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
