scope:

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,

and

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).

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

lEC 60695-2-12: 2010 Fire hazard testing-Part 2-12: Glowing/hot-wire based test methods-Glow-wire flammability index (GWFI) test method for materials (IDT)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
