  • TRACE METALS IN GAS TURBINE FUELS BY AA/FES: D3605 TRACE METALS IN GAS TURBINE FUELS BY AA/FES: D3605(Equivalent Test Methods: IP 413, ISO 8691, and DIN 51790 T3)EXPLANATIONKnowledge of the presence of trace metals in gas turbine fuels enables the user to predict performance and, when necessary, to take appropriate action to prevent corrosion. This test ...
  • METAL ANALYSIS BY SPECTROSCOPY METAL ANALYSIS BY SPECTROSCOPYGENERALIn addition to the naturally occurring metals in the crude oil and the petroleum products derived from it, certain metals are added as additives to lubricating oils and similar products. These metal additives act as detergents, antioxidants, antiwear agents, etc. ...
  • MISTING PROPERTIES OF LUBRICATING FLUIDS: D3705 MISTING PROPERTIES OF LUBRICATING FLUIDS: D3705EXPLANATIONThis test provides a guide for evaluating the misting properties of oils used in industrial mist lubrication systems. The degree of correlation between this test and service performance has not been fully determined. This test method should not ...
  • MERCAPTAN SULFUR IN PETROLEUM PRODUCTS: D3227 MERCAPTAN SULFUR IN PETROLEUM PRODUCTS: D3227(Equivalent Test Methods: IP 342, ISO 3012, JIS K 2276, and AFNOR M07-022)EXPLANATIONMercaptan sulfur has an objectionable odor, an adverse effect on fuel system elastomers, and is corrosive to fuel system components. This test method covers the determination ...
  • DROP MELTING POINT OF PETROLEUM WAX: D127 DROP MELTING POINT OF PETROLEUM WAX: D127(Equivalent Test Methods: IP 133 and ISO 6244)EXPLANATIONDrop melting point test method is often used to measure the melting characteristics of petrolatums and other high viscosity petroleum waxes.TEST SUMMARYSpecimens are deposited on two thermometer bulbs by ...
  • MELTING POINT OF PETROLEUM WAX: D87 MELTING POINT OF PETROLEUM WAX: D87(Equivalent Test Methods: IP 55, ISO 3841, and DIN 51570)EXPLANATIONMelting point (cooling curve) is a test widely used by wax suppliers and consumers. It is particularly applied to petroleum waxes that are rather highly paraffinic or crystalline in nature. A plateau ...
  • MANGANESE IN GASOLINE BY ATOMIC ABSORPTION SPECTROSCOPY (AAS): D3831 MANGANESE IN GASOLINE BY ATOMIC ABSORPTION SPECTROSCOPY (AAS): D3831EXPLANATIONCertain organo-manganese compounds act as anti-knock agents when added to gasoline, usually as methylcyclo-pentadienyl manganese tricarbonyl (MMT). This test method covers the determination of total manganese content of gasoline ...
  • LUMINOMETER NUMBERS OF AVIATION TURBINE FUELS: D1740 LUMINOMETER NUMBERS OF AVIATION TURBINE FUELS: D1740EXPLANATIONThis test method provides an indication of the relative radiation emitted by the combustion products of gas turbine fuels from a diffusion flame. The radiation level is expressed as luminometer number, which is related to the hydrocarbon ...
  • LUBRICITY OF DIESEL FUELS BY HIGH-FREQUENCY RECIPROCATING RIG (HFRR): D6079 LUBRICITY OF DIESEL FUELS BY HIGH-FREQUENCY RECIPROCATING RIG (HFRR): D6079EXPLANATIONDiesel fuel injection equipment has some reliance on lubricating properties of the diesel fuel. Shortened life of engine components such as diesel fuel injection pumps and injectors, has sometimes been ascribed to lack ...
  • LUBRICITY OF AVIATION TURBINE FUELS: D5001 LUBRICITY OF AVIATION TURBINE FUELS: D5001EXPLANATIONWear due to excessive friction resulting in shortened life of engine components such as fuel pumps and fuel controls have sometimes been ascribed to lack of lubricity in an aviation fuel. The relationship of test results to aviation fuel system component ...
