Geotextiles and geotextile-related products - Characteristics required for use in solid waste disposals

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in solid waste disposals, and the appropriate test methods to determine these characteristics.
The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation, reinforcement and protection. The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone.
This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318 1.
This European Standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures.
Particular application cases may contain requirements regarding additional properties and – preferably standardized – test methods, if they are technically relevant.
This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in EN 1997 1 (Eurocode 7), e.g. factors of safety. 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.

La présente Norme européenne spécifie les caractéristiques pertinentes des géotextiles et produits apparentés utilisés dans les ouvrages d'enfouissement de déchets solides, ainsi que les méthodes d'essai appropriées pour déterminer ces caractéristiques.
L'utilisation prévue de ces géotextiles ou produits apparentés est de remplir au moins l'une des fonctions suivantes : filtration, séparation, renforcement et protection. La fonction séparation étant toujours utilisée conjointement avec une filtration ou un renforcement, celle-ci n'est pas spécifiée seule.
La présente Norme européenne ne s'applique pas aux géomembranes et géosynthétiques bentonitiques tels que définis dans l'EN ISO 10318 1.
La présente Norme européenne permet d'évaluer et de vérifier la constance des performances du produit à la présente Norme européenne et les procédures de contrôle de la production en usine.
Des cas d'application particuliers peuvent contenir des exigences sur des propriétés supplémentaires et méthodes d'essai – si possible normalisées – si elles sont techniquement pertinentes.
La présente Norme européenne peut être utilisée pour déduire les valeurs de calcul en prenant en compte les facteurs définis dans l'EN 1997 1 (Eurocode 7), par exemple les facteurs de sécurité. Il convient de déterminer la durée de vie prévue du produit, puisque sa fonction peut être provisoire, pour des besoins de construction, ou permanente, pour la durée de vie de la structure.

Geotekstilije in geotekstilijam sorodni izdelki - Značilnosti, ki se zahtevajo pri odstranitvi trdnih odpadkov

Ta evropski standard določa pomembne značilnosti geotekstilij in geotekstilijam sorodnih izdelkov, ki se uporabljajo pri drenažnih sistemih, ter ustrezne preskusne metode za določitev teh značilnosti.
Te geotekstilije in geotekstilijam sorodni izdelki naj bi imeli eno ali več naslednjih funkcij: filtriranje, ločevanje, ojačitev in zaščita. Funkcija ločevanja se bo vedno pojavljala skupaj s filtriranjem ali ojačitvijo, zato ne bo ločeno opredeljena.
Ta evropski standard se ne uporablja za geosintetične zapore, kakor so opredeljene v standardu EN ISO 10318.
Ta evropski standard omogoča ocenjevanje in preverjanje stalnosti funkcionalnosti izdelka v skladu s tem evropskim standardom ter postopke kontrole proizvodnje v obratu.
OPOMBA: Posamezni primeri uporabe lahko vključujejo zahteve glede dodatnih lastnosti in – po možnosti standardiziranih – preskusnih metod, če so tehnično pomembni.
Ta evropski standard se lahko uporablja za izpeljavo projektnih vrednosti ob upoštevanju dejavnikov v okviru definicij iz standarda EN 1997 1 (Evrokod 7), npr. dejavnikov varnosti. Določila naj bi se projektna življenjska doba izdelka, saj je njegova funkcija začasna, kot zagotavljanje primernosti za gradnjo, ali stalna, tj. za življenjsko dobo konstrukcije.

EN 13257:2016 (E) 5 Introduction This European Standard allows manufacturers to describe geotextiles and geotextile-related products 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 the assessment and verification of constancy of performance and factory production control. This European Standard may also be used by designers, end-users and other interested parties to define which functions and conditions of use are relevant. The term “product” used in this European Standard refers to a geotextile or geotextile-related product. This European Standard is part of a series of standards, addressing the requirements for geotextiles and geotextile-related products when used in a specific application. Annex C provides guidance on how to select the appropriate standard. SIST EN 13257:2016

EN 13257:2016 (E) 6 1 Scope This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in solid waste disposals, and the appropriate test methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to fulfil one or more of the following functions: filtration, separation, reinforcement and protection. The separation function will always occur in conjunction with filtration or reinforcement, and hence will not be specified alone. This European Standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318-1. This European Standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures. Particular application cases may contain requirements regarding additional properties and – preferably standardized – test methods, if they are technically relevant. This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in EN 1997-1 (Eurocode 7), e.g. factors of safety. 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

If a drainage or erosion control system is integrated in the construction, the requirements of the appropriate standards shall also be fulfilled. As the separation function is always used in conjunction with another function, the separation function shall never be specified alone. SIST EN 13257:2016

EN 13257:2016 (E) 9 The specification shall define which functions and conditions of use are relevant (see Table 1). The producer shall provide the necessary data based on the requirements and test methods specified in this European Standard, as described in 5.1. The characteristics, their relevance to the conditions of use, and the test methods to be used, are specified in Table 1. The list of characteristics in Table 1 includes those relevant to all conditions of use (A), and those relevant to specific conditions of use (S). The indication “–” means that the characteristic is not relevant for that function. Where, for the same property, data for more than one function shall be provided, the following ranking order shall be observed: A overrules S, and S overrules “–”. The functions and conditions of use, corresponding with the S-coded characteristics in Table 1, are specified in 4.3. Durability shall be assessed in accordance with the requirements of Annex B. 4.2 Selection of the appropriate standard in a specific application Guidelines for the selection of the appropriate standard in a specific application are given in Annex C.

