    17、 bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bodyinterested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental a

    18、nd non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closelywith 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,

    19、 Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted 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 casti

    20、ng a vote. In other circumstances, particularly when there is an urgent market requirement forsuch documents, a technical committee may decide to publish other types of document: an ISOPubliclyAvailable Specification (ISO/PAS) represents anagreement between technical experts inan ISO working group a

    21、nd is accepted for 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 technicalcommittee and is accepted for publication if it is approved by 2/3 of the member

    22、s of the committee casting a vote. An ISO/PAS or ISO/TSis reviewed after three years in order todecide whether it willbe confirmed for afurther three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS isconfirmed, it is reviewed again after a further three yea

    23、rs, at which time it must either be transformed into an International Standard or be withdrawn.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.

    26、nufacturing, materials andknowledge-based technologies, there is an obvious need to provide industryand research with suitable toolsto aid the development and application of those technologies. It is also essential that regulators and health and environmental protection agencies have available relia

    27、ble measurement systems and evaluation protocols supported by well-founded and robust standards.Often in the field of nanotechnologies, researcherswith the aid of microscopes namematerials inspired by theshape of objects found in everydaylife although the physical size is much smaller. The prefix, n

    28、ano-, is oftenadded to denote the small size of the object. (The prefix nano-, is 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 pa

    29、rticles at the nano-scale. Nano-object and other new terms are coined to allow development of a rational hierarchical system of definitions. This hierarchy will allowsystematic building of vocabularyand is contained in a larger hierarchy of terms under development fornanotechnologies. This document

    30、provides an up-to-date listing of terms and definitions relevant to the area. Itforms one part of a projected multi-part terminology and definitions document covering the different aspects ofnanotechnologies. It is intended to facilitate communications between organizations and individuals in indust

    31、ryand those who interact with them. This document is concerned with the definition of terminologyand 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) nanofibrec) nanoplateFig

It isintended to facilitate communications between organizations and individuals in industry and those who interactwith them. 2 Core terms related to particles 2.1 nanoscale

    35、size range from approximately 1 nm to 100 nmNOTE 1Properties that are not extrapolations from a larger size will typically, but not exclusively,be exhibited in thissize range. For such properties the size limits are considered approximate. NOTE 2The lower limit in this definition (approximately 1 nm

    36、) is introduced to avoid single and small groups of atomsfrom being designatedas nano-objectsor elements of nanostructures, which might be implied by the absence of a lower limit. 2.2 nano-objectmaterial with one, two or three external dimensions in the nanoscaleNOTE Generic term for all discrete na

    37、noscale objects. 3 Terms concerning particles and assemblies of particles Nano-objects (for example nanoparticles, nanofibres, and nanoplates see Clause 4), often occur in (large)groups, rather than isolated. For reasons of surface energy, such coexisting nano-objects are likely to interact.In the d

    38、escriptionof these interactions, the following terms are often used. The following terms are not restricted with respect to physical size and shape. These terms are included for completeness and theirimportance at the nanoscale. 3.1 particle minute piece of matter withdefined physical boundariesISO
