  • GLYCERIN IN BIODIESEL METHYL ESTERS BY GC: D6584 GLYCERIN IN BIODIESEL METHYL ESTERS BY GC: D6584EXPLANATIONFree and bonded glycerin content reflects the quality of biodiesel. A high quantity of free glycerin may cause problems during storage, or in the fuel system, due to separation of the glycerin. A high total glycerin content can lead to injector ...
  • GASOLINE DILUENT IN USED ENGINE OILS (GAS CHROMATOGRAPHY METHOD): D3525 GASOLINE DILUENT IN USED ENGINE OILS (GAS CHROMATOGRAPHY METHOD): D3525TEST SUMMARYThis test method uses a gas chromatograph equipped with a flame ionization detector and a programmable oven. The use of other detectors and instrumentation has been reported. However, the precision statement applies only ...
  • GASOLINE DILUENT IN USED ENGINE OILS (DISTILLATION METHOD): D322 GASOLINE DILUENT IN USED ENGINE OILS (DISTILLATION METHOD): D322GENERAL:Some fuel dilution of the engine oil may take place during normal operation. However, excessive fuel dilution is of concern in terms of possible performance problems. There are two test methods available for this work: one based ...
  • GAGE VAPOR PRESSURE OF LPG: D1267 GAGE VAPOR PRESSURE OF LPG: D1267EXPLANATIONInformation on the vapor pressure of LPG products under temperature conditions from 37.8 to 70° C is pertinent to selection of properly designed storage vessels, shipping containers, and customer utilization equipment to ensure safe handling of these products. ...
  • FUEL SYSTEM ICING INHIBITORS IN AVIATION FUELS: D5006 FUEL SYSTEM ICING INHIBITORS IN AVIATION FUELS: D5006EXPLANATIONDiethylene Glycol Monomethyl Ether (DiEGME) is miscible with water and can be readily extracted from the fuel by contact with water during shipping and in storage. Methods are therefore needed to check the additive content in the fuel to ...
  • FRICTION AND WEAR PROPERTIES OF EXTREME PRESSURE LUBRICATING OILS: D6425 FRICTION AND WEAR PROPERTIES OF EXTREME PRESSURE LUBRICATING OILS: D6425(Equivalent Test Method: DIN 51834)EXPLANATIONThis test method can be used to determine anti-wear properties and coefficient of friction of extreme pressure (EP) lubricating oils at selected temperatures and loads in applications ...
  • FRETTING WEAR PROTECTION BY LUBRICATING GREASES: D4170 FRETTING WEAR PROTECTION BY LUBRICATING GREASES: D4170EXPLANATIONThis test method is used to evaluate the property of lubricating greases to protect oscillating bearings from fretting wear. It is used for specification purposes, and differentiates between greases allowing low, medium, and high amounts ...
  • FREEZING POINT OF HIGH PURITY HYDROCARBONS: D1015 FREEZING POINT OF HIGH PURITY HYDROCARBONS: D1015EXPLANATIONA knowledge of the purity of the hydrocarbons is often needed to help control their manufacture and to determine their suitability for use as reagent chemicals or for conversion to other chemical intermediates or finished products. The freezing ...
  • FREEZING POINT: D5972 FREEZING POINT: D5972(Equivalent Test Method: IP 435)This is an automated phase transition method used in the temperature range -80 to 20° C. Results by this test method have a resolution of 0.1° C, and have a precision better than that of Test Method D2386. It also eliminates most of the operator ...
  • FREEZING POINT: D5901 FREEZING POINT: D5901(Equivalent Test Method: IP 434)This is an automated optical method used for the temperature range 0 to -70° C. Results by this test method have a resolution of 0.1° C. A 25-mL portion of the fuel is placed in a test chamber, which is cooled while continuously being stirred and ...
