Fire hazard testing - Part 11-11: Test flames - Determination of the characteristic heat flux for ig...
IEC 60695-11-11:2021 describes a test method used to determine the characteristic heat flux for ignition (CHFI) from a non-contacting flame source for materials used in electrotechnical products, sub-assemblies or their parts. It provides a relationship between ignition time and incident heat flux. A test specimen cut from an end-product or sub-assembly can be tested by this test method.
