in 2 in. [50 mm] 10 [10]D
in 4D [5D or 5.65 yA ] 10 [9]c Elongations in 2 in. [50 mm] apply for profiles tested in full section and for sheet-type specimens machined from material up through 0.500 in. [12.5 mm] in thickness having parallel surfaces. Elongations in 4D [5D or 5.65 \/A], where D and A are diameter and cross-sectional area of the specimen, respectively, apply to round test specimens machined from thicknesses over 0.250 in. [6.30 mm].
dFor thicknesses less than 0.250 in. [up through 6.30 mm] the minimum elongation is 8 %.
