Applicant's summary and conclusion
- Conclusions:
- Based on measurements, vapour pressures of 0.01 Pa at 20°C, 0.019 Pa at 25°C, and 0.36 Pa at 50°C were calculated.
- Executive summary:
The vapour pressure of the test item was investigated in a study conducted according to OECD Guideline 104 (Vapour Pressure Curve; 2006), EU Method A.4 (Vapour Pressure; 2008), and EPA OPPTS 830.7950 (Vapor Pressure; 1996) using the effusion method (Knudsen cell). Based on measured vapour pressures in the range of 20.3 to 50.7°C, vapour pressures at 20, 25, and 50°C were calculated using the Antoine equation. The calculation yielded vapour pressure values of 0.01 Pa at 20°C, 0.019 Pa at 25°C, and 0.3.6 Pa at 50°C.
