For chargers believe that everyone is not unfamiliar, in our life is also very common, such as mobile phones, computers, electric vehicles, etc., need to use chargers. However, as 3C products become more and more light and portable, the size of the charger becomes smaller and smaller, and the safety hazards emerge.

UL charger certification standard: 1, need to apply for UL certificate The applicant signs the application form and the tracking service agreement and places the form back to UL Company. At the same time, please send the sample at the post office or by Speedpost through bank remittance. Please give an appropriate description(such as name, model) of the charger sample sent for inspection. Please send samples of application form and charger separately. For each application item, UL will specify a unique project number(project number. ) to specify the project number and the name of the applicant company at the time of remittance, sample delivery and application for UL inspection. 2, need to test the product Upon receipt of your signed application form, remittance, sample of the experiment, UL will inform you of the date of completion of the project. The testing of charger products is generally conducted in the UL laboratory in the United States. UL can also accept audited third-party test data. The test samples will be sent back or destroyed according to your request. If the test results of the charger product meet the UL standard, the UL company will issue a test qualification report and a follow-up service detailed test report will detail the test situation, the indicators achieved by the sample, the product structure, and the safety Mark suitable for the use of the product. A description of the product and a guidance note for the UL regional inspector are included in the tracking service details. A copy of the inspection report is sent to the applicant company, and a copy of the follow-up service details is sent to each production plant. 3, the applicant is authorized to use the UL logo The UL regional inspectors in China contact the production plants for the first factory inspection. The inspectors inspect the product and its parts and components in the production line and warehouse storage. They have confirmed whether the product structure and parts are consistent with the tracking service rules if required in the rules. The District Inspector will also conduct a witness test, and the applicant will be authorized to use the UL sign when the inspection results meet the requirements. Following IPI, inspectors will visit the factory from time to time to inspect the product structure and conduct sighting experiments. The frequency of inspection is determined by the type of product and production volume. Most types of products are inspected at least four times a year. The inspector's inspection is to ensure that the product continues to comply with the UL requirements. Before you design changes to the product structure or components, please inform UL. For minor changes, no experiments need to be repeated. UL can quickly modify the tracking service details. Make this change acceptable to inspectors. When UL believes that changes in the product affect its safety performance, it needs to apply for new samples to be submitted for necessary testing. The charger UI certification standard is shared here. UL certification is essential to buy a safe and qualified product, so be sure to check if your charger is UL certified when you buy it.
