Measurement10.1 Unless otherwise stated, the measurement of the geo-metrical
39、 requirements shall be based on the definition outlinedin Section 10.10.2 ThicknessThe thickness (texture included) may bemeasured at any point located more than 20 mm from theedges.10.3 WidthThe width is measured perpendicularly to thelongitudinal axis of the product.10.4 LengthThe length is measur
40、ed along one of the sidesof the sheet or cut length.10.5 FlatnessThe measurement of the flatness deviation(pockets) is made according to the pictorial representation “A”and “B”, see Fig. 2. The sheet is lying on a flat surface with theconcave side upward.10.6 Edge CamberThe edge camber is the greate
41、st devia-tion of a side edge from a straight line, the measurement beingtaken on the concave side with a straight edge (see Fig. 3).11.
