general requirements for materials, sterile barrier systems and packaging systems (Part 1) and
validation requirements for forming, sealing and assembly processes (Part 2).
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,

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.
General requirements for all types of sterile barrier systems are provided by 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 European Standard specifies test methods and values for materials for sterile barrier systems
and/or packaging systems that are intended to maintain sterility of terminally sterilized medical
devices to the point of use.
Other than the general requirements as specified in EN ISO 11607-1 and EN ISO 11607-2 this part of
EN 868 specifies materials, test methods and values that are specific to the products covered by this
European Standard.
While materials specified in 4.2.2.1 to 4.2.2.3 of this part of EN 868 are intended for single use, the
materials specified in 4.2.2.4 are intended for reuse.

4 Requirements
4.1 General
For any material, preformed sterile barrier system or sterile barrier system, the requirements of
EN ISO 11607-1 shall 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.

A confirmation of compliance to EN 868-2 shall contain a statement whether EN ISO 11607-1 is
covered.
NOTE 2 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.
