This European Standard has been prepared by Technical Committee CEN/TC 129 “ Glass in building” the secretariat of which is held by IBN.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
The Main requirement for bullet-resistant glazing is to prevent the passage of projectiles from various types of weapon. The classification of bullet-resistance of glazing in this standard is a technical classification, based on common weapons and ammunition, in order of attacking power. As the variety of weapons and ammunition does not allow them all to be taken into account, a selection had to be made that covers most weapons and ammunition. The choice of bullet-resistant glazing is established by the user for each individual case.
This standard specifies performance requirements and test methods for the classification of the bullet-resistance of glass (consisting of one or more layer of glass) and glass/plastic composites.
NOTE 1: The term “bullet-resistant glazing” applies to products that have the obvious characteristics of glass, but it is understood to include also laminated products of glass and plastics.
This standard applies to:
NOTE 2: For interior use at a temperature of (18 ± 5) °C. For exterior use the influence of outside temperature and weathering should be considered. Any additional requirements should be agreed between the purchaser and the vendor.
NOTE 3: The protection provided by bullet-resistant glazing depends not only on the product itself, but also upon the design and fixing of the glass.

NOTE1: 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.
NOTE 2: Classes SG do not necessarily comply with the requirements specified in the classes BR, as the ammunition is different.
