1.1 本规范涵盖了使用混合材料制成的铝粉冶金结构件。 1.2 本规范涵盖了材料名称代码，其中包括材料的化学成分，其保证最小值为0.2 % 偏移屈服强度或极限抗拉强度，以及材料的回火条件。 1.3 单位- 密度值除外，其g/cm 3. 单位为行业标准，以英寸-磅单位表示的属性值为标准。国际单位制数值是由转换产生的，仅供参考，不被视为标准值。 1.4 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。 1.5 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 covers aluminum powder metallurgy structural parts made using admixed materials. 1.2 This specification covers a material designation code that includes the chemical composition of the material, its guaranteed minimum 0.2 % offset yield strength or ultimate tensile strength, and the temper condition of the material. 1.3 Units— With the exception of density values for which the g/cm 3 unit is the industry standard, property values stated in inch-pound units are to be regarded as standard. Values in SI units result from conversion, are only for information, and are not considered standard. 1.4 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. 1.5 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.
