Applicant's summary and conclusion
- Conclusions:
- 8.2 × 10-33 Pa at 25 °C
- Executive summary:
The estimation of the vapour pressure of the test item was based on the EEC directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.4 'Vapour Pressure", EEC Publication No. L383, December 1992 and the OECD Guideline No. 104,
'Vapour Pressure", adopted July 27, 1995.
The boiling point of the test substance was calculated to be approximately 902 °C using Meissner's method
The vapour pressure of the test material was estimated to be 8.2 × 10-33 Pa at 25 °C based on the boiling point calculated and using the Modified Watson Correlation.
