发布日期：2010-04
标准范围
This International Standard specifies a method for determining the constant-head water flow capacity withinthe plane of a geotextile or geotextile-related product.NOTE 1 If the full water flow capacity characteristics of the geotextile or geotextile-related product have previouslybeen established, then for control purposes it can be sufficient to determine the water flow capacity at two loads and bothgradients.NOTE 2 The compressibility of the product over time will substantially influence the in-plane water flow capacity. Testmethods for assessing the compressive creep behaviour of geotextiles or geotextile-related products are described inISO 25619-1.The test report is judged in conjunction with the long-term compressive creep behaviour in order to assess thelong-term flow capacity.
