This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential reuirements of EU Directive(s).

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 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-biological 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 not 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 Scope This 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 process. 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 systems for testing sterilizers and sterilization processes. The requirements of this part of EN 867 apply to all indicator systems specified in subsequent parts of EN 867, unless the requirement is modified or added to by a subsequent part, in which case the requirement of the particular part will apply. 2 Normative references This 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 revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

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 they are designed to be used. 4.1 Process indicators Ð Class A Process 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 but may be designed to achieve their end-point reaction after exposure to sub-optimal levels of the process variable. Process indicators have a defined end-point reaction. 4.2 Indicators for use in specific tests Ð Class B These indicators are designed for use in a specific test procedure defined in the relevant sterilizer/sterilization standard. These indicators may have a graduated response or a defined end-point reaction. 4.3 Single-variable' indicators Ð Class C Single-variable' indicators are designed to monitor the attainment of the required value of one critical variable in the sterilization process. Single-variable' indicators may have a graduated response or a defined end-point reaction. 4.4 Multi-variable' indicators Ð Class D Multi-variable' indicators are designed to monitor the attainment of the required value of two or more critical variables in the sterilization process. Multi-variable' indicators may have a graduated response or a defined end-point reaction. 5 General requirements 5.1 General 5.1.1 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 maintain a formal quality system to cover all operations 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 Labelling Where a date is required on labelling or information supplied with the product, this shall be expressed in accordance with EN 28601. 5.3 Test methods The 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 Marking 5.4.1 Each indicator 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 ÊC. Where the size or format of the indicator does not permit this information to be stated in a font of 6 characters per centimetre, or larger, the information shall be provided on the label and/or instructions for use. 5.4.2 Abbreviated descriptions of the process, if used, shall be in accordance with the following symbols: STEAM ± all steam sterilization processes DRY ± all dry heat sterilization processes EO ± all ethylene oxide sterilization processes IRRAD ± all ionizing radiat
