Sintered metal materials, excluding hardmetals - Determination of transverse rupture strength (ISO/DIS 3325:2024)
Gives a method for the determination of the transverse rupture strength of sintered metals, excluding hardmetals. Particularly suitable for comparing the sintered strength of a batch of metal powder with that of a reference powder or with a reference strength.

Matériaux métalliques frittés à l'exclusion des métaux-durs - Détermination de la résistance à la rupture transversale (ISO/DIS 3325:2024)
La présente Norme internationale prescrit une méthode pour la détermination de la résistance à la rupture transversale des matériaux métalliques frittés, à l'exclusion des métaux-durs. Cette méthode est particulièrement adaptée à la comparaison de la résistance à l'état fritté d'un lot de poudre métallique à celle d'une poudre ou à une valeur de résistance de référence. La présente méthode est applicable aux matériaux métalliques frittés, à l'exclusion des métaux-durs, qu'ils aient ou non été soumis à un traitement thermique après frittage, ainsi qu'aux matériaux calibrés ou matricés après frittage. Elle est avant tout applicable aux matériaux de dureté uniforme dans la totalité de leur section et de ductilité négligeable, c'est-à-dire de ductilité correspondant à une déformation rémanente, résultant de l'essai et mesurée entre les deux supports, inférieure à 0,5 mm environ (voir note 1). Si l'essai est effectué sur des matériaux se trouvant dans des conditions autres que celles prescrites ci-dessus, les nouvelles conditions doivent être indiquées. NOTE 1 La déformation rémanente peut être mesurée avec une précision suffisante sur les deux fragments d'un barreau cassé ou d'un barreau fissuré par repérage de la surface inférieure. Il est également possible de mesurer, à l'aide d'un dispositif optique (microscope de mesure, comparateur optique, etc.) la courbure d'une droite tracée horizontalement sur le côté du barreau.

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).
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.
