Astm D338518 Pdf -

ASTM D3385-18 establishes a standard field method using a double-ring infiltrometer to determine the water infiltration rate of soils. It is designed for assessing water movement in unsaturated, fine-grained soils for environmental and engineering projects, excluding highly pervious, impervious, or frozen materials. The full technical specification is available through ASTM International or authorized distributors. The University of Utah

Standard Dimensions: A typical setup uses a 12-inch (30 cm) inner ring and a 24-inch (60 cm) outer ring. Scope and Applicability astm d338518 pdf

The ASTM D3385-18 test method is widely used in various fields, including: ASTM D3385-18 establishes a standard field method using

ASTM D3385-18 establishes a standard field method for measuring soil infiltration rates using double-ring infiltrometers to assess hydraulic conductivity. This procedure involves maintaining a constant water head in concentric rings, measuring vertical water flow to determine the infiltration rate [1]. You can access the full standard through the ASTM website. The University of Utah Standard Dimensions : A

Standard Test Method for Infiltration Rate of Soils in Field Using Double-Ring Infiltrometer

I’m unable to provide or share the actual PDF file for ASTM D3385-18 (note the correct numbering—often "D3385," not "D338518") because it is a copyrighted document owned by ASTM International. However, I can tell you a proper story about this standard: what it is, why it exists, and how it's used.
