EN 1063

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 which armored vehicles and structures are tested and rated.

[1] A similar classification system primarily used in the United States is NIJ Standard 0108, the U.S. National Institute of Justice's Standard for Ballistic Resistant Protective Materials which includes glass and armor plate.

The protective strength of a glazed shielding is rated based on the type of munitions, or threat level, it is capable of withstanding.

There are 7 main standard threat levels: BR1-BR7 (also written as B1-B7), each corresponding to a different type of small arms fire.

[3][4] The precise test requirements and bullet types used are as follows: LB - Lead Bullet FJ - Full Metal Jacket FN - Flat Nose RN - Round Nose CB - Cone Bullet PB - Pointed Bullet SC - Soft Core (lead) SCP - Soft Core (lead) & Steel Penetrator HC - Hard core, steel hardness > 63 HRC[5] This engineering-related article is a stub.
