Glow wire test

The glow-wire test is a type of flammability test used to evaluate the combustibility and fire resistance of materials. It is a method of indirect flame testing in which a heated wire is applied to the test object. The results of such tests using various methods make it possible to compare and examine the ignition resistance, self-extinguishing properties (in case of ignition), and the non-propagation and non-expansion characteristics during dripping. As for the origin of the glow-wire test, it was established in 2001 by the International Electrotechnical Commission (IEC), because existing test methods did not cover some ignition sources. Since then, the glow-wire test has been used to simulate thermal effects that may occur due to malfunctions in electrical devices caused by overload connections or overheating of components.
