Sterilization of medical devices - Low temperature steam and formaldehyde - Requirements for development, validation and routine control of a sterilization process for medical devices (ISO 25424:2009)

ISO 25424:2009 specifies requirements for the development, validation and routine control of a Low Temperature Steam and Formaldehyde (LTSF) sterilization process for medical devices.
ISO 25424:2009 is intended to be applied by process developers, manufacturers of sterilization equipment, manufacturers of medical devices to be sterilized and the organizations with responsibility for sterilizing medical devices.
ISO 25424:2009 covers sterilization processes that use a mixture of low temperature steam and formaldehyde as sterilant, and which are working below ambient pressure only.

Sterilisation von Medizinprodukten - Niedertemperatur-Dampf- Formaldehyd - Anforderungen an die Entwicklung, Validierung und Routineüberwachung von Sterilisationsverfahren für Medizinprodukte (ISO 25424:2009)

1.1 Einbezogene Verfahren 1.1.1 Diese Europäische Norm legt Anforderungen für die Entwicklung, Validierung und Routine-
überwachung eines Sterilisationsverfahrens mit Niedertemperatur-Dampf-Formaldehyd (NTDF) für Medizin-
produkte fest.
ANMERKUNG Obgleich der Anwendungsbereich dieser Norm auf Medizinprodukte begrenzt ist, legt sie Anforderungen fest und liefert Anleitungen, die für andere Produkte und Geräte gelten können.
1.1.2 Diese Europäische Norm ist dazu vorgesehen, von Verfahrensentwicklern, Herstellern von Sterilisa-
tionsausrüstungen, Herstellern zu sterilisierender Medizinprodukte und von Organisationen angewendet zu
werden, die Verantwortung für die Sterilisation von Medizinprodukten haben (siehe EN ISO 14937:2000,
Tabelle E.1).
1.1.3 Diese Europäische Norm bezieht sich auf Sterilisationsverfahren, bei denen ein Gemisch von
Niedertemperatur-Dampf und Formaldehyd als Sterilisiermittel verwendet wird, und die nur unterhalb des Umgebungsdrucks betrieben werden.
1.2 Nicht in den Anwendungsbereich fallende Gesichtspunkte
1.2.1 Es sollte nicht vorausgesetzt werden, dass entsprechend den Anforderungen dieser Norm validierte und überwachte Sterilisationsverfahren bei der Inaktivierung der Verursacher spongiformer Enzephalopathien
wie Scrapie, bovine spongiforme Enzephalopathie und Creutzfeldt-Jakob-Krankheit wirksam sind. In bestimm-
ten Ländern sind spezifische Empfehlungen für die Behandlung von möglicherweise mit diesen Erregern kontaminierten Materialien erarbeitet worden.
1.2.2 Diese Norm legt keine Anforderungen zur Kennzeichnung eines Medizinprodukts als „STERIL“ fest.
Solche Anforderungen sind in EN 556-1 angegeben.
1.2.3 Diese Norm legt kein Qualitätsmanagementsystem für die Überwachung aller Stufen der Herstellung von Medizinprodukten fest.
ANMERKUNG Es ist keine Anforderung dieser Norm, dass ein vollständiges Qualitätsmanagementsystem während der Herstellung oder Wiederaufbereitung vorhanden ist, aber auf jene Elemente eines solchen Systems, die gefordert werden, erfolgen an den entsprechenden Stellen im Text normative Verweisungen. Zu beachten sind die Normen für
Qualitätsmanagementsysteme (siehe EN ISO 13485), die alle Stufen der Herstellung oder Wiederaufbereitung von Medizinprodukten einschließlich des Sterilisationsverfahrens lenken. Eine weitere Anleitung wird in EN ISO 14937:2000, E.2 gegeben.
1.2.4 Diese Norm legt keine Anforderungen an den Arbeitsschutz fest, die mit Gestaltung und Betrieb von NTDF-Sterilisationsanlagen zusammenhängen.
ANMERKUNG 1 Sicherheitsanforderungen für Sterilisatoren sind in EN 61010-2-040 festgelegt.
ANMERKUNG 2 Es wird auch darauf hingewiesen, dass in einigen Ländern Bestimmungen bestehen, in denen Sicher-
heitsanforderungen festgelegt sind.
1.2.5 Diese Europäische Norm behandelt keine Analyseverfahren zur Bestimmung von Konzentrationen
oder Rückständen von Formaldehyd und/oder dessen Reaktionsprodukten.
ANMERKUNG 1 Zu beachten ist EN 14180.
ANMERKUNG 2 Es wird darauf hingewiesen, dass in einigen Ländern möglicherweise Bestimmungen bestehen, in denen Grenzwerte für die Konzentration von Formaldehydrückständen auf Medizinprodukten und Produkten festgelegt sind.
1.2.6 Diese Europäische Norm behandelt keine Vorbereitungsmaßnahmen, die vor der Sterilisation
erforderlich sein können wie Reinigung, Desinfektion und Verpackung.
ANMERKUNG Für wieder sterilisierbare Medizinprodukte sollten der bzw. die Hersteller dieser Produkte Angaben über die Vorbereitungsmaßnahmen zur Verfügung stellen (siehe EN ISO 17664).

ISO 25424:2009(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(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, governmental 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/IEC 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 member 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 25424 was prepared by CEN (as EN 15424:2007) and is submitted for approval under a special “fast-
track procedure”, by Technical Committee ISO/TC 198, Sterilization of health care products, in parallel with its
approval by the ISO member bodies.
For the purposes of this International Standard, the CEN annex regarding the fulfilment of European Council
Directives has been removed.
