Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 05 July 2012 - 09 July 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- GLP compliance:
- yes
- Type of method:
- effusion method: vapour pressure balance
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: V046212201
- Expiration date of the lot/batch: 30 April 2014
- Storage condition of test material: room temperature, in the dark - Test no.:
- #1
- Temp.:
- 25 °C
- Vapour pressure:
- 0.062 Pa
- Conclusions:
- The vapour pressure of the substance has been determined to be 6.2e-2 Pa at 25 deg C.
- Executive summary:
A total of ten runs were completed for the main sequence. Equilibrium with regard to vappor pressure was assessed to have been reached over the final nine runs. Thus, the final nine runs have been used to calculate the definitive vapour pressure value for the test item.
The method used and referenced in stated guidelines (EC A4 and OECD 104) is applicable to vapour pressure determinations. It is considered that the method chosen was the most suitable for the determination of vapour pressure for this test item.
