Nanotechnologies - Characteristics of working suspensions of nano-objects for in vitro assays to evaluate inherent nano-object toxicity (ISO 19337:2023) prEN ISO 19337

Scope

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.
