That is correct only for UL where they do some type of verification to ensure the polymeric material has not changed. They figure it is hard to trust the fabricated part manufacturers. During the original evaluation, they do some sort of fingerprinting. Once a year they do a verification after their follow up inspector sends in a sample.

Hence, the benefit of using UL Recognized plastic materials and using them within their Recognition parameters.

These are done on small scale samples and the engineer in charge of the investigation of the end product determines suitability. If a polymeric material is not Recognized, the standard either refers you to another standard such as UL 746C in the US where you can apply tests on the overall enclosure material in lieu of small scale samples. So in response to your question, a polymeric material does not have to have UL/CUL. It can be tested as part of the end product evaluation.

All that I have reviewed also have a cUL. (Approval to CAN/CSA‑C22.2 No. 0.17) In dealing with a new supplier that is getting the approvals on their acrylic material, for use in a worldwide market, is it necessary to get the UL and the cUL?
