Biological evaluation of medical devices - Part 2: Animal welfare requirements (ISO 10993-2:2022)
This document 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 biocompatibility of materials used in medical devices. It is aimed at those who commission, design and perform tests or evaluate data from animal tests undertaken to assess the biocompatibility of materials intended for use in medical devices, or that of the medical devices themselves.
This document 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 other scientifically valid means not requiring animal tests.
This document applies to tests performed on living vertebrate animals, other than man, to establish the biocompatibility of materials or medical devices.
This document does not apply to tests performed on invertebrate animals and other lower forms; nor (other than 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.
Biologische Beurteilung von Medizinprodukten - Teil 2: Tierschutzbestimmungen (ISO 10993-2:2022)
Dieses Dokument legt die Mindestanforderungen fest, die zu erfüllen sind, um sicherzustellen und nachzuweisen, dass die richtigen Vorkehrungen getroffen wurden, um Schmerzen und Leiden, die sich nachteilig auf die Validität der Daten auswirken können, auf ein Mindestmaß herabzusetzen. Dieses Dokument richtet sich an den Personenkreis, der Versuche in Auftrag gibt, sie plant und durchführt oder die Daten auswertet, um die Bioverträglichkeit von Materialien, die für die Verwendung in Medizinprodukten vorgesehen sind, oder von Medizinprodukten selbst, zu beurteilen.
In diesem Dokument werden Empfehlungen gegeben und eine Anleitung angeboten, deren Ziel eine weitere Verminderung der Gesamtzahl der verwendeten Tiere, eine Verbesserung der Prüfverfahren zur Verringerung oder Ausschaltung von Schmerz oder Leiden bei Tieren, und der Ersatz von Tierversuchen durch andere wissenschaftlich valide Mittel ist, bei denen Tierversuche nicht erforderlich sind, ist.
Dieses Dokument gilt für Versuche an lebenden Wirbeltieren, außer dem Menschen, zur Feststellung der Bioverträglichkeit von Materialien oder Medizinprodukten.

Introduction
The goal of the ISO 10993 series is the protection of humans in the context of the use of medical devices.
This document 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 properties 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 testing and enhance the welfare of
the animals used.

4 Requirements
4.1 General
This document sets forth essential requirements when animal tests are being considered, planned or
performed for the biological evaluation 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 subsequently be performed.
This document 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 document requires that the need to perform animal tests is justified, and any pain, suffering,
distress or lasting harm that is caused during essential animal tests is minimized.

---------------------- Page: 15 ----------------------
SIST EN ISO 10993-2:2023
ISO 10993-2:2022(E)
This document sets out essential requirements that safeguard animal welfare by minimizing the pain
and distress caused when animal tests are considered or undertaken by:
— establishing a framework that reflects the relevant ethical and, in many jurisdictions, the legal
considerations relating to the use of animals for experimental or other scientific purposes;
— minimizing the number of animal tests by the appropriate use of literature searches, data-sharing,
validated replacement alternatives, and appropriate testing strategies and study designs;
— minimizing any pain, suffering, distress and lasting harm caused to animals used in tests to evaluate
the biocompatibility of materials used in medical devices by requiring appropriate use of relevant
reduction and refinement alternatives;
— promoting consistent, high standards of accommodation and care to safeguard both the welfare of
the animals used and the scientific validity and the reproducibility of the data generated;
— appropriate veterinary care program overseen by a qualified laboratory animal veterinarian is
implemented.
To these ends the design and conduct of animal tests to evaluate the biocompatibility of materials
used in medical devices shall be formed by, and incorporate, relevant strategies for the replacement,
reduction and refinement of animal tests.
Commissioning animal tests without seeking and obtaining this information, exercising these
judgements and implementing these measures does not comply with the essential requirements of this
document.
NOTE These principles, and the essential requirements of this document, can also be relevant to animal use
for medical device training and development.
4.2 Justification for animal tests
When required to make proper provision to ensure human safety, animal testing to enable the proper
biological characterization of materials used in medical devices is acceptable.
For the purposes of the ISO 10993 series, animal tests shall only be deemed to be justified when:
— the resulting data are not otherwise available, but are essential to properly characterize the test
material in the context in which it is to be used;
— when no suitable scientifically validated test method not involving the use of living animals is
reasonably and practically available;
— when relevant reduction and refinement strategies have been identified and implemented including,
if appropriate, obtaining test data from manufacturers and suppliers, and literature searches for
toxicity and biocompatibility data.
To avoid unnecessary duplication, before animal tests to evaluate the biocompatibility of materials
used in medical devices are undertaken, a review of available, relevant information on the properties
of the test material shall be undertaken and documented. This shall include taking reasonable steps to
enable data sharing.
Animal tests are deemed to be justified only when:
— they have been shown to be relevant and reliable for the purposes for which they are undertaken;
— the resulting data are essential to properly characterize and evaluate the test material in the context
in which it is to be used in medical devices;
— no scientifically valid test method not requiring the use of living animals is reasonably and practically
available;

