DIN EN 60695-2-13:2011-10

This part of the IEC 60695 series 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) if sustained and continuous 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 material preselection process in accordance with IEC 60695-1-30 to judge the ability of materials to meet the requirements of IEC 60695-2-11. The responsible Committee is K 133 "Prüfverfahren zur Beurteilung der Brandgefahr von elektrotechnischen Produkten und Isolierstoffen" ("Test methods for assessing the fire hazard of electrotechnical products and insulating materials") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
