ASTM D3385-18 references several other ASTM standards that may be used in conjunction with it for comprehensive soil testing and site characterization:

: The testing procedure involves dry sieving of geotextile samples with soils of known gradation. The percentage of soil passing through the geotextile is related to the pore size distribution.

Civil engineers use the data to size septic tank leach fields and soil absorption systems safely.
