A repeatable viscosity test should control or specify the following:

1) Test temperature

2) Sample container size (or spindle/chamber geometry)

3) Sample volume

4) Rheometer model

5) Spindle used (if using LVDV-III Ultra (#1-4) or RVDV-III Ultra (#1-7) attach the guard leg)

6) Test speed or speeds (or the shear rate)

7) Length of time or number of spindle revolutions to record viscosity.
