Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 25 July 2008 to 07 November 2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted to GLP in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: vapour pressure balance
- Temp.:
- 25 °C
- Vapour pressure:
- 0 kPa
- Remarks on result:
- other: A mean of 5 runs
- Conclusions:
- Under the conditions of the study, the vapour pressure of the test material at 25 °C was found to be 3.9 x 10^-8 Pa.
- Executive summary:
The vapour pressure of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guideline EU Method A.4.
A total of 5 runs were performed in the test and the vapour pressure value is a mean of these values, based upon measurements and extrapolation.
Under the conditions of the study, the vapour pressure of the test material at 25 °C is 3.9 x 10^-08 Pa.

Additional information
The vapour pressure of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guideline EU Method A.4. The study was assigned a reliability score of 1 in line with the principles for assessing data quality as defined by Klimisch (1997).
A total of 5 runs were performed in the test and the vapour pressure value is a mean of these values, based upon measurements and extrapolation.
Under the conditions of the study, the vapour pressure of the test material at 25 °C is 3.9 x 10^-08 Pa.
