电气绝缘用树脂基反应性化合物第3-8部分:单项材料规范电缆附件用树脂

[中文适用范围]： 本部分IEC 60455规定了符合本规范并达到既定性能水平的电力电缆附件用树脂的要求。然而，用户为特定应用选择材料将基于在该应用中实现充分性能的实际需求，而非仅基于本规范。这些材料设计用于低压和高压电缆附件，因此其电气性能作为组件的一部分得到证明。示例见EN 50393和IEC 60502-4。 [外文原描述]： 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.
