Standard Test Methods for Oil Content, Oil-Impregnation Efficiency, and Surface-Connected Porosity of Sintered Powder Metallurgy (PM) Products Using Archimedes’ Principle

Importancia y uso:

5.1 Oil content values are generally contained in specifications for oil-impregnated PM bearings.

5.2 The oil-impregnation efficiency provides an indication of how well the as-received parts had been impregnated.

5.3 The desired self-lubricating performance of PM bearings requires a minimum amount of surface-connected porosity and satisfactory oil impregnation of the surface-connected porosity. A minimum oil content is specified.

5.4 The results from these test methods may be used for quality control or compliance purposes.
