In practical operation, this safety can, however, be achieved only if all necessary measures are taken. The obligation of the plant operator to exercise due care includes planning these measures and supervising their execution.
- Page 5 1.3 Obligation of the personnel to exercise due care The ViscoIndicator melt rheometer may only be operated by persons trained, instructed and authorized to do so. These persons must know the operating instructions and act accordingly. The respective competences of the staff must be clearly determined.

Page 41: Using Activation Energy With The Viscoindicator
Using Activation Energy with the ViscoIndicator Often, the temperature at which the polymer is being processed at is not the same as the test temperature used in the lab to verify the melt flow index. A polymer’s melt flow index is dependent upon its temperature. Therefore, if the polymer is processed at a different temperature from the lab, there can be a difference in melt flow indexes. -
Page 42: Viscoindicator Calibration
ViscoIndicator calibration Dynisco recommends the following steps: 1- Run the VI in “Pressure Mode” setting the pressure set point equal to the standard pressure from ASTM standard weight for the material. 2- Once the pressure on the PV screen matches the set point, read the value of pump speed from the screen. - Page 43 . The expected extrudate weight would be: = 0.663 ∗ 7 ∗ .5 = 2.32 Deviation from this value, by more than a couple of percent can be caused by errors in the melt density value.

The ViscoIndicator allows for this with a correlation factor which is a simple scalar that can be used for individual materials, if needed.

Page 47: Warranty
As the guarantee period, DYNISCO grants a 12-month guarantee from the date of delivery, when the ViscoIndicator is used in single-shift operation. If it is used in multiple-shift operation, the duration of the guarantee is reduced to 6 months.
