This European Standard specifies the relevant characteristics of geotextiles and geotextile-related
products used in the construction of tunnels and underground structures, and the appropriate test
methods to determine these characteristics.
The intended use of these geotextiles or geotextile-related products is to protect geomembranes used
in tunnels and underground structures.
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 Tunnelbau und in Tiefbauwerken eingesetzt werden, sowie die geeigneten Prüfverfahren zur Bestimmung dieser Eigenschaften fest. Bei ihrer vorgesehenen Anwendung sollen diese Geotextilien oder geotextilverwandten Produkte als Schutz für Geomembranen, die in diesen Bauten verwendet werden, dienen. Diese Norm ist nicht auf Geomembranen anwendbar. Diese Norm behandelt die Konformitätsbewertung des Produktes bezüglich der vorliegenden Europäischen Norm und die werkseigene Produktionskontrolle.
