  • VISCOSITY, KINEMATIC OF TRANSPARENT AND OPAQUE LIQUIDS: ASTM D445 VISCOSITY, KINEMATIC OF TRANSPARENT AND OPAQUE LIQUIDS: ASTM 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 ...
  • VISCOSITY, KINEMATIC OF AIRCRAFT TURBINE LUBRICANTS: ASTM D2532 VISCOSITY, KINEMATIC OF AIRCRAFT TURBINE LUBRICANTS: ASTM 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 ...
  • VISCOSITY INDEX: ASTM D2270 VISCOSITY INDEX: ASTM 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 ...
  • 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: ASTM 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 ...
  • KINEMATIC VISCOSITY OF LIQUIDS BY AUTOMATED HOUILLON VISCOMETER: ASTM D7279 KINEMATIC VISCOSITY OF LIQUIDS BY AUTOMATED HOUILLON VISCOMETER: ASTM 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 ...
  • VISCOSITY SCANNING BROOKFIELD VISCOSITY: ASTM D5133 VISCOSITY SCANNING BROOKFIELD VISCOSITY: ASTM 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 ...
  • VISCOSITY BROOKFIELD VISCOSITY: ASTM D2983 VISCOSITY BROOKFIELD VISCOSITY: ASTM 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 ...
  • YIELD STRESS AND APPARENT VISCOSITY OF USED ENGINE OILS AT LOW TEMPERATURE: ASTM YIELD STRESS AND APPARENT VISCOSITY OF USED ENGINE OILS AT LOW TEMPERATURE: ASTM D6896EXPLANATIONWhen an engine oil is cooled, the rate and duration of cooling can affect its yield stress and viscosity. In this test method, used engine oil is slowly cooled through a temperature range where wax crystallization ...
