22、idance and interpretation Electromagnetic immunity: performance of medical electrical equipment and medical electrical systems FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nati
23、onal 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 Specifications, Technical Reports, Publi
24、cly 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, governmental and non-governm
25、ental 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 decisions or agreements of IEC on
26、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 international use and are accepted
27、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 order to promote international u
28、niformity, 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 clearly indicated in the latter.
29、 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 carried out by independent certification bodies. 6) All users should e
30、nsure 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 Committees for any personal injury, property damage or other damage o
31、f 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 drawn to the Normative references cited in this publication. Use of the
32、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 be held responsible for identifying any or all such patent rights. T
33、he main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of th
34、e art“. IEC 60601-4-2, which is a technical report, has been prepared by IEC subcommittee 62A: Common aspects of electrical equipment used in medical practice, of IEC technical committee 62: Electrical equipment in medical practice. PD IEC/TR 60601-4-2:2016 6 IEC TR 60601-4-2:2016 IEC 2016 The text
35、of this technical report is based on the following documents: Enquiry draft Report on voting 62A/1068/DTR 62A/1073A/RVCFull information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafted in acco
36、rdance with the ISO/IEC Directives, Part 2. In this technical report, the following print types are used: Recommendations and definitions: roman type. Test instructions: italic type. Informative material appearing outside of tables, such as notes, examples and references: in smaller type. Normative
37、text of tables is also in a smaller type. TERMS DEFINED IN CLAUSE 3 OF THIS TECHNICAL REPORT OR AS NOTED: SMALL CAPITALS. In referring to the structure of this technical report, the term “clause” means one of the numbered divisions within the table of contents, inclusive of all subdivisions (e.g. Cl
38、ause 1 includes 1.1, 1.2, etc.); “subclause” means a numbered subdivision of a clause (e.g. 1.1, 1.2 and 1.3.1 are all subclauses of Clause 1). References to clauses within this technical report are preceded by the term “Clause” followed by the clause number. References to subclauses within this tec
39、hnical report are by number only. In this technical report, the conjunctive “or” is used as an “inclusive or” so a statement is true if any combination of the conditions is true. The verbal forms used in this technical report conform to usage described in Annex H of the ISO/IEC Directives, Part 2. F
40、or the purposes of this technical report, the auxiliary verb: “shall” means that compliance with a requirement or a test is mandatory for compliance with this technical report; however, we chose to use it in this technical report only as described in 0.3; “should” means that compliance with a requir
41、ement or a test is recommended but is not mandatory for compliance with this technical report; “may” is used to describe a permissible way to achieve compliance with a requirement or test. An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title indicates t
42、hat there is guidance or rationale related to that item in Annex A. A list of all parts of the IEC 60601 series, published under the general title Medical electrical equipment, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged unti

PD IEC/TR 60601-4-2:2016 8 IEC TR 60601-4-2:2016 IEC 2016 INTRODUCTION 0.1 * General MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS are used in the practice of medicine because they provide needed functions that are associated with the INTENDED USE. I
46、f MEDICAL ELECTRICAL EQUIPMENT or a MEDICAL ELECTRICAL SYSTEM does not provide these needed functions because of a lack of IMMUNITY to ELECTROMAGNETIC DISTURBANCES that are expected to occur in the environment(s) of INTENDED USE, this can interfere with the practice of medicine. This document provid
47、es guidance on assessing IMMUNITY, with regard to the INTENDED USE. Based on the INTENDED USE, MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS should have adequate IMMUNITY to provide the performance specified by the MANUFACTURER in the presence of ELECTROMAGNETIC DISTURBANCES. See Annex
48、 A for more information regarding performance. Guidance for IMMUNITY with regard to INTENDED USE can be useful for MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS for which the BASIC SAFETY AND ESSENTIAL PERFORMANCE do not include the purpose(s) for which the ME EQUIPMENT or ME SYSTEM wa
49、s purchased. It is important to the OPERATOR or RESPONSIBLE ORGANIZATION and to the delivery of healthcare that these functions operate as intended in the EM ENVIRONMENTS of INTENDED USE. Examples of performance that might not be BASIC SAFETY or ESSENTIAL PERFORMANCE but that might be INTENDED USE include the following: the ability to print an ultrasound image remotely; the ability of a scale to accurately measure PATIENT weight; accuracy of X-RAY TUBE V
