- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Remarks:
- No self-ignition was observed up to and including 420 °C.
- Conclusions:
- No self-ignition of cerium gadolinium oxide was observed up to and including 420 °C.
- Executive summary:
The relative self-ignition temperature of cerium gadolinium oxide was investigated in a GLP-compliant study according to EU A.16 method. The test substance was heated from room temperature to 420 °C at 0.5 °C/min in two successive assays. No self-ignition was observed.
Reference
At the start and at the end of the two assays, the test substance was a homogeneous white powder.
Description of key information
No self-ignition of cerium gadolinium oxide was observed up to and including 420 °C.
Key value for chemical safety assessment
Additional information
An experimental study performed under GLP compliance and in accordance with EU A.16 method was flagged as a key study and assigned a Klimisch score of 1. It reports that cerium gadolinium oxide does not self-ignite up to and including 420 °C.
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).
