Specific details on test material used for the study:
Batch No.: 465884
Purity: 100%
Parameter:
other: exothermic decomposition energy (J/g)
Value:
747
Remarks on result:
other: Exothermic decomposition of the test item was observed at an average temperature of 303.6℃.

With all experiments, a small endothermic peak between 100℃ and 175℃ was observed. It was due to melting of the test item. With the second experiment an artefact was observed before the melting peak. Since it is unknown what caused this effect and it was not observed in the first experiment, the result of Experiment 2 was discarded and an additional experiment was performed).


With all experiments, an exothermic decomposition effect starting at 250℃ was observed. The extrapolated onset temperature of the effect in the first experiment was 302.331℃. With the third and fourth experiment, the onset temperature of this effect was at 302.844℃ and 305.706℃, respectively. The exothermic decomposition energy was 807.36 J/g (first experiment), 843.41 J/g (third experiment) and 588.77 J/g (fourth experiment).


After the experiments, a black molten residue remained at the bottom of the sample container. It indicated melting and reaction and/or decomposition of the test item during the test.

Interpretation of results:
other: potential explosive
Conclusions:
Exothermic decomposition of the test item was observed at an average temperature of 303.6℃. The average exothermic decomposition energy was 747 J/g. According to this it was considered that the test item has potential explosive properties.
Executive summary:

The explosive properties of test item were evaluated using DSC based on OPPTS 830.6316.


Exothermic decomposition of the test item was observed at an average temperature of 303.6℃. The average exothermic decomposition energy was 747 J/g. According to this it was considered that the test item has potential explosive properties.

Additional information

Justification for classification or non-classification

Explosive screening test, USEPA OPPTS 830.6316: 


Exothermic decomposition of the test item was observed at an average temperature of 303.6℃. The average exothermic decomposition energy was 747 J/g.


Explosive main test: Not finished yet. Test results will be updated once available.


Based on the explosive screening test, the substance has potential explosive properties and the main test is not finished yet. Therefore, it is not possible to give a definite classification now.
