(1) In any case, a minimum gage length of 1 in. [25mm] shall be used. SI elongation values are based on a gage length of 5.65 times the square root of the area for dimentions greater than 2.5 mm.
(2) Determined on the cross section midway between surface and center.
(3) Rockwell hardness requirements are not established for diameters less than 1/2 in. [12 mm].
