Designation: A781/A781M – 08

Standard Specification for

Castings, Steel and Alloy, Common Requirements, for

General Industrial Use1

This standard is issued under the fixed designation A781/A781M; the number immediately following the designation indicates the year

of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.

A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

1. Scope*

1.1 This specification covers a group of requirements that

are mandatory requirements of the following steel casting

specifications issued by ASTM. If the product specification

specifies different requirements, the product specification shall

prevail.

1.2 This specification also covers a group of supplementary

requirements that may be applied to the above specifications as

indicated therein. These are provided for use when additional

testing or inspection is desired and apply only when specified

individually by the purchaser in the order.

1.3 The requirements of the individual material specification,

and this general specification shall prevail in the sequence

named.

1.4 The values stated in either SI units or inch-pound units

are to be regarded separately as standard. The values stated in

each system may not be exact equivalents; therefore, each

system shall be used independently of the other. Combining

values from the two systems may result in non-conformance

with the standard.
