Foreword
This document (EN 81-20:2014) 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text or by endorsement, at the latest by February 2015 and conflicting national standards shall be withdrawn
at the latest by August 2017.
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, in conjunction with EN 81-50:2014, supersedes EN 81-1:1998+A3:2009 and EN 81-
2:1998+A3:2009.
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 standard is the culmination of the progressive development of the EN standards for lifts. Previous
versions of the EN 81-1 and EN 81-2 standards incorporated into EN 81-20 and EN 81-50 include:
— EN 81-1:1985, Safety rules for electric lifts
— EN 81-1:1998, Safety rules for electric lifts
— EN 81-1:1998, Corrigendum No 1:1999;
— EN 81-1:1998/A1:2005, incorporating programmable electronic system in safety related applications for
lifts;
— EN 81-1:1998/A2:2004, incorporating machine-room-less lifts;
— EN 81-1:1998+A3:2009, Incorporating unintended car movement with open doors;
