DIN EN 13253/A1:2014-08

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, and 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 will always occur in conjunction with filtration or reinforcement, and hence shall not be specified alone.This standard is not applicable to geosynthetic barriers, as defined in EN ISO 10318.This standard provides for the assessment and verification of constancy of performance of the product to this European Standard and for factory production control procedures.
