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of an identical text or by endorsement, at the latest by November 2005, and conflicting national standards shall be withdrawn at the latest by February 2007. 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(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 13493:2005 (E) 4 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 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 standard 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 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 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. SIST EN 13493:2005

EN 13493:2005 (E) 12 4.3 Characteristics relevant to specific conditions of use 4.3.1 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 4.3.2 to 4.3.10. 4.3.2 Gas permeability Whenever a GBR-C is used as the sole gas barrier it shall be ensured that the GBR-C remains hydrated in use to act as a gas barrier. NOTE At present there is no standardised test method for the determination of gas permeability of GBR-Cs. The test procedure described in Annex C is currently experimental and can be used for information. 4.3.3 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. 4.3.4 Burst strength Data on the burst 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. 4.3.5 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. 4.3.6 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. SIST EN 13493:2005
EN 13493:2005 (E) 13 4.3.7 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 weather 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. 4.3.8
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. 4.3.9 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. 4.3.10 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. SIST EN 13493:2005
EN 13493:2005 (E) 14 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 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 document 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 Characteristic a Functions tensile strength fluid and gas barrier static puncture (CBR test) fluid and gas barrier liquid tightness fluid and gas barrier gas tightness gas barrier durability fluid and gas barrier a For the durability aspects of these characteristics, see Table 1, 4.3 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. 5.4 Factory production control A factory production control scheme shall be established and documented in a manual prior to a product type being placed on the market. Subsequently, any fundamental changes in raw materials and additives, manufacturing procedures or the control scheme that affects the properties or use of a product shall be recorded in the manual. The manual shall include the factory production control procedures relevant to the declared properties, as confirmed by the initial 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 European Standard and that the measured values conform with the declared values. SIST EN 13493:2005
EN 13493:2005 (E) 15 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 Inspec
