Resumen:
This standard specifies methods for screening the resistance of geotextile products to liquids 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 the liquids. Though outside the scope of this standard, the test conditions may be modified to accommodate particular applications, e. g. gaseous media. This standard does not preclude use for test specimens that are pre-treated by some method, e. g. by weathering, aqueous extraction conditions or installation damage.
