ENV 12447 : 1997

Gives a screening test method to determine the resistance of geotextiles and geotextile-related products to hydrolysis by exposing test specimens to water at elevated temperatures, then by an evaluation of the changes in properties that result from such an exposure. It is meant as a means of establishing a minimum acceptable level of durability. Applies to any geotextile and geotextile-related product susceptible to hydrolysis, particularly polyester and polyamide based materials, and additionally to the yarns from which these geotextiles are made. This method is not meant to determine the resistance of geotextiles to hydrolysis under high acid or alkaline conditions.
