描述
Glow Wire Flammability Tester refers to GB/T5169.10; GB/T5169.11; GB/T5169.12; GB/T5169.13 (IEC60695-2-10; IEC60695-2-11; IEC60695-2-12; IEC60695-2 -13) “Glow wire / hot wire basic test method, 5169.10 glow wire test device and general test method; 5169.11 finished product glow ignitability test method; 5169.12 material glow wire flammability test method; 5169.13 material glow wire ignited Standard Test Methods and UL 746A, IEC829 VDE0471 and other standards stipulate the use of the flameless ignition source program simulation test project.
The glow wire tester will heat the test wire (Ni-C/Cr20) and the shape of the heating wire to the test temperature (550 °C ~ 960 °C) for 1 min, and then burn the test piece for 30 s at the specified pressure (1.0 N). And the ignition time of the matting material to determine the ignition hazard of the finished electrical and electronic equipment; determining the light-off property, light-off temperature (GWIT), flammability and flammability index of solid insulating materials and other solid combustible materials (GWFI).
Glow wire tester is applicable to GB4706.1, GB8898.1, GB4943.1, GB7000.1, GB4793.1 and other standards, such as lighting equipment, low-voltage electrical appliances, household appliances, machine tools, electric motors, electric tools, electronic instruments, electricians The research, production and quality inspection departments for electrical and electronic products and their components, such as instruments, information technology equipment, electrical equipment, electrical connectors and accessories, are also applicable to insulating materials, engineering plastics or other solid combustible materials industries.
