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 shall 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.
During the revision of EN 868 parts 2 to 10, CEN/TC 102/WG 4 recognized Resolution CEN/BT 21/2003
relating to the implementation of the uncertainty of measurement concept in standards. Following this
Resolution and the corresponding guidance, CEN/TC 102/WG 4 has initiated a review of the test methods
needed to show compliance with the requirements specified in EN 868 parts 2 to 10 with the intention that the
information required by CEN/BT 21/2003 be available for inclusion in EN 868 parts 2 to 10 during one of their
next revisions.
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 part of EN 868 provides 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.
NOTE 1 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.
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, may apply.
The 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.
NOTE 3 If the intended purpose according to the manufacturer of the material for sterile barrier system specifies the
use as sterile field, then the additional requirements of the EN 13795 series apply.
