Significance and Use
3.2.1 Terms and their related standard definitions in Section 4 are intended for use uniformly and consistently in all nanotechnology test methods, specifications, guides, and practices. The purpose of such use is to promote a clear understanding and interpretation of the standards in which they are used.
22.214.171.124 Terms and nomenclature are based on observed scientific phenomena and are descriptive, distinguishable, and have significant currency in the nanotechnology field as reflected in peer-reviewed articles and other objective sources. These terms and names should not disrupt accepted usage in other scientific and technological fields, and their preferred usage should follow accepted scientific syntax.
126.96.36.199 When incorporating a term or name from a related field, its underlying meaning is not redefined. Modifications are minimal and are done to elucidate scientific distinctions required by nanotechnology practitioners.
3.3.3 Each standard in which a term is used in a specially defined manner beyond the definitions in Section 3 should list the term and its description under the subheading, descriptions of terms.
3.3.4 Practice E1964, Section 13, are used to guide the contents of descriptions.
3.3.5 As nanotechnology is a rapidly developing field, it will be necessary to continually reassess the terms and definitions contained in this standard, for purposes of revision when necessary. The intent of the terms and definitions in this standard is to describe materials containing features between approximately 1 and 100 nm and to differentiate those properties different from properties found in either molecules or the bulk (interior) of larger, micron-sized systems.
1.1 Nanotechnology is an emerging field; this standard defines the novel terminology developed for its broad multi- and interdisciplinary activities. As the needs of this area develop, this standard will evolve accordingly. Its content may be referenced or adopted, or both, in whole or in part, as demanded by the needs of the individual user.
