1、Designation: B 26/B 26M 09Standard Specification forAluminum-Alloy Sand Castings1This standard is issued under the fixed designation B 26/B 26M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.

3、ed as shown in Table 1.1.2 This specification is not intended for aluminum-alloysand castings used in aerospace applications.1.3 Alloy and temper designations are in accordance withANSI H35.1/H35.1M. Unified Numbering System alloy des-ignations are in accordance with Practice E 527.1.4 Unless the or
4、der specifies the “M” specification desig-nation, the material shall be furnished to the inch-pound units.1.5 For acceptance criteria for inclusion of new aluminumand aluminum alloys and their properties in this specification,see Annex A1 and Annex A2.1.6 The values stated in either SI units or inch
5、-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.7 This standard does not purport
6、to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
