It`s not uncommon to have questions about these standards - What does UL listed mean? What does ETL listed mean? What`s the difference? - so Triad would like to clear some of the confusion.
Underwriters Laboratories (UL) is a Nationally Recognized Testing Laboratory (NRTL) recognized by the Occupational Safety and Health Administration (OSHA). As an NRTL, UL devises, publishes, updates, and maintains minimal standards that certain types of products - magnetic components, other electronics, plastics, potable water, and so on - should maintain.
UL Recognized products are products designed explicitly as a part of a larger product - for example, a power transformer designed to be used in a PC - that meet all standards that are relevant to it in its particular end use. Triad products can be UL Listed or Recognized to any number of standards.
Other NRTLs that are available include, but are not limited to, the Canadian Standards Association (CSA), the British Standards Institution (BSI), VDE, and the British Approvals Board for Telecommunications (BABT).
Thomas Edison started the Lamp Testing Bureau to test lightbulbs for safety in 1896. Later renamed Electrical Testing Laboratories (ETL), the company expanded to include testing for Standards for Safety for a wide variety of electronics components and products.
Products that are ETL Listed have been tested at an ETL laboratory and found to meet all applicable Standards for Safety published by relevant NRTLs.
None. Aside from the body that issues the listing, there is absolutely no difference between a UL listing and an ETL listing.
At Shenzhen Pengchu Industry Co.,Ltd, you will find products with ETL listings, and now you know - ETL Listing and UL Listing are exactly the same.
