21、dard, either by publication of an identical text or by endorsement, at the latest by August 1997, and conflicting national standards shall be withdrawn at the latest by August 1997.This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free
22、Trade Association, and supports essential reuirements of EU Directive(s).According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Icel
23、and, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.ContentsPageForeword 2Introduction 31 Scope 32 Normative references 33 Definitions 34 Classification 45 General requirements 46 Labelling and instructions for use 5Annex A (informative)
24、Bibliography 6IntroductionEuropean Standards for sterilizers (EN 285 and other standards in preparation by CEN/TC 102) and for the validation and process control of sterilization (EN 550, EN 552 and EN 554) describe performance tests for sterilizers and methods of validation and routine control, res
25、pectively.This standard specifies the general requirements for non-biological indicators and subsequent parts specify the particular requirements for non-biological indicators for particular applications and for defined tests of particular sterilization processes. The use of the indicators specified
26、 in this standard are described in EN 285, EN 550, EN 552 and EN 554.The non-biological indicators specified in this standard are not intended for use in any process other than that specified. The use of an inappropriate indicator can give dangerously misleading results.The performance of a non-biol
27、ogical indicator can be affected by the conditions of storage prior to use, the methods of use, and the conditions of storage after exposure to the process. For these reasons, the recommendations of the manufacturer for storage and use should be followed precisely. Non-biological indicators should n
28、ot be used beyond any expiry date stated by the manufacturer.When a physical and/or chemical variable of a sterilizing process is outside its specified limits, a sterilization cycle should always be regarded as unsatisfactory, irrespective of the results obtained from the non-biological indicators.1
29、 ScopeThis European Standard specifies general requirements for indicators which are not dependent for their action on the presence or absence of living organisms, and which are used to monitor the presence or attainment of one or more of the variables required for a satisfactory sterilization proce
30、ss.This standard does not specify requirements for the use of biological systems.NOTE. Biological test systems are regarded as those tests which are dependent for their interpretation on the demonstration of viability of an organism. Test systems of this type are considered in EN 866 Biological syst
31、ems for testing sterilizers and sterilization processes.The requirements of this part of EN 867 apply to all indicator systems specified in subsequent parts ofEN 867, unless the requirement is modified or added to by a subsequent part, in which case the requirement of the particular part will apply.
32、2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisio
33、ns of any of these publications apply to this European Standard onlywhen incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.EN 28601Data elements and interchangeformats Information interchange Representation of dates and time
34、s(ISO 8601 : 1988 and technical corrigendum 1 : 1991)3 DefinitionsFor the purposes of this European Standard the following definitions apply:3.1 graduated responseA progressive visible change occurring on exposure to one or more process variables allowing assessment of the level achieved.3.2 defined
35、 end-pointThe visible change occurring after exposure to the specified variable(s) at a level equal to or greater than that specified for the indicator.3.3 indicatorThe indicator system in the form in which it is intended to be used.3.4 indicator reagentThe active ingredient or combination of ingred
36、ients before conversion into the indicator.3.5 indicator systemThe combination of the indicator reagent and its substrate.4 ClassificationNOTE. In the subsequent parts of this standard indicators are classified by their intended use and, within each of these classifications, by the process for which
37、 they are designed to be used.4.1 Process indicators Class AProcess indicators are intended for use with individual packs of product intended to be sterilized to demonstrate that the pack has been exposed to the process. They may be designed to react to one or more of the critical process variables
38、but may be designed to achieve their end-point reaction after exposure tosub-optimal levels of the process variable.Process indicators have a defined end-point reaction.4.2 Indicators for use in specific tests Class BThese indicators are designed for use in a specific test procedure defined in the r
39、elevant sterilizer/sterilization standard.These indicators may have a graduated response or a defined end-point reaction.4.3 Single-variable indicators Class CSingle-variable indicators are designed to monitor the attainment of the required value of one critical variable in the sterilization process
40、.Single-variable indicators may have a graduated response or a defined end-point reaction.4.4 Multi-variable indicators Class DMulti-variable indicators are designed to monitor the attainment of the required value of two or more critical variables in the sterilization process.Multi-variable indicato
41、rs may have a graduated response or a defined end-point reaction.5 General requirements5.1 General5.1.1 The requirements of this section shall apply to all indicators unless specifically excluded or amended in a subsequent part of this standard.5.1.2 The manufacturer shall establish, document and ma
42、intain a formal quality system to cover alloperations required by this standard.NOTE. EN ISO 9001 and EN ISO 9002 and of the EN 45000 series describe requirements for quality systems for manufacture and testing.5.2 LabellingWhere a date is required on labelling or information supplied with the produ
43、ct, this shall be expressed in accordance with EN 28601.5.3 Test methodsThe test methods specified in this standard are reference methods. When alternative methods are used routinely these shall be defined, validated and have known correlation with the reference method.5.4 Marking5.4.1 Each indicato
44、r shall be clearly marked with the type of process for which it is intended to be used and the class of indicator as defined in this standard(see 4.1 to 4.4 inclusive).If the use of the indicator is limited to specific sterilization cycles, this information shall also be stated or coded on the indicator, e.g. steam 15 min 121 C.Where the size
