適用范圍：This part of IEC 60695 specifies the details of the glow-wire test to be applied to testspecimens of solid electrical insulating materials or other solid materials for flammability testingto determine the glow-wire flammability index (GWFI).GWFI is the highest temperature, determined during this standardized procedure, at which thetested materiala) does not ignite or, if it does, extinguishes within 30 s after removal of the glow-wire and isnot totally consumed,andb) 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. Thedata obtained, along with data from the glow-wire ignition temperature (GWIT) test method formaterials, IEC 60695-2-13, can then be used in a preselection process in accordance withIEC 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 flammabilityand ignition tests may allow a reduction of end product testing.This basic safety publication is intended for use by technical committees in the preparation ofstandards 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 ofbasic safety publications in the preparation of its publications. The requirements, test methodsor test conditions of this basic safety publication will not apply unless specifically referred to orincluded in the relevant publications.
