RH-5014 Glow Wire Test Apparatus
Application
Insulating materials in electrical equipment need to resist ignition from thermal stresses induced by non-flaming glowing sources, for short periods. The performance of the internal materials cannot affect the fire safety of equipment. Glow Wire Test Apparatus using electricity heating regulation material (Ni80 / Cr20) of resistance wire (Φ 4 mm Ni-Cr alloy wire) to 550 ℃~ 960 ℃ in 1 min, then with 1.0 N vertically burn it 30s, measure the fire risk by product light-off or hold burning time, also test light-off degree, light-off temperature (GWIT; IEC 60695-2-13), flammability and combustible index (GWFI; IEC 60695-2-12). GWFI is the highest temperature which satisfies one of the following: (a) there is no flame and no glowing (no ignition) or (b) burning or glowing time is less than 30 s after removal of the glow wire and cotton under the specimen does not ignite; GWIT is a temperature 25°C higher than the maximum temperature of the glow wire tip which does not ignite the material. Glow Wire Test Apparatus suitable for lighting equipment, low voltage electric appliance and electrician instruments such as electrical and electronic products.
