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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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.
This document was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 289, Leather, 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).
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 cancels and replaces the first edition (ISO 5403-2:2011), which has been technically
revised.
The main changes are as follows:
— update to the latest versions of ISO 2418 and ISO 2419;
— revision of the technical wording.
A list of all parts in the ISO 5403 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Leather — Determination of water resistance of flexible
leather —
Part 2:
Repeated angular compression (Maeser)
1 Scope
This part of ISO 5403 specifies a method for determining the dynamic water resistance of leather by
means of repeated angular compression. It is applicable to all flexible leathers but is particularly suitable
for leathers intended for footwear applications. It uses a Maeser-type machine and includes an option for
electronic detection.

4 Principle
A square test specimen is folded and secured in two V-shaped clamps which have closed ends so as to form a
trough. The trough is then immersed in water and the clamp at one end oscillates at a constant speed so that
the specimen is repeatedly flexed. The test is stopped at t
