Any other information on results incl. tables

The vapour pressure values were calculated as conservative estimates, based on a lack of any detectable vapour pressure of the test item up to 149.8 °C, and the detection limit of the method, i.e. 10-5 hPa.

Applicant's summary and conclusion

Conclusions:
The calculated vapour pressure values are << 0.0000001 hPa at 20, 25 and 50 °C.
Executive summary:

The vapour pressure values were calculated as conservative estimates, based on a lack of any detectable vapour pressure of the test item up to 149.8 °C, and the detection limit of the method, i.e. 10-5hPa.
