UNE-EN 12447:2022

This document specifies a screening test method for determining the resistance of geotextiles andgeotextile-related products to hydrolysis by exposing test specimens to water at elevated temperatures,followed by an evaluation of the changes in properties resulting from such exposure. It is intended as ameans of establishing a minimum acceptable level of durability.The test is applicable to any geotextile and geotextile-related product susceptible to hydrolysis, inparticular polyester and polyamide based materials, and in addition to the yarns from which thesegeotextiles are made.This method is not intended for determining the resistance of geotextiles to hydrolysis under highlyacid or alkaline conditions.NOTE Performance tests to predict long-term lifetime or to compare products of different polymers or ofsimilar polymers with differing structures can be based on the same method but with a wider range oftemperatures and durations.
