Elongation in 2 in. [50 mm], min, %: | ||||||||||||
Basic minimum elongation transverse strip tests, and for all small | 35 | 25 | 30 | 16.5 | 30 | 16.5 | ||||||
sizes tested in full section | ||||||||||||
When standard round 2-in. [50-mm] gage length test specimen is | 28 | 20 | 22 | 12 | 20 | 12 | ||||||
used | ||||||||||||
For longitudinal strip tests | A | A | A | |||||||||
For transverse strip tests, a deduction for each 1⁄32-in. [0.8-mm] | 1.25 | 1 | 1 | |||||||||
decrease in wall thickness below 5⁄16 in. [7.9 mm] from the basic | ||||||||||||
minimum elongation of the following percentage shall be made | ||||||||||||
A The minimum elongation in 2 in. [50 mm] shall be determined by the following equation: | ||||||||||||
e 5 625 000A0.2 / U 0.9 | ||||||||||||
for inch-pound units, and | ||||||||||||
e 5 1 940A0.2 / U 0.9 | ||||||||||||
for SI units, | ||||||||||||
where: | ||||||||||||
e = minimum elongation in 2 in. [50 mm], %, rounded to the nearest 0.5 %, | ||||||||||||
A = cross-sectional area of the tension test specimen, in.2 [mm2], based upon specified outside diameter or nominal specimen width and specified wall thickness, | ||||||||||||
rounded to the nearest 0.01 in. 2 [1 mm2]. (If the area thus calculated is equal to or greater than 0.75 in. 2 [500 mm2], then the value 0.75 in.2 [500 mm2] shall | ||||||||||||
be used.), and | ||||||||||||
U = specified tensile strength, psi [MPa]. |
