UL746A Electronic Safety Burn-in Test Glow Wire Tester
Introduction :
1,The tester comforms to IEC6069
5-2-10, UL 746A, GB/T5169.10, GB4706.1
2, The glow wire tester heat the stipulated material, Ni80/Cr20, and heating wire, nichrome wire with diameter of 4 mm with high current up to test temperature 550 ºC ~ 960 ºC. After 1 minute, it burn the specimen verticality for 30s with specified pressure 1.0N. The ignitability of electric and electronic equipments is tested by judging whether the specimen and bedding materials are ignited or deciding the length of burning time; also, the ignitability, ignition temperature(GWIT) , flammability and flammability index of the solid insulating material and some other solid combustible materials are tested in this way.
3,The glow wire tester is usually applied to the research, production and quality testing departments for electric and electronic products as well as their parts and components, such as lighting equipment, low-voltage apparatus, electric instrument.
