Certificate Services Program

This is another service available under UL's Performance Verification Program for LAN products/systems. Upon request, UL will conduct a third-party assessment to verify a subscriber's compliance with their proprietary performance specification for testing LAN products, and/or the design and testing of LAN systems/solutions. The assessment includes initial correlation testing between the subscriber's facility and UL, an engineering and management systems audit (modeled after ISO9002/ISO Guide25) of the subscriber's facility to determine compliance with their performance specification, periodic correlation testing at UL, and an annual surveillance audit to verify the subscriber's continued compliance with their specification. A Certificate of Compliance is issued to the subscriber upon acceptable completion of the assessment. Continued participation in this service is contingent upon acceptable completion of periodic correlation testing and the surveillance audit.
