NBN EN 10107:2014

This European Standard defines the steel grades of grain-oriented electrical strip and sheet in nominal thicknesses of 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm and specifies 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 electrical strip and sheet 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 C.22 of IEC 60404-1:2000.
