Geotextiles and geotextile-related products - Characteristics required for use in the construction of tunnels and underground structures

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test methods to determine these characteristics.
The intended use of these geotextiles or geotextile-related products is to protect geosynthetic barriers used in tunnels and underground structures.
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.

EN 13256:2016 (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 13256:2016

EN 13256:2016 (E) 6 1 Scope This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to protect geosynthetic barriers used in tunnels and underground structures. 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. The specification shall define which 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-D 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 13256:2016

EN 13256:2016 (E) 10 4.3 Characteristics relevant to specific conditions of use 4.3.1 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. 4.3.2 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. 4.3.3 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. 4.4 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. 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 SIST EN 13256:2016

EN 13256:2016 (E) 11 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 Protection Elongation at maximum load Protection Static puncture resistance (CBR test) Protection Dynamic perforation resistance (cone drop test) Protection Protection characteristics Protection Durability a Protection a

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 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. SIST EN 13256:2016

EN 13256:2016 (E) 12 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(s) is (are) outside the tolerance value(s), the product is not accepted. 5.6 Initial inspection of factory and of FPC Initial inspection of factory and of FPC shall be carried out when the production process has been finalized and in operation. The factory and FPC documentation shall be assessed to verify that the requirements of 5.4 and Annex A are fulfilled. During the inspection it shall be verified that: a) all resources necessary for the achievement of the product characteristics included in this European Standard are in place and correctly implemented, and b) the FPC-procedures in accordance with the FPC documentation are followed in practice, and c) the product complies with the product type samples, for which compliance of the product performance to the DoP has been verified. All locations where final assembly or at least final testing of the relevant product is performed shall be assessed to verify that the abo

FprEN 13256:2015 (E) 4 European foreword This document (FprEN 13256:2015) has been prepared by Technical Committee CEN/TC 189 “Geosynthetics”, the secretariat of which is held by NBN. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 13256:2014+A1:2015. 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 Regulation No 305/2011. For relationship with Regulation (EU) Nr. 305/2011, see informative Annex ZA, which is an integral part of this document. Annex D provides details of significant technical changes between this European Standard and the previous editions. kSIST FprEN 13256:2016

FprEN 13256:2015 (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. kSIST FprEN 13256:2016

FprEN 13256:2015 (E) 6 1 Scope This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of tunnels and underground structures, and the appropriate test methods to determine these characteristics. The intended use of these geotextiles or geotextile-related products is to protect geosynthetic barriers used in tunnels and underground structures. 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. The specification shall define which 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. kSIST FprEN 13256:2016

Static puncture resistance may not be relevant for some types of products, e.g. GGR, GCO-D 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. kSIST FprEN 13256:2016

FprEN 13256:2015 (E) 10 4.3 Characteristics relevant to specific conditions of use 4.3.1 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. 4.3.2 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. 4.3.3 Resistance to damage during installation EN ISO 10722 may 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. 4.4 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. 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) 1,0 tolerance value(s). kSIST FprEN 13256:2016

FprEN 13256:2015 (E) 11 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 Protection Elongation at maximum load Protection Static puncture resistance (CBR test) Protection Dynamic perforation resistance (cone drop test) Protection Protection characteristics Protection Durability a Protection a

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 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 kSIST FprEN 13256:2016

FprEN 13256:2015 (E) 12 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(s) is (are) outside the tolerance value(s), the product is not accepted. 5.6 Initial inspection of factory and of FPC Initial inspection of factory and of FPC shall be carried out when the production process has been finalized and in operation. The factory and FPC documentation shall be assessed to verify that the requirements of 5.4 and Annex A are fulfilled. During the inspection it shall be verified that: a) all resources necessary for the achievement of the product characteristics included in this European Standard are in place and correctly implemented, and b) the FPC-procedures in accordance with the FPC documentation are followed in practice, and c) the product complies with the product type samples, for which compliance of the product performance to the DoP has been verified. All locations where final assembly or at least final testing of the relevant product is performed shall be assessed to verify that the above conditions a) to c) are in place and implemented. If the FPC system covers more than one product, production line or production process, and it is verified that the general requirements are fulfilled when assessing one product, production line or production process, then the assessment of the general requirements does not need to be repeated when assessing the FPC for another product, production line or production process. All assessments and their results shall be documented in the initial inspection report. The single steps of this inspection are specified in A.2. kSIST FprEN 13256:2016

FprEN 13256:2015 (E) 13 5.7 Continuous surveillance of FPC Surveillance of the FPC shall be undertaken at least once per year. The surveillance of the FPC shall include a review of the FPC test plan(s) and production processes(s) for each product to determine if any changes have been made since the last assessment or surveillance. The significance of any changes shall be assessed. Che
