36、d the essential principles of ISO/TR 16142 . 81 EN ISO 22523:2006vi Foreword ISO (the International Organization 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 technica
37、l committees. 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 wit
38、h the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Inter
39、national 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 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may
40、 be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22523 was prepared by Technical Committee ISO/TC 168, Prosthetics and orthotics. EN ISO 22523:2006viiIntroduction This International Standard has been prepared in close collaboratio
41、n with Technical Committee CEN/TC 293 Technical aids for disabled persons. This International Standard represents the revised version of the Harmonized European Standard EN 12523:1999 already implemented by the member countries of the European Union and the European Free Trade Association in accorda
42、nce with the CEN/CENELEC Internal Regulations. Consequently, these regulations apply accordingly. This International Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For
43、 relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this International Standard. This International Standard provides one means to demonstrate that external limb prostheses and external orthoses, which are also medical devices, conform to the essential requirem
44、ents outlined in general terms in Annex 1 of the EU Directive 93/42/EEC on medical devices. This International Standard also provides means to demonstrate that external limb prostheses and external orthoses with radio equipment according to definition 3.8 conform to the essential requirements of the
45、 EU Directive 99/5/EC on radio equipment and telecommunications terminal equipment. This standard is not intended to provide a means of showing conformity with the requirements of any other directive. There are three levels of European Standard dealing with technical aids for disabled persons. These
46、 are as follows, with level 1 being the highest: Level 1: General requirements for technical aids Level 2: Particular requirements for families of technical aids Level 3: Specific requirements for types of technical aids. Where standards for particular aids or groups of aids exist (level 2 or 3), th
47、e requirements of lower-level standards take precedence over higher-level standards. Therefore, to address all requirements for a particular aid, it is necessary to consult first, standards of the lowest available level. This is a combined level 2- and 3-standard (lowest possible) for external limb
48、prostheses and external orthoses, as specified in the scope. In this International Standard, in addition to the reference to existing test standards, test methods for several types of prostheses and orthoses are specified in separate annexes A to D. Annex ZA is included to show the parts of this Eur
49、opean Standard which address the essential requirements of EU Directives 93/42/EEC and 99/5/EC. NOTE Although this International Standard does not contain references to the level 1-standard EN 12182 Technical aids for disabled persons General requirements and test methods, it is recommended that EN 12182 be consulted.
