For the kinematic liquid viscosity measurement, SIOP 5.54, CTM 0004, ASTM D445-09, and ASTM D446-07 were followed. The tube was calibrated using 2 different Cannon viscosity standards and then averaging these calibration factors. There were three meniscus drop times that were averaged and used for each viscosity determination.

Conclusions:
A kinematic viscosity value of 6.4±0.3 mm²/s (static) at 25°C was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
Executive summary:

The kinematic viscosity of the test substance was determined using a capillary method in accordance with ASTM D446 -07 and in compliance with GLP.
