31、 2016 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ INDUSTRIAL-PROCESS MEASUREMENT, CONTROL AND AUTOMATION EVALUATION OF SYSTEM PROPERTIES FOR THE PURPOSE OF SYSTEM ASSESSMENT Part 2: Assessment methodology FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for
32、 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 addition to other activities, IEC publish
33、es 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 interested in the subject dealt with may par
34、ticipate 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 conditions determined by agreement b
35、etween 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 National Committees. 3) IEC Publica
36、tions 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 the way in which they are used or for
37、 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 any IEC Publication and the correspond
38、ing 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 conformity. IEC is not responsible for any s
39、ervices 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 of its technical committees and IEC
40、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 any other IEC Publications. 8) Attenti
41、on 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 be the subject of patent rights. IEC
42、shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61069-2 has been prepared by subcommittee 65A: System aspects, of IEC technical committee 65: Industrial-process measurement, control and automation. This second edition cancels and replaces the f
43、irst edition published in 1993. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Reorganization of the material of IEC 61069-2:1993 to make the overall set of standards more organized and consist
44、ent; b) IEC TS 62603-1:2014 has been incorporated into this edition. BS EN 61069-2:2016IEC 61069-2:2016 IEC 2016 5 The text of this standard is based on the following documents: FDIS Report on voting 65A/790/FDIS 65A/799/RVD Full information on the voting for the approval of this standard can be fou
45、nd in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61069 series, published under the general title Industrial-process measurement,control and automation Evaluation of system prop
46、erties for the purpose of system assessment, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At
47、this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users shoul

BS EN 61069-2:2016 6 IEC 61069-2:2016 IEC 2016 INTRODUCTION IEC 61069 deals with the method which should be used to assess system properties of a basic control system (BCS). IEC 61069 consists of the following parts: Part 1: Terminology and bas
49、ic concepts Part 2: Assessment methodology Part 3: Assessment of system functionality Part 4: Assessment of system performance Part 5: Assessment of system dependability Part 6: Assessment of system operability Part 7: Assessment of system safety Part 8: Assessment of other system properties Assessment of a system is the judgement, based on evidence, of the suitability of the system for a specific mission or class of missions. To obtain total evidence would require c
