1.1 This specification covers malleable irons for castings made by the cupola process.
1.2 Without knowledge of casting geometry and process details, no quantitative relationship can be stated between the properties of the iron in the various locations of a casting and those of a test bar cast from the same iron.
1.3 The values stated are in inch-pound units and are to be regarded as the standard. A complete metric companion Specification A197M has been developed; therefore, no metric equivalents are shown in this specification.
