Spotlight July 2022: New definition on nanomaterials published
The European Union has published a new definition for nanomaterials as of June 2022. It is recommended that this be used as a basis for future legislation. The new documents can be found on the EC website.
In the new “nanodefinition”, the essential components such as the origin or the size range of the particles (1-100 nm) remain mostly unchanged, but some aspects are simplified that were only included in the old definition from 2011 through explicit extensions. For example, nanomaterials with dimensions below one nanometre, such as some nanotubes and graphene, which were previously explicitly included, are now included generically. For this purpose, elongated particles with two external dimensions smaller than 1 nm and one dimension larger than 100 nm as well as platelet-like particles with one dimension smaller than 1 nm and two dimensions larger than 100 nm are newly taken into account. Particles with two orthogonal external dimensions larger than 100 µm no longer have to be taken into account.
Likewise, some decision criteria have been clarified and simplified. The previous criterion that a material with a volume specific surface area (VSSA) of 60 m2/cm3 or more was classified as nano has now been dropped. Conversely, in future a material can be designated as non-nano if the VSSA is smaller than 6 m2/cm3. Finally, the threshold for the particle number-based size distribution in the new definition is no longer flexible, but fixed at 50 %.
