ASTM D1401 ISO 6614 DIN 51599 (obs) WATER SEPARABILITY OF PETROLEUM OILS AND SYNTHETIC FLUIDS
This test method covers measurement of the ability of petroleum oils or synthetic fluids to separate from water. Although developed
specifically for steam-turbine oils having viscosities of 28.890 mm2/s at 40C, this test method may be used to test oils of
other types having various viscosities and synthetic fluids at other test temperatures. It is recommended, however, that the test
temperature be raised to 82 1C when testing products more viscous than 90 mm2/s at 40C. For higher viscosity oils where
there is insufficient mixing of oil and water, Test Method D2711 is recommended.

This Herschel test apparatus has a structure with 3 independent positions and rear illumination, stainless steel heater controlled by a digital thermoregulator PID and probe PT100A, overtemperature alarm, 3x independent variable stirrer motor and is lowered and raised automatically. The Herschel test apparatus includes 3x programmable digital timers for duration of the test, motor stirrer for bath, variable speed controller 150 to 1999 rpm, stainless steel blade agitator 19ױ.5mm L=120 mm connected to a stainless steel 6 mm shaft. Max temperature 150C
