BALLISTIC TESTS
There are two main standards: The EN 1522 standard for windows, doors, shutters and blinds defines 7 resistance levels for pistols, rifles and assault rifles (from FB1 to FB7) and for shotguns (FSG). The EN 1963 standard for security glazing specifies 7 resistance levels for pistols, and for pistols and rifles (from BR1 to BR7) and 2 resistance levels for shotguns (SG1 and SG2). If the level numbers are followed by an “S”, it means the security glazing failed the projection test (with splinters). If they are followed by an “NS”, it means the glazing passed the test (without splinters).
