GEOTEXTILES AND GEOTEXTILE-RELATED PRODUCTS – DETERMINATION OF WATER PERMEABILITY CHARACTERISTICS NORMAL TO THE PLANE, WITHOUT LOAD (ISO 11058:1999, IDT)
This Malaysian Standard specifies two test methods for determining the waterpermeability characteristics of a single layer of geotextile or geotextile-related product normal to the plane: the constant head method and the falling head method.
NOTE: If the full permeability characteristics of the geotextile or geotextile-related product have previously been established, then for control purposes itcan be sufficient to determine the velocity index at a head loss of 50 mm only.
