Fire resistance must be defined through the applicable test method and performance requirement. The names EPDM, neoprene, FKM and silicone describe material families; they do not establish a fire rating for every compound or finished part.
Separate heat and fire requirements
A compound's operating-temperature range concerns performance during service. Flame spread, burning behavior and smoke characteristics involve different tests. Passing one requirement does not prove compliance with another.
Request relevant evidence
Specify the required classification, part thickness, operating environment and any additional application requirements. Review the documentation for the proposed compound and confirm that it covers the intended configuration.
Do not select a generic grommet for a fire barrier, smoke seal or chimney application solely from a material description. Such applications require an appropriate component or system specification and supporting evidence. Confirm the exact role of the part before ordering.
