Geotextiles and geotextile-related products - Characteristics required for use in the construction of canals
This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of canals, 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.
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.
NOTE Particular application cases may contain requirements regarding additional properties and – preferably standardised – 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.

Geotekstilije in geotekstilijam sorodni izdelki - Značilnosti, ki se zahtevajo pri gradnji kanalov
Ta evropski standard določa pomembne značilnosti geotekstilij in geotekstilijam sorodnih izdelkov, ki se uporabljajo pri gradnji kanalov, ter ustrezne preskusne metode za določitev teh značilnosti.
Te geotekstilije in geotekstilijam sorodni izdelki naj bi imeli eno ali več naslednjih funkcij: filtriranje, ločevanje, armiranje in zaščita. Funkcija ločevanja se bo vedno pojavljala skupaj s filtriranjem ali armiranjem, zato ne bo ločeno opredeljena.
Ta evropski standard ne velja za geosintetične zapore, kakor so opredeljene v standardu EN ISO 10318.
Ta evropski standard omogoča ocenjevanje in preverjanje stalnosti delovanja 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 možnost 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.

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. 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 needed for regulatory purposes (H), 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: H overrules A, 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.

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 may be used to give an indication of the resistance to sustained loading, when the product fulfils a reinforcement function. 4.3.6 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 the Construction website on EUROPA accessed through: httptiiec.europa.euienterpriseiconstructionicpd-dsi.

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) 1,0 tolerance value(s). 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) Filtration, reinforcement, protection Protection characteristics Protection Characteristic opening size Filtration, separation Water permeability normal to the plane Filtration, separation Durability a Filtration, separation, reinforcement, protection a For the durability aspects, see Table 1 and Annex B. SIST EN 13255:2014+A1:2015
EN 13255:2014+A1:2015 (E) 13 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 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 affect the properties or use of a product shall be recorded in the manual. The manual shall include the FPC procedures relevant to the declared properties, as confirmed by the product type determination. The FPC procedures shall consist of a permanent internal production control system to ensure that such products comply with this European Standard and that the measured values conform to the declared values. Annex A (normative) lists all the items that shall be considered to determine the appropriate control measures for a product. The manufacturer shall establish control measures for the relevant items and record them in his FPC manual. These measures shall be described in detail, including the type of tests to be performed and the frequency of these tests (see also A.2). When relevant, the procedure given in A.2.3 shall be used to check the conformity of the product for one or more characteristics. 5.5 Verification of values If verification of values is required, the compliance of characteristics with the values defined in 5.2 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. For on-site quality control purposes CEN/TR 15019 may also be considered. 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 value(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 1,5 times the tolerance value(s), the product does not comply with respect to that characteristic. If the test result(s) for a particular characteristic is (are) within 1 and 1,5 times the tolerance value(s), specimens prepared from sample B shall be tested. If the test result(s) of the sample B specimens for the same characteristic is (are) within the given tolerance value(s), the product is accepted as complying with respect to that characteristic. If the test result(
