Out-of-roundness tolerances apply to maximum and minimum diameters as measured with a bar gauge, caliper, or device measuring actual maximum and minimum diameters.
The average diameter (as measured with a diameter tape) of one end of pipe shall not differ by more than 3/32 in. (2.38 mm) from that of the other end.

Notes:
1. Weight tolerances apply to the calculated weights for threaded-and-coupled pipe and to the tabulated or calculated weights for plain-end pipe. Where negative wall thickness tolerances smaller than those listed in above table are specified by the purchaser, the plus weight tolerance for single lengths shall be increased to 22.5 percent less the wail thickness negative tolerance.
2. For carloads composed of pipe from more than one order item, the carload tolerances are to be applied on an individual order item basis.
3. The tolerance for order items apply to the overall quantity of pipe shipped for the order item.
