IEC 60626-1:20 23作为IEC 60626-1:20 23 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 60626-1:20 23包含与电气绝缘组合柔性材料相关的定义和一般要求。本文件不包括IEC 60371系列涵盖的用作主要部件的云母纸，但基于云母纸的绝缘材料可用作组合式柔性材料的部件。符合本规范的材料符合既定的性能水平。然而，用户对特定应用的材料的选择是基于该应用中足够性能所必需的实际要求，而不是仅基于本说明书。第四版取消并取代了2009年出版的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a)本系列标准中可用的材料已更新； b)已经创建了一个框架，允许使用超出质量控制规范的测试方法，以允许出于鉴定目的进行测试。

IEC 60626-1:2023 is available as IEC 60626-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60626-1:2023 contains the definitions related to and the general requirements to be fulfilled by combined flexible materials for electrical insulation. This document does not include mica papers used as a primary component, which are covered by the IEC 60371 series, but insulation materials based on mica paper can be used as component of a combined flexible material. Materials which conform to this specification meet established levels of performance. However, the selection of material by a user for a specific application is based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. This fourth edition cancels and replaces the third edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the materials available for use within this series of standards have been updated;
b) a framework has been created to allow test methods beyond those used for quality control specifications to allow for testing for qualification purposes.
