ASHRAE STD 86
Methods of Testing the Floc Point of Refrigeration-Grade Oil
|Publication Date:||2 January 2013|
The floc point measurement indicates the waxing tendency of refrigeration-grade oils at low temperatures. The floc point is defined as the highest temperature at which wax or other solid substances precipitate when a mixture 10% by volume of oil and 90% by volume of R-12 is cooled under specified conditions. The results can be used to compare the waxing tendency of several different oils.
This standard provides a method for measuring the waxing tendency of refrigeration-grade oils.
