3、er 2012 by American National Standards Institute, Inc. Abstract: The second edition of this technical report was prepared by the Secretariat of IEC/SC 62A to summarize those changes cited in Amendment 1 that were assessed during the development process as having a moderate to significant impact on u
4、sers of IEC 60601-1. The tables from the first edition of this technical report were retained in the second edition because there are counties that have not fully transitioned to the third edition of IEC 60601-1. Therefore, the original contents of IEC/TR 62348 remain useful in those countries. Keyw

Printed in the United States of America ISBN 1570204756 AAMI Technical Information Report A technical information report (TIR) is a publication of the Association for the Advancement of Medical Instrumentation (AAMI) Standards Board that addresses a particular aspect of m
10、edical technology. Although the material presented in a TIR may need further evaluation by experts, releasing the information is valuable because the industry and the professions have an immediate need for it. A TIR differs markedly from a standard or recommended practice, and readers should underst
11、and the differences between these documents. Standards and recommended practices are subject to a formal process of committee approval, public review, and resolution of all comments. This process of consensus is supervised by the AAMI Standards Board and, in the case of American National Standards,
12、by the American National Standards Institute. A TIR is not subject to the same formal approval process as a standard. However, a TIR is approved for distribution by a technical committee and the AAMI Standards Board. Another difference is that, although both standards and TIRs are periodically revie
13、wed, a standard must be acted onreaffirmed, revised, or withdrawnand the action formally approved usually every five years but at least every 10 years. For a TIR, AAMI consults with a technical committee about five years after the publication date (and periodically thereafter) for guidance on whethe
14、r the document is still usefulthat is, to check that the information is relevant or of historical value. If the information is not useful, the TIR is removed from circulation. A TIR may be developed because it is more responsive to underlying safety or performance issues than a standard or recommend
15、ed practice, or because achieving consensus is extremely difficult or unlikely. Unlike a standard, a TIR permits the inclusion of differing viewpoints on technical issues. CAUTION NOTICE: This AAMI TIR may be revised or withdrawn at any time. Because it addresses a rapidly evolving field or technolo
16、gy, readers are cautioned to ensure that they have also considered information that may be more recent than this document. All standards, recommended practices, technical information reports, and other types of technical documents developed by AAMI are voluntary, and their application is solely with
17、in the discretion and professional judgment of the user of the document. Occasionally, voluntary technical documents are adopted by government regulatory agencies or procurement authorities, in which case the adopting agency is responsible for enforcement of its rules and regulations.
