The ETL Mark is proof of product compliance to North American safety standards. Authorities across the US and Canada accept the ETL Listed Mark as proof of product compliance to published industry standards. Retail buyers accept it on products they're sourcing.
To have the right to bear the ETL mark, the product must have been tested by a Nationally Recognized Testing Laboratory (NRTL). A Nationally Recognized Testing Laboratory (NRTL) is an independent laboratory recognized by the American Occupational Safety and Health Administration (OSHA) to test products to the specifications of applicable product safety standards.
Today, Intertek has 14 test laboratories across North America, Europe and Asia that are formally recognized as NRTL sites, plus an additional 22 laboratories that are qualified to test products for North American (USA and Canada) certification under the umbrella of our headquarter NRTL site in Arlington Heights, IL.
