Geosynthetics - Tensile test for joints/seams by wide-width strip method (ISO 10321:2008)

ISO 10321:2008 specifies an index test method for determination of the tensile properties of joints and seams in geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics. It is also applicable to geogrids, but the specimen dimensions may need to be altered. This test is not applicable to polymeric or bituminous geosynthetic barriers.
The method specified in ISO 10321:2008 quantifies the tensile strength of a joint or seam between geosynthetics. It can provide data to indicate the joint or seam tensile strength which can be achieved.
Procedures for measuring the tensile properties of both conditioned and wet specimens are included.

Geokunststoffe - Zugprüfung von Verbindungen/Nähten am breiten Streifen (ISO 10321:2008)

Diese Internationale Norm legt ein Indexprüfverfahren zur Bestimmung der Zugfestigkeitseigenschaften von Verbindungen und Nähten in Geokunststoffen unter Verwendung eines breiten Streifens fest. Das Verfahren ist auf die meisten Geokunststoffe anwendbar. Es ist auch auf Geogitter anwendbar, jedoch müssen im Bedarfsfall die Probenabmessungen geändert werden. Dieses Verfahren gilt nicht für geosynthetische Kunststoffdichtungsbahnen oder geosynthetische Bitumendichtungsbahnen.
Dieses Verfahren bestimmt quantitativ die Zugfestigkeit einer Verbindung oder einer Naht zwischen Geokunststoffen. Es kann Daten liefern, um die Verbindungs  oder Nahtzugfestigkeit nachzuweisen, die erreicht werden kann.
Die Wirksamkeit der Verbindung oder Naht kann durch Vergleich zwischen der Zugfestigkeit der Verbindung/Naht mit der Zugfestigkeit des fugenlosen  Materials nach ISO 10319 berechnet werden.
Verfahren zur Messung der Zugfestigkeitseigenschaften von an das Normalklima angeglichenen Proben und von nassen Proben sind enthalten.
Für bestimmte Geokunststoffe, z. B. für schwere Geokunststoffe, Netze oder Geokunststoffe aus Glasfasern, können technische Änderungen des Prüfverfahrens notwendig sein, um zu verhindern, dass das Probenmaterial in den Einspannklemmen rutscht oder dadurch beschädigt wird, dass es in den Klemmen gehalten wird.
Die Grundprüfung verwendet für alle Verbindungen oder Nähte von Geokunststoffen Messproben von 200 mm Breite mit einer Verbindungs  oder Nahtzugabe von 25 mm auf jeder Seite, um eine Verbindungs  oder Nahtstabilität während der Prüfung zu erreichen (siehe Bild 1).

Géosynthétiques - Essai de traction des joints/coutures par la méthode de la bande large (ISO 10321:2008)

L'ISO 10321:2008 spécifie une méthode d'essai de référence pour la détermination des propriétés mécaniques en traction des joints et coutures des géosynthétiques, à l'aide d'une bande de grande largeur. La méthode est applicable à la plupart des géosynthétiques. Elle s'applique également aux géogrilles, mais il peut s'avérer nécessaire de modifier les dimensions de l'éprouvette. Cet essai n'est pas applicable aux géomembranes et géosynthétiques bentonitiques.
La méthode décrite dans l'ISO 10321:2008 quantifie la résistance à la traction d'un joint ou d'une couture entre géosynthétiques. Elle peut fournir des données indiquant la résistance à la traction que peut atteindre un joint ou une couture.
Sont inclus des modes opératoires pour la mesure des propriétés mécaniques en traction d'éprouvettes conditionnées et d'éprouvettes humides.

Overview

EN ISO 10321:2008 - Geosynthetics - Tensile test for joints/seams by wide‑width strip method (ISO 10321:2008) defines an index laboratory method to measure the tensile properties of joints and seams in geosynthetics using a wide‑width strip specimen. The standard applies to most geosynthetics (including geogrids with modified specimen dimensions) but excludes polymeric or bituminous geosynthetic barriers. Results quantify joint/seam tensile strength and allow calculation of joint or seam efficiency versus the unjointed material (referencing ISO 10319).

Key topics and technical requirements

• Specimen geometry: nominal specimen width 200 mm; initial jaw separation = 100 mm + seam/joint width; 25 mm extensions either side of the seam for stability.
• Number of tests: cut and test at least five specimens (plus five additional if wet testing required).
• Conditioning:
  • Standard atmosphere per ISO 554: 20 °C ± 2 °C and 65 % RH ± 5 % RH.
  • Wet conditioning: immersion in water at 20 °C ± 2 °C for at least 24 hours; up to 0.05 % non‑ionic wetting agent permitted.
• Test machine and clamps:
  • Constant rate of extension tensile machine complying with ISO 7500‑1, Class 2 or higher.
  • Jaw faces at least 200 mm wide; use wedge jaws, compressive block jaws or capstan grips to limit slippage and damage.
• Test parameters:
  • Strain rate that produces (20 ± 5) %/min in gauge length.
  • Record maximum force to 0.01 kN accuracy.
• Results & reporting:
  • Report maximum joint/seam strength (kN/m), failure mode (material break, sewing thread break, joint failure, slippage, etc.), and joint/seam efficiency (%) relative to tensile strength from ISO 10319.
  • Include conditioning details, specimen orientation and failure observations.

Applications and users

EN ISO 10321:2008 is used for:

• Product performance verification by manufacturers of geotextiles, geogrids and sewn or welded geosynthetics.
• Independent testing laboratories performing QA/QC and type testing.
• Designers, specifiers and contractors needing reliable joint/seam strength data for containment, drainage, reinforcement and lining systems.
• Regulatory bodies and project engineers requiring documented seam performance for safety and compliance.

Practical benefits: enables comparison of seam methods (sewing, welding, mechanical joints), informs construction tolerances, and supports specification of joint efficiency in design.

ISO 10321:2008(E) iv © ISO 2008 – All rights reserved 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 10321 was prepared by Technical Committee ISO/TC 221, Geosynthetics. This second edition cancels and replaces the first edition (ISO 13021:1992), which has been technically revised.

INTERNATIONAL STANDARD ISO 10321:2008(E) © ISO 2008 – All rights reserved 1Geosynthetics — Tensile test for joints/seams by wide-width strip method 1 Scope This International Standard specifies an index test method for determination of the tensile properties of joints and seams in geosynthetics, using a wide-width strip. The method is applicable to most geosynthetics. It is also applicable to geogrids, but the specimen dimensions may need to be altered. This test is not applicable to polymeric or bituminous geosynthetic barriers. This method quantifies the tensile strength of a joint or seam between geosynthetics. It can provide data to indicate the joint or seam tensile strength which can be achieved. A joint or seam efficiency can be calculated by comparison of the joint/seam tensile strength with the tensile strength of the unjointed material, as determined by ISO 10319. Procedures for measuring the tensile properties of both conditioned and wet specimens are included. Some modification of techniques may be necessary for particular geosynthetics, e.g. strong geosynthetics, meshes or geosynthetics made from glass fibre, to prevent them from slipping in the jaws or being damaged as a result of being gripped in the jaws. The basic test for joints or seams in all kinds of geosynthetics uses test specimens of 200 mm width, with the provision for the seam or joint to extend for 25 mm on each side, in order to provide joint or seam stability during the test (see Figure 1).
