ASTM D1796 Water and Sediment in Fuel Oils by Centrifuge Method (Laboratory Procedure)
Sediment and water in fuel oils may cause processing problems, accelerate corrosion and clog filters. This method determines the percent (from 0 to 30%) of water and sediment in fuel oils. It may not be appropriate for samples containing alcohols. The sample is placed in a centrifuge tube, diluted with toluene, and spun until a constant volume of water + sediment is obtained. The volume percent is reported.
