Scope*1.1 This specification covers high magnesium marine application
3、aluminum-alloy (productsNote 1), in those alloy-tempersshown in Table 2 Table 3 and Table 4 Table 5, for flat sheet, coiled sheet, and plate, in in the mill finish condition that areintended for marine hull construction and other marine applications where frequent or constant direct contact with sea
4、water isexpected and for similar environments (Note 21).Aluminum alloy products covered by this specification include the alloy-tempersof flat sheet, coiled sheet, and plate shown in Table 2 Table 3 and Table 4 Table 5, and alloy-tempers of extruded profiles shownin Table 6 Table 7.NOTE 1Throughout
5、this specification use of the term alloy in the general sense includes aluminum as well as aluminum alloy.NOTE 1There are other aluminum alloy-temper products that may be suitable for use in marine and similar environments, but which may not requirethe corrosion resistance testing specified by B928/
6、B928M. See Specification B209 or B209M for other aluminum sheet and plate alloy-temper products.For other aluminum extruded alloy-temper products see Specification B221 or B221M and/or other relevant specifications for aluminum extrudedproducts.1.2 Alloy and temper designations are in accordance wit
7、h ANSI H35.1/H35.1 (M). The equivalent Unified Numbering Systemalloy designations are those of Table 1 preceded by A9, for example, A95083 for 5083 in accordance with Practice 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 rega
8、rdedseparately as standard. The values stated in each system may not be exact equivalents; 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
9、and aluminum alloys in this specification, see Annex A2.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
