19、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 been established has the right to be represented on that committee. International organizations, go
20、vernmental 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 standardization. International Standards are drafted in accordance with the rules given in the ISO/IE
21、C 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 for voting. Publication as an International Standard requires approval by at least 75 % of the memb
22、er 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 all such patent rights. ISO 11138-1 was prepared by Technical Committee ISO/TC 198, Sterilization o
23、f health care products. This second edition cancels and replaces the first edition (ISO 11138-1:1994), which has been technically revised. ISO 11138 consists of the following parts, under the general title Sterilization of health care products Biological indicators: Part 1: General requirements Part
24、 2: Biological indicators for ethylene oxide sterilization processes Part 3: Biological indicators for moist heat sterilization processes Part 4: Biological indicators for dry heat sterilization processes Part 5: Biological indicators for low-temperature steam and formaldehyde sterilization processe

26、quirements for the manufacture of biological indicators including inoculated carriers and suspensions intended for use in validation and monitoring of sterilization processes. Subsequent parts of ISO 11138 provide additional specific requirements for biological indicators for defined sterilization p
27、rocesses. A graphic description of a biological indicator and its components is presented in Annex F. The presentation includes the two types of biological indicator which are covered by ISO 11138. This shows that inoculated carriers can be presented directly to the sterilizing agent without prior p
28、ackaging, or included in a primary package that permits access by the sterilizing agent. The resistance characteristics depend on the type of test organism, its numbers, the method of preparation and the effects of the primary package. Advice on selection, use and interpretation of results of biolog
29、ical indicators can be found in ISO 141617. For any individual sterilization process, including those covered in subsequent parts of ISO 11138, the resistance of the biological indicator will also depend on its microenvironment during testing. In theory, this could lead to an infinite variation in t
30、he preparation of biological indicators. Moreover, a sterilization process could be manipulated in infinite variety to suit each possible set of conditions to which products could be exposed. It has therefore been routine practice to manufacture biological indicators that, when exposed to a set of c
31、onditions in a defined sterilization process, provide resistance characteristics expressed as D values and, where relevant, z values. Such values are set out in the subsequent parts of ISO 11138. ISO 11138, parts 1 to 5 represent the current “state-of-the-art” according to the experts representing m
32、anufacturers, users and regulatory authorities involved in developing this International Standard. Biological indicators for specific sterilization processes not covered by reference test conditions in subsequent parts of ISO 11138 should comply with the general requirements in this part, including
33、the resistance testing procedures. Such biological indicators might not be well enough described, or might be used for novel sterilization processes, or might be represented by isolated bioburden microorganisms. If microorganisms other than risk group 1 (WHO,199327) are included in these biological
34、indicators, the appropriate containment and safety levels must be met. Standards exist providing requirements for the validation and control of sterilization processes (see Bibliography). NOTE Some countries or regions might have published other standards covering requirements for sterilization or b
35、iological indicators (see Bibliography).

37、of biological indicators, including inoculated carriers and suspensions, and their components, to be used in the validation and routine monitoring of sterilization processes. 1.1.2 This part of ISO 11138 specifies basic and common requirements that are applicable to all subsequent parts of ISO 11138
38、. Requirements for biological indicators for particular specified processes are provided in the subsequent parts of ISO 11138. If no specific subsequent part is provided, this part applies. NOTE National or regional regulations may apply. 1.2 Exclusions This part of ISO 11138 does not apply to micro
39、biological test systems for processes that rely on physical removal of microorganisms, e.g. filtration processes or processes that combine physical and/or mechanical removal with microbiological inactivation, such as use of washer disinfectors or flushing and steaming of pipelines. This part of ISO
40、11138, however, could contain elements relevant to such microbiological test systems. 2 Normative references The following referenced documents are indispensable for the application of this document.
