Compliant with EN 81-20/50 Dapa carried out the tests on all types of telescopic and central doors:

  • Lower (also for side frames over 150mm)
  • Parva
  • El120
  • E120
  • Ante vetrate

The same tests were carried out for the floor and cabin toe-guard even retractable

All the tests provide that they will be made with the mechanic constraint and without them (upper wheels and plastic shoes).

The EN 81-50 standard establishes that after the impact a deformation must not exceeding 120 mm. Dapa doors, due to their solidity, have never exceeded, after the impact, 40 mm of deformation on all types.

  1. They can have permanent deformations;
  2. There must be no loss of integrity of the door assembly. The door assembly must remain in place with no gaps greater than 0.12 m in the shaft;
  3. After the pendulum test the doors do not need to be able to function;
  4. There must be no cracks in the glass elements.



Dapa srl has concluded the adaptation to the new standards EN 81/20-81/50. These standards have entered on 1 September 2017 in place of the harmonised European standards EN 81-1/ and 2. The entire range of Dapa doors (Lower, Parva, Orbis, E 120, EI 120, Glass frame, Full-glass), has been subjected to tests that have established the correct constructive criterion, in compliance with the mechanical requirements of the standard, of the door as a whole. The structure used to support the tests, was created by Dapa srl. The notified body IMQ has certified compliance with all the requirements. The doors, in particular, to which we must add the tests on the floor and cabin paraments, in addition to frames exceeding 150 mm in width, have undergone during the tests a maximum deformation of 40 mm, compared to that provided by the maximum standard of 120 mm. The robustness and quality of the Dapa doors has therefore had a formal confirmation, as well as substantial. Dapa doors, in fact, ensure, beyond the reference standards, their absolute suitability to ensure the stability of the compartment where they are located. The regulatory/technical office has created a circular in which all the points in the legislation that affect automatisms and doors are identified, and is available, for any doubt, to clarify together the possible uncertainties
in the interpretation of these rules.
