CANNON Instrument Company has released a new line of viscosity check
oils specifically designed for verification of SAE target viscosities
per ASTM D 445, D 5293, and D 4684.
The CVCO (Certified Viscosity Check Oil) series includes
formulated commercial engine oils with certified values for kinematic
viscosity in mm²/s (cSt) at 40 and 100°C, cranking viscosity in mPa·s
(cP) at old and new SAE J300 specification temperatures, pumping
viscosity in mPa·s (cP) at SAE J300 specification temperatures, and
density in g/mL at 15°C.
These new materials are available in 1 L (Qts) and 3.8 L (1 Gallon) sizes.
The oils enable users to “check” the performance of their
Cold-Cranking Simulator, Mini-Rotary Viscometer, and Kinematic
Viscometers by measuring commercially-available formulated engine oils.
Viscosity values for the check oils will be at typical blend targets.
Custom check oils with customer-specified blend targets may also be
requested. Precision of the new check oils will be equivalent to the
existing CANNON standard lines. CANNON will provide all necessary
calibration certification with all Viscosity Check Oils.
