Overview

SIST EN 13252:2014/kFprA1:2014 is a European standard developed by CEN/TC 189 that specifies essential characteristics and test methods for geotextiles and geotextile-related products used in drainage systems. The standard focuses on ensuring these materials effectively perform filtration, separation, and drainage functions in civil engineering and construction projects. It excludes geosynthetic barriers defined under EN ISO 10318, emphasizing products specifically designed for drainage applications. Additionally, it outlines performance verification processes, factory production control, and clear presentation requirements for manufacturers and distributors.

Key Topics

• Intended Functions
  Geotextiles under this standard are used for one or more of the following functions:

  • Filtration: Allowing water to pass while retaining soil particles.
  • Separation: Preventing mixing of different soil layers, always combined with filtration or drainage.
  • Drainage: Facilitating fluid flow through soil or other substrates.

• Material Durability and Service Life
  The standard provides detailed assessment criteria on the durability of geotextiles, considering factors like soil pH (4–9), temperature (up to 25 °C), and exposure conditions. It defines service life ranges-up to 5, 25, 50, and 100 years-and prescribes specific accelerated tests to simulate long-term performance for polymers such as polyester (PET), polypropylene (PP), polyethylene (PE), polyamide (PA), aramid (AR), and polyvinyl alcohol (PVA).

• Testing Procedures
  Key test methods include:

  • Accelerated weathering tests to determine maximum exposure duration on-site.
  • Hydrolysis and oxidation resistance tests tailored to polymer types with defined durations and temperature protocols.
  • Retained tensile strength measurements following exposure to standardized conditions (EN 12226).
  • Requirements for repeat testing every 5 years or following significant manufacturing changes.

• Quality Control and Product Information
  Requirements for factory production control ensure product constancy and compliance. Manufacturers must include service life predictions and exposure instructions in product documentation, enhancing transparency and usability for stakeholders.

Applications

SIST EN 13252:2014/kFprA1:2014 compliant geotextiles and related products are crucial in numerous scenarios involving drainage systems, including:

• Road construction for subgrade drainage and separation of base layers.
• Landfill and waste management sites requiring filtration layers to prevent soil contamination.
• Agricultural fields needing soil moisture regulation and erosion prevention.
• Civil engineering projects such as retaining walls and tunnels where controlled drainage is critical.
• Sports fields and landscaping requiring effective water management solutions.

These applications benefit directly from standardized product performance, ensuring longevity, environmental compatibility, and functional reliability under defined conditions.

Related Standards

Relevant standards that complement SIST EN 13252:2014/kFprA1:2014 include:

• EN ISO 10318: Defines geosynthetic barrier products, which are excluded from this drainage-specific standard.
• EN 12226: Specifies test methods for tensile strength assessment of geosynthetics following durability testing.
• EN ISO 13438: Details oxidation resistance testing procedures for geosynthetic materials.
• EN 12447: Specifies hydrolysis resistance testing for polymer-based geotextiles.
• EN ISO 3696: Defines water quality for laboratory testing, referenced for durability tests in this standard.

Adhering to these interconnected standards ensures comprehensive evaluation and quality assurance of geotextile products suited for drainage system applications.

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.

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
