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.
NOTE 2: The compressibility of the product over time will substantially influence the in-plane water flow capacity. A test method for assessing compressive creep behaviour of geotextiles or geotextile-related products is described in ENV 1897.
The test report is judged in conjunction with the long-term compressive creep behaviour in order to assess the long-term flow capacity.
