  • EVAPORATION LOSSES BY THERMO GRAVIMETRIC ANALYSIS (TGA) NOACK METHOD: ASTM D6375 EVAPORATION LOSSES BY THERMO GRAVIMETRIC ANALYSIS (TGA) NOACK METHOD: ASTM D6375EXPLANATIONThis is a safe and fast alternative for the determination of Noack evaporation loss of a lubricant. This test method is applicable to base stocks and fully formulated lubricating oils having a Noack evaporative ...
  • EVAPORATION LOSSES NOACK EVAPORATION LOSS: ASTM D5800 EVAPORATION LOSSES NOACK EVAPORATION LOSS: ASTM D5800(Equivalent Test Methods: IP 421, DIN 51581, and CEC-L14-A88)EXPLANATIONWith the introduction of a maximum volatility limit in European crankcase lubricant specifications there was a requirement for a volatility test with acceptable precision limits, ...
  • EVAPORATION LOSSES OF LUBRICATING GREASES AND OILS: ASTM D972 EVAPORATION LOSSES OF LUBRICATING GREASES AND OILS: ASTM D972EXPLANATIONSee the discussion under Test Method ASTM D2595. This test is run at temperatures between 100 and 150° C (210 to 300° F).TEST SUMMARYSee the discussion under Test Method ASTM D2595.TEST PRECISIONThis test method has a repeatability ...
  • EVAPORATION LOSS OF LUBRICATING GREASES: ASTM D2595 EVAPORATION LOSS OF LUBRICATING GREASES: ASTM D2595EXPLANATIONThe loss of volatile materials from greases and oils can adversely affect the original performance characteristics of a lubricant and therefore, could be a significant factor in evaluating a lubricant for a specific use. Such volatiles can ...
  • ENGINE OIL VOLATILITY BY GC: ASTM D5480 ENGINE OIL VOLATILITY BY GC: ASTM D5480EXPLANATIONThis test method provides the determination of the amount of engine oil volatilized at 700° F (371° C). This test method is applicable to engine oils containing high molecular weight components that need not elute from a GC column. This test method ...
  • EVAPORATION LOSSES BY VOLATILITY: EVAPORATION LOSSES BY VOLATILITY:GENERALA number of methods exist for the determination of engine oil volatility based on gas chromatographic or physical measurements. Evaporation loss is a critical parameter of interest to automobile manufacturers, and is included in several oil lubricant specifications.
  • ETHYLENE GLYCOL IN USED ENGINE OIL: ASTM D4291 ETHYLENE GLYCOL IN USED ENGINE OIL: ASTM D4291EXPLANATIONLeakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method provides for early detection to prevent coolant from accumulating ...
  • ETHYL MERCAPTAN IN LPG VAPOR: ASTM D5305 ETHYL MERCAPTAN IN LPG VAPOR: ASTM D5305EXPLANATIONLPG is colorless and odorless, and not detectable by normal human senses. To provide an olfactory warning in the event of a leak, LPG intended for domestic or commercial use is intentionally odorized so as to be readily detectable well below flammable ...
  • ETHANOL CONTENT IN DENATURED FUEL ETHANOL BY GC: ASTM D5501 ETHANOL CONTENT IN DENATURED FUEL ETHANOL BY GC: ASTM D5501EXPLANATIONFuel ethanol is required to be denatured with gasoline in accordance with Specification ASTM D4806. State and federal laws specify the concentration of ethanol in gasoline blends. Hence, the determination of the amount of denaturant ...
  • ENGINE OIL VOLATILITY BY CAPILLARY GAS CHROMATOGRAPHY: ASTM D6417 ENGINE OIL VOLATILITY BY CAPILLARY GAS CHROMATOGRAPHY: ASTM D6417EXPLANATIONThe determination of engine oil volatility at 371° C is a requirement in some lubricant specifications. This test method is intended as an alternative to Test Methods ASTM D5800 and ASTM D5480. The data obtained by this test ...
