National foreword This South African standard was approv

20、ed by National Committee StanSA SC 5120.50B, Lifts, escalators and passenger conveyors Lifts other than domestic lifts, in accordance with procedures of Standards South Africa, in compliance with annex 3 of the WTO/TBT agreement. This SANS edition is technically identical to SABS EN 81-2:1998, with

21、the addition of EN corrigendum, EN amendments A2 and A1, and national amendment 1. Users of SANS 50081-2 should note that an SANS standard (SANS 1545-2) exists, which is based on SANS 50081-2, but which has additional information regarding the application of SANS 50081-2 in the South African environ

22、ment. SANS 1545-2 is a front-end standard. Deviations from the international requirements in this standard are given in SANS 1545-2. In the case of dispute, SANS 1545-2 will take precedence over this standard. This page is intentionally left blankEUROPEAN STANDARDNORME EUROPENNEEUROPISCHE NORMEN 81-

This Amendment to the European Standard EN 81-2:1998 shall be given t

31、he status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the latest by May 2006. This European Standard has been prepared under a mandate given to CEN by the European Commission

32、 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 European Standard. The 1998 edition of EN 81-2, under 14.1.2.1.1 b) 3) and Annex H foresees the use of

33、electronic components in safety circuits thus giving hardware provisions. This amendment extends their use to permit the inclusion of software (programmable electronic systems - PESSRAL). This amendment A1 covers those aspects that need to be addressed when programmable electronic systems (PESSRAL)

34、are used to carry out electric safety functions for lifts within the scope of EN 81-2:1998 and EN 81-2:1998/A2:2004. This amendment A1 covers the necessary additional precautions by replacing the relevant existing text of EN 81-2:1998 or adding new clauses as indicated. NOTE Drafting and presentatio

35、n of the amended text has been arranged to comply with the presentation of EN 81-2:1998. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark

36、, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
