UL & ETL Listing - What Do They Mean?
What is the difference between the UL Listed and ETL Listed Marks?
Both marks indicate that a product meets the minimum requirements of widely accepted product safety standards, determined through independent testing by a Nationally Recognized Testing Laboratory (NRTL).
Intertek, the laboratory behind the ETL mark, and Underwriters Laboratories Inc. (UL) are both current NRTLs, so both are approved to test to ensure products meet the safety standards outlined by OSHA.
What does it mean to be an NRTL?
The Occupational Health and Safety Administration (OSHA) put in place a program to ensure products meet basic safety standards; it set up the National Recognized Testing Laboratory (NRTL) program so that independent laboratories could evaluate, test and certify electrical and other products.
