Method of Test for Insoluble Materials in Lubricants and Refrigerant Systems
Defines a test method to determine the formation of insoluble materials in lubricant and refrigerant systems. The test will determine the presence of materials that separate from refrigerant and lubricant mixtures over a range of temperatures and concentrations. The test is based on the precipitation of insoluble material in a lubricant/refrigerant combination. The results can be used to compare lubricants and refrigerants. Dual units of measurement.
