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 high magnesium marine application aluminum-
3、alloy (Note 1), in those alloy-tempers shown inTable 2 Table 3 andTable 4 Table 5, for flat sheet, coiled sheet, and plate, in the mill finish condition that are intended for marinehull construction and other marine applications where frequent or constant direct contact with seawater is expected and
4、 for similarenvironments (Note 2).NOTE 1Throughout this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.NOTE 2There are other aluminum alloy-temper products that may be suitable for use in marine and similar environments, but which may not require
5、the corrosion resistance testing specified by B928/B928M. See Specification B209 or B209M for other aluminum sheet and plate alloy-temper products.1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M).H35.1/H35.1 (M). The equivalent UnifiedNumbering System alloy designations a
6、re those of Table 1 preceded by A9, for example, A95083 for 5083 in accordance withPractice E527.1.3 The values stated in either SI units (Table 3 and Table 5) or inch-pound units (Table 2 and Table 4) are to be regardedseparately as standard. The values stated in each system may not be exact equiva
7、lents; therefore, each system shall be usedindependently of each other. Combining values from the two systems may result in non-conformance with the standard.1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.1.5 This standard does not p
8、urport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
