The glow wire test to IEC 60695-2, EN 60695-2, VDE 0471-2 The glow wire test to IEC 60695-2-11 is used to test electrical products, assemblies or individual components. The glow wire temperature is determined by the Electrical Equipment Committee as a function of the type of risk arising when the product is used. During the test, a note is made of the burning time te (s) after an application time of 30 s, and the dropping of burning or glowing particles of the specimen. The test is considered passed if a) the specimen does not constitute an ignition risk to the environment and b) any flames or glowing on the test specimen extinguish not later than 30 seconds after removal of the ignition source.

The glow wire test to IEC 60695-2-12 can also be used to test simple material specimens – e.g. discs. The test determines the glow wire flammability index (GWFI), this being the highest temperature at which flaming or glowing of the specimen extinguishes within 30 seconds of the removal of the glow wire coil, without burning or glowing particles dropping onto and igniting the material situated below the specimen. In another version of this test (the glow wire test to IEC 60695-2-13), the ignitability of different materials can be compared. The glow

wire ignitability temperature (GWIT) determined here is 25 K higher than the highest temperature (glow wire temperature) thatdoes not lead to ignition (flaming combustion time > 5 s) in three successive tests
