4 Test methods

4.1.3 The judgement of the analytical value is based on the round-off comparison method. The rules of rounding off for numerical values shall be in accordance with the relevant provisions of GB/T 8170. The round-off digits shall be consistent with the limit digits specified in GB/T 3190.

5 Inspection rules

5.6.2 When the dimensional tolerances of any sample are unqualified, the coil of strips represented by this sample is judged to be unqualified.

5.6.3 When the room-temperature tensile mechanical properties of any sample are unqualified, a double quantity of samples shall be taken from this lot of strips (including the coil of strips represented by this unqualified sample) for repeated test. If the repeated test results are all qualified, this lot of strips is judged to be qualified. If there is still sample with unqualified properties in the repeated test results, this lot of strips is judged to be unqualified. After negotiation between the supplier and the purchaser, the supplier is allowed to inspect on a coil-by-coil basis and deliver qualified ones.

5.6.4 If the appearance quality of any coil of strips is unqualified, this coil is judged to be unqualified.
