What is UL Listed Mean?

In the course of some project developments, many people may request products to be UL certified, requiring the placement of UL labels on the products. Many people are curious about what UL certification is.

UL stands for Underwriters Laboratories Inc., which is an American testing and certification organization. It was originally an insurance industry organization but is now an independent non-profit entity. UL tests electrical components and equipment for potential hazards.

A product with UL certification means that the product has undergone testing by UL and meets its safety requirements, addressing risks such as fire or electrical hazards.

UL Listing Marks are composed of four elements:
1.UL in a circle
2. Word “LISTED”
3. Product identifier
4. Control or issue number
