1.1 These test methods cover procedures for determining
the hydraulic conductivity (water permeability) of geotextiles
in terms of permittivity under standard testing conditions, in
the uncompressed state. Included are two procedures: the
constant head method and the falling head method.
1.2 The values stated in SI units are to be regarded as the
standard. The inch-pound units stated in parentheses are
provided for information only.
