APPENDIX D - Calibration Procedures

The accuracy of the Dial Viscometer is verified using viscosity standard fluids which are available from

Brookfield Engineering Laboratories or your local Brookfield agent. Viscosity standards are Newtonian,

and therefore, have the same viscosity regardless of spindle speed (or shear rate). Viscosity standards,

calibrated at 25°C, are shown in Table D1.

Container size: For Viscosity Standards <30,000 cP, use a 600 ml Low Form Griffin Beaker

having a working volume of 500 ml.

For Viscosity Standards ≥30,000 cP, use the fluid container.

Inside Diameter: 3.25"(8.25cm)

Height: 4.75"(12.1cm)

Note: Container may be larger, but may not be smaller.

Temperature: As stated on the fluid standard label: (±) 0.1°C

Conditions: The Viscometer should be set according to the operating instructions. The water

bath should be stabilized at test temperature. Viscometers with the letters “LV”

or “RV” in the model designation should have the guard leg attached.

Brookfield Viscosity Standard Fluid General Information

We recommend that Brookfield Viscosity Standard Fluids be replaced on an annual basis, one year

from date of initial use. These fluids are pure silicone and are not subject to change over time.

However, exposure to outside contaminants through normal use requires replacement on an annual

basis. Contamination may occur by the introduction of solvent, standard of different viscosity or

other foreign material.

Viscosity Standard Fluids may be stored under normal laboratory conditions. Disposal should be in

accordance with state, local and federal regulations as specified on the material safety data sheet.
