Ballistic resistant glazing is being used more and more for public buildings. So how do testers determine the protection a security door or window will offer against a firearm?
Security doors, windows or partitions fitted with bullet-resistant glass have to undergo rigourous tests. Pass the tests and the subsequent certification is proof of the level of resistance the door, window or partition will provide.
In Europe, testing is carried out in accordance with EN standards. Other standards are used elsewhere – such as UL in the USA and BS in the UK – but EN is generally regarded as the benchmark.
Bullet-Resistance Test Video
This is a video of a ballistic resistance test carried out on a security door. It was filmed at a shooting laboratory under real-life certification conditions.
During the test, a trained and authorised shooter fires at both the glazing and frame to ensure that the bullet does not break through.
The level being tested determines the type of weapon and ammunition used as well as the distance from the target and speed of the bullet.
In this instance, a rifle is used to shoot at a DarTek security door – the test required for the European standard EN 1522, resistance class FB5.
