Standard Test Method for Pore Size Characteristics of Membrane Filters Using Automated Liquid Porosimeter (Withdrawn 2008)
01-01-2008
01-01-1999
1.1 This test method describes a procedure for measuring the pore size characteristics of membrane filters in the range of approximately 0.05 to 300 [mu]m.
1.2 This test method uses the automated bubble point method described in ASTM Test Method F316.
1.3 The liquid displacement technique used in this test method depends upon the capillary rise created by surface tension and uses the Washburn equation for calculating the pore diameter.
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
