1. Thermal sensitivity:

- Method : Koenen test

- Results: jet diameter (mm) / start of reaction (s) / result

2 / 67* / no splints, barrell unchanged

2 / 68* / no splints, barrell unchanged

2 / 70* / no splints, barrell unchanged

6 / 60* / no splints, barrell unchanged

6 / 62* / no splints, barrell unchanged

6 / 60* / no splints, barrell unchanged

* total reaction time: 120 -125 s.

The test item is not explosive under the influence of heating (embedding).

2. Mechanical sensitivity:

- 1. Method: drop hammer

- Results: mass (kg) / height (cm) / total test / no reaction / partial decomposition / explosion

10 / 40 / 6 / 6 / 0 / 0

10 / 100 / 6 / 6 / 0 / 0

Results: 6 times negative. The test item was not sensitive to impact.

- 2. Method: BAM apparatus (friction)

- Parameters:

stress: 360 N

- Results: 6 times negative. The test item is not sensitive to friction.

Overall summary:

The test item is not explosive according to EC Regulation 84/449 EWG Test A14.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item was assessed for its explosive properties regarding sensitivity to heat, shock and friction. The results showed that the test item was not explosive.
Executive summary:

The test item was assessed for its explosive properties regarding sensitivity to heat, shock and friction in accordance to EU method A.14. The results showed that the test item was not explosive.

Description of key information

In a study the test item was assessed for its explosive properties regarding sensitivity to heat, shock and friction. Thus, the results showed that the test item was not explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The test item was assessed for its explosive properties regarding sensitivity to heat, shock and friction in accordance to EU method A.14. The results showed that the test item was not explosive.

Justification for classification or non-classification

Based on the results of the study assessing explosive properties and sensitivity to heat, shock and friction, the test item has not to be classified with respect to explosiveness.


Further, based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the twelfth time in Regulation (EU) 2019/521, the test item does not have to be classified with respect to explosiveness.
