Leather - Determination of distension and strength of surface (Ball burst method) (ISO/FDIS 3379:2024)

ISO 3379:2015 specifies a test method for the determination of distension and strength of the leather grain or finished surface. This method is applicable to all flexible leathers and it is particularly suitable to determine the lastability of leathers for footwear uppers.

Leder - Bestimmung der Narbendehnfähigkeit und ‑bruchkraft (Lastometer-Methode) (ISO/FDIS 3379:2024)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Dehnfähigkeit und der Dehnbruchkraft des Narbens oder einer zugerichteten Oberfläche fest. Dieses Verfahren ist anwendbar auf alle flexiblen Lederarten und ist besonders zur Bestimmung der Aufzwickbarkeit von Schuhoberledern geeignet.

Cuir - Détermination de l'extension et de la résistance à la traction de la surface (méthode de la bille) (ISO/FDIS 3379:2024)

ISO 3379:2015 spécifie une méthode de détermination de l'extension et de la résistance à la traction de la fleur d'un cuir ou d'une surface finie. Cette méthode est applicable à tous les cuirs souples, et elle est particulièrement adaptée à la détermination de l'aptitude au montage des cuirs pour tiges d'articles chaussants.

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 (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 3379 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, 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 third edition cancels and replaces the second edition (ISO 3379:2015), which has been technically
updated as follows:
— the terminology and references are modified so it is in line with ISO 2418:2023;
— clause 6 has been re-arranged to make it easier to follow.
