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.
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 on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 194, Biological and clinical evaluation of medical
devices, in collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 206, Biocompatibility of medical and dental materials and devices, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 10993-6:2016), which has been technically
revised.
The main changes are as follows:
— Informative elements of the scope have been moved to a new introduction clause;
— New definitions for “comparative material”, “coupon”, “euthanasia”, “local effect”, “location marker” and
“steady- state” have been added to clause 3;
— New paragraph on the use of smaller compositionally representative samples or coupons has been added
to 4.2.2;
— New 4.3 “Selection of control materials” has been added;
— Clause 4 and Clause 5 have been revised;
— New Annex E “Test methods for devices contacting peripheral nerve tissue” and Annex G “Microscopic
evaluation of tissue responses to implanted materials” have been added;
— The old Annex E was moved to Annex F;
— Updated entries in the bibliography;
— Document has been revised e
