    17、nd fittings shall be iron castings suitable for installation and service for sanitary, storm drain, waste, and ventpiping applications. The pipe and fittings shall meet all applicable requirements and tests given in this specification.4.2 The castings shall be made of cast iron, produced by an estab

    18、lished commercial method that provides control over chemicaland physical properties. Cast iron is a generic term for a series of alloys as defined in Terminology A644 and includes gray ironas well as ductile iron. The castings shall be sound, true to pattern, and of compact close grain that permits

    19、drilling and cuttingby ordinary methods. The interior surface shall be reasonably smooth and free from defects that would make the castings unfit forthe use for which they are intended.4.3 To minimize the possibility of introducing radioactive material to a melting operation, ferrous scrap, pig iron

    20、, and anyrecycled ferrous material shall be screened for radioactivity with suitable detection devices operated in accordance with thedetection manufacturers instructions. Written operating and maintenance procedures for the detection equipment shall be providedto the purchaser for review when reque
