SOP on Calibration of Viscometer (oscillatory)

 Calibration of Viscometer (oscillatory)


1.0  PURPOSE  

 The purpose of the standard operating procedure is
to provide guidelines for calibration of

 Viscometer (oscillatory).

2.0  SCOPE     

       The scope of this standard operating procedure
includes calibration of  
Viscometer (oscillatory).

  Switch on the instrument.

4.2   Using the standard operating conditions
start the operations of the instrument.

4.3   Select the proper spindle number i.e. L1,
L2, L3, L4 depending upon the range of
viscosity to

         be determined and attach to the

   Ensure that the spindles are cleaned
before and after use.

4.4   Select the proper speed in RPM depending upon
the range of viscosity to be determined.

  Control the temperature of the sample
at which the viscosity is to be determined.

4.6   Immerse the spindle in the sample container
up to the set point mark. The spindle should

        not touch the container in any way.

  Start the instrument at the selected
speed and record the viscosity in cps units.

  Change the speed of the spindle and
record the viscosity in cps units.

  The viscosity should not differ with
change in the speed of the spindle.

Correlate the observed values of viscosity with the stated values of the
reference standard

         and make adjustments, if necessary.
