Bibliography
IEC 60404-8-7:2017 is available as IEC 60404-8-7:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60404-8-7:2017 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 document applies to Goss textured grain-oriented electrical steel strip and sheet supplied in the final annealed condition in coils or sheets, and intended for the construction of magnetic circuits.
The grades are grouped into two classes:
– conventional grades;
– high permeability grades, including grades which may be delivered in the domain refined condition. They correspond to Class C22 of IEC 60404-1.
This fourth edition cancels and replaces the third edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– extension of the range of electrical steels to include the improved grades.
