Methods of test for petroleum and its products. Determination of demulsibility characteristics of lubricating oil (Identical with IP 19/11) | Status: Confirmed, Current

1 Scope 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.

NOTE 1 Oils containing inhibitors may give much higher results than the corresponding uninhibited oils and the precision may be less satisfactory.

NOTE 2 For the purposes of this standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
