Standard Test Method for Pore Size Characteristics of Geotextiles by Capillary Flow Test

Importancia y uso:

5.1 This test method may be used to:

5.1.1 Determine the pore size distribution of a geotextile,

5.1.2 Determine the maximum pore size of a geotextile,

5.1.3 Determine the mean flow pore size of a geotextile,

5.1.4 Determine the effect of processes such as calendaring or needle punching upon the pore size distribution,

5.1.5 Determine the effect of compression upon the pore size distribution of a geotextile, if the test equipment allows, and

5.1.6 Determine the gas flow rate of a geotextile, and thereby its gas flow capability.

5.2 The pore size distribution test may also be used for research, material development, or to assess clogging on field-retrieved samples.
