This European Standard shall be
17、given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2017, and conflicting national standards shall be withdrawn at the latest by August 2017. Attention is drawn to the possibility that some of the elements of this document ma
18、y be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 868-3:2009. Annex A provides details of significant technical changes between this European Standard and the previous edition. EN 868 consists of the follow
19、ing parts, under the general title Packaging for terminally sterilized medical devices: Part 2: Sterilization wrap Requirements and test methods; Part 3: Paper for use in the manufacture of paper bags (specified in EN 868-4) and in the manufacture of pouches and reels (specified in EN 868-5) Require
20、ments and test methods; Part 4: Paper bags Requirements and test methods; Part 5: Sealable pouches and reels of porous materials and plastic film construction Requirements and test methods; Part 6: Paper for low temperature sterilization processes Requirements and test methods; Part 7: Adhesive coat
21、ed paper for low temperature sterilization processes Requirements and test methods; Part 8: Re-usable sterilization containers for steam sterilizers conforming to EN 285 Requirements and test methods; Part 9: Uncoated nonwoven materials of polyolefines Requirements and test methods; Part 10: Adhesiv
22、e coated nonwoven materials of polyolefines Requirements and test methods. In addition, ISO/TC 198 “Sterilization of health care products” in collaboration with CEN/TC 102 “Sterilizers and associated equipment for processing of medical devices” has prepared the EN ISO 11607 series “Packaging for ter
23、minally 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 Internal Regulations, the n
24、ational 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 Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
25、Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 868-3:2017EN 868-3:2017 (E) 4 Introduction The EN ISO 11607 series consists of two parts under the general title “Packaging for t
26、erminally 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 maintain sterility of terminally sterilized medical devices to the point o
27、f 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 series can be used to demonstrate compliance with one or more of the requirements speci
28、fied 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 during the next edition of the EN ISO 11607 series that is the basic reference for a
29、ll parts of the EN 868 series. BS EN 868-3:2017EN 868-3:2017 (E) 5 1 Scope This European Standard specifies test methods and values for paper, used in the manufacture of paper bags (specified in EN 868-4) and in the manufacture of pouches and reels (specified in EN 868-5) used as sterile barrier sys
30、tems and/or packaging systems that are intended 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
31、 to the products covered by this European Standard. The materials specified in this part of EN 868 are intended for single use only. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

38、his document, the terms and definitions given in EN ISO 11607-1:2009+A1:2014 apply. 4 Requirements 4.1 General For any material, preformed sterile barrier system or sterile barrier system, the requirements of EN ISO 11607-1 shall apply. This part of EN 868 only introduces performance requirements an
39、d 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 can be used to demonstrate compliance with one or more but not all of the requirements of EN IS
40、O 11607-1. NOTE 1 Compliance to EN 8683 does not automatically mean compliance to EN ISO 11607-1. A confirmation of compliance to EN 868-3 shall contain a statement whether EN ISO 11607-1 is covered. NOTE 2 When additional materials are used inside the sterile barrier system in order to ease the org
41、anization, 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 duri
42、ng validation activities, can apply. 4.2 Performance requirements and test methods NOTE See Annex D for repeatability and reproducibility of the test methods: pore diameters, sulphate content, chloride content and water repellency.

47、 ISO 6588-2:2012, 7.2 except that 2 ml of potassium chloride solution is not added. 4.2.7 When tested in accordance with ISO 2470-2 the material shall not exhibit an increase in D65 brightness, due to the optical brightener agents, of more than 1 %; calculated as the ratio of the D65 brightness meas
48、ured with the 420 nm UV-cut-off filter in place to the D65 brightness measured without 420 nm UV-cut-off filter. 4.2.8 When exposed at 25 cm from a UV light source, the material shall not have per 0,01 m2more than five fluorescent spots, each having an axis greater than 1 mm. NOTE The UV light to be
49、 used is the one described as per Annex B. 4.2.9 The internal tearing resistance of the conditioned paper shall be not less than 550 mN in both machine and cross direction when tested in accordance with EN ISO 1974. 4.2.10 The air permeance of the conditioned paper shall be not less than 3,4 m/Pa s at an air pressure of 1,47 kPa when tested in accordance with ISO 5636-3. 4.2.11 The bursting strength of the conditioned paper shall be not less than 230 kPa when tested in accordance with EN ISO 2758. 4.2
