ASee the Orientation subsection in the Tension Tests section of Specification A6/A6M.
BElongation not required to be determined for floor plate.
CFor plates wider than 24 in. [600 mm] the elongation requirement is reduced two percentage points. See the Elongation Requirement Adjustments subsection in the Tension Tests section of Specification A6/A6M.
DFor wide flange shapes over 426 lb/ft [634 kg/m], elongation in 2 in. [50 mm] of 18 % minimum applies.
