Abstract
Specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition temperature (GWIT).
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 used as an 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.
Has the status of a basic safety publication in accordance with IEC Guide 104.
