scope:

This standard describes a method for measuring the surface finish of powder metallurgy products at all stages of manufacturing, from green compact to fully hardened.

This method filters out the influence of open surface porosity on surface finish.

The values stated in inch-pound units are to be regarded as the standard. 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.
