着火危险试验.第2-13部分:基于灼热/发热丝的试验方法.材料的灼热丝着火点(GWIT)试验方法

[中文适用范围]： IEC 60695 的这一部分规定了灼热丝测试的详细信息，该灼热丝测试适用于固体电绝缘材料或其他固体材料的测试样本，用于可燃性测试以确定灼热丝点燃温度 (GWIT)。 GWIT 是比最大测试温度高 25 K（或 30 K）的温度，在此标准化程序中确定，在该温度下，测试材料 a) 不会点燃，或 b) 如果不发生持续和连续的有焰燃烧对于任何单次火焰事件，持续时间超过 5 秒，并且样品不会完全燃烧。该测试是对一系列标准测试样本进行的材料测试。获得的数据以及来自材料灼热丝可燃性指数 (GWFI) 测试方法 IEC 60695-2-12 的数据可用于根据 IEC 60695-1-30 进行预选过程，以判断其能力材料满足 IEC 60695-2-11 的要求。本基本安全出版物旨在供技术委员会根据 IEC 指南 104 和 ISO/IEC 指南 51 中规定的原则制定标准。技术委员会的职责之一是，在适用的情况下，使用其出版物的编写过程中涉及基本安全出版物。除非相关出版物中特别提及或包含，否则本基本安全出版物的要求、测试方法或测试条件将不适用。 [外文原描述]： IEC 60695-2-13:2010 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 if sustained and continuous 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 second edition of IEC 60695-2-13 cancels and replaces the first edition published in 2000. It also constitutes a technical revision. The main changes with respect to the previous edition are: - modified title; - addition of an Introduction; - clarification of Scope; - expansion of Clause 2: Normative references; - expansion of Clause 3; - revision of Clause 4 to alignment with the IEC 60695-11 series to introduce guidance on test programs for material variations; - clarification of Clause 8: Conditioning (now Clause 7); - deletion of Clause 9: Initial measurement; - expansion of Clause 10: Test procedures (now Clause 8); - expansion of Clause 11: Observation and measurement (now Clause 9); - clarification of Clause 12: Evaluation of test results (now Clause 10); - expansion of Clause 13: Test report (now Clause 11). This publication is to be read in conjunction with IEC 60695-2-10:2000 . The contents of the corrigendum of February 2012 have been included in this copy.
