a    For intermediate grades, the difference between the specified maximum yield strength and the specified minimum yield strength shall be as given in the table for the next higher grade, and the difference between the specified minimum tensile strength and the specified minimum yield strength shall be as given in the table for the next higher grade, For intermediate gradesup tp Grade L320 or X46, the tensile strength shall be ≤ 655 MPa (95  000 psi). For intermediate grades greater than Grade L320 or X46 and lower than Grade L555 or X80, the tensile strength shall be ≤ 760 MPa (110 200 psi). For intermediate grades higher than Grade L555 or X80, the maximum permissible tensile strength shall be obtained by interpolation. For SI units, the calculated value shall be rounded to the nearest 5 MPa. For USC units, the calculated value shall be rounded to the nearest 100 psi.
b   For grades >L625 or X90, Rp0,2 applies.
c   This limit applies for pipe with D >323, 9 mm (12.750 in).
d   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).
e   For pipe requiring longitudinal testing, the maximum yield strength shall be ≤ 495 MPa (71 800 psi).
f    The specified minimum elongation, Af,   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 millimeters (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).
g    Lower values of Rto,5/Rm may be specified by agreement.
h    For grades > L625 or X90, Rp0,2/Rm applies. Lower values of Rp0,2/Rm may be specified by agreement.
