The steel strip shall be delivered, according to the actual weight. take the specimen, which has a width equal to the width of steel strip. Under such conditions, it is exempted from the determination of elongation at break. 8 Inspection rules 8.1 Steel strips shall be accepted in batches. Each batch of steel strips shall consist of steel strips of the same heat number, same dimension, same state, same category, which is classified according to Chapter 4 of this standard. 8.2 For each test, take one specimen from each of the inner end and the outer end of each coil of steel strip, OR take one specimen from each of the two steel strips, which are taken from each selected bundle. 8.3 The re-inspection and judgment of the steel strip shall be carried out, in accordance with the provisions of GB/T 17505. 8.4 Take out 5% steel coils/bundles from each batch, but not less than 4 coils (bundles), to check for unevenness and sickle bend. If there is one coil unqualified, this batch of steel strips shall be checked coil/bundle by coil/bundle; only the qualified coil/bundle is accepted. 9 Packaging, marking, quality certificate of steel strip The packaging, marking, quality certificate of the steel strip shall be implemented, in accordance with GB/T 247. 10 Numerical rounding off The numerical rounding of the inspection results of steel strip shall be in accordance with the provisions of YB/T 081. ......
