Glow wire test

The glow wire test is a type of flame-retardant test used to evaluate the flammability and fire resistance of materials. It is a form of indirect flame method that involves applying a red-hot wire to the test subject. The test results obtained using such methods allow for the comparison and evaluation of ignition resistance, self-extinguishing properties (in case of ignition), and non-flammability/non-propagation in the event of dripping. As for when the glow wire test originated, it was established in 2001 by the International Electrotechnical Commission (IEC), as existing test methods did not cover some ignition sources. Since then, the glow wire test has been used to simulate heat generation effects that may occur due to malfunctions of electrical devices caused by overloaded connections or component overheating.
