UL vs. ETL Product Testing and Listing
Occasionally we are asked about the differences between the use and acceptance of ETL product certification versus UL certification, here is a review of the two certification marks.
What is the difference between the UL and ETL listed marks?
Both UL and ETL marks demonstrate that the product with the mark has met the minimum requirements of widely accepted product safety standards determined through independent testing of a Nationally Recognized Testing Laboratory (NRTL). As a condition of the product testing, the manufacturer agrees to regular follow-up, on-site inspections to verify continued compliance. The only difference between the UL and ETL marks are in the services of the testing laboratory.
What is an NRTL?
A Nationally Recognized Testing Laboratory (NRTL) is an independent laboratory recognized by the Occupational Safety and Health Administration (OSHA) to test products to the specifications of applicable product safety standards. An NRTL’s function is to provide independent evaluation, testing and certification of any electrically operated and gas and oil-fired products.
Are manufacturers required to use UL for product testing?
No. The only major requirement is that the laboratory performing the testing is an OSHA-recognized NRTL. The ETL Listed mark shows compliance with product safety standards.
Do local Inspectors know the ETL listed mark?
Yes. The ETL listed mark is recognized by local inspectors and AHJ’s in North America and much of South America. The ETL listed mark is accepted alternative to UL and is widely acknowledged as proof of product compliance.
