1.1 This standard describes three related test methods that cover the measurement of physical properties of oil-impregnated powder metallurgy products.
1.1.1 Determination of the volume percent of oil contained in the material.
1.1.2 Determination of the efficiency of the oil-impregnation process.
1.1.3 Determination of the percent interconnected porosity by oil impregnation.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are converted in accordance with IEEE/ASTM SI 10 and are for information only.
1.3 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.
