NOTES:

(1) When standard round 2 in. or 50 mm gage length or smaller proportionally sized specimens with gage length equal to 4D (4

times the diameter) is used, the minimum elongation shall be 22% for all ferritic grades except 18Cr-2Mo, T23 and T91.

(2) For longitudinal strip tests, a deduction from the basic minimum
