Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 April 2010- 06 July 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: United Nations (UN), UN no. ST/SG/AC.10/11/Rev.4: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Explosives of Class 3, Class 4, Division 5.1 and Class 9, Test O.1 , 2003.
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Test O.1 of UN-MTC Section 34 was performed with substance as received (decahydrate, white granules). Both the 1:1 and the 4:1 sample-to-cellulose ratio (by mass) exhibited a mean burning time more than the burning time of a 3:7 mixture (by mass) of potassium bromate and cellulose. Therefore it could be concluded that CN-Nitacal is not an oxidising substance.
Reference
Both the 1:1 and the 4:1 test substance/cellulose mixtures showed a mean burning time > than the burning time of the 3:7 reference substance/cellulose mixture.
Description of key information
UN Test O.1 was performed with substance as received (decahydrate, white granules). Both the 1:1 and the 4:1 sample-to-cellulose ratio (by mass) exhibited a mean burning time more than the burning time of a 3:7 mixture (by mass) of potassium bromate and cellulose. Therefore it could be concluded that CN-Nitacal is not an oxidising substance.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
UN 1454 (Calcium nitrate) -Special Provisions 34: The commercial grade of calcium nitrate fertilizer, when consisting mainly of a double salt (calcium nitrate and ammonium nitrate) containing not more than 10 percent ammonium nitrate and at least 12 percent water of crystallization, is not subject to the requirements of this subchapter.
Justification for classification or non-classification
Based on UN test results, nitric acid, ammonium calcium salt does not have to be classified according to the CLP Regulation for oxidising properties.
