- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Parameter:
- thermal sensitivity - Koenen test: diameter of the orifice plate
- Remarks on result:
- not thermal sensitive if heated under defined confinement
- Parameter:
- sensitiveness to impact: impact energy (J)
- Remarks on result:
- not sensitive to impact using an impact energy of 40 J
- Parameter:
- sensitiveness to friction: friction load (N)
- Remarks on result:
- not sensitive to friction using a friction load of 360 N
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Neodymium trinitrate was concluded not to be explosive when exposed to friction, shock or heat.
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 2.5 min, the test item overflowed, projections and sparks were observed. Between approx 3 and 4.5 min, smokes (2 assays) or a yellow flame of about 25-cm height (1 assay) was observed. Three assays using a tube with a hole of 2-mm diameter: between approx 2 and 3 min, the test item overflowed, projections and sparks were observed. Between approx 3 and 4 min, projections were observed. From approx 4 min to 4.5 min, smokes were observed (2 assays). In conclusion: six negative assays were recorded: No heat sensitivity was noted with the test item.
Description of key information
Neodymium trinitrate is concluded not to be explosive.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
An experimental study performed under GLP compliance and in accordance with EU A.14 method was flagged as a key study and assigned a Klimisch score of 1. It revealed that neodymium trinitrate is not sensitive to friction, shock or heat.
Justification for classification or non-classification
Neodymium trinitrate was tested not to have explosive properties and needs thus not to be classified for this endpoint according to CLP criteria.
