The committee of Iranian nanotechnology standardization chose 49 main words in nanotechnology by means of ISO, BSI, and ASTM published standards and translated their definitions into Persian in cooperation with a team from Persian Language and Literature Academy.
The words like nanotechnology, nanomaterials, nanoparticle, nanoscale, nanotube, nanosystem etc have been defined in this standard.
