ASHRAE STD 172
Method of Test for Insoluble Materials in Synthetic Lubricants and HFC Refrigerant Systems
|Publication Date:||31 March 2017|
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/refrigeran
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.
