EN 13249:2000 Foreword This European Standard has been prepared by Technical Committee CEN/TC 189 "Geosynthetics", the secretariat of which is held by IBN. 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of an identical text or by endorsement, at the latest by June 2001, and conflicting national standards shall be withdrawn at the latest by September 2002. This European Standard 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 standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This 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 evaluation of conformity and factory production control. This standard may also be used by designers, end-users and other interested parties to define which functions and conditions of use are relevant. Performance tests for several characteristics are still under study and will be included when the standard is revised. The term "product" used in this 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. In annex C guidance is given on how to select the appropriate standard. 1 Scope This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of roads and other trafficked areas (excluding railways and asphaltic inclusion), 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 and reinforcement. The separation function is always used in conjunction with filtration or reinforcement, accordingly separation will never be specified alone. This standard is not applicable to geomembranes. This standard provides for the evaluation of conformity of the product to this European Standard and for factory production control procedures. This standard defines requirements to be met by manufacturers and distributors with regard to the presentation of product properties.

EN 13249:2000

NOTE 1 Particular application cases or national specifications may contain requirements regarding additional properties and preferably standardised test methods, if they are technically relevant and not conflicting with European Standards.

NOTE 2 This European Standard may be used to derive design values by taking into account factors within the context of the definitions given in Eurocode 7 (ENV 1997-1), 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 This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are quoted at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

The term "product" used in this standard refers to a geotextile or geotextile-related product. Furthermore the following term and definition apply: 3.1.1 specification any document in which the work, functions and specific conditions of use of the product are described 3.2 Abbreviations For the purposes of this European Standard the following abbreviations from EN ISO 1043-1 apply: PA: polyamide PE: polyethylene PET: polyethylene terephthalate (polyester) PP: polypropylene Furthermore the following abbreviations apply: MD: machine direction CMD: cross machine direction 4 Required characteristics and corresponding methods of test 4.1 General The main functions of geotextiles and geotextile-related products used in the construction of roads and other trafficked areas are filtration, separation and reinforcement. If a drainage or erosion control system is integrated in the construction, the requirements of the appropriate standards shall also be fulfilled (see annex C). The characteristics, their relevancy to the conditions of use, and the test methods to be used, are given in Table 1. The list of characteristics in Table 1 includes those essential to harmonisation (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 characteristics, marked with "S" in Table 1, are specified in 4.2. As the separation function is always used in conjunction with another function, the separation function shall never be specified alone. The producer of the geotextile or geotextile-related product shall provide the data based on the results of tests specified in this standard, as described in 5.1. For the assessment of durability aspects the rules described in annex B shall be observed.

a It should be considered that this test may not be applicable for some types of products, e. g. geogrids. b If the mechanical properties (tensile strength and static puncture) are coded "H" in this table, the producer shall provide data for both. The use of only one, either tensile strength or static puncture, is sufficient in the specification.

EN 13249:2000 4.2 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 standard. The list of characteristics in Table 1 includes those required for harmonization (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 4.2.1 to 4.2.4. 4.2.1 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. 4.2.2 Static puncture Data on static puncture are necessary for the function filtration if required by the specification. When the site loading conditions are such that there is a potential risk of static puncture of the filter, data on static puncture or, as an alternative, on tensile strength, shall be supplied. 4.2.3 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 prEN ISO 12957-1:1997 or, in the case of loads up to 50 kPa, by an inclined plane test according to prEN ISO 12957-2:1997.

NOTE Friction behaviour with the adjacent construction materials, e. g. the soil or the geomembrane, should also be considered.

4.2.4 Tensile creep (reinforcement) Data on tensile creep may be used to give an indication of the resistance to sustained loading, when the product fulfils a reinforcement function. 5 Evaluation of conformity 5.1 Presentation of characteristics The characteristics specified in Table 2, except for durability, expressed as mean values and tolerance value(s) corresponding to the 95% confidence level, shall be given by the manufacturer, based on the statistical interpretation of his internal quality control measurements. Information on 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 963.

EN 13249:2000

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.

NOTE The 95% confidence level corresponds to the mean value minus (and/or plus) 1,0 tolerance value(s).

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. 5.3 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 standard. 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 initial type 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 standard and shall be selected from the characteristics specified in Table 2, consistent with the products intended use:

Table 2 Characteristics required for initial type testing and evaluation of conformity

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 963 from a normal production run using the same materials and forming processes as 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.

EN 13249:2000 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 affect 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 permanent internal production control system to ensure that such products comply with this standard and that the measured values conform with the declared values. 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 characteristics. 5.5 Inspection When required, inspection of the factory and of the factory production control shall be made on the provisions contained in 5.4 and annex A. 6 Marking The manufacturer shall clearly and indelibly mark the geotextile or geotextile-related product with the information specified in EN ISO 10320.

NOTE For CE marking see ZA.3.

