  • 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 ...
  • VOLATILE MATTER IN PETROLEUM COKE: D4421 VOLATILE MATTER IN PETROLEUM COKE: D4421EXPLANATIONThe volatile matter in petroleum coke affects the density of coke particles and can affect artifacts produced from further processing of the coke. The volatile matter can be used in estimating the calorific value of coke. Samples having a thermal history ...
  • VOLATILE MATTER IN GREEN PETROLEUM COKE: D6374 VOLATILE MATTER IN GREEN PETROLEUM COKE: D6374EXPLANATIONThe volatile matter of petroleum coke affects the density of coke particles and can affect artifacts produced from further processing of the coke. The volatile matter can be used in estimating the calorific value of coke. This test method covers ...
  • VOLATILES CONTAMINANTS IN USED ENGINE OILS: D3607 VOLATILES CONTAMINANTS IN USED ENGINE OILS: D3607EXPLANATIONThe removal of volatile materials such as gasoline dilution from used engine oils is especially important if the mechanical shear stability or oxidative stability of the oil is being monitored by measuring a kinematic viscosity change in the ...
  • VISCOSITY-TEMPERATURE RELATIONSHIP OF USED AND SOOT CONTAINING ENGINE OILS: D711 VISCOSITY-TEMPERATURE RELATIONSHIP OF USED AND SOOT CONTAINING ENGINE OILS: D7110EXPLANATIONThe low temperature, low shear viscometric behavior of an engine oil, whether new, used, or sooted, determines whether the oil will flow to the sump inlet screen, then to the oil pump, then to the sites in the ...
  • VISCOSITY, SHEAR OF COAL-TAR AND PETROLEUM PITCHES: D5018 VISCOSITY, SHEAR OF COAL-TAR AND PETROLEUM PITCHES: D5018EXPLANATIONThis test method is useful as one element in establishing the uniformity of shipments. Viscosity is valuable for rheological characterization of binder pitches. Binder pitch imparts consistency to carbonaceous mixes and affects their ...
  • SAYBOLT UNIVERSAL VISCOSITY: D2161 SAYBOLT UNIVERSAL VISCOSITY: D2161EXPLANATIONThis practice covers the conversion tables and equations for converting kinematic viscosity in centistokes (cSt) at any temperature to Saybolt Universal viscosity in Saybolt Universal seconds (SUS) at the same temperature and for converting kinematic viscosity ...
  • ROTATIONAL VISCOSITY OF HEAVY DUTY DIESEL DRAIN OILS AT 100° C: D6895 ROTATIONAL VISCOSITY OF HEAVY DUTY DIESEL DRAIN OILS AT 100° C: D6895EXPLANATIONRotational viscosity measurements allow the determination of the non-Newtonian, shear thinning property of drain oil. Rotational viscosity values can be compared at a shear rate of 100 s(-1) by this test method. This test ...
