Specific details on test material used for the study:
Batch No.: 472782
Purity: 99.8%
Parameter:
other: exothermic decomposition energy (J/g)
Value:
278
Remarks on result:
other: Exothermic decomposition of the test item was observed at an average temperature of 331.9℃.

With all experiments, a small endothermic peak between 225℃ and 275℃ was observed. It was due to melting of the test item.


With all experiments, an exothermic decomposition effect starting at 300℃ was observed. The extrapolated onset temperature of the effect in the first experiment was 330.732℃. With the second and third experiment, the onset temperature of this effect was at 332.765℃ and 332.274℃, respectively. The exothermic decomposition energy was 210.53 J/g (first experiment), 263.08 J/g (second experiment) and 361.34 J/g (third experiment).


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

Interpretation of results:
GHS criteria not met
Conclusions:
Exothermic decomposition of the test item was observed at an average temperature of 331.9℃. The average exothermic decomposition energy was 278 J/g. According to this it was considered that the test item has no 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 331.9℃. The average exothermic decomposition energy was 278 J/g. According to this it was considered that the test item has no 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 331.9℃. The average exothermic decomposition energy was 278 J/g.


In accordance with Regulation (EC) No. 1272/2008 section 2.1.4.3 (c), a substance or mixture shall not be classified as explosive when the organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 ℃. Therefore the substance shall not be classified as explosive.
