UL certification tripartite organization: After receiving the application form, remittance and experimental samples signed by your company, the controller UL certification will notify you when the experimental plan is completed. The controller UL certification also accepts audited third-party test data. Experimental samples will be returned or destroyed upon your request. If the product test results meet the requirements of the controller UL certification standards, the controller UL certification will issue a test compliance report and follow-up service procedures (FollowUp Service Proccdure). The test report will detail the test, the indicators achieved by the sample, the product structure and the safety signs suitable for the use of the product. The product description and controller UL certification area inspector instructions are included in the tracking service specification. Send a copy of the test report to the applicant company and a copy of the tracking service details to each production plant.
UL certification tripartite organization: inspectors check the storage status of your products and their parts in the production line and warehouse to confirm that the product structure and parts are consistent with the tracking service rules. Area inspectors will also conduct witness experiments if required by the rules. When the test results meet the requirements, the applicant is authorized to use the controller UL certification mark.
UL certification tripartite organization: In short, mainly engaged in product safety certification and operating safety certification business, its goal is to obtain a relatively safe level of products for the market, to protect personal health and property safety to contribute. In terms of product safety certification as an effective means to eliminate technical barriers to international trade, controller UL certification also plays an active role in promoting the development of international trade.
