In addition to the performance requirements in the face of multiple risks, it is essential to be able to guarantee the longevity of a construction element as essential as a door. In particular, it will be characterized by its frequency of use (endurance) and its impact resistance (mechanical resistance).
The objective is to guarantee the longevity of the door in the face of repeated opening/closing.
The NF EN 12400 standard specifies a classification method based on the performance of pedestrian doors when they are subjected to repeated opening and closing cycles. The classes take into account normal and intentional use.
For fire-resistant doors, the applicable standard is then EN 13501-2.
The EN 1191 standard defines the method to be used to carry out the repeated cycles of opening and closing the pedestrian door block and thus determine the endurance of the latter. The parts concerned by the test are the frame, the door leaf and all the necessary hardware, including the maneuvering devices. The standard specifies that at the end of the tests, the door unit must remain functional despite the maneuvering efforts to which it has been subjected. The test body must not have undergone any deterioration or deformation that would make the door unfit for use.
| Classification | Nombre de cycles | Utilisation | 
|---|---|---|
| Classe 1 | 5 000 | Occasionnelle | 
| Classe 2 | 10 000 | Faible | 
| Classe 3 | 20 000 | Peu fréquente | 
| Classe 4 | 50 000 | Modérée | 
| Classe 5 | 100 000 | Normale | 
| Classe 6 | 200 000 | Fréquente | 
| Classe 7 | 500 000 | Répétée | 
| Classe 8 | 1 000 000 | Très fréquente / Intensive | 
The objective is to guarantee the mechanical strength of a door or hatch in normal use.
The European standard EN 1192 “Doors — Classification of mechanical strength requirements” provides a reference framework for classifying the performance of leaves, frames, door units, according to their resistance to vertical load, static twisting, soft and heavy body impact and hard body impact. Special requirements, such as those concerning burglary resistance, are not included in this standard.
EN 947: Test method - Resistance to vertical load
EN 948: Test method - Torsion resistance
EN 949: Test method - Impact resistance of a soft and heavy body
EN 950: Test method - Impact resistance of a hard body
| Classe de résistance | Vertical load (N)  | Twist (N)  | Soft and heavy body shock (J)  | Hard body shock (J)  | 
|---|---|---|---|---|
| Classe 1 | 400 N | 200 | 30 | 1,5 | 
| Classe 2 | 600 N | 250 | 60 | 3 | 
| Classe 3 | 800 N | 300 | 120 | 5 | 
| Classe 4 | 1000 N | 350 | 180 | 8 |
