35、 as a EN ISO 15882:2008 without any modification. Introduction This International Standard provides guidance for users regarding the selection, use and interpretation of results of chemical indicators intended for use with sterilization processes employing steam, dry heat, ethylene oxide, or radiati
36、on, 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 intended primarily for the use of manufacturers of c
37、hemical 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 the requirements for validation of sterilization
38、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 sterilization. The actual use/frequency of chemical indi
39、cators 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 development of sterilization process monitors ge
40、nerally 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 appropriate use. The complexity of modern medical techno
41、logy and the wide variety of sterilization processing techniques and equipment available have made effective sterility assurance programmes more challenging than ever before. 4 DIN EN ISO 15882:2008-12 EN ISO 15882:2008 (E) 1 Scope 1.1 This International Standard provides guidance for the selection,
42、 use and interpretation of results of chemical indicators used in process definition, validation and routine monitoring and overall control of sterilization processes. This International Standard applies to indicators that show exposure to sterilization processes by means of physical and/or chemical
43、 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 action on the presence or absence of a living organism. 1.2 This International Standard does not consider indicators for use in
44、 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 combination processes, for example, washer disinfectors or CIP (cleaning in place) and SIP (sterilization in place). 2 Terms and defini
45、tions For the purposes of this document, the following terms and definitions apply. NOTE A vocabulary of terms used for sterilization of health care products is provided in ISO/TS 1113911. 2.1 chemical indicator non-biological indicator test system that reveals change in one or more pre-defined proc
