Foreword
This document (prEN 868-6:2015) has been prepared by Technical Committee CEN/TC 102 “Sterilizers for
medical purposes”, the secretariat of which is held by DIN.
This document is currently submitted to the Enquiry.
This document will supersede EN 868-6:2009.
Annex A provides details of significant technical changes between this draft European Standard and the
previous edition.
EN 868 consists of the following parts, under the general title Packaging for terminally sterilized medical
devices:
— Part 2: Sterilization wrap — Requirements and test methods;
— 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;
— Part 4: Paper bags — Requirements and test methods;
— Part 5: Sealable pouches and reels of porous materials and plastic film construction — Requirements and
test methods;
— Part 6: Paper for low temperature sterilization processes — Requirements and test methods;
— Part 7: Adhesive coated paper for low temperature sterilization processes — Requirements and test
methods;
— Part 8: Re-usable sterilization containers for steam sterilizers conforming to EN 285 — Requirements and
test methods;
— Part 9: Uncoated nonwoven materials of polyolefines — Requirements and test methods;
— Part 10: Adhesive coated nonwoven materials of polyolefines — Requirements and test methods.
In addition, ISO/TC 198 “Sterilization of health care products” in collaboration with CEN/TC 102, Sterilizers for
medical purposes has prepared the EN ISO 11607 series, Packaging for terminally sterilized medical devices.
The EN ISO 11607 series specifies general requirements for materials, sterile barrier systems and packaging
systems (Part 1) and validation requirements for forming, sealing and assembly processes (Part 2).

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
preformed 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 to 4.3 can be used to demonstrate compliance with one or more
but not all of the requirements of EN ISO 11607-1.
Paper specified in this part of the series EN 868 is intended for use in part or complete manufacture of
pouches and form and fill packs and lidding material for packs.
NOTE 1 The paper specified in this part of the EN 868 series is suitable for the manufacture of sterile barrier systems
to be used in ethylene oxide, irradiation or low temperature steam formaldehyde sterilization processes and to produce
coated paper according to EN 868–7.
NOTE 2 Paper according to EN 868–3 can also be used for these sterilization processes.
The materials specified in this part of EN 868 are intended for single use only.
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 filters, 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.

4 Requirements
4.1 General
For any material, preformed sterile barrier system or sterile barrier system, the requirements of
EN ISO 11607-1 apply.
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.
NOTE Compliance to prEN 868–6 does not automatically mean compliance to EN ISO 11607-1.
A confirmation of compliance to prEN 868-6 shall contain a statement whether EN ISO 11607-1 is covered.
4.2 Performance requirements and test methods
NOTE See Annex D for repeatability and reproducibility of the test methods: pore diameters, sulfate content, chloride
content and water repellency. For information on statement of precision and/or bias, repeatability and reproducibility of
other test methods, see Table B.1 in EN ISO 11607-1:2009/A1:2014.
4.2.1 When the paper is to be used to manufacture packaging intended to be irradiation sterilized only, it is
not necessary for it to have wet strength properties or any permeability to air, so 4.2.11, 4.2.12 and 4.2.15
need not apply.
4.2.2 No colour shall leach out of the paper. Compliance shall be tested by visual examination of a hot
aqueous extract prepared in accordance with the method given in ISO 6588-2.
