42、 running perpendicular to thelongitudinal axis of the product, with the measuring points being at least 20 mm from the longitudinal edges andat least 100 mm from the ends of the sheet or bar.8.3 Width shall be measured perpendicular to the longitudinal axis of the product.8.4 Product length, L, shal

44、the two ends of the measuring distance, with the measurement beingtaken on the concave side. A section of 50 mm at each end shall be excluded from measurement (see figure 2).8.7 Deviation from flatness shall be determined by laying the product on a flat horizontal surface so that it restsfreely unde

Deviation from flatness shall be measured as the maximum distance between the flatand the surface, or between the flat and a straightedge 1000 mm long.8.7.1 Deviation from flatness across the width shall be determined by means of a line perpendicular to thelongitudinal axis of the pr
