- Conclusions:
- The test item does not have to be classified as explosive in Class 1 according to the UN-Transport Regulations. The test item does not have to be classified as explosive according to GHS and EC 1272/2008 (CLP-Guideline) Annex 1:2.1. The test item has no explosive properties according to EC 440/2008, Part A, A.14.
- Executive summary:
It was tested whether the test item shows some effect on heating under confinement according to UN-Test series 1 (b) / 2 (b) (Koenen-Test), is sensitive to impact according to UN-Test series 3 (a) (ii) (BAM Fallhammer) or is sensitive to friction according to UN-Testseries 3 (b) (i) (BAM friction apparatus) (Class 1). The test item was negative in these tests. The test item is not explosive.

Time/pressure test with regard to UN test series C.1: assessment "No" (a pressure rise to 2070 kPa was not achieved).
Time/pressure test with regard to UN test series 1 (c) (i): assessment "-" (gauge pressure of 2070 kPa was not reached: substance did not show the ability to deflagrate).
Time/pressure test with regard to test series 2 (c) (i): assessment "-" (gauge pressure of 2070 kPa was not reached: substance showed no or slow deflagration).
Residual moisture:
The test item contains a residual moisture of 0.1 wt.%, which was determined by drying thetest item under vacuum.
Thermal stability (DSC):
In the temperature range from 280-290 °C an endothermic effect was observed, which leads straight into an exothermic effect from 290-360 °C, with an average decomposition energy of -700 J/g. Due to the decomposition energy being above 500 J/g, the main tests on explosive properties had to be carried out.
Heating under confinement: Koenen-Test UN-Test: 1 (b) / 2 (b)
Tests with orifice plates with 1.0 and 2.0 mm diameter orifice were performed.

The test item shows no reaction with either an orifice plate with a orifice-diameter of 1mm or 2 mm on heating under confinement. The result is considered "-". Due to the chemical structure and the physical state (pure solid) an explosion for an orificediameter of 6 mm can be excluded.
The Koenen-Test (UN-Test 1(b) / 2(b)) of the test item shows no effect an heating under confinement with an orifice plate with an orifice diameter of 1 or 2 mm. The assessment of the results with regard to test series 1 (b) was "-". The assessment of the results with regard to test series 2 (b) was "-".
Mechanical sensitivity: Friction: BAM Friction Apparatus UN-Test: 3 (b) (i)
No explosion was observed within 6 tests using a 360 N loading.
The assessment of the results with regard to test series 3 (b) (i) was "-".
Mechanical sensitivity: Impact: BAM Fallhammer UN-Test: 3 (a) (ii)
No explosion was observed within 6 tests dropping the 10 kg mass from 0.50 m (50 J).
The assessment of the results with regard to test series 3 (a) (ii) was "-".
Description of key information
It was tested whether the test item shows some effect on heating under confinement according to UN-Test series 1 (b) / 2 (b) (Koenen-Test), is sensitive to impact according to UN-Test series 3 (a) (ii) (BAM Fallhammer) or is sensitive to friction according to UN-Testseries 3 (b) (i) (BAM friction apparatus) (Class 1). The test item was negative in these tests. The test item is not explosive.
The UN time/pressure test (DIN EN ISO/IEC 17025, UN Transport Regulations ST/SG/AC.10/1 1/Rev.5, 2009) was performed with the test item. The test item did not show the ability to deflagrate.
