Touch Screen Glow Wire Testing Machine
Scope of application:
Touch Screen Glow Wire Testing Machines test components or parts of a product that may reach excessive temperatures or ignite parts near them under faulty or overloaded conditions. Glow Wire Testing simulates glowing components or overloaded resistors like heat sources or ignition sources in a short period of time. The resulting thermal stress, the fire hazard is assessed using simulation techniques.
The touch screen glow wire testing machine is suitable for electrical and electronic products such as lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors and accessories, etc. The research, production and quality inspection departments of components are also suitable for the industries of insulating materials, engineering plastics or other solid combustible materials.
Purpose
The touch screen glow wire testing machine heats the heating wire of the specified material (Ni80/Cr20) and shape with a large current to the test temperature (550 ℃ ~ 960 ℃) for 1min, and then heats the test sample vertically with the specified pressure (1.0N) for 30s. Whether the test sample and bedding ignite or hold burning time to determine the fire hazard of finished electrical and electronic equipment; determine the ignitability, igniting temperature (GWIT), flammability and flammability index of solid insulating materials and other solid flammable materials (GWFI).
