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

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www. iso. org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

— Clarification on atypical BSE types, especially in combination with intracranial applications;

— Enhanced expectation of using validated biochemical testing to establish TSE presence;

Animal tissues and their derivatives are used in the design and manufacture of medical devices to

provide performance characteristics that have been chosen for advantages over non-animal based

materials. The range and quantities of materials of animal origin in medical devices vary. These

materials can comprise a major part of the device (e.g. bovine/porcine heart valves, bone substitutes

for use in dental or orthopaedic applications, haemostatic devices), can be a product coating or

impregnation (e.g. collagen, gelatine, heparin), or can be used in the device manufacturing process (e.g.

tallow derivatives such as oleates and stearates, foetal calf serum, enzymes, culture media).

Tissues and derivatives for use in medical devices are typically obtained by the manufacturer from a

range of sources such as animal herds or flocks and commercial harvesting (including fishing). Some

specialized industries also process materials of animal origin to manufacture a finished product (e.g.

gelatine) which is incorporated as a raw material into the finished medical device by the manufacturer.

To show compliance with this document, its specified requirements should be fulfilled. The guidance

given in the notes and informative annexes is not normative and is not provided as a checklist for

This document specifies requirements for controls on the sourcing, collection, and handling (which

includes storage and transport) of animals and tissues for the manufacture of medical devices utilizing

materials of animal origin other than in vitro diagnostic medical devices. It applies where required by

NOTE 1 Selective sourcing is considered to be especially important for transmissible spongiform

encephalopathy (TSE) risk management, i.e. when utilising animal tissue and/or their derivative originating

In addition, local safety regulation may be applied to ensure a clean basic handling of animals towards

viral and bacterial loads (see also 5.5). The manufacturers should refer to ISO 22442-3 for information

on the validation of the elimination and/or inactivation of viruses and TSE agents.

This document does not cover the utilization of human tissues in medical devices.

This document does not specify a quality management system for the control of all stages of production

It is not a requirement of this document to have a full quality management system during manufacture,

but it does specify requirements for some of the elements of a quality management system. Attention

is drawn to the standards for quality management systems (see ISO 13485) that control all stages of

production or reprocessing of medical devices. The quality management system elements that are

required by this document can form a part of a quality management system conforming to ISO 13485.

NOTE 2 A general principle for the application of this International Standard is that it is advisable to give due

consideration to the requirements and recommendations contained in all three parts of the standard.

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

It is the responsibility of the manufacturer to ensure that the material is fit for its intended use.

For each material or derivative, the risk of certain diseases is dependent on the animal species and

possibly strain, and this shall be taken into account for the establishment of control measures.

The risk of certain diseases is dependent on the geographical origin and this shall be taken into account

Geographical origin can include conception, birth, rearing, and slaughtering (for bovine species, see

recorded if known. The use of wild mammalian species shall be addressed in the risk assessment (see

Sourcing of animal material shall be subject to control and individual inspection by a veterinarian.

There will, however, be some source-species where this is not possible (e.g. fish, crustaceans). If

individual animals cannot be inspected, the justification for this shall be documented and a relevant

Bovine, caprine, cervid, equine, ovine, and porcine species shall be subject to ante-mortem veterinary

inspection. Animals showing locomotive system abnormalities or neurological disorders shall not be

used for the production of medical devices except for tallow derivatives, animal charcoal, and amino

acids that are acceptable as discussed in ISO/DIS 22442-1:2018, 4.4.2 and 4.4.3, due to their processing

Prior to certification, a post-mortem inspection of bovine, caprine, cervid, equine, ovine, and porcine

species shall be performed by a veterinarian immediately after slaughter according to local custom and

Where indicated by risk assessment, for materials (including pooled blood supplies) for direct use

in medical devices and that are not subject to a validated process to reduce TSE risk in line with

ISO 22442-3, consideration shall be given to the application of a validated biochemical test for the

Animal tissues derived from certain species (e.g. fish, crustaceans) require a modified approach since

veterinary surveillance is not practicable in the same way as for other animal tissues. Manufacturers

should apply relevant sections of this document to such materials, but may need to rely on other

procedures which have been shown to be effective for risk reduction (see ISO/DIS 22442-1).

Material of animal origin intended for utilization in medical devices shall originate from animals

confirmed by a veterinarian as being fit for human consumption. Records to demonstrate conformance

with veterinary inspection criteria at the abattoir, certificate details, and source shall be available (see

for example, Annex B). For species where such certification by a veterinarian cannot be obtained, a status

equivalent to “fit for human consumption” is required such as a confirmation of apparent good health.

Where the risk management undertaken according to ISO/DIS 22442-1 indicates that it is both necessary

and feasible, a traceability system shall be established. The extent of traceability shall be defined by the

outcome of the risk assessment taking into account those official information systems that exist.

NOTE Traceability may not be practicable if materials of animal origin are collected, pooled, and
