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 has applied for renewal of 
its recognition as an NRTL within the specified time frame (application 
dated September 30, 1993) and retains temporary recognition pending 
OSHA's final decision in this renewal process.

Application

    According to the applicant, Underwriters Laboratories Inc., is an 
independent, not-for-profit product safety certification organization, 
which was founded in 1894. UL has requested accreditation for its five 
major domestic certification locations, including its newest facility 
at Camas, Washington, and two overseas subsidiaries.
    Regarding the merits of the application, the applicant contends 
that it meets the requirements of 29 CFR 1910.7 for renewal of its 
recognition to certify products in the areas of testing which it has 
specified.
    Underwriters Laboratories Inc. states that its application 
demonstrates that for each specified item of equipment or material to 
be certified, it has the capability (including proper testing equipment 
and facilities, trained staff, written testing procedures, quality 
control and calibration programs) to perform testing and examination of 
equipment and materials for workplace safety purposes to determine 
conformance with appropriate product test standards.
    It also claims that it supplies, to the extent needed for the 
particular equipment or materials listed, labeled or accepted, the 
following control or services: Implementation of control procedures for 
identifying UL Certified equipment or materials; inspection of the run 
of production of such items at factories; and conducting of field 
inspections.
    UL states, further, that it is 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.
    The applicant maintains that it has effective procedures for 
reports that are objective and without bias; and for handling 
complaints and disputes under a fair and reasonable system.
    In summary, UL claims that it has the experience, expertise, 
personnel, organization, equipment, and facilities suitable for renewal 
of its accreditation as an OSHA Nationally Recognized Testing 
Laboratory.
    UL's application (Exhibit 2A) consisted of the following segments 
which, it states, demonstrate the above claims:
    Section 1--Introduction, purpose and format; Section 2--Scope and 
Application, standards sought for recognition; Section 3--

Facilities

    Underwriters Laboratories Inc. has five main test facilities 
located in the United States, and two subsidiary laboratories in Asia. 
They are located in Northbrook, IL; Melville, NY; Santa Clara, CA; 
Research Triangle Park, NC; Camas, WA; Taipei, Taiwan; and, Hong Kong.
    The Northbrook, Illinois facility contains the corporate 
headquarters and is the center for developing and distributing 
documents for the organization. It consists of three separate testing 
complexes, the largest of which contains the headquarters offices and 
the majority of the testing laboratories. Contained within this complex 
are the Standards Division, Follow-Up Services Division, Legal, 
Engineering Services Division, Administrative Division, Accounting, and 
External Affairs Division. Roughly 36 percent of the approximately 1700 
employees comprise the technical staff at Northbrook.
    All hazardous location testing is conducted at Northbrook. This 
facility, as do each of the others, performs testing and follow-up 
services for certain of UL's client base. Normally, each facility's 
clients are located within their own geographical area.
    Other specifics of the Northbrook facility are contained in the 
Northbrook Report, Exhibit 2B, under headings pertaining to facilities, 
test equipment, calibration program, test and evaluation procedures, 
test reports, records, quality assurance, follow-up listing program, 
personnel, recognized third party testing, manufacturing site data, 
outside rental equipment, and third party contract services. In most 
instances, the procedures at the other four U.S. locations track those 
found at Northbrook, as do many of the procedures at both the Taiwan 
and Hong Kong facilities.
    The Melville, New York facility houses the East and West 
International Inspection Services department that manages the follow-up 
inspections for products manufactured overseas. Each US based UL 
facility has an International Inspection Coordinator who functions on 
behalf of both the East and West International Inspection Services 
(IIS).
    The IIS is divided into two sections for administrative purposes--
Eastern and Western. The Eastern section includes inspection centers in 
Asia, Australasia, Indian subcontinent and Canada. In addition, the 
Eastern Section coordinates the follow-up and engineering services for 
China. The Western section includes Mexico, Central and South America, 
the Caribbean, Africa, Europe, and the Near and Middle East.
    UL maintains its own overseas inspection centers in many countries 
and also contracts out inspections to other inspection services. Many 
of these contracted inspection services have been in place for over 30 
years. The services are performed by private inspection companies, by 
government inspection agencies, or by a quasi-governmental agency 
similar to our Postal Service.
    The facilities located at Research Triangle Park, North Carolina, 
Santa Clara, California and Camas, Washington utilize procedures 
essentially similar to those as Northbrook and normally perform testing 
and follow-up services for clients located within their geographical 
areas.
    The technical staff at Camas, Washington, the newest facility, is 
comprised of some 22 employees. The laboratory conducts electrical/
electronic testing. The equipment not available is purchased or loaned 
to Camas from other UL offices if required for short-term periods.
    The Hong Kong and Taiwan facilities conduct testing and perform 
evaluations for clients located in the Far East. However, a client may 
choose to have the testing and evaluation done at one of the U.S. 
facilities.
    The Hong Kong facility provides testing support for the UL programs 
for clients in Hong Kong, China, and Australasia. This office has been 
open since 1988.
    In the Hong Kong area the testing laboratory and inspection 
services are housed in the same building. UL staff of the Inspection 
and Administration Services monitors the China National Import & Export 
Commodities Inspection Corporation (CCIC) for inspections carried out 
in China, which are controlled out of the UL Melville office. The staff 
also performs the inspections in Hong Kong.
    The UL laboratory in Taiwan has been in existence for over 20 
years, and performs services for clients within its geographical area. 
The Follow-Up Services Office in Taiwan (the Administration and 
Inspection Services Office) has been in existence for about 10 years.
    The latest test standards are supplied from the Northbrook Office 
for both locations.
    Neither facility rents equipments or subcontracts testing. Products 
that cannot be tested because of the lack of equipment are generally 
sent to a UL laboratory facility in the United States.
    Senior management personnel are rotated from stateside appointments 
to positions in both the Hong Kong and the Taiwan offices.
    All official UL records are in English. Some files contain 
translations and notes that are in other languages. Agreements between 
clients and the laboratory are in English. The required files for the 
record system are the same as those required for products that are 
processed through one of the UL laboratories in the United States.
    Specifics of the on-site investigations for all of the facilities 
may be found in the On-Site Review Reports (Surveys), Exhibits 2B and 
2C. Interested persons are invited to review these reports.
    UL also maintains offices in Atlanta, Baltimore, Boston, Dallas, 
Minneapolis, Portland, Norman (OK), and Seattle. Staff at these 
locations provide engineering services to clients in their geographical 
area, and report directly to one of the five domestic offices where 
their work is reviewed.

