标准范围

IEC 60667-2:20 20给出了电气用硫化纤维板的测试方法。通过与粘合剂结合几种厚度的硫化纤维制成的材料不在本文件的范围内。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是基于该应用中足够性能所必需的实际要求，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1982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)增加了术语和定义b）增加了测试的一般注释c)增加厚度而不是尺寸d)表观密度从密度改变e)增加的电弧电阻f)删除的硫酸盐含量g）增加了灵活性的方法（弯曲）h）改变了内层粘合力的测试方法i)增加的收缩

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
