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
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 collaborates 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 Standards. 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 this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10993-1 was prepared by Technical Committee ISO/TC 194, Biological evaluation of medical devices.

ISO 10993-1:2003(E)
Introduction
This part of ISO 10993 is a combination/harmonization of numerous international and national standards and
guidelines concerning the biological evaluation of medical devices. It is intended to be the overall guidance
document for the selection of tests enabling evaluation of biological responses relevant to the safety of
medical devices and materials.
The role of this part of ISO 10993 is to serve as a framework in which to plan such a biological evaluation
which minimizes the number and exposure of test animals.
The protection of humans is the primary goal of ISO 10993.
The appropriate selection and interpretation of biological evaluation tests requires an understanding of the
rationale behind such testing. An informative rationale for the use of this part of ISO 10993 is provided in
Annex A. Annex B contains a flow chart to aid in the systematic approach to the biological evaluation of
medical devices. A bibliography is given at the end of the text.

INTERNATIONAL STANDARD ISO 10993-1:2003(E)
Biological evaluation of medical devices —
Part 1:
Evaluation and testing
1 Scope
This part of ISO 10993 describes
a) the general principles governing the biological evaluation of medical devices;
b) the categorization of devices based on the nature and duration of their contact with the body;
c) the selection of appropriate tests.
This part of ISO 10993 does not cover testing of materials and devices that do not come into direct or indirect
contact with the patient's body, nor does it cover biological hazards arising from any mechanical failure.
NOTE Other parts of ISO 10993 cover specific tests (see also the rationale in A.2).
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
medical device
any instrument, apparatus, appliance, material or other article, including software, whether used alone or in
combination, intended by the manufacturer to be used for human beings solely or principally for the purpose
of:
diagnosis, prevention, monitoring, treatment or alleviation of disease;
diagnosis, monitoring, treatment, alleviation of or compensation for an injury or handicap;
investigation, replacement or modification of the anatomy or of a physiological process;
control of conception;
and which does not achieve its principal intended action in or on the human body by pharmacological,
immunological or metabolic means, but which may be assisted in its function by such means
NOTE 1 Devices are different from drugs, and their biological evaluation requires a different approach.
NOTE 2 Use of the term “medical device” includes dental devices.
2.2
material
any synthetic or natural polymer, metal, alloy, ceramic or other nonviable substance, including tissue rendered
nonviable, used as a medical device or any part thereof

3 General principles applying to biological evaluation of medical devices
3.1 The selection and evaluation of any material or device intended for use in humans requires a structured
programme of assessment.
In the design process, an informed decision shall be made and documented that weighs the
advantages/disadvantages of the various choices of material and test procedure. To give assurance that the
final product will perform as intended and be safe for human use, the programme shall include a biological
evaluation.
The biological evaluation shall be planned, carried out and documented by knowledgeable and experienced
individuals capable of making informed decisions based on the advantages and disadvantages of the various
materials and test procedures available.
3.2 In the selection of materials to be used in device manufacture, the first consideration should be fitness
for purpose with regard to characteristics and properties of the material, which include chemical, toxicological,
physical, electrical, morphological and mechanical properties.
3.3 The following should be considered for their relevance to the overall biological evaluation of the device:
a) the material(s) of manufacture;
b) intended additives, process contaminants and residues;
c) leachable substances;
d) degradation products;
e) other components and their interactions in the final product;
f) the properties and characteristics of the final product.
NOTE If appropriate, identification and quantification of extractable chemical entities of the final product should
precede biological evaluation (see ISO 10993-9).
3.4 Tests to be used in biological evaluation, and the interpretation of the results of such tests, should take
into account the chemical composition of the materials, including the conditions of exposure and the nature,
degree, frequency and duration of exposure of the device or its constituents to the body. By following these
principles, devices can be categorized to facilitate the selection of appropriate tests (see Clause 4). This part
of ISO 10993 is concerned with the tests to be carried out on materials and/or the final product.
The range of potential biological hazards is wide and may include:
a) short-term effects (e.g. acute toxicity, irritation to the skin, eye and mucosal surfaces, sensitization,
haemolysis and thrombogenicity);
b) long-term or specific toxic effects [e.g. subchronic and chronic toxic effects, sensitization, genotoxicity,
carcinogenicity (tumorigenicity) and effects on reproduction including teratogenicity].
3.5 All potential biological hazards should be considered for every material and final product, but this does
not imply that testing for all potential hazards will be necessary or practical (see Clause 6).
3.6 Any in vitro or in vivo tests shall be based on end-use applications and appropriate good laboratory
practice followed by evaluation by competent informed persons. Whenever possible, in vitro screening should

---------------------- Page: 12 ----------------------
ISO 10993-1:2003(E)
be carried out before in vivo tests are commenced. Test data, complete to the extent that an independent
analysis could be made, shall be retained (see A.2, “Subclause 3.6”).
3.7 The materials or final product shall be considered for biological re-evaluation if any of the following
occurs:
a) any change in the source or in the specification of the materials used in the manufacture of the product;
b) any change in the formulation, processing, primary packaging or sterilization of the product;
c) any change in the final product during storage;
d) any change in the intended use of the product;
e) any evidence that the product may produce adverse effects when used in humans.
3.8 The biological evaluation performed in accordance with this part of ISO 10993 should be considered in
conjunction with the nature and mobility of the ingredients in the materials used to manufacture the device and
other information, other non-clinical tests, clinical studies and post-market experience for an overall
assessment (see A.2, “Subclause 3.8”).
4 Categorization of medical devices
4.1 General
Following the general principles laid down in Clause 3, medical devices can be categorized to facilitate the
selection of appropriate tests.
The testing of any device that does not fall into one of the categories described should follow the general
principles contained in this part of ISO 10993. Certain devices may fall into more than one category, in which
case testing appropriate to each category should be considered.
Medical devices shall be categorized according to the nature and duration of body contact as described in 4.2
and 4.3.
4.2 Categorization by nature of body contact
4.2.1 Non-contact devices
Medical devices that do not contact the patient's body directly or indirectly are not included in the scope of
ISO 10993.
4.2.2 Surface-contacting devices
These include medical devices in contact with the following surfaces:
a) skin: devices that contact intact skin surfaces only; examples include electrodes, external prostheses,
fixation tapes, compression bandages and monitors of various types;
b) mucosal membranes: devices that contact intact mucosal membranes; examples include contact lenses,
urinary catheters, intravaginal and intraintestinal devices (stomach tubes, sigmoidoscopes, colonoscopes,
gastroscopes), endotracheal tubes, bronchoscopes, dental prostheses, orthodontic devices and
intrauterine devices;
c) breached or compromised surfaces: devices that contact breached or otherwise compromised body
surfaces; examples include dressings, healing devices and occlusive patches for ulcers, burns and
granulation tissue.
