* Determined by extrapolation
Run 1: 10.8 g of sample was degassed for a 70 hour period. Starting vacuum pressure was 0.0063 mbar.
Run 2: 12.5 g of sample was degassed for a 94 hour period. Starting vacuum pressure was 0.0029 mbar.
Description of key information
A GLP-compliant study was performed to determine the vapour pressure according to EU Method A.4 without deviations (K1, Dekra, 2018). A vapour pressure of 8.5 Pa was determined at 20°C using the vapour pressure balance method.
Key value for chemical safety assessment
- Vapour pressure:
- 8.5 Pa
- at the temperature of:
- 20 °C
Additional information
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.
