Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing 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 liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical 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 of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committees responsible for this document are ISO/TC 229, Nanotechnologies and Technical
Committee IEC/TC 113, Nanotechnology standardization for electrical and electronic products and systems.
The draft was circulated for voting to the national bodies of both ISO and IEC.
This first edition of ISO/TS 80004-2 cancels and replaces ISO/TS 27687:2008, which has been
technically revised.
Documents in the 80000 to 89999 range of reference numbers are developed by collaboration

Introduction
It is predicted that applications of nanotechnologies may pervade all areas of life. In the areas of
communication, health, manufacturing, materials and knowledge-based technologies, there is a need to
provide industry and research with standardized vocabulary and nomenclature to aid the responsible
development and application of the technologies. It is also essential that regulators such as health and
environmental protection agencies have reliable measurement systems supported by well-founded and
robust standards.
Often in the field of nanotechnologies, naming of materials seen on microscopic images is 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 also used in SI units to indicate
−9 −9
10 e.g. 1 nanometre = 10 metre.). Thus, the term “nanoscale” (2.1) has been defined to denote the
length interval approximately from 1 nm to 100 nm.
To create a unitary vocabulary, this part of ISO 80004 encompasses terms used concerning particles
with nanoscale dimensions. The terms in this part of ISO 80004 form part of a larger hierarchy of
terms under development for nanotechnologies. These terms are intended to facilitate communications
between organizations and individuals in industry and those who interact with them.
Objects with one or more external dimensions in the nanoscale can have properties that make them
key components of materials and systems resulting in improved performance over their conventional
counterparts. These nano-objects (2.2) often have properties that are not simple extrapolations of
the properties of their larger form, with these novel properties called emerging, discontinuous or
transformative properties.
The size and shape of nano-objects are often intrinsic to their function, so the description and
measurement of their size and shape are important and must be considered carefully. The three most
basic shapes referred to in this part of ISO 80004 are illustrated in Figure 1. These three simple shapes
represent the main classes of structural dimensionality to help categorize nano-objects. Some other
common shapes are defined in this part of ISO 80004, but a large number of different shapes are possible.
A number of other parameters in addition to size and shape are also intrinsic to the function and phenomena
exhibited by nano-objects. These parameters include composition, morphology, crystalline structure, and
surface features, which can all have a major influence on the key nanoscale phenomena exhibited by nano-
objects. Such phenomena include magnetic, optical, catalytic, electronic, and other properties.

A particular issue concerns nano-objects where one or more external dimensions are larger than the
nanoscale. Potential confusion can occur when one of these dimensions greatly exceeds the nanoscale.
For example, carbon nanotubes can have overall lengths in the millimetre range and are still nano-

is to consider the size or shape at which the health risk from inhalation
