Leather - Physical and mechanical tests - Determination of heat resistance of patent leather (ISO 17232:2017)
ISO 17232:2017 specifies two methods for determining the heat resistance of patent leather.
Method A makes use of a modified lastometer, while Method B uses the "Zwik" apparatus. Both methods are applicable to patent leathers for all end uses.

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 World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www . i so .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.
ISO 17232 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 289, Leather, the secretariat of which is held by UNI, in collaboration with the Physical
Test Commission of the International Union of Leather Technologists and Chemists Societies (IUP
Commission, IULTCS), in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
It is based on IUP 38 published in J. Soc. Leather Tech. Chem., 84 (7), p. 403, (2000), and declared an
official method of the IULTCS in March 2001.
This second edition cancels and replaces the first edition (ISO 17232:2006), which has been technically
revised with the following changes:
— the test conditions in 4.4.4 have been clarified;
— a reference to specific standard conditions in 4.5 e) and 5.5 d) has been removed.
