IEC/TS 60695-11-11:2008 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 and sub-assemblies. 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. Has the status of a basic safety publication in accordance with IEC Guide 104.
