Introduction

When it comes to protecting people, there can be no compromise in your building’s security precautions. In today’s world, we face increasing dangers of attack by intruders, shootings, and explosions in public spaces. Vetrotech’s glass solutions can resist such threats while meeting every building requirement to achieve seamless architectural integration.

To verify that a protective glazing solution can mitigate the impact of manual attacks, bullets, or blasts, it is crucial to test these solutions as part of a system: glass, but also the framing, anchorage, and other components. By testing the glazing system as a whole, it is possible to assess interaction between all of the components to better understand its performance.

Attack Class

ATTACK resistance – Protection against planned attacks and opportunistic damage such as intrusion and theft

Attack- or burglar-resistant glass is classified based on its ability to resist manual attacks by tools such as hammers, crowbars and power tools. Classifications are set by various international standards, including EN 356 and EN 1627-1630. These standards provide criteria for testing the resistance of a glazed system to different types of manual attacks. Glass tested to meet resistance classes P6B to P8B affords the highest levels of protection available from attack-resistant glass.

Bullet Class

BULLET resistance – Protection against firearms of various calibres, including handguns, rifles, and shotguns

Bullet-resistant glass (often referred to as “Bullet Proof”) is classified to a set of standardized levels of ballistic protection, from BR1 to BR7 (S&NS) + SG1 to SG2 (S&NS) as determined by the European standard EN 1063. Bullet-resistant systems, tested as per the system standard EN 1522 and EN 1523 are classified from Classes FB1 to FB7 (S/NS).These classes are used to evaluate the ability of a material or product to withstand penetration by different types of ammunition. The testing process involves firing multiple rounds of various calibres and velocities at the material or product from varying distances and angles.

Blast Class

BLAST resistance – Protection against satchel charges, car bombs, chemical explosives, and gas accidents

Blast-resistant glass is a specialized type of glass designed to withstand the dangers of explosions and other high-pressure events. The European standards EN 13541 classifies blast-resistant glass into four categories, ER1 to ER4 (S&NS), and EN13123-1/EN13124-1 classifies blast-resistant systems into EPR1 to EPR4 (S&NS) based on their ability to resist different levels of explosive pressure.
