Container size:Temperature:For Viscosity Standards < 30,000 cP, use a 600 ml Low Form GriffinBeaker having a working volume of 500 ml.For Viscosity Standards >/= 30,000 cP, use the fluid container.Inside Diameter: 3.25” (8.25 cm)Height:4.75” (12.1 cm)Note: Container may be larger, but may NOT be smaller!As stated on the fluid standard label (±) 0.1°CBrookfield Viscosity Standard Fluid General InformationWe recommend that Brookfield Viscosity Standard Fluids be replaced on an annual basis, oneyear from date of initial use. These fluids are pure silicone and are not subject to change overtime. However, exposure to outside contaminants through normal use requires replacement onan annual basis. Contamination may occur by the introduction of solvent, standard of differentviscosity or other foreign material.Viscosity Standard Fluids may be stored under normal laboratory conditions. Disposal shouldbe in accordance with state, local, and federal regulations as specified on the material safety datasheet.Brookfield Engineering Laboratories does not re-certify Viscosity Standard Fluids. We willissue duplicate copies of the Certificate of Calibration for any fluid within two years of purchasedate. 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 intothe bottle. When using smaller volumes in accessories such as the Small Sample Adapter, ULAdapter, or Thermosel, the fluid is normally discarded.Calibration Check Procedure1) 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.Figure C1 appears on the rheometer display.RHEOMETER SETUPENTER TO STARTFigure C14) Press the ENTER key and Figure C2 appears on the rheometer display.CAL VERIFY?NO THEN ENTERFigure C2Using the or key, set the CAL VERIFY setting to YES, then press the ENTER key. FigureC3 appears on the rheometer display. Ensure the rheometer is level, and remove any attachedspindle before auto-zeroing.Brookfield Engineering Labs., Inc. Page 34 Manual No. M/02-215

Speeds between0.1 and 100 rpm are available for use in checking the calibration. Once a speed is selectedby pressing the ENTER key, the spindle rotates at this speed, and % Torque and a Viscosityvalue are displayed, and the S71 begins flashing.11) Use the and keys to select the spindle to be used for the calibration check. All standardBrookfield spindles in addition to any pre-programmed special spindles may be used to checkthe calibration of the instrument. Once a spindle is selected by pressing the ENTER key, theviscosity value is computed and displayed. Pressing the ener key toggles between the spindleand speed fields.Note: The spindle must rotate at least five (5) times before readings are taken.12) The viscosity reading should equal the cP value on the viscosity fluid standard to within thecombined accuracies of the Rheometer and the viscosity standard fluid as discussed in thefollowing section (Interpretation of Calibration Test Results).Brookfield Engineering Labs., Inc.
