The EN ISO 11607 series specifies general requirements for materials, sterile barrier systems and packaging systems (Part 1) and
5、 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 European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark
6、, 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 United Kingdom. BS EN 868-5:2009EN 868-5:2009 (E) 4 Introduction The EN ISO 1160
7、7 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 intended to mai
8、ntain 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 of EN ISO 11607-1. The EN 868 series can be used to demonstrat
9、e 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 measurement concept in standards. Following this Resolution and the cor
10、responding 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 available for inclusion in EN 868 parts 2 to 10 during one of their
11、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 EN ISO 11607 series that is the basic reference for all parts
12、 of the series EN 868. BS EN 868-5:2009EN 868-5:2009 (E) 5 1 Scope This part of EN 868 provides test methods and values for sealable pouches and reels manufactured from porous materials complying with either EN 868 part 2, 3, 6, 7, 9 or 10 and plastic film complying with Clause 4 used as sterile bar
13、rier 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 may be determined by the manufacturer and the user. This part of EN 868 only introduces performance requirements and
14、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 4.5 can be used to demonstrate compliance with one or more but not all of the requirements of
15、EN ISO 11607-1. The materials specified in this part of EN 868 are intended for single use only. 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
16、, 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. 2 Normative references The following referenced documents are indi

23、607-1:2006 and the following apply. 3.1 healthcare facility location where patients are medically treated and/or medical devices are terminally sterilized EXAMPLE Hospital, dentist office, practitioner. 4 Requirements 4.1 General The requirements of EN ISO 11607-1 apply. NOTE 1 EN ISO 11607-1:2006,
24、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 2 For validation requirements for forming, sealing and assembly processes, see EN ISO 11607-2. 4.2 Materials 4.2.1 Porous material Th
25、e porous material shall comply with the requirements of either EN 868 part 2, 3, 6, 7, 9 or 10. When the porous material is to be used to manufacture preformed sterile barrier systems intended to be irradiation sterilized only, requirements for wet strength properties or permeability to air need not
26、 apply. 4.2.2 Plastic film 4.2.2.1 The plastic film shall be a composite of two or more layers. When tested after the intended sterilization process in accordance with Annex B the plastics interply bond shall not separate nor become cloudy. 4.2.2.2 The plastic film shall be free from pinholes when t
27、ested in accordance with Annex C. 4.2.2.3 When examined by unaided normal or corrected vision in transmitted light (daylight or good artificial light) the plastic film shall be free from foreign matter and/or other imperfections that would adversely affect compliance with the requirements of 4.5. NO
28、TE Slight continuous surface irregularities arising from the extrusion of the plastic film is not regarded as a defect. 4.2.2.4 The plastic film shall be sealable to the porous material under the conditions specified by the manufacturer (see Clause 5, NOTE 1). 4.2.2.5 The breaking factor of the plas
29、tics film shall be not less than 20 N per 15 mm width when tested in accordance with ASTM D 882:1995 (Method A).

30、along parallel sides. Pouches shall be constructed from one layer of porous material and one layer of plastic film by sealing three sides and may include an area to effect closure of the pouch. 4.3.2 The overall width of the seal(s) shall be not less than 6 mm. For ribbed seals, the sum of the width
31、s of the ribs shall be not less than 6 mm. 4.3.3 The distance between the end of a pouch and the nearest edge of the width wise seal shall be sufficient to enable the two webs to be separated and peeled apart. NOTE The side seals can extend beyond the width wise seal to the end of the pouch provided
32、 that this does not impair peelability. 4.3.4 One of the materials of a pouch shall: a) be provided with a thumb notch not more than 12 mm deep at either the top or bottom of the pouch or at both ends. The bottom of the notch shall be at least 1 mm from the seal; or b) be lipped such that the length
33、 of one web is greater than the length of the other web by not less than 1,0 mm. 4.3.5 The pouch and/or reel shall be closed according to the manufacturers instructions. NOTE 1 For validation requirements for forming, sealing and assembly processes, see EN ISO 11607-2. NOTE 2 The closure and or seal
34、ing system may give the possibility to indicate whether or not the seal has been opened. 4.4 Process indicator If one or more Class I indicator(s) (process indicator(s) are printed on the pouches and tubes, the indicators performance shall comply with the requirements of EN ISO 11140-1. Each individ
