Glow-wire test

The glow-wire test is a type of flame-retardancy test used to evaluate the flammability and fire resistance of materials. It is a type of indirect flame test in which a red-hot heated wire is applied to the test specimen for evaluation. Based on the test results obtained through these methods, it is possible to compare and verify the ignition resistance of various materials, their self-extinguishing properties (in the event of ignition), and their non-propagation and non-spreading characteristics during dripping. The glow-wire test was established in 2001 by the International Electrotechnical Commission (IEC) because existing test methods did not cover certain ignition sources. Since then, the glow-wire test has been used to simulate thermal effects that may occur due to malfunction of electrical devices caused by overloaded connections or overheating of components.
