en 60335-1  glow wire flammability/ignition index test apparatus

Introduction:

The glow wire test chamber conforms to IEC60695-2-10,UL 746A ,GB/T5169.10,GB4706.1, use no-flame ignition simulate the test.  Heating up the glow wire loop, which material and shape is (Ni80/Cr20) and(Φ4 mm nickel chrome)by large current to the testing temperature 550C ~ 960C for 1min, then to heat the sample with 1N force for 30sec. To judge the fire fatalness of the electrical and electronic equipment or product by to see whether the sample is ignited or how long is the burning time.  The tester can test the ignitability, flammability , GWFI and GWIT of solid insulated and combustible material.

The glow wire test chamber is widely used for testing the electrical and electronic product like lighting equipment, low-voltage apparatus and electrotechnical instrument.
