Tests for some 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 document is part of a group of standards, addressing the requirements for geosynthetic barriers when used in a specific application.
Particular application cases can 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 document specifies the relevant characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers in the construction of liquid waste disposal sites, transfer stations and secondary containment, and the appropriate test methods to determine these characteristics.
The intended use of these products is to control the leakage of fluids through the construction.
This document is not applicable to geotextiles or geotextile-related products. This document provides for the evaluation of conformity of the product to this document. This document defines requirements to be met by manufacturers and distributors with regard to the presentation of product properties.

This includes the use of a geosynthetic barrier as a basal, side or capping liner. Damage during installation has not been addressed in this document. 4.2 Relevant characteristics The characteristics and the test methods to be used, are given in Table 1. The list of characteristics in Table 1 includes those relevant to all conditions of use and subject to harmonisation (H) (see Annex D), those relevant to all conditions of use and not subject to harmonisation (A), and those relevant to specific conditions of use and not subject to harmonisation (S).
The functions and conditions of use, corresponding with the characteristics, marked with “S” in table 1, are specified in 4.3.
The manufacturer shall provide the data based on the results of tests specified in this document and where relevant, in accordance with 5.1. The manufacturer shall provide information on how functioning joints can be made.

NOTE: 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.
4.3.3 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. 4.3.4 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. 4.3.5 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. 4.3.6
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. SIST EN 13492:2005

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 963. 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 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 document. 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 SIST EN 13492:2005
