电气用硫化纤维第3部分:单项材料规范活页1:平板

[中文适用范围]： 本文档规定了用于电气目的的硫化纤维片的要求。通过胶粘剂将多层硫化纤维结合而成的材料不在此文件覆盖范围内。符合本规范的材料满足既定的性能水平。然而，用户为特定应用选择材料是基于该应用所需的实际要求，而不仅仅是基于本规范。安全警告：使用本文件中包含或引用的方法的用户有责任确保以安全方式使用这些方法。 [外文原描述]： IEC 60667-3-1: 2020 gives requirements for vulcanized fibre sheets for electrical purposes. Materials made by combining with an adhesive several thicknesses of vulcanized fibre are not covered by this document. Materials that 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 1986. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: change to the range of thickness deviation in Table 1; addition of apparent density in Table 1; change to the range of thickness for tensile strength in Table 1; addition of flexibility and shrinkage in Table 1; change test method and property value of internal ply adhesion on Table 1.
