1.1    This document specifies the general criteria for tests of sterility on medical devices that have been exposed to a treatment with the sterilizing agent which has been reduced relative to that anticipated to be used in routine sterilization processing. These tests are intended to be performed when defining, validating or maintaining a sterilization process.
1.2    This document is not applicable to:
a)    sterility testing for routine release of product that has been subjected to a sterilization process,
b)    performing a test for sterility (see 3.12),
NOTE 1    The performance of a) or b) is not a requirement of ISO 11135, ISO 11137-1, ISO 11137-2, ISO 14160, ISO 14937, ISO 17665-1 or ISO 20857.
c)    test of sterility or test for sterility for demonstration of product shelf life, stability and/or package integrity, and
d)    culturing of biological indicators or inoculated products.
NOTE 2    Guidance on culturing biological indicators is included in ISO 11138-7.

1.1   Dieses Dokument legt die allgemeinen Kriterien für Prüfungen der Sterilität von Medizinprodukten fest, die einer Behandlung mit dem sterilisierenden Agens unterzogen wurden, die im Vergleich zu derjenigen, die voraussichtlich bei routinemäßigen Sterilisationsverfahren angewendet wird, reduziert wurde. Diese Prüfungen sind vorgesehen, wenn ein Sterilisationsverfahren definiert, validiert oder aufrechterhalten wird.
1.2   Dieses Dokument gilt nicht für:
a)   die Sterilitätsprüfung für die Routinefreigabe eines Produkts, das einem Sterilisationsverfahren unterzogen wurde;
b)   das Durchführen einer Prüfung auf Sterilität (siehe 3.14);

Annex ZA
(informative)
Relationship between this European Standard and the Essential
Requirements of EU Directive 90/385/EEC on active implantable medical
devices [OJ L 189] aimed to be covered
This European standard has been prepared under a Commission’s standardisation request M/023 to
provide one voluntary means of conforming to essential requirements of Council Directive 90/385/EEC
of 20 June 1990 on the approximation of the laws of the Member States relating to active implantable
medical devices [OJ L 189].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding Essential Requirements
of that Directive and associated EFTA regulations.
NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk
management process needs to be in compliance with 90/385/EEC, as amended by 2007/47/EC. This means that
risks have to be reduced ‘as far as possible’, ‘to a minimum’, ‘to the lowest possible level’, ‘minimized’ or ‘removed’,
according to the wording of the corresponding essential requirement.
NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with essential
requirements 1, 4, 5, 8, 9 and 10of the Directive.
NOTE 3 When an Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this
European Standard.
