Air Blast Doors Use Cases

Understanding when to use EN 13123-1 (Shock Tube) vs EN 13123-2 (Outdoor Detonation) testing standards for air blast doors.

Blastproof Security Doors

Our range of blastproof security doors meets both EN 13123-1 and EN 13123-2 standards for explosion resistance.

When EN 13123-2 is Appropriate for

High-Risk Scenarios

  • • Government buildings
  • • Data centers
  • • Military sites
  • • High-security facilities

Location Considerations

  • • External walls
  • • Corridors with blast risk
  • • Areas near building entrances
  • • High-traffic public spaces

EN 13123-2 provides strong evidence that a door can survive a real detonation, making it suitable for indoor use when the area could be subject to blast from a nearby device (e.g., a bomb smuggled into a lobby or hallway).

When EN 13123-1 (Shock Tube) is More Appropriate

Internal Blast Containment

  • • Laboratories
  • • Gas rooms
  • • Chemical plants
  • • Process industry facilities

Blast Characteristics

  • • Diffuse explosions
  • • Contained blasts
  • • Pressure duration focus
  • • Uniform pressure distribution

EN 13123-1 better simulates internal pressure waves, making it more relevant for process industry safety, laboratories, or equipment rooms where the focus is on pressure containment rather than fragmentation.

🔍 Bottom Line:
