For electrotechnical products, IEC 60695 indicates that the risk of fire is present in any electrical circuit which is energized. With regard to this risk, the objective of component circuit and equipment design, and of the choice of material, is to reduce the likelihood of fire, even in the event of foreseeable abnormal use, malfunction or failure. The practical aim is to prevent ignition due to the electrically energized part but, if ignition and fire occur, to control the fire, preferably within the bounds of the enclosure of the electrotechnical product.
The best method for testing electro technical products with regard to fire hazard is to duplicate exactly the conditions occurring in practice.The best instument for Glow Wire Test is glow wire testing instrument In most instances, this is not possible. Accordingly, for practical reasons, the testing of l products with regard to fire hazard is best conducted by simulating as closely as possible the actual effects occurring in practice.
Parts of insulating material or other material which are liable to propagate flames inside the equipment may be ignited by glowing wires or glowing elements. Under certain conditions(for example, a fault current flowing through a wire, overloading of components, and bad connections), certain elements may attain a temperature such that they will ignite parts in their vicinity.
The test is conducted by first heating the glow-wire to the required temperature. Either the specimen is then brought into contact with the tip, or the tip is moved into contact with the specimen.
