绝缘材料.电气用热固性树脂工业硬质层压板.第4部分:典型值

[中文适用范围]： IEC 60893 的这一部分作为技术报告，提供了未研究且未在 IEC 60893-3-2:2003/AMD1:2011@ IEC 60893-3-3:2003 表 5 中给出的特性典型值表格/AMD1:2011@ IEC 60893-3-4:2003/AMD1:2012@ IEC 60893-3-5:2003/AMD1:2009@ IEC 60893-3-6:2003/AMD1:2009@ IEC 60893-3-7 ：2003/AMD1：2009。这些典型值的目的是提供一般指导，不应被视为规范要求。下表给出了 IEC 60893 第 3 部分中描述的不同类型的电气用工业层压板的典型值。 [外文原描述]： IEC/TR 60893-4:2014(E) serves as a technical report and presents tables of typical values for properties that are not studied and not given in Table 5 of IEC 60893-3-2:2003/AMD1:2011, IEC 60893-3-3:2003/AMD1:2011, IEC 60893-3-4:2003/AMD1:2012, IEC 60893-3-5:2003/AMD1:2009, IEC 60893-3-6:2003/AMD1:2009, IEC 60893-3-7:2003/AMD1:2009. The purpose of these typical values is to give general guidance and should not be considered as specification requirements. The tables give typical values for the different types of industrial laminated sheets for electrical purposes described in the Part 3 sheets of IEC 60893. This second edition cancels and replaces the first edition, published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the typical values of modulus of elasticity in flexure and of comparative tracking index of EPGC (Epoxy Glass Cloth) types have been changed; - the typical values of new material types introduced in IEC 60893-3-2:2003/AMD1:2011 have been included.
