Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item was calculated as follows:
0.015 Pa at 20 °C
0.043 Pa at 25 °C
2.4 Pa at 50 °C
The final results of the vapour pressure were derived from the regression of the results of the methods received by the dynamic and the effusions method (studies submitted under point 4.6 vapour pressure "k_Wielpütz_2007a" and "k_Wilepütz_2007b")
