The take a look at is performed to find out the ignition hazard of electrical and electronic tools, along with the flammability, glow-wire ignition temperature (GWIT), and glow-wire flammability index (GWFI) of reliable insulating materials along with other strong combustible components by heating the heater wire of specified substance and condition on the take a look at temperature with significant latest for your specified period of time, then scalding the check specimen vertically with specified stress for a certain period of time, and observing whether or not the specimen as well as bedding item ignites or the burning time.
The sample must be fixed to a carriage on which, by way of Glow Wire tester a stress twine, a fat that has a drive of 1N is effective within the path in the wire loop. Scales permit the looking through on the flame peak plus the depth of penetration. Approx 200 mm below the wire loop a board of pine wood, protected which has a layer of tissue paper, is mounted.
