IS 2720 : Part 17 : 1986 Methods of Test for Soils - Part 17 : Laboratory Determination of Permeability

1 Scope

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