  1, Class (Classified). UL's grading service is a safety certification procedure for evaluating the hazards and other special performance of products used in commercial or industrial environments in accordance with relevant laws and regulations. The grading service is mainly for building materials, various fire protection equipment and marine equipment.

  2, name (Listed). It is only used for complete products and various devices or devices that are replaced or installed by qualified personnel on-site. Products that belong to the UL listed service include: IT equipment, AV equipment, refrigerators, vacuum cleaners and other electrical equipment.

  3. Recognized. Recognition is mainly a safety certification for components and materials. The components approved by the accreditation service will be assembled in the finished product, and the components must meet the relevant license conditions before they can be applied to the corresponding finished product.
