Standard Test Methods for Oil Content, Oil-Impregnation Efficiency, and Interconnected Porosity of Sintered Powder Metallurgy (PM) Products Using Archimedes’ Principle
|Publication Date:||1 April 2013|
|ICS Code (Powder metallurgy):||77.160|
This standard describes three related test methods that cover the measurement of physical properties of oilimpregnated powder metallurgy products.
Determination of the volume percent of oil contained in the material.
Determination of the efficiency of the oilimpregnation process.
Determination of the percent interconnected porosity by oil impregnation.
With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm3) and gram (g) units is the longstanding industry practice, the values in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
