... method, which provides a volumetric pore size. This test identifies the constriction size of each pore channel in a geotextile, where retention and clogging are most critical. The bubble point test method is advantageous because it provides for the complete pore size distribution of the geotextile, can...

... The capillary flow porometry(CFP)technique, known as the bubble point method, has been applied to measure the entire pore size distribution (PSD)of nonwoven geotextiles. The classical technique is based on the differential analysis of two test runs: a wet run, during which the specimen...

... geotextiles more than the pressure table option. For image analysis a one dimensional model was used to measure the pore size distribution from enlarged photographic prints of thin sections. The results from the two methods indicated similar pore size distribution for geotextiles from the same manufacturer...

... Quantification of the porous nature of a flat filter medium can be accomplished in a variety of ways. However, some of the commonly used methods are either inadequate or irrelevant. For example, incremental porosimetry does not produce pore size distributions that can be related to filter...
