The work of prep
22、aring International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in
23、liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task
24、of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other c
25、ircumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted f
26、or publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the commit
27、tee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at whi
28、ch time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

30、s reservedIntroduction As many authorities predict that applications of nanotechnologies will pervade all areas of life and will enable dramatic advances to be realized in all areas of communication, health, manufacturing, materials and knowledge-based technologies, there is an obvious need to provi
31、de industry and research with suitable tools to aid the development and application of those technologies. It is also essential that regulators and health and environmental protection agencies have available reliable measurement systems and evaluation protocols supported by well-founded and robust s
32、tandards. Often in the field of nanotechnologies, researchers with the aid of microscopes name materials inspired by the shape of objects found in everyday life although the physical size is much smaller. The prefix, nano-, is often added to denote the small size of the object. (The prefix nano-, is
33、 also used in S.I. units to indicate 109e.g. 1 nanometre = 109metre.) To create a unitary standard, this terminology and definitions document encompasses terms used in both nanosciences and nanotechnologies concerning particles at the nano-scale. Nano-object and other new terms are coined to allow d
34、evelopment of a rational hierarchical system of definitions. This hierarchy will allow systematic building of vocabulary and is contained in a larger hierarchy of terms under development for nanotechnologies. This document provides an up-to-date listing of terms and definitions relevant to the area.
35、 It forms one part of a projected multi-part terminology and definitions document covering the different aspects of nanotechnologies. It is intended to facilitate communications between organizations and individuals in industry and those who interact with them. This document is concerned with the de
36、finition of terminology and definitions for these small objects. These objects come in several shapes; the three basic shapes referred to in this document are illustrated in Figure 1: a) nanoparticle b) nanorod c) nanoplate Figure 1 Schematic diagrams showing some shapes for nano-objects There is a
37、hierarchical relationship between many of the different terms in the document. Some elements of this are shown in Figure 2 to illustrate some of the relationships that exist.

It is intended to facilitate comm
41、unications between organizations and individuals in industry and those who interact with them. 2 Core terms related to particles 2.1 nanoscale size range from approximately 1 nm to 100 nm NOTE 1 Properties that are not extrapolations from a larger size will typically, but not exclusively, be exhibit
42、ed in this size range. For such properties the size limits are considered approximate. NOTE 2 The lower limit in this definition (approximately 1 nm) is introduced to avoid single and small groups of atoms from being designated as nano-objects or elements of nanostructures, which might be implied by
43、 the absence of a lower limit. 2.2 nano-object material with one, two or three external dimensions in the nanoscale NOTE Generic term for all discrete nanoscale objects. 3 Terms concerning particles and assemblies of particles Nano-objects (for example nanoparticles, nanofibres, and nanoplates see C
44、lause 4), often occur in (large) groups, rather than isolated. For reasons of surface energy, such coexisting nano-objects are likely to interact. In the description of these interactions, the following terms are often used. The following terms are not restricted with respect to physical size and sh
45、ape. These terms are included for completeness and their importance at the nanoscale. 3.1 particle minute piece of matter with defined physical boundaries ISO 14644-6:2007, definition 2.102 NOTE 1 A physical boundary can also be described as an interface. NOTE 2 A particle can move as a unit. NOTE 3
46、 This general particle definition applies to nano-objects.

48、 forces, or simple physical entanglement. NOTE 2 Agglomerates are also termed secondary particles and the original source particles are termed primary particles. 3.3 aggregate particle comprising strongly bonded or fused particles where the resulting external surface area may be significantly smaller than the sum of calculated surface areas of the individual components NOTE 1 The forces holding an aggregate together are strong forces, for example covalent bonds, or those resulting from sintering or complex physical entanglement.
