What is the Difference Between UL and ETL List?


A: UL and ETL are both what are called Nationally Recognized Testing Laboratories (NRTL). NRTLs are in place to provide independent safety and quality certifications on products. Electrical appliances typically require their certification . Some manufacturers do sell unlisted products; it is very important to check for the UL or ETL mark before purchasing.
UL develops the testing standards and tests to them. ETL tests to UL standards. In order for an inspector to sign off on a permitted installation for LED Lamps, the National Electric Code requires the manufacturers be NRTL listed.

ETL has been certifying electrical products over 100 years.
In fact, the original Electrical Testing Labs (ETL) was founded by Thomas Edison in 1896.
Electrical Testing Labs was formed to address concerns of lamp safety and performance issues.
Edison’s vision was to provide assurance to consumers, through various types of product performance and safety tests.
The basic principles of Edison’s third-party lamp testing methods remain the same today.
Experts monitored lamps and bulbs to determine how long they would burn, the luminous intensity, and if everything burned as it should without combustibility or explosion.

Difference Between UL and ETL Listing


None. Aside from the body that issues the listing, there is absolutely no difference between a UL listing and an ETL listing.

Because Intertek ETL tests products to previously published UL Standards for Safety, products marked as ETL Listed meet exactly the same criteria as those marked UL Listed or UL Recognized.

At Triad, you will find products with UL listings and with ETL listings, and now you know — they are exactly the same.


Zhongpu does use ETL laboratories; Choose ETL laboratory depends on it provides the best value for their service that we can then pass on to our customers.
