Results and discussion
Vapour pressure
- Key result
- Temp.:
- ca. 30 °C
- Vapour pressure:
- < 0.001 Pa
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- The vapour pressure of the test item was considered to be lower than 10-3 Pa at 30 °C and as a consequence largely lower than 10-3 Pa at 20 °C. This value of 10-3 Pa corresponds to the minimal limit of pressure determined by our apparatus.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item was considered to be lower than 10-3 Pa at 30 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
- Executive summary:
The vapour pressure of the test substance was measured according to OECD 104 / EU A4 guideline using a effusion method weight loss.
The vapour pressure of the test item was considered to be lower than 10-3 Pa at 30 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
