ASTM D91 - Precipitation Number of Lubricating Oils
This test method covers the determination of the precipitation number of steam cylinder stocks and black oils, and can be used for other lubricating oils.

ASTM D96 (obs.) - Water and Sediment In Crude Oil
This test method covers the centrifuge method for determining sediment and water in crude oil during field custody transfers.

ASTM D893 - Insolubles in Used Lubricating Oils
This test method covers the determination of pentane and toluene insoluble in used lubricating oils.

ASTM D1796 - Water and Sediment in Fuel Oils
This test method covers the laboratory test for determination of water and sediment in fuel oils by using the centrifuge method in the range from 0 to 30 % volume.

ASTM D2273 - Trace Sediment in Lubricating Oils
This test method covers the determination of trace amounts (less than 0.05 volume %) of sediment in lubricating oils.

ASTM D2709 - Water And Sediment in Middle Distillate Fuels
This test method covers the determination of the volume of free water and sediment in middle distillate fuels having viscosities at 40°C (104°F) in the range of 1.0 to 4.1 mm/s (1.0 to 4.1 cSt) and densities in the range of 770 to 900 kg/m.

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.

ASTM D4007 - Water and Sediment in Crude Oil
This test method describes the laboratory determination of water and sediment in crude oils by means of the centrifuge procedure.

ASTM D5546 - Standard Test Method for Solubility of Asphalt Binders in Toluene by Centrifuge.
This test method covers determination of the degree of solubility of asphalt binders in toluene using centrifugal separation. The method is an alternative to Test Method D 2042, and may be preferable to Test Method D 2042 when testing modified asphalt binders.
