34、ing, if agreed at the time of enquiry and order (see Annex B, option f). The thickness (within one coil) shall change gradually and the changes shall not be discontinuous. NOTE For coils not slit in longitudinal direction the crown should be aimed to be as constant and symmetrical from the middle of

35、 the coil as possible. 7.2.3 More severe tolerances on thickness and crown may be agreed at the time of enquiry and order (see Annex B, option g).

For strip w 600 mm slit from wide strip, the tolerances on edge camber shall be agreed at the time

40、 of enquiry and order. 8 Measurement 8.1 General Measurements listed in 8.2 to 8.7 shall be used in case of dispute and be carried out at ambient temperature. 8.2 Thickness 8.2.1 The thickness shall be measured at any point situated at least 40 mm from the edges for products with mill edges and at l

41、east 25 mm from the edges for products with trimmed/slit edges. For coils with uncropped ends, 7.1 shall be considered. 8.2.2 The crown shall be measured as the thickness difference between the centre line of the product and a measuring point at 40 mm from any edge of the product in case of mill edg

42、es and at 25 mm in case of trimmed/slit edges. 8.2.3 The difference in thickness within one coil shall be measured at a line with an invariable distance from the longitudinal edges (minimum distance from the edges in accordance with 8.2.1). 8.3 Length of sheet/plate The length of the sheet/plate is

43、the length of the shorter of both longitudinal edges. 8.4 Width The width shall be measured at right angles to the longitudinal axis of the product. 8.5 Flatness for sheet/plate Deviation from flatness for sheet/plate shall be determined by measuring the deviation in distance between the product and

44、 a flat horizontal surface on which it is placed. 8.6 Edge camber The edge camber is the maximum deviation of a longitudinal edge from a straight edge measuring base applied to it. The camber is measured on the concave edge (see Figure 1). For sheet/plate measuring base shall be the length of the pr

45、oduct for a nominal length l 5 000 mm. For strip and sheet/plate with a nominal length l 5 000 mm, the measuring base shall be 5 000 mm, taken anywhere along the edge but excluding the uncropped ends.
