BS EN IEC 60404-13:2018规定了测定电阻率、密度和电阻率的方法 晶粒取向和无取向电工钢带和薄板的堆叠系数。这些 数量是确定材料物理特性所必需的。此外 密度是允许指定的磁极化、电阻率和电阻值所必需的 堆积系数待定。交叉引用:IEC 60404-3IEC 60404-2IEC 60050-221IEC 60050-121EN ISO 1183-3ISO 1183-3EN 60404-2ISO 2738:1999EN ISO 1183-1:2012ISO 1183-1:2012EN ISO 2738:1999ASTM A34/A34M-06（2012）购买本文件时包括所有当前可用的修改件。

BS EN IEC 60404-13:2018 specifies the methods used for determining the resistivity, density and stacking factor of grain-oriented and non-oriented electrical steel strip and sheet. These quantities are necessary to establish the physical characteristics of the material. Moreover, the density is necessary to allow specified values of the magnetic polarization, resistivity and stacking factor to be determined.Cross References:IEC 60404-3IEC 60404-2IEC 60050-221IEC 60050-121EN ISO 1183-3ISO 1183-3EN 60404-2ISO 2738:1999EN ISO 1183-1:2012ISO 1183-1:2012EN ISO 2738:1999ASTM A34/A34M - 06(2012)All current amendments available at time of purchase are included with the purchase of this document.
