15、word This document (EN 868-2:2009) has been prepared by Technical Committee CEN/TC 102 “Sterilizers for medical purposes”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, a
16、t the latest by November 2009, and conflicting national standards shall be withdrawn at the latest by November 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying
17、any or all such patent rights. This document supersedes EN 868-2:1999. Annex A provides details of significant technical changes between this European Standard and the previous edition.

In additio
21、n, ISO/TC 198 “Sterilization of health care products“ in collaboration with CEN/TC 102 “Sterilizers for medical purposes“ has prepared the series EN ISO 11607 “Packaging for terminally sterilized medical devices“. The EN ISO 11607 series specifies general requirements for materials, sterile barrier
22、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 organizations of the following countries are bound to implement this European Standard: Austria, Belgium,
23、 Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

25、zed 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
26、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 th
27、e 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
28、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
29、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.

30、 under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS EN 868-2:2009EN 868-2:2009 (E) 5 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
31、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
32、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 steril
33、e 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
34、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 t
35、he material for sterile barrier system specifies the use as sterile field, then the additional requirements of the EN 13795 series apply. 2 Normative references The following referenced documents are indispensable for the application of this document.
