EN 868 consists of the following parts, under the general title Packaging for terminally sterilized medical devices: Part 2: Sterilization wrap Requirements and

17、 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) Requirements and test methods; Part 4: Paper bags Requirements and test methods; Part 5: Sealable pouches and reels of porous materials an

In addition, ISO/TC 198 “Sterilization of health care pr

20、oducts“ 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 requirements for materials, sterile barrier systems and packaging systems (Part 1) and val

21、idation 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, Es

22、tonia, 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 868-8:2009EN 868-8:2009 (E) 4 Introduction The EN ISO 11607 se

23、ries 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 maintai

24、n 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 demonstrate co

25、mpliance 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 corresp

26、onding 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 next

27、 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 of

28、the EN 868 series. BS EN 868-8:2009EN 868-8:2009 (E) 5 1 Scope This part of EN 868 provides test methods and values for re-usable containers used as sterile barrier systems that are intended to maintain sterility of terminally sterilized medical devices to the point of use. These containers are inte

29、nded to be used in steam sterilizers conforming to EN 285. NOTE 1 The need for a packaging material inside the container is determined by the manufactures and users. This part of EN 868 only introduces performance requirements and test methods that are specific to the products covered by this part o

30、f EN 868 but does not add nor 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 EN ISO 11607-1. NOTE 2 When it is intended to use the containers in

31、a steam sterilizer not conforming to EN 285 the sterilization per-formance of the container in the specific sterilization cycle to be used is validated by the user. Other attributes of the container are also reviewed for compatibility with the sterilizer cycle e.g. operating temperature. NOTE 3 When

32、 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, mats, instrument organizer sets, tray liners or an additional envelope around the medical device) then oth

33、er requirements, including the determination of the acceptability of these materials during validation activities, may apply. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For un

NOTE 1 EN ISO 11607-1, 5.1.10 specifies additional re

37、quirements for reusable containers. BS EN 868-8:2009EN 868-8:2009 (E) 6 NOTE 2 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. electrostatic conductivity, bioburden if applicable). NOTE 3 For validation requirements for

NOTE Slight curvature or camber of the flat surfaces can be acceptable. Rounding of the c

39、orners is desirable. 4.2.1.2 The container including all connected parts e.g. handles shall fit within one sterilization module (see EN 285). NOTE 1 If the container does not fit within one sterilization module, but complies with all other requirements of this part of the standard, the manufacturer

40、can claim compliance with EN ISO 11607-1, but not with EN 868-8. NOTE 2 For guidance on dimensions see informative Annex B. 4.2.1.3 For ease of cleaning all internal corners shall be radiused. 4.2.2 Lids and lid-latching devices 4.2.2.1 Access to the interior of the container shall be provided by a

41、lid. 4.2.2.2 The lid shall be secured to the base during use by locking devices. The closure shall comply with the requirements in EN ISO 11607-1:2006, 5.1.10 c). 4.2.3 Tamper evident closure system 4.2.3.1 A tamper evident closure system complying with EN ISO 11607-1:2006, 5.1.10 a) shall be availa

42、ble. 4.2.3.2 If the tamper evident closure system is not a single-use disposable item, i.e. does not irrevocably break when opened, then a special tool, key, code or treatment shall be required to re-set the closure system. 4.2.4 Gasket 4.2.4.1 The interface between the lid and base shall be provide

43、d with a closure gasket. The closure formed by the gasket with the lid latched in position shall provide microbial barrier properties as specified in EN ISO 11607-1:2006, 5.2 and 5.1.10 c). 4.2.4.2 The gasket shall be accessible for cleaning. Frequency and method of maintenance shall be specified by

46、ability 4.2.6.1 The top and base of each container shall be sufficiently strong to allow stacking and shall be fitted with means to ensure that all containers of the same nominal size and of the same provenance shall stack securely. After the test in accordance with Annex D, the container shall show

47、 no permanent deformation 1 mm and shall have unchanged performance characteristics. When tested in accordance with Annex E, the tested container shall remain stacked. 4.2.6.2 The containers shall be designed and constructed so that when stacked and loaded into the sterilizer in the manner specified

48、 by the manufacturer they will allow free passage of steam and/or air between containers. Compliance shall be tested by the performance tests carried out as described in Annex C to F. 4.2.7 Sterilant Port 4.2.7.1 Each container shall be provided with a sterilant port in one or more of its principle

49、surfaces. 4.2.7.2 The sterilant port shall be designed to meet the following requirements: a) It shall permit the attainment of the specified sterilization conditions. Compliance shall be tested in accordance with Annex F. b) It shall permit adequate drying when processed in a sterilizer conforming to EN 285.
