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:

Af = C where

C is 1940 for calculations using SI units and 625,000 for calculations using USC units;

Axc is the applicable tensile test piece cross-sectional area, expressed in square millimeters (square inches), as follows:

1) for circular cross-section test pieces, 130 mm2 (0.20 in.2) for 12.7 mm (0.500 in.) and 8.9 mm (0.350 in.) diameter test pieces; 65 mm2 (0.10 in.2) for 6.4 mm (0.250 in.) diameter test pieces;

2) for full-section test pieces, the lesser of a) 485 mm2 (0.75 in.2) 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 in.2);

3) for strip test pieces, the lesser of a) 485 mm2 (0.75 in.2) 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 in.2);