Internal Controls (Quality Assurance)

    The UL Quality Assurance (QA) Program is documented in a number of 
manuals that address various functions. There is not a single overall 
document called a QA Manual which alone defines the corporate QA 
policy. The Engineering Department Manual (EDM) has many of the 
elements normally associated with a QA Manual and provides general 
corporate direction. Some of the elements that are addressed are: work 
definitions, costing guidelines, agreement forms, files, test waiving, 
follow-up services policy, client-agent relations, products in foreign 
countries, and confidentiality. This document is presently under 
revision. A program for continuous quality improvement is in place. The 
Q-Plus program utilizes an employee team concept for continuous quality 
improvement.
    The Laboratory Operations Manual (LOM) outlines the laboratory 
quality program and establishes minimum guidelines for such functions 
as development of forms, data requirements, equipment maintenance and 
calibration, report reviewing, auditing, identification of applicable 
tests, and corrective action procedures. The LOM also establishes 
policies for test standards, test equipment, qualified personnel, 
laboratory procedures and documentation, and self-monitoring and self-
improvement.
    The Follow-Up Services (FUS) Manual provides guidance for field 
inspectors who monitor product manufacturing under the applicant's FUS 
Agreement. This Manual provides [[Page 16173]] the day-to-day 
operational guidance for inspection personnel. Other major departments 
utilize their own manuals for providing day-to-day direction.
    For the purpose of consistent application of requirements in the 
standards, a program is in place which provides the controls and 
flexibility for developing and interpreting standards. Each location 
has a designated engineer who is responsible for the interpretations 
for a particular standard. One engineer is the primary designated 
engineer, and is responsible for the coordination of all other 
designated engineers as well as insuring the consistency of all 
interpretations.
    Relative to the NRTL program, the Engineering Department and 
Laboratory Operations manuals are the main documents in the UL 
organization. The LOM is considered as corporate policy and its purpose 
is to provide a framework for procedures and controls to assure that 
the requisite degrees of accuracy are achieved.

