Any other information on results incl. tables
The vapour pressure are measured between 28 °C and 63 °C. The values at 20 °C, 25 °C and 50 °C are extrapolated from the measured values. The constants of Antoine Equation are A=12.92 and B=-3985.61.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC 440/2008 Method A.4. Vapour Pressure, OECD Test Guideline No. 104 (2006), and OCSPP Test Guideline 830.7950 (1996).
