Magnetic materials - Methods of measurement of resistivity, density and stacking factor of electrical steel strip and sheetWhat is IEC 60404 13 Best measurement methods for magnetic materials about? IEC 60404 13 specifies the methods used for determining the resistivity, density and stacking factor of grain oriented and non oriented electrical steel strips and sheets. 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
