Implants for surgery — Ultra-high-molecular-weight polyethylene — Part 2: Moulded forms
This document specifies the requirements and corresponding test methods for moulded forms (e.g. sheets, rods and near net shape bars) made from ultra-high-molecular-weight polyethylene (UHMWPE) powder for use in the manufacture of surgical implants. This document is not applicable to moulded forms that were intentionally irradiated, that were made from UHMWPE blended with additives or UHMWPE blended with different forms of polyethylene, and the packaged and sterilized finished implant.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

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.

Introduction
While no known surgical implant material has ever been shown to cause absolutely no adverse reactions in
the human body, long-term clinical experience with the material referred to in this document has shown that
an acceptable level of biological response can be expected when the material is used in appropriate
applications. However, this document covers the raw material and not finished medical devices, where the
design and fabrication of the device can impact biological response.
