Viscosity Standards for Cone/Plate, Stormer Rotothinner and all other Viscometers

The Quality Control Laboratory has developed with Cannon Instruments a unique listing of Calibration Standards. These standards are calibrated over 6 temperatures from 20 degrees Centigrade to 27.0 Centigrade. These oils are now packaged so they can be used for any Viscometer.

The following table related to a direct comparison to calibration oils supplied by The Paint Research Association( PRA ).

Note: P.R.A. calibration oils are accurate to no better then plus or minus 1% at best. The following oils have an accuracy of +/- 0.2%.

P.R.A. Number	Q.C.L. Number	Dynamic Viscosity Poise at 25.0 Cent
1	FM50	0.5
2	FM75	0.75
3	FM100	1

17	FM8000	80
18	FM10000	100
19	FM15000	150
20	FM20000	200

Viscosity standards are based on the National bureau of Standards value of 1.002 centipoise for water at 20 degrees Centigrade. All Standards are traceable to the National Bureau of Standards ( NBS ) / National Institute of Standards and Technology ( NIST ).

Calibration Kits For Cone & Plate Viscometers Comprising:

Kit 1 – Contains 1, 3, 5, 7 POISE

Kit 2 – Contains 5, 7, 10, 25 POISE

Kit 3 – Contains any 4 from above Kit 1 & 2

Enables end user to calibrate using small samples at a low cost. ( Supplied with certification )

These standards can also be used for other Cones & Plates ( i.e. Brookfield and Haake ).
