  • PISTON DEPOSITS BY TEOST MHT: D7097 PISTON DEPOSITS BY TEOST MHT: D7097EXPLANATIONThis test method is designed to predict the deposit-forming tendencies of engine oils in the piston ring belt and upper piston crown area. Correlation has been shown between the TEOST MHT procedure and the TU3MH Peugot engine test in deposit formation. Such ...
  • PHOSPHORUS DETERMINATION IN LUBRICATING OILS: D4047 PHOSPHORUS DETERMINATION IN LUBRICATING OILS: D4047(Equivalent Test Methods: IP 149 and ISO 4265)TEST SUMMARYThis test method is applicable in the range 0.005 to 10.0 mass % of phosphorus in unused lubricating oils and additive concentrates. It should be applicable to filtered used oils also; but no ...
  • PHOSPHORUS DETERMINATION IN LUBRICATING OILS: D1091 PHOSPHORUS DETERMINATION IN LUBRICATING OILS: D1091TEST SUMMARYOrganic material in the sample is destroyed and phosphorus in the sample is converted to phosphate ion by oxidation with sulfuric acid+ nitric acid+ hydrogen peroxide. When the phosphorus content is <2 %, the molybdovanado photometric ...
  • PHOSPHORUS DETERMINATION IN GASOLINE: D3231 PHOSPHORUS DETERMINATION IN GASOLINE: D3231TEST SUMMARYThis test method is applicable for the determination of phosphorus in the range from 0.2 to 40 mg/L. Organic matter in the sample is decomposed by ignition in the presence of zinc oxide. The residue is dissolved in sulfuric acid and reacted with ...
  • PHOSPHORUS DETERMINATION IN PETROLEUM PRODUCTS PHOSPHORUS DETERMINATION IN PETROLEUM PRODUCTSGENERALDepending upon the product, phosphorus can serve as a beneficial adjunct or as a deleterious agent. Phosphorus in gasoline will damage catalytic converters used in automotive emission control systems, and its level therefore is kept low. In additives ...
  • PETROLEUM WAX ANALYSIS BY GC: D5442 PETROLEUM WAX ANALYSIS BY GC: D5442EXPLANATIONThe determination of carbon number distribution of petroleum waxes and the normal and nonnormal hydrocarbons in each can be used for controlling the production processes as well as a guide to performance in many end users, particularly in rubber formulations. ...
  • PEROXIDE NUMBER OF PETROLEUM WAX: D1832 PEROXIDE NUMBER OF PETROLEUM WAX: D1832EXPLANATIONDeterioration of petroleum wax results in the formation of peroxides and other oxygen-containing compounds. The peroxide number measures those compounds that will oxidize potassium iodide. Thus the magnitude of the peroxide number is an indication of ...
  • PEROXIDE NUMBER OF AVIATION TURBINE FUELS: D3703 PEROXIDE NUMBER OF AVIATION TURBINE FUELS: D3703EXPLANATIONThe magnitude of the peroxide number is an indication of the quantity of oxidizing constituents present in the sample. Deterioration of turbine fuel results in the formation of the peroxides and other oxygen-carrying compounds. The peroxide number ...
  • POLYCHLORINATED BIPHENYLS (PCBs) IN WASTES BY GAS CHROMATOGRAPHY: D6160 POLYCHLORINATED BIPHENYLS (PCBs) IN WASTES BY GAS CHROMATOGRAPHY: D6160EXPLANATIONThis test method provides sufficient PCB data for many regulatory requirements. While the most common regulatory level is 50 ppm, lower limits are used in some locations. This test method uses a two-tiered analytical approach ...
  • PEROXIDES IN BUTADIENE: D5799 PEROXIDES IN BUTADIENE: D5799EXPLANATIONDue to inherent danger of peroxides in butadiene, specification limits are usually set for their presence. Butadiene polyperoxide is a very dangerous product of the reaction between butadiene and oxygen that can occur. The peroxide has been reported to be the cause ...
