  • OXYGENATES O-PONA HYDROCARBONS IN FUELS BY GC: D6293 OXYGENATES O-PONA HYDROCARBONS IN FUELS BY GC: D6293EXPLANATIONA knowledge of spark-ignition engine fuel composition is useful for regulatory compliance, process control, and quality assurance. This test method provides for the quantitative determination of oxygenates, paraffins, olefins, napthenes, ...
  • OXYGENATES IN GASOLINE BY GAS CHROMATOGRAPHY: D5599 OXYGENATES IN GASOLINE BY GAS CHROMATOGRAPHY: D5599(Equivalent Test Method: IP 408)EXPLANATIONAlcohols, ethers, and other oxygenates are added to gasoline to increase the octane number and to reduce tailpipe emission of carbon monoxide. They must be added in the proper concentration and ratios to meet ...
  • OXYGEN IN GASOLINE AND FUELS BY REDUCTIVE PYROLYSIS: D5622 OXYGEN IN GASOLINE AND FUELS BY REDUCTIVE PYROLYSIS: D5622EXPLANATIONThe presence of oxygen-containing compounds in gasoline can promote more complete combustion which reduces carbon monoxide emissions. The Clean Air Act of 1992 requires that gasoline sold within certain, specified geographical areas ...
  • OXIDATION STABILITY OF STEAM TURBINE OILS BY ROTATING PRESSURE VESSEL: D2272 OXIDATION STABILITY OF STEAM TURBINE OILS BY ROTATING PRESSURE VESSEL: D2272EXPLANATIONThe estimate of oxidation stability is useful in controlling the continuity of this property for batch acceptance of production lots having the same operation. This test method utilizes an oxygen pressured vessel to ...
  • OXIDATION STABILITY OF OILS BY UNIVERSAL OXIDATION TEST: D5846 OXIDATION STABILITY OF OILS BY UNIVERSAL OXIDATION TEST: D5846EXPLANATIONDegradation of hydraulic fluids and turbine oils, because of oxidation or thermal breakdown, can result in the formation of acids or insoluble solids and render the oil unfit for further use. This test method covers a procedure ...
  • OXIDATION STABILITY OF LUBRICATING GREASES: D942 OXIDATION STABILITY OF LUBRICATING GREASES: D942(Equivalent Test Methods: IP 142 and DIN 51808)EXPLANATIONThis test method measures the net change in pressure resulting from oxygen consumption by oxidation and gain in pressure due to the formation of volatile oxidation by-products. This test method does ...
  • OXIDATION STABILITY OF INHIBITED MINERAL OILS: D943 OXIDATION STABILITY OF INHIBITED MINERAL OILS: D943(Equivalent Test Method: ISO 4263)EXPLANATIONThis test method is widely used for specification purposes and is considered of value when estimating the oxidation stability of lubricants, especially those that are prone to water contamination. However, ...
  • OXIDATION STABILITY OF GEAR OILS: D5763 OXIDATION STABILITY OF GEAR OILS: D5763EXPLANATIONDegradation of gear oils by oxidation or thermal breakdown, or both, can result in sludge buildup and render the oil unsuitable for further use as a lubricant. This test method covers the determination of the oxidation characteristics of extreme pressure ...
  • OXIDATION STABILITY OF GASOLINE: D525 OXIDATION STABILITY OF GASOLINE: D525(Equivalent Test Methods: IP 40, ISO 7536, DIN 51780, and AFNOR M07-012)EXPLANATIONThe induction period may be used as an indication of the tendency of motor gasoline to form gum in storage. However, its correlation with the formation of gum in storage may vary markedly ...
  • OXIDATION STABILITY OF EXTREME PRESSURE LUBRICATING OILS: D2893 OXIDATION STABILITY OF EXTREME PRESSURE LUBRICATING OILS: D2893EXPLANATIONThis test method has been widely used to measure the oxidation stability of extreme pressure lubricating fluids, gear oils, and mineral oils. The changes in the lubricant resulting from this test method are not always associated ...
