Latest draft of that document (Jan 2017): https://echa.europa.eu/documents/10162/13564/appendix_4_nano_registration_committees_en.pdf/1abb12d1-88a2-b386-0907-c67d05105378

It writes:

"A 'nanoform' is a substance that meets the requirements of the Commission Recommendation for the definition of nanomaterial [refs] (hereafter, the definition of nanomaterials) and has a shape and a surface chemistry."

Discussion started with the WG4... for now, I will await a clear or at least final definition.

"According to Annex VI of the REACH Regulation, a “nanoform” is a form of a natural or manufactured substance2 containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm-100 nm, including also by derogation fullerenes, graphene flakes and single wall carbon nanotubes with one or more external dimensions below 1 nm."
