4. Summary of Test Method
4.1 Viscosity is the primary dependent parameter and either torque or rotational speed is the primary independent parameter
measured by rotational viscometry. Viscosity is strongly dependent upon temperature and so temperature is usually held constant.
4.2 Viscosity is validated by the direct measurement using a concentric cylinder rotational viscometer at an isothermal temperature
using reference materials of known viscosity as an analyte.
4.3 Alternatively, validation of a rotational viscometry method based upon viscosity measurement may be performed using a
specific test specimen as the analyte.
4.4 The viscosity of three or more specimens, nominally representing the minimum, midpoint and maximum of the range of the
test method, are measured at least in triplicate.
NOTE 1—Repeatability is determined by performing a sufficient number of determinations to calculate statistically valid estimates of the standard deviation
or relative standard deviation of the measurements.
