  • PEROXIDES IN BUTADIENE: ASTM D5799 PEROXIDES IN BUTADIENE: ASTM 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 ...
  • PARTICULATE CONTAMINATION IN MIDDLE DISTILLATE FUELS: ASTM D6217 PARTICULATE CONTAMINATION IN MIDDLE DISTILLATE FUELS: ASTM D6217(Equivalent Test Methods: IP 415 and ISO 15167)EXPLANATIONThe mass of particulates present in a fuel is a significant factor, along with size and the nature of the individual particles, in the rapidity with which the fuel filters and other ...
  • PARTICULATE CONTAMINATION IN AVIATION FUEL: ASTM D2276 PARTICULATE CONTAMINATION IN AVIATION FUEL: ASTM D2276(Equivalent Test Method: IP 216)EXPLANATIONThis test method uses a field monitor. Two methods are described. One measures gravimetrically. The other uses a color rating technique for rapid qualitative assessment of changes in contaminant level without ...
  • PARTICULATE CONTAMINATION IN AVIATION FUELS: ASTM D5452 PARTICULATE CONTAMINATION IN AVIATION FUELS: ASTM D5452EXPLANATIONThis test method provides a gravimetric measurement of the particulate matter present in a sample of aviation turbine fuel. The objective is to minimize these contaminants to avoid filter plugging and other operational problems. Although ...
  • OXYGENATES O-PONA HYDROCARBONS IN FUELS BY GC: ASTM D6293 OXYGENATES O-PONA HYDROCARBONS IN FUELS BY GC: ASTM 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: ASTM D5599 OXYGENATES IN GASOLINE BY GAS CHROMATOGRAPHY: ASTM 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 ...
  • OXYGEN IN GASOLINE AND FUELS BY REDUCTIVE PYROLYSIS: ASTM D5622 OXYGEN IN GASOLINE AND FUELS BY REDUCTIVE PYROLYSIS: ASTM 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 ...
  • OXIDATION STABILITY OF STEAM TURBINE OILS BY ROTATING PRESSURE VESSEL: ASTM D227 OXIDATION STABILITY OF STEAM TURBINE OILS BY ROTATING PRESSURE VESSEL: ASTM 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 ...
  • OXIDATION STABILITY OF OILS BY UNIVERSAL OXIDATION TEST: ASTM D5846 OXIDATION STABILITY OF OILS BY UNIVERSAL OXIDATION TEST: ASTM 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: ASTM D942 OXIDATION STABILITY OF LUBRICATING GREASES: ASTM 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 byproducts. This test method ...
