IEC 60455-3-8:20 21 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 60455-3-8:20 21给出了符合本规范并满足既定性能水平的电力电缆附件树脂的要求。然而，用户对特定应用的材料的选择将基于该应用中足够性能所必需的实际要求，而不仅仅是基于本说明书。这些材料设计用于低压和中压电缆附件，因此，电气性能作为组件的一部分得到了证明。在EN 50393和IEC 60502-4中描述了这方面的示例。这第二版取消并取代了2013年出版的第一版。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: -条款1:引入了与符合IEC 60502-4和EN 50393的组件的链接； -名称:重新定义了类别，特别是机械类别； -型式试验:根据材料的化学基础更新了试验； -型式试验:引入了额外的材料； -附件A:建立了考试网格。

IEC 60455-3-8:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 60455-3-8:2021 gives the requirements for resins for power cable accessories that conform to this specification and meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and not on this specification alone. These materials are designed to be used in low and medium voltage cable accessories and as such, electrical performance is proven as part of the assembly. Examples of this are described in EN 50393 and IEC 60502-4. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Clause 1: a link to assemblies according to IEC 60502-4 and EN 50393 was introduced;
- designation: the categories, especially the mechanical ones, were redefined;
- type tests: the testing was updated based on the chemical basis of the material;
- type tests: additional materials were introduced;
- Annex A: an examination grid was established.
