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 second edition cancels and replaces the first edition (ISO 13426-2:2005) which has been technically
revised.
The main changes are as follows:
— In clause 9 modification of the calculation of the junction strength for tests with multiple peaks
A list of all parts in the ISO 13426 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Part 2:
Geocomposites
1 Scope
This document describes index tests for determining the strength of the internal structural junctions
under different loading conditions of all geocomposites and of clay geosynthetic barriers .
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 10318-1, Geosynthetics — Part 1: Terms and definitions
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 10318-1 and the following
apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:

3.1
failure
point at which a geosynthetic ceases to be functionally capable of its intended use
Note 1 to entry: A material may be considered to have failed without rupture.
3.2
geocomposite
manufactured, assembled material using at least one geosynthetic product among the components,
used in contact with soil and/or other materials in geotechnical and civil engineering applications
3.3
junction
point or line where two of the geosynthetics components are connected
3.4
junction strength
peak load attained during the test, reported to the unit width of the product
Note 1 to entry: The junction strength is expressed in kilonewtons per metre (kN/m).
