Astm D3385-18 Pdf

Searching for is the first step in ensuring your field infiltration tests are defensible, repeatable, and compliant. The 2018 edition provides critical updates that previous versions lack – especially in data recording frequency and water quality control.

Determining irrigation requirements and leaching efficiencies.

: Typically 12 inches (30 cm) in diameter. This is where the actual measurement takes place. Outer Ring

Drive both rings concentrically into the soil to a depth of 5–10 cm (or deeper if shallow, permeable soil). Ensure no smearing of the sidewalls. astm d3385-18 pdf

The test is conducted by applying water to the specimen through the testing apparatus and measuring the volume of water that passes through over a specified period.

: The test usually runs until the infiltration rate becomes steady (equilibrated), which can take several hours depending on soil type. Standard Procedure Steps Site Preparation

In geotechnical engineering, environmental science, and agricultural hydrology, understanding how quickly water moves into the soil is critical. Whether you are designing a septic leach field, a stormwater retention basin, or an irrigation system, the of the soil dictates success or failure. Searching for is the first step in ensuring

The full title of the standard is "Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer". It provides a standardized procedure for quantifying the speed at which liquids—typically water—enter the soil surface under a constant head. This standard is primarily used for:

Acts as a buffer, creating a "curtain" of water that minimizes the lateral (sideways) spread of water from the inner ring.

The test method outlined in ASTM D3385-18 involves measuring the rate at which water flows through a porous concrete sample under a specified head (pressure) of water. The procedure includes: : Typically 12 inches (30 cm) in diameter

: Typically 24 inches (60 cm) in diameter. It acts as a buffer to saturate the surrounding soil and force the inner ring's water to flow vertically. Constant Head

A: The standard suggests a minimum of three tests per soil unit, spaced adequately to avoid interference (typically > 3 m apart).
