21、ackaging 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 Internal R
22、egulations, the national 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

BS EN 868-4:2017EN 868-4:2017 (E) 4 Introduction The EN ISO 11607 series consists of two parts under the general title
24、 “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 maintain sterility of terminally sterilized medical devic
25、es to the point of 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 and EN ISO 11607-2. The EN 868 series can be used to demonstrate compliance with o
26、ne or more of the requirements specified 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 seri
27、es that is the basic reference for all parts of the EN 868 series. BS EN 868-4:2017EN 868-4:2017 (E) 5 1 Scope This European Standard specifies test methods and values for paper bags manufactured from paper specified in EN 868-3, used as sterile barrier systems and/or packaging systems that are inte
28、nded 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 to the products covered by this European S
29、tandard. 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.

35、1 General For any preformed sterile barrier system or sterile barrier system, the requirements of EN ISO 11607-1 and EN ISO 11607-2 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
36、 add or modify the general requirements specified in EN ISO 11607-1. As such, the particular requirements in 4.5 can be used to demonstrate compliance with one or more but not all of the requirements of EN ISO 11607-1. NOTE 1 Compliance to EN 8684 does not automatically mean compliance to EN ISO 116
37、07-1. A confirmation of compliance to EN 868-4 shall contain a statement whether EN ISO 11607-1 and EN ISO 11607-2 are covered. 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 fi
38、lter, 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 validation activities, can apply. 4.2 Construction and design 4.2.1 G
39、eneral 4.2.1.1 The bags shall be manufactured from single web paper specified in EN 868-3. 4.2.1.2 The following terms shall be used to describe the design of the bag: a) back the surface of the bag with a longitudinal seam; b) front the surface of the bag with no longitudinal seam; c) unlipped wher
40、e the length of both the front and back surfaces are the same and the front surface has a thumb cut (9 3) mm deep and not less than 15 mm wide; d) lipped where the length of the back surface is greater than the length of the front surface by not less than 10 mm and not more than 25 mm; e) gusseted w
41、here the construction of the bag includes side panels; f) ungusseted where the longitudinal edges of the front and back surfaces are contiguous; g) seal top where there is a continuous strip of seal adhesive on the inner surface of the front, back and gussets (if gusseted) of the top of the bag; h)
42、plain top where there is no seal adhesive. 4.2.1.3 The adhesive(s) used in the construction of the bag shall be water resistant and non-corrosive, subsequently referred to as “construction adhesive(s)”. BS EN 868-4:2017EN 868-4:2017 (E) 7 4.2.2 Bottom seal formation The bottom seal shall be formed b
43、y using one of the following methods: a) the bottom shall be double folded with each fold bonded with “construction adhesive”, or b) the bottom shall be sealed across the entire width with a “construction adhesive” or with a seal not less than 6,5 mm in depth, or c) the bottom shall be sealed across
44、 the entire width as described in b) and then folded once, or more, each fold being bonded with (a) construction adhesive(s) or with a heat seal. 4.2.3 Back seam construction 4.2.3.1 The longitudinal seam shall be made at the back of the bag with a continuous double line of “construction adhesive(s)
45、”. 4.2.3.2 A coloured adhesive shall be used to enable a simple visual check on the continuity of both glue lines. 4.2.3.3 The dye shall not impair the adhesive. 4.3 Process indicator If one or more Type I indicator(s) (process indicator(s) are printed on the pouches and tubes, the indicators perfor
46、mance shall comply with the requirements of EN ISO 11140-1. Each individual indicator shall be not less than 100 mm2in area. Indicators shall not be affected by the sealing procedure. 4.4 Seal strip 4.4.1 For bags with a seal closure the seal adhesive shall be applied as a continuous strip to the in
47、ner surface of the front, back and (if gusseted) the gussets of the bag. 4.4.2 The width of the seal strip shall be (25 3) mm for bags with a width not exceeding 200 mm and (40 3) mm for bags with a width exceeding 200 mm. 4.4.3 The top edge of the seal strip shall be positioned not less than 2 mm a
48、nd not more than 10 mm from the lower lip or bottom of the thumb cut. 4.5 Performance requirements and test methods NOTE See Annex D for repeatability and reproducibility of the test methods: sulphate content and chloride content. For information on statement of precision and/or bias, repeatability
49、and reproducibility of other test methods, see EN ISO 11607-1:2009+A1:2014, Table B.1. 4.5.1 The pH of the aqueous extract of the paper and adhesive sandwich shall be within the range 4,5 to 8,0 when tested in accordance with Annex B. 4.5.2 The chloride content of the aqueous extract of the paper and adhesive sandwich, calculated as sodium chloride, shall not exceed 0,05 % when tested in accordance with Annex B. 4.5.3 The sulphate content of the aqueous extract of the paper and adhesive sandwich, calcu
