Applicant's summary and conclusion

Conclusions:

Refer to attached study report. The vapour derived from the study is 2.04E-03 Pa at 60°C.

Executive summary:

At all experiments no reproducible weight loss was observed. At 90 °C the test item was nearly completely bubbled over. Therefore it was not possible to determine the vapour pressure thusly. Also a calculation of the vapour pressure using EPIwin is not possible because the test item is 100 % UVCB. Only the highest value of the vapour pressure, derived from all measurements can be stated with 2.04*10-03 Pa at 60 °C with a standard deviation of 1.43*10-04 Pa. Therefore, the result of the test can be considered valid.
