Additional information
Measured kinematioc viscosities of 0.8406 mm2 s-1 at 20 °C and 0.6716 mm2 s-1 at 40 °C were determined by capillary method according to an internal method. The results are considered to be reliable.
This is supported by a predicted static viscosity value of 1.3 mm2 s-1 at 20 °C obtained using an appropriate calculation method.
