Further to Peter’s response and unless UL’s requirements have changed recently, parts made from non UL Recognized plastic materials or UL Recognized plastic materials used outside of their UL Recognition parameters and once approved for use in the end system UL Listing, will need to be annually resubmitted to UL for a re-evaluation. 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?
