scope:

This European Standard specifies the relevant characteristics of geotextiles and geotextile-related products used in the construction of reservoirs and dams, 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, reinforcement and protection. 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.
