Frequently asked questions
ETL stands for Electrical Testing Laboratories.
ETL certification is a mark of product compliance with North American safety standards. It is issued by Intertek, an independent, international organisation that conducts rigorous testing, inspection, and certification services worldwide.
The ETL Listed Mark is an assurance that an electric product has passed safety tests and meets performance standards. The mark indicates that the product has been tested for electrical components and wiring to ensure safety in damp or wet environments. It also means that the product has undergone testing for electromagnetic compatibility (EMC).
Both ETL and UL are Nationally Recognised Testing Laboratories (NRTLs) that are recognised by the Occupational Safety and Health Administration (OSHA). ETL uses the standards set by UL to test products and does not create its own. UL, on the other hand, develops its own standards and tests products against these benchmarks. ETL is often chosen over UL as it tends to be less expensive and quicker.
