a   For intermediate grades, the difference between the specified minimum tensile strength and the specified minimum yield strength for the pipe body shall be as given in the table for the next higher grade.
b   For intermediate grades, the specified minimum tensile strength for the weld seam shall be the same value as was determined for the pipe body using footnote a).
c   The specified minimum elongation, A_f expressed in percent and rounded to the nearest percent, shall be as determined using the following equation;

         

where

  C    is 1 940 for calculations using SI units and 625 000 for calculations using USC units;

  A_xc is the applicable tensile test piece cross-sectional area, expressed in square millimetres (square inches), as follows:
      --- for circular cross-section test pieces, 130 mm² (0.20 in²) for 12,5 mm (0.500 in) and 8,9 mm (0.350 in) diameter test pieces; and 65 mm²(0.10 in²) for 6,4 mm (0.250 in) diameter test pieces;
      --- for full-section test pieces, the lesser of a) 485 mm² (0.75 in²) and b) the cross-sectional area of the test piece, derived using the specified outside diameter and the specified wall thickness of the pipe, rounded to the nearest 10 mm² (0.01 in²);
      --- for strip test pieces, the lesser of a) 485 mm² (0.75 in²) and b) the cross-sectional area of the test piece, derived using the specified width of the test piece and the specified wall thickness of the pipe, rounded to the nearest 10 mm²(0.01 in²);
   U   is the specified minimum tensile strength, expressed in megapascals (pounds per square inch).
