IP 19 DETERMINATION OF DEMULSIBILITY CHARACTERISTICS OF LUBRICATING OILSThis method gives a measure of the ability of the oil to separate from an emulsion. It is commonly applied to turbine oils, but it may be used for other lubricating oils. The test is commonly applied to used turbine oils but since it is sensitive to aging and contamination of the oil, precision will be lower than that stated.
