BS EN 60695-2-13:2010+A1:2014 Fire hazard testing - Glowing/hot-wire based test methods. Glow-wire ignition temperature (GWIT) test method for materials
1 Scope
This part of IEC 60695 specifies the details of the glow-wire test to be applied to test specimens of solid
electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition temperature (GWIT).
The GWIT is the temperature which is 25 K (or 30 K) higher than the maximum test temperature,
determined during this standardized procedure, at which the tested material
a) does not ignite, or
b) sustained flaming combustion does not occur for a time longer than 5 s for any single flame event and the specimen
is not totally consumed.
This test is a materials test carried out on a series of standard test specimens.
The data obtained, along with data from the glow-wire flammability index (GWFI) test method for materials, IEC 60695‑2‑12, can then be used in a preselection process in accordance with IEC 60695‑1‑30 to judge the ability of materials to meet the requirements of IEC 60695‑2‑11.
NOTE As an outcome of conducting a fire hazard assessment, an appropriate series of preselection flammability and ignition tests may allow a reduction of end product testing.
