Scope: The effects of synthetic nanoparticles on human health and the environment are still poorly understood and therefore uncertain. In particular, it is unclear in which areas nanoparticles-dose caused negative effects in the organism or in the environment (unknown dose-response relationship). The underlyingtoxicological mechanisms and possible effects of nanoparticle exposure over long periods of time are poorly understood.

In product advertisements on the Internet and in reports in international journals, especially the functional properties of "nanotextiles" are described. The type of integration of the nanoparticles in textiles is often described only sparsely. Therefore, the present document is based primarily on research studies that include information on the integration of the nanoparticles in the textile material.

The purpose of the present document is to give some guidance on tests to nanoparticle release. Thedetermination of the release of nanoparticles could be performed either through quantification bychemical analysis (5.1), or by determining the linting (5.2), for example.Cross References:ISO/TS 18110:2015CEN ISO/TS 80004-1 (ISO/TS 80004-1:2015)CEN ISO/TS 80004-12:2017ISO 19430:2016EN ISO 105-C06EN ISO 105-E04 EN ISO 9073-10EN 16711-2:2015EN ISO 17294-2EN ISO 11885
