Parameter:

other: thermal behaviour

Remarks on result:

other: the substance decomposes at temperature lower than 500 °C, with an energy less than 500 J/g

The test item showed an endothermic effect starting at a temperature of 220 °C. A first exothermic effect was observed starting at 280 °C with an average energy release of -290 J/g. A second exothermic was observed starting at 430 °C with an average energy release of -40 J/g. The test item started to decompose at approx. 280 °C.

Sample weight / mg	Start of effect / °C	Energy / J/g
8.85	220	+40 (endothermic)
	280	-290 (exothermic)
	430	-50 (exothermic)
11.48	220	+30 (endothermic)
	280	-280 (exothermic)
	430	-20 (exothermic)

Interpretation of results:

other: not classified, according to the CLP Regulation (EC) No 1272/2008

Conclusions:

The substance decomposes at temperature lower than 500 °C, with an energy less than 500 J/g

Executive summary:

The determination of the thermal stability of a substance was performed via Differential Scanning Calorimetry (DSC). The prepared crucibles (crucible with test item and reference crucible) are placed in the DSC apparatus. Both crucibles are heated up from room temperature to 500 °C with a heating rate of 3 K/min. For the determination of the thermal stability, two investigations were performed. The evaluation of the data was performed by the software STARe.

The test item showed an endothermic effect starting at a temperature of 220 °C. A first exothermic effect was observed starting at 280 °C with an average energy release of -290 J/g. A second exothermic was observed starting at 430 °C with an average energy release of -40 J/g. The test item started to decompose at approx. 280 °C.

Conclusion

The substance decomposes at temperature lower than 500 °C, with an energy less than 500 J/g

Description of key information

Non explosive

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

The substance decomposes at temperature lower than 500 °C, with an energy less than 500 J/g.

Justification for classification or non-classification

According to the CLP Regulation (EC) No 1272/2008, 2.1.4.2. Screening procedure section, the screening procedure is aimed at identifying the presence of such reactive groups and the potential for rapid energy release. If the screening procedure identifies the substance or mixture to be a potential explosive, the acceptance procedure (section 10.3 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria) has to be performed.

Screening procedure failed to evidence any reason for concern because the substance decomposes at temperature lower than 500 °C, with an energy less than 500 J/g.

In conclusion, the substance meets the screening criteria, on the basis of which a substance shall not be classified as explosive, according to the CLP Regulation (EC) No 1272/2008.
