Vapour pressure:
< 0 Pa
Remarks on result:
other: Vapour pressure values were calculated as conservative estimates, based on a lack of any detectable vapour pressure of the test item up to 150.2°C, and the detection limit of the method, i.e. 10^-5 hPa.

Applicant's summary and conclusion

Conclusions:
Vapour pressure (<<0.00001 Pa) was calculated as conservative estimates, based on a lack of any detectable vapour pressure of the etst item up to 150.2°C, and the detection limit of the method, i.e. 10^-5 hPa.
