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 s
26、eries “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 assembly processes (Part 2). According to the CEN/CENELEC Int
27、ernal 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, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, M

DIN EN 868-8:2009-09 EN 868-8:2009 (E) 4 Introduction The EN ISO 11607 series consists of two parts under the general title “Packaging for terminally sterilized medical device
29、s“. 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 specif
30、ies 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 8
31、68 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
32、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
33、 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. DIN EN 868-8:2009-09 EN 868-8:2009 (E) 5 1 Scope This part of EN 868 provides test
34、methods and values for re-usable containers used as sterile barrier systems that are intended to maintain sterility of terminally sterilized medical devices to the point of use. These containers are intended to be used in steam sterilizers conforming to EN 285. NOTE 1 The need for a packaging materi
35、al inside the container is determined by the manufactures and users. 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 suc
36、h, the particular requirements in 4.2 to 4.5 can be used to demonstrate compliance with one or more but not all of the requirements of EN ISO 11607-1. NOTE 2 When it is intended to use the containers in a steam sterilizer not conforming to EN 285 the sterilization per-formance of the container in th
37、e specific sterilization cycle to be used is validated by the user. Other attributes of the container are also reviewed for compatibility with the sterilizer cycle e.g. operating temperature. NOTE 3 When additional materials are used inside the sterile barrier system in order to ease the organizatio
38、n, 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 these materials during valid
39、ation activities, may apply. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

NOTE 1 EN ISO 11607-1, 5.1.10 specifies additional requirements for reusable containers. DIN EN 868-8:2009-09 EN 868-8:2009 (E) 6 NOTE 2 EN ISO 11607-
43、1:2006, 5.1.4 refers to conditions during production and handling with respect to their impact on the product (e.g. electrostatic conductivity, bioburden if applicable). NOTE 3 For validation requirements for forming, sealing and assembly processes, see EN ISO 11607-2. 4.2 Requirements for construct
44、ion and design 4.2.1 Shape and dimension 4.2.1.1 The container shall be in the general form of a parallelepipedal box. NOTE Slight curvature or camber of the flat surfaces can be acceptable. Rounding of the corners is desirable. 4.2.1.2 The container including all connected parts e.g. handles shall
45、fit within one sterilization module (see EN 285). NOTE 1 If the container does not fit within one sterilization module, but complies with all other requirements of this part of the standard, the manufacturer can claim compliance with EN ISO 11607-1, but not with EN 868-8. NOTE 2 For guidance on dime
