42、ished at the mill before subsequent swaging, expanding, bending, polishing, or otherfabricating operations.BOvality is the difference between maximum and minimum outside diameter measured at any one cross section. There is no additional tolerance for ovality on materialhaving a nominal wall thicknes
43、s of more than 3 % of the outside diameter. On this material, the average of maximum and minimum outside diameter measurements willfall within the outside diameter tolerance shown in the table above. An additional ovality allowance of twice the outside diameter tolerance spreads shown above, applied
44、one half plus and one half minus, is allowed for material having nominal wall thickness of 3 % or less of nominal outside diameter.TABLE 5 Permissible Variations in LengthAOutside Diameterin.
