Categories: Performance: Glass

Principles

The bullet resistance of glass is its ability to resist the passage of projectiles. Additionally the glass may be required to have anti-spall behaviour such that particles are ejected from the non-attack face.

Glasses covering a wide range of performance are available reflecting the wide range of attack weapons.
 

Standards

EN 1063Glass in building - Security glazing - Testing and classification of resistance against bullet attack


 

Method of test

The method of test is described in EN 1063. If an IGU has a bullet resistant glass on the non-attack face then the properties of that glass may be accepted as the properties of the IGU.
 

Classification

There are nine classes of performance:

  • Classes SR1 to SR7 are for weapons firing bullets and are in ascending order of severity
  • Classes SG1 and SG2 are for shot guns in ascending order of severity
  • .
     

    CE Marking

    Most glazing products offer no bullet resistance performance and are marked npd.
