包含与电气用工业刚性层压板相关的定义以及其应满足的一般要求，该层压板使用以下任何一种树脂作为粘合剂:环氧树脂（环氧化物）、三聚氰胺、酚醛树脂、聚酰亚胺、硅酮和不饱和聚酯。以下钢筋可单独使用或组合使用:；纤维素纸、棉布、玻璃布、玻璃粗纱、玻璃垫、聚酯布和木贴面。 符合本规范的材料符合既定的性能水平。 然而，用户为特定应用选择材料时，应基于该应用中充分性能所需的实际要求，而不是仅基于本规范。 与上一版IEC 60893-1相比，主要变化如下: a） 新的材料类型被包括在内； b） 对一些现有类型的财产要求进行了更改； c） 增加了一种测试介电常数和损耗因子的新方法； d） 每种类型的所有非规范数据已移至IEC 60893的新第4部分。

Contains the definitions related to, and the general requirements to be fulfilled by, industrial rigid laminated sheets for electrical purposes, made with any of the following resins as the binder: epoxy (epoxide), melamine, phenolic, polyimide, silicone and unsaturated polyester. The following reinforcements may be used either singly or in combination; cellulosic paper, cotton cloth, glass cloth, glass roving, glass mat, polyester cloth and wood veneers. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. The major changes from the previous edition of IEC 60893-1 are the following: a) new material types have been included; b) changes have been made to the property requirements of some existing types; c) a new method for testing permittivity and dissipation factor has been added; d) all non-specification data for each type has been moved to a new Part 4 of IEC 60893.
