Sintered-metal injection-moulded materials - Specifications (ISO 22068:2012)
ISO 22068:2012 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.
Sintermetallpulverspritzguss - Anforderungen (ISO 22068:2012)
Diese Internationale Norm legt Anforderungen an die chemische Zusammensetzung sowie an mechanische und physikalische Eigenschaften von spritzgegossenen pulvermetallurgischen Werkstoffen fest.
Sie dient dem Ziel, Konstrukteure und Werkstofftechniker mit Informationen zu versorgen, die zum Festlegen von Werkstoffen notwendig sind, aus denen Teile ausschließlich durch Metallpulverspritzguss (MIM) herzustellen sind.
Diese Norm darf nicht auf Konstruktionsteile angewendet werden, die nach anderen pulvermetallurgischen Verfahren hergestellt werden, wie z. B. Presssinter und Pulverschmiedetechniken.
Matériaux métalliques frittés pour moulage par injection - Spécifications (ISO 22068:2012)
L'ISO 22068:2012 spécifie les exigences relatives à la composition chimique et aux propriétés physiques et mécaniques des matériaux métalliques frittés moulés par injection.
Elle a pour but de fournir aux ingénieurs spécialisés dans la conception et les matériaux, les informations nécessaires pour spécifier les matériaux constitutifs de composants fabriqués par le procédé de moulage par injection métallique (MIM) uniquement.
Elle ne s'applique pas aux pièces structurelles fabriquées par d'autres procédés de la métallurgie des poudres, telles que les technologies du forgeage de poudre ou de la compression-frittage.
Sintrani kovinski, brizgano liti materiali - Specifikacije (ISO 22068:2012)
EN ISO 22068 določa zahteve za kemično sestavo ter mehanske in fizične lastnosti sintranih kovinskih, brizgano litih materialov. Njegov namen je inženirjem oblikovanja in materialov zagotoviti potrebne informacije za določanje materialov in sestavnih delov, proizvedenih samo s procesom kovinskega brizganega litja. Ne velja za strukturne dele, proizvedene na druge načine metalurgije prahu, kot je tehnologija sintranja pod pritiskom ali kovanje iz prahu.

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,
