This Standard specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for flammability testing to determine the glow-wire flammability index (GWFI).
GWFI is the highest temperature, determined during this standardized procedure, at which the tested material
a) does not ignite or, if it does, extinguishes within 30 s after removal of the glowwire and is not totally consumed,
b) molten drips, if they occur, do not ignite the wrapping tissue.
This test method is a materials test carried out on a series of standard test specimens (see clause 4). The data obtained, along with data from the glow-wire ignition temperature (GWIT) test method for materials, JIS C 60695-2-13, can then be used in a preselection process in accordance with JIS C 60695-1-30 to judge the ability of materials to meet the requirements of JIS C 60695-2-11.
NOTE 1 As an outcome of conducting a fire hazard assessment, an appropriate series of preselection flammability (JIS C 60695-2-12) and ignition tests (JIS C 60695-2-13) may allow a reduction of end product testing (JIS C 60695-2-11).
