[Docket No. NRTL-4-93]

Underwriters Laboratories Inc., Expansion of Recognition

AGENCY: Occupational Safety and Health Administration, Labor.

ACTION: Notice.


SUMMARY: This notice announces the Agency's final decision on the 
application of Underwriters Laboratory Inc. (UL), for expansion of its 
recognition as a Nationally Recognized Testing Laboratory (NRTL) under 
29 CFR 1910.7.

EFFECTIVE DATE: This recognition becomes effective on June 24, 1999 
and, unless modified in accordance with 29 CFR 1910.7, continues in 
effect while UL remains recognized by OSHA as an NRTL.

FOR FURTHER INFORMATION CONTACT: Bernard Pasquet, Office of Technical 
Programs and Coordination Activities, NRTL Program, Occupational Safety 
and Health Administration, U.S. Department of Labor, 200 Constitution 
Avenue, NW, Room N3653, Washington, DC 20210, or phone (202) 693-2110.


Notice of Final Decision

    The Occupational Safety and Health Administration (OSHA) hereby 
gives notice of the expansion of recognition of Underwriters 
Laboratories Inc. (UL) as a Nationally Recognized Testing Laboratory 
(NRTL). UL's expansion covers the use of additional test standards. 
OSHA recognizes an organization as an NRTL and processes applications 
related to such recognitions following requirements in Section 1910.7 
of Title 29, Code of Federal Regulations (29 CFR 1910.7). Appendix A to 
this section requires that OSHA publish this public notice of its final 
decision on an application.

[[Page 33914]]

    UL submitted a request, dated February 5, 1996 (see Exhibit 13A), 
to expand its recognition to use additional test standards. UL then 
supplemented its request on April 1, 1997 (see Exhibit 13B), for 
additional test standards. OSHA published the required notice in the 
Federal Register (62 FR 62359, 11/21/97). The notice included a 
preliminary finding that UL could meet the requirements for expansion 
of its recognition, and OSHA invited public comment on the application 
by January 20, 1998. One comment was received, within the time 
provided, in response to the notice (see Exhibit 15-1). UL responded to 
this comment in its letter dated December 22, 1998 (see Exhibit 16).
    The submitter of the comment expressed five ``concerns,'' and posed 
a number of questions related to them. Most of the concerns relate to 
an alleged deficiency in the UL 2161 (Neon Transformers and Power 
Supplies) test standard. The NRTL Program staff has carefully 
considered these concerns but has concluded that the comment provides 
no basis for withholding approval of this test standard for UL or for 
any other NRTL that has the necessary capabilities.
    UL's previous application as an NRTL covered its renewal of 
recognition (60 FR 16171, 3/29/95), which OSHA granted on 6/29/95 (60 
FR 33852).
    You may obtain or review copies of all public documents pertaining 
to the application by contacting the Docket Office, Occupational Safety 
and Health Administration, U.S. Department of Labor, 200 Constitution 
Avenue, NW, Room N2625, Washington, DC 20210, telephone: (202) 693-
2350. You should refer to Docket No. NRTL-4-93, the permanent record of 
public information on the UL recognition.

recognizes for UL are:

Road, Pei Tou District, Taipei, Taiwan

Final Decision and Order

    The NRTL Program staff has examined the application and other 
pertinent information, and the assessment staff recommended, in a memo 
dated August 19, 1997 (see Exhibit 14), expansion of UL's recognition 
to include the additional test standards. Based upon this examination 
and recommendation, OSHA finds that UL has met the requirements of 29 
CFR 1910.7 for expansion of its recognition to use an additional 174 
test standards, subject to the limitations and conditions listed below. 
Pursuant to the authority in 29 CFR 1910.7, OSHA hereby expands the 
recognition of UL, subject to these limitations and conditions. As is 
the case for any NRTL, UL's recognition is further limited to equipment 
or materials (products) for which OSHA standards require third party 
testing and certification before use in the workplace.


    OSHA hereby expands the recognition of UL for testing and 
certification of products to demonstrate compliance to the following 
174 standards. OSHA has determined that each standard meets the 
requirements for an appropriate test standard prescribed in 29 CFR

its operations as an NRTL, including details;
    UL will continue to meet all the terms of its recognition and will 
always comply with all OSHA policies pertaining to this recognition;
