Nanomaterials - Quantification of nano-object release from powders by generation of aerosols (ISO/TS 12025:2021)

This document describes methods for the quantification of nano-object release from powders as a result of treatment, ranging from handling to high energy dispersion, by measuring aerosols liberated after a defined aerosolization procedure. Particle number concentration and size distribution of the aerosol are measured and the mass concentration is derived. This document provides information on factors to be considered when selecting among the available methods for powder sampling and treatment procedures and specifies minimum requirements for test sample preparation, test protocol development, measuring particle release and reporting data. In order to characterize the full size range of particles generated, the measurement of nano-objects as well as agglomerates and aggregates is adressed in this document.
This document does not include the characterization of particle sizes within the powder. Tribological methods are excluded where direct mechanical friction is applied to grind or abrade the material.

Nanomaterialien - Quantifizierung der Freisetzung von Nanoobjekten aus Pulvern durch Aerosolerzeugung (ISO/TS 12025:2021)

Dieses Dokument beschreibt Verfahren zur Quantifizierung der Nanoobjekt-Freisetzung aus Pulvern als Ergebnis des gesamten Verfahrens, vom Handling bis zu hoch-energetischer Dispergierung, durch Messung des entstehenden Aerosols nach definierter Pulverbeanspruchung. Partikelanzahlkonzentration und  größenverteilung des Aerosols werden gemessen und die Massenkonzentration abgeleitet. Dieses Dokument liefert Angaben über zu beachtende Faktoren bei der Auswahl unter den zur Verfügung stehenden Verfahren zur Probennahme und Behandlung von Pulvern und legt Mindestanforderungen an die Probenherstellung, die Erarbeitung des Prüfprotokolls, die Messung der Partikelfreisetzung und die anzugebenden Daten fest. Damit der vollständige Größenbereich der erzeugten Partikel charakterisiert werden kann, wird in diesem Dokument neben der Messung von Nanoobjekten auch die Messung von Agglomeraten und Aggregaten behandelt.
Dieses Dokument behandelt nicht die Charakterisierung von Partikelgrößen innerhalb des Pulvers. Tribologische Verfahren, bei denen das Material mittels direkter mechanischer Reibung bearbeitet wird, um es abzureiben oder zu schleifen, sind ausgeschlossen.

Nanomatériaux - Quantification de la libération de nano-objets par les poudres par production d'aérosols (ISO/TS 12025:2021)

Le présent document décrit des méthodes pour la quantification de la libération de nano-objets par les poudres en conséquence d’un traitement, allant de la manipulation à une dispersion à haute énergie, par mesurage des aérosols libérés après un mode opératoire défini d’aérosolisation. La concentration en nombre de particules et la distribution granulométrique de l’aérosol sont mesurées et la concentration massique est calculée. Le présent document fournit des informations sur les facteurs à prendre en compte pour la sélection des méthodes pour l’échantillonnage des poudres et les modes opératoires de traitement. Il spécifie également les exigences minimales pour la préparation des échantillons d’essai, le développement du protocole d’essai, le mesurage de la libération de particules et la consignation des données. Afin de caractériser toute la plage granulométrique des particules générées, le mesurage des nano-objets ainsi que des agglomérats et des agrégats est addressé dans le présent document.
Le présent document n’inclut pas la caractérisation granulométrique des particules au sein de la poudre. Les méthodes tribologiques sont exclues lorsqu’un frottement mécanique direct est appliqué pour broyer ou éroder le matériau.
