Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-08-07 - 2018-10-09
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- 23 Mar 2006
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- 24 Aug 2009
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- static method
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 690 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- 901 Pa
- Conclusions:
- From the measured values, the vapour pressure of the test item was calculated as 690 Pa at 20.0 °C and 901 Pa at 25 °C.
- Executive summary:
The vapour pressure of the test item was measured using the static method as described according to OECD 104 resp. EU A.4 and under GLP conditions. Ten pairs temperature/vapour pressure were used to calculate a regression from which vapour pressure at ambient temperature could be estimated.
From the measured values, the vapour pressure of the test item was calculated as 690 Pa at 20.0 °C and 901 Pa at 25 °C. The values of the heating and cooling down phase showed good correspondence.
Therefore, the result of the study is considered valid.
