scope:

This prestandard describes a screening test method for determining the resistance of geotextiles and geotextile-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 a means of establishing a minimum acceptable level of durability. The test is applicable to any geotextile and geotextile-related products susceptible to hydrolysis, in particular polyester and polyamide based materials, and in addition to the yarns from which these geotextiles are made. This method is not intended for determining the resistance of geotextiles to hydrolysis under highly acid or alkaline conditions.
