The kinematic viscosity of the test item at 20°C and 40°C was 6.71 mm2/s and 3.25 mm2/s, respectively.
Executive summary:

The kinematic viscosity of Tetramethylammonium hydroxide 35% in water was determined using the capillary viscometer method in a GLP study according to OECD 114 and OPPTS 830.7100

The kinematic viscosity at 20°C and 40°C was determined in duplicate obtaining the mean values of 6.71 mm^2/s and 3.25 mm^2/s, resp.
