In addition, ISO/TC 198 “Sterilization of health care products” in collaboration with CEN/TC 102 “Sterilizers and associated equipment for pro

22、cessing of medical devices” 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 systems and packaging systems (Part 1) and validation requirements for forming, sealing and a

23、ssembly 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 Republ

BS EN 868-2:2017EN 868-2:2017 (E) 5 Introduction Th

25、e 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 i

26、ntended 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 se

27、ries 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

28、 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 868-2:2017EN 868-2:2017 (E) 6 1 Scope This European Standard specifies test methods and values for materials for sterile barrier systems and/or packaging systems that are intend

29、ed 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 Sta

30、ndard. 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable

This part of EN 868 only introduces perform

40、ance 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.

41、equirements of EN ISO 11607-1. NOTE 1 Compliance to EN 8682 does not automatically mean compliance to 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 o

42、rder 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
