Note:

A. For rectangular bar, the Distance Between Parallel Surfaces as used in this table refers to the thickness.
B. Elongation values are based on 5.65 times the square root of the area for dimensions greater than 0.10 in. [2.5 mm]. In any case, a minimum gage length of 1 in. [25 mm] shall be used.
C. Yield strength at 0.2 % offset.
