These requirements apply to the casting specifications to the extent referenced therein.

1.2 The chemical composition and other requirements not included in this specification shall be prescribed in the casting product specifications.

1.3 Units-The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 No precise quantitative relationship can be stated between the properties of the metal in various locations of the same casting or between the properties of castings and those of a test bar casting from the same metal. (See Appendix X1.)2
