EN 1063 BR5 class testing of resistance against bullet attack

EN 1063 is a security glazing standard created by the European Committee for Standardization for measuring the protective strength of bullet-resistant glass. The abbreviation "BR" defined in the standard DIN EN 1063 is used for protection levels of transparent armor (bullet-proof glass) for armored cars. BR5 is also written as B5.

EN 1063 BR5 class test requirements for testing the bullet resistance of glazing: hand guns and rifles

*twist length (178 ± 10)mm
(a) FJ full copper alloy jacket
PB pointed bullet
SCP1 soft core (lead) and steel penetrator (type SS109)
Note: The classes BR1 ...BR7 are classified in order of the level of protection offered, e.g. a panel complying with the requirements specified for a certain class complies with those specified for the preceding classes.

EN 1063 is commonly used in conjunction with EN 1522 to form a ballistic classification system by which armored vehicles and structures are tested and rated. 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.
