and specify the specific requirements of the selected PSL2 or PSL3 in the
contract.
According to the requirements of the purchaser, through negotiation between
the supplier and the purchaser, the hardenability, grain size, or other items can
be inspected. The specific requirements are stipulated by agreement between
both parties.
8 Dimensions, weight, tolerance, pipe ends, and
defects
8.1 Dimensions
