The ISO 4217 standard includes a crude mechanism
ISO/TS 80004 which addresses graphene and quantum phenomena. ISO/TR 18401 provides plain language explanations of selected terms from the ISO 80004 series. ISO/TS 80004-7:2011 provides consistent and unambiguous use of terms for healthcare professionals, manufacturers, consumers, technologists, patent agents, regulators, NGOs, and researchers, etc. ISO/TS 80004 The ISO/TS 80004 series of standards, from the International Organization for Standardization, describe vocabulary for nanotechnology and its applications. These were largely motivated by health, safety and environment concerns, many of them originally elaborated by Eric Drexler in his 1985 Engines of Creation and echoed in more recent research. The ISO standards simply describe vocabulary or
