This European

23、 Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2009, and conflicting national standards shall be withdrawn at the latest by December 2009. Attention is drawn to the possibility that some of the elemen

24、ts 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 supersedes EN 115:1995. This document has been prepared under a mandate given to CEN by the European Commission and the European Free

25、 Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document. This standard is part of the EN 115 series of standards: “Safety of escalators and moving walks”. Consideri

26、ng that EN 115:1995 had given rise to requests for interpretation and this standard did not fully comply with EN 414 (today CEN Guide 414 “Safety of machinery - Rules for the drafting and presentation of safety standards“), CEN/TC 10 asked its working group 2 to revise EN 115:1995. This task was com

27、pleted by CEN/TC 10/WG 2 in 2007 by: taking into account the interpretations; taking over the agreed upon points from the work carried out by ISO/TC 178/WG 5; adapting the requirements to the state of the art using the risk assessment methodology as given in ISO/TS 14798:2006 1; improving the refere

28、nces to other standards according to the progress in that field; covering the requirements of CEN Guide 414 by creating a new structure which addresses the safety rules for the machine and provides requirements in the normative annexes and information in the informative annexes; increasing the measu

29、res against foreseeable misuse; reviewing the safety requirements for escalators and moving walks; discussing the comments arising from the CEN Enquiry. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Euro

30、pean Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United

31、 Kingdom. SANS 21-1:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .EN 115-1:2008 (E) 5 Introduction This standard is a Type C standard as stated in EN ISO 12100-1. The machinery concerned and the extent to which hazards, hazardous situat

32、ions and events are covered are indicated in the scope of this standard. When the provisions of this C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that hav

33、e been designed and built according to the provisions of this type C standard. The purpose of this standard is to define safety requirements for escalators and moving walks in order to safeguard people and objects against risks of accidents during installation, operation, maintenance and inspection

34、work. The contents of this standard are based on the assumption that persons using escalators and moving walks are able to do so unaided. However, physical and sensory abilities in a population can vary over a wide range, escalators and moving walks are also likely to be used by persons with a range

35、 of other disabilities. Some individuals, in particular older people, might have more than one impairment. Some individuals are not able to use an escalator or moving walk independently and rely on assistance/support being provided by a companion. Furthermore some individuals can be encumbered by ob

36、jects or be responsible for other persons, which can affect their mobility. The extent to which an individual is incapacitated by impairments and encumbrances often depends on the usability of products, facilities and the environment. The use of wheelchairs on escalators and moving walks can lead to

37、 dangerous situations which cannot be mitigated by machine designs and therefore should not be permitted. The use of lifts is the preferred method of vertical travel for most people with disabilities and in particular wheelchair users and persons with guide dogs. Additional signs should be provided

38、to indicate the location of other facilities, these facilities should be in close proximity to the escalators and moving walks and easy to find. It is assumed that negotiations have been made for each contract between the customer and the supplier/installer (see also Annex A) about: a) intended use

39、of the escalator or moving walk; b) environmental conditions; c) civil engineering problems; d) other aspects related to the place of installation. If escalators or moving walks are intended to be operated under special conditions, such as directly exposed to the weather or explosive atmosphere, or

40、in exceptional cases serve as emergency exits, appropriate design criteria, components, materials and instructions for use should be used that satisfy the particular conditions. An Interpretation Committee has been established to clarify, if necessary, the spirit in which the clauses of the standard

41、 have been drafted and to specify the requirements appropriate to particular cases. Interpretation Requests can be sent to the National Standard Bodies which will contact the responsible Technical Committee CEN/TC 10. The formats of an interpretation request and the interpretation are given in Annex

SANS 21-1:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .EN 115-1:2008 (E) 6 1 Scope 1.1 This standard is applicable for new escalators and moving walks (pallet or belt type) as defined in Clause 3. This standard deals with all signi

43、ficant hazards, hazardous situations and events relevant to escalators and moving walks when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). 1.2 This standard does not deal with hazards arising from seismic activities. 1.3

44、 This document is not applicable to escalators and moving walks which were manufactured before the date of its publication as EN. It is, however, recommended that existing installations be adapted to this standard. 2 Normative references The following referenced documents are indispensable for the a
