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 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 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 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):
