Flatness tolerances shall be as given in Tables 8 and 9. The measurement of wavi
17、ness is only made on sheet edges. The flatness tolerances apply only to sheet. Flatness tolerances closer than special tolerances _ may be agreed at the time of enquiry and order.

21、t-of-squareness The out-of-squareness u is the orthogonal 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. Figure 1 Out-of-squareness u and edge camber q 11 Tolerances on edge camber The edge camber q
22、is the maximum distance between a longitudinal edge and a straight edge supported on the latter (see Figure 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 l
23、ess than 2 m, the basis measurement shall be equal to their length. EN 10143:2006 (E) 13 The edge camber shall not exceed 5 mm over a length of 2 m. For lengths less than 2 m, the edge camber shall not exceed 0,25 % of the actual length. For slit wide strip of width 600 mm a special edge camber tole
24、rance (CS) of 2 mm maximum on a length of 2 m may be specified. This special edge camber tolerance is not applicable for steels with specified minimum proof strength Rp0,2 280 MPa. 12 Superimposition of dimensions By agreement at the time of enquiry and order the tolerance on out-of-squareness and e
25、dge camber may be replaced by a requirement that a perfect rectangle formed by the ordered width and length dimensions can be superimposed onto the sheets delivered.
