- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance was tested according to EU Method A.14.
According to DSC-test dynamic, the exothermal decomposition energy is ca. 281 J/g. It can be excluded that the tested substance has explosive properties. - Executive summary:
Method
Thermal stability of test substance was determined by DSC (Differential Scanning Calorimetry)
Results
Between 30 and 400 °C, the exothermal decomposition energy is about 281 J/g, thus below the limit of 500 J/g needed for classification as explosive.

Additional information
Justification for classification or non-classification
Based on the CLP Regulation (EC 1272/2008), substances, mixtures and articles are classified as unstable explosive on the basis of the flowchart in Figure 2.1.2 of the CLP Regulation. The test methods are described in Part I of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria.
Explosives, which are not classified as unstable explosives, shall be classified in one of the six divisions based on Test Series 2 to 8 in Part I of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria according to the results of the tests of explosiveness, sensitiveness and thermal stability, laid down in Table 2.1.1 of the CLP Regulation.
Based on the thermal analysis, in terms of decomposition temperature (below 400 °C) and energy (381 J/g), and known experience in handling and use, the substance is deemed not to be potentially explosive, therefore it is not classified.
In conclusion, the substance can be considered as non explosive, according to the CLP Regulation (EC 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
