1.1本试验方法涵盖了测定非自由流动金属粉末表观密度的程序。它是为那些不能自由流过霍尔流量计漏斗的金属粉末而设计的。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法为评估粉末的表观密度物理特性提供了指南。测得的密度与制造零件时填充固定体积模腔的粉末质量有关。本试验方法的结果与所用粉末质量之间的相关性程度将因具体应用而异。

1.1 This test method covers a procedure for determining the apparent density of non-free-flowing metal powders. It is designed for those metal powders that do not freely flow through the Hall flowmeter funnel. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method provides a guide for evaluation of the apparent density physical characteristic of powders. The density measured bears a relationship to the mass of powder that will fill a fixed volume die cavity when parts are being made. The degree of correlation between the results of this test method and the quality of powders in use will vary with each particular application.
