Applicant's summary and conclusion
- Conclusions:
- The isothermal TGA effusion method was applied for the determination of the vapour pressure of the substance, in accordance with OECD 104 (2006) and EU Method A.4 (2009) and according to GLP principles. The vapour pressure of the substance at 20°C (293K) and 25°C (298K) was 1.8 Pa and 3.2 Pa, respectively.
