Reference
The data presented in the above field named 'Test results (Oxidising solids)' are those obtained during the test performed according to the current UN method.
1) Test according to the UN method in place in 1995:

No burning. The burning started when the flame was brought in contact with the pile, but stopped immediately after the cut off of the flame. An incomplete reaction was observed.

The lowest mean burning time obtained for the mixture praseodymium trinitrate/sawdust (ratio 1:1) is more than that of the mixture with ammonium persulphate. Therefore, praseodymium trinitrate is not considered as an oxidizing material according to the UN method in place in 1995.

The
mixture of praseodymium trinitrate / cellulose in the ratio 4 / 1 does
not burn.
The
mixture of praseodymium trinitrate / cellulose in the ratio 1 / 1 burns
with little flames.
All the burning times are higher than those of the reference mixture.
Description of key information
Lodel (1995) studied the oxidising properties of praseodymium trinitrate (99,9% crystallised) according to UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Third edition, 1995). The substance was observed not to be oxidising.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
Praseodymium trinitrate was tested not to have oxidising properties and needs thus not to be classified for this endpoint according to CLP criteria.
