42、projection of transverse edge over a longitudinal edge (see Figure 1). The out-of-squareness shall not exceed 1 % of the actual width of the sheet. 11 Tolerances on edge camber Edge camber (q) is the maximum distance between a longitudinal edge and a straight edge supported on the latter (see Figure

43、 1). Edge camber shall be measured on the concave edge. The basis of measurement shall be a distance of 2 m taken at any point on the edge. In the case of sheets and cut lengths with a length less than 2 m, the basis measurement shall be equal to their length. The edge camber shall not exceed 5 mm o

44、ver a length of 2 m. For lengths less than 2 metres, the edge camber shall not exceed 0,25 % of the actual length. For slit wide strip of width less than 600 mm a special edge camber tolerance (CS) of 2 mm maximum on a 2 m length may be specified. This special edge camber tolerance is not applicable

45、 to slit wide strip of high yield strength steels. 12 Superimposition of dimensions By agreement at the time of ordering, the tolerance on out-of-squareness and edge camber may be replaced by a requirement that a perfect rectangle formed by the ordered width and length dimensions can be superimposed