SIST EN ISO 10993-2:2023
ISO 10993-2:2022(E)
— other relevant and appropriate strategies to minimize the pain, suffering, distress and lasting harm
caused to the animals that are used have been identified and implemented.
4.3 C ompetence of personnel
Animal tests shall be designed, conducted and interpreted by persons competent to discharge the
responsibilities assigned to them.
Animal tests shall be designed and conducted with the involvement of personnel with expertise in
veterinary science, laboratory animal science and medicine, and animal husbandry and care.
Details of how staff are equipped by experience, qualification and training (including continued
professional development) to satisfy these requirements shall be documented.
NOTE 1 Although this document does not provide an objective specification, it is considered important that
those involved in the conduct of animal tests demonstrate a caring and respectful attitude to the animals used,
i.e. that they have an appropriate “culture of care”.
NOTE 2 For further information on assurance of training and competency, see 7.8.5 of Reference [1].
4.4 Planning and performanc e of animal tests
4.4.1 General
The selection and design of animal tests shall be appropriate to meet the specific scientific objectives
of the study while minimizing the pain, suffering, distress or lasting harm that can be produced to the
test animals.
As specified in 4.2, animal testing shall only be undertaken when the information required is essential
to characterize the test material, is not otherwise available and when no suitable scientifically validated
test method not involving the use of living animals is reasonably and practically available.
Following consideration of relevant and reasonably available potential replacement, reduction and
refinement strategies, and before animal tests are undertaken, principal investigators and/or sponsors
shall attest and document that no other replacement, reduction or refinement strategies are required
to minimize the animal welfare costs of the studies.
NOTE In some instances pilot studies can be required to optimize study design before definitive studies can
be designed and performed.

Introduction
The goal of the ISO 10993 series of International Standards is the protection of humans in the context of
the use of medical devices.
This document 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 properties 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, and mimimizing pain and distress to ensure the scientific validity of safety testing and
enhance the welfare of the animals used.

Biological evaluation of medical devices —
Part 2:
Animal welfare requirements
1 Scope
This document specifies the minimum requirements to be satisfied to ensure and demonstrate that
proper provision has been made to minimize pain and distress, which can negatively affect the validity
of the data. This document is for those who commission, design and perform testing or evaluate the data
to assess the biocompatibility of materials intended for use in medical devices, or that of the medical
devices themselves.
This document makes recommendations and offers guidance intended to facilitate 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 other scientifically valid means not
requiring animal tests.
This document applies to tests performed on living vertebrate animals, other than man, to establish the
biocompatibility of materials or medical devices.
This document does not apply to tests performed on invertebrate animals and other lower forms;
nor (other than 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.

4 Requirements
4.1 General
This document sets forth essential requirements when animal tests are being considered, planned or
performed for the biological evaluation of materials and 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 subsequently be performed.
This document 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.

ISO/DIS 10993-2:2020(E)
This document requires that the need to perform animal tests is justified, and any pain, suffering,
distress or lasting harm that is caused during essential animal tests is minimized.
This document sets out essential requirements that safeguard animal welfare by minimizing the pain
and distress caused when animal tests are considered or undertaken by:
— establishing a framework that reflects the relevant ethical and, in many jurisdictions, the legal
considerations relating to the use of animals for experimental or other scientific purposes;
— minimizing the number of animal tests by the appropriate use of literature searches, data-sharing,
validated replacement alternatives, and appropriate testing strategies and study designs;
— minimizing any pain, suffering, distress and lasting harm caused to animals used in tests to evaluate
the biocompatibility of materials used in medical devices by requiring appropriate use of relevant
reduction and refinement alternatives;
— promoting consistent, high standards of accommodation and care to safeguard both the welfare of
the animals used and the scientific validity and the reproducibility of the data generated.
— Implementing appropriate veterinary care program overseen by a qualified laboratory animal
veterinarian. The laboratory animal veterinarian shall have authority and responsibility for making
judgements concerning animal welfare. Veterinary advice and care shall be available at all times.
— close monitoring of animals housed in pairs or groups for signs of aggression and/or bullying; if
such signs are observed, animals should be immediately separated, and adequate veterinary care
provided, if needed.
Commissioning animal tests without seeking and obtaining this information, exercising these
judgements and implementing these measures does not comply with the essential requirements of this
document.
NOTE These principles and the essential requirements of this part of ISO 10993 can also be relevant to
animal tests conducted on medical device materials and medical devices in other contexts.
4.2 Justification for animal tests
4.2.1 General
When required to make proper provision to ensure human safety, animal testing to enable the proper
biological characterization of materials used in medical devices is acceptable.
For the purposes of the ISO 10993 series, animal tests shall only be deemed to be justified when:
a) the resulting data are not otherwise available, but are essential to properly characterize the test
material in the context in which it is to be used;
b) no suitable scientifically validated test method not involving the use of living animals is reasonably
and practically available;
c) relevant reduction and refinement strategies have been identified and implemented including, if
appropriate, obtaining test data from manufacturers and suppliers, and literature searches for
toxicity and biocompatibility data;
d) other relevant and appropriate strategies to minimize the pain, suffering, distress and lasting harm
caused to the animals that are used have been identified and implemented.
To avoid unnecessary duplication, before animal tests are undertaken to evaluate the biocompatibility
of devices or medical device materials used in medical devices are undertaken, a review of available,
relevant information on the properties of the test articles shall be undertaken and documented. This
shall include taking reasonable steps to enable data sharing.

