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.
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 17232 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, the secretariat of which is
held by UNI. It was published as EN 13540. 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.
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.

1 Scope
This International Standard 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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 2418, Leather — Chemical, physical and mechanical and fastness tests — Sampling location
ISO 2419, Leather — Physical and mechanical tests — Sample preparation and conditioning
3 Method A — Lastometer method
3.1 Principle
A perforated test piece is distended by a specified amount. The surface is heated and any damage to the
patent finish is noted.
3.2 Apparatus
3.2.1 Test machine, including the parts described in 3.2.1.1 to 3.2.1.4.
3.2.1.1 Clamp, capable of holding the test piece around its edge leaving free a central circular area of
diameter 25,0 mm ± 0,1 mm. The design of its clamping system shall ensure that the test piece does not slip
under the test conditions and neither stretches nor compresses the central area as it is clamped. The
boundary between the free and clamped area shall be sharply defined.
3.2.1.2 Plunger, terminating in a steel ball of diameter 21,0 mm ± 0,1 mm.
3.2.1.3 Mechanism for thrusting the steel ball, without rotation against the test specimen.
3.2.1.4 Mechanism for monitoring the distension of the steel ball, (travel from zero) to an accuracy of
± 0,05 mm.
3.2.2 Press knife, conforming to the requirements of ISO 2419 for cutting test pieces of suitable
dimensions for the test ma
