When these steel grades are ordered with the special tolerances given in Table 8, in case of dispute it is necessa
36、ry to verify that the wave height of any edge wave of length over 200 mm is always less than: 1 % of its length for a nominal sheet width 1500 mm; 1,5 % of its length for a nominal sheet width = 1500 mm. If the length of an edge wave is less than 200 mm it is necessary to verify that its maximum hei

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
46、 onto the sheets delivered.
