MICRO LUBRICANT TEST METHODS Part IV. Evaporation Loss of Lubricating Greases and Oils, Viscosity of Lubricants at —65°F, and Foaming Characteristics of Crankcase and Aircraft Engine Lubricating Oils

摘要

This report describes test methods for the determination of evaporation loss of lubricating greases and oils, viscosity of lubricants at -65℉., and the foaming characteristics of crankcase and aircraft engine lubricating oils. All procedures were arrived at through the comparison of the micro test results with results obtained through the use of existing test procedures.