Annex B

(normative)

Durability aspects B.1 Weathering All geotextiles and geotextile-related products shall pass the accelerated weathering test according to EN 12224, unless they are to be covered on the day of installation. The strength retained by the product at the end of this test, together with the specific application of product, will determine the length of the time that the material may be exposed on site. The maximum exposure times are given in Table B.1. Extended testing is necessary for materials, which shall be exposed for longer duration.

Table B.1 Maximum exposure times

Application Retained strength Maximum time of exposure after installation

Reinforcement or other applications where long-term strength is a significant parameter

> 80 % 1 montha

60 % to 80 % 2 weeks

< 60 % 1 day

Other applications > 60 % 1 montha

20 % to 60% 2 weeks

< 20 % 1 day a Exposure of up to 4 months may be acceptable depending on the season and on the location in Europe.

A geotextile or geotextile-related product, which has not been tested for resistance to weathering shall be covered within 1 day.

For a range of products identical except for mass per unit area, initially only the product with the lowest mass per unit area should be subjected to the tests. The results of the test may be applied for the other products in the range, unless they have been tested separately.

The product information shall state: "To be covered within (duration) after installation". B.2 Required service lives up to five years A geotextile or geotextile-related product which:

consists of polyester (polyethylene terephthalate), polyethylene, polypropylene, polyamide 6 or polyamide 6.6, or a combination of these, and

contains no post-consumer recycled material

may be considered as having sufficient durability for a minimum service life of five years provided that it is used:

in an application which is non-reinforcing and where long-term strength is not a significant parameter, and

in natural soils with a pH of between 4 and 9, and

at a soil temperature < 25 C.

EN 13249:2000 The product information shall state : "Predicted to be durable a minimum of five years for non-reinforcing applications in natural soils with 4 < pH < 9 and soil temperatures < 25 C". B.3 Required service lives up to 25 years B.3.1 General A geotextile or geotextile-related product which:

consists of polyester (polyethylene terephthalate), polyethylene, polypropylene, polyamide 6 or 6.6, or a combination of these, and

contains no post-consumer recycled material

may be considered as having sufficient durability for a minimum service life of 25 years provided that it is used:

in natural soils with a pH of between 4 and 9, and

at a soil temperature < 25 C, and

provided that it passes the appropriate tests in B.3.2. A geotextile or geotextile-related product consisting of more than one polymer shall be separated into its constituent parts which shall pass the appropriate tests in B.3.2. If this is not possible, the geotextile or geotextile-related product shall pass all the appropriate tests in B.3.2 or be assessed separately as described in B.4. The product information shall contain the following:

"Predicted to be durable for a minimum of 25 years in natural soils with 4 < pH < 9 and soil temperatures < 25 C"

plus one of the following statements:

"product (state product as described in B.3.2) having passed the following tests (state tests and results)", or

"On the basis of service experience as reported in (state relevant document according to B.3.3)".

NOTE This annex doesnt refer to change of mechanical properties due to low soil temperatures (below 0 C), nor to effect of frozen soil.

For a range of products identical except for mass per unit area then initially only the product with the lowest mass per unit area should be subjected to the tests in B.3.2.1 to B.3.2.4. If this product passes the test, the other products in the range may also be deemed to do so. B.3.2 Tests for specific materials B.3.2.1 Test for polyester A geotextile or geotextile-related product consisting solely of polyester (polyethylene terephthalate) and containing no post-consumer recycled material shall be tested for resistance to internal hydrolysis in accordance with ENV 12447. The minimum percentage retained strength shall be 50%.

EN 13249:2000

NOTE A geotextile or geotextile-related product that fulfils this requirement is estimated to have the following minimum retained strengths in saturated soil after 25 years:

at 25 C: 95 % at 30 C: 90 % at 35 C: 80 %

B.3.2.2 Test for polypropylene A geotextile or geotextile-related product consisting solely of polypropylene and containing no post-consumer recycled material shall be tested for resistance to oxidation to ENV ISO 13438. The minimum percentage retained strength shall be 50%. B.3.2.3 Test for polyethylene A geotextile or geotextile-related product consisting solely of polyethylene and containing no post-consumer recycled material shall be tested for resistance to oxidation to ENV ISO 13438. The minimum percentage retained strength shall be 50%. B.3.2.4 Tests for polyamide A geotextile or geotextile-related product consisting solely of polyamide 6 or polyamide 6.6 and containing no post-consumer recycled material shall be tested for resistance to oxidation to ENV ISO 13438 and for resistance to hydrolysis to ENV 12447. The minimum percentage retained strength shall be 50% for each test. B.3.3 Alternative procedure based on service experience Testing may be omitted and the evidence of satisfactory experience reported in its place, if, for any of the geotextile or geotextile-related products and conditions of use specified in B.3.2, 25 years of service life can be demonstrated:

under similar site conditions (within the values specified in B.3.1)

for a geotextile or geotextile-related product where the raw materials and production technology have remained the same, or

for a product using the same yarns and polymers and comparable production technology.

