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

Introduction
There is no doubt that dyeing plays the most important role in expressing the colour of clothes. Until
the invention of synthetic dyes capable of expressing diverse colours, materials obtained from nature
to dye fabric have been used. Typically, colourants were obtained from plants or various materials were
extracted from minerals or insects. When dyeing fabrics using materials derived from these natural
substances, it becomes necessary to identify which substances the colourant was derived from. In other
words, there has been a demand to confirm whether a fabric is dyed using a natural substance.
A test method is developed to identify which type of natural substances have been used.
