Bulletproof glass NATO STANAG 4569 AEP - 55
Level 2 and Level 3
The bulletproof glass is a transparent
composite product.
It is a stratified object composed of
various transparent sheets of glass alternating with
layers of polycarbonate glued by means of a particular
cycle of high pressure, vacuum and temperature in the
autoclave.
The careful choice of materials, the
provision of various thicknesses, the timing of different
transparent layers and the production cycle are the
prerequisite to obtaining the maximum protection that will
withstand the most devastating impacts of penetrating
projectiles of war described in the relevant NATO
standards.
The STANAG bulletproof glass, transparent
and monolithic withstand armor-piercing war mmx51mm
caliber 7.62 AP (WC core) with hard tungsten core.
The legislation STANAG 4569 AEP 55 Level 3
or Level 2 requires that the specimen of glass can
withstand the impact of three 7.62 caliber bullets mmx51mm
AP (WC Core) shot on target from a distance of 10m. The
three bullets have hit at the vertices of an equilateral
triangle of 120mm from the side.
The certification requires three identical
specimens withstand the full test.