Static puncture resistance may not be relevant for some types of products, e.g. GGR, GCO-R or GST. b

If the mechanical properties (tensile strength and static puncture) are coded “A” in this Table, the use of only one, either tensile strength or static puncture, is usually sufficient in a project specification. c

The strength of internal structural junctions of geocells shall be tested in accordance with EN ISO 13426-1. d

The strength of internal structural junctions of geocomposites shall be tested in accordance with EN ISO 13426-2. SIST EN 13257:2016

EN 13257:2016 (E) 12 4.3 Characteristics relevant to specific conditions of use 4.3.1 Stiffness at 2 %, 5 % and 10 % Data on stiffness are necessary for the reinforcement function if the deformation of the structure needs to be evaluated. 4.3.2 Tensile strength of seams and joints Data on tensile strength of seams and joints are necessary for all functions if the product is to be mechanically jointed and if load is transferred across the seams and joints. 4.3.3 Static puncture Data on static puncture or - as an alternative - on tensile strength, are necessary for the filtration function if required by the specification, i.e. when the site loading conditions are such that there is a potential risk of static puncture of the filter layer. 4.3.4 Friction characteristics Data on friction characteristics are necessary for the functions separation and filtration when the product is used in a situation where a differential movement can take place between the product and adjacent material that may endanger the stability of the works. The friction characteristics can be measured, using site specific materials, by a direct shear test according to EN ISO 12957-1 or, in the case of loads up to 5 kPa, by an inclined plane test according to EN ISO 12957-2. Friction behaviour with the adjacent construction materials, e.g. the soil or the geosynthetic barrier, should also be considered. 4.3.5 Tensile creep Data on tensile creep can be used to give an indication of the resistance to sustained loading, when the product fulfils a reinforcement function. 4.3.6 Resistance to damage during installation EN ISO 10722 can be used as an index test giving the relative performance of the product. Testing with site specific soil and conditions may give more relevant results for specific design. 4.3.7 Protection efficiency (EN 14574) Data on protection efficiency in accordance with EN 14574 are necessary when there is a risk that the barrier material be punctured by sharp objects or materials. 4.3.8 Water permeability normal to the plane Data on water permeability are necessary when the reinforced structure is subject to water flow. 4.4 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 European Standard are placed on those markets. In the absence of European harmonized 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 http://ec.europa.eu/growth/tools-databases/cp-ds/index_en.htm. SIST EN 13257:2016

EN 13257:2016 (E) 13 5 Assessment and verification of constancy of performance (AVCP) 5.1 General The compliance of geotextiles and geotextile-related products with the requirements of this European Standard and with the declared values shall be demonstrated by: — Product type determination (PTD); — Factory production control (FPC) by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the product. 5.2 Presentation of characteristics The characteristics specified in Table 2, except for durability, shall be expressed as mean values and tolerance value(s) corresponding to the 95 % confidence level. The values expressed may be verified using the procedure referred to in 5.5. NOTE The 95 % confidence level corresponds to the mean value minus (and/or plus) a tolerance value (see Annex ZA, table ZA1.X column Notes). Both the mean value and the tolerance value are defined by the manufacturer to be representative of the performance of the product for the corresponding characteristic (these two values are not necessarily based on a statistical calculation). Information on durability shall be expressed in accordance with Annex B. 5.3 Product type determination (PTD) PTD 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. PTD 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 PTD tests are those for the properties which are affected or shall be confirmed 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 from the characteristics specified in Table 2, consistent with the product’s intended use: Table 2 — Characteristics required for PTD and AVCP Characteristic Functions Tensile strength Filtration, separation, reinforcement, protection Elongation at maximum load Filtration, separation, reinforcement, protection Static puncture resistance (CBR test) Separation, reinforcement, protection Dynamic perforation resistance (cone drop test) Separation, filtration, reinforcement, protection Protection characteristics Protection Characteristic opening size Filtration, separation Water permeability normal to the plane Filtration, separation SIST EN 13257:2016

For the durability aspects, see Table 1 and Annex B. The results of PTD tests shall be recorded and be available for inspection. The sample for the PTD tests shall be drawn according to EN ISO 9862 from a normal production run using the same materials and forming processes as 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 PTD tests. 5.4 Factory production control (FPC) A FPC scheme shall
