UL is short for Underwriter Laboratories Inc UL Safety Laboratory is the most authoritative institution in the United States, and it is also a large private institution engaged in safety testing and appraisal in the world. It is an independent, non-profit professional organization that conducts experiments for public safety. Different from FCC certification, UL certification is a safety certification. UL is mainly engaged in product safety certification and operating safety certification business. Its ultimate goal is to obtain goods with a fairly safe level for the market and make contributions to ensuring personal health and property safety. In the United States, for consumers, UL is a symbol of safety signs, and globally, UL is one of the most reliable suppliers of conformity assessment for manufacturers.

UL 2056 standard is a safety standard for mobile power terminal products in the United States, which is suitable for products with DC power input and output of 60Vdc, but does not include products powered by external solar panels or vehicle-mounted 12Vdc power ports.

UL 2056 certification process for mobile power terminal products

1. Project determination: confirm the UL standard, certification cost and time, sample number, etc. on which the test is based;

2. Preparation of materials: According to the requirements of UL, the enterprise prepares various materials or documents required for certification;

3. Sample sending test: the enterprise sends samples to ZRLK testing laboratory for product testing;

4. Issue report: The product test results meet the requirements of UL standard, and the test report is formally issued;

5. Factory audit: UL will conduct the first factory inspection of the production factory to ensure that it meets the standard requirements;

6. Logo use: After the examination meets the requirements, the applicant is officially authorized to use the UL logo.
