  • DISTILLATION OF PETROLEUM PRODUCTS: ASTM D86 DISTILLATION OF PETROLEUM PRODUCTS: ASTM D86(Equivalent Test Methods: IP 123, ISO 3405, DIN 51751, JIS K 2254, and AFNOR M07-002)EXPLANATIONDistillation (volatility) properties of petroleum products are indicative of their performance. The empirical results obtained by this test method have been found ...
  • DISTILLATION OF HEAVY HYDROCARBON MIXTURES: ASTM D5236 DISTILLATION OF HEAVY HYDROCARBON MIXTURES: ASTM D5236EXPLANATIONThis is a complex procedure involving many interacting variables. It is most important that at the time of first use of a new apparatus, its components be checked in detail as described in the method. This method describes a procedure for ...
  • DISTILLATION OF CRUDE PETROLEUM: ASTM D2892 DISTILLATION OF CRUDE PETROLEUM: ASTM D2892(Equivalent Test Method: ISO 8708)GENERALThis test provides an estimate of the yields of fractions of various boiling ranges, and is therefore valuable in technical discussions of a commercial nature. This test method corresponds to the standard laboratory distillation ...
  • DISTILLATION OF PETROLEUM PRODUCTS DISTILLATION OF PETROLEUM PRODUCTSGENERALThe basic method of distillation to determine the boiling range of a petroleum product has been in use since the beginning of the petroleum industry. Distillation method, Test Method ASTM D86 is one of the oldest methods under the jurisdiction of ASTM D02 Committee. ...
  • DIESEL FUEL DILUENT IN USED DIESEL ENGINE OILS BY GAS CHROMATOGRAPHY: ASTM D3524 DIESEL FUEL DILUENT IN USED DIESEL ENGINE OILS BY GAS CHROMATOGRAPHY: ASTM D3524EXPLANATIONSome fuel dilution of the engine oil may take place during normal operations. However, excessive fuel dilution is of concern in terms of possible performance problems. This test method covers the determination ...
  • DEPENTANIZATION OF GASOLINE AND NAPTHAS: ASTM D2001 DEPENTANIZATION OF GASOLINE AND NAPTHAS: ASTM D2001EXPLANATIONThe presence of pentane and lighter hydrocarbons in gasolines, napthas, and similar petroleum distillates interferes in the determination of hydrocarbon types by Test Methods ASTM D1319 and ASTM D2789. Pentane and lighter hydrocarbons are ...
  • DENSITY AND RELATIVE DENSITY OF VISCOUSMATERIALS BY LIPKIN PYCNOMETER: ASTM D148 DENSITY AND RELATIVE DENSITY OF VISCOUSMATERIALS BY LIPKIN PYCNOMETER: ASTM D1481EXPLANATIONThis test method is applicable to oils more viscous than 15 cSt at 20° C, and of viscous oils and melted waxes at elevated temperatures, but not at temperatures at which the sample would have a vapor pressure ...
  • DENSITY AND RELATIVE DENSITY OF VISCOUS MATERIALS BY BINGHAM PYCNOMETER: ASTM D1 DENSITY AND RELATIVE DENSITY OF VISCOUS MATERIALS BY BINGHAM PYCNOMETER: ASTM D1480EXPLANATIONThis test method is applicable to liquids of vapor pressures below 600 mm Hg 80 kPa and viscosities below 40 000 cSt at the test temperature. This test method can be used at temperatures between 20 and 100° ...
  • DENSITY, RELATIVE DENSITY AND API GRAVITY BY THERMOHYDROMETER METHOD: ASTM D6822 DENSITY, RELATIVE DENSITY AND API GRAVITY BY THERMOHYDROMETER METHOD: ASTM D6822EXPLANATIONDensity and API gravity are used in custody transfer quantity calculations and to satisfy transportation, storage, and regulatory requirements. These are also the factors that indicate the quality of crude petroleum. ...
  • DYNAMIC VISCOSITY AND DENSITY BY STABINGER VISCOMETER: ASTM D7042 DYNAMIC VISCOSITY AND DENSITY BY STABINGER VISCOMETER: ASTM D7042EXPLANATIONDensity and viscosity are important properties of petroleum and nonpetroleum liquids. This test method provides concurrent measurements of both dynamic viscosity and density of liquid petroleum products and crude oils. The kinematic ...
