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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
ISO 17070 was prepared by the Chemical Test Commission of the International Union of Leather
Technologists and Chemists Societies (IUC Commission, IULTCS) in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of
which is held by UNI, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to
further the advancement of leather science and technology. IULTCS has three Commissions, which are
responsible for establishing international methods for the sampling and testing of leather. ISO recognizes
IULTCS as an international standardizing body for the preparation of test methods for leather.
This second edition of ISO 17070 cancels and replaces the first edition (ISO 17070:2006), which has been
technically revised. ISO 17070:2006 previously replaced CEN/TS 14494.
The following changes have been made:
— the additional chlorinated phenol substances tetrachlorophenol-, trichlorophenol-, dichlorophenol-,
and monochlorophenol-isomers are included;
— a new Clause 3 has been inserted to list the chlorophenol abbreviations;
— the examples of chromatographic conditions, previously in 7.4, have been moved to a new Annex A
(the previous Annex A becomes Annex B).
Annexes A and B are informative.

Introduction
This International Standard describes a procedure where the chlorinated phenols (CP) are acetylated
before the chromatographic detection and the amount of the detected chlorinated phenyl acetate is
quantified via an internal standard correction.
