Nanotechnologies – Characteristics of working suspensions of nano-objects for in vitro assays to evaluate inherent nano-object toxicity

This ISO 19337 describes 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 larger than 100 nm. NOTE – This ISO19337 intends to help clarify whether observed toxic effects come from tested nano-objects themselves or from uncontrolled sources.
