- Executive summary:
A study perfomed according to UN Test Series 1 and 2 (5th edition, 2009) was perfomed to determined the explosive properties of the test item. In UN Test A.1 the test item showed a positiv effect on the detonation. Time/pressure test UN Test 1 (c) (i) showed positiv results as well. Further test from UN Test series 2 - GAP test, Time/pressure test and Koenen test were perfomed. All three tests showed negative results. Following the flow chart logic in the UN Guideline and based on the observations and results it was concluded that the test item is not an explosive classified in class 1.

Time/pressure Test (UN-Test 1 (c) (i) and 2 (c) (i))
After confinement in the pressure-time
bomb, for pressure increase from 790 kPa to 2170 kPa times of 1072 ms,
912 ms and 720 ms were measured in three experiments.
Assessment
according to UN-Test 1 (c) (i): "+" (positive)
Assessment according to UN-Test 2 (c) (i): "-" (negative)
GAP-Test. UN-Test 2 (a)
1st attempt: 379.1 g of the test item were used. The steel tube was not fragmented. No hole was punched in the detection plate. Tube length obtained: 40.0 cm Approximately 95 % of the substance were preserved.
2nd attempt: 373.5 g of the test item were used. The steel tube was not fragmented. No hole was punched in the detection plate. Tube length obtained: 40.0 cm Approximately 95 % of the substance were preserved.
Assessment according to UN-Test 2 (a): "-" (negative)
Additional tests
Koenen test (nozzle opening 1.0 mm) (UN test 1 (b) and 2 (b)): negative, no explosive
2-inch steel tube (50 g booster) (UN test A.1): complete transmission of the detonation
Interpretation of the results
According to UN Test A.1 the test item should be regarded as explosive in class 1 for classification, which is the worst case. To determine the explosiveness of the test item in details UN Test series 2 were performed and the following observations and results led to the conclusion that the test item is not an explosive in class 1.

Additional information
A study perfomed according to UN Test Series 1 and 2 (5th edition, 2009) was perfomed to determined the explosive properties of the test item. In UN Test A.1 the test item showed a positiv effect on the detonation. Time/pressure test UN Test 1 (c) (i) showed positiv results as well. Further test from UN Test series 2 - GAP test, Time/pressure test and Koenen test were perfomed. All three tests showed negative results.

Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
In accordance with Annex I, Section 2.1 of Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EC) No 2017/776, and UN GHS Rev 6 (2015) the substance has to not be classified as explosive in class 1.
