ASTM A615: Permissible Variation in Weight [Mass]

Deformed reinforcing bars shall be evaluated on the basis of nominal weight [mass]. The weight [mass] determined using the measured weight [mass] of the test specimen and rounding …….shall be at least 94 % of the applicable weight [mass] per unit length. In no case shall overweight [excess mass] of any deformed bar be the cause for rejection.
