The viscosity of the test article was determined using a Cannon-Fenske
viscometer (type routine, size 200, I.D. # P251), which was
calibrated with a Cannon(R) certified viscosity standard (I.D. #
N10 with kinematic viscosity of 17.72 cSt at 25.00 °C) in a constant
temperature water bath maintained at 25.0 +- 0.1 °C. The calibration
constant of the viscometer was calculated for use in determining the
test article viscosity. The procedure was considered acceptable and the
calculated average efflux time was used to determine the calibration
constant of the viscometer.
The viscosity measurement was conducted in triplicate on one sampling of
test article as supplied in a constant temperature water bath maintained
at 25.0 +- 0.1 °C. The three efflux time measurements for the test
article were within 0.5% of their average value, the procedure was
considered acceptable and the calculated average efflux time was used to
calculate the kinematic viscosity of the test article. The kinematic
viscosity of the test article was determined to be 21.70 cSt at 25.0 °C.
