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 document 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).

Introduction
Carbon fibre has drawn much attraction in various industries due to its high stiffness, specific strength
and anti-corrosion. These outstanding properties of carbon fibre enable the expansion of its application
from textile usage to mechanical parts used in automobile and aircraft industry, if carbon fibre is used
as a reinforced component in polymer matrix.
In order to accelerate the trend of productization using carbon fibre, there is a prerequisite that the
carbon content in the fibre should be evaluated quantitatively. In addition, it is difficult to issue a test
report because even an accredited test organization cannot provide a clear method of quantification.
X-ray photoelectron spectroscopy is one of the measurement method suitable for analysis of chemical
components with quality and quantity. However, its detecting area is too small to cover the entire fibre.
This document aims to quantifz carbon content in textiles and textile products including PAN-based
carbon fibre using elemental analyser (EA) and gas chromatography (GC), successively. Furthermore,
this method can also analyse the contents of H and N, simultaneously.
