23、s been prepared by Technical Committee CEN/TC 10 “Lifts, escalators and moving walks”, the secretariat of which is held by AFNOR. This Amendment to the European Standard EN 81-1:1998 shall be given the status of a national standard, either by publication of an identical text or by endorsement, at th
24、e latest by May 2006, and conflicting national standards shall be withdrawn at the latest by May 2006.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 and the European Free Trade Association, and supports essential requirements of EU Directive(s). For
25、 relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. The 1998 edition of EN 81-1, under 14.1.2.1.1 b) 3) and Annex H foresees the use of electronic components in safety circuits thus giving hardware provisions. This amendment extends thei
26、r 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) are used to carry out electric safety functions for lifts within the scope of EN 81-1:1998 and EN 81-
27、1:1998/A2:2004. This amendment A1 covers the necessary additional precautions by replacing the relevant existing text of EN 81-1:1998 or adding new clauses as indicated. NOTE Drafting and presentation of the amended text has been arranged to comply with the presentation of EN 81-1:1998. According to
28、 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, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Lux

This led to a necessary classification of safety functions applied to PESSRAL.” 0.3.5 shall be amended as follows: “0.3.5 The requirements of this European Standard regarding electrical safety devices are such that the possibility of a
31、failure of an electric safety device (see 14.1.2.1.1 b) complying with all the requirements of this European Standard need not to be taken into consideration.” 2 Modifications in Clause 2 Clause 2 shall be amended as follows: “EN 61508-1:2001, Functional safety of electrical/electronic/programmable
