Magnetic materials – Part 8-7: Specifications for individual materials – Cold-rolled grain-oriented electrical steel strip and sheet delivered in the fully-processed state - Edition 3.0
 N 60404-8-7

Annotation

This part of IEC 60404 defines the grades of cold-rolled grain-oriented electrical steel strip and 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 and technological characteristics, as well as inspection procedures.

This standard applies to Goss textured grain-oriented electrical steel strip and sheet supplied in the final annealed condition in sheets or coils, and intended for the construction of magnetic circuits.

The grades are grouped into two classes:

- conventional grades;

- high permeability grades.

They correspond to Class C.22 of IEC 60404-1.
