Key result
Temp.:
20°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
2.12

The kinematic viscosity of the test item was measured with a micro-Ubbelohde viscometer according to DIN 51 562 at 20°C and 40°C as preferred by the OECD Guideline 114 (“Viscosity of Liquids”)

Kinematic viscosity at 20°C : 2.12 mm²/s

Kinematic viscosity at 40°C : 1.46 mm²/s

Conclusions:
In a valid guideline study the Kinematic viscosity at 20°C= 2.12 mm²/s.
Executive summary:

In a valid guideline study the Kinematic viscosity at 20°C = 2.12 mm²/s.
