Any other information on results incl. tables

The first two runs were high and variable, which was consistent with the loss of impurities

and degassing of the sample and therefore the data was not reported.

Applicant's summary and conclusion

Conclusions:
The substance's vapour pressure at 25°C was determined to be 0.00024 Pa.
Executive summary:

The substance's vapour pressure was studied in accordance with EU Method A.4 and OECD Guideline 104 via a GLP-certified laboratory. Using the pressure balance method the vapour pressure of the substance at 25°C was determined to be 0.00024 Pa.
