European foreword
This document (prEN 868-6:2024 has been prepared by Technical Committee CEN/TC 102 “Sterilizers
and associated equipment for processing of medical devices”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 868-6:2017.
This document includes the following significant technical changes with respect to EN 868-6:2017:
a) The document was renumbered to limit the list numbering to 3 levels only for better readability.
b) Clause 4 “General requirements” was aligned slightly revised for clarity and aligned with the other
parts of EN 868 series and a statement was added clarifying when acceptance criteria apply.
c) Clause 6 “Sterilization compatibility” was added and aligned with the other parts of EN 868 series.
d) Clause 8 “Environmental declarations” was added, aligned with the other parts of EN 868 series.
e) List of major changes were moved to Foreword, thus Annex A was deleted.
f) New Clause “Environmental aspects for testing” was added to each test method in Annexes A – C.
g) New Annex E regarding environmental aspects was added.
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 and associated equipment for processing of medical devices” 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 of standards 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.
General requirements for all types of sterile barrier systems are provided by EN ISO 11607-1.
The EN 868 series of standards have been developed mainly for materials and sterile barrier systems
used in health care facilities sterilization processes. Materials complying with part 6 of the EN 868 series
can also be used for industrial sterilization. The EN 868 series of standards can be used to demonstrate
compliance with one or more of the requirements specified in EN ISO 11607-1.
Considering CEN Guide 4 [1] and the CEN environmental checklists, this revision has been complemented
with a new annex with guidance to encourage users to also include environmental aspects when applying
the EN 868 series of standards with the objective to minimize the environmental impact. Environmental
aspects have also been included into the description of test methods with the same objective.
1 Scope
This document specifies test methods and values for paper used in the manufacture of single-use
preformed sterile barrier systems and/or packaging systems for terminally sterilized medical devices by
means of low temperature sterilization processes.
Other than the general requirements as specified in EN ISO 11607-1 and EN ISO 11607-2 [2], this part of
EN 868 specifies materials, test methods and values that are specific to the products covered by this
document.

4 General requirements
4.1 For any material, preformed sterile barrier system or sterile barrier system, the requirements of
EN ISO 11607-1 shall apply.
NOTE 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, can apply.
4.2 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 Clause 5 can be used to demonstrate compliance with one or more
but not all of the requirements of EN ISO 1160
