Products feature:
Products feature: Adopting solenoid valve switch to control the burning depth of test sample and equipped with measuring gauge, this device has the features of exact and rapid. The test sample will break away automatically from glowing filament after reaching the set time. Adopting the original imported UK LAB K type armour(0.5) whose temperature resistance is up to 1100°(exceed 1050°of standard requirement) , this device is with accuracy temperature control.
Introduction:
1. The glow wire test chamber is an IEC60695-2-10, UL 746A, 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.
Glow Wire tester is designed to carry out fire hazard testing on electro trchnical products.A digital temperature indicator is fitted which ,in conjunction with the thermocouple supplied ,accurately measures the glow wire temperature .The electrical circuit of the unit is fully protected by fusesand a miniaturesircuit breaker and incorporates mains on switching and push button control of output current.
