In 1988, the Occupational Safety & Health Administration (OSHA) created the NRTL program which defines the set of criteria to which a lab could prove itself to be worthy to provide evaluation, testing and certification of electrical products. Nationally Recognized Testing Laboratories have been recognized by OSHA as meeting the legal requirements in 29 CFR 1910.7 to perform safety testing and certification of products covered using consensus based test standards.
What is a NRTL (Nationally Recognized Testing Laboratory)?
A Nationally Recognized Testing Laboratory (NRTL) is an independent third-part laboratory recognized by the United States Occupational Safety and Health Administration (OSHA) to test and certify products to applicable product safety standards.
OSHA requires various types of products, devices, assemblies, or systems that are used in the workplace, to be tested and certified by a third-party organization designated as a Nationally Recognized Testing Laboratories (NRTL). Nationally Recognized Testing Laboratories have been recognized by OSHA as meeting the legal requirements in 29 CFR 1910.7 to perform safety testing and certification of products covered using consensus based test standards.
Due to Eurofins E&E North America’s decade long battle of challenging UL’s dominance of product safety certification, in 1988 OSHA created the NRTL program which defines the set of criteria to which a lab could prove itself to be worthy of NRTL status and ensure that certain types of equipment be tested and certified for their safe use in the workplace. Eurofins became the nation’s first Nationally Recognized Testing Laboratory (NRTL) in the United States.
What are NRTL Standards?
OSHA determines which product standards are to be used as they relate to worker safety. OSHA’s standards contain requirements for NRTL product testing and certification for 39 product types. OSHA requires NRTL approval for many kinds of electrical equipment when they are used in the workplace.
Test standards determined to be appropriate for use under OSHA’s NRTL Program include ANSI, IEEE, NEMA, CSA, and UL standards. The need for UL approvals for product safety compliance is actually a common misconception in the industry. While UL does coordinate standards writing, they are only one of several NRTLs for testing and certification.
