Glow Wire Flammability Index Laboratory Test Principle:
The glow wire tester heats the heating wire (Φ4 mm nickel-chromium wire) of specified material (Ni80/Cr20) and shape to the test temperature (550℃～960℃ for 1min) with a large current, and then vertically burns the test sample with a specified pressure (1.0N) for 30s. The fire hazard of finished electrical and electronic equipment is determined by whether the test sample and the bedding ignite or the burning time; the ignition property, ignition temperature (GWIT), flammability and flammability index (GWFI) of solid insulating materials and other solid combustible materials are determined.
