IEC 60674-3-3:20 23给出了用于电绝缘的聚碳酸酯薄膜的要求。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可以基于该应用中足够性能所需的实际要求，而不是仅基于本说明书。安全警告:本文件中包含或提及的方法的用户有责任确保以安全的方式使用它们。这第二版取消并取代了1992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: a)标准标题已更改，以统一IEC 60674系列内的名称； b)更新规范性参考文献。

IEC 60674-3-3: 2023 gives the requirements for polycarbonate films used for electrical insulation. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application can be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. Safety warning: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. This second edition cancels and replaces the first edition published in 1992. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the title of the standard has been changed to unify the name within the IEC 60674 series;
b) update of the normative references.
