24、OGY RULES FOR THE DESIGNATION OF MEASURING INSTRUMENTS 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-opera
25、tion 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
26、“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, governmental and non- governmental organizations liaising with the IEC also participate in this prep
27、aration. 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 cons
28、ensus 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
29、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 order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
30、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 clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cann
31、ot 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 shall attach to IEC or its directors, employees, servants or agents including individual experts and me
32、mbers 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
33、 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 publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication
34、 may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62419 has been prepared by IEC technical committee 65: Industrial-process measurement, control and automation. This standard cancels and replaces IEC/PAS
35、62419 published in 2005. This first edition constitutes a technical revision. This bilingual version (2014-04) corresponds to the monolingual English version, published in 2008-11. The text of this standard is based on the following documents: FDIS Report on voting 65/429/FDIS 65/430/RVD Full inform
36、ation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. 4 IEC 62419:2008 IEC 2008 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The com
37、mittee 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, replaced by a re
38、vised edition, or amended. IEC 62419:2008 IEC 2008 5 INTRODUCTION The state of science concerning quantities and units has undergone significant changes in the last century. During the period from 1920 to 1960 there was a fundamental change in the comprehension and usage of physical quantities, whic
39、h was particularly promoted by the works of Julius Wallot published between 1922 and 1953. In this process the various systems of physical units and the usage of numerical equations were replaced by the SI-units (see ISO 1000) and the usage of quantity equations. So the quantities were no longer lin
40、ked to certain units. This development culminated in the publishing of the first edition of the German standard DIN 1313 Notation of physical equations in sciences and technology in 1931 and the resolutions of the tenth general conference of weights and measures in 1954. Since then it has been consi
41、dered incorrect to address a quantity by its unit. In view of this, measuring instruments should not be addressed by the unit of the measured quantity but only by the measured quantity or the measuring task itself. Referring to the question of market relevance, it must be stated, that especially wit
42、h respect to the international project of standardized classification and documentation in multilingual equipment descriptions, it is important to critically address the situation regarding the designation of measuring instruments. Ideally, every manufacturer should use the same terminology. In prac
43、tice, there is confusion in the proper designation of measuring instruments within catalogues and sales brochures which also has consequences in technical literature. It is not the intention of this standard to enforce particular usages in any language but to make recommendations that remove the lin
44、guistic confusion in this field or at least, reduce it. Considering the urgent necessity of unambiguous technical communication over language boundaries, this is a legitimate goal. This could also be considered to be a matter of global importance. 6 IEC 62419:2008 IEC 2008 CONTROL TECHNOLOGY RULES F
45、OR THE DESIGNATION OF MEASURING INSTRUMENTS 1 Scope and object This International Standard is applicable to measurement technology. It defines rules for the unambiguous designation of different types of measuring instruments and of measuring instrument features with the intention of enabling unambig
46、uous technical communication over language boundaries. The scope of this International Standard is the adaptation of the designation of measuring instruments and of measuring instrument features to the state of science by designating them according to the measuring quantity or the measuring task ins
47、tead of the unit, and the adaptation of the designation of measuring instruments and of measuring instrument features to the terms given in the ISO/IEC Guide 99 (VIM). It is strongly recommended that “ measuring instrument” is used as secondary component in compound terms. This is consistent with th
48、e objective of standardization, namely uniformity, especially since the meaning of other secondary components, e.g. “indicator”, “gauge”, “meter”, is no more descriptive than that of the standard component in this context. For exceptions see 4.1 and A.2. The ambiguous secondary component “. sensor”
49、shall not be used. In its place one of the secondary components “ sensing element”, “. detector”, “. transformer”, “. transducer”, “ transmitter”, “. measuring instrument” or “. measuring chain” shall be used, depending on the task of the functional unit being termed. The definitions for detector (detecting device), transformer, transducer and transmitter are given in IEC 60050-351. 2 Normative references The following reference
