Windows and Pedestrian Doors - Mechanical Durability
Standard: EN 12400:2004
Standard Information
- Standard Number: EN 12400:2004
- Technical Committee: TC 169
- Status: Current
- Type: European Standard (EN)
EN 12400:2004 is the European standard that specifies the requirements and classifications for the mechanical durability of windows and pedestrian doors. It defines how many opening and closing cycles a door or window should withstand while maintaining its performance.
Classification System
The standard defines different classes based on the number of cycles:
For Doors
- Class 4: 50,000 cycles (Light use)
- Class 5: 100,000 cycles (Moderate use)
- Class 6: 200,000 cycles (Heavy use)
- Class 7: 500,000 cycles (Severe use)
- Class 8: 1,000,000 cycles (Extreme use)
For Windows
- Class 1: 5,000 cycles
- Class 2: 10,000 cycles
- Class 3: 20,000 cycles
Application Guidelines
Recommended Usage by Class
Doors:
- Class 4 (50,000): Private entrances, residential use
- Class 5 (100,000): Office buildings, light commercial use
- Class 6 (200,000): Shopping centers, heavy commercial use
- Class 7 (500,000): Public buildings, main entrances
- Class 8 (1,000,000): Airports, train stations, extreme usage
Windows:
- Class 1: Occasional use windows
- Class 2: Regular use windows
- Class 3: Frequent use windows
Testing Requirements
Testing procedures include:
- Complete opening and closing cycles
- Operation force measurements
- Function checks at intervals
- Final performance verification
- Component wear assessment
Performance Criteria
During and after testing, products must maintain:
- Smooth operation
- Operating forces within specified limits
- Structural integrity
- Weather sealing performance
- Security features functionality
Maintenance Considerations
- Regular inspection of moving parts
- Lubrication as per manufacturer specifications
- Adjustment of hardware when needed
- Replacement of worn components
- Documentation of maintenance activities
Factors Affecting Durability
- Environmental conditions
- Usage patterns
- Installation quality
- Maintenance regularity
- Door/window weight
- Hardware quality
Important Considerations:
- Select appropriate class for intended use
- Consider environmental factors
- Follow maintenance schedules
- Document all testing and maintenance
- Verify certification requirements
