Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- JUSTIFICATION FOR DATA WAIVING
In accordance with section 1 of REACH Annex XI, the self-ignition temperature study (required in section 7.12 of Annex VII) is scientifically unjustified. The substance is an inorganic oxide in which the inorganic element is present in its highest possible oxidation state. Erbium (III) oxide is an inorganic oxide in which the inorganic element, Erbium, is in its highest possible oxidation state, +3. As such, it is incapable of further reaction with oxygen and thus can be designated as not self-igniting.

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.
