Product information:
This tester conforms to the standard requirement of IEC60695-2-20. 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.
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.

Hot Wire Ignition Test is a type of resistance test to fire for materials of enclosures and decorative parts. The sample is put on a specified stand and an element wire is winded around the material to be tested
Technical specification
The test sample is sourced by DC power
Element Wire 80% Nickel and 20% Chromium – 3 bobbins included
Power consumption 0.26 W/mm – means a current of 7 A to passes through the element wire
Digital Ammeter and Voltmeter
Terminal to connect the element wire
