scope:

This standard describes a method for measuring the Oil Content, Surface-Connected Porosity and Oil-Impregnation Efficiency of powder metallurgy (PM) products having Surface-Connected Porosity.

Oil Content as received (P₁), is the percentage of oil by volume of a sintered PM part.

Surface-Connected Porosity (P), is the percentage of surface-connected porosity by volume of a sintered PM part determined by the amount of oil impregnation.

NOTE 1-The Surface-Connected Porosity (P) is the same as the fully impregnated oil content (P).

Oil-Impregnation Efficiency (I_E), is calculated by dividing the as-received oil content (P₁), by the fully impregnated oil content (P), and expressing the result as a percentage.

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