CANNON certified viscosity check oils verify SAE target viscosities for kinematic viscometers, cold-cranking simulators and mini-rotary viscometers per ASTM D445, D5293 and D4684 respectively. Each check oil contains a commercial engine oil with certified values at common blend target values for density in g/cm³ (g/mL) at 15 °C, kinematic viscosity in mm²/s (cSt) at 40 °C and 100 °C as well as cranking and pumping viscosities in mPa∙s (cP) at SAE J300 specification temperatures. CANNON certified viscosity check oils are available in 1 L (quart) and 3.8 L (gallon) sizes.

Low Temperature Viscosity Standards (General, CCS and CMRV)

CANNON silicone viscosity standards are intended for use with rotational viscometers only. Silicone viscosity standards are not recommended for glass capillary viscometers (including vacuum viscometers), metal cup-type viscometers (such as ISO, Zahn, Ford and Shell cups), or any other viscometers providing kinematic viscosity—CANNON hydrocardon-based oil standards should be used for these types of viscometers.

CANNON silicone viscosity standards are specifically formulated for use with rotational viscometers. Lot specific viscosity data in mPa·s (cP) at 20 °C, 23 °C, 24 °C, 25 °C, 26 °C, 27 °C and 40 °C is provided with each standard. Viscosity standards are sold in 500 mL bottles.
