Other characteristics and tolerances Residual curvature   Edge camber   Max. distance for a sample 500 mm in length applicable for width > 150 mm 35 mm Max. edge camber for a measuring length of 1,500 mm applicable for width > 150 mm 0.5 mm Deviation from the shearing line due to internal stresses   Flatness (wave factor)   Max. measured gap within a strip length of 1,500 mm applicable for width > 500 mm 1.0 mm Max. wave factor applicable for width > 150mm 1.5% The measuring methods for thickness and width are given in the product standards EN 10107 and IEC 60404-8-7. All other measuring methods and definitions are given in EN10251 and IEC 60404-9. The quoted values are in many cases better than those specified in the EN or IEC-Norm. Burr height (only for slit width)   Max. burr height 0.025 mm
