  • HINDERED PHENOLIC AND AROMATIC AMINE ANTIOXIDANT CONTENT IN NON-ZINC TURBINE OIL HINDERED PHENOLIC AND AROMATIC AMINE ANTIOXIDANT CONTENT IN NON-ZINC TURBINE OILS BY LINEAR SWEEP VOLTAMMETRY: D6971EXPLANATIONThis test method covers the voltammetric determination of hindered phenol and aromatic amine antioxidants in new or used type non-zinc turbine oils in concentrations from 0.0075 ...
  • HIGH TEMPERATURE UNIVERSAL OXIDATION TEST FOR TURBINE OILS: D6514 HIGH TEMPERATURE UNIVERSAL OXIDATION TEST FOR TURBINE OILS: D6514EXPLANATIONDegradation of fluid lubricants because of oxidation or thermal breakdown can result in fluid thickening or in the formation of acids or insoluble solids and render the fluid unfit for further use as a lubricant. This test method ...
  • HIGH TEMPERATURE STABILITY OF DISTILLATE FUELS: D6468 HIGH TEMPERATURE STABILITY OF DISTILLATE FUELS: D6468EXPLANATIONThis test method provides an indication of thermal oxidative stability of distillate fuels when heated to high temperatures that simulate those that may occur in some types of recirculating engine or burner fuel delivery systems. Results ...
  • HIGH TEMPERATURE DEPOSITS BY TEOST: D6335 HIGH TEMPERATURE DEPOSITS BY TEOST: D6335EXPLANATIONThe test method is designed to predict the high temperature deposit forming tendencies of an engine oil. This test method can be used to screen oil samples or as a quality assurance tool. It utilizes the thermo-oxidation engine oil simulation test (TEOST). ...
  • SEPARABILITY NUMBER OF HEAVY FUEL OILS BY OPTICAL SCANNING DEVICE: D7061 SEPARABILITY NUMBER OF HEAVY FUEL OILS BY OPTICAL SCANNING DEVICE: D7061EXPLANATIONThis procedure describes a rapid and sensitive method for estimating the stability reserve of an oil. The stability reserve is estimated in terms of a separability number, where a low value of separability number indicates ...
