Reference
Friction test
Six negative assays were recorded: No friction sensitivity was noted with the test item with a loading of 360 Newtons. No further tests were performed.
Mechanical sensitivity (shock)
Six negative assays were recorded: No shock sensitivity was noted with the 40-J force.
No further tests were performed.
Heat sensitivity (flame)
Three assays using a tube with a hole of 6-mm diameter: between approx 2 and 3.5 min, the test item overflowed and a 20-cm height orange flame was observed (in 2 assays). The 20 -cm height orange flame in the 2 assays was observed until the end of the observation time (5 min).
Three assays using a tube with a hole of 2-mm diameter: between approx 2 and 2.5 min, the test item overflowed.
In conclusion: six negative assays were recorded: No heat sensitivity was noted with the test item.
Description of key information
Following a GLP study in accordance with EC test method A.14, praseodymium trinitrate is concluded not to be explosive (Ferron, 2012).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The experimental data show that praseodymium trinitrate is not sensitive to friction, shock or heat.
Justification for classification or non-classification
Based on a GLP study performed in accordance with EC test method A.14, praseodymium trinitrate was concluded not to have explosive properties. This results in an absence of classification under both DSD and CLP systems.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
