(Main + Amendment)Sterilization - Steam sterilizers - Large sterilizers
Sterilization - Steam sterilizers - Large sterilizers
1.1 This European Standard specifies requirements and the relevant tests for large steam sterilizers primarily used in health care for the sterilization of medical devices and their accessories contained in one or more sterilization modules. The test loads described in this European Standard are selected to represent the majority of loads (i.e. wrapped goods consisting of metal, rubber and porous materials) for the evaluation of general purpose steam sterilizer for medical devices. However, specific loads (e.g. heavy metal objects or long and/or narrow lumen) will require the use of other test loads.
Large steam sterilizers can also be used during the commercial production of medical devices.
1.2 This European Standard is not applicable to steam sterilizers designed to process a size of load less than one sterilization module or having a chamber volume less than 60 l.
1.3 This European Standard does not describe a quality assurance system for the control of all stages of the manufacture of the sterilizer.
NOTE Attention is drawn to the standards for quality management systems e.g. EN ISO 13485.
1.4 Planning and design of products applying to this European Standard should consider the environmental impact from the product during its life cycle. Environmental aspects are addressed in Annex A.
NOTE Additional aspects of environmental impact are addressed in EN ISO 14971.
Sterilisation - Dampf-Sterilisatoren - Groß-Sterilisatoren
1.1 Diese Europäische Norm legt Anforderungen und die entsprechenden Prüfungen für Dampf-Groß-
Sterilisatoren fest, die überwiegend im Gesundheitswesen zur Sterilisation von Medizinprodukten und ihres
Zubehörs in einer oder mehreren Sterilisiereinheiten verwendet werden. Die in dieser Europäischen Norm
beschriebenen Prüfbeladungen wurden gewählt, um bei der Beurteilung der für allgemeine Zwecke dienenden
Dampf-Sterilisatoren für Medizinprodukte für die Mehrzahl der Beladungen repräsentativ zu sein (d. h.
verpackte Güter aus Metall, Gummi und porösen Materialien). Besondere Beladungen (z. B. schwere
Metallgegenstände oder Hohlkörper mit langem und/oder engem Lumen) erfordern jedoch die Verwendung
anderer Prüfbeladungen.
Dampf-Groß-Sterilisatoren können auch bei der gewerblichen Herstellung von Medizinprodukten verwendet
werden.
1.2 Diese Europäische Norm ist nicht für Dampf-Sterilisatoren anwendbar, die für die Behandlung einer
Beladung ausgelegt sind, die kleiner als eine Sterilisiereinheit ist, oder die ein Kammervolumen von weniger
als 60 l aufweisen.
1.3 Diese Europäische Norm beschreibt nicht ein Qualitätssicherungssystem für die Überwachung aller
Phasen der Herstellung von Sterilisatoren.
ANMERKUNG Es wird auf die Normen für Qualitätsmanagementsysteme verwiesen, z. B. EN ISO 13485.
1.4 Bei der dem Lebenszyklus entsprechenden Planung und Gestaltung von Produkten, für die diese
Europäische Norm gilt, sollten die vom Produkt ausgehenden Umweltauswirkungen berücksichtigt werden.
Umweltgesichtspunkte werden in Anhang A behandelt.
ANMERKUNG Zusätzliche Gesichtspunkte der Auswirkungen auf die Umwelt werden in EN ISO 14971 behandelt.
Stérilisation - Stérilisateurs à la vapeur d'eau - Grands stérilisateurs
1.1 La présente Norme européenne spécifie les exigences et les essais relatifs aux grands stérilisateurs à la
vapeur d'eau utilisés essentiellement dans le domaine de la santé, pour la stérilisation de dispositifs médicaux et
de leurs accessoires dans une ou plusieurs unités de stérilisation. Les charges d’essai décrites dans la présente
Norme européenne ont été sélectionnées afin de représenter la majorité des charges (par exemple, les produits
emballés en métal, en caoutchouc ou en matériaux poreux) en vue de l'évaluation des stérilisateurs à la vapeur
d'eau à usage général utilisés pour les dispositifs médicaux. Cependant, pour certaines charges spécifiques (par
exemple, objets métalliques lourds ou objets à cavités extrêmement longues (corps creux)), des charges d’essai
différentes seront nécessaires.
Les grands stérilisateurs à la vapeur d'eau peuvent être également utilisés pour la production commerciale de
dispositifs médicaux.
1.2 La présente Norme européenne n’est pas applicable aux stérilisateurs à la vapeur d'eau conçus pour
stériliser une charge de taille inférieure à une unité de stérilisation ou de volume inférieur à 60 l.
1.3 La présente Norme européenne ne décrit pas un système d'assurance qualité pour le contrôle de toutes les
étapes de la fabrication du stérilisateur.
NOTE L'attention est attirée sur les normes pour les systèmes de management de la qualité, par exemple l’EN ISO 13485.
1.4 Il convient que la planification et la conception des produits traités dans la présente Norme européenne
tiennent compte de l’impact environnemental du produit durant son cycle de vie. Les aspects environnementaux
sont traités à l’Annexe A.
NOTE D’autres aspects environnementaux sont abordés dans l’EN ISO 14971.

medical purposes”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by September 2008 and conflicting national standards shall be withdrawn at the latest
by November 2008.
This document includes Amendment 1, approved by CEN on 2008-02-04.
This document supersedes !EN 285:2006".
The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ".
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
