电气用塑料薄膜第3部分:单项材料规范活页1:电容器用双轴取向聚丙烯（PP）薄膜

[中文适用范围]： 本IEC 60674-3表给出了双轴取向聚丙烯薄膜的要求，该薄膜具有光滑或粗糙的表面，在需要真空金属化时进行电晕处理。这些薄膜用作电容器中的电介质。符合本规范的材料达到既定的性能水平。然而，用户为特定应用选择材料应基于该应用中充分性能所需实际要求，而不是仅基于本规范。安全警告：本文件所含或引用的方法的使用者有责任确保以安全的方式使用它们。 [外文原描述]： IEC 60674-3-1:2021 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 60674-3-1:2021 gives the requirements for biaxially oriented polypropylene film having a smooth or rough surface, corona treated when required for vacuum metallization. The films are for use as dielectric in capacitors. Materials which conform to this specification meet established levels of performance. However, the selection of a 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. 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 1998 and Amendment 1:2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - this document has been completely revised editorially and technically and included in the IEC 60674 series of standards; - the test methods have been updated to reflect today’s state of the art.
