Glow Wire Apparatus
Glow Wire Test Apparatus is designed to test the resistance to fire of insulating
parts. It assesses the susceptibility of electrical insulating materials to ignition as a result
of exposure to a glowing wire.This test method determines the minimum temperature
required to ignite a material by the effect of a glowing heat source, under the specified
conditions of test.
