- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- disregarded due to major methodological deficiencies
- Study period:
- 16 March 2018 to 11 December 2018
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- unsuitable test system
- Remarks:
- During the study an exotherm was seen that was attributed in the study report to the substance decomposing. However investigation by the registrant indicates that the exotherm is more likely due to the substance reacting with the test system in particular the crucible in which the substance is held during the test. As such it is considered appropriate to disregard the results of the study and conclude that it is scientifically not possible to conduct the study.
- Qualifier:
- according to guideline

- Value:

- Remarks on result:
- other: The exothermic decomposition energy was 517.2 J/g at 172.7 °C. According to this it was considered that the test material has potential explosive properties.
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- Under the conditions of the test exothermic decomposition of the test material was observed at a temperature of 172.7 °C. The exothermic decomposition energy was 517.2 J/g. According to this it was considered that the test material has potential explosive properties. During the study an exotherm was seen that was attributed in the study report to the substance decomposing. However investigation by the registrant indicates that the exotherm is more likely due to the substance reacting with the test system in particular the crucible in which the substance is held during the test.
As such it is considered appropriate to disregard the results of the study and conclude that it is scientifically not possible to conduct the study. - Executive summary:
The explosive properties of the test material were assessed according to UN Appendix 6: Screening Procedures and EPA Guideline OPPTS 830.6316 in accordance with the principles of GLP using differential scanning calorimetry.
During the first experiment, a small endothermic effect was observed between 100 °C and 125 °C due to a combination of melting and reaction and/or decomposition of the test material. Furthermore, an exothermic decomposition effect started at 125 °C. The exothermic decomposition energy could not be determined adequately during this first experiment since the sample pan ruptured disturbing the measurement. After experiment 1, a beige brown residue remained at the bottom of the sample container. The sample lid was opened due to pressure. It indicated reaction and/or decomposition of the test material during the test.
During experiment 2 and 3, a small endothermic peak between 75 °C and 150 °C was observed due to a combination of melting and reaction and/or decomposition of the test material. In both experiments, an exothermic decomposition effect starting at 150 °C was observed. The extrapolated onset temperature of the effect in experiment 2 was 167.095 °C. With experiment 3 an onset temperature of 178.216 °C was obtained. The exothermic decomposition energy was 518.93 J/g and 515.43 J/g respectively. After the experiments, a beige brown residue remained at the bottom of the sample container and some residue was observed at the outside of the sample lid. After the experiment, the sample container was swollen. It indicated reaction and/or decomposition of the test material during the test.
Under the conditions of the test exothermic decomposition of the test material was observed at a temperature of 172.7 °C. The exothermic decomposition energy was 517.2 J/g. It was therefore considered that the test material has potential explosive properties.
During the study an exotherm was seen that was attributed in the study report to the substance decomposing.

Additional information
The explosive properties of the test material were assessed according to UN Appendix 6: Screening Procedures and EPA Guideline OPPTS 830.6316 in accordance with the principles of GLP using differential scanning calorimetry. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as outlined by Klimisch et al. (1997).
During the first experiment, a small endothermic effect was observed between 100 °C and 125 °C due to a combination of melting and reaction and/or decomposition of the test material. Furthermore, an exothermic decomposition effect started at 125 °C. The exothermic decomposition energy could not be determined adequately during this first experiment since the sample pan ruptured disturbing the measurement. After experiment 1, a beige brown residue remained at the bottom of the sample container. The sample lid was opened due to pressure. It indicated reaction and/or decomposition of the test material during the test.

During the study an exotherm was seen that was attributed in the study report to the substance decomposing. However investigation by the registrant indicates that the exotherm is more likely due to the substance reacting with the test system in particular the crucible in which the substance is held during the test.

Justification for classification or non-classification
During the study an exotherm was seen that was attributed in the study report to the substance decomposing. However investigation by the registrant indicates that the exotherm is more likely due to the substance reacting with the test system in particular the crucible in which the substance is held during the test.
As such it is considered appropriate to disregard the results of the study and conclude that it is scientifically not possible to conduct the study.
Experience in use and handling of the substance by the registrant over a number of years indicate that the substance should not be classified as explosive.
