SUPPLEMENTARY INFORMATION:

I. Notice of Final Decision

    OSHA hereby gives notice of the expansion of the scope of 
recognition of UL LLC (UL) as a NRTL. UL's expansion covers the 
addition of three test standards to the NRTL scope of recognition.
    OSHA's recognition of a NRTL signifies that the organization meets 
the requirements specified in 29 CFR 1910.7. Recognition is an 
acknowledgment that the organization can perform independent safety 
testing and certification of the specific products covered within the 
scope of recognition. Each NRTL's scope of recognition includes: (1) 
the type of products the NRTL may test, with each type specified by the 
applicable test standard; and (2) the recognized site(s) that has/have 
the technical capability to perform the product-testing and product-
certification activities for test standards within the NRTL's scope. 
Recognition is not a delegation or grant of government authority; 
however, recognition enables employers to use products approved by the 
NRTL to meet OSHA standards that require product testing and 
certification.
    The agency processes applications by a NRTL for initial recognition 
and for an expansion or renewal of this recognition, following 
requirements in Appendix A to 29 CFR 1910.7. This appendix requires 
that the agency publish two notices in the Federal Register in 
processing an application. In the first notice, OSHA announces the 
application and provides a preliminary finding. In the second notice, 
the agency provides a final decision on the application. These notices 
set forth the NRTL's scope of recognition or modifications of that 
scope. OSHA maintains an informational web page for each NRTL, 
including UL, which details the NRTL's scope of recognition. These 
pages are available from the OSHA website at <a href="http://www.osha.gov/dts/otpca/nrtl/index.html">http://www.osha.gov/dts/otpca/nrtl/index.html</a>.
    UL submitted an application to OSHA for expansion of the NRTL scope 
of recognition on August 8, 2025 (OSHA-2009-0025-0082), requesting the 
addition of three test standards to the NRTL scope of recognition. OSHA 
staff performed a detailed analysis of the application packet and 
reviewed other pertinent information. OSHA did not perform an on-site 
review in response to this application. OSHA staff preliminarily 
determined that OSHA should grant the application for test standard 
expansion.
    OSHA published the preliminary notice announcing UL's expansion 
application in the Federal Register on May 22, 2026 (91 FR 30326). The 
agency requested comments by June 8, 2026, but it received no comments 
in response to this notice.
    To obtain or review copies of all public documents pertaining to 
the UL's application, go to <a href="http://www.regulations.gov">http://www.regulations.gov</a> or contact the 
Docket Office, Occupational Safety and Health Administration, U.S. 
Department of Labor. Docket No. OSHA-2009-0025 contains all materials 
in the record concerning UL's recognition. Contact the OSHA Docket 
Office at (202) 693-2350 (TTY (877) 889-5627) for assistance in 
locating docket submissions.

II. Final Decision and Order

    OSHA staff examined UL's expansion application and examined other 
pertinent information. Based on its review of this evidence, OSHA finds 
that UL meets the requirements of 29 CFR 1910.7 for expansion of its

[[Page 54406]]

recognition, subject to the limitations and conditions listed in this 
notice. OSHA, therefore, is proceeding with this final notice to grant 
UL's expanded scope of recognition. OSHA limits the expansion of UL's 
recognition to include the three additional testing standards. OSHA 
grants UL expansion of the NRTL scope of recognition to include the 
test standards listed below in Table 1.

 Table 1--List of Appropriate Test Standards for Inclusion in UL's NRTL
                          Scope of Recognition
------------------------------------------------------------------------
           Test standard                     Test standard title
------------------------------------------------------------------------
UL 1004-9.........................  Form Wound and Medium Voltage
                                     Rotating Electrical Machines.
UL 979............................  Water Treatment Appliances.
UL 2683 *.........................  Electric Heating Systems for Floor
                                     and Ceiling Installation.
------------------------------------------------------------------------
* Represents the standard that OSHA will add to the NRTL Program's List
  of Appropriate Test Standards.

    OSHA's recognition of any NRTL for a particular test standard is 
limited to equipment or materials for which OSHA standards require 
third-party testing and certification before using them in the 
workplace. Consequently, if a test standard also covers any products 
for which OSHA does not require such testing and certification, a 
NRTL's scope of recognition does not include these products.
    In this notice, OSHA also announces the final decision to add one 
new test standard to the NRTL Program's List of Appropriate Test 
Standards. Table 2 below lists the standard that is new to the NRTL 
Program. OSHA has determined that this test standard is an appropriate 
test standard and will add it to the NRTL Program's List of Appropriate 
Test Standards.

     Table 2--Standard OSHA Is Adding to the NRTL Program's List of
                       Appropriate Test Standards
------------------------------------------------------------------------
           Test standard                     Test standard title
------------------------------------------------------------------------
UL 2683...........................  Electric Heating Systems for Floor
                                     and Ceiling Installation.
------------------------------------------------------------------------

    The American National Standards Institute (ANSI) may approve the 
test standards listed above as American National Standards. However, 
for convenience, we may use the designation of the standards-developing 
organization for the standard as opposed to the ANSI designation. Under 
the NRTL Program's policy (see OSHA Instruction CPL 1-0.3, Appendix C, 
paragraph XIV), any NRTL recognized for a particular test standard may 
use either the proprietary version of the test standard or the ANSI 
version of that standard. Contact ANSI to determine whether a test 
standard is currently ANSI-approved.

A. Conditions

    In addition to those conditions already required by 29 CFR 1910.7, 
UL must abide by the following conditions of the NRTL recognition:
    1. UL must inform OSHA as soon as possible, in writing, of any 
change of ownership, facilities, or key personnel, and of any major 
change in its operations as a NRTL, and provide details of the 
change(s);
    2. UL must meet all the terms of its recognition and comply with 
all OSHA policies pertaining to this recognition; and
    3. UL must continue to meet the requirements for recognition, 
including all previously published conditions on UL's scope of 
recognition, in all areas for which it has recognition.
    Pursuant to the authority in 29 CFR 1910.7, OSHA hereby expands the 
scope of recognition of UL as a NRTL, subject to the limitations and 
conditions specified above. Additionally, OSHA will add one standard to 
the NRTL Program's List of Appropriate Test Standards.

III. Authority and Signature

    Amanda Laihow, Principal Deputy Assistant Secretary of Labor for 
Occupational Safety and Health, authorized the preparation of this 
notice. Accordingly, the agency is issuing this notice pursuant to 29
