This standard is an important test method specification for evaluating the fire hazard of finished electrical and electronic products. It employs a specific method known as the "Glow-Wire Flammability Test (GWEPT)," which involves heating a glow wire of specified material and shape to a set temperature and then applying it vertically to the finished product sample under standard pressure and duration. The test aims to simulate the thermal stress that finished products may endure under fault or overload conditions. By observing phenomena such as ignition of the sample and underlying materials, as well as the duration of combustion, it scientifically assesses the fire hazard of the final product. Conducting this test requires the use of specialized glow-wire test apparatus, which typically includes a glow-wire tip capable of precise heating to specific temperatures (e.g., 500°C to 1000°C), a device for applying constant pressure, an automatic timing system, and a module for recording combustion duration.
