ISO/TS 12901-2:2026

This document establishes and gives guidance on the use of a control banding approach for controlling the risks associated with occupational exposures to nano-objects and their aggregates and agglomerates greater than 100nm (NOAA), even if knowledge regarding their toxicity and quantitative exposure estimations is limited or lacking.

This document applies to inhalation control, for which the control banding tool is specifically designed.

NOTE Some guidance for skin and eye protection is given in ISO/TS12901-1.

This document does not apply to materials of biological origin.

This document is intended to help businesses and others, including research organizations engaged in the manufacturing, processing, or handling of NOAA, by providing an easy-to-understand, pragmatic approach to controlling occupational exposures.
