  • SHEAR STABILITY OF POLYMER CONTAINING FLUIDS USING A EUROPEAN DIESEL INJECTOR AP SHEAR STABILITY OF POLYMER CONTAINING FLUIDS USING A EUROPEAN DIESEL INJECTOR APPARATUS: D7109EXPLANATIONThis test method evaluates the percent viscosity loss of fluids resulting from physical degradation in the high shear nozzle device. Thermal or oxidative effects are minimized. This test method may ...
  • SONIC SHEAR STABILITY OF POLYMER-CONTAINING OILS: D2603 SONIC SHEAR STABILITY OF POLYMER-CONTAINING OILS: D2603EXPLANATIONThis test method covers the evaluation of the shear stability of an oil sample containing polymer in terms of the permanent loss in viscosity that results from irradiating an oil sample in a sonic oscillator. This test method can be useful ...
  • SONIC SHEAR STABILITY OF HYDRAULIC FLUID: D5621 SONIC SHEAR STABILITY OF HYDRAULIC FLUID: D5621EXPLANATIONThis test method permits the evaluation of shear stability with minimum interference from thermal and oxidative factors that may be present in some applications. It is applicable to fluids containing both readily sheared and shear-resistant polymers. ...
  • SONIC SHEAR STABILITY OF POLYMER-CONTAINING FLUIDS: D6278 SONIC SHEAR STABILITY OF POLYMER-CONTAINING FLUIDS: D6278EXPLANATIONThis test method evaluates the percent viscosity loss for polymer-containing fluids resulting from polymer degradation in the high shear nozzle device. Thermal or oxidative effects are minimized. This test method is not intended to predict ...
  • SONIC SHEAR STABILITY INDEX: D3945 SONIC SHEAR STABILITY INDEX: D3945EXPLANATIONThese test methods (Kurt Orbahn) measure the percent viscosity loss at 100° C of polymer-containing fluids when evaluated by either of two diesel injector apparatus procedures. Procedure A uses European Diesel Injector Test Equipment and Procedure B uses ...
  • LUBRICITY OF DIESEL FUELS BY SLBOCLE: D6078 LUBRICITY OF DIESEL FUELS BY SLBOCLE: D6078EXPLANATIONDiesel fuel injection equipment has some reliance on lubricating properties of diesel fuel. Shortened life of engine components, such as diesel fuel injection pumps and injectors, has sometimes been ascribed to lack of lubricity in a diesel fuel. ...
  • SEDIMENT TESTS WATER AND SEDIMENT IN MIDDLE DISTILLATE FUELS: D2709 SEDIMENT TESTS WATER AND SEDIMENT IN MIDDLE DISTILLATE FUELS: D2709EXPLANATIONAppreciable amounts of water and sediment in a fuel oil tend to cause fouling of the fuel handling facilities and to give trouble in the fuel system of a burner or engine. An accumulation of sediment in storage tanks and on ...
  • SEDIMENT TESTS WATER AND SEDIMENT IN CRUDE OIL: D96 SEDIMENT TESTS WATER AND SEDIMENT IN CRUDE OIL: D96EXPLANATIONA determination of sediment and water content is required to determine accurately the net volume of crude oil involved in sales, taxation, exchanges, inventories, and custody transfers. An excessive amount of sediment and water in crude oil ...
  • TOTAL SEDIMENT IN RESIDUAL FUELS: D4870 TOTAL SEDIMENT IN RESIDUAL FUELS: D4870(Equivalent Test Methods: IP 375 and ISO 10307)EXPLANATIONAppreciable amounts of sediment in a residual fuel oil can foul the handling facilities, and give problems in burner mechanisms. Sediment can accumulate in storage tanks, on filter screens, or on burner parts, ...
  • SEDIMENT TESTS IN TRACE SEDIMENT IN LUBRICATING OILS: D2273 SEDIMENT TESTS IN TRACE SEDIMENT IN LUBRICATING OILS: D2273EXPLANATIONExcessive amounts of sediment in oil could lead to system malfunction in critical applications. This test method measures the trace level amounts (<0.05 volume %) of naptha-insoluble sediment that can be separated by centrifugation. ...
