Remarks:

No reaction

Small-scale preliminary tests 2

Parameter:

sensitiveness to friction: friction load (N)

Remarks on result:

The results for BAM Fallhammer test were:

Mass (kg)	Height (m)	Test number and result						Comments
		1	2	3	4	5	6
10	0.4	x	x	x	x	x	x	No reaction observed

'x': denotes no reaction or decomposition (change in colour).

The test sample was observed to exhibit no reaction at 40 J. The test result is therefore considered negative (-) (according to the EC Classification, Packaging & Labelling of Dangerous Substances in the European Union Part 2, Testing Methods, Jan 97).

The results for BAM friction test were:

Mass (kg)	Height (m)	Test number and result						Comments
		1	2	3	4	5	6
8.34	360	x	x	x	x	x	x	Decomposition/discoloured black

'x': denotes no reaction or decomposition (change in colour)

The test sample was observed to exhibit no reaction at 360 N. The test result is therefore considered negative (-) (according to the EC Classification, Packaging & Labelling of Dangerous Substances in the European Union Part 2, Testing Methods, Jan 97).

The results for Koenen tube test were:

Mass of Sample (g)	Orifice Diameter (mm)	Time to First Ignition (s)	Explosion	Fragmentation type
27.60	6	54	x	O
27.60	6	56	x	A
27.60	6	58	x	O
27.60	2	49	x	A
27.60	2	48	x	O
27.60	2	46	x	O

'x': denotes fewer than 3 fragments

Fragmentation type O: tube unchanged

Fragmentation type A: bottom of tube bulged out

The sample did not exhibit an explosion during any of the tests. The test result is therefore considered negative.

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The results of the three tests, BAM Fallhammer, BAM Friction and Koenen Tube, were negative which is sufficient to conclude that the test item is not explosive.
