Glow Wire Tester, IEC60695-2-10 Flammability Testing Equipment ,Glow-wire apparatus
Introduction Test the ignition performance,ignition temperature (GWIT),solid
insulating material and other solid combustible
material,combustibility and flammability index(GWFI) .
Technical Parameter
Test procedure Installation * This tester should be placed on a level table * table size no less than 1400W * 900D * (600-800)H mm * Distance to the wall: > 200mm * Exhaust pipe: diameter of 100mm * The test room should be independent room equipped with exhaust system and firefighting device
1.1) install the exhaust pipe, tighten the fitting 1.2) checks the power supply wiring, ensures it’s correct and grounded 1.3) connect thermocouple as below: 1.4) connect wire control box as below
Debugging Before debugging, please check:
2.1) turn power switch on, the sample carrier come to the left end, left proximity switch light up 2.2) adjust current to minimum, press heating button, and run, sample carrier come to right end, and come back 30s later. 2.3) test sample fixing. Fix the sample tight inside fixture, ensure 7mm spacing in the tolerance. And close the viewing window.
Test Left: sample carrier small car go left Right: sample carrier small car go right Exhaust: exhausting Light: lighting Heating: Adjust the current, reach to required temperature. Wait 5min to let the temperature be steady. Start: Sample carrier automatically moves forward, timers (glow time, Ti, Te) start working, carrier returns when set glow time (30s) reached. Glow time: 30s Ti: the duration from the beginning of tip application up to the time at which the test specimen or the wrapping tissue placed below it ignites; Te: the duration from the beginning of tip application up to the time when flames extinguish during or after the period of application. Control box: when the sample start burning, press the button on control box, get ignite time Ti; when flame dies, presses the button on control box, get flame extinguish time Te. When test finished, do not open the viewing window until exhaust for at least 2min.
