12、 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 this end and in addition to other activi

13、ties, 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 Committee interested in the subject d

14、ealt 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) in accordance with conditions determi

15、ned 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 all interested IEC National Committe

16、es. 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 responsible for the way in which th

17、ey 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 divergence between any IEC Publication

18、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 marks of conformity. IEC is not res

19、ponsible 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 experts and members of its technical c

20、ommittees 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 Publication or any other IEC Public

21、ations. 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 Publication may be the subject of p

22、atent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different k

23、ind from that which is normally published as an International Standard, for example “state of the art“.

29、logy. Establishing the safety and effectiveness of a medical device containing software requires well designed software that fulfils its purpose without causing any unacceptable risks. Following an internationally approved set of software development practices provides one way of achieving this. Thi

30、s technical report (TR) provides a framework of life cycle processes supporting the safe design and maintenance of medical device software called the process reference model (PRM). The process descriptions in this PRM are fully compliant with the requirements of ISO/IEC 24774:2010, Systems and softw

31、are engineering Life cycle management Guidelines for process description. This TR presents the PRM for medical device software development as a result of integrating requirements from IEC 62304:2006 and from the international standard of software life-cycle processes ISO/IEC 12207:2008. This TR is a

32、imed at medical device software developers who can use it for realizing the set of requirements they have to achieve to be compliant with IEC 62304:2006 in the scope of the safety class of the medical device software they are developing. Each process outcome with a corresponding safety class is a re

33、quirement in IEC 62304:2006. The process outcomes without a corresponding safety class are based only on ISO/IEC 12207:2008. These process outcomes provide additions that are beneficial when achieving the purpose of the process and could be regarded as a valuable contribution to safety-critical soft

34、ware development. The PRM may also be used to provide a common basis for different models and methods for process assessment, ensuring that the results of the assessments can be reported in a common context. Assessors who are concerned with examining medical device software processes can use the PRM

35、 as an agreed list of IEC 62304 process outcomes to inform audit check listing and reporting. The process descriptions in the PRM incorporate a statement of the purpose of the process which describes at a high level the overall objectives of performing the process, together with the set of outcomes

36、which demonstrate the successful achievement of the process purpose. These process outcomes are the software life cycle process requirements the statements of the overall goal of performing the process. In any process description, the set of process outcomes are necessary and sufficient to achieve t

37、he purpose of the process. A manufacturer of a medical device software system is required to assign a software safety class (A, B, or C) according to the possible effects on the patient, operator, or other people resulting from a hazard to which the software system contributes, described in greater

38、detail in IEC 62304:2006. The software safety classes are assigned based on severity as follows: Class A: no injury or damage to health is possible; Class B: non-serious injury is possible; Class C: death or serious injury is possible. 0.2 Organization of this technical report This TR is organized t

39、o follow the structure of IEC 62304. Annex A describes the development of the TR in greater detail. Annex B provides a mapping from IEC 62304 clauses together with their safety classes to the corresponding ISO/IEC 12207:2008 processes. The life cycle processes of the PRM for medical device software

40、development are described in terms of process name, process purpose and the corresponding process outcomes. The outcomes marked with an “ISO/IEC 12207” at the end of the outcome statement are derived from ISO/IEC 12207:2008, with no directly corresponding requirement in IEC 62304. Users of this PRM

41、who wish to examine only the IEC 62304 requirements can elect to disregard the outcomes that are based only on ISO/IEC 12207:2008.

42、 1 Scope This part of IEC 80002, which is a technical report (TR), provides the description of software life cycle processes for medical devices. The medical device software life cycle processes are derived from IEC 62304:2006, with corresponding safety classes. They have been aligned with the softw

43、are development life cycle processes of ISO/IEC 12207:2008 and are presented herein in full compliance with ISO/IEC 24774:2010. The content of these three standards provides the foundation of this TR. This TR does not address: areas already covered by existing related standards, e.g. the internation

44、al standards that relate to the four standards used to build this TR (see Bibliography); FDA guidance documents; or software development tools. This TR describes the PRM for medical device software development and is limited in scope to the life cycle processes described in IEC 62304:2006. The proce

45、ss names correspond to those of IEC 62304:2006. The mappings provided in Annex B are essential for the alignment between IEC 62304:2006 (which is based on ISO/IEC 12207:1995) and ISO/IEC 12207:2008, developed to address the detailed normative relationship between the two standards. This technical re

46、port is not intended to be used as the basis of regulatory inspection or certification assessment activities. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edi

47、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

48、ns For the purposes of this document, the terms and definitions given in IEC 62304:2006 apply. NOTE To be consistent with the requirements for developing a PRM, the guidelines set forth in ISO/IEC 24774 were followed. Having a dedicated software risk management process enables the software developer

49、s to realize the set of requirements they have to adhere to when developing software for medical devices. This PRM also enables the medical device software developers to determine the requirements necessary to develop software for a specific safety class. The PRM presented in this TR includes only the software risk management requirements of ISO 14971 that are a part of IEC 62304. The software risk management terminology is therefore derived directly from ISO 14971. For the purposes of this TR, t
