This Standard specifies the details of the glow-wire test when applied to specimens of solid electrical insulating materials or other solid combustible materials for ignitability testing. The test results make it possible to provide a relative comparison of various materials according to the temperature at which the test specimen ignites during the application of the electrically heated glow-wire as ignition source. The test method is not valid for determining the ignition behaviour of complete items of equipment, since the dimensions of the insulating systems or combustible parts, the design and heat transfer to adjacent metallic or non-metallic parts, etc. greatly influence the ignitability of the materials used therein. In addition to this, it is not valid for determining fire behaviour and fire hazard of equipment.
