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.
