ANSI/ASTM E230

ANSI/ASTM E230 is a standard that outlines how to accurately measure and report the dimensions of a steel reinforcing bar, known as rebar, used in construction. It defines the methods for determining the bar's diameter and surface markings to ensure consistency and quality. This helps engineers, builders, and inspectors verify that rebar meets specified size requirements, ensuring the structural integrity and safety of concrete structures like buildings and bridges. By following these guidelines, all parties can communicate and confirm rebar specifications reliably.
