IEC 61462:2023适用于复合中空绝缘子，该复合中空绝缘子由树脂浸渍纤维制成的承重绝缘管、由弹性材料（例如硅树脂或乙烯-丙烯）制成的外壳（绝缘管外部）以及绝缘管末端的金属固定装置（示例见图D.1和图D.2）。本文件的目的是定义所使用的术语，指定测试方法；并规定验收标准。本文件区分了设计试验和型式试验，因为特定设计和特定材料组合的几个一般特性对于不同的绝缘子类型不会有所不同。这个新版本取消并取代了2007年出版的上一版。与上一版相比，此版本包括以下重大技术变更:a)术语和定义的修改； b)IEC TR 62039和IEC 62217中包含的测试程序的修改（疏水性转移测试；带外壳的芯的水扩散测试）； c)修改第8条（型式试验），以反映常见做法并考虑锥形（圆锥形）绝缘体； 通过将密封性测试设置为最后一个阶段来修改机械样品测试（9.4）的阶段顺序； d)表3（设计变更后进行的试验）与其他产品标准的协调； e)增加新的资料性附件D:空心绝缘子设计组件的原理图； f)增加新的信息性附件E:锥形（圆锥形）绝缘子的型式试验。

IEC 61462:2023 applies to composite hollow insulators consisting of a load-bearing insulating tube made of resin-impregnated fibres, a housing (outside the insulating tube) made of elastomeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube (see Figure D.1 and Figure D.2 for examples). The object of this document is to define the terms used, to specify test methods; and to specify acceptance criteria. This document distinguishes between design tests and type tests because several general characteristics of a specific design and specific combinations of materials do not vary for different insulator types. This new edition cancels and replaces the previous edition published in 2007. This edition includes the following significant technical changes with respect to the previous edition:
a) modifications of terms and definitions;
b) modifications of tests procedures included in IEC TR 62039 and IEC 62217 (Hydrophobicity transfer test; Water diffusion test on the core with housing);
c) modification of Clause 8 (type tests) to reflect common practice and to also consider tapered (conical) insulators;
modification of order of the stages of mechanical sample test (9.4) by setting the tightness test as last stage;
d) harmonization of Table 3 (Tests to be carried out after design changes) with other product standards;
e) addition of a new informative Annex D: Principle sketch of hollow insulators design assembly;
f) addition of a new informative Annex E: Type tests on tapered (conical) insulators.
