This part of IEC 60404 specifies the measurement and test methods for the determination of the following geometrical characteristics of electrical steel strip and sheet:
- edge wave (wave factor);
- residual curvature;
- edge camber;
- deviation from the shearing line (internal stress);
- burr height.
This document applies to electrical steel strip and sheet intended for the construction of magnetic circuits and corresponding to Classes B2, C21, C22 and C23 of IEC 60404-1.
