The work of preparing International Standards is normally carried out through ISO technical committees. Each memb
18、er 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 liaison with ISO, also take part in the work. ISO collaborates closely with the International Ele
19、ctrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types
20、of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

23、 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
24、 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
25、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.In order to address this need, a systematic arrangement of characteristics has been carried
26、 out across different fields of application specific to each nano-object by identifying a list of fundamental characteristics commonly used in these circumstances and by developing tailor-made technical specifications for the list, as seen in ISO/TS 11931 and ISO/TS 11937.Another approach that was f
27、ollowed for ISO/TS 12805 resulted in the development of a list of characteristics applicable to specifying nano-objects that are useful to the wider community of users of information on nano-objects.To increase the reach of outcomes from these efforts, members of ISO/TC 229 have discussed and planne
28、d the systematic development of an ISO technical specification for defining a list of fundamental characteristics that are widely applicable to a broad range of nano-objects. This Technical Specification is intended to define the list of fundamental characteristics universally for nanoparticles in p
29、owder form, which covers a very broad range of nano-objects.In order to develop a common understanding among sellers, buyers, and regulators, this Technical Specification uses the chemical composition, crystal structure, particle size, and surface area as fundamental measures for characterizing nano
30、-objects from a chemical, physical, and surface scientific point of view that is of significant interest to users of the nano-objects. However, since measurement procedures used for determining the characteristics of nano-objects often rely on various idealized assumptions, the resulting characteris
31、tics of nano-objects with identical name may not guarantee the equivalence of measured results. This issue can be addressed by adopting well-recognized measurement methods that can provide reliable measurement results.The measurement methods adopted in this Technical Specification are well known in
32、the industry. Instruments used for measurement and data processing software are well developed and provide reliable measurement results when operated under a valid quality system.The description of measurement methods is limited in this Technical Specification to important supplementary notices. For
33、 basic information about applying the methods, it is assumed that operating instructions are provided with any instruments, appropriate data processing software is available, and analysis has the required technical skills. The methods are applicable to situations where procedures are subcontracted t
34、o independent test laboratories. Since quantitative criteria concerning characteristics depend on the specific intentions among users, they are not described in this Technical Specification. These criteria are subject to agreement between users of this Technical Specification, namely, sellers, buyer
35、s, and regulators of nanoparticles in powder form.Nanotechnology is a rapidly growing and evolving field. Users of this Technical Specification should maintain familiarity with the legislative environment and latest developments in human and environmental health and safety regarding nanotechnology.I
36、f the seller or the buyer wishes to assess the environmental, safety, or health risks of the material, they may refer to ISO/TR 12885:2008 for further guidance. It has been assumed in the preparation of this Technical Specification that the execution of its provisions will be entrusted to appropriat
37、ely qualified and experienced people.
