IEC 60404-9-2018 磁性材料--第9部分:磁性钢片和钢带几何特性的测定方法 Magnetic materials – Part 9: Methods of determination of the geometrical characteristics of electrical steel strip and sheet

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.
