Standard 172 defines a test method to determine the formation of insoluble materials in lubricant and refrigerant systems. The test determines the presence of materials that separate from refrigerant and lubricant mixtures over a range of temperatures and concentrations and is based on the precipitation of insoluble material in a lubricant/refrigerant combination. The results can be used to compare lubricants and refrigerants.
