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

Introduction
Cashmere is a high value speciality animal fibre, but cashmere and other animal wool fibres such as
sheep’s wool, yak, camel, etc. exhibit great similarities in their physical and chemical properties so that
their blends are difficult to distinguish from each other by both mechanical and chemical methods. In
addition, these fibres show similar scale structures. It is very difficult to accurately determine the fibre
content of such fibre blends by current testing means.
Research on the accurate identification of cashmere fibres has been a long undertaking. At present,
the most widely used and reliable identification techniques i
