Usually 24 inches (600 mm) in diameter. It acts as a buffer to limit the lateral spread of water, ensuring that water from the inner ring moves in a one-dimensional, vertical flow for more accurate results. Test Procedure and Methodology

While ASTM D3385-18 provides a valuable tool for evaluating geotextiles, there are challenges and limitations, including variability in testing results and the influence of test conditions on the measured pore size distribution. Additionally, field performance can sometimes differ from laboratory results due to installation conditions, soil properties, and long-term degradation.

Overall, the ASTM D3385-18 PDF report provides a valuable resource for professionals and researchers working in the fields of hydrology, soil science, and environmental engineering.

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