The values indicated are extrapolated (linear) from measurements between 80 and 90 °C. Ten runs were included in the study. The results of the last 3 runs showed that equilibrium had been reached and were used for calculations.

Conclusions:
The vapour pressure of the substance is 1.6E-05 Pa
Executive summary:

Using the vapour pressure balance method, the vapour pressure of the substance has been determined to be 1.6E-05Pa.
