Glow Wire Test - IEC 60695-2-10
The glow wire test is used to simulate the effect of heat as may arise in malfunctioning electrical equipment, such as with overloaded or glowing components.
The glow wire is heated via electrical resistance to a specified elevated temperature. A test specimen is held for 30 seconds against the tip of the glow wire with a force of 1 N. After the glow wire is removed, the time for the flames to extinguish is noted along with details of any burning drops. Material that surrounds the test material in application or a layer of tissue paper is placed beneath the specimen during the test to determine the effects of burning drops.
The material passes the test if one of the following apply.
- There is no flame and no glowing.
- If flames or glowing of the specimen, or the surrounding material, extinguish within 30 seconds after removal of the glow wire.
