Demulsibility

ASTM D2711 DEMULSIBILITY CHARACTERISTICS OF LUBRICATING OILS
This test method covers the measurement of the ability of oil and water to separate from each other. It is intended for use in testing medium and high-viscosity lubricating oils.

IP 19 DETERMINATION OF DEMULSIBILITY CHARACTERISTICS OF LUBRICATING OILS
This 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.

DEMULSIBILITY APPARATUS

Consisting of: a steam generator including: 1 electric-heater units with electronic-power regulators, 1 support boards with ceramic plate with an hole Ø 51 mm, 1 steam generator flask capacity:1 litre, 1 stopper for flask, 1 ventilation tube, 2 steam pipings, 1 hose connection of 2 m, 3 clamps for hose, 1 support rod, 1 boss head, 1 clamp.
An Emulsifying Bath including: 1 tripod stand: Ø 100 mm, 1 support boards made of ceramic glass, 1 glass jar as bath of 3000 ml, 1 cover for bath with stopper, 1 oil test tube made of glass, 1 stopper for oil test tube, 1 steam inlet tube. A Separating Bath including: 1 electric-heater units with electronic- power regulators, 1 support boards made of cast iron, 1 glass jar of 3000 ml as bath, 1 cover for bath with stopper, 1 steam inlet tube.
