Any other information on results incl. tables
The regression of the results leads with a mean deviation of 5 % to the following equation:
In (p/hPa) =12.4749 - 2866.92/ (89.15+ t/°C)
The vapour pressures at 20°C and 50°C were calculated from the regression equation.
Temperature Vapour Pressure
20°C hPa 1.0*10 -6
50°C hPa 2.9.*10-4
In the temperature range used tor vapour pressure measurements the test item was solid.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
