【摘要】: Oil content values are generally contained in specifications for oil-impregnated PM bearings. The oil-impregnation efficiency provides an indication of how well the as-received parts had been impregnated. The desired self-lubricating performance of PM bearings requires a minimum amount of interconnected porosity and satisfactory oil impregnation of the interconnected porosity. A minimum oil content is specified. The results from these test methods may be used for quality control or compliance purposes.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.
