用于电气用途的硫化纤维 - 第2部分:测试方法

[中文适用范围]： 本部分IEC 60667规定了用于电气目的的石棉酚醛纤维板（硫化纤维板）的试验方法。将多层硫化纤维板结合粘合剂制成的材料不包括在本文件中。符合本规范的材料达到了既定的性能水平。然而，用户对特定应用的材料选择是基于该应用所需的实际要求，而不仅仅基于本规范。安全警告：用户有责任确保以安全的方式使用本文件中包含或参考的方法。 [外文原描述]： IEC 60667-2:2020 gives methods of test for vulcanized fibre sheets for electrical purposes. Material made by combining with an adhesive several thicknesses of vulcanized fibre is not covered by this document. 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 1982. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) added Terms and definitions b) added General notes on tests c) added Thickness instead of dimension d) changed Apparent density from Density e) added Arc resistance f) deleted Sulphate content g) added method (Bending) for flexibility h) changed test method for internal ply adhesion i) added Shrinkage
