Ta dokument podaja dodatne zahteve in take, ki odstopajo od standarda EN 81-20, z namenom zagotavljanja varnosti uporabnikov dvigal in razpoložljivosti dvigal, ki se lahko uporabljajo za namene odpornosti proti vandalizmu. V drugih pogledih so takšna dvigala zasnovana v skladu s standardom EN 81-20. Ta dokument obravnava pomembne nevarnosti, nevarne razmere in dogodke, povezane z dvigali, na katere lahko vpliva vandalizem (kot je navedeno v točki 4), kadar se dvigala uporabljajo pod pogoji, ki jih je predvidel monter.
Ta standard ne obravnava varnosti objektov ali dvigal kategorije 0 (glej definicijo iz točke 3.2).
Ta standard je mogoče uporabljati kot osnovo za druge vrste dvigal, npr. nagnjena dvigala v skladu s standardom
EN 81-22.

Introduction

The lifts concerned and the extent to which hazards, hazardous situations and events are covered are

indicated in the scope of this document.
This document is a Type C standard as stated in EN ISO 12100.

When the provisions of this C standard are different from those which are stated in Type A or B

standards, the provisions of this document take precedence over the other standards, for lifts that

have been designed and built according to the provisions of this document.

This document provides guidance to the building designer, customer etc. and requirements for

design, where it is considered additional security or other measures may be required in order to

protect against the risk of vandalism. The customer will need to consider the extent of additional

protection required, as covered by the enclosed proposals, which may be adopted according to the

environment in which the lift installation is situated and the type of vandalism that is likely to be

experienced. Every lift is subject to some amount of careless or rough use. Lifts built to EN 81-20

offer a reasonable degree of protection against this and are referred to in this document as

Category 0. This document addresses additional protective measures against deliberate acts that

may result in equipment damage or injury to persons for lifts referred to in this document as Category

1 or Category 2.

With regard to potential hazards for vandalism the following factors are taken into consideration:

— degree of accessibility to the installation;
— the surrounding area;
— observation by others in the vicinity;
— extent of building security and surveillance of lift(s);
— period of access to the building, including the lift(s) (24 h);
— vulnerability of lift.

The clauses in this document apply to both Category 1 lifts and Category 2 lifts as defined in this

document (see Annex A) unless otherwise stated in the text.
The following assumptions were made whilst writing this document:
— the lift is designed to meet the basic requirements detailed in EN 81-20;

— the building and/or the lift structure are at least in accordance with the advice given in Annex A,

which form the basis of the negotiations outlined in EN 81-20:2014, 0.4.2;

— the lift, its well, landing and access areas, machinery spaces(s) and all associated equipment are

properly maintained in good, safe working order.

The forces exerted on the lift and its equipment will be as a result of manual effort or by item(s) such

as those defined in Annex E.

1 Scope

This document gives additional and deviating requirements to EN 81-20 as applicable in order to

ensure the safety of lift users and the availability of lifts, which may be used for vandal resistant

purposes. In all other respects such lifts are designed in accordance with EN 81-20. This document

deals with the significant hazards, hazardous situations and events relevant to lifts which can be

affected by vandalism (as listed in Clause 4) when they are used under the conditions as foreseen by

the installer.
It does not cover building security or Category 0 lifts (see definition 3.2).

For other types of lifts, e.g. inclined lifts according to EN 81-22, this standard can usefully be taken as

a basis.

distance shall be maintained back from the leading edge over a length of not less than 75 mm and

returned at an angle not exceeding 45° to the rear of the door panel. This return angle may be omitted

over a length not exceeding 200 mm at the top and/or bottom of the door panel to allow the fixing of
