Standards give security managers a clear frame of reference about the type and level of resistance a security door will provide. Here is a crash course on the standards to look out for.

Standards for security doors can be divided into four groups:

  • Manual attack resistance
  • Ballistic resistance
  • Fire resistance
  • Blast resistance

Manual Attack Resistance

The resistance a security door provides when attacked by an individual using an item, such as a baseball bat, or a tool, such as a drill.

EN 1627

EN 1627 classifies security doors from Class 1 to Class 6.

Class 3 and below is a basic level of resistance and is not typically used by sites which are at risk from manual attack.

Sites which have valuable property which is perceived to be at risk from theft, such as banks, jewellery stores, embassies or power plants, most commonly use Class 4 resistance security doors. High-risk sites, such as nuclear power plants, are starting to move up to Class 5.

This video shows the manual attack test for a Class 4 security door. 

 

Ballistic Resistance

The resistance a security door provides when attacked using a firearm like a pistol, rifle or shotgun.

EN 1522

EN 1522 classifies security doors from FB1 to FB7 including the FSG classification for shotguns.

Classifications are based on the mass of the bullet fired and a range of different weapons, calibres and ammunition are used when testing.

Fire Resistance

The resistance a security door provides against heat and the effects of burning.Security-doors-fire-resistance.jpg

EN 13501-2

EN 13501-2 tests a door’s capacity a) to obstruct the spread of a fire and b) to withstand exposure to fire.

EN 1634-1

EN 1634-1 uses a furnace test to expose a security door to increasing levels of heat and measures the duration of fire resistance the door provides.

Blast Resistance

The resistance a security door provides when attacked using explosives.

EN 13123/124-1

EN 13123/124-1 is a shock tube test which classifies security doors from EPR1 to EPR4. 

The resistance class is based on the force of the contained blast.

EN 13123/124-2

EN 13123/124-2 is an open air explosion test which classifies security doors from EXR1 to EXR5. 

The resistance class is based on the quantity of TNT used and the distance of the door from the blast.
