Apparatus for Viscosity by TBS
Apparatus for Viscosity by TBS TT-4683
Apparatus for Viscosity by TBS TT-4683 conforms to ASTM D4683 Standard Test Method for Measuring Viscosity of New and Used Engine Oils at High Shear Rate and High Temperature by Tapered Bearing Simulator Viscometer at 150 °C and ASTM D4741 Standard Test Method for Measuring Viscosity at High Temperature and High Shear Rate by Tapered-Plug Viscometer.
ASTM D4683 entails the laboratory determination of engine oil viscosity at 150°C and 1.0 x 10^6 s^-1 utilizing a viscometer equipped with a slightly tapered rotor and stator, known as the Tapered Bearing Simulator (TBS) Viscometer.
