- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The exothermic decomposition energy of the test item is 62 J/g. According to this it was considered that the test item has no explosive properties.
- Executive summary:
According to the screening procedures listed in Appendix 6 of UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating to explosives of Class 1, the exothermic decomposition temperature of the test item was determined by differential scanning calorimetry (GLP study). The exothermic decomposition energy and onset temperature of the exothermic decomposition of the test item were evaluated from the DSC curve. Under test conditions, the exothermic decomposition of the test item was observed at a temperature between 407.8°C and 447.4°C. The exothermic decomposition energy was 62 J/g. According to this it was considered that the test item has no explosive properties.
Reference
With the experiments, endothermic and exothermic effects were observed between 300°C and 550°C. With the first experiment one exothermic peak was observed. The extrapolated onset temperatures of the effect was 415.609°C. The exothermic decomposition energy was 76.479 J/g. With the second experiment two exothermic peaks were observed. The extrapolated onset temperatures of the effects were 406.808°C (first effect) and 467.932°C (second effect). The exothermic decomposition energy was 58.337 J/g (first effect) and 3.5342 J/g (second effect). With the third experiment two exothermic peaks were observed. The extrapolated onset temperatures of the effects were 401.136°C (first effect) and 426.913°C (second effect). The exothermic decomposition energy was 41.182 J/g (first effect) and 6.9157 J/g (second effect). Since multiple exothermic effects were observed during Experiment 2 and Experiment 3, the sum of the exothermic decomposition was determined (i.e. 61.872 J/g for Experiment 2 and 48.098 J/g for Experiment 3). The difference between the minimum and maximum exothermic decomposition energy is >10%, i.e. 59%. Since the exothermic decomposition energy is below 500 J/g, these results are accepted.
After the experiments, a white residue remained at the bottom of the sample container and the sample container had expanded. It indicated reaction and/or decomposition of the test item during the test.
Description of key information
Key study. Method according to UN Manual of Tests and Criteria Part I (appendix 6), GLP study. Under test conditions, the exothermic decomposition of the test item was observed at a temperature between 407.8°C and 447.4°C. The exothermic decomposition energy was 62 J/g. Therefore, it was considered that the test item has no explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive

Justification for classification or non-classification
Based on the available information, the substance is not classified for explosive properties according to CLP Regulation (EC) no. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
