1 Scope
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.
