(like highly plastic, dense clays) take too long to yield measurable drops. Conversely, open-graded gravels ( ) drain water too quickly for accurate manual measurement.

Record the water level or volume consumed at regular, frequent time intervals (e.g., every 5, 10, 15, or 30 minutes).

Place a driving cap over the outer ring and drive it into the ground to a depth of roughly 150 mm (6 inches). Ensure it is driven straight down without rocking, as rocking creates air gaps along the sides of the ring (causing side-wall leakage).

: Used for evaluating liquid waste disposal sites, septic-tank fields, irrigation requirements, and potential leakage in canals or reservoirs. Scope and Soil Applicability (like highly plastic, dense clays) take too long

Water used should be similar in temperature and quality to the liquid whose infiltration is being studied.

The test involves driving two open cylinders (concentric rings) into the ground and filling them with water.

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 Share public link Record the water level or

Environmental conditions play a massive role in infiltration. The ASTM D3385-18 standard requires the recording of ambient air temperature and water temperature. Because water viscosity changes with temperature (making water flow faster when warm and slower when cold), this data is crucial for adjusting and standardizing your final infiltration rate calculations. Applications and Value of the Data

I can offer more specific insights on testing duration, expected infiltration ranges, and data adjustment methods!

You may conduct tests on bare soil or leave natural vegetation in place, depending on the conditions you are analyzing. Phase 2: Installing the Rings

The test is optimized for that exhibit low-to-moderate resistance to ring penetration. It is less effective or restricted in:
