Appendix E - Calibration Procedures
TheaccuracyoftheDV2TisveriedusingviscositystandarduidswhichareavailablefromBrookeld
Engineering Laboratories or your local Brookeld 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 E-1(SiliconeOils)andTable E-2 (MineralOils).

Container size: ForViscosityStandards<30,000cP,usea600mLLowFormGrifnBeaker
havingaworkingvolumeof500mL.
 ForViscosityStandards≥30,000cP,usetheuidcontainer.
 InsideDiameter: 3.25”(8.25cm)
 Height: 4.75”(12.1cm)
 Note:Containermaybelarger,butmaynotbesmaller.
Temperature: Asstatedontheuidstandardlabel:(+/-)0.1°C
Conditions: TheDV2Tshouldbesetaccordingtotheoperatinginstructions.Thewaterbath
mustbestabilizedattesttemperature.Viscometerswiththeletters“LV”or
“RV”inthemodeldesignationmusthavetheguardlegattached(seeAppendix
