Description
IEC 60404-3:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
