Glow wire tester would stipulate material (Ni80 / Cr20) and the shape of the heating wire (Φ nichrome wire 4 mm) in large current heated to test temperature (550 ℃ ~ 960 ℃), after 1 min to specified pressure (1.0 N) vertical burning hot try 30 s, inspect goods and bedding content whether light-off or the burning time is measured in electrical and electronic equipment products of fire risk; The ignitability, ignitability temperature (GWIT), flammability and flammability index (GWFI) of solid insulation materials and other solid combustible materials were determined. Glow-wire tester is suitable for the research, production and quality inspection of lighting equipment, low-voltage electrical appliances, electrical instruments, electrical and electronic products and their components.
