21、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 terminally sterilized medical devices”. The EN
22、 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 national standards organisations of the fol
23、lowing 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, Lithuania, Luxembourg, Malta, Netherlands,

BS EN 868-6:2017EN 868-6:2017 (E) 4 Introduction The EN ISO 11607 series consists of two parts under the general title “Packaging for terminally sterilized medical devices”. Par
25、t 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 specifies val
26、idation 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 specified in EN ISO 11607-1. CEN/TC 102/WG 4 al
27、so 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 of the EN 868 series. BS EN 868-6
28、:2017EN 868-6:2017 (E) 5 1 Scope This European Standard specifies test methods and values for paper used in the manufacture of preformed sterile barrier systems and/or packaging systems that are intended to maintain sterility of terminally sterilized medical devices to the point of use. Other than t
29、he 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 to the products covered by this European Standard. Paper specified in this European Standard is intended for use in part or complete manufactur
30、e of pouches and form and fill packs and lidding material for trays. NOTE 1 The paper specified in this part of the EN 868 series is suitable for the manufacture of sterile barrier systems to be used in ethylene oxide, irradiation or low temperature steam formaldehyde sterilization processes and to
31、produce coated paper according to EN 8687. NOTE 2 Paper according to EN 8683 can also be used for these sterilization processes. 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 refer
32、enced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 20187, Paper, board and pulps - Standard atmosphere for conditioning an

39、 shall apply. 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 or modify the general requirements specified in EN ISO 11607-1. As such, the particular requirements in 4.2 can be used to dem
40、onstrate compliance with one or more but not all of the requirements of EN ISO 11607-1. NOTE 1 Compliance to EN 8686 does not automatically mean compliance to EN ISO 11607-1. A confirmation of compliance to EN 868-6 shall contain a statement whether EN ISO 11607-1 is covered. NOTE 2 When additional
41、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 additional envelope around the medical device) then other requireme
42、nts, including the determination of the acceptability of these materials during 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 rep
43、ellency. For information on statement of precision and/or bias, repeatability and reproducibility of other test methods, see EN ISO 11607-1:2009+A1:2014, Table B.1. 4.2.1 When the paper is to be used to manufacture packaging intended to be irradiation sterilized only, it is not necessary for it to h
44、ave wet strength properties or any permeability to air, so 4.2.11, 4.2.12 and 4.2.15 need not apply. 4.2.2 No colour shall leach out of the paper. Compliance shall be tested by visual examination of a hot aqueous extract prepared in accordance with the method given in ISO 6588-2. 4.2.3 The average m
45、ass of 1 m2of the conditioned paper when tested in accordance with EN ISO 536 shall be within 5 % of the nominal value stated by the manufacturer. BS EN 868-6:2017EN 868-6:2017 (E) 7 4.2.4 The pH of an aqueous extract of the paper shall be not less than 5 nor greater than 8 when tested in accordance
46、 with ISO 6588-2, hot extraction method. 4.2.5 The chloride content of the paper, calculated as sodium chloride, shall not exceed 0,05 % when tested in accordance with ISO 9197 using a hot extract prepared in accordance with ISO 6588-2:2012, 7.2 except that 2 ml of potassium chloride solution is not
47、 added. 4.2.6 The sulphate content of the paper, calculated as sodium sulphate, shall not exceed 0,25 % when tested in accordance with ISO 9198, using a hot extract prepared in accordance with ISO 6588-2:2012, 7.2 except that 2 ml of potassium chloride solution is not added. 4.2.7 When tested in acc
48、ordance 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 measured with the 420 nm UV-cut-off filter in place to the D65 brightness measured without 420 nm UV-cut-off fil
49、ter. 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.
