ASTM International Standard Test Method for Apparent Density of Metal Powders and Related Compounds Using the Arnold Meter ASTM B703-21

1.1 This test method covers a quantitative laboratory procedure for determining the apparent density of both free-flowing and non-free-flowing metal powders, lubricated metal powder mixtures, and powder compounds. 1.2 Units\u2014With the exception of the values for mass, volume, and density, for which the use of the gram and the cubic centimetre units is the long-standing industry practice, the values stated 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.
