Glass in building. Bullet Resistant Glazing. Testing and classification of resistance against bullet attack.
BS EN1063 2000
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2000, and conflicting national standards shall be withdrawn at the latest by May 2000.
According to the CEN/CENELEC Internal Regulations, the national standards organizations o f the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Nether lands, 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:
- attack by handguns, rifles and shotguns;
- glazing in buildings, for interior and exterior use;
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.
- the glazing product itself, assuming proper fixing.
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.