B.4 Other geotextiles or geotextile-related products or conditions of use For materials and conditions of use other than those specified in B.2 and B.3 the geotextile or geotextile-related product shall be assessed for durability with regard to the proposed conditions of use. This includes testing for microbiological resistance according to EN 12225 and applies in particular to any of the following:

service lives longer than 25 years;

soil temperatures > 25 C;

use in contaminated soils, particularly in the presence of ammonium salts;

combinations of different polymers and composite structures which cannot be tested as described in B.3.2;

post-consumer recycled or regenerated materials;

geotextiles or geotextile-related products exposed to highly acid or alkaline environments.

EN 13249:2000 For severe environments or for service lives longer than five years it is advisable not to use post-consumer recycled polymer without specific proof of its long-term durability. The composition and origin of the polymer should be assured. Assessment of a geotextile or geotextile-related product due to be exposed to a soil with pH < 4 or pH > 9 shall include testing according to ENV ISO 12960. Method A shall be used if the pH is < 4 and method B shall be used if the pH is > 9. In both cases the percentage retained strength shall be greater than 50%. The results should be interpreted in the context of the local site conditions.

NOTE For reinforcement applications a further assessment may be required to predict the loss of strength of the product during its service life, and to derive reduction of partial safety factors for reinforced soil design. In cases where the products are (or may be) in direct contact with solid or liquid waste, its leachates or gases, the durability should be assessed with regard to the expected chemical and thermal environment.

For further information check in accordance with CR ISO 13434. Geotextile and geotextile-related products assessed according to this clause shall be stated as "Predicted to be durable for more than (duration) years in (conditions) on the basis of a durability assessment (reference to document)".

NOTE Annex D presents a flow chart of the process of evaluation of durability

Annex C

(informative)

Guidelines for the selection of the appropriate standard in a specific application This group of European standards was developed to specify the characteristics relevant to the use of geotextiles and geotextile-related products in particular applications or works. Sometimes, however, an application can be considered as a part of an other application. In such cases it is not clear which standard to use. Table C.1 shows how to select the appropriate standard depending on the application. The following steps should be used in this selection process. 1. Select the application from column 1 (vertical) of the table; 2. Check if the relevant application is mentioned in row 1 (horizontal) in columns 3 to 6

if not, use the standard quoted in column 2;

if yes, use the standard quoted at the intersection of the first applicable row and first applicable column

EXAMPLES:

a drainage trench in a road: row 2 and column 3 apply and EN 13252 should be used;

a retaining structure in a railway: row 3 and column 6 apply and EN 13251 should be used, since in this case H > Hc;

an external erosion control system in a canal: row 5 and column 4 apply and EN 13253 should be used;

a drainage for a road in a tunnel: row 2 and column 3 apply and EN 13252 should be used, not EN 13256 (at the intersection of row 2 and column 5);

a protection layer for a road tunnel: row 2 and column 5 apply and EN 13256 should be used;

a drainage system in a retaining wall: row 9 and column 3 apply and EN 13252 should be used.

Annex A

The system allows for non-determination of a certain characteristic where at least one Member State has no legal requirement at all for such characteristic. In this case the verification of such a characteristic is not imposed on the manufacturer if he does not wish to declare the performance of the product in that respect in this Member State. In this case, the manufacturer willing to place his products in the market of this Member State is not obliged to determine nor to declare the performance of his products with regard to this characteristic. The option "no performance determined" in the information accompanying the CE marking may be then used. The no performance determined option may not be used when the characteristic is subject to a threshold level.

EN 13249:2000

When compliance with the system of attestation of conformity is achieved, the notified body shall draw up a certificate of the factory production control including the following information:

name, address and identification number of the notified body; name and address of the manufacturer, or his authorised representative established in the EEA and place of production; description of the product (type, identification, use,...); provisions to which the product conforms (this European Standard); particular conditions applicable to the use of the product; the certificates number; conditions and period of validity of the certificate; name of, and position held by, the person empowered to sign the certificate.

In addition, for each product, the manufacturer shall draw up a declaration of conformity (EC declaration of conformity) including the following information:

name and address of the manufacturer, or his authorised representative established in the EEA; number of the attached certificate of factory production control; name of, and position held by, the person empowered to sign the declaration on behalf of the manufacturer or of his authorised representative.

This declaration of conformity entitles the manufacturer to affix the CE marking, as described in ZA.3. The above mentioned certificate and declaration shall be available in the official language(s) of the Member State in which the product is to be used.

EN 13249:2000 ZA.3 CE marking and labelling The manufacturer or his authorised representative established within the EEA is responsible for the affixing of the CE marking. The CE conformity symbol to affix shall be in accordance with Directive 93/68/EC and shall be accompanied by the following information:
