31、nical 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-operation on all questions concerning standardization in the electrical and electronic fields. To thi

32、s 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 “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National

33、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 preparation. IEC collaborates closely with the International Organization for Standardization (ISO) i

34、n 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 consensus of opinion on the relevant subjects since each technical committee has representation from

35、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 are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held

36、 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 transparently to the maximum extent possible in their national and regional publications. Any div

37、ergence 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. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC

38、 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 liability shall attach to IEC or its directors, employees, servants or agents including individual ex

39、perts 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 reliance upon, this IEC

40、 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 elements of this IEC

41、 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 60601-2-11 has been prepared by subcommittee 62C: Equipment for radiotherapy, nuclear medicine and radiation dosimetry, of IEC technical commi

42、ttee 62: Electrical equipment in medical practice. This third edition cancels and replaces the second edition of IEC 60601-2-11 published in 1997 and its Amendment 1:2004. This edition constitutes a technical revision which brings this standard in line with the third edition of IEC 60601-1 and its c

43、ollateral standards. The text of this standard is based on the following documents: FDIS Report on voting 62C/552/FDIS 62C/558/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

44、C:2013 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 appearing outside of tables, such as notes, examples and

45、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 “clause” means one of the seventeen numbered divisions

46、 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 within this standard are preceded by the term “Clause”

47、 followed by the clause number. References to subclauses within this collateral 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 verbal forms used in this standard conform to usag

48、e 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 with a requirement or a test is recommended but i

49、s 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 equipment, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific pu
