This Standard 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 Standard applies to electrical steel strip and sheet specified in JIS C 2552 and JIS C 2553, and those corresponding to Classes B2, C21, C22 and C23 of IEC 60404-1:2016.
NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.
