Ballistic Resistance of ARMOX Advance according to NATO standard AEP-55 STANAG 4569

Abstract ARMOX low-alloy high-strength steel sheet is used, among other things, as a basic homogeneous ballistic protection in plate carriers and vehicle bodies. The hardest armour plates of the series include Advance, which, even with smaller thickness, provides same stronger 500 or 600 sheets. manufacturer declares for Advance thickness 5 mm resistance to small arms fire 7.62x51 5.56x45 rounds according NATO AEP-55 STANAG 4569 Annex A level 1 7 7.62x39 API BZ 2. Due manufactured thicknesses, not specified levels 3 6 accordance A. For 3, does require test against flying fragments from 155 artillery shells, but it an optional component at discretion national authority. In order be able use this type purpose, empirical equations were used determine whether conditions set out Level 2 are met over full range required. From results obtained was found that shell therefore cannot alone bodies protective provide persons areas where expected.
