Viscosity standards in many types

There are hundreds of different types of viscometers: glass capillary, rotational, viscosity cup, falling ball, and many others.

There are hundreds of different types of viscometers: glass capillary, rotational, viscosity cup, falling ball, and many others.

All viscometers should be checked periodically with a certified viscosity standard to ensure that the accuracy of the instrument is being maintained.

Cannon certified viscosity standards provide kinematic viscosities (in cSt or mm2/s) and viscosities (in cP or mPas) at many temperatures, ranging from -55C to 150C.

If a stock standard does not fulfill your requirements, a custom blended standard can be prepared.

All Cannon viscosity standards, whether stock or custom, are traceable to the NIST (National Institute of Standards and Technology) and are prepared in Cannon's ISO 9001-registered and A2LA-accredited laboratory.

Most viscosity standards supplied by Cannon are hydrocarbon oils.

The lower viscosity standards consist of mineral oil base stocks, and the higher viscosity standards are polybutenes with the exception of N1000, which is a poly-alpha-olefin.

In addition to hydrocarbon standards, Cannon offers silicone standards for calibrating rotational viscometers.

note: Silicone viscosity standards should not be used for other types of viscometers.

Cannon hydrocarbon standards can be used for calibrating any glass capillary viscometers if the specifications and procedures found in ASTM D 445 and ASTM D 446 are strictly followed.

Alternatively it is often more convenient and cost effective to purchase viscometers which have already been calibrated by Cannon.

If you need a standard at a temperature or viscosity not available in a stock standard, please call Labtex to discuss the blending of a custom standard to your temperature and viscosity specifications.
