Nanomanufacturing - Material specifications - Part 2-1: Single-wall carbon nanotubes - Blank detail specification
IEC/PAS 62565-2-1:2011(E) establishes a blank detail specification for the essential electrical properties and certain other common characteristics including dimensional, structural and mechanical properties of single-wall carbon nanotubes. It provides a standardized format for detail specifications characterising essential basic properties of single-wall nanotubes and recommends measurement methods. Single-wall carbon nanotubes with a chemical modification, dispersed into a solvent or grown on a substrate are included. A PAS is a technical specification not fulfilling the requirements for a standard, but made available to the public. Following publication of this PAS, which is a pre-standard publication, the technical committee concerned may transform it into an International Standard.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

available to the public.

INTRODUCTION
This Publicly Available Specification is intended to provide guidance on how to list, illustrate
and define various characteristics of single-wall carbon nanotubes (SWCNTs) for industrial
use in electronic products, and how to incorporate these into a bilateral detail specification
between vendor and user.
One particular point of interest is the fact that there are different modifications of carbon
nanotubes. Subtle differences in the physical structure lead to marked differences in
electrical, optical and chemical properties; therefore these characteristics need special
attention.
To permit common processing equipment and common unit processes with predictable and
reproducible results to be used in multiple fabrication lines, it is essential for the carbon
nanotubes characteristics to be described and assessed in a standardized manner and to
standardize the methods for quality control of the manufacturing processes.
To enable low-cost mass production (or production of pure fractions), a reliable, affordable
means of preparing one type of carbon nanotubes (e.g. single-wall semiconducting carbon
nanotubes, with a certain specified length) is necessary. To facilitate a reliable source of
carbon nanotubes with tailored properties (length, diameter, purity, chirality, conduction type),
it is necessary to specify the characteristics in a standardized way, stating the specification
limits and the characterization methods to prove conformance. This does not only reduce
transaction costs, but eliminates a major source of error, as explained below.
Accurately measuring and characterising the quality of nanotube-containing materials and the
dispersion of nanotubes in liquids or polymers, are both considered crucial for the continued
growth of applications incorporating single-wall carbon nanotubes. Significant differences in
both methodology and interpretation continue to exist from one measurement laboratory to
another. For this reason, comparison and specification of the quality of CNT materials is
extremely difficult. While progress in these measurements is being been made, significant
improvements are still needed to accurately measure and characterise the quality of carbon
nanotube-containing materials and the protocol for doing so (e.g. how to describe / specify the
characteristics relevant for the quality of the final nano-enabled product).
Furthermore, the development of reference materials is as important as improvements to
measurement / characterization techniques. In addition, it is stressed that for any of the
analysis methods, it is mandatory to specify the sample preparation method, sample size and
the sampling method.
Experiences with this PAS should be reported to the Secretariat of IEC Technical Committee
113 to provide improvements for the future IEC 62565 International Standards under
development in IEC/TC 113.
