28、nce of electron accelerators in the range 1 MeV to 50 MeV 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-op
29、eration 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
30、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 IEC also participate in this pr
31、eparation. 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 co
32、nsensus 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 effort
33、s 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 Publication
34、s 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 itself does not provide any attestation of conformity. Indepe
35、ndent 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 ensure that they have the latest edition of this publication. 7) No li
36、ability 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 (in
37、cluding 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
38、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. International Standard IEC 60601-2-1 has been prepared by IEC subcommi
39、ttee 62C: Equipment for radiotherapy, nuclear medicine and radiation dosimetry, of IEC technical committee 62: Electrical equipment in medical practice. This third edition cancels and replaces the second edition published in 1998 and its Amendment 1 (2002). It constitutes a technical revision. 60601
40、-2-1 IEC:2009 5 This third edition addresses the following issues not covered in previous editions: alignment with the new relevant collateral standards; new technologies in radiotherapy, including: stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT); intensity modulated radiotherapy
41、 (IMRT); electronic imaging devices (e.g. EPID); moving beam radiotherapy (dynamic therapy). The text of this particular standard is based on the following documents: FDIS Report on voting 62C/474/FDIS 62C/480/RVD Full information on the voting for the approval of this particular standard can be fou
42、nd in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. In this standard, the following print types are used: Requirements and definitions: roman type. Test specifications: italic type. Informative material appeari
43、ng outside of tables, such as notes, examples and references: in smaller type. Normative text of tables is also in a smaller type. TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS PARTICULAR STANDARD OR AS NOTED: SMALL CAPITALS. In referring to the structure of this standard, the term “cla
44、use” means one of the seventeen numbered divisions within the table of contents, inclusive of all subdivisions (e.g. Clause 7 includes subclauses 7.1, 7.2, etc.); “subclause” means a numbered subdivision of a clause (e.g. 7.1, 7.2 and 7.2.1 are all subclauses of Clause 7). References to clauses with
45、in this standard are preceded by the term “Clause” followed by the clause number. References to subclauses within this particular standard are by number only. In this standard, the conjunctive “or” is used as an “inclusive or” so a statement is true if any combination of the conditions is true. The
46、verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC Directives, Part 2. For the purposes of this standard, the auxiliary verb: “shall” means that compliance with a requirement or a test is mandatory for compliance with this standard; “should” means that compliance
47、 with a requirement or a test is recommended but is not mandatory for compliance with this standard; “may” is used to describe a permissible way to achieve compliance with a requirement or test. A list of all parts of the IEC 60601 series, published under the general title: Medical electrical equipm
48、ent can be found on the IEC website. 6 60601-2-1 IEC:2009 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,
49、 the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60601-2-1 IEC:2009 7 INTRODUCTION The use of ELECTRON ACCELERATORS for RADIOTHERAPY purposes may expose PATIENTS to danger if the ME EQUIPMENT fails to deliver the required dose to the PATIENT, or if the ME EQUIPMENT design does not satisfy standards of electrical
