IEC 60695-2-13: glow wire ignition temperature test method for materials

IEC 60695-2-13 is a test method for the insulating material to be used in end products. This test method finds the Glow Wire Ignition Temperature (GWIT) for materials. The GWIT is the temperature 25K higher than the maximum temperature at which three test samples do not ignite, or any flame event which occurs only lasts for 5 seconds. This is slightly different to the GWFI, as samples can pass this test even if ignition occurs or lasts longer than 5 seconds.

The requirements for samples are similar to those laid out in IEC 60695-2-12, and the test is again conducted as in IEC 60695-2-11. A table of test temperatures is given in the standard.

The GWIT is expressed as temperature/sample thickness, e.g.: 850/3.0. If no ignition takes place at the last temperature in the table (960°), then the GWIT is expressed as >960/thickness, e.g.: >960/3.0.
