Specifies the glow-wire apparatus and common test procedure to simulate the effect of thermal stresses which may be produced by heat sources such as glowing elements or overleaded resistors, for short periods, in order to assess the fire hazard by a simulation technique. The test described in this standard is applicable to electrotechnical equipment, its subassemblies and components, and may also be applied to solid electrical insulating materials or other solid combustible materials. Has the status of a basic safety publication in accordance with IEC Guide 104.
