This standard ( Part 17 ) covers the methods for laboratory determina-tion of coefficient of permeability of soils using falling head and the constant head methods. This test is recommended for soils with coefficient of permeability in the range 10-3 to 10-7 cm/s and maximum particle size of 9.5 mm.
