适用范围：This part of IEC 60404 defines the grades of cold-rolled grain-oriented electrical steel stripand sheet in nominal thicknesses of 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm. In particular,it gives general requirements, magnetic properties, geometric characteristics, tolerances andtechnological characteristics, as well as inspection procedures.This standard applies to Goss textured grain-oriented electrical steel strip and sheet suppliedin the final annealed condition in sheets or coils, and intended for the construction ofmagnetic circuits.The grades are grouped into two classes:- conventional grades;- high permeability grades.They correspond to Class C.22 of IEC 60404-1.
