BS EN IEC 60404-13:2018

What 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 factor to be determined. Since these properties are functions of temperature, the measurements will be made at an ambient temperature of (23 ±5) °C except when specified in .
