This specification covers refined gold of Grades 99.5, 99.95, 99.99, and 99.995 in cast bar forms. Other forms of unfabricated gold of commerce are not to be excluded under this specification. The metal may be produced by any refining process that yields products capable of meeting the specified chemical composition requirements. Chemical assessment samples may be taken from the melt before pouring and shall be in the form of shots or pins, or by other alternative means on agreement between the manufacturer and purchaser.
