Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the substance at 20°C is below 4.6 x 10(-8) Pa
- Executive summary:
The vapour pressure of the substance was determined according to OECD 104 rsp. EU A.4 with the vapor pressure balance method.
For this purpose the vapour pressure was measured at 6 temperatures from 80 to 120°C. Out of these results the vapour pressures for lower temperatures
were calculated as follows:
20°C < 4.6 x 10(-8) Pa
25°C < 8.9 x 10(-8) Pa
50°C < 1.8 x 10(-6) Pa
