Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 May 2012 to 31 May 2012
- 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:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- 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:
- 0.13 Pa
- Conclusions:
- The vapour pressure of the test material was determined to be 1.3 x 10^-1 Pa at 25 °C.
- Executive summary:
The vapour pressure of the test material was determined in accordance with standardised guidelines OECD 104 and EU Method A.4, using the vapour pressure balance method. Under the conditions of the study, the vapour pressure of the test material was determined to be 1.3 x 10^-1 Pa at 25 °C.
Reference
The test material did not change in appearance under the conditions used in the determination.
A sequence of six runs was completed. The mean value of vapour pressure at 25 °C, extrapolated from the graphs of each run, was calculated. Subsequently, the vapour pressure of the test material was determined to be 1.3 x 10^-1 Pa at 25 °C.

Additional information
The vapour pressure of the test material was determined in accordance with standardised guidelines OECD 104 and EU Method A.4, using the vapour pressure balance method. Under the conditions of the study, the vapour pressure of the test material was determined to be 1.3 x 10^-1 Pa at 25 °C. The study was conducted to GLP and was assigned a reliability score of 1 in accordance with the criteria of Klimisch (1997) and considered suitable as an accurate reflection of the test material.
