25、eld 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of an identical text or by endorsement, at the latest by February 2015 and conflicting national standards shall be withdrawn at the latest by August 2017.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 possibilit
26、y 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 81-20:2014 supersedes EN 81-1:1998+A3:2009 and EN 81-2:1998+A3:2009. This document h
27、as 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. The content of this s
28、tandard provides the design rules, calculations, examinations and tests for lifts component, the requirements of which are specified in other EN 81 series of standards. Therefore this standard can only be used in conjunction with the standards for specific lift types, e.g. EN 81-20 for passenger and
29、 goods passenger lifts. This is the first edition of the standard. The need for replacement was based on the following points: improvement in safety due to changes in available technology; the need to reflect changes to the state of the art; incorporation of essential health and safety requirements
30、from the relevant EU Directives; elimination of obvious errors; incorporation of proposals resulting from interpretation requests1); improvement of the references to other standards according to the progress in that field. According to the CEN-CENELEC Internal Regulations, the national standards org
31、anizations 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
32、, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. 1) Within CEN/TC 10 an interpretation committee has been established to answer questions about the spirit in which the experts have drafted the various clauses of t
33、his standard. All such interpretations are published within CEN TS 81-11 until incorporated by amendment into the standards concerned. BS EN 81-50:2014EN 81-50:2014 (E) 5 Introduction The object of this standard is to define safety rules related to lifts with a view to safeguarding persons and objec
34、ts against the risk of accidents associated with the user-, maintenance- and emergency operation of lifts. Reference should be made to the respective introductions of the standards calling for the use of this standard with regard to persons and objects to be safeguarded, assumptions, principles, etc
