- Parameter:
- mean pressure rise time
- Result:
- 3.534 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No oxidising properties as the mean pressure rise time for the test material/cellulose mixture was slower than the mean pressure rise time for the nitric acid/cellulose mixtures.
- Executive summary:
This information is from a GLP compliant, guideline study and is considered suitable for assessment. Palladium dinitrate had no oxidising properties as the mean pressure rise time for the test material/cellulose mixture was slower than the mean pressure rise time for the nitric acid/cellulose mixtures.

Description of key information
Palladium (II) nitrate hydrate in solid form has oxidising properties as the mean burning time of the 4:1 sample-to-cellulose mixture (by mass) was lower than the mean burning time of the 3:2 mixture of the reference substance to cellulose. Palladium (II) nitrate hydrate is classified as Category 1 Oxidising Solid according to the Regulation (EC) No 1272/2008 (CLP) and GHS.
Key value for chemical safety assessment
- Oxidising properties:
- oxidising
Additional information
The study to determine oxidising properties of the solid form of Palladium (II) nitrate hydrate was performed according to UN-Test O.1 (Michael-Schulz 2016). The study is an unpublished guideline study that is reliable without restriction.
The mean burning time of the 4:1 sample-to-cellulose mixtures (by mass) was lower than the mean burning time R3 (13,8 s) of the 3:2 mixture (by mass) of potassium bromate to cellulose. Based on the test results, Palladium (II) nitrate hydrate fulfils the criteria of Class 5.1 “Oxidizing Substances”, packing group I of the TDG and of the Hazard Class “Oxidizing Solids”, category 1 of the Regulation (EC) No 1272/2008 (CLP) and GHS.
Supporting data is available for an aqueous solution of palladium dinitrate. Tremain (2007) is a GLP compliant study following EU method A.21 and is considered suitable for use as a supporting study for assessment of this endpoint for a solution of palladium dinitrate. Palladium dinitrate solution had no oxidising properties as the mean pressure rise time for the test material/cellulose mixture was slower than the mean pressure rise time for the nitric acid/cellulose mixtures.
Justification for classification or non-classification
Based on test results from a reliable study following UN method O.1 (Michael-Schulz 2016) Palladium (II) nitrate hydrate fulfils the criteria of Class 5.1 “Oxidizing Substances”, packing group I of the TDG and of the Hazard Class “Oxidizing Solids”, category 1 of the Regulation (EC) No 1272/2008 (CLP) and GHS.
