IEC 60695-2-13:20 21作为IEC 60695-2-13:20 21 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60695-2-13:20 21规定了适用于固体电绝缘材料或其他固体材料的试样进行可燃性测试的辉光线测试的细节，以确定辉光线点火温度(GWIT)。GWIT是比在该标准化程序中确定的最高测试温度高25 K（或30 K）的温度，在该温度下，测试材料不会点燃，或者对于任何单个火焰事件，持续燃烧不会发生超过5 s的时间，并且样品不会被完全消耗。本试验是在一系列标准试样上进行的材料试验。获得的数据以及来自材料辉光线可燃性指数(GWFI)测试方法IEC 60695-2-12的数据可用于根据IEC 60695-1-30[4]的预选过程中，以判断材料满足IEC 60695-2-11要求的能力。本基本安全性出版物侧重于安全性测试方法，主要供技术委员会根据IEC指南104和ISO/IEC指南51中规定的原则编写安全性出版物时使用。技术委员会的职责之一是在适用的情况下，在编制其出版物时利用基本安全出版物。本出版物应与IEC 60695-2-10一起阅读。本第三版取消并取代2010年出版的第二版和修正案1:2014.本版是技术性修订。与上一版相比，此版本包括以下重大技术变更:-第3条增加了关于时间和持续时间的新术语和定义，影响了试验方法的应用。

IEC 60695-2-13:2021 is available as IEC 60695-2-13:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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.
