The molecular structure of the test substance consists of no reactive groups that indicate a rapid decomposition. Besides, the test substance deliquesced when it was brought to the air for several minutes due to its hygroscopic behaviour.
Furthermore, it has been tested in a flammability test and was considered to be not highly flammable after flame ignition and it did not react violently.
Therefore no indication of any explosive properties is given.

Interpretation of results:

non explosive

Conclusions:

According to the expert statement, the test substance did not present any explosive properties.

Executive summary:

An expert statement evaluated the explosiveness of the test substance, C12-16 ADBAC (94.4% active) based on EU Method A.14. The molecular structure of the substance consisted of no reactive groups that indicate a rapid decomposition. In addition, the test substance deliquesced when it was brought to the air for several minutes, due to its hygroscopic behaviour. Furthermore, it has been tested in a flammability test and was considered to be not highly flammable after flame ignition and it did not react violently. According to the expert statement, the test substance did not present any explosive properties (Schulze, 2007).

other: expert statement on the test substance structure

Parameter:

other: expert statement

Remarks on result:

other: not oxidising

The test substance is a crystalline, but tenacious and sticky solid of white colour. Due to its hygroscopic behaviour, the test substance deliquesced when it is brought to the air for several minutes. According to the test guideline Directive 92/69/EC method A.10 (1992), 'Flammability of solids', the test substance is not highly flammable. During the flammability test, it was inflammable immediately by the hot flame of a gas burner. A spread out of the combustion zone over a distance of 100 mm in 96 seconds was observed after removal of the ignition flame. The combustion process was almost complete. Beside the properties mentioned above, test substance has no oxidising
potential under normal conditions. The molecular structure contains no oxygen. The test substance burns, but it has no oxidising properties.

Interpretation of results:

other: no oxidising properties

Conclusions:

According to the expert statement, the test substance did not present any oxidising properties.
