- In the DSC-measurement the energy of the exothermic decomposition of the test item was potentially above the threshold of -500 J/g. Therefore, further tests for explosive properties had to be performed.
In the test on explosive properties according to UN Transport Regulation, Test series 1 and 2, the test item showed no explosive properties. - Executive summary:
In the DSC-measurement the energy of the exothermic decomposition of the test item was potentially above the threshold of -500 J/g. Therefore, further tests for explosive properties had to be performed.
In the test on explosive properties according to UN Transport Regulation, Test series 1 and 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 following:
UN Transport Regulation: The test item does not have to be classified as explosive substance in class 1 according to the UN Transport Regulation.
GHS (CLP Regulation EC 1272/2008: Annex 1: 2.1): The test item does not have to be classified as explosive substance according to GHS or CLP Regulation EC 1272/2008 Annex 1: 2.1, respectively.
This study was GLP compliant and followed UN Recommendations on the Transport of Dangerous Goods:
Manual of Tests and Criteria, Rev. 6 (2015) andUN-Model Regulations, Rev. 20 (2017). The study was given a reliability rating of 1 (reliable without restrictions).
Reference
The DSC runs PN14350, PN14357 and PN14423 in a closed glass or gold-plated stainless steel crucible are shown in the table below.
In the measurements using a glass crucible no significant thermal effects could be observed due to the strong noise of the DSC signal. For this reason an additional measurement in a gold plated stainless steel crucible up to a temperature of 500 °C was performed. Starting at a temperature of 350 °C anexothermic effect with a decomposition energy of >-440 J/g was observed. Because of the test end at 500 °C the exothermic effect was not fully recorded and the associated energy release cannot be fully quantified. Because of the shape of the signal an energy release of >-500 J/g has to be assumed.
The results of the DSC-measurements are summarized in Table 1.

Due to the fact that the decomposition energy is above the threshold of -500 J/g the Koenen- and the Time-Pressure-Test had to be performed.
Three tests with a 1.0 mm diameter orifice plate were performed.

Due to the fact that the test series with a1.0 mm diameter orifice plate showed no explosionthe UN-Transport Regulation Test 1(b) and Test 2(b) deemed to be “–“.

Due to the fact that the test item did not reach a pressure of 2070 kPa,the UN-Transport Regulation Test 1(c) and 2(c) deemed to be “-“.
Description of key information
In the DSC-measurement the energy of the exothermic decomposition of the test item was potentially above the threshold of -500 J/g. Therefore, further tests for explosive properties had to be performed.
In the test on explosive properties according to UN Transport Regulation, Test series 1 and 2, the test item showed no explosive properties.

Justification for classification or non-classification
In the DSC-measurement the energy of the exothermic decomposition of the test item was potentially above the threshold of -500 J/g. Therefore, further tests for explosive properties had to be performed. In the test on explosive properties according to UN Transport Regulation, Test series 1 and 2, the test item showed no explosive properties.
This study was GLP compliant and given a reliability rating of 1 (reliable without restrictions).
