This Standard sets out the method for determining the pore-size distribution and apparent opening size (AOS) of a geotextile using the dry sieving method, and, in consequence, the equivalent opening size (EOS).
This method is applicable to geotextiles having an EOS not less than 53 um.
- Thicker fabrics or those with finer openings may need to be tested by other pore-size distribution tests.
- For fabrics with larger pore sizes, optical methods may be preferable (e.g. over 2 mm, or over 0.6 mm if suitable sand is hard to obtain).
