Scope

This part of IEC 60404 defines the grades of cold-rolled non-oriented electrical steel strip and sheet in nominal thicknesses of 0,35 mm, 0,47 mm, 0,50 mm, 0,65 mm and 1,00 mm. In particular, it gives general requirements, magnetic properties, geometric characteristics, tolerances and technological characteristics, as well as inspection procedure. The nominal thickness 0,47 mm applies to the grades for use at 60 Hz only.This document applies to cold-rolled non-oriented electrical steel strip and sheet supplied in the fully-processed state in coils or sheets, and intended for the construction of magnetic circuits. This document does not apply to materials delivered in the semi-processed state.They correspond to class C21 of IEC 60404-1.
