  • WATER IN PETROLEUM PRODUCTS AND LUBRICANTS BY COULOMETRIC KARL FISCHER TITRATION WATER IN PETROLEUM PRODUCTS AND LUBRICANTS BY COULOMETRIC KARL FISCHER TITRATION: D6304TEST SUMMARYThis test method covers the direct determination of water in the range of 10 to 25 000 mg/kg entrained water in petroleum products and hydrocarbons using automated instrument. This test method is applicable ...
  • FREE WATER IN MID-DISTILLATE FUELS: D4860 FREE WATER IN MID-DISTILLATE FUELS: D4860TEST SUMMARYThis test is similar to D4176 just described. The color of sample does not affect the measurement. The test uses a rapid, portable means of visually inspecting for particulate matter and rating numerically for free water in aviation turbine and distillate ...
  • FREE WATER IN DISTILLATE FUELS: D4176 FREE WATER IN DISTILLATE FUELS: D4176TEST SUMMARYFuel specifications often contain the requirement that it be clear and bright and free of visible particulate matter. This test method provides two procedures to cover that requirement. This test method is applicable to distillate fuels having distillation ...
  • FREE WATER, PARTICULATES, AND CONTAMINANTS IN AVIATION FUELS: D6986 FREE WATER, PARTICULATES, AND CONTAMINANTS IN AVIATION FUELS: D6986EXPLANATIONFuel quality is paramount in aviation fuels because of their critical application. Many successive types of inspections are conducted to ensure quality protection. Rapid, visual inspections carried out at various locations ...
  • WATER IN CRUDE OILS BY POTENTIOMETRIC KF TITRATION: D4377 WATER IN CRUDE OILS BY POTENTIOMETRIC KF TITRATION: D4377(Equivalent Test Method: IP 356)TEST SUMMARYThis test method covers the determination of 0.02 to 2 % in crude oil. Mercaptan and sulfide interfere. At levels <500 ppm as sulfur their interference is insignificant. After homogenizing the crude ...
  • WATER IN CRUDE OIL BY DISTILLATION: D4006 WATER IN CRUDE OIL BY DISTILLATION: D4006(Equivalent Test Method: IP 358)TEST SUMMARYThe sample is heated under reflux conditions with a water immiscible solvent (xylene), which co-distills with the water in the sample. Condensed solvent and water are continuously separated in a trap; the water settles ...
  • WATER IN CRUDE OILS BY COULOMETRIC KF TITRATION: D4928 WATER IN CRUDE OILS BY COULOMETRIC KF TITRATION: D4928(Equivalent Test Methods: IP 386 and ISO 10337)TEST SUMMARYThis test method is applicable to the determination of water in the range 0.02 to 5 mass % in crude oils. Mercaptan and sulfide interfere. At levels of <500 ppm as sulfur, the interference ...
  • WATER IN PETROLEUM PRODUCTS WATER IN PETROLEUM PRODUCTSGENERALA knowledge of the water content of petroleum products is important in refining, purchase and sale, and transfer of products, and is useful in predicting the quality and performance characteristics of the products.There are numerous methods for the determination of water ...
  • VOLATILITY OF LPG: D1837 VOLATILITY OF LPG: D1837EXPLANATIONVolatility, expressed in terms of the 95 % evaporated temperature of the product, is a measure of the amount of least volatile components present in the product. Coupled with a vapor pressure limit, it serves to ensure essentially single-component products in the cases ...
  • PITCH VOLATILITY: D4893 PITCH VOLATILITY: D4893EXPLANATIONThis test is useful in evaluating and characterizing pitch physical properties in comparing the consistency of shipments of sources of supply. Since this test method is empirical, strict adherence of the procedure is necessary.TEST SUMMARYAn aluminum weighing dish with ...
