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
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 types of natural substances have been used.

madder
common name for Rubia which is a genus of flowering plants in the Rubiaceae family
Note 1 to entry: Rubia is a genus of flowering plants in the Rubiaceae family. The genus and its best-known
species are commonly known as madder, e.g. Rubiatinctorum (common madder), Rubiaperegrina (wild madder),
and Rubiacordifolia (Indian madder). The plant's roots contain an anthraquinone compound called alizarin and
glycosides that gives red colour to the dyed textile. Alizarin is the major dye obtained from Rubiatinctorum and
may be got in very small amounts from the other species. Purpurin and its precursors are major dye compounds
obtained from the other tw
