DIN EN 13253-2005 土工织物及其相关产品.用于外磨损控制系统的土工织物及其相关产品要求的特性
Geotextiles and geotextile-related products - Required characteristics for use in external erosion control systems(includes Amendment A1:2005); English version of DIN EN 13253:2000 + A1:2005
This European Standard specifies the relevant characteristics of geotextiles and geotextile-related
products used in erosion control works for preventing the migration of fine-graded material into layers
of coarser material due to alternating hydraulic gradients. This standard also specifies the appropriate
test methods to determine these characteristics.
This standard covers applications in coastal protection and bank revetment. This standard does not
cover surface erosion, where the geotextile or geotextile-related product is located at the surface.
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 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.
