IEC60695-2-10 Flammability Testing Equipment Glowing/Hot-Wire Tester With Touch Screen Operation
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:
This device 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.
Test principle:
the glowing filament whose material and shape is required(Ni77/Cr20) is heated to the testing temperature of 550 ℃ - 960 ℃ for 1 min by using the glow wire tester with large current. Then using required pressure (0.95N) vertically burns the test sample for 30s. By observing whether the test sample and bedding object ignite or the burning time, the users can judge the ignition danger of electric and electronic products. It is used for the ignition test, ignition temperature (GWIT) test, flammability test and flammability index (GWFI) test of solid insulating material and other solid combustible material.
