Ballistic Standards have been prepared more than once for products that are currently bulletproof. Some of those NIJ (National Instıtute of Justice), NATO STANAG (Standardization Agreements) and European Standard (ISO EN).
NIJ, Despite being ballistic resistant, ballistic standards specify a minimum ballistic protection performance. 0101.04 (2001), NIJ 0101.06
and NIJ 0101.07 are used to determine the protection levels of pistols and rifles. NIJ 0115.00 (2000) focused on body threats and knives. NIJ 0108.01 (1985) Standard
shield, glass etc. Prepared for other ballistic protective materials.
NATO STANAG, It is a declaration that sets the ballistic standards of NATO member countries in the military field. All military equipment produced by NATO member countries must also comply with these standards. An example of STANAG is the STANAG magazine standard, which determines the bullet dimensions of STANAG's weapons. Many such standards have been introduced and these are called STANAG's (STANAGs).
European StandardEuropean Standard ISO EN 1522 and 1523 It covers the characteristics and classification of windows, doors, shutters and shutters.
European Standard ISO EN 1063covers the performance characteristics and test methods for the classification of the bullet resistance of glass (with one or more glass layers) and glass / plastic composites.
While determining the mentioned ballistic standards, first of all the class of the relevant product should be determined. In determining this class, products must be subjected to technical tests. These tests are carried out with predetermined shooting methods. As a result of the tests carried out with these shooting methods, the class of the product is determined. For example, FB7 for an armor steel door and BR6 for bulletproof glass.
According to EN 1063 or EN 1522/1523 ballistic standards, the product with a 500 mm x 500 mm glass frame or armor steel is fixed. Each sample takes 3 shots. The shot is made from a distance of 12 cm with each shot. The bullet angle should be 90 degrees, the shooting distance should be 5 m or 10 m depending on the resistance class. Bullets cannot penetrate bulletproof glasses and products with armor steel. If there are no particles in the protection layer (for glass), the ballistic class is categorized as NS = No Cleavage.
