Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

After the experiments, the sample container showed no changes and the residue appeared to be unchanged.

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.

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.
