31、EMS Part 1: Methods of evaluating the performance FOREWORD 1) The International Electrotechnical Commission (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
32、on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
33、Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested 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 preparati
34、on. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with 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
35、 of opinion on the relevant subjects since each technical committee has representation from all interested IEC 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 m
36、ade 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 misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications trans
37、parently to the maximum extent possible in their national and regional publications. Any divergence between any 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 c
38、ertification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. 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
39、 shall attach to IEC or its directors, employees, servants or agents including individual experts and members 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
40、 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 drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this
41、 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 be held responsible for identifying any or all such patent rights. International Standard IEC 60546-1 has been prepared by subcommittee 65B: Dev
42、ices and process analysis, of IEC technical committee 65: Industrial-process measurement, control and automation. This third edition cancels and replaces the second edition, published in 1987. This third edition constitutes a minor technical revision made to bring terms, measurement units and refere
43、nces up to date. The text of this standard is based on the following documents: CDV Report on voting 65B/659A/CDV 65B/717A/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 6 60546-1 IEC:2010 This publication has b
44、een drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 60546 series, under the general title: Controllers with analogue signals for use in industrial-process control systems, can be found on the IEC website. The committee has decided that the contents of this p
45、ublication 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 reconfirmed, withdrawn, replaced by a revised edition, or amended. 60546-1 IEC:2010 7 INTRODUCT
46、ION The methods of evaluation given in this International Standard are intended for use by manufacturers to determine the performance of their products and by users, or independent testing establishments, to verify manufacturers performance specifications. Part 2 of IEC 60546 describes a limited ser
47、ies of tests which may be used as acceptance tests. The tests specified in this standard are not necessarily sufficient for instruments specifically designed for unusually arduous duties. Conversely, a restricted series of tests may be suitable for instruments designed to perform within a limited ra
48、nge of conditions. It will be appreciated that the closest liaison should be maintained between an evaluating body and the manufacturer. Note is taken of the manufacturers specifications for the instrument when the test program is being decided, and the manufacturer should be invited to comment on b
49、oth the test program and the results. His comments on the results should be included in any report produced by the testing organization. 8 60546-1 IEC:2010 CONTROLLERS WITH ANALOGUE SIGNALS FOR USE IN INDUSTRIAL-PROCESS CONTROL SYSTEMS Part 1: Methods of evaluating the performance 1 Scope This International Standard applies to proportional-integral-derivative (PID) pneumatic an
