Home Products Combustibility Test Chamber > Glow Wire Tester
The hot wire tester heats a specified material (diameter 4mm, Ni77/Cr20 ± 1) and U-shaped electric wire with high current to the test temperature (200 ℃~1250 ℃) for 1 minute, and then burns the test sample vertically at the specified pressure (1.0N) for 30 seconds. The ignition hazard of the finished electrical and electronic equipment is determined based on whether the test sample and the substrate ignite or hold on for a certain period of time; Determine the ignition properties, ignition temperature (GWIT), flammability, and flammability index (GWFI) of solid insulation materials and other solid combustible materials.

DESCRIPTION
The hot wire tester isIEC6 0695-2-10~IEC6 0695-2-13 (GB/T5169.10~GB/T5169.13)The Burning Silk /Basic test methods for hot wire, hot wire test apparatus, and general test methods, etcUL 746ATheIEC829 DIN695TheVDE0471According to standard regulations, simulation test projects using flameless ignition source programs are required.
The hot wire tester will specify the material(diameter4mm,Ni77/Cr20±1) andUHeating the shaped electric heating wire with high current to the test temperature( 200℃ ~ 1250 ℃)1minAfterwards, to regulate the pressure(1.0N)Vertical burning test sample30sDetermine the fire hazard of electrical and electronic equipment products based on whether the test sample and bedding ignite or hold on for a certain period of time; Determination of ignition properties and ignition temperatures of solid insulation materials and other solid combustible materials (GWIT)Flammability and Flammability Index(GWFI).
The hot wire tester is suitable for research, production, and quality inspection departments of electrical and electronic products and their component parts such as lighting equipment, low-voltage appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors, and accessories. It is also suitable for industries such as insulation materials, engineering plastics, or other solid combustible materials.
