Mechanical sensitivity (impact) EC A.14.; UN Series 3, Test 3 (a) (ii): BAM Fallhammer (drop hammer)<\/h1>\n

The test consists of subjecting the test substance to the impact of a specified drop-weight from a specified height.<\/h2>\n

The essential parts of the fallhammer are the cast steel block with base, the anvil, the column, the guides, the drop weights with release device and the impact device. The steel anvil (100 mm diameter \u00d7 70 mm height) is screwed onto the top of a steel block (230 mm length \u00d7 250 mm width \u00d7 200 mm height) with a base (450 mm length \u00d7 450 mm width \u00d7 60 mm height). A column of seamless drawn steel tubing is fixed in a bracket that is bolted to the back of the steel block. The fallhammer is fixed with 4 anchoring screws on a solid concrete block (60 cm \u00d7 60 cm) in such a way that the guides are exactly vertical and the drop weight is easily guided. Drop weights are made of solid steel and are available, for example, in 5 kg and 10 kg weights. The striking head of each weight is made of hardened steel, HRC 60 to 63, and has a minimum diameter of 25 mm.<\/p>\n

The test result is assessed as positive if an explosion (a bang and\/or ignition is equivalent to an explosion) occurs with the apparatus described in at least one test.[\/vc_column_text][vc_row_inner rt_row_style=”global-style” rt_bg_custom_alignment=”top” class=”test__illustration–desktop”][vc_column_inner width=”1\/2″ rt_column_shadow=”” rt_bg_image_repeat=”repeat” rt_bg_size=”auto auto” rt_bg_attachment=”scroll”][vc_single_image image=”10922″ img_size=”full” add_caption=”yes”][vc_column_text](1)\u00a0\u00a0\u00a0 Base, 450 x 450 x 60<\/p>\n
