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
With the development of society and the improvement of people’s living standards, the chemical
safety of footwear has widely gained attention. As more critical substance in footwear and footwear
components are needed, many chemical test methods for critical substances have been developed.
However, there lacks a unified sample preparation method for chemical tests. Due to the complex
materials and structures used in footwear and the different ways in which critical substances exist,
the sample taken from footwear is often not sufficiently homogeneous to give a representative test
specimen. It is thus very difficult to develop a single technique of sampling that can be used in all
circumstances. However, if every material in an article of footwear were tested, it would be a large
amount of work and yield a large test fee. As an example, see Table 1, a common article of footwear
can cut into over 10 kinds of test specimen when carrying out tests for one chemical. So, a sampling
method is needed urgently to provide general rules for preparation of samples, which can reduce and
even prevent the inconsistency of sampling procedures between different laboratories and which can
provide a guarantee for the stability of test results.
