Sintered metal materials, excluding hardmetals - Determination of transverse rupture strength (ISO 3325:1996)

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.

Sintermetalle, ausgenommen Hartmetalle - Ermittlung der Biegebruchfestigkeit (ISO 3325:1996)

Diese Internationale Norm legt ein Verfahren zur Ermittlung der Biegebruchfestigkeit von Sintermetallen, ausgenommen Hartmetalle, fest. Dieses Verfahren ist speziell für den Vergleich der Sinterfestigkeit eines Metallpulver-Loses mit einem Refezenz-Pulver oder -Festigkeitswert geeignet. Dieses Verfahren ist anwendbar bei Sintermetallen, ausgenommen bei Hartmetallen, gleichgültig, ob sie nach dem Sintern einer Wärmebehandlung unterzogen wurden oder nicht, sowie bei Werkstoffen, die nach dem Sintern kalibriert wurden.

Matériaux métalliques frittés a l'exclusion des métaux-durs - Détermination de la résistance a la rupture transversale (ISO 3325:1996)

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.

IS0 3325: 1996(E) Foreword IS0 (the International Organization for Standardization) is a worldwide fed- eration of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep- resented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 col- laborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are cir- culated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 3325 was prepared by Technical Committee lSO/TC 119, Powder metallurgy, Subcommittee SC 3, Sampling and test- ing methods for sin tered metal materials (excluding hardme tals). This second edition cancels and replaces the first edition (IS0 3325:1975), which has been technically revised. 0 IS0 1996 All rights reserved.

INTERNATIONAL STANDARD @ IS0 IS0 3325: 1996(E) Sintered metal materials, excluding hardmetals - Determination of transverse rupture strength 1 Scope This International Standard specifies a method for the determination of the transverse rupture strength of sintered metal materials, excluding hardmetals. The method is particularly suitable for comparing the sin- tered strength of a batch of metal powder with that of a reference powder or with a reference strength. The method is applicable to sintered metal materials, excluding hardmetals, whether they have been sub- jected to heat treatment after sintering or not, and also to materials that have been sized or coined after sintering. It is specially suitable for materials having a uniform hardness throughout their section and negligible duc- tility, i.e. a ductility corresponding to a permanent deformation of less than about 0,5 mm measured between the two supports during the transverse rup- ture strength determination. If the test is applied to materials under conditions other than those specified above, the conditions shall be reported. NOTE 1 The permanent deformation can be measured with sufficient precision from the two fragments of the broken or cracked bar by indexing the lower surface. Alter- natively, the deflection of a straight line drawn horizontally on the side of the test piece can be measured using an optical instrument such as a measuring microscope or optical comparator. 2 Principle A test piece resting on two supports is broken by the . application of a load at the midpoint between the sup- ports, under short-term static loading condit
