GENERAL NOTES:
(a)All dimensions are in mm.
(b)Tolerances are equal plus and minus except as noted.
NOTES:
(1)The inside diameter and the nominal wall thickness at ends are to be specified by the purchaser.
(2)A minimum wall thickness of 87.5% applies unless the purchaser specifies a different wall thickness toletance.
(3)Out-of-round is the sum of absolute values of plus and minus tolerances.
