电气用硫化纤维第1部分:定义和一般要求

[中文适用范围]： 本部分 IEC 60667 给出了用于电气目的的硫化纤维板的定义和一般要求。通过粘合剂将多层硫化纤维结合而成的材料不在本文件范围内。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中足够性能的实际需求，而不仅仅是基于本规范。安全警告：本文件中所包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 60667-1:2020 gives the definitions and general 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 1980. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: deletion of "corrugated, round rods, and round tubes" from the Scope; types A, B and C replaced by general and fishpaper types and addition of a symbol for each type in the classification; addition of white, blue, brown, and addition of a symbol for each colour; deletion of the thickness of 15,0 mm, the length, the mass and the dimension of rolls from the general requirements; addition of the manufacturer's name, trademark (if any), nominal thickness, manufacture date, and lot number in the conditions of supply.
