Description of key information
Platinum (II) nitrate 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. Platinum (II) nitrate is classified as Category 1 Oxidising Solid according to the Regulation (EC) No 1272/2008 (CLP) and GHS.Based on the test results, Platinum (II) nitrate fulfil 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.
Based on the test results, Platinum (II) nitrate fulfil 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.

Additional information
The study to determine oxidising properties of Platinum (II) nitrate 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 The study is an unpublished guideline study that is reliable without restriction.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, Platinum (II) nitrate 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.
Justification for classification or non-classification
Based on test results from a reliable study following UN method O.1 (Michael-Schulz 2016) Platinum (II) nitrate 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.
