1. Outside Diameter-Based on circumferential measurement ±0.5% of the specified outside diameter.
2. Out-of-Roundness-Difference between major and minor outside diameters.
3. Alignment-Using a 10 ft (3m) straightedge placed so that both ends are in contact with the pipe, 1/8 in. (3mm).
4. Thickness-The minimum wall thickness at any point in the pipe shall not be more than 0.01 in. (0.3mm) under the specified nominal thickness.
5. Lengths with unmachined ends shall be within -0,+1/2 in. (-0,+13mm) of that specified. Lengths with machined ends shall be as agreed upon between the manufacturer and the purchaser.
