1.1 This specification covers aluminum and aluminum alloy flat sheet, coiled sheet, and plate in the alloys (Note 1) and tempers shown in Tables 2 and 3, and in the following finishes:
1.1.1 Plate in all alloys and sheet in heat-treatable alloys: mill finish.
1.1.2 Sheet in nonheat-treatable alloys: mill finish, one-side bright mill finish, standard one-side bright finish, and standard two-sides bright finish.
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System (UNS) alloy designations are those of Table 1 preceded by A9, for example, A91100 for aluminum 1100 in accordance with Practice E 527.
Note 18212;Throughout this specification, use of the term alloy in the general sense includes aluminum as well as aluminum alloy.
Note 28212;See Specification B 632/B 632M for Tread Plate.
Note 38212;See Specification B 928/B 928M for marine sheet and plate. Due to the additional corrosion testing required, it is not intended that Specification B 209M be used for marine sheet and plate.
1.3 This specification is the metric counterpart of Specification B 209.
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
