Description of key information
On the basis of the test results and according to the criteria specified in the Regulation (EC) No 1272/2008 (CLP-/GHS-Regulation) ruthenium(IV)oxide is an oxidising solid of Category 2.
Key value for chemical safety assessment
- Oxidising properties:
- yes
Additional information
Michael-Schulz (2011) is a non-GLP study, following UN method O.1 and is considered to be adequate for assessment of this endpoint. On the basis of the test results and according to the criteria specified in the Regulation (EC) No 1272/2008 (CLP-/GHS-Regulation) ruthenium (IV) oxide is an oxidising solid of Category 2.
Justification for classification or non-classification
On the basis of the test results and according to the criteria specified in the Regulation (EC) No 1272/2008 (CLP-/GHS-Regulation) ruthenium-(IV)-oxide is an oxidising solid of Category 2.
