For many years glass and glass/plastic combinations have been used in bullet resistant screens. Like anti bandit screens the whole structure has to withstand the attack. Multiple layers of glass and interlayer allows the glass to absorb the energy of the projectile and protect the required area. Glass is tested under the worse case conditions and assumes that the assailant aims square to the glass and can group the strikes in a tight pattern. In the design the ability to stop a bullet is easier than controlling the other related issues. The glass when hit is expected to break and flex. The flexing can cause particles of glass to flick off the rear pane. The spall of the back can be designed out but the new standard EN 1063 allows for both ns = no splinters and s = splinters. DARTZ use ONLY NS class glass, as S class glass is anycase dangerouse for those who are behind glass.

NIJ standard – National Institute of Justice standard
Ballistic protection levels / Ammunition types / Testing conditions.

The standards used by NIJ require the equipment to withstand 5 shots within 3 inches of each other and 2 inches from the side at all but one level.
The NIJ IV requires testing with a single shot.
