Determination of Water in Petroleum Products (ASTM D95)

Water Saturation

This test method covers the determination of water in petroleum products by the distillation method. The sample is heated under reflux with a water-immiscible solvent (using Dean-Stark apparatus). The mixture of core’s water and solvents’ vapors is evaporated by distillation and further condensed in a suitable volumetric tube, where water is separated gravimetrically and quantitatively determined.
