ASTM A781/A781M-17

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: A781/A781M − 16 A781/A781M − 17
Standard Specification for
Castings, Steel and Alloy, Common Requirements, for
1
General Industrial Use
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,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-conformancenonconformance with the standard.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
