  • LOW TEMPERATURE VISCOSITY OF DRIVE LINE LUBRICANTS IN A CONSTANT SHEER STRESS VI LOW TEMPERATURE VISCOSITY OF DRIVE LINE LUBRICANTS IN A CONSTANT SHEER STRESS VISCOMETER: D6821EXPLANATIONViscosity of drive line lubricants at low temperature is critical for both gear lubrication and the circulation of the fluid in automatic transmissions. For gear oils, the issue is whether the fluid ...
  • VISCOSITY, SAYBOLT: D88 VISCOSITY, SAYBOLT: D88EXPLANATIONThis test method covers the empirical procedures for determining the Saybolt Universal or Saybolt Furol viscosities of petroleum products at specified temperature between 21 and 99° C (70 and 210° F).Test Methods D445 and D2170 are preferred for the determination of ...
  • VISCOSITY, KINEMATIC OF VOLATILE AND REACTIVE LIQUIDS: D4486 VISCOSITY, KINEMATIC OF VOLATILE AND REACTIVE LIQUIDS: D4486EXPLANATIONKinematic viscosity is a physical property that is of importance in the design of systems in which flowing liquids are used or handled. This test method is applicable to transparent Newtonian liquids that because of their reactivity, ...
  • VISCOSITY, KINEMATIC OF TRANSPARENT AND OPAQUE LIQUIDS: D445 VISCOSITY, KINEMATIC OF TRANSPARENT AND OPAQUE LIQUIDS: D445(Equivalent Test Methods: IP 71-1, SO 3104, DIN 51562, JIS 2283 and AFNOR T60-100)EXPLANATIONThis test method covers the determination of the kinematic viscosity of liquid petroleum products, both transparent and opaque, by measuring the time ...
  • VISCOSITY, KINEMATIC OF AIRCRAFT TURBINE LUBRICANTS: D2532 VISCOSITY, KINEMATIC OF AIRCRAFT TURBINE LUBRICANTS: D2532EXPLANATIONAircraft turbine lubricants, upon standing at low temperatures for prolonged periods of time, may show an increase in kinematic viscosity. This increase may cause lubrication problems in aircraft engines. Thus, this test method is used ...
  • VISCOSITY INDEX: D2270 VISCOSITY INDEX: D2270(Equivalent Test Methods: IP 226, ISO 2909, and AFNOR T60-136)EXPLANATIONThe Viscosity Index is a widely used and accepted measure of the variation in kinematic viscosity due to changes in the temperature of a petroleum product between 40 and 100° C. Viscosity index is an arbitrary ...
  • VISCOSITY AT HIGH SHEAR RATE BY TAPERED BEARING SIMULATOR VISCOMETER AT 100° C: VISCOSITY AT HIGH SHEAR RATE BY TAPERED BEARING SIMULATOR VISCOMETER AT 100° C: D6616EXPLANATIONViscosity at the shear rate and temperature of this test method is thought to be particularly representative of bearing conditions in large medium speed reciprocating engines as well as automotive and heavy ...
  • KINEMATIC VISCOSITY OF LIQUIDS BY AUTOMATED HOUILLON VISCOMETER: D7279 KINEMATIC VISCOSITY OF LIQUIDS BY AUTOMATED HOUILLON VISCOMETER: D7279EXPLANATIONThe Houillon viscometer tube method offers automated determination of kinematic viscosity. A typically a sample volume of less than 1 mL is required for the analysis. The method is applicable to both fresh and used lubricating ...
  • SCANNING BROOKFIELD VISCOSITY: D5133 SCANNING BROOKFIELD VISCOSITY: D5133EXPLANATIONThe low-temperature, low-shear, rheological behavior of an engine oil plays a major role in determining whether the oil will flow to the inlet screen and then to the oil pump in sufficient quantities that the oil pump will be able to supply lubricant to ...
  • BROOKFIELD VISCOSITY: D2983 BROOKFIELD VISCOSITY: D2983(Equivalent Test Methods: IP 267, ISO 9262, and AFNOR T42-011)GENERALMany petroleum products are used as lubricants for bearings, gears, compressor cylinders, hydraulic equipment, etc. The proper operation of the equipment depends upon the proper kinematic viscosity or viscosity ...
