This specification covers aluminum and aluminum alloy flat sheet, coiled sheet, and plate in the alloys and tempers in the following finishes: Plate in all alloys and sheet in heat-treatable alloys which are mill finished; and sheet in non heat-treatable alloys which are mill finished, one-side bright mill finished, standard one-side bright finished, and standard two-sides bright finished. The producer is responsible for the performance of all inspection and test requirements unless specified in the contract. The material shall be supplied in the mill finish and shall be uniform as defined by the requirements of this specification and shall be commercially sound. Each sheet and plate shall be examined to determine conformance to this specification with respect to general quality and identification marking. Sheet and plate shall be capable of being bent cold through a specified angle around a pin without cracking for the different alloys, tempers, and thicknesses. The plates shall exhibit no evidence of stress-corrosion cracking. For lot-acceptance purposes, resistance to exfoliation corrosion for each lot of material in the alloys and tempers shall be established by testing the previously selected tension-test samples to the criteria. The material shall be packaged to provide adequate protection during normal handling and transportation and each package shall contain only one size, alloy, and temper of material unless otherwise agreed.

1.1 This specification2 covers aluminum and aluminum-alloy flat sheet, coiled sheet, and plate in the alloys (Note 1) and tempers shown in Tables 2, 3, 4, and 5, 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/H35.1M. 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.

Note 1: Throughout this specification, use of the term alloy in the general sense includes aluminum as well as aluminum alloy.

Note 2: See Specification B632/B632M for tread plate.

Note 3: See Specification B928/B928M for 5xxx-H116 and 5xxx-H321 aluminum alloys containing 3 % or more nominal magnesium and intended for marine service and similar environments. Other alloy-temper products listed in this specification, which do not require the additional corrosion testing/capability called out in Specification B928/B928M, may be suitable for marine and similar environment applications.

1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 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.
