Additional information
| Significance and Use | ||||||||
|
Viscosity values at the shear rate and temperature of this test method have been indicated to be related to the viscosity providing hydrodynamic lubrication in automotive and heavy duty engines in severe service. The viscosities of engine oils under such high temperatures and shear rates are also related to their effects on fuel efficiency and the importance of high shear rate, high temperature viscosity has been addressed in a number of publications and presentations. |

| 1. Scope | ||||||||
|
1.1 This test method covers the laboratory determination of the viscosity of engine oils at 150 °C and 1.0·106 s−1 using a viscometer having a slightly tapered rotor and stator called the Tapered Bearing Simulator (TBS) Viscometer. |
