ISO/TR 14786 is intended to provide information and analyses in support of the development of chemical nomenclature for the naming of “nano-objects”. “Nano-objects” have been defined in ISO/TS 80004- 1:2010 to mean “materials with one, two, or three external dimensions in the nanoscale”, with the nanoscale defined as the “size range from approximately 1 nm to 100 nm”. Nano-objects are further defined as nanoplates, nanofibres, and nanoparticles. More specifically, the nano-objects that are the subject of this Technical Report are discrete chemical entities rather than devices or mixtures (preparations). The nano-objects discussed in this Technical Report are not intended to constitute an exhaustive list. This Technical Report is intended to facilitate communications between developers and potential users of nomenclature including academia, industry, government and non-governmental organizations.
