: Detailed descriptions of the equipment needed for the test are provided, including sieves, a mechanical sieve shaker, and balances.

Today, D3385-18 is still the go-to field method. It’s not glamorous. It involves buckets, stopwatches, and a lot of waiting. But it tells a simple truth about the ground beneath our feet: how fast it drinks water. And that truth underpins safe foundations, clean water, and sustainable land use. astm d338518 pdf

is the recognized international standard for determining the infiltration rate of soils in the field using a double-ring infiltrometer . This method is essential for geotechnical and environmental engineering, providing data for septic tank design, irrigation planning, and groundwater recharge studies. Core Objectives of ASTM D3385-18 : Detailed descriptions of the equipment needed for

For tighter soils, intervals can be extended to every 30 to 60 minutes. It involves buckets, stopwatches, and a lot of waiting

A double-ring infiltrometer is a relatively simple—though slow—method of measuring the hydraulic conductivity or design infiltration rate of a given soil. The typical setup consists of an open outer ring and a sealed or covered inner ring, with both rings driven concentrically into the soil to a specified depth.

Fill both the inner and outer rings with water simultaneously to a depth of approximately 1 to 4 inches (2.5 to 10 cm).
