火灾危险试验 - 第2-10部分：基于灼热丝/热丝的试验方法 - 灼热丝装置和通用试验程序

[中文适用范围]： 本标准适用于IEC 60695-2-10:2026《灼热丝测试方法》（第4.0版）的官方文本及其注释版。注释版提供便捷方式，以便对比该版本与2021年发布的第3.0版（IEC 60695-2-10:2021）之间的全部变更；同时收录国际电工委员会第89技术委员会（IEC TC 89）专家意见，用以阐释相关重大修改的原因，或对内容中某些部分予以澄清。 IEC 60695-2-10:2026规定了灼热丝试验装置及其通用试验程序，旨在模拟由发热源（如灼热元件或过载电阻器）在短时间内产生的热应力所引发的效应，从而通过模拟技术评估火灾危险性。本文件所述的试验程序为通用方法，适用于小规模试验，其中采用标准化的电加热丝作为点火源。该程序是应用于终端产品、固体电气绝缘材料或其他固体可燃材料的系列试验方法的组成部分之一。具体试验程序的详细描述见IEC 60695-2-11、IEC 60695-2-12及IEC 60695-2-13。 本第四版废止并取代于2021年发布的第三版，属技术性修订。与前一版本相比，本版包含以下主要技术变更：a) 修订第4.3节，增加对新附录D的引用；b) 新增规范性附录D“灼热丝试验中高温计的用法”；c) 修订第3章的参考文献，使其与ISO 13943:2017保持一致。 根据IEC指南104，本标准具有基础安全出版物地位。本国际标准应与IEC 60695-2-11、IEC 60695-2-12及IEC 60695-2-13联合使用。 [外文原描述]： IEC 60695-2-10:2026 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60695-2-10:2026 edition 4.0 and the previous IEC 60695-2-10:2021 edition 3.0. Furthermore, comments from IEC TC 89 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60695-2-10:2026 specifies the glow-wire apparatus and common test procedure to simulate the effects of thermal stresses which may be produced by heat sources such as glowing elements or overloaded resistors, for short periods, in order to assess the fire hazard by a simulation technique. The test procedure described in this document is a common test procedure intended for the small-scale tests in which a standardized electrically heated wire is used as a source of ignition. It is a common part of the test procedures applied to end products and to solid electrical insulating materials or other solid combustible materials. A detailed description of each particular test procedure is given in IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13. This fourth edition cancels and replaces the third edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision of 4.3 to add reference to new Annex D; b) addition of new normative Annex D on "Use of pyrometer for glow-wire test"; c) revision of Clause 3 references to align with ISO 13943:2017. It has the status of a basic safety publication in accordance with IEC Guide 104. This International Standard is to be used in conjunction with IEC 60695-2-11, IEC 60695-2-12, and IEC 60695-2-13.
