scope:
This method covers the apparatus, test specimens and procedure for determining the green strength of compacted powder metallurgy specimens by subjecting them to a uniformly increasing transverse loading under controlled conditions. The green strength, as used in this standard, is the stress, calculated from the flexure formula, required to break the powder metallurgy compact as a simple beam. The specimen is supported near the ends, and broken by applying the force midway between the fixed center of the supports.
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.
