Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Finished on 29 May 1995
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: UN Recommendations on the Transport of Dangerous Goods (Manual of Tests and Criteria, Third edition, 1995)
- Deviations:
- no
- Principles of method if other than guideline:
- Test described in the United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, third revised edition, test O.1: Test for oxidizing solids (section 34.4.1). Also known as the conical pile test.
- GLP compliance:
- no
- Contact with:
- other: sawdust or cellulose
- Sample tested:
- other: Reference substance
- Parameter:
- mean burning time
- Result:
- 195 s
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 106 s
- Sample tested:
- reference: 2:3 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 61 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Neodymium trinitrate gave a negative result according to the UN method in place in 1995 and a negative result according to the current method.
Neodymium trinitrate is not considered as an oxidizer.

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

The
mixture of neodymium trinitrate / cellulose in the ratio 4 / 1 does not
burn.
The
mixture of neodymium trinitrate / cellulose in the ratio 1 / 1 burns
with little flames. After the test,
there are
numerous incandescent spots within the pile. The burning times are
higher than those of the reference mixture.
Description of key information
Neodymium trinitrate gave a negative result according to the UN method in place in 1995 and a negative result according to the current method. Neodymium trinitrate is not considered to be an oxidizer.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
Neodymium trinitrate gave a negative result according to the UN method in place in 1995 and a negative result according to the current method.
