ČSN P CEN ISO/TS 17200 As is commonly noticed for every technology concerned with the development of new materials, and for nanotechnology in particular, information sharing on material characteristics by sellers and buyers, and sometimes also by regulators, is important and is facilitated by the development of appropriate material specifications. For a comprehensive exchange of information, it is essential to agree on the description of the material characteristics. However, many characteristics of nanomaterials cannot be determined using general and well-established measurement methods. This may become the cause for inconsistency in experimental results and induce confusion in commerce and technology transfer. Furthermore, the rapid discovery of new materials from nanotechnology increases the number of characteristics that need to be specified for an appropriate dissemination of information.
