Standard Test Method for Apparent Density of Non-Free-Flowing Metal Powders Using the Carney Funnel
ASTM B417-25
Organization:
ASTM - ASTM International
Year: 2025
Abstract: 5.1 This test method provides a guide for evaluation of an important physical characteristic of a powder known as the apparent density. The measured apparent density bears a relationship to the mass of powder that will fill a fixed volume die cavity. The degree of correlation between the results of this test and the performance of powders during use may vary with each particular application. Note, however, that the presence of moisture, oils, stearic acid, stearates, waxes, and the temperature of the powder mass may alter the physical characteristics of the powder. 5.2 Test Method B212, using the Hall flowmeter funnel, is the preferred method for determining the apparent density of metal powders and powder mixtures. The Carney flowmeter funnel of Test Method B417 should only be used when powder will not flow through the Hall flowmeter funnel.

| scope | 1.1 This 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. 1.2 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 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. 1.3 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. | |
