Background

� The current standard is more than 13 years old and needed to be aligned with current safety requirements

� Needed to incorporate the result of studies of the Lift Industry on safety aspects, such as strength of the doors

Evolution of the “state of the art” for safety


www.palea.org4

Industry on safety aspects, such as strength of the doors and requirements for safety spaces

� Needed to align with the requirements of the Asia Pacific Region

Input to revision

� More than 80 CEN Interpretations on current edition

� Three amendments since 1998, A1 (PESSRAL), A2 (MRL) and A3 (UCM)

� Input from European interest groups, such as Trade


www.palea.org5

� Input from European interest groups, such as Trade Associations and the EU Commission

� Contribution and requests from non-European interest groups from PALEA, Asia Pacific and North America, etc.

� ISO/TC 178 work on harmonization of International standards

� New technologies and current state of the art

Revision outcome

� Clauses had to be renumbered – (Car doors and landing doors are now in the same section)

� Traction lifts and hydraulic lifts are now in the same document

� Clauses are supported by “formal” Risk Assessment

� Format is harmonised with current CEN & ISO standards


www.palea.org6

� Format is harmonised with current CEN & ISO standards

� Clauses are consolidated and redundancies are removed

� Overall user friendliness should be improved

International use

� EN 81-1 and EN 81-2 have wide acceptance around the world

� Accepted by many countries with or without national deviations

� Unique opportunity for


www.palea.org7

� Unique opportunity for harmonisation of regional codes and standards, resulting in

� Promoting and harmonizing the level of safety� Establishing common technical understanding for the entire profession� Improving the efficiency of the industry with benefits for all stakeholders

� To maintain such harmonization, close cooperation of National and International standardization organizations is essential

International Cooperation Group

� CEN/TC 10 Plenary in 2007, decided to extend the cooperation with the users of the EN standards outside Europe

� By applying ISO and CEN Cooperation agreement, and through ISO and CEN resolutions, ISO members were appointed to participate in the revision of standards
