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 sterilized medical devices“. The EN ISO 11607 series specifies general requirem
10、ents 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 standards organizations of the following countries are bound to implement this
11、European Standard: Austria, Belgium, 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 Un
12、ited Kingdom. EN 868-9:2009 (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 general requirements and test methods for materials, preformed sterile barrier systems, sterile
13、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 processes. Every sterile barrier system shall fulfil the requirements
14、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 21/2003 relating to the implementation of the uncertainty of measureme
15、nt 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 intention that the information required by CEN/BT 21/2003 be availa
16、ble 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 subject should be given priority during the next edition of the
17、 EN ISO 11607 series that is the basic reference for all parts of the EN 868 series. EN 868-9:2009 (E) 5 1 Scope This part of EN 868 provides test methods and values for uncoated nonwoven materials of polyolefines used for sterile barrier systems and/or packaging systems that are intended to maintai
18、n 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 par
19、t 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 not all of the requirements of EN ISO 11607-1. NOTE 2 When additional materials are used inside t
20、he 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 additional envelope around the medical device) then other requirements, including the determin
21、ation 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 referenced documents are indispensable for the application of this document.

NOTE EN ISO 11607-1:2006, 5.1.4 refers to conditions during production and handling with respect to their impact on the product (e.g. electrostat
27、ic conductivity, bioburden if applicable). 4.2 Materials The uncoated material shall be translucent or opaque and made of continuous filaments of polyolefines of a high level of purity and shall not release any substances in such quantities as could constitute a health risk. NOTE Attention is drawn
28、to EN ISO 10993-1. 4.3 Performance requirements and test methods 4.3.1 No colour shall leach out of the material. Compliance shall be tested by visual examination of a hot extract prepared in accordance with the method given in ISO 6588-2 modified to test temperature of (60 5) C. 4.3.2 The average m
29、ass of 1 m of the conditioned material when tested in accordance with EN ISO 536 shall be within 7 % of the nominal value stated by the manufacturer. 4.3.3 The tensile strength of the conditioned material shall be not less than 4,8 kN/m in the machine direction and not less than 5,0 kN/m in the cros
30、s direction when tested in accordance with EN ISO 1924-2. 4.3.4 The internal tearing resistance of the conditioned material shall be not less than 1 000 mN in both machine and cross directions when tested in accordance with EN 21974. 4.3.5 The delamination factor of the conditioned material shall be
31、 not less than 1 N/25,4 mm when tested in accordance with ASTM D 2724:1987. 4.3.6 The bursting strength of the conditioned material shall be not less than 575 kPa when tested in accordance with EN ISO 2758. 4.3.7 The air permeance of the conditioned material shall be not less than 1 km/Pa s at an ai
32、r pressure of 1,47 kPa when tested in accordance with ISO 5636-3. NOTE This requirement need not to apply to materials solely for use in irradiation sterilization packaging. 4.3.8 The resistance to water penetration of the conditioned material shall be determined using the hydrostatic head test base
33、d on EN 20811. This test method is currently under revision and considering other test conditions (use of support screen with an open area greater than 50 % in order to avoid early fabric rupture). Minimum requirements will be set as soon as the revised test method is available. Manufacturers may re
34、port test results. 4.4 Marking of the protective packaging The protective packaging shall be legibly and durably marked with the following information: a) reference, stock or catalogue number; b) quantity; c) the manufacturers or suppliers name or trade name, and address; EN 868-9:2009 (E) 7 d) date

37、nificant technical changes between this European Standard and the previous edition Changes between this European Standard and EN 868-9:2000 are the following: a) changes in order to align this European Standard with the EN ISO 11607 series, in particular by 1) amending the main element of the title,
38、 the scope and the terminology; 2) using EN ISO 11607-1 as normative reference regarding the general requirements for materials, sterile barrier systems and packaging systems; 3) deleting requirements that are covered by EN ISO 11607 (such as requirements on raw materials, conditioning, quality of t
39、he material with regard to tears, creases, localised thickening, leaching of toxic substances); b) in addition to a) first dash, the scope has been modified to 1) explain that other requirements might be of relevance for additional materials being used inside a sterile barrier system; 2) clarify tha
40、t the materials covered by this European Standard are intended for single use only; c) an explanatory note has been inserted to refer the user of this European Standard to the general requirements on conditions during production and handling with respect to their impact on the product in EN ISO 1160
41、7; d) requirements on tensile strength in machine direction and on bursting strength have been amended; e) requirement on the tolerance of the thickness of the material has been deleted; f) the requirement on resistance to water penetration has been formulated by taking into consideration that the a
42、pplicable test method in EN 20811 is currently under revision and that a value on resistance to water penetration can only be set on the basis of data received with this revised test method; g) requirements on marking have been amended; h) requirements on information to be provided by the manufactur
43、er have been added; i) informative annex on dimensions and tolerances has been deleted; j) text has been revised editorially (e.g. by updating normative and informative references).
