Scope:

The purpose of this part of ISO/TS 12901 is to describe 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 100 nm (NOAA), even if knowledge regarding their toxicity and quantitative exposure estimations is limited or lacking. 

The ultimate purpose of control banding is to control exposure in order to prevent any possible adverse effects on workers' health. The control banding tool described here is specifically designed for inhalation control. Some guidance for skin and eye protection is given in ISO/TS 12901-1. 

This part of ISO/TS 12901 is focused on intentionally produced NOAA that consist of nano-objects such as nanoparticles, nanopowders, nanofibres, nanotubes, nanowires, as well as of aggregates and agglomerates of the same. As used in this part of ISO/TS 12901, the term "NOAA" applies to such components, whether in their original form or incorporated in materials or preparations from which they could be released during their lifecycle. However, as for many other industrial processes, nanotechnological processes can generate by-products in the form of unintentionally produced NOAA which might be linked to health and safety issues that need to be addressed as well. 

Project need:

To review the standard for its 5-year review period.
