Glow-wire tester

Theglow-wiretest is conducted by IEC6 0695-2-10～IEC6 0695-2-13 (GB/T5169.10-2006~GB/T5169.13-2006) "Glowing/hot-wire based test methods—Glow-wire apparatus and common test procedure" and UL 746A and IEC 829. DIN695, VDE0471 and other standards specify the use of flameless ignition source procedures simulation test items.

Glow-wire testing instrumentswill stipulate the material (diameter 4mm, Ni77/Cr20±1) and the shape of U-shaped heating wire with a high current heating to the test temperature (200℃~ 1250℃) 1min, after the prescribed pressure (1.0N) vertical scalding test specimens for 30s, depending on whether the test specimens and bedding ignition or holding time to determine the electrical and electronic equipment products. The flammability, glow-wire ignition temperature (GWIT), flammability and glow-wire flammability index (GWFI) of solid insulating materials and other solid combustible materials are determined.

Glow-wire testing instrumentis suitable for the research, production and quality inspection departments of electrical and electronic products and their component parts, such as lighting equipment, low-voltage electrical appliances, household appliances, machine tools, motors, power tools, electronic instruments, electrical instruments, information technology equipment, electrical services equipment, electrical connectors and accessories, etc. It is also suitable for insulating materials, engineering plastics or other solid combustible materials industry.
