IEC 60404-8-4:2022 is available as IEC 60404-8-4:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60404-8-4:2022 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, i.e. the final annealed condition, in coils or sheets, and intended for the construction of magnetic circuits. This document does not apply to materials supplied in the semi-processed state. This edition includes the following significant technical changes with respect to the previous edition:全文を表示する
- modification of terms and technical requirements concerning geometrical characteristics to be consistent with IEC 60404-9:2018;
- insertion of Table 3 - Tolerances on nominal thickness;
- change of the length of test specimen for determination of geometrical characteristics from 2 m to 1 m.
