Tabulated tolerances can be applied simultaneously to only two of three dimensions, i.e., ODxWall or IDxWall. ID Tolerances apply only to tube specified ODxID or IDxWall...and to dimensions 0.625" and over when ID is at least half the OD. Wall thickness less than 3% of OD, require added ovality tolerances of plus and minus 1/2% of mean OD. If water quench and temper is required or specified-refer to Mill for applicable tolerance.
