The work of preparing International Standards is normally carried out through ISO technical committees.
11、Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internat

In particular the different approval criteria needed for the differe
13、nt types of ISO documents should be noted.

17、ights reserved vISO 25841:2014(E)IntroductionA female condom is a sheath that completely lines the vaginal canal and is designated to be retained in the vagina during sexual intercourse and after withdrawal of the penis to prevent pregnancy and transmission of sexually transmitted infections (STIs).
18、A female condom is distinguished from a male condom in that it is retained in the vagina after withdrawal of the penis. The external component of the device can provide some coverage to the external female genitalia. Non-porous, intact, polymer films can be effective barriers to human immunodeficien
19、cy virus (HIV), to other infectious agents responsible for the transmission of STls, and to spermatozoa. Female condoms made from polymer films can be effective for contraceptive purposes and in the prevention of STI transmission. To be effective, it is essential that female condoms completely line
20、the vaginal canal, be free from holes and defects, have adequate physical properties so as not to break during use, are correctly packaged to protect them during storage, and are correctly labelled to facilitate their use.To be safe, it is essential that the female condom and any lubricant, additive
21、, dressing, individual packaging material, or powder applied to it neither contain nor liberate substances in amounts that are toxic, sensitizing, locally irritating, or otherwise harmful under normal conditions of storage or use.Female condoms are non-sterile medical devices, but manufacturers are
22、advised to take appropriate precautions to minimize microbiological contamination of the product during manufacturing and packaging. To ensure high quality products, it is essential that female condoms be designed and produced under a good quality management system. Reference can be made, for exampl
23、e, to ISO 9000, ISO 9001, ISO 9004, ISO 13485, and ISO 14971. To estimate the shelf-life of any new or modified female condom, manufacturers conduct stability tests before the product is placed on the market. This ensures that manufacturers have adequate data to support shelf-life claims and that th
24、ese data are available for review by regulatory authorities, test laboratories, and purchasers. They are also intended to limit the need for third parties to conduct long-term stability studies. Real-time shelf-life studies are also initiated, but not necessarily completed, prior to placing the prod
25、uct in the market.Because female condoms are a relatively new class of devices and designs of female condoms vary considerably, clinical investigations in humans are necessary to continue to build evidence of safety and efficacy. These investigations enable an assessment of the overall performance o
26、f internal and external retention features, failure modes, safety, and effectiveness of female condoms. This International Standard represents minimal requirements and test methods and acknowledges that new designs can require further due rigour of retention and other features as well as additional
27、definition of specifications and test methods by the manufacturer.All these issues are addressed in this International Standard.vi ISO 2014 All rights reservedFemale condoms Requirements and test methods1 ScopeThis International Standard specifies the minimum requirements and test methods for female

37、f individual female condoms contained in that package, and from which it is possible to trace those lots through all stages of manufacturing, packaging, and distributionNote 1 to entry: Whenever the consumer package contains only one kind of female condom, the identification number can be the same a
38、s the lot number. However, if the consumer package contains several different types of female condoms, for instance, female condoms of different shapes or colours, the identification number is different from the lot number.3.7individual containerprimary package containing a single female condom3.8in

40、ipment, and packed with the same lubricant and any other additive or dressing in the same type of individual containerNote 1 to entry: This International Standard does not specify the size of a lot; however, it is possible for a purchaser to do so as part of the purchasing contract. Attention is dra
41、wn to the difficulties that can be associated with the distribution and control of very large lots. The recommended maximum individual lot size for production is 500 000 female condoms.3.10lot numbernumber or combination of numerals, symbols, or letters used by the manufacturer to identify a lot of

Inevitably, there is some variation between individual female condoms. A small proportion
49、of female condoms in each production run might not meet the requirements in this International Standard. Furthermore, the majority of the test methods described in this International Standard is destructive. For these reasons, the only practicable method of assessing conformity with this International Standard is by testing a representative sample from a lot or series of lots. Basic sampling plans are identified in ISO 2859-1. See ISO/TR 8550 for guidance on the selection of an acceptance sampling system, scheme, or plan for the
