This European standard specifies a method for determining the constant-head water flow capacity within the plane of a geotextile or geotextile-related product. Note: If the full water flow capacity characteristics of the geotextile or geotextile-related product have previously been established, then for control purposes it can be sufficient to determine the water flow capacity at two loads and both gradients.
