Additional information

EU Method A.14

Justification for classification or non-classification

According to the CLP Regulation (EC) No 1272/2008, 2.1 section, an explosive substance or mixture is a solid or liquid substance or mixture of substances which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases.

On the basis of the results obtained in the screening test, performed in accordance with the EU method A.14, the substance can be considered as non-explosive.
