ASTM B62

This specification establishes requirements for an alloy having a composition of copper, tin, lead, and zinc which is used for component castings of valves, flanges, and fittings. The specimen shall have the chemical composition of major elements: copper, tin, lead zinc, nickel including cobalt. It must also be comprised of the following residual elements: iron, antimony, sulfur, phosphorus, aluminum, and silicon. Mechanical properties shall be determined from separately cast test bars. Castings shall not be repaired, plugged, welded or burned-in. Valves, flanges, and fittings shall be marked accordingly in such position as not to injure the usefulness of the casting.
