CANNON silicone standards are intended for calibration of Brookfield type rotational viscometers, such as the 2020 Series Rotary Viscometers
offered by CANNON. Viscosity data at 20, 23, 24, 25, 26, 27, and 40°C
is provided. CANNON has been granted ISO 9001 registration for the
manufacture and certification of viscosity standards, including the
silicone standards listed here.
Viscosities for all silicone standards sold by CANNON are
based on the National Institute of Standards and Technology (NIST) value
of 1.0016 mPa•s (centipoise) for water at 20°C (68°F). All silicone
standards are traceable to the NIST. Silicone standards are sold in 500
mL bottles.
Note: The listed silicone standards are intended for use
with rotational viscometers only. Silicone standards are not recommended
for glass capillary viscometers (including vacuum viscometers), metal
cup-type viscometers (such as ISO, Zahn, Ford, Shell, and Fisher cups),
or any other viscometers providing kinematic viscosity – CANNON
hydrocarbon-based oil standards should be used for these types of
viscometers.
