Standard: NS-EN ISO 11058 Geotextiles and geotextile-related products - Determination of water permeability characteristics normal to the plane, without load (ISO 11058:1999) Author Agency: NSF
This European Standard specifies two test methods for determining the water permeability characteristics of a single layer of geotextile or geotextile-related product normal to the plane: the constant head method and the falling head method.

Standard: NS-EN ISO 12958 Geotextiles and geotextile-related products - Determination of water flow capacity in their plane (ISO 12958:1999) Author Agency: NSF
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.
This standard specifies a test method for the determination of the resistance of geotextiles to abrasion using a sliding block. After abrasion the loss in tensile properties is determined. The method is applicable to woven and nonwoven geotextiles and geotextile-related products.

Standard: NS-EN ISO 13431 Geotextiles and geotextile-related products - Determination of tensile creep and creep rupture behaviour (ISO 13431:1998) Author Agency: NSF
This Standard specifies a method for determining the tensile creep and creep rupture behaviour of geotextiles and geotextile-related products in an unconfined situation.Application of this standard is limited to those products and applications where the risk of collapse of a structure due to premature failure or to strain/time variation of the reinforcement under constant load is of essential importance.As the test is carried out over a long period of time and the procedure is complex, it is therefore recommended that the test is not considered to be a routine quality control test. The results of the test may not be representative of the performance of the products when subject to soil pressures.

Standard: NS-EN ISO 13437 Geotextiles and geotextile-related products - Method for installing and extracting samples in soil, and testing specimens in laboratory (ISO 13437:1998) Author Agency: NSF
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.

Standard: NS-EN12225 Geotextiles and geotextile-related products - Method for determining the microbiological resistance by a soil burial test Author Agency: NSF
This standard specifies a method for the determination of the microbiological resistance of geotextiles and geotextile-related products by a soil burial test. It does not specify for which products or in which applications the soil burial test is required.NOTE 1: For further reference see CR ISO 13434.NOTE 2: Experience and exhumation of geotextiles and geotextile-related products which had performed successfully, in some cases for more than two decades, indicate that geotextiles and geotextile-related products made out of synthetic materials are generally resistant against microbially initiated decay. It can thereforebe expected that most of these products commercially available at the present time will pass the soil burial test successfully and it is probably not necessary to submit them all to this test independent of their function. However, if the requirements for appropriate functioning of the geotextiles and geotextile-related products demand proof of microbiological resistance or if they are manufactured from newly developed polymers whose resistance is in any doubt, the soil burial test should be performed.
