This European Standard specifies the steel grades of grain-oriented electrical sheet and strip in nominal thicknesses of 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm; in particular, general requirements, magnetic properties, geometric characteristics and tolerances and technological characteristics, as well as inspection procedures.
This European Standard applies to Goss textured grain-oriented magnetic sheet steel supplied in the final annealed condition in sheets or coils, and intended for the construction of magnetic circuits.
The materials are grouped into two classes :
a) conventional grain oriented material ;
b) high permeability grain oriented material .
They correspond to Clause C22 of IEC 60404-1:2000.
