13、ganization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establ
14、ished 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 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizati
15、on. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 %
16、of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 7439 was prepared by th
17、e European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 157, Mechanical contraceptives, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this document, read “.this European Standard.“ to m
18、ean “.this International Standard.“. This second edition cancels and replaces the first edition of ISO/TR 7439 (ISO/TR 7439:1981), which has been technically revised. Annex ZZ forms a normative part of this International Standard. Annex ZZ provides a list of corresponding International and European

23、n the status of a national standard, either by publication of an identical text orby endorsement, at the latest by September 2002, and conflicting national standards shall be withdrawn at thelatest by September 2002.This European Standard needs to be considered in conjunction with EN ISO 14630, whic
24、h contains requirements thatapply to all non-active surgical implants. Although contraceptive intra-uterine devices are not surgical implants, most ofthe requirements of EN ISO 14630 may be applicable to contraceptive intra-uterine devices.This document has been prepared under a mandate given to CEN
25、 by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard : Austria, Belgiu

27、ABS .ISO 7439:2002(E) vi ISO 2002 All rights reservedIntroduction Although every foreign object in the uterus exhibits a certain contraceptive effect, the method by which copper-bearingintra-uterine contraceptive devices (IUDs) function is by the continuous release of copper ions. This interferes wi
28、thsome enzymatic functions, immobilizes sperm cells and inhibits fertilization. In addition, growth and development ofthe ovum, tubal function and implantation are inhibited and the biochemical environment of the uterus is altered. Thesecontribute to the high effectiveness of contraception.The effec
29、tiveness of copper-bearing contraceptive intra-uterine devices is many times greater than that of a simpleplastics body.Contraceptive intra-uterine devices containing copper are regarded as medical devices incorporating a substance withan ancillary action and are subject to Council Directive 93/42/E
30、EC of 14 June 1993 concerning medical devices.Contraceptive intra-uterine devices whose primary purpose is to release progestogens are regulated as medicinalproducts and are subject to Council Directive 65/65/EEC of 26 January 1965 on the approximation of provisions laiddown by law, regulation or ad
31、ministrative action relating to proprietary medicinal products. The relevant essentialrequirements of Annex I to Directive 93/42/EEC apply as far as safety and performance-related device features areconcerned.SANS 7439:2009This s tandard may only be used and printed by approved subscription and free
