Abstract
Electrical steel is a soft magnetic material used in the manufacture of various electrical equipment intended for the transmission and conversion of electricity and used mainly in alternating magnetic fields of industrial frequencies. The key properties of such a material are AC magnetic properties, which are standardized when assessing the compliance of the material with the requirements of both Russian and foreign standards. The article presents information about the aspects of the development of reference materials for AC magnetic properties of electrical cold-rolled non-oriented steel made in the form of strips for the Epstein frame. The main feature of these reference materials is that the value of one of the two certified characteristics (specific power of magnetic losses) is transmitted directly from the State primary standard, and the other (magnetic induction amplitude) is determined in accordance with a certified measurement procedure. Their use will provide the possibility of a comprehensive and reliable determination of the magnetic characteristics of samples of non-oriented electrical steel normalized in accordance with the requirements of current standards.
