Description of key information

Considering the chemical structure of the substance and taking Appendix 6 of UN ‘Manual of Tests and Criteria’ for the use of screening procedures to assess oxidising substances, and the ECHA Endpoint specific guidance (R.7a) into consideration, the reference substance is considered not to contain any chemical groups indicating oxidising properties. Further testing was omitted and zirconium sulfate is concluded to be incapable of reacting exothermically with combustible materials.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Justification for classification or non-classification

Considering the chemical structure of the substance and taking Appendix 6 of UN ‘Manual of Tests and Criteria’ for the use of screening procedures to assess oxidising substances, and the ECHA Endpoint specific guidance (R.7a) into consideration, the reference substance is considered not to contain any chemical groups indicating oxidising properties. Zirconium sulfate is concluded to be incapable of reacting exothermically with combustible materials and needs thus not to be classified for this endpoint.
