Results and discussion

Vapour pressure
Temp.:
25 °C
Vapour pressure:
< 0.004 Pa
Remarks on result:
other: The test material did not change in appearance under the conditions used in the determination.
Transition / decomposition
Transition / decomposition:
no

Any other information on results incl. tables

The test material has been determined to have a vapour pressure of less than 0.0041 Pa at 25 °C. No statistical analysis were performed because the balance readings were to low and variable for a line of best fit to have any meaning. Instead it was considered more appropriate to impose a regression slope on a choosen data point to provide an estimate of the maximum value for the vapour pressure at 25 °C.

Applicant's summary and conclusion

Conclusions:
The test material has been determined to have a vapour pressure of less than 0.0041 Pa at 25 °C.
Executive summary:

The vapour pressure was determined using a vapour pressure balance according to the EU-guideline.

The test material has been determined to have a vapour pressure of less than 0.0041 Pa at 25 °C.
