Briefly, what does EN 12453 describe?
The EN 12453 Standard
describes in detail the types of risks of automatic doors and the solutions for user safety. The standard also establishes how to
carry out the crushing/impact tests with their physical limits of force, both for amplitude (N) and duration (s).
What are the obligations for the installer?
The provisions of European Directives and Standards make CE marking of motorised doors and gates compulsory. The
installer is obliged to draw up the Technical File which must contain: the Risk Analysis, the verifications of the Force
Measurements, the EC Declaration of Conformity, and finally, to affix the indelible CE mark on the motorised door.
How should the resulting graph be interpreted?
A) Impact - "Dynamic period": represents the development of the
force in the first moments of contact, and shows the energy
released at the moment of impact, related to the speed of the
movement and to
the mass of the gate; the measured parameters are:
-> Fd : maximum amplitude of force peak (N) depending on the type
of gate, it must be less than 400N or 1400N.
-> Td : duration of force peak (s), must be less than 0.75s.
B) Crushing - "Static period": represents the trend of the force after the initial contact. It shows the crushing generated by the
gate motor that insists on pushing even after impact; the measured parameters are:
-> Fs : is the average value of the static force, normally it should not exceed 150N.
C) Final Phase: - 5 seconds after initial contact, the residual force must remain at a level less than or equal to 25N, the graph
shall remain entirely within the coloured mask.
-> Fe : is the value of the final force, 5 seconds after the initial contact. Normally, the force should decrease until it is within a
maximum of 25N.
