Due to the medical content of this Standard, it was also approved by the Te

11、chnical Committee on Applications of Electricity in Health Care under the jurisdiction of the Strategic Steering Committee on Health Care Technology. Lists of the members of these Technical Committees are available upon request. This Standard has been approved as a National Standard of Canada by the

12、 Standards Council of Canada. Interpretations: The Strategic Resource Group has provided the following direction for the interpretations of standards under its jurisdiction: “The literal text shall be used in judging compliance of products with the safety requirements of this Standard. When the lite

13、ral text cannot be applied to the product, such as for new materials or construction, and when a relevant committee interpretation has not already been published, CSAs procedures for Interpretation shall be followed to determine the intended safety principle.” June 200 7 0 Canadian Standards Associa

16、1-2-7-07 Medical electrical equipment - Part 2-7: Particular requirements for the safety of high-voltage generators of diagnostic X-ray generators CSA Foreword The Canadian Standards Association (CSA) develops standards under the name Canadian Standards Association, and provides certification and te

17、sting under the name CSA International. CSA International provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number

18、 of products is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasi

19、ble, programs will be developed for additional products for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other par

20、ty. The opinions and findings of the Association represent its professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a min

21、or difference or a new feature may be deemed to meet the Standard providing the feature or difference is found acceptable utilizing appropriate CSA International Operating Procedures. Products that comply with this Standard shall not be certified if they are found to have additional features which a

22、re inconsistent with the intent of this Standard. Products shall not be certifiable if they are discovered to contravene applicable laws or regulations. Testing techniques, test procedures, and instrumentation frequently must be prescribed by CSA International in addition to the technical requiremen

23、ts contained in Standards of CSA. In addition to markings specified in the Standard, CSA International may require special cautions, markings, and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes no

24、r accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility, or personnel for or in connection with the test is furn

25、ished by the manufacturer or the Association. Manufacturers should note that, in the event of the failure of CSA International to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should submit the matter, in writing, to the Secretary of

26、the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please remember, when making application for certification, to request all current Amendments, Bulletins, Notices, and Technical Information Letters that may be applicable and for which there may be a n

27、ominal charge.

38、IPMENT - Part 2-7: Particular requirements for the safety of high-voltage generators of diagnostic X-ray generators FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Commit

39、tees). The object of the 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, the IEC publishes International Standards. Their preparation is entrusted to technical committee

40、s; 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 preparation. The IEC collaborates closely with the International Organization for

41、 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of oprmon on the relevant subjects since each technical committ

42、ee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promo

43、te international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly ind

44、icated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may b

45、e the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60601-2-7 has been prepared by subcommittee 628: Diagnostic imaging equipment, of IEC technical committee 62: Electrical equipment in medical practice. This

46、 second edition cancels and replaces the first edition published in 1987, and constitutes a technical revision. The text of this standard is based on the following documents: I FDIS I Report on voting I I 62B1329IFDIS I 6281334lRVD I Full information on the voting for the approval of this standard c
