buffers for parapets: residual

[gil]

in the classic parapet (as from image below), the ntc establish the thrust that the handrail and therefore the vertical mounts, must bear. the norm lays down loads of 1, 2 or 3 kn (depending on cases) of thrust applied at the top. but the swab between a mountaineer and the other to which resistance constraints should be subjected?
absurdly, if I put a nice sturdy fit, with an equally robust handrail, according to what norm can I not swab them with a sheet of paper? How do I know that even the buffer has the right resistance? should they hold the same push as the handrail? If it were so 100% of the handrails I see would not be normal.

I suppose there is no specific norm but we have to do the calculations.
spoiler alert: I could say a festry, but I like to throw myself.. .
the norm should define in addition to the load of the mount even the maximum distance between one and the other. the more the mounts are far the more the bending of the buffer is large.
I therefore assume that in order to define the size of the buffer, the bending must be calculated according to the load bearable by the pillars and the distance between them.

Thank you for your contribution.
I do not understand that the standard establishes a maximum distance between the pillars. theoretically I could place them even at 10mt away, but at that point 2 solos should hold 2kn of push per meter, or 20kn. you should use profiles for large pillars and handrails and therefore you do not.

in the same way the norm speaks of push on the handrail (at the top of the parapet). therefore if the handrail and the pillars do not flench, neither the paper for the pad would flench, in this test. but it is evident that it would be blurred as soon as there is support.

I believe that the discrimanent its uni en 10807:1999 which defines the shock load tests.
practically run off a lot of sabbis against the buffering of the parapet and that if you sink it is not okay.
Does qulcuno know the norm in detail?

instead the uni en 14019:2004 is the similar norm for continuous facades.

But I would like to go further.

in the case of a railing are above all the anchors that must be taken into account.
There are software for calculating parapets. I don't know what criteria they work.
