*Wall tolerance ± 10% of specified wall thickness.
Note 1: Ovality is the difference between maximum and minimum outside diameters measured at any one cross section. There is no additional tolerance for ovality on tubes having a specified wall thickness of more than 3% of the outside diameter.
Note 2: For sizes up to and including 5-in. outside diameter, an ovality tolerance of twice the tabular outside diameter tolerance spread shown is applied one half plus and one half minus to tubes having a specified wall thickness of 3% or less of the specified outside diameter. The average of maximum and minimum outside diameter readings should fall within the outside diameter tolerances as shown in this table.
Note 3: For sized over 5-in. to and including 16-in. outside diameter, when the specified wall thickness is 3% or less of the outside diameter, the ovality shall not exceed 1.5% of the specified outside diameter.

Squareness of Sides
±B = C X 0.006 where:
B = tolerance for out-of-square, and
C = length of longest side.
The straightness tolerance is 0.075 in. in 3 ft.
using a 3-ft. straightedge and feeler gauge.
