Introduction

This European Standard allows manufacturers to describe geosynthetics 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 geosynthetics.

This European Standard is part of a series of standards, addressing the requirements for geosynthetics

when used in a specific application.

control on slopes and banks and the appropriate test methods to determine these characteristics. This

standard does not include external erosion control covered by EN 13253.

The intended use of these geosynthetics is to fulfil the function: surface erosion control.

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.

NOTE Particular application cases may contain requirements regarding additional properties and –

preferably standardized – test methods, if they are technically relevant.

4 Required characteristics and corresponding methods of test
4.1 General

The main function of geosynthetics used in surface erosion control on slopes and banks is surface

erosion control. If reinforcement 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 “–”.
