All dimensions are in inches and millimetres. (1 in. = 25.4 mm.)
B
The minimum is the lowest wall thickness at any cross section. The maximum permitted wall thickness, at any cross section, is the minimum wall thickness plus the
stated tolerance. All wall tolerances are on the plus side of the minimum requirement.
C
The maximum out-of-roundness applies to the average measured outside diameter.
