23、ational 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 technical committees. Each member body interested in a subject for which a technical committee has b

24、een 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 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical sta

25、ndardization. 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. Draft International Standards adopted by the technical committees are circulated to the member bodies f

26、or voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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 a

27、ll such patent rights. ISO 15882 was prepared by Technical Committee ISO/TC 198, Sterilization of health care products.

29、oying steam, dry heat, ethylene oxide, or radiation, low temperature steam and formaldehyde (LTSF), or vapourized hydrogen peroxide as documented in ISO 11140-1 13. The ISO 11140 12, 13, 14, 15, 16series of standards specifies performance requirements for chemical indicators. These standards are int

30、ended primarily for the use of manufacturers of chemical indicators. The guidance in this document is of a general nature; chemical indicators do not, of themselves, constitute a comprehensive monitoring programme with regard to the sterilization of health care products. Users attention is drawn to

31、the requirements for validation of sterilization processes specified in ISO 14937 18for general processes, the ISO 17665 19, 20series for moist heat sterilization, the ISO 11135 5, 6series for ethylene oxide sterilization, ISO 11137-1 7for radiation sterilization and ISO 20857 22for dry heat sterili

32、zation. The actual use/frequency of chemical indicators might be regulated by international and or national standards as well as by local regulatory authorities. The need for convenient and rapid means of detecting sterilization problems occurring during sterilization processes has brought about the

33、 development of sterilization process monitors generally referred to as “chemical indicators.” In this International Standard, users will find guidance on selection of the correct chemical indicator for their particular sterilization process and critical parameters as well as guidance on its appropr

34、iate use. The complexity of modern medical technology and the wide variety of sterilization processing techniques and equipment available have made effective sterility assurance programmes more challenging than ever before.

36、for selection, use and interpretation of results 1 Scope 1.1 This International Standard provides guidance for the selection, use and interpretation of results of chemical indicators used in process definition, validation and routine monitoring and overall control of sterilization processes. This In

37、ternational Standard applies to indicators that show exposure to sterilization processes by means of physical and/or chemical change of substances, and which are used to monitor one or more of the variables required of a sterilization process. These chemical indicators are not dependent for their ac

38、tion on the presence or absence of a living organism. 1.2 This International Standard does not consider indicators for use in those processes that rely on physical removal of microorganisms, e.g. filtration. 1.3 This International Standard is not intended to apply to indicators for use in combinatio

39、n processes, for example, washer disinfectors or CIP (cleaning in place) and SIP (sterilization in place). 2 Terms and definitions For the purposes of this document, the following terms and definitions apply.
