Introduction
This European Standard allows manufacturers to describe geosynthetic barriers on the basis of declared values for
characteristics relevant to the intended use and if tested to the specified method. It also includes procedures for
evaluation of conformity and factory production control.
This European Standard may also be used by designers, end-users and other interested parties as a tool to define
relevant and appropriate characteristics for specifications and on-site quality control. It should be emphasised
however that not all characteristics and test methods quoted in this document are suitable for the purpose of on-site
quality control.
Tests for several non-mandated characteristics are still under study and will be included when the standard is
revised.
The term “product” used in this document refers to a geosynthetic barrier, including polymeric geosynthetic barriers,
clay geosynthetic barriers and bituminous geosynthetic barriers.
This European Standard is part of a group of standards, addressing the requirements for geosynthetic barriers
when used in a specific application.
Particular application cases may contain requirements about additional properties and - preferably standardised -
test methods, if they are technically relevant and not conflicting with European Standards.
The design life of the product should be determined, since its function may be temporary, as a construction
expediency, or permanent, for the lifetime of the structure.

4.1 General
The main function of geosynthetic barriers when used in the construction of canals is to prevent or reduce the flow
of fluid through the structure. Damage during installation has not been addressed in this document.
4.2 Types of Application
NOTE It is not normally advisable to install a geosynthetic barrier on the outside face of a canal embankment. Special
consideration should be given to any geosynthetic barrier installed on the downstream face of a canal. The applications
described in this document do not include such situations.

4.4 Characteristics relevant to specific conditions of use
4.4.1 General
The specification shall define which functions and conditions of use are relevant (see Table 1). The producer
of the product shall provide the necessary data based on the requirements and test methods described in this
document.
The list of characteristics in Table 1 includes those required for harmonisation (H), those relevant to all
conditions of use (A), and those relevant to specific conditions of use (S). These specific conditions of use are
listed from 4.4.2 to 4.4.9
4.4.2 Tear strength
Data on the tear strength of polymeric and bituminous barriers are required when they are laid on slopes or
inclined surfaces or otherwise exposed to mechanical stress.
4.4.3 Bursting strength
Data on the bursting strength are required in all applications where multi-axial deformation of geosynthetic
barriers can occur as a result of settlement, deformation in designed or accidental situations.
4.4.4 Friction characteristics (direct shear and inclined plane tests)
Data on friction characteristics are required in all applications where differential movement may take place
between the product and adjacent materials including, but not by way of limitation, geosynthetic barriers
applied to slopes and certain types of anchoring arrangements.
NOTE 1 In addition to the friction characteristics information on the internal bonding strength of GBR-C in the direction
of the actual stress may be relevant. A shear or peel test may be appropriate, particularly on slopes or in applications
where shear stress may occur (i.e. during installation).
NOTE 2 Site specific testing should be carried out to establish the friction characteristics between all the materials
used.
4.4.5 Low temperature behaviour
Data on low temperature behaviour are required for applications where polymer and bituminous products may
be exposed to low temperatures in storage, construction, and use
NOTE Tests which set simple pass/fail criteria at a single temperature condition may not be appropriate for this
purpose.
Prehydrated GBR-C should not be stored or installed when the ambient temperature is below 0° C.
4.4.6 Weathering
Data on weathering (combined effects of cycles of wetting, temperature change, and exposure to UV light) are
required for applications where the GBR-C barrier will be exposed to weathering without adequate protective
cover. It should be noted that in all normal situations GBR-C barriers should be covered with soil or other
revetment on the same working day or prior to any circumstances which could cause a hydration of the clay
component.
4.4.7 Resistance to wetting and drying
Data on the resistance of GBR-C to repeated wetting and drying is required when the conditions of use will
subject the product to this sequence of actions.

---------------------- Page: 16 ----------------------
SIST EN 13362:2005
EN 13362:2005 (E)
4.4.8 Freeze-thaw cycle resistance
Data on the resistance of GBR-C to freeze/thaw is required when the conditions of use will subject the product
to this sequence of actions.
4.4.9 Resistance to root penetration
Data on root penetration is required in all applications where the geosynthetic barrier is exposed to soils
containing restorative vegetation.
5 Evaluation of conformity
5.1 Presentation of characteristics
The characteristics specified in Table 2, except for durability, expressed as mean values and tolerance limit(s)
corresponding to the 95% confidence level, shall be given by the manufacturer, based on the statistical
interpretation of his internal quality control measurements.
Physical examination or preliminary testing, according to one of the test methods referenced in Table 1, may
indicate that values obtained for a product lie below (or above) the sensitivity threshold established for that
test method. In these particular circumstances the manufacturer may declare a value as being less (or
greater) than this sensitivity threshold value.
Information about durability shall be expressed in accordance with the guidelines of Annex B.
5.2 Verification of values
The marking and labelling of the rolls and of the products shall be checked. The marking of the products shall
be according to EN ISO 10320.
NOTE The method described in this clause is not compulsory for an on-site control procedure.
The compliance of characteristics with the values defined in 5.1 shall be based on measurements made on
two representative samples (A and B), taken from two different rolls. Sampling shall be made in accordance
with EN ISO 9862.
The characteristics given in Table 2 shall be measured in accordance with the corresponding European
standards on specimens prepared from sample A.
If the test result(s) for a particular characteristic is (are) within the tolerance limit(s) given by the manufacturer,
the product is accepted as complying with respect to this characteristic.
If the test result(s) for a particular characteristic is (are) outside the tolerance limit(s), specimens prepared
