ASTM D91 - Precipitation Number of Lubricating Oils: This test method determines the precipitation number of steam cylinder stocks and black oils, which 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 D483 - Standard Test Method for Unsulfonated Residue of Petroleum Plant Spray Oils: This test method covers the determination of sulfonated residue in plant spray oils of petroleum origin and applies only to the petroleum oil content.
ASTM D893 - Insolubles in Used Lubricating Oils: This test method covers the determination of pentane and toluene insoluble in used lubricating oils.
ASTM D1290 - Sediment in Water-emulsion Polishes: This test method uses a centrifuge to determine sediment in water-emulsion polishes.
ASTM D1093 - Standard Practice for Accreditation of Testing Agencies for Masonry: This practice provides the bare minimum criteria for evaluating the qualifications of testing agencies for masonry materials.
