Glow wire test apparatus for GWFI test of IEC60529

Glow wire test apparatus for GWFI test

 

Introduction:

1. The glow wire test is an IEC60695-2-10, UL 746A, GB / T5169.10, GB4706.1 and other standards that require the use of flameless ignition source program simulation test items.

2. The glow wire test chamber heats the specified material (Ni80 / Cr20) and shape of the heating wire (nickel chromium wire of Φ 4 mm) with a large current to the test temperature (550 ℃ ~ 960 ℃ for 1 minute, and then the specified pressure (1.0N) Vertically burn the test sample for 30s. Determine the fire hazard of the finished electrical and electronic equipment depending on whether the test sample and the bedding are on fire or hold time. ), Flammability and Flammability Index (GWFI).

3. Glow wire test chamber is suitable for research, production and quality inspection departments of lighting equipment, low-voltage electrical appliances, electrical instruments, and other electrical and electronic products and their components.
