scope:
This standard describes a procedure for determining the density of powder metallurgy (PM) products, including cemented carbides that generally contain less than two percent porosity. The method is based on Archimedes' principle.
NOTE 1-A test specimen that gains mass when immersed in water indicates the specimen contains surface-connected porosity. Unsealed surface porosity will absorb water and cause density values higher than the true value. If this problem occurs, this method is not applicable and Standard 42 should be used instead.
With the exception of density, for which g/cm3 is the industry standard, SI units are used in this standard. Values in inch-pound units are shown in parentheses and result from conversion in accordance with IEEE/ASTM Standard SI 10. They may be approximate and are only for information.
This standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the potential safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
