Results and discussion
Vapour pressure
- Temp.:
- 120 °C
- Vapour pressure:
- < 0 hPa
- Remarks on result:
- other: The test item showed an unusual behaviour of its vapour pressure, most likely caused by its heterogeneous nature. Therefore it can only be concluded that the vapour pressure is <1 * 10E-4 hPa up to 120 °C.
Transition / decomposition
- Transition / decomposition:
- no
- Transition temp.:
- > 450 °C

Applicant's summary and conclusion
- Conclusions:
- The test item showed an unusual behaviour of its vapour pressure, most likely caused by its heterogeneous nature. Therefore it can only be
concluded that the vapour pressure is <1 * 10E-4 hPa up to 120 °C. - Executive summary:
The vapour pressure of 308 AQN was assessed using the balance method, according to EU Guideline A.4 and OECD Guideline 104.
The test item showed an unusual behaviour of its vapour pressure, most likely caused by its heterogeneous nature. Therefore it can only be concluded that the vapour pressure is <1 * 10E-4 hPa up to 120 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
