7) e viscosity reading should equal the cP value on the viscosity standard uid to within the
combined accuracies of the Viscometer and the viscosity standard (as discussed in the section
entitled, Interpretation of Calibration Test Results) which appears later in this section.
Verication Procedure for a Small Sample Adapter
When a Small Sample Adapter is used, the water jacket should be connected to a water bath and the
sample stabilized at the proper temperature:
1) Put the proper amount of viscosity standard uid into the sample chamber. e amount varies
with each spindle/chamber combination. (Refer to the Small Sample Adapter instructions).
2) Place the sample chamber into the water jacket.
3) Put the spindle into the test uid and attach the extension link, coupling nut and free hanging
spindle (or directly attach the solid sha spindle) to the Viscometer.
4) Allow 30 minutes for the viscosity standard, sample chamber and spindle to reach test temperature.
5) Measure the viscosity and record the Viscometer reading.
Note: The spindle must rotate at least ve (5) times before a viscosity reading is taken.
6) e viscosity reading should equal the cP value on the viscosity standard uid to within the
combined accuracies of the Viscometer and the viscosity standard (as discussed in the section
entitled, Interpretation of Calibration Test Results) which appears later in this section.
Verication Procedure for a ermosel System
Before verifying the ermosel and controller, follow the verication procedure for regular spindles
RV/HA/HB 2-6 or LV 61-63. When a ermosel System is used, the controller stabilizes the ermo
Container at the test temperature.
1) Put the proper amount of HT viscosity standard uid into the HT-2 sample chamber. e
amount varies with the spindle used. (Refer to the ermosel instruction manual).
2) Place the sample chamber into the ermo Container.
3) Put the spindle into the test uid and attach the extension link, coupling nut and free hanging
spindle (or directly attach the solid sha spindle) to the Viscometer.
4) Allow 30 minutes for the viscosity standard, sample chamber and spindle to reach test temperature.
5) Measure the viscosity and record the Viscometer reading.
Note: The spindle must rotate at least ve (5) times before a viscosity reading is taken.
6) e viscosity reading should equal the cP value on the viscosity standard uid to within the
combined accuracies of the Viscometer and the viscosity standard (as discussed in the section
entitled, Interpretation of Calibration Test Results) which appears later in this section.
