What are ballistic classes?

The European standard DIN EN 1522 defines the safety standards for bullet-resistant systems. Depending on the type of weapon, calibre, and test methodology, seven different ballistic resistance classes are distinguished. When testing glazing, the test result is complemented by either “S” for splintering or “NS” for non-splintering.

Ballistic resistance classes and their significance

The seven ballistic resistance classes of the European standard DIN EN 1522 are crucial for the classification of security systems. Each class specifies what type of threat the system protects against, ranging from small calibres to high-powered firearms. The classification is determined by rigorous tests in which the materials are examined for their bullet resistance.

Glazing and safety criteria

When testing glazing, not only bullet resistance is relevant but also the type of splintering. Glazing subjected to ballistic tests is categorised as “S” for splintering or “NS” for non-splintering. This distinction is important, as splinters in a threatening situation can pose additional risks of injury.

Secure solutions from SITEC

SITEC offers bullet-resistant systems up to the highest resistance class FB7. In the development of these systems, we ensure that all components are perfectly coordinated. This guarantees that the entire system meets the strict safety requirements of the European standard DIN EN 1522.
