LIMITATION OF FORCES.
This is the crucial point of the standard.
 
CONTROL UNIT.
  

In respect of different types of "USERS" and different "ZONES" where the "MACHINE" can be installed, see on page "ZONE".

In case of the breakdown of the "MACHINE", a control unit has to be installed :

 
Beginning of the breakdown
To = 0 second

 
the "MACHINE" does not have to exert a force superior to 400 N
(1400 N in some cases)
 
T
d = 0,75 seconds

 
the force maximum exerted by the "MACHINE" has to be inferior to 150 N
( about 15 KG of pressure).
 
T
s = 5 secondes

 
the residual force maximum exerted by the "MACHINE" has to be inferior to 25 N
( about 2,5 KG of pressure).
The limitation of forces is resumed by this chart :


Depending on the kind of latch, this chart shows the dynamic acceptable forces,
during the first period To / Td of 0,75 seconds.

Dynamic forces tollerated

Type of movement of the door
 
Between the closing sides and the opposite sides
 
Gap of movement zone between 50 mm and 500 mm
Gap of movement superior to 500 mm
Between flat zones of a surface superior to 0.1 m, different from closing sides.² No side is smaller than 100 mm
Doors with orizontal movement
(Sliding portal)
400 N
1 400 N
1 400 N
Revolving door around a perpendicular axis on the ground
(2 hinged sections portal)
400 N
1 400 N
1 400 N
Doors with vertical movement
(Intersactions divided door)
400 N
400 N
1 400 N
Revolving door around a parallel axis on the ground
(centre hung side pivot door)
400 N
400 N
1 400 N
Lifting gates
(centre hung side pivot door)
400 N
400 N
1 400 N

The "INSTALLER" has to measure the forces of the "MACHINE" with a certified control unit.
He notes these results in the maintenance book of the machine and archives a copy.
In some cases a regular control every 6 months is necessary. (NF EN 13241-1. 5.1.1.6.f).
