Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
According to ECHA's endpoint specific guidance R.7a (2013), vapour pressure testing is not required for a substance with a standard boiling point of < 30 ºC, as this substance will have a vapour pressure above the limit of measurement (i.e. 10E+05 Pa). The boiling point of ozone is –111.35 °C, hence no testing required. Ozone is a gas at the temperature of use. Nevertheless, a key value for chemical safety assessment is adopted from the online source PubChem, reporting a vapour pressure of 41257 mm Hg at 10.4 °C, which is equivalent to 55005 Pa at –12 °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.
