Manual No. M98-350-J0912
The shear rate of a given measurement is determined by: the rotational speed of the spindle, the
size and shape of the spindle, the size and shape of the container used and therefore, the distance
between the container wall and the spindle surface.
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) Viscometer model
5) Spindle used (if using LVDV-E (#1-4) or RVDV-E (#2-7) 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.
