电气绝缘材料 耐热性 第1部分：老化程序和试验结果评价

[中文适用范围]： IEC 60216-1:2025 CMV包含官方标准及其注释版。注释版提供了一种快速简便的方式，用于比较IEC 60216-1:2025第7版与IEC 60216-1:2013第6版之间的所有变更。此外，IEC TC 112专家的注释也提供了对最重要变更原因的解释，或对内容部分进行澄清。IEC 60216-1:2025规定了用于推导热耐久特性的通用老化条件和程序，并提供指导，说明如何使用IEC 60216其他部分中的详细说明和指南。尽管该程序最初是为电气绝缘材料及其简单组合而开发的，但目前认为这些程序具有更广泛的应用范围，并广泛用于评估不用于电气绝缘的材料。在应用本文件时，假定在所需时间内引起预定性能变化的对数与相应绝对温度的倒数之间存在近似线性关系（阿伦尼乌斯关系）。为了本文件的有效应用，预计在研究的温度范围内不会发生任何过渡，特别是不会发生一级过渡。与上一版相比，本版包括以下重大技术变更：a）温度指数（TI）的定义已更新；b）增加了关于所用相关材料选择的要求，例如不同颜色（5.1.2）；c）增加了厚度敏感性测试程序（5.5和6.6）；d）删除了附录C“早期版本中的概念”。 [外文原描述]： IEC 60216-1:2025 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 60216-1:2025 edition 7.0 and the previous 60216-1:2013 edition 6.0. Furthermore, comments from IEC TC 112 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60216-1:2025 specifies the general ageing conditions and procedures to be used for deriving thermal endurance characteristics and gives guidance in using the detailed instructions and guidelines in the other parts of IEC 60216. Although originally developed for use with electrical insulating materials and simple combinations of such materials, the procedures are considered to be of more general applicability and are widely used in the assessment of materials not intended for use as electrical insulation. In the application of this document, it is assumed that a practically linear relationship exists between the logarithm of the time required to cause the predetermined property change and the reciprocal of the corresponding absolute temperature (Arrhenius relationship). For the valid application of this document, no transition, in particular no first-order transition, is expected to occur in the temperature range under study. This edition includes the following significant technical changes with respect to the previous edition: a) the definition for temperature index (TI) has been updated; b) requirements for selection of related materials used, e.g. in different colours (5.1.2), have been added; c) test procedure for thickness sensitivity (5.5 et 6.6) has been added; d) Annex C "Concepts in earlier editions" has been deleted.
