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 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 glow-wire 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. The data obtained, along with data from the glow-wire ignition temperature (GWIT) test method for materials, IEC 60695‑2‑13, 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.
