Bullet resistance is required to protect life and is primarily used for personal and property protection. Examples include banks, security gates and embassies.
Bullet-resistant glazing provides resistance to the firing of certain handguns and their types of ammunition.
Examinations are conducted exclusively at shots, whose main tasks are the examination of handguns, their ammunition and shelling tests. Shooting Offices work together internationally according to the same standards.
Special laminated safety glass (VSG) is used which can withstand the fire and is colloquially referred to as bulletproof glass.
The glasses are classified according to the property “splitting” (S) and “non-splitting” (NS). Personal protection should always be fitted with non-shattering glass.
The basis of the glass tests are the standards DIN EN 356 and DIN EN 1063. The standards describe test methods and classification of the resistance to manual attack and fire. Often both claims are made simultaneously. For information on manual attack, see burglar resistance.
|Classification according to DIN EN 1063||Type of weapon||Caliber|
|BR 1||Rifle||22 LR|
|BR 2||Handgun||9mm Luger|
|BR 3||Handgun||.357 Magnum|
|BR 4||Handgun||.44 Rem. Magnum|
|BR 5||Rifle||5,56 x 45|
|BR 6||Rifle||7,62 x 51|
|BR 7||Rifle||7,62 x 51|
Bullet Resistant Glazing as
Curtain Wall Construction
The basis for the examination of windows, doors and shutters are the standards DIN EN 1522 and DIN EN 1523, to which curtain wall facades are assigned. The standards specify guns and calibers and describe requirements, classification and test methods as a fire test has to be done. There are 7 shelling classes. Similar to the glasses, the classes S (with splitter outlet) and NS (without splitter outlet) are evaluated, whereby frame materials and glass are tested.

Depending on the type of glass and construction, unilateral or bilateral attack is allowed during testing. A defined number of shots is fired at glass, frame construction and joints. In addition to vertically striking ammunition, shots are also fired at angles which are most unfavorable to the system. Joints are the most likely weak points, therefore, all building connections according to the selected class bullet-resistant perform.
