Brookeld Viscosity Standard Fluid - General Information

We recommend that Brookeld Viscosity Standard Fluids be replaced on an annual basis, one year

from date of initial use. These uids are either pure silicone or mineral oil 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. Mineral oils should

be stored in the container in which they are supplied. Disposal should be in accordance with state,

local and federal regulations as specied on the material safety data sheet; MSDS information is

available upon request on our website to down load.

Brookeld Engineering Laboratories does not recertify Viscosity Standard Fluids. We will issue

duplicate copies of the Certicate of Calibration for any uid within two years of the purchase date.

Brookeld 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. When using smaller volumes in accessories such as Small Sample Adapter, UL Adapter,

Thermosel or Spiral Adapter, the uid is normally discarded.

Calibration Check Procedure for LV (#1-3) and RV,HA,HB (#1-6) Brookeld Spindles

NOTE: The LV #4 (#64) and the RV, HA, HB #7 spindle have been omitted from this

procedure. Brookeld does not recommend the use of these spindles to perform

a calibration check on your instrument. Reasons pertain to the small amount of

spindle surface area that makes contact with the viscosity standard, the difculty

of establishing the immersion mark precisely and the need for precise temperature

control at 25°C in the immediate vicinity of the spindle.
