4 Foreword This document (EN 15382:2013) has been prepared by Technical Committee CEN/TC 189 “Geosynthetics”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2014, and conflicting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 15382:2008. Annex C provides details of significant technical changes between this European Standard and the previous edition. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive. For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
5 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 European Standard 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 standard 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.
1 Scope This European Standard specifies the relevant characteristics of geosynthetic barriers (polymeric, clay and bituminous geosynthetic barriers), used as fluid barriers in infrastructure works, e.g. roads, railroads, runways of airports, and the appropriate test methods to determine these characteristics. Tunnels and underground structures are addressed in EN 13491. The intended use of these products is to control the pathway of liquids through the construction and to limit any contamination, e.g. by de-icing products, of groundwater or water sources. This European Standard is applicable to geosynthetic barriers, but not to geotextiles or geotextile-related products, as defined in EN ISO 10318. This European Standard provides for the evaluation of conformity of the product to this European Standard. This European Standard defines requirements to be met by manufacturers and their authorised representatives with regard to the presentation of product properties.
This European Standard does not cover applications where the geosynthetic barrier will be in contact with water that has been treated for human consumption. In these cases other relevant standards, requirements and/or regulations should be observed. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Particular application cases may call for additional requirements, e.g. due to specific design features or conditions of use. These additional requirements should be technically relevant and preferably be measured by standardised test methods, described in European or International 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.
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 (EN ISO 12957 and ASTM D 6243) or peel (EN ISO 13426-1 and EN ISO 13426-2 and/or ASTM D 6496 (for needle punched GBR-C)) test may be appropriate, particularly on slopes or in applications where shear stress may occur (i.e. during installation).
Site specific testing should be carried out to establish the friction characteristics between all the materials used.
4.4.4 Chemical resistance Depending on the application and the liquids involved, chemical testing according to EN 14414 may be applicable. 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. 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 a GBR-C 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 on the same working day or prior to any circumstances which could cause a hydration of the clay component. SIST EN 15382:2013

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. NOTE Installations close to the surface will always be subjected to drying periods. 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 are required in all applications where the geosynthetic barrier is exposed to soils containing restorative vegetation.
NOTE 1 Slopes in infrastructure will usually be vegetated. Therefore an "A", as defined in 4.2, is recommended.
NOTE 2 Only applications underneath embankments of infrastructure or in the central area of multilane highways form an exception: no frost, no roots, no drying effects, no traffic loads after installation.
4.5 Release of dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonised test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/ 5 Evaluation of conformity 5.1 General The compliance of the geosynthetic barriers with the requirements of this European Standard and with the stated values shall be demonstrated by:  Initial type testing (5.3);  Factory production control (5.4) by the manufacturer, including product assessment. 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 provided 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 Annex B. SIST EN 15382:2013

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 from sample B shall be tested. If the test result(s) of the sample B specimens for the same characteristic are within the given tolerance limit(s), the product is accepted as complying with respect to that characteristic. If the test result(s) is (are) outside the tolerance limit(s), the product is not accepted. 5.3 Initial type tests Initial type tests shall be carried out by the manufacturer to define the values of the properties to be declared for the product to satisfy the requirements of this European Standard. Initial type tests shall also be carried out on existing products when a change in the basic materials or manufacturing procedures affects the declared properties or the use of a product. In these cases the appropriate initial type tests are those for the properties which are affected or need confirming and new properties introduced by a change of use. The tests to be conducted shall be reference tests as specified in this European Standard and shall be selected for the characteristics specified in Table 2, consistent with the product’s intended use: Table 2 — Characteristics required for initial type testing and evaluation of conformity Characteristica
Functions tensile strength fluid barrier static puncture (CBR test) fluid barrier liquid tightness fluid barrier durability fluid barrier a For the durability aspects of these characteristics, see Table 1, 4.4 and Annex B.
The results of initial type tests shall be recorded and be available for inspection. The sample for the type tests shall be drawn according to EN ISO 9862 from a normal production run using the materials and forming processes to be used for the full production process. The size of the sample shall be big enough to allow the determination of the characteristics specified in Table 2. Handmade samples, short trial batches and other development prototypes may be tested by the same methods, but shall not be used for establishing characteristic values in type tests.
The factory production control procedures shall consist of a system for the permanent internal control of the production of the products to ensure that such products comply with this standard and that the measured values conform with the declared values.
Annex A (normative) lists all the items that shall be considered to determine which is appropriate for the control exercised for a product. The manufacturer shall establish the applicable items and record them in his factory production control manual.
When relevant the procedure given in 5.2 shall be used to check the conformity of the product, for one or more of the characteristics. 5.5 Inspection
When required, inspection of the factory and of the factory production control shall be made on the provisions contained in 5.4 and Annex A. 6
Marking
The manufacturer shall clearly and indelibly mark the geosynthetic barrier with the information specified in EN ISO 10320. NOTE For CE Marking, see ZA.3. SIST EN 15382:2013

Factory production control – Factory production control scheme A.1 General The items to be addressed in the factory production control manual relating to the system of control determined from 5.4 are given in Annex A.
