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).

Introduction
Currently, contact-type (1) and noncontact-type thermal conductivity method (2) are used to measure
the thermal conductivity. The contact-type method exhibits measurement non-uniformity in the
carbon fibre thickness direction to unable uniform sampling, and the error occurrence rate is known to
be high. Also, the noncontact-type method, fibre porosity and tow gap can create lower accuracy, and
the error occurrence rate is similarly high. Therefore, this document is made to provide a quantitative
method for the measurement of carbon fibre thermal conductivity, using a thermal imaging camera,
that will alleviate problems observed in prior described methods.

Carbon fibres — Determination of polyacrylonitrile-based
(PAN-based) carbon fibre tow characteristics — Heat
transfer parameter
1 Scope
This document specifies a method using a thermal imaging camera for measuring the heat transfer
parameter of PAN-based 12 K carbon fibre tow with a filament diameter of 7 µm. This document is
applicable to both sized and unsized carbon fibres.
NOTE At the time of publication, the experience is on 12 K tow. Other tows will be included when the
experience becomes available.
