Conclusions:
The kinematic viscosity of pure 1,3,5-trimethylhexahydro-1,3,5-triazine was 3.7mm2.s−1 at 20˚C and 3.5mm2.s−1 at 25˚C.
Executive summary:

The kinematic viscosity of pure 1,3,5-trimethylhexahydro-1,3,5-triazine was 3.7mm2.s−1at 20˚C and 3.5mm2.s−1 at 25˚C.  The viscosity was determined on a calibrated LV Brookfield digital viscometer with associated spindle 61 at 100 revolutions per minute.  Two calibrated 76mm immersion thermometers (Brannan and Fisherbrand [305mm length]), of 1˚C graduations from -10˚C to 110˚C) were used to monitor the temperature.  Note: Thermometers were removed from liquid during reading so as not to interfere with dynamics.
