1.1 This specification covers pearlitic malleable iron castings for general engineering usage at temperatures from normal ambient to approximately 750&#176F.

1.1.1 For continuous service at temperatures up to 1200&#176F design factors should be incorporated to compensate for possible property changes, as demonstrated by Marshall and Sommer<b> </b> and by Pearson.<b> </b></p> <p>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.</p> <p>1.3 The values stated are in inch-pound units and are to be regarded as the standard. A complete metric companion specification A220M has been developed; therefore, no metric equivalents are shown in this specification.</p>
