Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with Column 2 of REACH Annex VII, information requirement 7.5, the vapour pressure study does not need to be conducted for substances which have a melting point greater than 300 °C. If the melting point is between 200°C and 300°C, a recognised calculation method is sufficient.
This substance decomposes before melting at 288 °C. EPI Suite does not include the element yttrium within its parameters and the EPI Suite predictions on inorganic substances are outside the estimation domain of the software. The calculation method outlined in the standardised guideline EU Method A.4 requires boiling point information as input data. As the substance decomposes before melting, boiling point information is not available on the substance.
It is therefore not considered possible to perform the calculation method for the substance. Furthermore, since the substance decomposes at a temnperature so close to the cut-off for waiving, it is considered justified to omit testing for this endpoint.

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.
