The standardization of bullet resistance is not easy. There are different international standards for different bulletproof materials, but there are also different organizations that put forward their standard, European standards (EN 1063 BR and EN 1522 FB), NATO standards (STANAG 4569), American standards (NIJ).

​

​

We treat here costs the European standardEN 1522 FBbecause it applies to the BPT document trays that we offer.

​

TheEN 1522 FBis the standard for testing armored personnel carriersnon-transparentmaterials (eg joinery, steel plate and therefore also document drawers) TheEN 1063 BRis the standard for testing armored transparent materials (eg glass)
