Bunkerkit has been tested and certified in accordance with European ballistic protection standards EN 1522-1523. Its performance levels cover classes FB4, FB5, FB6, FB7 and AK47 Kalashnikov.
Bunkerkit holds the test reports drawn up by the laboratory of the Royal Military Academy of Belgium corresponding to the different classes tested.
The standards do not take account of the effect of rebounding bullets on the wall, which could cause other damage and constitute an uncontrolled threat. That is why Bunkerkit goes beyond these standards and is able to trap bullets inside the partition to prevent rebounding.
The Laboratory of the Royal Military Academy is the only body authorised in Belgium to carry out the tests according to the procedure required for certification. First of all, the impacts are directed at the centre of the panel to check the resistance of its intrinsic composition.
After this, the joints between the panels are tested.
The test report indicates whether there were any splinters (Splitting) or not (Non-Splitting) inside the secure zone. During the tests, an aluminium control sheet (0.02 mm thick) is placed inside the Bunkerkit (i.e. behind the samples tested) to detect all splinters which could come from the walls themselves.
Standard EN 1522-1523 comprises 7 ‘closed’ classes covering the munitions most commonly available on the European market. Classes FB1 to FB7 are ranked by increasing level of the protection provided. This means that a wall which meets the requirements defined for a given class also complies with the lower classes.
There are also other so-called ‘open’ classes. These classes cover munitions and calibres less commonly found in Europe. Bunkerkit has passed the tests for the open class ‘AK47’. These tests aim to check resistance to an attacking using a Kalashnikov, a weapon officially considered to be ‘uncommon’ as it is not widely sold in Europe, but which is in fact frequently used in armed attacks.
