This part of IEC 60404 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.<\/p>\n
Since these properties are functions of temperature, the measurements will be made at an ambient temperature of (23 \u00b15) \u00b0C except when specified in this document.<\/p>\n
