Geotextiles and geotextile-related products -- Determination of water permeability characteristics normal to the plane, without load
This standard has been revised by ISO 11058:2019
ISO 11058:2010 specifies two test methods for determining the water permeability characteristics of a single layer of geotextile or geotextile-related product normal to the plane:
- the constant head method;
- the falling head method.
