be composed of same designation, same specification and same process
status. Each batch of weight shall not be more than 30t. For the steel strip of
which the roll-weight is greater than 30t, each roll is deemed as an inspection
batch.
7.6 For tensile test, plastic strain ratio (r-value) and strain hardening index (n-
value) test, if there is 1 item’s test result not in accordance with the standard’s
requirements, then take double quantity of test samples from the same batch
for re-inspection of that item.
8 Packaging, mark and quality certificate
Packaging, mark and quality certificate of steel plate and strip shall be in
accordance with the provision of Q/BQB 400.
9 Rules of rounding off
