Geotextiles and geotextile-related products - Characteristics required for use in drainage systems

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in drainage systems 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 drainage. The separation function is always used in conjunction with filtration or drainage. Accordingly separation will never be specified alone.
This standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318..
This standard provides for the assessment and verification of constancy of performance 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.

This draft amendment is submitted to CEN members for unique acceptance procedure. It has been drawn up by the Technical Committee

CEN/TC 189.

This draft amendment A1, if approved, will modify the European Standard EN 13252:2014. If this draft becomes an amendment, CEN

members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment

into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made

by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has

the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,

Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United

Kingdom.

Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are aware and to

provide supporting documentation.

Warning : This document is not a European Standard. It is distributed for review and comments. It is subject to change without notice and

shall not be referred to as a European Standard.

Foreword

This document (EN 13252:2014/FprA1:2014) 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 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.

NOTE Due to fact that the Framework Partnership Agreement between the Commission and CEN & CENELEC is not

signed yet, there are currently no New Approach Consultants in place for 2014. Therefore the provisions of CEN-

CENELEC Guide 15 cannot be met.

This shall not prevent the processing of draft standards nor the offering of harmonized standards to the Commission. In

particular, draft standards can be sent to vote without Consultant assessment.
This note will be removed from the Foreword of the finalized publication.

Annex B
(normative)
Durability aspects
B.1 General
B.1.1 Service life

The provisions and assessment methods of this annex are based upon the intended use of geosynthetics, as

specified in the scope of this European Standard, and their foreseen service life in years. They are based

upon the current state of the art, knowledge and experience. The service life refers to the period during which

the geosynthetic retains the required properties of this annex, assuming it was properly installed, used and

maintained.

For a geosynthetic which satisfies the requirements of this annex the service life represents a minimum

indication. The real service life, for normal conditions of use, may turn out to be considerably longer without

major degradation affecting the essential requirements of the works defined in the CPR.

The indicated service life of the geosynthetic cannot be interpreted as a guarantee given by the manufacturer

but should be regarded only as a tool for selecting a product suitable for the anticipated working life.

The tests described in this annex do not allow the determination of reduction factors. The tests described in

this annex are screening tests to show the ability of a product to serve for a certain time. The reference

strength and retained strength of products investigated in this Annex B shall be determined in the same way in

accordance with EN 12226.
B.1.2 Initial and repeat testing of durability

A product shall be submitted to an initial testing of its durability in accordance with this annex.

A product that is unchanged shall be tested again after 5 years. A product is considered unchanged if the raw

material supply, the production technology and the process and stabilization of the product have not been

subject to a significant process change.

If a product has been subject to a significant process change, then it shall be tested in the same manner as a

new product.
A significant process change is defined as any of the following:
 a change in the chemical formulation (CAS No);

 reduced active ingredient concentration levels of raw materials in the polymer recipe;

 substitution of any polymer in the recipe, irrespective of any change in concentration.

Testing of a changed product may be exempted for products with a service life of more than 5 years if the

producer can demonstrate by means of regular assessment, including analyses of the process and of long-

term stabilizers, that the type of active ingredients has remained the same and that the content of these

ingredients is not lower than that in the material used in the initial durability testing.

B.1.3 Use of rework material

Rework material can be used without limitations, if the original raw material meets the requirements of this

annex and no pelletizing is done in the rework process.

If pelletizing is done in the re-work process, rework material from the same production or source can be used,

if the final product meets the requirements of this annex. If the original raw material meets the requirements of

this annex, a maximum of 10 % pelletized rework material is acceptable without further proof.

NOTE Pelletizing is a thermal process whereby the polymer melt coming from an extruder is pressed through a die

plate and cut by knives to make pellets. This process may affect the properties of the product.

B.2 Weathering (all products)

All products shall pass the accelerated weathering test described in EN 12224, unless they are to be covered

on the day of installation. The strength retained at the end of this t
