BS EN ISO 11058:2010 Geotextiles and geotextile-related products. Determination of water permeability characteristics normal to the plane, without load

BS EN ISO 11058 specifies two test methods for determining the water permeability characteristics of a single layer of geotextile or geotextile-related product normal to the plane:

a) The constant head method;
b) The falling head method.

If the full permeability characteristics of the geotextile or geotextile-related product have previously been established, then for control purposes it can be sufficient to determine the velocity index at a head loss of 50 mm only.
