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 :
- conventional grain oriented material
- high permeability grain oriented material .
They correspond to Clause C22 of IEC 60404-1:2000.
