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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
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/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 221 Geosynthetics.
This fourth edition cancels and replaces the third edition (ISO 10319:2015), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— The term “load” have been changed to “force” for all occurrences;
— Difference between strain and elongation has been clarified in Clause 3, and Fig. 1 has been modified
accordingly;
— Difference between tensile strength at first and second peak has been clarified in Clause 3 and 9.2;
— Illustration of suitable jaws and grips has been introduced in Fig. 3;
— Testing of metallic products has been limited to woven steel wire meshes in Clause 6.3.6;
— Testing products narrower than 200 mm has been introduced in Clause 6.3.7;
— Testing at lower or higher temperatures has been introduced, with the related conditioning in
Clause 7.3 and the related procedure added in Annex A (normative);
— Formulas for strain calculation have been introduced in Clause 9.1;
— Formula for tensile strength of products narrower than 200 mm have been introduced in Clause 9.2;
— Test report requirements have been updated in Clause 10.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Geosynthetics — Wide-width tensile test
1 Scope
This document describes an index test method for the determination of the tensile properties of
geosynthetics (polymeric, glass, and metallic), using a wide-width strip. This document is applicable
to most geosynthetics, including woven geotextiles, nonwoven geotextiles, geocomposites, knitted
geotextiles, geonets, geomats, and metallic products. It is also applicable to geogrids and similar
open-structure geotextiles, but specimen dimensions might need to be altered. It is not applicable to
polymeric or bituminous geosynthetic barriers, while it is applicable to clay geosynthetic barriers.
This document specifies a tensile test method that 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 document.
