Metallic powders - Determination of particle size by dry sieving (ISO 4497:2020)

This document specifies a method of determining the particle size distribution of metallic powders by dry sieving into size fractions.
The method is applicable to dry, unlubricated metallic powders, but not applicable to powders in which the morphology differs markedly from being equiaxial, for example flake-type powders.
The method is not applicable to metallic powders having a particle size wholly or mostly under 45 µm.

Metallpulver - Bestimmung der Teilchengröße durch Trockensiebung (ISO 4497:2020)

Dieses Dokument legt das Verfahren zur Bestimmung der Teilchengrößenverteilung metallischer Pulver durch Trockensiebung in Größenfraktionen fest.
Das Verfahren ist anwendbar auf trockene, gleitmittelfreie Metallpulver, aber nicht auf Pulver, deren Partikelform stark von der Kugelgestalt abweicht, z. B. auf Pulver mit Partikeln in Flockenform.
Das Verfahren ist nicht anwendbar auf metallische Pulver mit einer Teilchengröße, die insgesamt oder überwiegend unter 45 µm liegt.

Poudres métalliques - Détermination de la granulométrie par tamisage à sec (ISO 4497:2020)

Le présent document spécifie une méthode de détermination de la distribution granulométrique des poudres métalliques par tamisage à sec en fractions granulométriques.
La méthode est applicable aux poudres métalliques sèches et non lubrifiées, mais non aux poudres dont la morphologie diffère notablement de l'équiaxialité, par exemple aux poudres en flocons.
La méthode n'est pas applicable aux poudres métalliques de granulométrie inférieure, en totalité ou en partie, à 45 µm.

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).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.
