The work of preparing International Standards is normally carried out thro
19、ugh ISO technical 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 collabor
20、ates closely with 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 Standa
21、rds. 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 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of t

ISO 10993-2 was prepared by Technical Committee ISO/TC 194, Biological evaluation of medical devices. This second edition cancels and replaces the first edition (ISO 109
23、93-2:1992), which has been technically revised.

28、ontext of the use of medical devices. This part of ISO 10993 supports the goal of the ISO 10993 series by promoting good science through paying proper regard to maximizing the use of scientifically sound non-animal tests and by ensuring that those animal tests performed to evaluate the biological pr
29、operties of materials used in medical devices are conducted humanely according to recognized ethical and scientific principles. The application of such humane experimental techniques, including high standards of animal care and accommodation, both help to ensure the scientific validity of safety tes
30、ting and enhance the welfare of the animals used. EN ISO 10993-2:20061Biological evaluation of medical devices Part 2: Animal welfare requirements 1 Scope This part of ISO 10993 is aimed at those who commission, design and perform tests or evaluate data from animal tests undertaken to assess the bio
31、compatibility of materials intended for use in medical devices, or that of the medical devices themselves. It specifies the minimum requirements to be satisfied to ensure and demonstrate that proper provision has been made for the welfare of animals used in animal tests to assess the biocompatibilit
32、y of materials used in medical devices. It also makes recommendations and offers guidance intended to facilitate future further reductions in the overall number of animals used, refinement of test methods to reduce or eliminate pain or distress in animals, and the replacement of animal tests by othe
33、r scientifically valid means not requiring animal tests. It applies to tests performed on living vertebrate animals, other than man, to establish the biocompatibility of materials or medical devices. It does not apply to tests performed on invertebrate animals and other lower forms; nor (other than
34、with respect to provisions relating to species, source, health status, and care and accommodation) does it apply to testing performed on isolated tissues and organs taken from vertebrate animals that have been euthanized. 2 Normative references The following referenced documents are indispensable fo

36、finitions For the purposes of this document, the definitions given in ISO 10993-1 and the following apply. 3.1 alternative method any test method that replaces an animal test, reduces the numbers of animals used, or refines the procedures applied 3.2 animal any live non-human vertebrate, excluding i
37、mmature forms during the first half of gestation of incubation EN ISO 10993-2:20062 3.3 animal test any use of an animal for scientific purposes NOTE 1 The definition of an animal test excludes acts of recognized veterinary practice applied for the benefit of an animal or the group of animals of whi
38、ch it is part; recognized husbandry practices to manage or conserve the animal or the group of which it is part; marking by methods which cause no more than momentary pain or distress; and euthanasia. NOTE 2 The prevention of pain, suffering, distress or lasting harm by the effective use of anaesthe
39、sia or analgesia or other methods of rendering the animal insentient to pain (e.g. decerebration) does not place animal tests outside the scope of this definition. The administration of anaesthetics, analgesics or other methods of rendering the animal insentient to pain are considered to constitute
40、an integral part of the animal test. 3.4 competent authority body designated or recognized by a national government to take responsibility for overseeing, supervising or regulating animal tests, or the breeding and supply of purpose-bred animals for use on such tests, within the scope of this part o

47、 3.14 validation formal process by which the reliability and relevance of a test method is established for a particular purpose 4 Requirements 4.1 General This part of ISO 10993 sets forth essential requirements when animal tests are being considered, planned or performed for the biological evaluati
48、on of materials used in medical devices. It has been developed to protect the welfare of animals used in the biological evaluation of materials used in medical devices without compromising, indeed to help to ensure, the scientific validity of the test results and the risk assessments that shall subs
49、equently be performed. This part of ISO 10993 focuses on the need to demonstrate that animal welfare is properly considered when expert judgement has to be exercised in relation to the biological evaluation of medical device materials, and that the principles of humane experimental technique are demonstrably applied to the design and conduct of animal tests. This part of ISO 10993 requires that the need to perform animal tests is justified, and any pain, suffering, distress or lasting harm that is caused during essential animal
