25、CTROTECHNICAL COMMISSION _ PROCESS MEASUREMENT AND CONTROL DEVICES GENERAL METHODS AND PROCEDURES FOR EVALUATING PERFORMANCE Part 1: General considerations FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrot

26、echnical 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 International Standards, Technical Specificati

27、ons, 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 this preparatory work. International,

28、 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 two organizations. 2) The formal decis

29、ions 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 the form of recommendations for intern

30、ational 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 misinterpretation by any end user. 4) In ord

31、er 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 national or regional publication shall be cle

32、arly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability sha

33、ll 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 leg

34、al 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 pub

35、lication. 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 61298-1 has been prepared by subcommittee 65B: Devices

36、 and process analysis, of IEC technical committee 65: Industrial-process measurement, control and automation. This second edition cancels and replaces the first edition published in 1995 and constitutes a technical revision. This edition is a general revision with respect to the previous edition and

37、 does not include any significant changes (see Introduction). 61298-1 IEC:2008 5 The text of this standard is based on the following documents: FDIS Report on voting 65B/685/FDIS 65B/693/RVDFull information on the voting for the approval of this standard can be found in the report on voting indicate

38、d in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61298 series, under the general title Process measurement and control devices General methods and procedures for evaluating performance, can be found on the IEC w

39、ebsite. The committee has decided that the contents of this publication will remain unchanged until the maintenance result 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, r

40、eplaced by a revised edition, or amended. 6 61298-1 IEC:2008 INTRODUCTION This standard is not intended as a substitute for existing standards, but is rather intended as a reference document for any future standards developed within the IEC or other standards organizations, concerning the evaluation

41、 of process instrumentation. Any revision of existing standards should take this standard into account. This common standardized basis should be utilized for the preparation of future relevant standards, as follows: any test method or procedure, already treated in this standard, should be specified

42、and described in the new standard by referring to the corresponding clause of this standard. Consequently new editions of this standard are revised without any change in numbering and scope of each clause; any particular method or procedure, not covered by this standard, should be developed and spec

43、ified in the new standard in accordance with the criteria, as far as they are applicable, stated in this standard; any conceptual or significant deviation from the content of this standard, should clearly be identified and justified if introduced in a new standard. 61298-1 IEC:2008 7 PROCESS MEASURE

44、MENT AND CONTROL DEVICES GENERAL METHODS AND PROCEDURES FOR EVALUATING PERFORMANCE Part 1: General considerations 1 Scope This part of IEC 61298 specifies general methods and procedures for conducting tests, and reporting on the functional and performance characteristics of process measurement and c

45、ontrol devices. The methods and procedures specified in this standard are applicable to any type of process measurement and control device. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function

46、) between the inputs and outputs, and include analogue and digital devices. For devices that require special tests, this standard should be used, together with any product specific standard specifying special tests. This standard covers general principles which apply to the series. 2 Normative refer
