Even with the PDF in hand, practitioners often make errors:

The permeability is calculated based on the measured flow rate, the area of the specimen, and the applied head of water.

Engineers and architects can use permeability data to design and specify porous concrete mixes that meet the performance requirements of a project. astm d3385-18 pdf

Fill both rings with water to a shallow depth (e.g., 5 cm). Let this pre-pond for a few minutes to saturate the immediate surface.

ASTM D3385-18 explicitly states that it measures infiltration rate , which is distinct from hydraulic conductivity (permeability). While related, they cannot be directly exchanged without knowing specific hydraulic boundary conditions. Procedural Requirements
