Conclusions:
The vapor pressure of the substance was determined at 5.0 ± 0.7 Pa at 25 °C.
Executive summary:

The vapour pressure of the substance was determined according to the EC Testing Guideline A.4 "Vapour pressure". The determination based on the detection of the evaporation rate from a Knudsen cell of a vapour pressure balance at 25 °C. The measurement of vapour pressure showed a result of 5.0 ± 0.7 Pa at 25 °C.
