IEC 60950 Fire Hazard Glow-wire Flammability Testing Equipment
Standard:
IEC60695-2-10 Fire hazard testing – Part 2-10: Glowing/hot-wire based test methods – Glow-wire apparatus and common test procedure;
IEC60695-2-11 Fire hazard testing – Part 2-11 : Glowing/hot-wire based test methods – Glow-wire flammability test method for end-products;
IEC60695-2-12 Fire hazard testing – Part 2-12: Glowing/hot-wire based test methods – Glow-wire flammability index (GWFI) test method for materials;
IEC60695-2-13 Fire hazard testing – Part 2-13: Glowing/hot-wire based test methods – Glow-wire ignitability test method for materials.
Application:
The glow wire test apparatus simulates the thermal stress test of glowing component or heat source like overload resistance or ignition source which is caused in a short time. It is suitable for electric and electronic products, household appliances and other material to do fire hazard testing. It is also used in the no flame ignition source fire test to test initiation temperature and flammability index of related glowing filament. Flammability Testing Equipment
