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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a technical
committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee
casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further
three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed,
it is reviewed again after a further three years, at which time it must either be transformed into an International
Standard or be withdrawn.
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.
ISO/TS 16179 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 309, Footwear, in collaboration with ISO Technical Committee ISO/TC 216, Footwear, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

TECHNICAL SPECIFICATION ISO/TS 16179:2012(E)
Footwear — Critical substances potentially present in footwear
and footwear components — Determination of organotin
compounds in footwear materials
1 Scope
This Technical Specification specifies a test method for determining the presence of organotin compounds.
This test method is applicable to all types of footwear materials.
NOTE ISO/TR 16178 defines which materials are concerned by this determination.
2 Normative references
ISO 3696, Water for analytical laboratory use — Specification and test methods
3 Principle
The organotin substances are extracted from the footwear material with a methanol-ethanol mixture, in a
medium-strength acidic condition, using tropolone as a complexant agent.
The polar and high-boiling organotin is then converted to the corresponding volatile tetra-alkyl derivative, by
reaction with sodium tetraethylborate, NaB(Et) . Finally, it is detected by a gas chromatograph fitted with a
4
mass selective detector (GC-MS).
Table 1 indicates the list of target compounds which can be analysed with this Technical Specification.
