EN 12209 Building Hardware: Mechanical Mortise Lockcases & Follower Torques
Engineering Overview: Technical overview of European standard EN 12209, governing mechanical mortise lockcases and cylinder cam follower engagement forces.
Technical & Engineering Specifications
| Standard | European Harmonized Building Standard |
|---|---|
| Standard Reference | EN 12209:2016 (Mechanically Operated Locks and Latches) |
| Interfacing Component | DIN 30° Profile Cylinder Cam & Follower |
| Maximum Operating Torque | < 1.5 N.m under 1000 N lateral side load |
Lockcase & Cylinder System Harmony
While EN 1303 certifies the cylinder, EN 12209 certifies the mortise lockcase.
Key Interfacing Criteria
- Cam Torque Transmission: The cylinder cam must operate the lockcase deadbolt with $<1.5 ext{ N}\cdot ext{m}$ key torque.
- Side Load Latch Test: Lockcase latch and deadbolt must withstand $1000 ext{ N}$ lateral pressure without jamming the cylinder cam.
