Measuring how fast water enters the ground is critical for civil engineering, environmental science, and agricultural planning. The standard protocol for this measurement is .
The official standard can be purchased and downloaded digitally as a PDF directly from the ASTM International official website or authorized technical document distributors.
Once the test begins, record the volume of liquid used to maintain the constant water level in the inner ring at regular time intervals. Common intervals range from 5 to 15 minutes, depending on the speed of infiltration.

ASTM D3385-18, titled the "Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer," provides a standardized procedure for this measurement.
The test surface must be cleared of loose vegetation and debris. The natural soil structure must remain undisturbed.
The only way to ensure you have the complete, accurate, and up-to-date standard is to obtain it from official ASTM International sales channels. You can purchase the official PDF version from: Measuring how fast water enters the ground is

The test proceeds by measuring the volume of water required to maintain a constant head in the inner ring over a set period. As the test continues, the infiltration rate typically decreases until it reaches a steady state. This final, constant rate is the standard measurement for the soil.
Always ensure you are using the most current version or the specific version mandated by your local building code or environmental protection agency. Once the test begins, record the volume of
