Any other information on results incl. tables

Mechanical sensitivity by shock

A 10 kg mass was dropped from 0.4 meter height on the test substance and formed a solid pellet of it. Discolouration to light brown (original Colour: white) was observed in three of the six tests. This was probably due to decomposition under the released heat coming from the shock. In none of the tests, a vigorous reaction was observed nor had the cylinder burst open Spontaneously,

Mechanical sensitivity by friction

Exposing the test Substance to mechanical stress by friction did lead to a slight discolouration of the test substance. In all six tests, the colour of the test substance had changed from white into light brown, probably due to decomposition under the released heat coming from the friction between the two porcelain surfaces. In none of the tests a vigorous reaction was observed.


Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The determination of the mechanical sensitivity was performed in accordance with EECDirective 92/69 EEC, A. 14 "Explosive properties" (1992).
Exposing v123109 (CH03824) to mechanical stress by shock did not result in a vigorous reaction. Exposing V123109 (CH03824) to mechanical stress by friction did not result in a vigorous reaction.
From this it is concluded that v123109 (CH03824) is not explosive when exposed to mechanical stress (shock and friction).
