In addition, ISO/TC 198 “Sterilization of health care products“ in collaboration with CEN/TC 102

23、 “Sterilizers for medical purposes“ has prepared the EN ISO 11607 series “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, sealin

24、g 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, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece,

Part 1 of this series specifies general requirements and test me

27、thods 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 proces

28、ses. 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 21/200

29、3 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 int

30、ention 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

31、 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.

32、cense from IHS-,-,-BS EN 868-7:2009EN 868-7:2009 (E) 5 1 Scope This part of EN 868 provides test methods and values for sealable adhesive coated paper manufactured from paper complying with EN 868-6, used as sterile barrier systems and/or packaging systems that are intended to maintain sterility of

33、terminally sterilized medical devices to the point of use. The materials specified in this part are intended to be used for ethylene oxide or irradiation sterilization. NOTE 1 The need for a protective packaging may be determined by the manufacturer and the user. This part of EN 868 only introduces

34、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 to 4.3 can be used to demonstrate compliance with one or more but no

35、t 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

36、 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 this part of EN 868 are intended for single use only. 2 Normative references The following

NOTE EN ISO 11607-1:2006, 5.1.4 refers to conditions d

44、uring production and handling with respect to their impact on the product (e.g. electrostatic conductivity, bioburden if applicable). 4.2 Materials The adhesive coating shall not react with, contaminate, transfer to or adversely affect the product packed in it, before, during or after sterilization.

45、 4.3 Performance requirements and test methods 4.3.1 When the paper is to be used to manufacture packaging intended to be irradiation sterilized only, it is not necessary for it to have wet strength properties or any permeability to air, so 4.3.11 and 4.3.16 need not apply. 4.3.2 No colour shall lea
