  The barriers of the industrial explosion series are intended mainly for oil and gas, petrochemical, chemical complex facilities, enterprises producing pyrotechnics and ammunition, large railway junctions. When assessing suppliers, require Test confirmation video!In order for the window to correspond to the class of VZ 50 GOST and P 57471, it must be tested by detonating at least 500 kg of TNT at a distance of not more than 30 meters. And with class VZ 28 - at least 500 kg of TNT at a distance of no more than 46 meters. The window after the explosion should not be broken. The test sample shall be larger than the product supplied or larger than 2600×2600.
