17、irements for the basic safety and essential performance of X-ray tube assemblies for medical diagnosis FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The ob

18、ject 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, Publicly Available Specificat

19、ions (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- governmental organizations lia

20、ising 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 technical matters expre

21、ss, 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 by IEC National Committ

22、ees 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 uniformity, IEC National

23、 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. 5) IEC itself does not

24、 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 ensure that they have th

25、e 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 of any nature whatsoever

26、, 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 referenced publications

27、 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. DISCLAIMER This Redline

28、version is not an official IEC Standard and is intended only to provide the user with an indication of what changes have been made to the previous version. Only the current version of the standard is to be considered the official document. This Redline version provides you with a quick and easy way

29、to compare all the changes between this standard and its previous edition. A vertical bar appears in the margin wherever a change has been made. Additions are in green text, deletions are in strikethrough red text. 4 IEC 60601-2-28:2017 RLV IEC 2017 International Standard IEC 60601-2-28 has been pre

30、pared by subcommittee 62B: Diagnostic imaging equipment, of IEC technical committee 62: Electrical equipment in medical practice. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. The third edition of this particular standard

31、 has been prepared to fit IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 (the amended third edition of IEC 60601-1), which is referred to as the general standard. Apart from the changes related to the amendment of IEC 60601-1, changes related to technical improvements are also included. The text of

32、 this standard is based on the following documents: FDIS Report on voting 62B/1040/FDIS 62B/1051/RVD Full information on the voting for the approval of this particular standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the

33、 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 references: in smaller type. Normative text of tables is also i

34、n 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 within the table of contents, inclusive of all subdivisions (e

35、.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” followed by the clause number. References to subclauses within

36、 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 verbal forms used in this standard conform to usage described in Clause 7 of the ISO/IEC Directives, Part 2. For

37、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 is not mandatory for compliance with this standard; “may” is us

38、ed 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. IEC 60601-2-28:2017 RLV IEC 2017 5 The committee has decided that the conte

39、nts 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 publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The “

Users should therefore print this publication using a colour printer. 6 IEC 60601-2-28:2017 RLV IEC 2017 MEDICAL ELECTRICAL EQ

41、UIPMENT Part 2-28: Particular requirements for the basic safety and essential performance of X-ray tube assemblies for medical diagnosis 201.1 Scope, object and related standards Clause 1 of the general standard 1applies, except as follows: 201.1.1 Scope Replacement: This part of IEC 60601 applies t

42、o the BASIC SAFETY and ESSENTIAL PERFORMANCE of X-RAY TUBE ASSEMBLIES and to components thereof, hereafter referred to as ME EQUIPMENT, intended for medical diagnosis and imaging. Where the general standard IEC 60601-1 and the collateral standard IEC 60601-1-3 refer to ME EQUIPMENT, this is interpre

43、ted as X-RAY TUBE ASSEMBLIES in this particular standard. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME

44、 EQUIPMENT and to ME SYSTEMS, as relevant. NOTE This document is also applicable to the X-RAY TUBE ASSEMBLY aspects of X-RAY SOURCE ASSEMBLIES and X- RAY TUBE HEADS. 201.1.2 Object Replacement: The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL PERFORMANCE r

45、equirements for X-RAY TUBE ASSEMBLIES for medical diagnosis. 201.1.3 Collateral standards Addition: This particular standard refers to those applicable collateral standards that are listed in Clause 2 of the general standard and Clause 201.2 of this particular standard. IEC 60601-1-3:2008 and IEC 60

46、601-1-3:2008/AMD1:2013 apply as modified in Clause 203. IEC 60601-1-2, IEC 60601-1-6, IEC 60601-1-8, IEC 60601-1-9, IEC 60601-1-10, IEC 60601-1- 11 and IEC 60601-1-12 do not apply. All other published collateral standards in the IEC 60601-1 series apply as published. NOTE 101 IEC 60601-1-2 does not

47、apply because RISKS for the X-RAY TUBE ASSEMBLY outside the system may only be indicative of RISKS for the system due to the difference in electromagnetic environment. NOTE 102 IEC 60601-1-6 and IEC 60601-1-8 do not apply because X-RAY TUBE ASSEMBLIES are not operated as a stand-alone device. _ 1The

48、 general standard is IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012, Medical electrical equipment Part 1: General requirements for basic safety and essential performance. IEC 60601-2-28:2017 RLV IEC 2017 7 NOTE 103 X-RAY TUBE ASSEMBLIES are not in the scope of IEC 60601-1-10, IEC 60601-1-11 and IEC

49、 60601-1-12. 201.1.4 Particular standards Replacement: In the IEC 60601 series, particular standards may modify, replace or delete requirements contained in the general standard and collateral standards as appropriate for the particular ME EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL PERFORMANCE requirements. A requirement of a particular standard takes priority over the general standard. For brevity, IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 are re
