For vehicles facing an abnormally high threat level, Hammerglass Ballistic Protection is available in protection classes BR4-NS (23 mm) and BR6-NS (39 mm) in accordance with standard EN 1063. We deliver primarily to the defence industry, embassies and people with high protection needs.
Ballistic resistant glass is certified in accordance with European Standard EN 1063. The various levels of protection are indicated by classes BR1 to BR7, where BR1 is the lowest protection class and BR7 the highest. The most common protection classes are BR4 and BR6. Hammerglass is tested by Beschussamt Ulm in Germany and certified as compliant with protection classes BR1-NS, BR4-NS and BR6-NS.
|BR1||The lowest ballistic protection class where a stronger glazing panel is tested with a light weapon caliber .22 LR. To pass the test, the panel must withstand 3 shots fired from a distance of 10 metres.|
|BR4||Ballistic protection class according to which the glazing panel is tested with a .44 Magnum revolver. To pass the test, the panel must withstand 3 shots fired from a distance of 5 metres.
|BR6||Higher ballistic protection class where a stronger glazing panel is tested with a high-speed weapon (automatic carbine) and 7.62x51 NATO ammunition (also known as .308 Winchester). To pass the test, the panel must withstand 3 shots fired from a distance of 10 metres.
|NS||The glazing panel meets the NS (No Splinter) class requirements if the inner glass layer is not broken in the test. NS classification means that no glass splinters or fragments enter the protected space in the event of gunfire.|
Hammerglass bullet resistant screens comprises a number of glass sheets laminated together with a Hammerglass sheet. This splinter-free solution is thinner and weighs considerably less than comparable glass-only solutions.
