ASTM B 311 : 2013

1.1This test method covers the determination of density for powder metallurgy (PM) materials containing less than two percent porosity and for cemented carbides. This test method is based on the water displacement method.

1.2With 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 SI units are to be regarded as 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 and health practices and determine the applicability of regulatory limitations prior to use.
