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.
This basic safety publication is intended for use by technical committees in the preparation of
standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
basic safety publications in the preparation of its publications. The requirements, test methods
or test conditions of this basic safety publication will not apply unless specifically referred to or
included in the relevant publications.
