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
This document covers a test method for the determination of the certain organic solvents in footwear
products.
Industrial organic solvents are often used in or ingredients of adhesive, treating agents and coating
agents for footwear.
Some organic solvents have been proved to be toxic. Harmful solvents left in footwear materials may
penetrate into human body through contact with human skin during wearing and through human
breath after being released from footwear, which harms the health of consumers. Both glycol ethers
solvents and amide solvents will form highly toxic compounds after metabolism in the body, which
cause permanent damage to the blood circuit and the nervous system. Long-term exposure to high
concentration may cause cancer. In addition, ethylene glycol ether solvents may cause permanent
damage to the reproductive system of the female.
Due to this potential effect, the listed organic solvents are based on those which have been restricted in
[1]
some regulations (e.g. in the European Union (regulation (EU) No 1907/2006 and U.S. Environmental
Protection Agency).

WARNING — This document calls for the use of substances and/or procedures that might be
injurious to health if adequate precautions are not taken. It refers only to technical suitability
and does not absolve the user from legal obligations relating to health and safety at any stage.
It has been assumed in the drafting of this document that the execution of its provisions is
entrusted to appropriately qualified and experienced operators.
1 Scope
This document specifies a method for the quantification of certain organic solvents (see Annex A)
residues in footwear materials with gas chromatography-mass spectrometry (GC-MS).
This document is applicable to footwear materials where there is a risk of the presence of certain
solvents residues (for example, solvents present in glues, leather finishing, coated textiles, etc…).
NOTE ISO/TR 16178 describes which materials are concerned by this determination.
