This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products
used in the construction of railways, 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 applies in
superstructure-ballast or substructure-blanket layer, within a subgrade.
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.
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.
Diese Norm legt die wichtigsten Eigenschaften von Geotextilien und geotextilverwandten Produkten, die im Eisenbahnbau verwendet werden, sowie die geeigneten Prüfverfahren zur Bestimmung dieser Eigenschaften fest. Bei ihrer vorgesehenen Anwendung sollen diese Geotextilien oder geotextilverwandten Produkte eine oder mehrere der folgenden Funktionen erfüllen: Trennen, Bewehren und Filtern. Diese Norm gilt für Oberbau-Bettungsschichten oder Unterbau-Deckschichten innerhalb eines Gleisbetts. Die Norm ist nicht auf Beton- und Asphaltschichten sowie auf Geomembranen anwendbar. Diese Norm behandelt die Konformitätsbewertung des Produktes bezüglich der vorliegenden Europäischen Norm und die werkseigene Produktionskontrolle.
