Low Temperature CMRV Viscosity Table

The low temperature viscosity standards are designed for use with the CANNON Mini-Rotary Viscometer (CMRV) for:

  • ASTM D3829  Predicting the Borderline Pumping Temperature of Engine Oil
  • ASTM D4684  Determination of Yield Stress and Apparent Viscosity of Engine Oils at Low Temperature
  • ASTM D6821  Low Temperature Viscosity of Drive Line Lubricants in a Constant Shear Stress Viscometer
  • ASTM D6896  Determination of Yield Stress and Apparent Viscosity of Used Engine Oils at Low Temperature
  • SAE J300 

Lot specific viscosity data is provided with each standard.

Nominal viscosity values of low temperature CMRV viscosity standards for ASTM D3829, ASTM D4684, ASTM D6821, ASTM D6898 and SAE specification J300

This table presents nominal data. Actual values, provided with each standard, may vary slightly from lot to lot and formulations are subject to change. If your application requires close conformity with published nominal values, please contact technical service to obtain the actual viscosity values associated with the current formulation.
