Note – The Minimum elongation in 50.80mm shall be that determined by the following formula:

Where
e – minimum elongation in 50.80 min in percent rounded to the nearest half percent;

A – cross sectional area of tensile test specimen in square millimeters, based on specified outside diameter or nominal specimen width and specified wall thickness rounded to the nearest 6 sq. mm or 484 mm2 whichever is smaller; and

U – specified tensile strength, MPa
