Elongation in 2 in. or 50 mmA, BA, B
The minimum elongation in  2  in.  [50  mm]  shall  be determined  by  the following equation:
e = 625000 [ 1940] A 0.2/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].
B        See  Table  X4.1  or  Table  X4.2,  whichever  is  applicable,  for  the  minimum
elongation values that are required for various combinations of tension test specimen size and specified minimum tensile strength.
