Conclusions:

The vapour pressure of the test substance was 0.296 Pa at 25 °C using the vapour pressure balance method.

Executive summary:

The vapour pressure of the test substance registered was determined under GLP using a vapour pressure balance in accordance with EU Method A.4. A sample of the test substance was placed in the balance and a sequence of ten test runs was started after the sample had been under vacuum for about 4.5 hours. Each run was tested over a temperature range from 25 to 35 °C. Linear regression analysis was used to determine the vapour pressure of the substance at 25 °C. The average vapour pressure of the substance at 25 °C as determined in ten runs was 0.296 Pa. The test substance did not change in appearance under the test conditions.
