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 ...
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 ...
Although the US military requirements for body armor mirror the NIJ's on a surface level, the two are very different systems. The two systems share a 44 mm (1.7 in) limit on back-face deformation, but SAPI-series plates increase linearly in protection (with each plate tested against the preceding plate's threats), and require a soft armor ...
Orlando Harris’ family pleaded with Missouri police to confiscate the 19-year-old’s bullet-proof vest, ammunition and AR-15-style rifle. They knew his mental health was fragile after more than ...

The Interceptor vest was tested to stop a 9×19mm 124-grain FMJ bullet at 1,400 feet per second (430 m/s) with minimal backface deformation, and it has a V-50 of roughly 1,525 feet per second (465 m/s). This means that the bullet in question must travel faster than 1,525 feet per second (465 m/s) for it to have more than a 50% chance of ...
