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

on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction

With the development of society and the improvement of people’s living standards, the chemical safety

of footwear has widely gained attention. More critical substance in footwear and footwear components

are required, so many chemical test methods for critical substance have correspondingly 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 that critical substances exist, the

sample taken from footwear often can’t be mixed well to give a representative test piece, so it is very

difficult to develop a single technique of sampling that will serve in all circumstances. But if every

material in an article of footwear were to be tested, it would be a large amount of work and a large test

fee. As an example, in Annex A, 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 sampling

procedure in different laboratories and can provide a guarantee for the stability of test results.

This standard intends to specify terms and definitions, instruction of procedures and some special

examples etc., to give a rough specification for sampling shoes when carrying out chemical tests, and

can be acceptable in meeting the common types of problem encountered in sampling for the assessment

of footwear critical substance content.

The sampling procedures described are designed to allow concurrent chemical testing for footwear.
