(1) Out-of-round is the sum of absolute values of plus and minus tolerance.
(2) This tolerance may be exceeded in localized areas of formed fittings where increased wall thickness is required to meet design requirements of para 2.2
(3) The inside diameter and the nominal wall thicknesses at ends are to be specified by the purchaser.
(4) Unless otherwise specified by the purchaser, these tolerances apply to the nominal inside diameter, which equals the difference between the nominal
outside diameter and twice the nominal wall thickness.
