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 of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
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 document was prepared by the Physical Test Commission of the International Union of Leather
Technologists and Chemists Societies (IUP Commission, IULTCS), in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, in accordance with
the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
The Chemical and Fastness Test Commissions were consulted in the preparation of this document. The
locations of the test specimens are identical to those given in IUP 2 published in J. Soc. Leather Trades
Chemists, 42, pp. 382–385, 1958 and IUC 2 published in J. Soc. Leather Trades Chemists, 49, pp. 6–8, 1965.
IUP 2 was declared an official method in 1959 and IUC 2 in 1965. Updated versions were published
in J. Soc. Leather Tech. Chem., 82, p. 194, 1998 and further revisions were published in J. Soc. Leather
Tech. Chem., 84, p. 303, 2000 and reconfirmed as official methods in March 2001. This document differs
slightly in the text and includes tolerances for measurements but the locations of the test specimens are
identical.
This fourth edition cancels and replaces the third edition (ISO 2418:2017), which has been technically
revised.
The main changes are as follows:
— title has been revised to more correctly explain the purpose of this document;
— entries 3.1 and 3.2 have been added and the text throughout the document has been revised to use
the words “specimen” and “test piece” where appropriate instead of “sample” and “sampling”;
