Overview
ISO/TS 11353:2026 specifies a standardized test method for detecting the release of nano-objects from mask media. This technical specification applies to surgical masks, surgical respirator masks, and barrier face coverings-both reusable and disposable-containing nano-objects, regardless of the production technology. The standard also provides detailed procedures for sampling and qualitative characterization of released nano-objects. Its main objective is to support the assessment of potential exposure risks to humans arising from the release of nano-objects, thereby contributing to human health and safety.
With the increasing integration of nanotechnologies into filter media for enhanced performance, understanding and controlling the possible release of nano-objects during mask use is essential. This standard aims to fill the gap in international guidelines for evaluating exposure due to nano-object release, supporting regulatory, manufacturing, and market requirements.
