ASTM A48 is an internationally recognized standard specification that tells you it has met certain tensile strength requirements. A iron cast product that meets these standards may have a strength standard stamped on the item somewhere, usually indicated in either inch to pound units or in SI units (the International System of Units). ASTM A48 is a specification used for gray iron castings that are created for general engineering purposes.
