The pipe and fittings shall meet all applicable requirements and tests given in this specification.4.2 The castings shall be made of cast
19、 iron, produced by an established 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 compac
