1. Scope
1.1 This specification covers gray iron castings intended for general engineering use where tensile strength is a major consideration. Castings are classified on the basis of the tensile strength of the iron in separately cast test bars.
1.1.1 This specification subordinates chemical composition to tensile strength.
1.2 No precise quantitative relationship can be stated between the properties of iron in the various locations of the same casting and those of a test bar cast from the same iron (see Appendix).
1.3 The values stated in SI units are to be regarded as the standard.
