1.1This test method covers the laboratory determination of the viscosity of engine oils at 100°C and 1·106s –1 using the Tapered Bearing Simulator (TBS) viscometer.2
1.2The Newtonian calibration oils used to establish this test method range from approximately 5 to 12 mPa·s (cP) at 100°C and either the manual or automated protocol was used by each participant in developing the precision statement. The viscosity range of the test method at this temperature is from 1 mPa·s (cP) to above 25 mPa·s (cP), depending on the model of TBS.
1.3The non-Newtonian reference oil used to establish the shear rate of 1·106s–1 for this test method has a viscosity of approximately 10 mPa·s at 100°C.
1.4Application to petroleum products other than engine oil has not been determined in preparing the viscometric information for this test method.
