IEC 60893-3-5:20 03+A1:2009给出了基于聚酯树脂和不同增强材料的电气用工业刚性层压板的要求。给出了应用和区别性质。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应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。在本次IEC 60893系列规范的修订中，纳入了新的材料类型，对部分现有类型的性能要求进行了更改，增加了新的介电常数和耗散因子测试方法，并将每种类型的所有非规范数据移至新的Part 4文件中-IEC 60893-4:典型值。 本合并版本由第二版（2003年）组成 及其修正案1（2009年）。因此，无须在 本出版物的补充。

IEC 60893-3-5:2003+A1:2009 Gives the requirements for industrial rigid laminated sheets for electrical purposes based on polyester resins and different reinforcements. Applications and distinguishing properties are given. 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. In this revision of the IEC 60893 series of specifications, new material types have been included, changes have been made to the property requirements of some existing types, a new method for testing permittivity and dissipation factor has been added, and all non-specification data for each type has been moved to a new Part 4 document - IEC 60893-4: Typical values. This consolidated version consists of the second edition (2003) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
