ASTM B 632/B632M : 2024

1.1This specification covers aluminum-alloy rolled flat tread plate, mill-finish, with a raised pattern on one side, in the alloy, tempers, and thicknesses shown in Table 1 and Table 2 [Table 3].

1.2Alloy and temper designation are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designation shall be in accordance with Practice E527.

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

1.4The values stated in either inch-pound or SI units are to be regarded separately as standard. The SI units are shown either in brackets or in separate tables. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems will result in nonconformance with the specification.

1.5This 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.
