Interpretation of results:
Category 1 (strong oxidising solids) based on GHS criteria
Conclusions:
Rhodium trinitrate is a Category 1 oxidising solid.
Executive summary:

Michael-Schulz (2011) is an experimental study following UN method O1. It is not GLP-compliant but is otherwise adequate for assessment.

On the basis of the test results and according to the criteria specified in the Regulation (EC) No 1272/2008 (CLP-/GHS-Regulation) rhodium trinitrate is an oxidising solid of category 1.
