Run 1 not reported due to the degassing period being deemed insufficient (21 hours).
Run 2 : 4.11 g of sample degassed for approximately 66 hours. Start vacuum 0.0014 mbar.
Run 3 : 4.26 g of sample degassed for approximately 91 hours. Start vacuum 0.0012 mbar.
The vapour pressure of the test item was determined to be 13.9 Pa at 20°C (mean of runs 2 and 3).
Description of key information
The vapour pressure of the test substance was determined to be 13.9 Pa at 20 °C using the static method according to EU Method A.4 in a GLP study (Dekra, 2018). This result was considered reliable without restrictions (K1).
Key value for chemical safety assessment
- Vapour pressure:
- 13.9 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.
