IEC 60404-3:2022 is available as IEC 60404-3:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60404-3:2022 is applicable to grain-oriented and non-oriented electrical steel strip and sheet for measurement of AC magnetic properties at power frequencies. The object of this document is to define the general principles and the technical details of the measurement of the magnetic properties of electrical steel strip and sheet by means of a single sheet tester (SST). This edition includes the following significant technical changes with respect to the previous edition:
- Annex A was revised. The method of determining the yokes’ lamination resistance was added to Annex A;
- Annex B of the consolidated version of 2010 referred to calibration of the SST using the Epstein method. It was cancelled;
- Annex B (new), Annex C and Annex D were revised, they are for information only;
- Annex C was modified taking account of the new situation regarding P and R grades;
- Annex D was amended by addition of Clause D.4 on the numerical air flux compensation.
