Geosynthetics - Wide-width tensile test (ISO 10319:2008)
This International Standard describes an index test method for the determination of the tensile properties of geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics, including woven geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles and felts. The method is also applicable to geogrids and similar open-structure geotextiles, but specimen dimensions might need to be altered. This test is not applicable to polymeric or bituminous geosynthetic barriers, while it is applicable to clay geosynthetic barriers. The tensile test method covers the measurement of load elongation characteristics and includes procedures for the calculation of secant stiffness, maximum load per unit width and strain at maximum load. Singular points on the load-extension curve are also indicated. Procedures for measuring the tensile properties of both conditioned and wet specimens are included in this International Standard.
Geotextilien - Zugversuch am breiten Streifen (ISO 10319:2008)
Diese Internationale Norm beschreibt ein Indexprüfverfahren für die Bestimmung der Zugfestig¬keits¬eigenschaften von Geokunststoffen unter Verwendung eines breiten Streifens. Das Verfahren ist auf die meisten Geokunststoffe, einschließlich gewebten Geokunststoffen, Geovliesstoffen, Geoverbundstoffen, Geomaschenwaren und Filzen anwendbar. Das Verfahren ist auch auf Geogitter und ähnliche offen strukturierte Geotextilien anwendbar, jedoch müssen im Bedarfsfall die Probenabmessungen geändert werden. Dieses Verfahren gilt nicht für geosynthetische Kunststoff- oder Bitumendichtungsbahnen, während es für geosynthetische Tondichtungsbahnen anwendbar ist.
Das Zugprüfverfahren umfasst die Messung der Kraft-Dehnungseigenschaften und schließt Verfahren zur Be¬rechnung der Sekantensteifheit, der Höchstkraft je Breiteneinheit und der Dehnung bei der Höchstzugkraft ein. Einzelne Punkte der Kraft-Dehnungskurve sind ebenfalls angegeben.
Verfahren zur Messung der Zugfestigkeitseigenschaften sowohl von an das Normalklima angeglichenen Proben als auch von Nassproben sind in dieser Internationalen Norm enthalten.
Géosynthétiques - Essai de traction des bandes larges (ISO 10319:2008)
L'ISO 10319:2008 décrit une méthode d'essai de référence pour la détermination des propriétés mécaniques en traction des géosynthétiques à l'aide d'une bande de grande largeur. La méthode est applicable à la plupart des géosynthétiques, incluant les géotextiles tissés, les non-tissés, les géocomposites, les géotextiles maillés et les feutres. La méthode s'applique également aux géogrilles et ou produits similaires tels que géotextiles à structure ouverte mais il peut s'avérer nécessaire de modifier les dimensions de l'éprouvette. Cet essai n'est pas applicable aux géomembranes alors qu'il est applicable aux géosynthétiques bentonitiques.
La méthode d'essai par traction couvre le mesurage des caractéristiques de force et de déformation et comprend les modes de calcul de la raideur sécante, de la force maximale par unité de largeur et de la déformation à la force maximale. Une mention est faite également des points singuliers sur la courbe force/déformation.
Des modes opératoires de mesure des propriétés mécaniques en traction d'éprouvettes conditionnées et d'éprouvettes mouillées figurent également dans l'ISO 10319:2008.

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 10319 was prepared by Technical Committee ISO/TC 221, Geosynthetics.
This second edition cancels and replaces the first edition (ISO 10319:1993), which has been technically
revised.

Geosynthetics — Wide-width tensile test
1 Scope
This International Standard describes an index test method for the determination of the tensile properties of
geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics, including woven
geotextiles, nonwoven geotextiles, geocomposites, knitted geotextiles and felts. The method is also applicable
to geogrids and similar open-structure geotextiles, but specimen dimensions might need to be altered. This
test is not applicable to polymeric or bituminous geosynthetic barriers, while it is applicable to clay
geosynthetic barriers.
The tensile test method covers the measurement of load elongation characteristics and includes procedures
for the calculation of secant stiffness, maximum load per unit width and strain at maximum load. Singular
points on the load-extension curve are also indicated.
Procedures for measuring the tensile properties of both conditioned and wet specimens are included in this
International Standard.

4 Principle
A test specimen is held across its entire width in a set of clamps or jaws (see Figure 2) of a tensile testing
machine operated at a constant speed, and a longitudinal force is applied to the test specimen until the
specimen ruptures. The tensile properties of the test specimen are calculated from machine scales, dials,
autographic recording charts, or an interfaced computer. A constant test speed is selected so as to give a
strain rate of (20 ± 5) % per minute in the gauge length of the specimen.
The basic distinction between the current method and other methods for measuring tensile properties of
fabrics is the width of the specimen. In the current method, the width is greater than the length of the
specimen, as some geosynthetics have a tendency to contract (neck down) under load in the gauge length
area. The greater width reduces the contraction effect of such fabrics and provides a relationship closer to the
expected fabric behaviour in the field, as well as a standard for comparison of geosynthetics.
The test uses test specimens 200 mm wide and 100 mm long (see 6.3.3 for details on th
