Packaging for terminally sterilized medical devices - Part 3: Paper for use in the manufacture of paper bags (specified in EN 868-4) and in the manufacture of pouches and reels (specified in EN 868-5) - Requirements and test methods

This draft European Standard provides test methods and values for paper, used in the manufacture of paper bags (specified in EN 868-4) and in the manufacture of pouches and reels (specified in EN 868-5) used as sterile barrier systems and/or packaging systems that are intended to maintain sterility of terminally sterilized medical devices to the point of use.
The need for a protective packaging may be determined by the manufacturer and the user.
This part of EN 868 only introduces performance requirements and test methods that are specific to the products covered by this part of EN 868 but does not add or modify the general requirements specified in EN ISO 11607-1.
As such, the particular requirements in 4.2 can be used to demonstrate compliance with one or more but not all of the requirements of EN ISO 11607-1.
When additional materials are used inside the sterile barrier system in order to ease the organization, drying or aseptic presentation (e.g. inner wrap, container filter indicators, packing lists, mats, instrument organizer sets, tray liners or an additional envelope around the medical device) then other requirements, including the determination of the acceptability of these materials during validation activities, may apply.
The materials specified in this part of EN 868 are intended for single use only.
NOTE   Applicable sterilization methods are specified by the manufacturer.

Verpackungen für in der Endverpackung zu sterilisierende Medizinprodukte - Teil 3: Papier zur Herstellung von Papierbeuteln (festgelegt in EN 868-4) und zur Herstellung von Klarsichtbeuteln und -schläuchen (festgelegt in EN 868-5) - Anforderungen und Prüfverfahren

Dieser europäische Norm-Entwurf enthält Prüfverfahren und Werte für Papier zur Herstellung von Papierbeuteln (festgelegt in EN 868 4) und zur Herstellung von Klarsichtbeuteln und  schläuchen (festgelegt in EN 868 5), die dazu vorgesehen sind, als Sterilbarrieresysteme und/oder Verpackungssysteme die Sterilität von in der Endverpackung sterilisierten Medizinprodukten bis zum Anwendungszeitpunkt zu erhalten.
Die Erfordernis für eine Schutzverpackung darf durch den Hersteller und den Anwender bestimmt werden.
Dieser Teil von EN 868 enthält lediglich Leistungsanforderungen und Prüfverfahren, die spezifisch für die Produkte nach diesem Teil von EN 868 sind, ergänzt oder modifiziert jedoch nicht die in EN ISO 11607 1 festgelegten allgemeinen Anforderungen.
Die besonderen Anforderungen nach 4.2 können daher verwendet werden, um Übereinstimmung mit einer oder mehreren Anforderung(en) - aber nicht mit allen Anforderungen - der EN ISO 11607 1 nachzuweisen.
Werden zusätzliche Materialien im Sterilbarrieresystem verwendet, um die Organisation, die Trocknung oder die aseptische Präsentation zu erleichtern (z. B. Innenverpackung, Filter für Sterilisier¬behälter, Indikatoren, Verpackungslisten, Unterlagen, Einsätze für Instrumente, Fächer oder eine zusätzliche Umhüllung für das Medizinprodukt), dann können andere Anforderungen, einschließlich der Bestimmung der Eignung dieser Materialien im Rahmen von Validierungstätigkeiten, gelten.
Die nach diesem Teil von EN 868 festgelegten Materialien sind nur für den einmaligen Gebrauch vorgesehen.
ANMERKUNG   Anwendbare Sterilisationsverfahren werden durch den Hersteller festgelegt.

Matériaux et systèmes d'emballage pour les dispositifs médicaux stérilisés au stade terminal - Partie 3 : Papier utilisé dans la fabrication des sacs en papier (spécifiés dans l'EN 868-4) et dans la fabrication de sachets et gaines (spécifiés dans l'EN 868-5) - Exigences et méthodes d'essai

Le présent projet de Norme européenne fournit des méthodes d’essai et des valeurs applicables au papier utilisé dans la fabrication des sacs en papier (spécifiés dans l’EN 868-4) et des sachets et gaines (spécifiés dans l’EN 868-5) utilisés comme systèmes de barrière stérile et/ou comme systèmes d’emballage destinés à maintenir l’état de stérilité des dispositifs médicaux, stérilisés au stade terminal, jusqu’à leur utilisation.
La nécessité d’un emballage de protection peut être déterminée par le fabricant et l’utilisateur.
La présente partie de l’EN 868 présente uniquement les exigences de performance et les méthodes d’essai spécifiques aux produits couverts par la présente partie de l’EN 868, mais elle n'ajoute pas ou ne modifie pas les exigences générales spécifiées dans l’EN ISO 11607-1.
En conséquence, les exigences particulières mentionnées en 4.2 peuvent être utilisées pour démontrer la conformité à une ou plusieurs exigences de l’EN ISO 11607-1, mais pas à la totalité de ces exigences.
En cas d'utilisation de matériaux complémentaires à l’intérieur du système de barrière stérile de manière à faciliter le rangement, le séchage ou la présentation aseptique (par exemple, enveloppe interne, filtre de conteneur, indicateurs, inventaires d’emballage, matelas de support silicone ou autres plastiques, kits d’organisation des instruments médicaux, fonds de protection de panier ou une enveloppe supplémentaire contenant le dispositif médical), d’autres exigences peuvent alors s’appliquer, y compris la détermination de l’acceptabilité de ces matériaux lors des activités de validation.
Les matériaux spécifiés dans la présente partie de l’EN 868 sont destinés exclusivement à un usage unique.
NOTE   Les méthodes de stérilisation applicables sont spécifiées par le fabricant.

Introduction
The EN ISO 11607 series consists of two parts under the general title Packaging for terminally sterilized
medical devices. Part 1 of this series specifies general requirements and test methods for materials,
preformed sterile barrier systems, sterile barrier systems and packaging systems that are intended to maintain
sterility of terminally sterilized medical devices to the point of use. Part 2 of this series specifies validation
requirements for forming, sealing and assembly processes.
Every sterile barrier system needs to fulfil the requirements of EN ISO 11607-1.
The EN 868 series can be used to demonstrate compliance with one or more of the requirements specified in
EN ISO 11607-1.
CEN/TC 102/WG 4 also appreciates the initiatives of CEN with regard to the minimization of adverse
environmental impacts by standards. It was agreed that this subject should be given priority during the next
edition of the EN ISO 11607 series that is the basic reference for all parts of the EN 868 series.

1 Scope
This draft European Standard provides test methods and values for paper, used in the manufacture of paper
bags (specified in EN 868-4) and in the manufacture of pouches and reels (specified in EN 868-5) used as
sterile barrier systems and/or packaging systems that are intended to maintain sterility of terminally sterilized
medical devices to the point of use.
The need for a protective packaging may be determined by the manufacturer and the user.
This part of EN 868 only introduces performance requirements and test methods that are specific to the
products covered by this part of EN 868 but does not add or modify the general requirements specified in
EN ISO 11607-1.
As such, the particular requirements in 4.2 can be used to demonstrate compliance with one or more but not
all of the requirements of EN ISO 11607-1.
When additional materials are used inside the sterile barrier system in order to ease the organization, drying
or aseptic presentation (e.g. inner wrap, container filter indicators, packing lists, mats, instrument organizer
sets, tray liners or an additional envelope around the medical device) then other requirements, including the
determination of the acceptability of these materials during validation activities, may apply.
The materials specified in this part of EN 868 are intended for single use only.
NOTE Applicable sterilization methods are specified by the manufacturer.
