SCR Electroniks Glow Wire Test Apparatus – GWT A2

GLOW WIRE TESTER (also known as Glow Wire Test Apparatus) is designed to carry out fire hazard testing as specified in IEC 60695-2-10 2000-10. Flammability test is to check the ‘Resistance to Fire’ of electrical insulators that touch directly conducting parts & also parts of insulators. This test is also referred in many other standards such as IS 11000, IS 3854 : 1997 / IS 1293 :1988 / IS 371 :1999 & IS 11000 Pt 2 Sec 1, IEC 60335, IEC 884/94, IEC 60598, IEC 61058, BS 6458, BS EN 60695–2-10,11,12, etc.


Temperature Sensor – Thermocouple: Fine wire of Cr/Al of 0.5 mm diameter located in 0.6 mm diameter pocket hole in temperature sheath resistant to 1000 degree centigrade

In the model GWT A2, current is held approximately constant (15 % swing) once the heating element touches the specimen.

Heating Element – Glow Wire: Nickel / Chromium (>77% Ni/20±1%Cr) based heating element (glow wire) with overall diameter of 4.00mm ±0.07mm

Time Controller – Micro-controller based programmable timer 0 to 999 sec

The total test time can be programmed through keyboard

The ignition time and extinguish time of flame can be registered in timer

The stored time values can be viewed after the end of test

Setting on PC for PC based variant

Penetration Depth – Mechanically restricted to 7 mm

Specimen size – 180 x 150 max. & 15 x 15 Sq. mm min., Thickness 10mm to 80 mm.
