I work mainly in electrical safety standards and the term polycarbonate is not commonly used. Instead they simply say polymer, plastics, or something generic like that.
As for flammable materials, the standards I work with normally require 94 V-0 for anything in direct contact with high power or high voltage conductors. For indirect contact, they like to see 94 V-2. Materials, like insulating tapes and films, also have requirements like VTM-0, VTM-1, VTM-2, or foam insulation like HF-1, HF-2, HBF. So there is not a simple answer. And of course, the caveat is you MUST refer to the safety standard that is applicable to your product. -Doug Douglas E Powell Laporte, Colorado USA [email protected] LinkedIn <https://www.linkedin.com/in/coloradocomplianceguy/> (UTC -07:00) Mountain Time (US-MST) On Thu, Mar 2, 2023 at 8:05 PM MIKE SHERMAN <[email protected]> wrote: > Cecil -- > > Your inquiry is a bit broad, so it's hard to provide specific answers. > > If the polycarbonate parts are part of electrical equipment, you should be > able to find flammability requirements in the safety standards used for > that equipment in the intended markets. > > If the polycarbonate is for use in buildings and is permanent (e.g., > windows), I would expect that there might be some guidance in local > building codes. > > If the polycarbonate is used in furnishings (e.g., cashier shields), I > simply don't know.
