Scope
This standard specifies the method for determining the density of dense sintered metal materials and hard alloys. Note: For the determination of the density of permeable sintered metal materials, refer to ISO 2738:1999, which specifies the determination of the density, oil content, and porosity of permeable sintered metal materials (excluding hard alloys).
