Both are OSHA-recognized Nationally Recognized Testing Laboratories that test and certify products to the exact same federal safety standards.ETL (owned by Intertek) does not write its own testing standards. Instead, they test products using the exact same safety standards originally developed by UL (Underwriters Laboratories).
