If the purchaser has any requirement for chemical components, it shall be as agreed on when an order is placed. For the cross-reference table of similar domestic 7 Dimensions and shape - - Appropriate measuring instruments 7.3 r90 is calculated at 15% of strain; when average elongation is less than 15%, strain is calculated at the end of average elongation. n90 is calculated from the strain range of 10% ~ 20%; when average elongation is less than 20%, the strain range is the strain from 10% to the end of average elongation. 8 Inspection rules 8.1 Inspection and acceptance of steel plates (sheets) and strips shall be carried out by the inspection department of the supplier. 8.2 Steel plates (sheets) and strips shall be accepted by batch. Each batch for inspection shall consist of steel plates (sheets) and strips of same designation, same specification and same processing condition. Weight of each batch shall not be greater than 30 t; for steel strips with a coil weight greater than 30 t, each coil is a batch for inspection. 8.3 Sample numbers and sample methods of steel plates (sheets) and strip shall be as specified in Table 7. 8.4 Reinspection and criteria for steel plates (sheets) and strips shall be as specified in GB/T 17505. 8.5 Test results of chemical components and mechanical properties shall be rounded off using the rounded-off value comparison method; the rules for rounding off shall be as specified in GB/T 8170. 9 Packaging, marking and quality certification Packaging, marking and quality certification of steel plates (sheets) and strips shall be as specified in GB/T 247. If the purchaser has special requirements for packaging, they shall be as agreed on during ordering. ......
