24、N ISO/TS 17665-2:2009ISO/TS 17665-2:2009(E) iv ISO 2009 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO t

25、echnical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clos

26、ely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draf

27、t International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requireme

28、nt for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members o

29、f the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three ye

30、ars in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standar

31、d or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 17665-2 was prepared by Technical Committee ISO/TC 198, Sterilization of he

32、alth care products. ISO 17665 consists of the following parts, under the general title Sterilization of health care products Moist heat: Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices Part 2: Guidance on the application of ISO

33、17665-1 Technical Specification DD CEN ISO/TS 17665-2:2009ISO/TS 17665-2:2009(E) ISO 2009 All rights reserved vIntroduction The guidance given in this Technical Specification is not intended as a checklist for assessing compliance with ISO 17665-1. This guidance is intended to assist in obtaining a

34、uniform understanding and implementation of ISO 17665-1 by providing explanations and acceptable methods for achieving compliance with specified requirements. It highlights important aspects and provides examples. Methods other than those given in this guidance may be used. However, the use of alter

35、native methods has to be demonstrated to be effective in achieving compliance with ISO 17665-1. The main body of this document is applicable to all settings where moist heat sterilization is carried out. The annexes to this guidance document also specify detailed means of implementing the requiremen

36、ts of ISO 17665-1 and represent current best practices. The numbering of the clauses in the main body of this Technical Specification corresponds to that in ISO 17665-1. Medical devices reprocessed in health care facilities include a wide variety of product with varying levels of bioburden. Appropri

37、ate and thorough cleaning and, where necessary for safe handling, decontamination processes are essential prior to presenting product for sterilization. Mixed product loads are common in healthcare facilities with throughput volumes dictated by historical and predicted demand for sterile product. He

38、alth care facilities do not normally specify sterilization processes for any individual medical device. Also, it is impractical for health care facilities to determine bioburden on a medical device. It is important that specified instruments be disassembled before decontamination and thoroughly insp

39、ected after completion of the sterilization process. Reassembly and assessment of functionality are also needed. Therefore, the medical device manufacturers instructions (see ISO 1766423) should be followed for all aspects of cleaning, disinfection, packaging and sterilization. Many devices can be f

40、ully immersed and can be washed and disinfected in automated equipment (see ISO 1588319-22). For devices that cannot be fully immersed and that cannot tolerate thermal decontamination, alternative methods of disinfection should be used to ensure safe handling. Such procedures and policies should be

41、in place to ensure that medical devices undergo appropriate reprocessing. Particular attention needs to be paid to the drying and storage of sterile medical devices. Requirements for packaging of medical devices are covered in ISO 11607-18and ISO 11607-29. If multiple sterilization cycles can lead t

42、o degradation and limit the useful life of a medical device, the manufacturer will specify the number of reprocessing cycles that can normally be tolerated. When selecting a medical device, priority should be given to properties such as ease of cleaning and disassembly. Additional guidance specific

43、to health care is offered in Annex D of this Technical Specification.

44、 Scope This Technical Specification provides general guidance on the development, validation and routine control of moist heat sterilization processes and is intended to explain the requirements set forth in ISO 17665-1. The guidance given in this Technical Specification is provided to promote good

45、practice related to moist heat sterilization processes and to assist those developing and validating a moist heat sterilization process according to ISO 17665-1. NOTE 1 The structure of the main body of this ISO Technical Specification (Clauses 1 to 12) corresponds to the structure of ISO 17665-1, s

46、o that the guidance given under a particular clause or subclause of this part of ISO 17665 applies to the requirements given in the corresponding clause or subclause of ISO 17665-1. For example, guidance for subclause 5.2 of ISO 17665-1:2006 is given in 5.2. This guidance is provided in addition to

47、the guidance given in ISO 17665-1:2006, Annex A. See also Annexe E. NOTE 2 Special considerations specific to sterilization processes performed in health care facilities are given in Annex D. 2 Normative references The following referenced documents are indispensable for the application of this docu

48、ment. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
