Scope

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 efrigerant combination. The results can be used to compare lubricants and refrigerants. PURPOSE The purpose of this standard is to define a test method to determine the formation of insoluble materials in synthetic lubricants and hydrofluorocarbon (HFC) systems.
