Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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:
- 2006
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- 1981
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- Deviations:
- no

- Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- < 0.21 Pa
- Test no.:
- #2
- Temp.:
- 25 °C
- Vapour pressure:
- < 0.21 Pa
- Test no.:
- #3
- Temp.:
- 50 °C
- Vapour pressure:
- < 0.21 Pa
- Conclusions:
- The test item showed no evaluable vapour pressure curve in the temperature range of 24 to 84°C. The vapour pressure for the temperatures 20, 25 and 50°C are estimated on the basis of the maximum measured vapour pressure, according to EU method A.4 and OECD guideline 104. The vapour presure is < 0.21 Pa at 20, 25 and 50 °C.
- Executive summary:
The test item showed no evaluable vapour pressure curve in the temperature range of 24 to 84°C. The vapour pressure for the temperatures 20, 25 and 50°C are estimated on the basis of the maximum measured vapour pressure, according to EU method A.4 and OECD guideline 104. The vapour presure is < 0.21 Pa at 20, 25 and 50°C.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
