Overview
editEN 1522 is standard that released by European Committee for Standardization to outlines the requirements and classifications for testing windows, doors, shutters, and blinds. Tests are conducted according to another standard (EN 1023).[1] EN 1522 applies to windows, doors, shutters, and blinds, including their frames and infills, to assess their resistance to attacks involving handguns, rifles, and shotguns. This standard can be used for classifying a protection level of armored vehicles, buildings or another type of armored structures.[2]
Protection Levels
editThe EN 1522 standard along with EN 1523 defines protection levels from FB1 to FB7, along with FSG, tailored to provide defense against handguns, rifles, and shotguns. The standard specifies weapon, bullet type, bullet mass, bullet strike velocity, testing distance and angle of attack for common ammunitions in the European market as below[3];
