Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:

- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.14 (Explosive properties)
- Deviations:
- no
- 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 I: Classification Procedures, Test Methods and Criteria Relating to Explosives of Class 1, Section 13: ¿Test Series 3¿, 2003.
- Deviations:
- no
- 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, Appendix 6: ¿Screening Procedures¿, 2003.

- Key result
- Parameter:
- other: Explosive (not specified)
- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a DSC screening test, no exothermic decomposition reactions above 500 J/g with a temperature onset lower than 500°C was observed. Therefore it is concluded that CN-Nitcal is not explosive.
Reference
In the DSC-curve of the first as well as the second experiment, an exothermic peak was observed between 300°C and 450°C.

Description of key information
In a DSC screening test, no exothermic decomposition reactions above 500 J/g with a temperature onset lower than 500°C was observed. Therefore it is concluded that CN-Nitcal is not explosive.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
Based on the available information, nitric acid, ammonium calcium salt does not need to be classified for the hazard 'Explosives'according to CLP Regulation (EC) No 1272/2008.
Based on structural features, relevant study results and on experience in handling, the substance does not have to be classified as a self-reactive substance.