Programs

    UL operates a variety of services and organizational programs. Some 
of the programs have been in effect for decades, and have provided the 
test and evaluation data for products that have been approved and are 
still being supplied by manufacturers for introduction into the 
workplaces of the United States.
    The following programs have been 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, pertaining to the types of 
programs and procedures that NRTLs may engage in under the OSHA/NRTL 
program. See Exhibits 2C and 2C(1), concerning the survey and 
acceptance of the Camas, Washington facility, dated March 10, 1995, 
which also review and recommend inclusion of the following programs on 
the basis of their conformance to the programs described in 60 FR 
12980, March 9, 1995, ``Nationally Recognized Testing Laboratories; 
Clarification of the Types of Programs and Procedures'' (Exhibit 8).

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 and 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 
previously accepted product. An example is the substitution of a 
comparable switch from a different manufacturer, or the change of 
horsepower of a motor.
    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 [[Page 16174]] 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 CTDP 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.

Audit Structure

    Corporate level audits are performed yearly while site or 
operational audits are performed semi-annually. Many of the documented 
audit programs are relatively new and a long term historical record 
does not exist. UL has an audit schedule listing for 1993 and 1994 that 
has been followed, and addresses various operating units of the 
organization.

Preliminary Finding

    Underwriters Laboratories Incorporated addressed all of the 
criteria which had to be met for recognition as an NRTL in its initial 
application and in its further correspondence. For example, the 
applicant submitted a list of its test equipment and instrumentation; a 
roster of its personnel including resumes of those in key positions and 
copies of position descriptions; a summary of its listing, labeling, 
and follow-up services, including examples; a statement of its 
independence as a testing laboratory; and a discussion of its control 
programs, including the Q-Plus Program and a copy of its Laboratory 
Operations Manual; and descriptions of its calibration system, appeals 
procedure, recordkeeping and operational procedures.
    Nine major areas were examined in depth in carrying out the 
laboratory surveys: facility; test equipment; calibration program; test 
and evaluation procedures; test reports; records; quality assurance 
program; follow-up listing program; and personnel.
    The discrepancies noted by the survey teams in the on-site 
evaluations [Ex. 2B(1)] were adequately resonded to by the applicant 
prior to the preparation of the survey report and are included as a 
integral part of the report.
    With the preparation of the final survey reports of Underwriters 
Laboratories Incorporated, the survey team was satisfied that the 
testing facilities appeared to meet the necessary criteria required by 
the standard, and so noted in the On-Site Review Report (Survey); see 
Ex. 2B.
    Following a review of the application file, and the on-site survey 
reports of the Northbrook, Illinois; Melville, New York; Research 
Triangle Park, North Carolina; Santa Clara, California; Camas, 
Washington; and the subsidiary Taipei, Taiwan, and Hong Kong 
facilities, the NRTL Recognition Program staff concluded that the 
applicant appeared to have met the requirements for renewal of its 
recognition as a Nationally Recognized Testing Laboratory for the above 
noted facilities and, therefore, recommended to the Assistant Secretary 
that the application be preliminarily approved.
    Based upon a review of the completed application file and the 
recommendations of the staff, the Assistant Secretary has made a 
preliminary finding that the Underwriters Laboratories Incorporated 
facilities for which accreditation was requested can meet the 
requirements for recognition (Camas, WA), or renewal of recognition 
(all others noted above), as required by 29 CFR 1910.7.
    All interested members of the public are invited to supply detailed 
reasons and evidence supporting or challenging the sufficiency of the 
applicant's having met the requirements for renewal of its recognition 
as a Nationally Recognized Testing Laboratory, as well as Appendix A, 
of 29 CFR 1910.7. Submission of pertinent written documents and 
exhibits shall be made no later than May 30, 1995, and must be 
addressed to the NRTL Recognition Program, Office of Variance 
Determination, Room N 3653, Occupational Safety and Health 
Administration, U.S. Department of Labor, 200 Constitution Avenue, NW., 
Washington, DC 20210. Copies of the UL application, the laboratory 
survey reports, and all submitted comments, as received, (Docket No. 
NRTL-4-93, are available for inspection and duplication at the Docket 
Office, Room N 2634, Occupational Safety and Health Administration, 
U.S. Department of Labor, at the above address.
    The Assistant Secretary's final decision on whether the applicant 
(Underwriters Laboratories Incorporated) satisfies the requirements for 
renewal of its recognition as an NRTL will be made on the basis of the 
entire record including the public submissions an any further 
proceedings that the Assistant Secretary may consider appropriate in 
accordance with Appendix A of Section 1910.7.

    Signed at Washington, DC this 22nd day of March 1995.
Joseph A. Dear,
Assistant Secretary.
