The minimum elongation in 2 in. (50.8 mm) shall be that determined by the following equation:
U.S.Customary Unit Equation: e= 625,000*A0.2/U0.9; SI Unit Equation: e= 1,944A0.2/U0.9
Where e= minimum elongation in 2 in. (50.8 mm) in percent rounded to the nearest percent.
A= applicable tensile test specimen area, as follows:
For round bar specimens:
-----0.20 in.2 (130 mm2) for the 0.500 in. and 0.350 in. specimens,
-----0.10 in.2 (65 mm2) for the 0.250 in. specimen
b. For full section specimens, the smaller of (i) 0.75 in.2(485 mm2) and (ii) the cross-sectional area of the test specimen, calculated using the specified outside diameter of the pipe and the specified wall thickness of the pipe, rounded to the nearest 0.01 in.2(10 mm2);
c. For strip specimens, the smaller of (i) 0.75 in.2 (485 mm2) and (ii) the cross-sectional area of the test specimen, calculated using the specified width of the test specimen and the specified wall thickness of the pipe, rounded to the nearest 0.01 in.2 (10 mm2).
U = speciÞed minimum ultimate tensile strength in psi (MPa).
