适用范围：This method of test describes a procedure for the measurement of the ability of petroleum oils or synthetic fluids to separate from water.Noth 1 —Although developed specifically for steam-turbine oils having visco-sities of 32 to 97 cSt at 38°C, this method may be used to test oils of other types having various viscosities and synthetic fluids. It is recommended, however, that the test temperature be raised to 82 ± 1℃ when testing products more viscous than 97 cSt.Note 2 — Other test temperatures such as 25°C may also be used.Note 3 — When testing synthetic fluids whose relative densities are greater than that of water, the procedure is unchanged, but it should be noted that the water will probably float on the emulsion or liquid.
