A-Minimum and maximum limits apply to tests taken both longitudinal and transverse to the direction of rolling.  Mechanical properties for conditions other than annealed or plate thickness over 1 in. (25 mm) may be established by agreement between the manufacturer and the purchaser.

B– T equals the thickness of the bend test specimen.  Bend tests are not applicable to material over 0.187 in (4.75 min) in thickness.

C– For Grades 5, 6 and 32 the elongation on materials under 0.025 in. (0.635 mm) in thickness may be obtained only by negotiation.

D– Elongation for continuous rolled and annealed (strip product from coil) for Grade 9 and Grade 18 shall be 12% minimum in the longitudinal direction and 8% minimum in the transverse direction.

E– Properties for material in the solution treated condition.

F– Material is normally purchased in the solution treated condition.  Therefore, properties for aged material shall be negotiated between manufacturer and purchaser.
