3 Process (seamless (SML) or welded (WLD), or deep cold worked (HCW)).
4 levels, materials, specifications.
5 dimensions (NIS or outside diameter and pipe wall number or average wall thickness).
6 Length (fixed length or non-fixed length).
7 Pipe end processing (see the A999/A999M standard pipe end processing section).
8 Selection requirements (finished product analysis: hydraulic or non-destructive testing).
9 test report required (see the A999/A999M standard quality certificate section).
10 standard size.
11 Selected special requirements or any supplementary requirements, or both.
