IEC 60695 Glow Wire Test Apparatus Initiation Temperature And Flammability Index Testing
Product information:
This device is manufactured according to the standard of IEC60695-2-10, IEC 60695-2-11, IEC 60695-2-12, IEC60695-2-13, it is required by IEC 60335 clause 30, IEC 60598, UL746A, etc. This device simulates the thermal stress test of glowing component or heat source like overload resistance or ignition source which is caused in s 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.
This instrument adopts a new design concept and uses an advanced digital stepping motor to achieve precise positioning, and at the same time, realize rapid adjustment after specimen replacement, which truly meets the requirements of simple and convenient operation. The control system adopts PLC control, each parameter can reflect the real situation of relevant parameters, which is more real-time and accurately, and the operation is intuitive and convenient, meeting the needs of scientific research, far exceeding similar products.
Test principle:
The glowing filament whose material and shape is required(Ni80/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 (1.0N) 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.
