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 -- Organizational Data, applicant's background, history, ownership, testing locations and external organizations used for technical support; Section 4 -- Affiliation, statement of independence; Section 5 -- Personnel, numbers and job descriptions of and training programs for technical staff, identification and qualifications of key personnel; Section 6 -- Services Provided, services provided certification marks, reports and records, follow-up inspection program and testing, and various programs involving client participation; Section 7 -- Testing Experience, testing experience, standards writing activity, and identification of various accreditations; Section 8 -- Control Programs, quality improvement system including Quality Control Manual, recording and control of data, supervision of samples, access security system, test procedures, lab personnel qualifications and test equipment records, standards, codes and regulations distribution, and uniform requirements interpretations; Section 9 -- Appeals Procedures/Procedures and Reports, appeals system, and product field reports; Section 10 -- Test Equipment, appropriateness and calibration of test equipment; Section 11 -- Facilities, size and adequacy of each facility; and Section 12 -- Supplemental Information -- representative NRTL program form.

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 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 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.
