autoclaves and disinfectors, to subcommittee lbi/35/9, sterilization packaging materials, which has the responsibility to: aid enquirers to understand the text; present to the responsible european committee any enquiries on the interpretation, or proposals for change, and keep the uk interests informed; monitor related international and european developments and promulgate them in the uk.a list

in this document may be found in the bsi standards catalogue under the section entitled international standards correspondence index, or by using thefind facility of the bsi standards electronic catalogue.sterilization packaging materials falling within the scope of en 868-1 are considered to be medical devices under directive 93/42/eec and compliance with the requirements of en 868-1 is a means of ensuring that particular essential requirements of the directive are met (see annex za of en 868-1). this part ofen 868 may be used to demonstrate compliance with some of the requirements of part 1. however, compliance with this part of en 868 alone may not necessarily be considered to ensure that the essential requirements of the directive have been met.a british standard does not purport to include all the necessary provisions of a contract. users of british standards are responsible for their correct application.compliance with a british standard does not of itself confer immunity from legal obligations.summary of pagesthis document comprises a front cover, an inside front cover, the en title page, pages 2 to 9 and a back cover.the bsi copyright notice displayed in

test methods for all packaging materials and systems intended for use as packaging for medical devices which are to be terminally sterilized in their packaging.1 scopethis part of the series of en 868 provides examples of particular requirements and test methods for heat sealable adhesive coated paper manufactured from paper complying with en 868-6, for use as packagingof medical devices which are to be terminally sterilized with ethylene oxide or irradiation.it introduces no additional requirements to the general requirements of part 1 but provides guidance based upon various elements of former, relevant national standards.as such, the particular requirements in 4.2 to 4.6 can be used to demonstrate compliance with one or more but not all of the requirements of part 1.2 normative

particular requirements and test methods can be used to demonstrate compliance with one or more, but not all, of the requirements of en 868-1.4.2 materials4.2.1 raw materials used for the manufacture of packaging materials may be virgin or reclaimed materials provided that the source, history and traceability of all raw materials, especially recycled materials, are known and controlled to ensure that the finished product will consistently meet the requirements of this standard.note with current commercial technologies it is unlikely that reclaimed material other than manufacturing waste will be sufficiently controlled to allow its safe use for medical device packaging.4.2.2 the pulp shall be free from grit and untreated fragments of the original material from which the pulp was prepared.4.2.3 the adhesive coating shall not react with, contaminate, transfer to or adversely affect the product packed in it, before, during or after sterilization.4.3 conditioningwhere reference is made in the following performance requirements to conditioned wrap or to the need for conditioning prior to carrying out a test the wrap shall be conditioned in accordance with the method givenin en 20187.4.4 performance requirements and test methodsnote when the paper is to be used to manufacture packaging intended to be irradiation sterilized only, it is not necessary for it to have wet strength properties or any permeability to air,so 4.4.12, 4.4.13 and 4.4.17 need not apply.4.4.1 when examined by unaided normal or corrected vision in transmitted light (daylight or good artificial light) the paper shall be free from tears, creases or localized thickening sufficient to impair its functioning.4.4.2 no colour shall leach out of the wrap. compliance shall be tested by visual examination of a hot aqueous extract prepared in accordance with the method given in iso 65 note the paper can be printed.whether printed or not, no substance known to be toxic shall leach out of the paper or coating in sufficient quantity to cause a health hazard.until relevant european or international standards are published national regulations can apply.4.4.4 the average mass of 1 m2 of the conditioned coated paper when tested in accordance with iso 536 shall be within 7,5 % of the nominal value stated by the manufacturer.4.4.5 the ph of an aqueous extract of the coated paper shall be not less than 5 nor greater than 8 when tested in accordance with iso 6588, hot extraction method.4.4.6 the chloride content of the paper, calculated as sodium chloride, shall not exceed 0,05 % when tested in accordance with iso 9197-1, hot aqueous extraction.4.4.7 the sulphate content of the paper, calculated as sodium sulphate, shall not exceed 0,25 % when tested in accordance with iso 9198, hot aqueous extraction.4.4.8 the uncoated paper shall neither exhibit an increase in brightness due to the optical brightener of more than 1 % nor have more than five fluorescent spots each having an axis greater than 1 mmper 0,01 m2 when tested in accordance with 2.5of din 58953-6:19 the internal tearing resistance of the conditioned paper shall be not less than 300 mn in both machine and cross directions when tested in accordance with en 2190 the air permeance of the conditioned paper shall be not less than 0,2 mm/pas and not morethan 6,0 mm/pas when tested in accordance with iso 5636-1 the bursting strength of the conditioned paper shall be not less than 200 kpa when tested in accordance with iso 272 the wet bursting strength of the paper shall be not less than 35 kpa when tested in accordancewith iso 3689 using an immersion time of 10 min.4.4.13 the water repellency of the paper shall be such that the penetration time is not less than 20 s when tested in accordance with annex a.4.4.14 when tested in accordance with annex b, the average of the pore diameters of the ten test pieces shall be lower or equal to 20 mm. no value shall be greater than 30 mm.4.4.15 the coating shall be continuous and regular with no noncoated areas or discontinuity in the coating pattern which could provide gaps or channels in a seal when tested and examined in accordance withannex c.4.4.16 the tensile strength of the conditioned paper shall be not less than 4,0 kn/m in machine direction and not less than 2,0 kn/m in cross direction when tested in accordance with en iso 1924-7 the wet tensile strength of the paper shall be not less than 0,80 kn/m in machine direction and not less than 0,40 kn/m in cross directions when tested in accordance with iso 378
