To ensure your engineering calculations, geotechnical reports, or environmental assessments are legally compliant and technically accurate, you should utilize the official publication. You can purchase, view, or download the full directly from the official ASTM Store.

Simultaneously fill both the inner and outer rings with water to a predetermined depth (typically between 25 mm and 100 mm). It is vital to maintain an identical water level in both rings throughout the test duration to eliminate any head-induced hydraulic gradients between the two rings. Step 5: Data Recording

If you want, I can: provide a one‑page printable cheat sheet for performing a D3385 test in the field, or produce the sample calculation and an example infiltration‑vs‑time plot from realistic measurement data. Which would you prefer? astm d338518 pdf

A Comprehensive Guide to ASTM D3385-18: Field Measurement of Soil Infiltration Rate

ASTM D3385-18, officially titled “Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometers,” serves as the industry benchmark for this measurement. By utilizing a concentric ring apparatus, the method aims to minimize lateral flow divergence, thereby providing a more accurate representation of the vertical hydraulic conductivity of the soil. This paper dissects the standard, offering guidance on its practical application and theoretical basis. It is vital to maintain an identical water

ASTM D3385-18 specifies stringent requirements for the equipment used to ensure data reliability.

The is the core apparatus. It consists of two concentric metal rings driven into the soil. Water is maintained at a constant level in both rings. The inner ring measures the vertical infiltration rate, while the outer ring creates a buffer zone to minimize lateral spread of water, ensuring that flow in the inner ring is predominantly one-dimensional (vertical). A Comprehensive Guide to ASTM D3385-18: Field Measurement

ASTM D3385-18 is a standardized field test method published by ASTM International (formerly known as the American Society for Testing and Materials). The full title is:

is the definitive international standard for field-measuring the infiltration rate of liquids into soils using a double-ring infiltrometer . Managed under the jurisdiction of ASTM Committee D18 on Soil and Rock , this active standard spans 8 pages and details the required engineering equipment, test setups, and formulaic calculations necessary to evaluate site drainage capacity. Civil engineers, hydrogeologists, and environmental scientists use the official ASTM D3385-18 Document to inform storm-water management design, agricultural irrigation layouts, and landfill liner efficiency. 1.
