Scope

1.1 This specification2 covers aluminum-alloy (Note 1) die forgings, hand forgings, and rolled ring forgings as shown in Table 2, Table 3, and Table 4 in Section 10 for heat-treatable alloy forgings supplied in the F and 01 tempers. The maximum thicknesses for forgings within the scope of this specification are as indicated in those tables. NOTE 1—Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy. NOTE 2—For forging stock supplied as rolled, cold-finished bar, extruded bar, or rod see Specification B211/B211M. 1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E527. 1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2. 1.4 This specification is the inch-pound companion to Specification B247M; therefore, no SI equivalents are presented in the specification. 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.
