Ul is the abbreviation for Underwriters Laboratories Inc. in the United States. The UL Safety Testing Institute is the most authoritative organization in the United States and also one of the largest civilian organizations in the world engaged in safety testing and certification. It is an independent, for-profit professional organization that conducts experiments for public safety. UL has a long history and can provide safety certification for all types of products.

There are four laboratories in the United States, and currently, inspection and commissioning agencies have been established in nearly 300 cities in 70 countries and regions overseas, with inspectors stationed in more than 130 cities in the United States. The product identification work for each laboratory is completed by the following 6 departments:

1. Anti theft and signal department;

2. Department of Disaster and Chemical Hazards;

3. Electrical Engineering Department;

4. Ministry of Fire Protection;

5. Heating, Air Conditioning and Refrigeration Department;

6. Water Supplies Department;

7. The types of UL's product certification experimental services can be divided into listing, accreditation, and grading. The listing is applicable to complete products and devices for various components that are replaced or installed by qualified personnel on site. Products recognized for identification can only be used as components on listed or graded products. Grading only evaluates specific hazards of the product or evaluates products that comply with standards other than UL standards.

The UL certification series includes a complete set of standards and a product engineering certification program that can determine whether all products meet the standard requirements. The factory tracking inspection program confirms that the approval mark is added to all products that meet the standard requirements.
