IEC 60695-2-12:2021 PDF Download

IEC 60695-2-12:2021 is a standard that specifies the glow-wire test method used to evaluate the flammability of solid electrical insulating materials and other solid materials. The purpose of this test is to determine the glow-wire flammability index (GWFI), which is the highest temperature at which the tested material does not ignite or, if it does, extinguishes within 30 seconds after the removal of the glow-wire and is not completely consumed. Additionally, any molten drips from the material should not ignite the wrapping tissue.

This test method is conducted on standard test specimens, and the results obtained, along with data from the glow-wire ignition temperature (GWIT) test method described in IEC 60695-2-13, can be used in the preselection process to assess the ability of materials to meet the requirements of IEC 60695-2-11.

The standard is primarily intended for use by technical committees in the development of safety publications. It should be read in conjunction with IEC 60695-2-10 and replaces the previous edition published in 2010. In this third edition, new terms and definitions related to times and durations have been added, affecting the application of the test method.
