This standard specifies the classification and designation, technical requirements, test methods, inspection rules, identification of castings, surface protection, packaging and storage and transportation requirements for malleable iron castings. This standard applies to malleable iron castings cast in sand molds or molds with comparable thermal conductivity to sand molds. Other mold casting malleable iron castings can also be used as a reference.
