When water is poured into a single ring driven into the ground, it tends to lateralize—diverging sideways as it moves downward due to capillary action and gravity. This lateral flow artificially inflates the measured infiltration rate. The double-ring infiltrometer solves this issue:

Typically 12 inches (approx. 30 cm) in diameter.

Hi everyone — I'm looking for the ASTM D3385-18 standard (Standard Test Method for Shear Strength of Adhesives by Punch Tool and Die) in PDF format or any guidance on its key procedures and specimen dimensions. Specifically I need:

The official scope of the standard specifies the following key elements: astm d338518 pdf

Tests made at the same site are not likely to give identical results, and the rate measured by this test method is primarily for comparative use.

While highly effective, ASTM D3385-18 is not universally applicable. Engineers must be aware of its limitations:

You can buy the ASTM D3385-18 standard directly from ASTM International through their official website ( www.astm.org ). When water is poured into a single ring

The 2018 revision (D3385-18) clarified procedures for different soil types, added guidance on test duration, and emphasized the importance of maintaining constant head (water depth) during the test. It also addressed common errors: ring-driving disturbance, evaporation, and temperature effects.
