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.
Brookfield Engineering Laboratories does not re-certify Viscosity Standard Fluids. We will is-
sue duplicate copies of the Certificate of Calibration for any fluid within two years of purchase
date. Brookfield Viscosity Standard Fluids are reusable provided they are not contaminated.
Normal practice for usage in a 600 mL beaker is to return the material from the beaker back
into the bottle.
Calibration Check Procedure
1) Shut off the rheometer.
2) Place the viscosity standard fluid (in the proper container) into the water bath.
3) Press and hold the ↓ and ↑ keys simultaneously while turning the rheometer power ON.
