Underwriters Laboratories®
UL operates under its own authority as an independent, not-for-profit, nongovernmental organization.
To establish certification, samples of a product submitted by manufacturers for certification are tested and evaluated. If UL decides the product fulfills all applicable requirements it authorizes the manufacturer to apply a certification mark to production of the samples submitted, or issues a certificate or notification that the product is now certified by UL. A report of the evaluation is provided to the manufacturer. Before the manufacturer releases products with a certification mark, UL must initiate Follow-up Service in which periodic audits of products at the factory are completed by UL Field Representatives. These audits are described in a Follow-Up Service Procedure that is created as part of the initial evaluation of the product. For some products, factory samples are selected for retesting at UL. Certification continues until the manufacturer requests termination or fails to fulfill a requirement. UL must evaluate modifications to certified products before the modified product is authorized to bear the Mark or be considered certified.
Testing and evaluation of samples of products submitted for certification can be performed in UL's laboratories or in laboratories qualified by UL assessment and ongoing monitoring. Only UL reviews the results of all testing and evaluation and decides if the product is eligible for certification.
