Geotextiles and geotextile-related products — Determination of water flow capacity in their plane — Part 2: Performance test ISO 12958-2:2020

Publication date:   Oct 21, 2020

Scope

This document specifies a method for determining the constant-head water flow capacity within the plane of a geotextile or geotextile-related product, using boundary materials and test conditions of interest. A standard series of test conditions are proposed, involving soil confinement, low hydraulic gradients, seating times and an array of normal loads.
