Nanotechnologies - Characteristics of working suspensions of nano-objects for in vitro assays to evaluate inherent nano-object toxicity (ISO 19337:2023)
This document describes the characteristics of working suspensions of nano-objects to be considered when conducting in vitro assays to evaluate inherent nano-object toxicity. In addition, the document identifies applicable measurement methods for these characteristics.
This document is applicable to nano-objects, and their aggregates and agglomerates greater than 100 nm.
This document intends to help clarify whether observed toxic effects come from tested nano-objects themselves or from uncontrolled sources.
Nanotechnologien - Eigenschaften von Arbeitssuspensionen von Nanoobjekten für In-vitro-Assays zur Bewertung der inhärenten Nanoobjekt-Toxizität (ISO 19337:2023)
Dieses Dokument beschreibt die Eigenschaften von Arbeitssuspensionen von Nanoobjekten, die bei der Durchführung von In vitro-Assays zur Bewertung der inhärenten Nanoobjekt-Toxizität zu berücksichtigen sind. Darüber hinaus werden in diesem Dokument anwendbare Messverfahren für diese Eigenschaften identifiziert.
Dieses Dokument ist anwendbar für Nanoobjekte und ihre Aggregate und Agglomerate mit einer Größe von mehr als 100 nm.
Das Dokument ist dafür vorgesehen, zu klären, ob beobachtete toxische Wirkungen von den geprüften Nanoobjekten selbst oder von unkontrollierten Quellen stammen.
Nanotechnologies - Caractéristiques des suspensions de nano-objets utilisées pour les tests in vitro évaluant la toxicité inhérente aux nano-objets (ISO 19337:2023)
Le présent document décrit les caractéristiques des suspensions de nano‑objets à prendre en considération pour les essais in vitro évaluant la toxicité inhérente aux nano‑objets. En outre, il identifie les méthodes de mesure applicables à ces caractéristiques.
Le présent document est applicable aux nano‑objets, ainsi qu’à leurs agrégats et agglomérats d’une taille supérieure à 100 nm.
Le présent document a pour objectif de clarifier si les effets toxiques observés proviennent des nano‑objets soumis à essai ou de sources non contrôlées.

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 document 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.
