EN 13492:2004 (E) 5 Introduction This document 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 document can 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 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.

EN 13492:2004 (E) 12 4.3 Characteristics relevant to specific conditions of use. 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 4.3.1 to 4.3.8 4.3.1 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. 4.3.2 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.
4.3.3 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



EN 13492:2004 (E) 13 4.3.7 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. 4.3.8 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
