5、 pages 01.15 DIN EN 81-50:2015-02 2 A comma is used as the decimal marker. National foreword This standard includes safety requirements. This document (EN 81-50:2014) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators and moving walks” (Secretariat: AFNOR, France). The responsible

6、 German body involved in its preparation was the DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-33-01 AA Aufzge of Section Aufzge und Fahrtreppen. Representatives of manufacturers and users of lifts, and of the employers liability insuranc

7、e associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Lifts Directive”, Directive 95/16/EC, and which apply to lifts that are either first placed on the market or commis-sioned within the EEA. This standard se

8、rves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the

9、 Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Amendments This standard differs from DIN EN 81-1:2010-06 and DIN EN 81-2

10、:2010-08 as follows: a) requirements relating to the construction as specified in DIN EN 81-1:2010-06 and DIN EN 81-2:2010-08 have been deleted; b) test requirements specified in DIN EN 81-1:2010-06 and DIN EN 81-2:2010-08 have been included; c) safety has been improved due to changes in proven tech

11、nology; d) the standard has been revised to reflect changes to the state of the art; e) essential health and safety requirements set out in relevant EU Directives have been incorporated; f) reported errors have been eliminated; g) proposals resulting from interpretation requests have been incorporat

12、ed; h) references to other standards have been updated according to the progress in that field. Compared with DIN EN 81-50:2014-11, the following correction has been made to the German version only and therefore does not affect the English text: a) in Subclause 5.11.3 b), formula T2has been correcte

This European Standard shall b

34、e 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

35、 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 has been prepared under a mandate given to CE

36、N 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 standard provides the design rules, calculati

37、ons, 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 goods passenger lifts. This is the first ed

38、ition 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 from the relevant EU Directives; elimination

39、 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 organizations of the following countries are bo

40、und 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, Portug

41、al, 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 this standard. All such interpretations are p

42、ublished within CEN TS 81-11 until incorporated by amendment into the standards concerned.

43、ed 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. DINEN 81-50:2015-02EN 81-50:2014 (E) 6
