34、IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addit
35、ion to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interest
36、ed in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with
37、conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC
38、 National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for t
39、he way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between an
40、y IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformi
41、ty. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members
42、of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or an
43、y other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may b
44、e the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62566 has been prepared by subcommittee 45A: Instrumentation and control of nuclear facilities, of IEC technical committee 45: Nuclear instrumentation. The text
45、 of this Standard is based on the following documents: FDIS Report on voting 45A/859/FDIS 45A/865/RVD Full information on the voting for the approval of this Standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC D
46、irectives, Part 2. 6 62566 IEC:2012 The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconf
47、irmed, withdrawn, replaced by a revised edition, or amended. 62566 IEC:2012 7 INTRODUCTION a) Technical background, main issues and organisation of the Standard The electronic systems of class 1 (according to IEC 61513) used in Nuclear Power Plants (NPP) which are required in emergency situations, n
48、eed to be fully validated and qualified before being used in operation. In traditional systems that are computer-based, a separation can be drawn between the hardware and software portions. The hardware is mainly designed with standardised components having pre-defined electronic functions such as m
49、icroprocessors, timers or network controllers, whereas software is used to coordinate the different parts of the hardware and to implement the application functions. Nowadays, I 2) an approach to analyse and select the blank integrated circuits, micro-electronic technologies and Pre-Developed Blocks (PDB, 3.11) used to develop HPDs; 3) procedures for the modification and configuration control of HPDs; 4) requirements fo
