Foreword
This document (EN 81-77:2013) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators
and moving walks”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by May 2014, and conflicting national standards shall be withdrawn at the
latest by May 2014.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This document is part of the EN 81 series of standards: “Safety rules for the construction and installation of
lifts”. This is the first edition of this European Standard.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech
Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
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.
The objective of this standard is to define additional safety rules related to passenger and goods/passenger-
lifts with a view to safeguarding persons and objects against the risks described below associated with the
use, maintenance, inspection and emergency operation of lifts subject to seismic conditions.
The aim of this European Standard is to:
— avoid loss of life and reduce the extent of injuries;
— avoid people trapped in the lift;
— avoid damage;
— avoid environmental problems related to oil leakage;
— reduce the number of lifts out of service.
It is assumed that negotiations have been made for each contract between the customer and the
supplier/installer about the design acceleration (a ) to be considered and the most effective position of the
d
seismic detection system, if any, and of the primary wave detection system, if any. The building designer or
the lift owner should provide the design acceleration (a ) which will be documented in the information for the
d
owner provided by the installer.
This European Standard covers only the effects of earthquakes and not the nature of them.
1 Scope
This European Standard specifies the special provisions and safety rules for passenger and goods passenger
lifts where these lifts are permanently installed in buildings that are in compliance with EN 1998-1
(Eurocode 8).
This standard defines additional requirements to EN 81-1 and EN 81-2.
It applies to new passenger lifts and goods passenger lifts. However, it may be used as a basis to improve the
safety of existing passenger and goods passenger lifts.
It does not apply to seismic lift category 0 as defined in Table A.1.
This European Standard does not address other risks due to seismic events (for example fire, flood,
explosion).
