This European Standard is intended to define the test methods used for the determination of the following geometrical characteristics of electrical steel sheet and strip:
- edge wave (wave factor);
- residual curvature;
- edge camber;
- deviation from the shearing line due to internal stresses;
- burr height of cut edges.
This European Standard applies to electrical steel sheet and strip intended for the construction of magnetic circuits and corresponding to Clauses B2, C21 and C22 of IEC 60404-1:2000.
