Theresistance of geotextile products to these chemicals depends on the one hand on polymerformulation, processing, textile structure and the presence of existing damage and on theother hand on the composition of the liquid and in situ conditions such as temperature,pressure and the presence of further mechanical stress.It is the purpose of this standard to provide a method of screening (index testing) theresistance of geotextile products to these acids and bases.Since an index test requires exposure times that are short compared to the expectedlifetimes of geotextile products, it is necessary to accelerate the process.
The dataobtainable are suitable for screening but not for deriving performance data such as lifetime,unless supported by further evidence.NOTE
This standard should be used with reference to CR ISO 13434.1ScopeThis standard specifies methods for screening the resistance of geotextile products toliquids while not subjecting them to external mechanical stress.The standard is applicable to all geotextiles and geotextile related products.Method A applies particularly to polyamides and method B to polyesters and polyamides.The test results should be interpreted in the context of site conditions.NOTE
This standard only considers conditions where the specimens are fully immersed in theliquids.
Though outside the scope of this standard, the test conditions may be modified toaccommodate particular applications, e.g. gaseous media.
This standard does not preclude use fortest specimens that are pre-treated by some method, e.g. by weathering, aqueous extractionconditions or installation damage.2Normative referencesThis European Standard incorporates by dated or undated reference, provisions from otherpublications.
