- other: (mean of 2 runs)
- Conclusions:
- Under the conditions of the study the vapour pressure of the test material was determined to be 108 Pa at 20°C (mean of runs 1 & 2).
- Executive summary:
The vapour pressure of the test material was determined in a GLP study which was conducted according to the standardised guidelines OECD 104 and EU Method A.4, using the static method. Under the conditions of the study the vapour pressure of the test material was determined to be 108 Pa at 20°C (mean of two runs).
