Results and discussion

Vapour pressure
Key result
Temp.:
ca. 120 °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 120 °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 120 °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. One determination was conducted at 85°C and one at 120 °C.

The vapour pressure of the test item was considered to be lower than 10-3 Pa at 120 °C and as a consequence largely lower than 10-3 Pa at 20 °C.
