- UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating to explosives of Class 1
- Deviations:
- no
- Qualifier:

- Key result
- Parameter:
- other: Thermal stability
- Remarks on result:
- other: The energy of the exothermic decomposition of the test material was below the threshold of -500 J/g. This obviated the need for further tests on explosive properties of the test material.
- Interpretation of results:
- other: Not classified in accordance with EU Criteria.
- Conclusions:
- Under the conditions of this study in the DSC-measurement, the energy of the exothermic decomposition of the test material was below the threshold of -500 J/g. Therefore, further tests on explosive properties were not required.
- Executive summary:
The explosive properties of the test material were investigated in accordance with the standardised guidelines UN (Part I) and OECD 113.
Before the main test, a DSC-measurement in a closed glass crucible under nitrogen was performed up to a temperature of at least 500 °C to determine the thermal stability of the test material. In case the exothermal decomposition energy is below the threshold of -500 J/g, further tests do not need to be performed. Due to the fact that the strong exothermic effect could only be observed in the DSC measurement using an open aluminium crucible, it can be stated that this effect can be assigned to reaction with crucible material (aluminium) of the test material.
Under the conditions of this study in the DSC-measurement, the energy of the exothermic decomposition of the test material was below the threshold of -500 J/g. Therefore, further tests on explosive properties were not required.
Reference
- In the DSC runs PN 14225 and PN 14228 in closed glass crucibles the test material showed a small exothermic effect in the temperature range of 160 – 210 °C, with a maximum decomposition energy of -20 J/g. An endothermic effect was observed in in the temperature range of 310 – 370 °C. The course of the DSC signal from above 390 °C can be assigned to a pressure rise inside the crucible, due to the vapour pressure of the test material.
- In the DSC run PN 14481 in a closed gold plated stainless steel crucible the test material showed two exothermic effects in the temperature range of 130 – 240 °C and of 440 – 480 °C, with an overall decomposition energy of -30 J/g. An endothermic effect was observed in in the temperature range of 320 – 360 °C.
- In the DSC run PN 14482 in an open aluminium crucible, the test item showed an exothermic effect in the temperature range of 200 – 350 °C, with a decomposition energy of -800 J/g. An endothermic effect was observed in in the temperature range of 380 – 460 °C.
The results of the DSC-measurements are summarised in Table1.

- Due to the fact that the strong exothermic effect could only be observed in the DSC measurement using an open aluminium crucible, it can be stated that this effect can be assigned to reaction with crucible material (aluminium) of the test material. Due to the decomposition energy in closed glass and gold plated stainless steel crucibles being below the threshold of -500 J/g, further tests on explosive properties did not have to be performed.

Additional information
The explosive properties of the test material were investigated in accordance with the standardised guidelines UN (Part I) and OECD 113. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).
Before the main test, a DSC-measurement in a closed glass crucible under nitrogen was performed up to a temperature of at least 500 °C to determine the thermal stability of the test material. In case the exothermal decomposition energy is below the threshold of -500 J/g, further tests do not need to be performed. Due to the fact that the strong exothermic effect could only be observed in the DSC measurement using an open aluminium crucible, it can be stated that this effect can be assigned to reaction with crucible material (aluminium) of the test material.
Under the conditions of the study in the DSC-measurement, the energy of the exothermic decomposition of the test material was below the threshold of -500 J/g. Therefore, further tests on explosive properties were not required.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to explosive properties.
