- Remarks on result:
- other: The test material did not change in appearance under the conditions used in the determination
- Conclusions:
- The vapour pressure of the test substance is 1.6 Pa at 25 deg. C. The test substance did not change in appearance under the conditions of the test.
- Executive summary:
The vapour pressure of the test substance was determined by a vapour pressure balance method according to EU Method A.4. Four replicate tests were performed. Temperature and pressure readings were taken between 5 and 15 deg. C. A plot of logPa vs. 1/K (reciprocal temperature) was constructed from experimental data from which the vapour pressure at 25 deg. C was extrapolated.
The test substance did not change in appearance under the conditions of the test.
The vapour pressure of the test substance, determined from the mean of 4 separate measurements is 1.60 Pa at 25 deg. C:
