1.1 This test method covers the determination of the pore size distribution of geotextile filters with pore sizes ranging from 1 to 500 m.
Note 1—The accuracy of this procedure has been verified up to a maximum pore size of 200 m. Above this value accuracy has been found to be equipment dependent and should be verified by the user through checks on materials with known opening sizes.
1.2 The test method measures the entire pore size distribution in terms of a surface analysis of specified pore sizes in a geotextile, defined in terms of the limiting diameters.
1.3 The analyst should be aware that adequate collaborative data for bias statements as required by Practice D 2777 is not provided. See the precision and bias section for details.
