A Measured at 0.2 % offset or O.S % extension under load as described in Section 13 of Methods A 370.
B Elongation and reduction of area not required to be determined for floor plates.
C For plates tested in the transverse direction, the elongation minimum percent is reduced by 2 % and the reduction of
area minimum requirement is reduced by S %.
D See Section 7.
E When measured on the Fig. 4 (Methods A 370) l’h-in. (40-mm) wide specimen (see Note 2 above), the elongation is
determined in a 2-in. or SO-mm gage length which includes the fracture and shows the greatest elongation.
