火灾危险试验 第2-13部分 基于灼热/热线的试验方法 -材料的辉光丝点火温度（GWIT）试验方法

[中文适用范围]： 本部分IEC 60695规范了应用于固体电气绝缘材料或其他固体材料样品以进行可燃性测试，以确定灼热丝点火温度（GWIT）的灼热丝测试细节。GWIT是在此标准化过程中确定的最高测试温度以上25K（或30K）的温度，在该温度下，测试材料不会点燃，或者持续性火焰燃烧在任何单次火焰事件中持续时间不超过5秒，且试样未被完全消耗。该测试是在一系列标准试样上进行的材料测试。获得的这些数据，加上来自IEC 60695-2-12的灼热丝易燃性指数（GWFI）测试方法的数据，可用于根据IEC 60695-1-30进行预选过程，以判断材料满足IEC 60695-2-11要求的程度。 [外文原描述]： IEC 60695-2-13:2021 specifies the details of the glow-wire test to be applied to test specimens of solid electrical insulating materials or other solid materials for ignitability testing to determine the glow-wire ignition temperature (GWIT). The GWIT is the temperature which is 25 K (or 30 K) higher than the maximum test temperature, determined during this standardized procedure, at which the tested material does not ignite, or sustained flaming combustion does not occur for a time longer than 5 s for any single flame event and the specimen is not totally consumed. This test is a materials test carried out on a series of standard test specimens. The data obtained, along with data from the glow-wire flammability index (GWFI) test method for materials, IEC 60695-2-12, can then be used in a preselection process in accordance with IEC 60695-1-30 [4] to judge the ability of materials to meet the requirements of IEC 60695-2-11. This basic safety publication focusing on safety test method(s) is primarily intended for use by technical committees in the preparation of safety publications 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. This publication is to be read in conjunction with IEC 60695-2-10. This third edition cancels and replaces the second edition published in 2010 and Amendment 1:2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - New terms and definitions with regards to times and durations have been added to Clause 3, with an effect on the application of the test method.
