EN 1063 standard specifies performance requirements and test methods for the classification of resistance against bullet attack of glass (consisting of one or more layers of glass) and glass/plastic composites.
EN 1063 standard applies to attack by handguns, rifles and shotguns and glazing in buildings for interior and exterior use:
Handgun classes are EN 1063 BR2, EN 1063 BR3 and EN 1063 BR4,
Rifle specifications are EN 1063 BR1, EN 1063 BR5, EN 1063 BR6 and EN 1063 BR7.
Shotgun specs are EN 1063 SG1 and EN 1063 SG2.
BR7 class is the highest ballistic class in EN 1063, and it is also written as B7.

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.
The protection provided by bullet-resistant glazing depends not only on the product itself, but also upon the design and fixing of the glass.
