In addition, ISO/TC 198 “Sterilization of health care products“ in collaboration with CEN/TC 102 “Sterilizers for medical purposes“ has prepared the EN ISO 11607 series “Packaging for terminally
20、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). According to the CEN/CENELEC Internal Regulations, the national
21、standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Polan
22、d, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 868-10:2009EN 868-10:2009 (E) 4 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
23、 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 for
24、ming, 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 re
25、cognized 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
26、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 s
27、tandards. 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. BS EN 868-10:2009EN 868-10:2009 (E) 5 1 Scope This part of EN 868 provides test methods and values for sealable adhesi
28、ve coated nonwoven materials of polyolefines, manufactured from nonwovens complying with EN 868-9 used 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
29、 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 nor modify the general requirements specified in EN ISO 11607-1. As such, the particula
30、r requirements in 4.2 to 4.3 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, conta
31、iner 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 t
32、his part of EN 868 are intended for single use only. 2 Normative references The following referenced documents are indispensable for the application of this document.