ISO/DIS 10993-2:2020(E)
4.2.2 Oversight framework of animal use and welfare
An oversight framework of proper and ethical animal use shall be established to include the following:
— critical thought, judgment and analysis shall be used when deciding to conduct an animal study;
— scientists conducting the animal studies shall primarily be responsible for the ethical use and care
of the animals.
The ethical review committee (or equivalent institutional committee) shall ensure the ethical conduct
of animal usage. The composition of the ethical review committee shall be in accordance with national
regulations. To provide diverse opinions on animal welfare, individuals with different backgrounds
should be selected, such as scientists experienced in animal testing, qualified laboratory animal
veterinarians, persons with non-scientific background and public members to represent general
community. See A.8.1
All committee members should have appropriate training and education in ethical care and use of
animals for scientific purposes. The activities of this committee are referred to in A.8.
4.3 Competence of personnel
Animal tests shall be designed, conducted and interpreted by persons competent to discharge the
responsibilities assigned to them.
Animal tests shall be designed and conducted with the involvement of personnel with expertise in
veterinary science, laboratory animal science and medicine, and animal husbandry and care.
Details of how staff are equipped by experience, qualification and training (including continued
professional development) to satisfy these requirements shall be documented.
NOTE Although this document does not provide an objective specification, it is considered important that
those involved in the conduct of animal tests demonstrate a caring and respectful attitude to the animals used,
i.e., that they have an appropriate “culture of care”.
4.4 Planning and performance of animal tests
4.4.1 General
Following consideration of relevant and reasonably available potential replacement, reduction and
refinement strategies, and before animal tests are undertaken, principal investigators and/or sponsors
shall attest and document that no other replacement, reduction or refinement strategies are required
to minimize the animal welfare costs of the studies.
NOTE In some instances pilot studies can be required to optimize study design before definitive studies can
be designed and performed.
Where the provisions of the ISO 10993 series of International Standards require or permit that an
informed choice be made from a range of species, stages of development or animal numbers for an
animal test, the decisions taken shall both safeguard the scientific validity of the test and minimize any
pain, suffering, distress or lasting harm to the animals used. The rationale for the decisions taken shall
be documented.
4.4.2 Re-use
The need to avoid undue cumulative welfare costs to the individual animals used shall be balanced
against the need to minimize the number of animals used.
In general, an animal should not be used for more than one test.
Animals that have experienced pain and distress in the course of an animal test, or whose previous use
might influence the outcome of further tests, shall not be re-used.

oSIST prEN ISO 10993-2:2020
ISO/DIS 10993-2:2020(E)
Re-use shall be consistent with the scientific objective and shall not impose unreasonable cumulative
welfare costs on the individual animal.
Any re-use shall be documented: giving summary details of the earlier use and confirming that the
requirements set out in this subclause were considered and met.
4.5 Test strategy — Sequence of in vitro and in vivo tests
Testing strategies shall, as appropriate, adopt a tiered or hierarchical approach to minimize both the
amount of animal testing required and any pain or distress that might be caused when animal tests
are justified and undertaken. Specifically, animal tests shall not be performed before appropriate,
scientifically valid, and reasonably and practically available in vitro tests have been carried out, and the
results evaluated.
Animal tests shall not be performed if the available data (e.g. from literature and/or database searches,
results from previous screening tests, validated in vitro tests, previous animal tests or any other
available relevant evidence) provide sufficient information on the biocompatibility of the test device
or device material, including processing and geometry of the final device, for a sound, relevant risk
assessment to be undertaken in accordance with ISO 10993-1.
The rationale for the testing strategy shall be documented.
4.6 Animal care and accommodation
4.6.1 General
Purpose-bred SPF animals should be used whenever possible and specific justification is required for
the use of non-purpose bred or non-SPF animals.
High standards of care and accommodation enhance the welfare of the animals used and promote the
scientific validity of animal testing. Animal care and accommodation shall demonstrably, as a minimum,
conform to relevant, national or regional regulations, published national or international animal care,
accommodation and husbandry guidelines.
The relevant guidelines or requirements shall be referenced, and evidence of compliance (or details of
non-compliance accompanied by an assessment of its likely impact on the welfare of the animals used
and the validity of the data obtained) shall be explained, justified and documented.
Adequate acclimatization period should be considered after the animal transportation. Generally, 7
days may be appropriate for most cases.
Any component of the husbandry system that does not make best provision for the welfare of the test
animals, and that might compromise the scientific validity of the test or inappropriately influence the
nature or int
