Glow-Wire Tester

Glow-Wire Tester

Parts of electric and electronic equipment may be exposed to overheating stress from internal faults or excessive current, degrading safety performance. Insulating materials and other combustible components inside devices risk ignition when in contact with a hot element or glow wire. The Glow-Wire Tester simulates these conditions to assess fire risk and combustion performance under standardized protocols.

• Plastic automotive interior flame retardant tester—verifies dashboards, trim panels, and seat components resist ignition.  

• Flame retardant test for consumer electronics—ensures housings and insulators comply with IEC and UL safety standards.  

• Fire resistance test of electrical appliances—evaluates risk of internal fire spread.  

• Horizontal and vertical needle flame combustion test chamber—measures flame propagation on wiring and small plastic parts.
