IEC60065 Hot Wire Ignition Tester
It is suitable for electric and electronic products, household appliance materials to do ignition dangerous test. It simulates the heat source or ignition source of simulates glow component and overload resistance which may cause thermal stress in a short time.
Information technology equipment, low voltage switch and control equipment parts.
Hot-wire coil ignition test adopts the specific size (ф0.5mm length:250mm) and specific material (Ni80/Cr20) of heater strip which is pre-annealed with required heating power(0.26W/mm) and time (8s～12s). Then coil heater strip on the specimen for 5 cycles according to certain wire wrapping tension (5.4N) and certain wire wrapping distance (6.35mm). Next, take the specimen with wrapping heater strip to test until 120s under the stipulate heating power (0.26W/mm) the users can judge the fire risk according to whether the specimen ignite and the ignite time.
