© ISOISO 10993-5:1999(E)iiiForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.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 % of the member bodies casting a vote.International Standard ISO 10993-5 was prepared by Technical Committee ISO/TC 194, Biological evaluation ofmedical devices.This second edition cancels and replaces the first edition (ISO 10993-5:1992), which has been technically revised.ISO 10993 consists of the following parts, under the general title Biological evaluation of medical devices:¾ Part 1: Evaluation and testing¾ Part 2: Animal welfare requirements¾ Part 3: Tests for genotoxicity, carcinogenicity and reproductive toxicity¾ Part 4: Selection of tests for interactions with blood¾ Part 5: Tests for in vitro cytotoxicity¾ Part 6: Tests for local effects after implantation¾ Part 7: Ethylene oxide sterilization residuals¾ Part 8: Guidance for reference materials¾ Part 9: Framework for the identification and quantification of potential degradation products¾ Part 10: Tests for irritation and sensitization¾ Part 11: Tests for systemic toxicity¾ Part 12: Sample preparation and reference materials¾ Part 13: Identification and quantification of degradation products from polymers¾ Part 14: Identification and quantification of degradation products from ceramics¾ Part 15: Identification and quantification of degradation products from metals and alloys¾ Part 16: Toxicokinetic study design for degradation products and leachables¾ Part 17: Methods for establishment of allowable limits for leachable substances using health-based riskassessment¾ Part 18: Chemical characterizationFuture parts will deal with other relevant aspects of biological testing.kSIST prEN ISO 10993-5:2009
ISO 10993-5:1999(E)© ISOivIntroductionDue to the general applicability of in vitro cytotoxicity tests and their widespread use in evaluating a large range ofmedical devices and materials, it is the purpose of this part of ISO 10993, rather than to specify a single test, todefine a scheme for testing which requires decisions to be made in a series of steps. This should lead to theselection of the most appropriate test.Three categories of test are listed: extract test, direct-contact test, indirect-contact test.The choice of one or more of these categories depends upon the nature of the sample to be evaluated, the potentialsite of use and the nature of the use.This choice then determines the details of the preparation of the samples to be tested, the preparation of thecultured cells, and the way in which the cells are exposed to the samples or their extracts.At the end of the exposure time, the evaluation of the presence and extent of the cytotoxic effect is undertaken. It isthe intention of this part of ISO 10993 to leave open the choice of type of evaluation. Such a strategy makesavailable a battery of tests, which reflects the approach of many groups which advocate in vitro biological tests.The numerous methods used and end-points measured in cytotoxicity determination can be grouped into categoriesof evaluation type:a) assessments of cell damage by morphological means;b) measurements of cell damage;c) measurements of cell growth;d) measurements of specific aspects of cellular metabolism.There are, therefore, several alternative means of producing results in each of these four categories. Theinvestigator should be aware of the categories of test and into which a particular technique fits, in order thatcomparisons may be made with other results on similar medical devices or materials, and in order thatinterlaboratory tests may be conducted.kSIST prEN ISO 10993-5:2009

For example, high-density poly-ethylene1) for synthetic polymers, and aluminium oxide ceramic rods for dental material, have been used as negative controls.
