scope:

This standard describes a test that determines the compressibility of metal powders by measuring the green density of a test specimen resulting from subjecting metal powder to a uniaxial compressive loading in a confining die.

Compressibility may be determined by using either of the following specimens:

Specimen A: Using a cylindrical die to produce a specimen 1 inch (25.4 mm) in diameter.

Specimen B: Using the standard rectangular transverse rupture die to produce a specimen 1.25 by 0.50 inches (31.8 by 12.7 mm).

With the exception of density, for which g/cm³ is the industry standard, this standard uses inch-pound units. Values in SI 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.
