Nanomaterials - Quantification of nano-object release from powders by generation of aerosols (ISO/TS 12025:2012)
ISO/TS 12025:2012 provides methodology 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. In addition to information in terms of mass, the aerosol is characterized for particle concentrations and size distributions.
ISO/TS 12025:2012 provides information on factors to be considered when selecting from 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 recommended in ISO/TS 12025:2012.
Nanomaterialien - Quantifizierung der Freisetzung von Nanoobjekten aus Pulvern durch Aerosolerzeugung (ISO/TS 12025:2012)
Diese Technische Spezifikation liefert eine Methodik 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. Neben gravimetrischen Angaben, wird das entstehende Aerosol über die Partikelanzahlkonzentration und Partikelgrößenverteilung beschrieben. Diese Technische Spezifikation liefert Angaben über zu beachtende Faktoren bei der Auswahl aus den zur Verfügung stehenden Verfahren zur Probennahme als auch der Beanspruchung 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 beschrieben werden kann, wird in dieser Technischen Spezifikation neben der Messung von Nanoobjekten auch die Messung von Agglomeraten und Aggregaten empfohlen.
Diese Technische Spezifikation 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 von dieser Technischen Spezifikation ausgenommen.
Nanomatériaux - Quantification de la libération de nano-objets par les poudres par production d'aérosols (ISO/TS 12025:2012)
L'ISO/TS 12025:2012 fournit une méthodologie 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. Outre les informations en termes de masse, la caractérisation de l'aérosol concerne les concentrations de particules et les distributions granulométriques.
L'ISO/TS 12025:2012 fournit des informations sur les facteurs à prendre en compte lors de la sélection parmi les méthodes disponibles pour l'échantillonnage des poudres et les modes opératoires de traitement. Elle 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 produites, le mesurage des nano-objets, ainsi que des agglomérats et des agrégats, est recommandé dans l'ISO/TS 12025:2012.

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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 %
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
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.

Introduction
The emissions or release of nano-objects into the surrounding air from powdered nanostructured
materials resulting from handling is an important consideration in the design and operation of many
industrial processes. Released nano-objects may affect human health and the environment, depending
on the nature and quanitity of the nanomaterial. It is therefore important to obtain data about the
propensity of nanomaterials to release nano-objects, thereby allowing exposure to be evaluated,
controlled and minimised.
Three main target groups of experts for the evaluation of the release of nano-objects from powdered
nanostructured materials are:
— material scientists and engineers, who design safe nanomaterials and safe nanomaterial
handling processes;
— occupational, health and safety specialists;
— environmental specialists, who need exposure data in addition to toxicity data for risk assessment
of manufactured nanomaterials (see A.2) and who collect dustiness data (gravimetric as well as
particle concentration and particle size information).
The propensity of nanomaterials to release nano-objects into the air is determined by test methods
devised to apply energy to a sample to stress the intra-particle bonds. This stressing induces abrasion,
erosion or comminution, which causes dissemination of the particles into the gaseous phase,
