EN 13123-2:2001 Outdoor Detonation Testing
The European standard for explosion resistance in windows and doors using outdoor detonation testing methods.

Blastproof Security Doors
Our range of blastproof security doors meets and exceeds EN 13123-2 standards for explosion resistance.
Overview
EN 13123-2:2001 specifies the requirements and classification for windows, doors, and shutters subjected to explosion pressure using outdoor detonation testing methods. This standard is part of a series that includes EN 13123-1 for shock tube testing.
Testing Methods
EN 13123-2 uses outdoor detonation testing to simulate real-world explosion scenarios. This method involves detonating a specific amount of TNT at a defined distance from the test specimen.
Outdoor Detonation Testing
- • Real-world explosion simulation
- • TNT equivalent measurements
- • Distance-based testing
- • Comprehensive blast effects
Test Parameters
- • TNT equivalent weight
- • Detonation distance
- • Pressure wave measurement
- • Fragment analysis
EXR Classification System
The EXR classification system indicates the level of explosion resistance based on outdoor detonation testing results. Each class represents protection against a specific TNT equivalent at a defined distance.
Classification Levels
- • EXR1: 3 kg TNT at 5 meters
- • EXR2: 5 kg TNT at 5 meters
- • EXR3: 10 kg TNT at 5 meters
- • EXR4: 20 kg TNT at 5 meters
- • EXR5: 30 kg TNT at 5 meters
Performance Requirements
- • Structural integrity
- • Fragment retention
- • Pressure wave resistance
- • Post-blast functionality
Components Tested
The standard covers various components of windows, doors, and shutters that are subjected to outdoor detonation testing.
Tested Elements
- • Door leaves and frames
- • Window sashes and frames
- • Shutter panels and guides
- • Hardware components
Performance Criteria
- • No penetration of fragments
- • Maintained structural integrity
- • Operational functionality
- • Safety requirements
Application Guidelines
Understanding the appropriate application of EN 13123-2 classified products is crucial for effective blast protection in real-world scenarios.
Selection Criteria
- • Risk assessment
- • Required protection level
- • Building type and location
- • Integration with other systems
Installation Requirements
- • Professional installation
- • Structural support
- • Integration with building envelope
- • Maintenance requirements
Safety Requirements
EN 13123-2 includes specific safety requirements to ensure the protection of building occupants during and after an explosion event.
Safety Features
- • Fragment retention
- • Egress capability
- • Emergency access
- • Post-blast safety
Compliance Requirements
- • Testing certification
- • Documentation requirements
- • Quality control measures
- • Regular maintenance
Important Note
EN 13123-2 (EXR classification) and EN 13123-1 (EXC classification) use different testing methods and are not directly comparable. The appropriate standard should be selected based on the specific requirements of the application and the type of explosion threat being addressed.
