Key result
Temp.:
40°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
ca. 24 140
Temp.:
20°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
> 100 000
Conclusions:
The viscosity of the test material was determined to be 24140 cSt at 40°C (mean of two values) and >100000 cSt at 20 °C.

Description of key information

Test was conducted according to the ASTM D445 method, this is considered to be comparable to OECD 114.
The viscosity of the test material was determined to be 24140 cSt at 40 °C and > 100000 cSt at 20 °C.

Key value for chemical safety assessment

Viscosity:
24 140 mm²/s (static)
at the temperature of:
