Explosive properties UN class 1

In the test on explosive properties according to UN Transport Regulation, Test series 2,the test item showed no explosive properties.

According to the results of the test on thermal stability and explosive properties, the test item is classified as follows: test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation and CLP Regulation (EC 1272/2008) Annex 1: 2.1.

Interpretation of results:
other: not classified according to the CLP Regulation (EC 1272/2008)
Conclusions:
Non explosive.
Executive summary:

In DSC-measurements, test item showed an exothermic effect between 220 and 380 °C with an average energy release of -760 J/g.

As the energy of the exothermic decomposition was above the threshold of -500 J/g, further tests for explosive properties had to be performed.

As the energy of the exothermic decomposition was below the threshold of -800 J/g, series 1 type (a) and series 2 type (a) tests are not required.

In the test on explosive properties according to UN Transport Regulation, Test series 2, test item showed no explosive properties.

According to the results of the test on thermal stability and explosive properties, the test item is classified as follows:

UN Transport Regulation: test item does not have to be classified as explosive substance in class 1.

CLP Regulation (EC 1272/2008) Annex 1: 2.1: test item does not have to be classified as explosive substance.

Description of key information

Non explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

UN Transport Regulation, UN Test Series 2.

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008): Annex 1: 2.1, test item does not have to be classified as explosive substance, based on the results of the test on thermal stability (OECD 113) and explosive properties (UN Transport Regulation, Test Series 2).
