Geosynthetics - Determination of compression behaviour - Part 1: Compressive creep properties (ISO 25619-1:2021)
This document specifies index test methods for determining the compressive creep properties of geosynthetic products. The test specimens are subjected either to normal compressive loading or to a combination of normal compressive loading and shear loading.
The test method with a normal load only (see Clause 5) is the standard method.
The test method in which combined normal and shear loads are applied (see Clause 6) is intended for products that are sensitive to shear failure, i.e. which have a columnar or cuspated structure.
The tests are carried out on dry specimens or on specimens immersed in water. The test is intended to be carried out with the specimen immersed in water when any part of the geosynthetic product contains a hydrophilic polymer.
Geokunststoffe - Bestimmung des Druckverhaltens - Teil 1: Eigenschaften des Druckkriechens (ISO 25619-1:2021)
Dieses Dokument legt Index Prüfverfahren zur Bestimmung der Eigenschaften des Druckkriechens von geosynthetischen Produkten fest. Die Messproben werden entweder einer normalen Druckbeanspruchung oder einer Kombination von normaler Druck und Scherbeanspruchung ausgesetzt.
Das Prüfverfahren nur mit normaler Druckbeanspruchung (siehe Abschnitt 5) ist das Standardverfahren.
Das Prüfverfahren, bei dem kombinierte Druck und Scherkräfte angewandt werden (siehe Abschnitt 6), ist für Produkte vorgesehen, die gegen Scherbruch anfällig sind, d. h. Produkte mit einer säulenartigen oder kegel oder pyramidenförmigen Struktur.
Die Prüfungen werden an trockenen oder in Wasser eingetauchten Messproben durchgeführt. Die Durchführung der Prüfung in Wasser eingetauchter Messproben ist dafür vorgesehen, wenn irgendein Teil des Geokunststoff Produktes ein hydrophiles Polymer enthält.
Géosynthétiques - Détermination du comportement en compression - Partie 1: Propriétés de fluage en compression (ISO 25619-1:2021)
Le présent document décrit des méthodes d'essai de référence permettant de déterminer les propriétés de fluage en compression des produits géosynthétiques. Les éprouvettes sont soumises soit à une charge de compression normale, soit à une charge de compression normale et à une charge de cisaillement simultanément.
La méthode d'essai avec application d'une charge normale uniquement (voir l'Article 5) est la méthode normalisée.
La méthode d'essai avec application simultanée de la charge normale et de la charge de cisaillement (voir l'Article 6) est destinée aux produits sensibles à la rupture en cisaillement, à savoir les structures en colonnes ou cupsidées.
Les essais sont effectués sur des éprouvettes sèches ou immergées dans l'eau. L'essai est destiné à être réalisé avec des éprouvettes immergées dans l'eau lorsqu'une quelconque partie du produit géosynthétique contient un polymère hydrophile.

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.

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/

This document was prepared by Technical Committee ISO/TC 221, Geosynthetics, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 189, Geosynthetics,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 25619-1:2008) which has been technically
revised.
The main changes compared to the previous edition are as follows:
— normative references have been updated;
— dimension and shape of the specimen for different types of geosynthetics have been introduced;
— calculation of the correct area for structure in which loading is resisted at defined points or at
defined lines have been introduced;
— the drawing of a test apparatus for compressive shear test that was not described in the test has
been deleted.
