  • REFRACTIVE INDEX OF VISCOUS MATERIALS: D1747 REFRACTIVE INDEX OF VISCOUS MATERIALS: D1747EXPLANATIONRefractive index is a fundamental physical property that can be used in conjunction with other properties to characterize pure hydrocarbons and their mixtures. The use of refractive index in correlative methods for the determination of the gross ...
  • REFRACTIVE INDEX OF HYDROCARBON LIQUIDS: D1218 REFRACTIVE INDEX OF HYDROCARBON LIQUIDS: D1218(Equivalent Test Methods: ISO 5661 and DIN 51423 T2)EXPLANATIONRefractive index and refractive dispersion are fundamental physical properties which can be used in conjunction with other properties to characterize pure hydrocarbons and their mixtures. This ...
  • RED DYE CONCENTRATION AND ESTIMATION OF SAYBOLT COLOR OF AVIATION TURBINE FUELS RED DYE CONCENTRATION AND ESTIMATION OF SAYBOLT COLOR OF AVIATION TURBINE FUELS AND KEROSENE: D7058EXPLANATIONIn the United States, high-sulfur content distillate products and diesel fuel used for off-road purposes, other than aviation turbine fuel are required to contain red dye. A similar dye requirement ...
  • RED DYE CONCENTRATION AND ESTIMATION OF ASTM COLOR OF DIESEL FUEL AND HEATING OI RED DYE CONCENTRATION AND ESTIMATION OF ASTM COLOR OF DIESEL FUEL AND HEATING OIL: D6756EXPLANATIONIn the United States, high sulfur content (as defined by the U.S. Environmental Protection Agency) middle distillate products and diesel fuel used for off-road purposes, other than aviation turbine fuels, ...
  • RAMSBOTTOM CARBON RESIDUE: D524 RAMSBOTTOM CARBON RESIDUE: D524(Equivalent Test Methods: IP 14, ISO 4262, and AFNOR T60-117)EXPLANATIONThe carbon residue value of burner fuel serves as a rough approximation of the tendency of the fuel to form deposits in vaporizing pot- and sleeve-type burners. Similarly, provided alkyl nitrates are ...
  • QUINOLINE INSOLUBLE IN TAR AND PITCH BY PRESSURE FILTRATION: D4746 QUINOLINE INSOLUBLE IN TAR AND PITCH BY PRESSURE FILTRATION: D4746EXPLANATIONThis test method is useful in evaluating and characterizing tar and pitch, and as one element in establishing the uniformity of shipments and sources of supply. Since this method is empirical, strict adherence to all details ...
  • QUINOLINE INSOLUBLE CONTENT OF TAR AND PITCH: D2318 QUINOLINE INSOLUBLE CONTENT OF TAR AND PITCH: D2318EXPLANATIONThis test method is useful in evaluating and characterizing tar and pitch, and as one element in establishing the uniformity of shipments and sources of supply. Since this method is empirical, strict adherence to all details of the procedure ...
  • QUENCHING TIME OF HEAT TREATING FLUIDS: D3520 QUENCHING TIME OF HEAT TREATING FLUIDS: D3520EXPLANATIONThis method covers a procedure for making a comparative evaluation of the quenching speed characteristics of petroleum fluids used in quenching of metals by means of the magnetic quenchometer. A comparison method for evaluation of the quenching ...
  • PUMPABILITY OF INDUSTRIAL FUEL OILS: D3245 PUMPABILITY OF INDUSTRIAL FUEL OILS: D3245EXPLANATIONThis test method is designed to give an indication of the minimum storage and minimum handling temperatures, which may be used for a given fuel oil. This test method is cited in Specification D396.TEST SUMMARYA sample of oil, preheated if necessary ...
  • PRECIPITATION NUMBER OF LUBRICATING OILS: D91 PRECIPITATION NUMBER OF LUBRICATING OILS: D91EXPLANATIONFully refined petroleum oils normally contain no naptha insoluble material. Semirefined or black oils frequently contain some naptha insoluble material, sometimes referred to as asphaltenes. This test measures the amount of naptha insoluble material ...
