Tensile Requirements (min)
   Tensile strength   psi (MPa)   
Yield strength  psi (MPa)
Elongation in 2 in. or 50 mm, %
A 48000 [330] 30000 [205] (Note 1, 2)
B 60000 [415]  35000 [240] 

Note:
1)The minimum elongation in 2 in. [50 mm] shall be that determined by the following equation:
e = 625 000 [1940] A0.2/U 0.9 
where:
e = minimum elongation in 2 in. or 50 mm in percent, rounded to the nearest percent,
A = the lesser of 0.75 in.2 [500 mm2] and the cross-sectional area of the tension test specimen,
calculated using the specified outside diameter of the pipe, or the nominal width of the tension test specimen and
the specified wall thickness of the pipe, with the calculated value rounded to the nearest 0.01 in.2 [1 mm2], and
U = specified minimum tensile strength, psi [MPa].

2)See below table for the minimum elongation values that are required for various combinations of tension test specimen size and specified minimum tensile strength.
