EN 13123-1:2001 Explosion Pressure Resistance
The European standard for explosion pressure resistance in windows and doors using shock tube testing methods.

Blastproof Security Doors
Our range of blastproof security doors meets and exceeds EN 13123-1 standards for explosion resistance.
Overview
EN 13123-1:2001 specifies the requirements and classification for windows, doors, and shutters subjected to explosion pressure using shock tube testing methods. This standard is part of a series that includes EN 13123-2 for outdoor detonation testing.
Testing Methods
EN 13123-1 uses shock tube testing to simulate blast waves in a controlled environment. This method allows for precise measurement of pressure and impulse effects on the test specimen.
Shock Tube Testing
- • Controlled environment testing
- • Precise pressure measurement
- • Repeatable test conditions
- • Safe testing procedure
Test Parameters
- • Pressure measurement
- • Impulse measurement
- • Deformation assessment
- • Post-test integrity check
EXC Classification System
The EXC classification system (EXC1 to EXC5) indicates the level of explosion resistance based on shock tube testing results. Each class represents a specific level of protection against blast waves.
Classification Levels
- • EXC1: Basic explosion resistance
- • EXC2: Enhanced protection
- • EXC3: High-level protection
- • EXC4: Very high protection
- • EXC5: Maximum protection
Performance Requirements
- • Structural integrity
- • Pressure resistance
- • Impulse resistance
- • Post-blast functionality
Components Tested
The standard covers various components of windows, doors, and shutters that are subjected to explosion pressure 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 13123-1 classified products is crucial for effective blast protection.
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 13123-1 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 13123-1 (EXC classification) and EN 13123-2 (EXR 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.
