This standard specifies the glow wire test method for the ignitability test of samples of solid electrical insulating materials and other solid combustible materials. This test uses an electrically heated glow wire as the ignition source. The test results can be used to compare the light-off temperatures of the various materials mentioned above. This test method is not suitable for determining the ignitability of complete equipment, because the size and structure of the insulation system or combustible parts, and the heat transfer of adjacent metallic or non-metallic parts have a great influence on the ignitability of the materials used. . In addition, this test method is not intended for use in determining the fire performance or fire hazard of equipment.
