BS EN ISO 12958:2010 Geotextiles and geotextile-related products. Determination of water flow capacity in their plane

BS EN ISO 12958 is an International Standard which specifies a method for determining the constant-head water flow capacity within the plane of a geotextile or geotextile-related product.

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.

The compressibility of the product over time will substantially influence the in-plane water flow capacity. Test methods for assessing the compressive creep behaviour of geotextiles or geotextile-related products are described in ISO 25619-1.

The test report is judged in conjunction with the long-term compressive creep behaviour in order to assess the long-term flow capacity.
