33、CTROTECHNICAL COMMISSION _ INDUSTRIAL-PROCESS MEASUREMENT, CONTROL AND AUTOMATION EVALUATION OF SYSTEM PROPERTIES FOR THE PURPOSE OF SYSTEM ASSESSMENT Part 5: Assessment of system dependability FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardiz
34、ation 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 publishes Internat
35、ional 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 participate in
36、 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 between the
37、 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 Publications have
38、 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 any misin
39、terpretation 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 corresponding nation
40、al 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 services ca
41、rried 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 National C
42、ommittees 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) Attention is draw
43、n 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 shall not
44、be held responsible for identifying any or all such patent rights. International Standard IEC 61069-5 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 first editi
45、on published in 1994. 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 61069-5:1994 to make the overall set of standards more organized and consistent; b) IE
46、C TS 62603-1 has been incorporated into this edition. IEC 61069-5:2016 IEC 2016 5 The text of this standard is based on the following documents: FDIS Report on voting 65A/793/FDIS 65A/803/RVD Full information on the voting for the approval of this standard can be found in the report on voting indica
47、ted 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 properties for the purpose of system
48、 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 web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will
49、 be reconfirmed, withdrawn, replaced by a revised edition, or amended.
