued capability to be in the program. (See Ex. 
2B, Research Triangle Park and Santa Clara Reports, Section 11).
    Compliance Management and Product Assurance Program (COMPASS)--This 
program is a voluntary process that allows qualified manufacturers that 
have successfully utilized the CTDP Program to perform limited self 
evaluation and testing within specified categories.
    For minor changes to already listed products, the client reviews 
the changes and performs any needed tests, and continues to use the 
listing mark. The client submits the documentation to UL for review. If 
the product does not comply, the manufacturer is required to remove the 
UL marks. This procedure for handling minor changes was designed to 
handle the real life situations, such as a purchasing department 
electing to purchase an alternate switch. Rather than wait for a 
variation notice to be issued by UL's follow-up services 
representative, this path serves to keep the client and UL in close 
contact between inspections. Minor changes are defined as modifications 
which involve the use of an alternate or optional component in a 

[[Page 33855]]
previously accepted product. An example is the substitution of a 
comparable switch from a different manufacturer.
    For major changes or new products the client must submit a sample 
and all documentation to UL for review. Depending upon the situation, 
UL may determine that the nature of the change and experience with the 
client and testing associated are such that additional verification 
testing is not necessary. In this situation, UL will authorize the use 
of the listing mark.
    UL may determine that immediate verification testing is not needed. 
In this situation, the authorization to use the Listing mark is given 
but verification testing is conducted later. In all cases, verification 
testing is conducted for new products. In all situations where 
verification testing is needed, if correlation does not exist, the 
listing marks must be removed.
    The follow-up program and engineering department audits are the 
same as with CTDP, and an additional audit of the client's quality 
system is performed. Both CDTP and COMPASS involve UL making a 
determination of the compliance of the product with the standard at 
some point in the process. (See Ex. 2B, Research Triangle Park and 
Santa Clara Reports, Section 11).
    Total Certification Program (TCP)--This program parallels the 
manufacturer and UL in a combined evaluation of products. This is in 
contrast to the sequential process that is used under the COMPASS 
program where the manufacturer tests and evaluates and then submits the 
information to UL.
    The program involves the testing and evaluation of a product by the 
manufacturer, and also the manufacturer's determination of compliance 
with a standard. The manufacturer is subject to continuous involvement 
with UL throughout the design and production of the product. UL 
conducts regular audits throughout the process including verification 
testing. Similar to the COMPASS program, the manufacturer must qualify 
for this program by demonstrating the ability to test and evaluate a 
product and it must have a viable quality assurance program, in 
addition to having the personnel and equipment to provide creditable 
results. In all cases, it is UL who authorizes the use of the listing 
mark. The manufacturer is audited four times a year by the UL 
engineering staff, and twice a year the manufacturer's quality 
assurance program is reviewed. Follow-up inspectors continue to conduct 
follow-ups.

Final Decision and Order

    Based upon a preponderance of the evidence resulting from an 
examination of the complete application, the supporting documentation, 
and the OSHA staff finding including the on-site reports, OSHA finds 
that Underwriters Laboratories, Inc. has met the requirements of 29 CFR 
1910.7 to have its recognition renewed by OSHA as a Nationally 
Recognized Testing Laboratory to test and certify certain equipment or 
materials.
    Pursuant to the authority in 29 CFR 1910.7, Underwriters 
Laboratories', Inc. recognition as a Nationally Recognized Testing 
Laboratory is hereby renewed subject to the conditions listed below. 
This recognition is limited to equipment or materials which, under 29 
CFR part 1910, require testing, listing, labeling, approval, 
acceptance, or certification, by a Nationally Recognized Testing 
Laboratory. This recognition is limited to the use of the following 
test standards for the testing and certification of equipment or 
materials included within the scope of these standards.
    UL has stated that all the standards in these categories are used 
to test equipment or materials which may be used in environments under 
OSHA's jurisdiction. These standards are all considered appropriate 
test standards under 29 CFR 1910.7(c):
