Blast Attack Protection

Created by the European Committee for Standardization, the European Standard EN 13123/124-1 and EN 13123/124-2 are internationally recognized standards used to qualify the protection provided of security structures and products (complete with fillings and locks). To receive certification, products are independently tested on sites with companies such as Comblast in highly regulated environments to provide the level of protection requested. Safetell products have also been tested to ISO 16933.

In industries, to the actual need, i.e. 5 tons/m2 of 180 milliseconds (ms).

For risk of terrorist attacks, to an equivalent of 100kg of TNT at a given distance.
