Geotextiles and geotextile-related products - Screening test method for determining the resistance to hydrolysis in water; German version EN 12447:2021
This document describes a screening test method to establish a minimum acceptance level of resistance of geotextiles and geotextile-related products to soil moisture. In certain polymers moisture leads to hydrolysis throughout the thickness of the fibre (internal hydrolysis) but
