Standard Test Methods for Oil Content, Oil-Impregnation Efficiency, and Surface-Connected Porosity of Sintered Powder Metallurgy (PM) Products Using Archimedes” Principle
ASTM International , 04/01/2017
Pages: 6
1.1This standard describes three related test methods that cover the measurement of physical properties of oil-impregnated powder metallurgy products.
1.1.1Determination of the volume percent of oil contained in the material.
1.1.2Determination of the efficiency of the oil-impregnation process.
1.1.3Determination of the percent surface-connected porosity by oil impregnation.
1.2With 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 long-standing 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.
1.3This 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.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
