Standard: EN 12217:2005
Standard Information
- Standard Number: EN 12217:2005
- Title: Doors - Operating forces - Requirements and classification
- Status: Current
- Application: Manually operated pedestrian doors
Classification System
Force Classes
The standard defines four classes based on operating forces:
- Class 0: No performance determined
- Class 1: Light operational forces (up to 75N)
- Class 2: Medium operational forces (up to 50N)
- Class 3: Light operational forces with door closer (up to 25N)
- Class 4: Very light operational forces (up to 10N)
Measurement Parameters
Forces are measured for:
- Initial opening force
- Maximum opening force
- Closing force
- Latching force
- Key/handle operation force
Testing Methods
Testing procedures include:
- Force measurement at different points
- Dynamic force testing
- Static force measurement
- Operating mechanism assessment
- Durability verification
Application Guidelines
Recommended Classes by Use
- Class 1: Standard residential doors
- Class 2: Public buildings, commercial use
- Class 3: Schools, hospitals, elderly care facilities
- Class 4: Accessible facilities, special needs applications
