Bulletproof glass of a jeweler's window after a burglary attempt. The Mona Lisa behind bulletproof glass at the Louvre Museum. Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles, although, like any other material, it is not completely impenetrable.
EN 1063, or CEN 1063, is a security glazing standard created by the European Committee for Standardization for measuring the protective strength of bullet-resistant glass. It is commonly used in conjunction with EN 1522 (Euronorm standard for Bullet Resistance in Windows, Doors, Shutters and Blinds) to form a ballistic classification system by ...
Armor Level Protection PM 1.22 Long Rifle: This armor would protect against three hits, fired from 10±0.5 meters, of: 2.6±0.1 g (40±1.54 gr) .22 Long Rifle lead round-nose bullets at a velocity of 360±10 m/s (1181±33 ft/s) PM 2 9×19mm Parabellum: This armor would protect against three hits, fired from 5±0.5 meters, of:
The glass, which is much harder than plastic, flattens the bullet and thereby prevents penetration. This type of bullet-resistant glass is usually 70–75 mm (2.8–3.0 in) thick. Bullet-resistant glass constructed of laminated glass layers is built from glass sheets bonded together with polyvinyl butyral, polyurethane or ethylene-vinyl acetate.
For example, the U.S. National Institute of Justice standard 0104.04 for bullet-resistant vests specifies that a Type II vest must not deform clay representing the wearer's body when hit by an 8.0 g (124 gr) 9 mm caliber round nosed full-metal jacket bullet travelling at up to 358 m/s (1175 ft/s); but a Type IIIA vest is needed for protection ...
Lobby security upgrades were the highest-priority projects in the amended $40 million School Capital Fund for Buncombe County Schools.
Bullet-resistant glass, a type of laminated glass, is usually constructed using polycarbonate, thermoplastic materials, thermoset EVA, and layers of laminated glass. [20] In automobiles, the laminated glass panel is around 6.5 mm (0.26 inches) thick, in comparison to airplane glass being three times as thick. [21]
