Leather - Determination of distension and strength of surface (Ball burst method) (ISO 3379:2015)

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 3379:2015)

Die vorliegende Internationale Norm legt ein Prüfverfahren zur Bestimmung der Ausdehnung und Stärke der Narbung oder der zugerichteten Oberfläche fest. Dieses Verfahren gilt für alle flexiblen Lederarten und ist besonders zur Bestimmung der Aufzwickbarkeit von Lederarten für Schuhoberleder geeignet.

Cuir - Détermination de l'extension et de la résistance à la traction de la surface (méthode de la bille) (ISO 3379:2015)

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.

Usnje - Ugotavljanje razteznosti in trdnosti površine (metoda s kroglico) (ISO 3379:2015)

Ta mednarodni standard določa preskusno metodo za ugotavljanje razteznosti in trdnosti zrnatega usnja ali končne obdelane površine. Ta metoda se uporablja za vse prožno usnje in je še posebej primerna za ugotavljanje obstojnosti usnja za zgornje dele obutve.

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).
