The characteristic opening size is obtained by determining the particle size distribution of a graded granular material that is washed through a single layer of geotextile using the geotextile as a sieve. The test specifios a pro-treatment, minimum sieve size, mass of granular matenal, sieve amplitude and test duration.The geotextile acts as a sieve and the granular material, which passes the geotextile, is analyzed. The characteristic opening size (090) of the geotextile corresponds to a specified size of the granular material passed (d90). Test Standard : BS EN ISO-12956:2010
