Permissible Variations in Dimensions
Outside Diameter-- Based on circumferential measurement, ±0.5% of the specified outside diameter
Out-of-Roundness-- Difference between major and minor outside diameters, 1%
Alignment-- Using a 10-ft [3-m] straightedge placed so that both ends are in contact with the pipe, 1/8 in [3mm] deviation from contact with the pipe
Thickness-- The minimum wall thickness at any point in the pipe shall not be more than 0.01 in [0.3mm] under the nominal thickness
