1.1 本试验方法规定了一种测定金属粉末和化合物堆积密度（堆积密度）的方法，即在规定条件下在容器中堆积的粉末的密度。 1.2 单位-- 除用于确定密度的密度和质量值外，使用克每立方厘米（g/cm2） 3. )克（g）单位是长期的行业惯例，SI单位的值应被视为标准。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 4.1 本试验方法包括评估金属粉末和相关化合物的堆积密度物理特性。在容器被敲击、振动或以其他方式搅拌的情况下，测量的振实密度与填充固定体积模腔或其他容器的粉末质量有关。本试验方法的结果与所用粉末质量之间的相关性程度因具体应用而异，尚未完全确定。

1.1 This test method specifies a method for the determination of tap density (packed density) of metal powders and compounds, that is, the density of a powder that has been tapped, to settle contents, in a container under specified conditions. 1.2 Units— With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm 3 ) and gram (g) units is the long-standing industry practice, the values in SI units are to be regarded as standard. 1.3 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. 1.4 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. ====== Significance And Use ====== 4.1 This test method covers the evaluation of the tap density physical characteristic of metal powders and related compounds. The measured tap density bears a relationship to the mass of powder that will fill a fixed volume die cavity or other container in situations where the container is tapped, vibrated, or otherwise agitated. The degree of correlation between the results of this test method and the quality of powders in use will vary with each particular application and has not been fully determined.
