Applicant's summary and conclusion

Conclusions:
The vapour pressure was measured in the range of 26 to 150 °C. No signal was observed in the entire range, meaning that the vapour pressure was below the detection limit of 10 (exp-5) hPa. Subsequently the vapour pressure at 20, 25 and 50 °C was calculated.
Executive summary:
