DANSK DSF/FPREN ISO 13437 PDF

This standard specifies a method for the on-site installation, retrieval and testing of geotextile samples, irrespective of the particular degradation mechanisms to which they are exposed. The method is also appropriate to test for mechanical damage, much of which occurs during installation, and to provide an owner with information about the state of the geotextile or geotextile-related product in his structure. NOTE – : The durability of geotextiles or geotextile-related products is assessed by short-term accelerated tests under conditions more extreme than those experienced in service. In order to establish the validity of these tests it is essential to compare their predictions with tests made on material extracted from site.
