10、AL ELECTROTECHNICAL COMMISSION _ MEDICAL ELECTRICAL EQUIPMENT GLOSSARY OF DEFINED TERMS 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
11、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 Specifications, Technical Reports, Publicly Available Specifications (PAS) and
12、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, governmental and non- governmental organizations liaising with the
13、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 decisions or agreements of IEC on technical matters express, as nearly a
14、s 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 international use and are accepted by IEC National Committees in that sen
15、se. 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 order to promote international uniformity, IEC National Committees und
16、ertake 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 clearly indicated in the latter. 5) IEC provides no marking procedure
17、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 shall attach to IEC or its directors, employees, servants or agents in
18、cluding 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 legal fees) and expenses arising out of the publication, use of, or re
19、liance 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 publication. 9) Attention is drawn to the possibility that some of the
20、 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. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a tec
21、hnical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 60788, which is a technical report, has been prepared by IEC TC 62: Electrical EQUIPMENT in medical practice. This second edition cance
22、ls and replaces the first edition of IEC 60788 published in 1984. This second edition constitutes a technical revision. The text of this technical report is based on the following documents: Enquiry draft Report on voting 62/137/DTR 62/140/RVC Full information on the voting for the approval of this
23、technical report can be found in the report on voting indicated in the above table. This publication does not follow the rules for structuring International Standards as given in Part 2 of the ISO/IEC Directives.TR 60788 IEC:2004(E) 3 The committee has decided that the contents of this publication w
24、ill remain unchanged until 2005. At this date, the publication will be reconfirmed; w i t h d r a w n ; replaced by a revised edition, or amended. 4 TR 60788 IEC:2004(E) INTRODUCTION Purpose To provide an actual mirror of defined terms for all steps in the development of IEC standards under the scop
25、e of “MEDICAL ELECTRICAL EQUIPMENT”, IEC TC 62. To give guidance for harmonisation of the defined terms used in the IEC standards on “MEDICAL ELECTRICAL EQUIPMENT”. Contents All DEFINED TERMS used in the General, Particular and Collateral Standards, recorded in the project files of the IEC for TC 62
26、, SC 62A, 62B, 62C and 62D are mirrored. Recommendations to avoid existing redundancy are added as red text in the column “Definitions” in the table. Maintenance An annual maintenance cycle for this TR is introduced. Closing date for the editorial input is the middle of December of a year. The annua
27、l editorial maintenance is done by the Secretaries of the IEC technical committee 62 and its subcommittees 62A, 62B, 62C and 62D. The compilation (addition of new terms and deletion of obsolete terms) is done by the Secretary of IEC TC 62. Targets Represent the state-of-the-art in the definitions Ha
28、rmonize the language of the IEC publications Ease translations of the IEC publications Enable self-control by the experts working in projects for MEDICAL ELECTRICAL EQUIPMENT. Coded reference of the DEFINED TERMS In all cases as appropriate the reference codes “IEV xxx-xx-xx” of the International El
29、ectronic Vocabulary (IEV) are added in the “Reference” column of the table. F o r DEFINED TERMS used in RADIOLOGY the reference codes “rm-xx-xx” remain unchanged as initiated by IEC 60788 Ed.1. For main fields other than RADIOLOGY, the coded references will be generated in future annual editions. Re

31、 MEDICAL ELECTRICAL EQUIPMENT, and are on the list of publications as stated in May 2003. 2 Normative references The documents referenced in 2.2 are forming the sources for the defined terms in this document. 2.1 General The defined terms listed in this glossary are mirrored as presented in the stan
32、dards and technical reports. Only the recommendations are added for further harmonisation of multiple defined terms. The glossary is prepared to ease the use of the electronic version by two search functions: Search in the alphabetic order, and Search by the technical and physical chapters in case o
