ISO 22068:2012(E)
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 22068 was prepared by Technical Committee ISO/TC 119, Powder metallurgy, Subcommittee SC 5,
Specifications for powder metallurgical materials (excluding hardmetals).

INTERNATIONAL STANDARD ISO 22068:2012(E)

Sintered-metal injection-moulded materials — Specifications
1 Scope
This International Standard specifies the requirements for the chemical composition and the mechanical and
physical properties of sintered-metal injection-moulded materials.
It is intended to provide design and materials engineers with necessary information for specifying materials in
components manufactured by means of the Metal Injection Moulding (MIM) process only.
It does not apply to structural parts manufactured by other powder metallurgy routes, such as press-and-sinter
or powder-forging technologies.
