Why is bullet resistance important?

In a world where safety is paramount, the bullet resistance of crucial importance. Thanks to the Euro Norm EN 1522, which has been valid throughout Europe since the end of 1998, all bullet-resistant materials, from doors to sliding troughs, are standardized.

Euro Norm EN 1522 and EN 1063

The Euro Norm EN 1522 applies to all bullet-resistant materials and determines the resistance classes from FB1 to FB7. This standard specifies how tests are carried out and what type of weapons and calibers should be used. For glazing, How object safety glass, is manufactured according to the Euro Norm EN 1063 tested, with the classes of BR1 to BR7 supplemented by S (with splitter outlet) or NS (without splitter outlet).

Use of object safety glass

object safety glass is an essential component of modern security solutions. It is integrated into windows and other glass surfaces to ensure the highest bullet resistance without sacrificing aesthetics.

Summary of resistance classes

The resistance classes for all bullet-resistant materials according to EN 1522 and EN 1063 are given as follows:

• FB1 to FB7 according to EN 1522 for different material types
• BR1 to BR7 for glazing according to EN 1063, each with the suffixes S or NS

In the exams for bullet resistance Attention is paid to whether material or glass splinters break off on the inside when fired.
