RESULTS BAM FALLHAMMER

Preparation : Tested as received

SOP Reference : CTL SOP No. 413

Apparatus : BAM Fallhammer System 1

The sample was placed in the impact device and the 10 kg weight dropped from a height of 40 cm which is equivalent to 40 J. If an "explosion" was observed, the impact energy was reduced to 7.5 J and further tests conducted.

The sample was observed to exhibit no reaction at 40 J. 6 tests were performed. 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).

Interpretation of results:
GHS criteria not met
Conclusions:
Not sensitiveness of the substance to impact. Not thermal sensitive if heated under defined confinement.
Executive summary:

The study was performed in order to determine the explosive properties of test item according to EU A.14 guideline.

A Bam FallHammer test was performed to measure the sensitiveness of substances to impact. A series of six tests were performed dropping the 10 kg mass from 0.40 m (40 J). No explosion was oberved. No further tests were performed.

Koenen tube tests were performed to determine the effect of heating the substance in a steel tube, closed by orifice plates with differing diameters of hole, to determine whether the substance is liable to explode under conditions of intense heat and defined confinement. A series of three tests with a 6.0 mm diameter orifice plate was first performed and no explosions were obtained. Then a second series of three tests was performed with a 2.0 mm diameter orifice plate and no explosion were obtained.

Description of key information

Not sensitiveness of the substance to impact. Not thermal sensitive if heated under defined confinement.
