    Radiographic Examination
    We will employ radiography as a production control on the welding employed in the manufacture of pipe to this specification. 
    Permissible Variations in Dimensions
    Outside Diameter—60.5 % of the specified outside diameter for the outside diameter based on circumferential measurement, except that in sizes 24 in. (610 mm) and smaller this tolerance shall be 6 1 ⁄ 8 in. (3.2 mm).
    Out-of-Roundness—1 %, that is, the difference between the major and minor outside diameter.
    Thickness—The minimum wall thickness shall not be more than 0.01 in. (0.25 mm) under the specified thickness. Localized (isolated and noncontinuous) reductions in wall thickness caused by noninjurious surface defects may be permitted up to a depth not exceeding 6 1 ⁄ 2 % the specified pipe wall thickness.
    The width of the end is 1 ⁄ 16 in. (1.6 mm) with a tolerance of 6 1 ⁄ 32 in. (0.8 mm).
    The end of the pipe is not be out of square more than 1 ⁄ 16 in. (1.6 mm).
