1.1 本规范 2. 包括铝和铝合金平板、卷材和合金中的板材( 注1 )和表2、3、4和5所示的回火，以及以下饰面: 1.1.1 所有合金板材和可热处理合金板材:轧制表面。 1.1.2 非热处理合金板材:轧制表面、单面光亮轧制表面、标准单面光亮表面和标准双面光亮表面。 1.2 合金和回火名称符合ANSI H35.1/H35.1M。等效的统一编号系统合金名称是表1中前面带有A9的合金名称，例如，根据惯例，A91100用于铝1100 E527 . 注1: 在本规范中，术语的使用 合金 一般来说，包括铝以及铝合金。 注2: 见规范 B632/B632M 用于踏板。 注3: 见规范 B928/B928M 对于5xxx-H116和5xxx-H321铝合金，含3 % 或更标称的镁，用于海上服务和类似环境。本规范中列出的其他合金回火产品，不需要规范中规定的额外腐蚀测试/性能 B928/B928M ，可能适用于海洋和类似环境应用。 1.3 有关本规范中包含新铝和铝合金的验收标准，请参阅 附件A2 . 1.4 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification 2 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.
