ASTM B 417 : 2025

1.1This test method covers a procedure for determining the apparent density of non-free-flowing metal powders and powder mixtures. It is designed for those metal powders that do not freely flow through the Hall flowmeter funnel.

1.2Units—With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimeter (g/cm³) and gram (g) units is the long-standing industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3This 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.

1.4This 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.
