Applicant's summary and conclusion
- Conclusions:
- The vapour pressure tests were performed at 32°C (305K) and at 40°C (313 K) with a 20 ml/min nitrogen flow rate.
Each test the traps (first and second ) were analysed separately. In all tests no test item was observed in the second traps.
Vapour pressure at 32°C: 3.86 x 10^-6 Pa
Vapour pressure at 40°C: 8.49 x 10^-6 Pa
A linear curve was obtained when reporting log P versus 1/T and was used to extrapolate the vapour pressure value at 20°C and 25°C:
Vapour pressure at 20°C: 1.09 x 10^-6 Pa
Vapour pressure at 25°C: 1.87 x 10^-6 Pa
