scope:

This standard covers the apparatus, test specimen and procedures for determining the bending strength or transverse rupture strength of powder metallurgy materials.

The test as described and specified herein is applicable only to materials of negligible ductility. If applied to materials showing noticeable plastic deformation (exceeds 0.02 inch [0.5 mm]) permanent deflection, the maximum load may not be equal to the break load, which could lead to misinterpretation of results. For such materials the tensile strength test should be used.

With the exception of density, for which g/cm3 is the industry standard, this standard uses inch-pound units. Value in SI units are shown in parentheses and result from conversion in accordance with IEEE/ASTM 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.
