Geotextiles and geotextile-related products -- Determination of water flow capacity in their plane
This European standard specifies a method for determining the constant-head water flow capacity within the plane of a geotextile or geotextile-related product.
The test report is judged in conjunction with the long-term compressive creep behaviour in order to assess the long-term flow capacity.
