<<< Nationally Recognized Testing Laboratories (NRTL) Printing Instructions Nationally Recognized Testing Laboratories (NRTL) List of Test Standards Recognized - through 1/1/2007 The list below generally shows the test standard name (i.e., designation and title) in effect on the above “through” date. See OSHA’s informational web page for a particular NRTL to determine which of these standards fall within the NRTL’s scope of recognition. The names of the test standards shown in each of these informational web pages were in effect at the time OSHA recognized the NRTL for the particular standards. For convenience in compiling the list, we generally show the test standard name used by the standards developing organization (SDO). However, many of the test standards shown below are approved as American National Standards by the American National Standards Institute (ANSI). Under our procedures, an NRTL recognized for an ANSI-approved test standard may use either the latest proprietary version or the latest ANSI version of that standard, regardless of which version appears in its list of test standards under OSHA’s informational web page for the NRTL. You may contact ANSI to find out whether or not a test standard is currently ANSI-approved. Any parenthetical information shown at the end of a title only relates to the status of the standard on the above “through” date. If shown as “withdrawn” or “not appropriate” below, OSHA will be removing these standards from each NRTLs scope of recognition. Also see List of Test Standards No Longer Recognized for NRTLs.

applications. These standards are not approved for equipment or materials intended for use in installations that are excluded from the provisions of Subpart S in 29 CFR 1910 by 1910.302(a)(2). (2) This standard is approved for testing and certification of vehicle battery adaptors for use within recreational vehicles and mobile homes. (3) Limited to electrical portions only ** This standard is due to be withdrawn by the standards development organization. However, as of the date shown above, the OSHA NRTL Program staff had not determined whether or not there will be a replacement test standard. Once we make the above determination, OSHA will replace or remove this standard, as appropriate. Note - Testing and certification of gas operated equipment is limited to equipment for use with "liquefied petroleum gas" ("LPG" or "LP-Gas"). | Introduction | NRTLs | FAQs | Application | Fees | Regulation | Directive | Presentation | More | Back to Top www.osha.gov www.dol.gov Contact Us | Freedom of Information Act | Customer Survey Privacy and Security Statement | Disclaimers Occupational Safety & Health Administrations 200 Constitution Avenue, NW Washington, DC 20210 Page last updated: 10/01/2008
