Nationally Recognized Testing Laboratory (NRTL)

As an OSHA Recognized NRTL in the U.S., Intertek is able to test and certify products for its customers

OSHA (Occupational Safety and Health Administration) is a branch of the U.S. Department of Labor. They are primarily responsible for workplace safety. When OSHA created the NRTL Program in 1988, Intertek (known as “Electrical Testing Laboratories” or “ETL” at the time) was quick to gain recognition and began certifying products on behalf of its worldwide clients in 1989.

Today, Intertek has 13 test laboratories across North America, Europe and Asia that are formally recognized as NRTL sites, plus an additional 31 laboratories that are qualified to test products for United States certification under the umbrella of our headquarter NRTL site in Arlington Heights, IL.

In total, Intertek provides 44 testing laboratories around the world to provide fast, local service to its customers. To learn more about our global accreditations, contact or call +1-800-WORLD-LAB (967-5352).
