The project applies to the test of the filterspecific bubble point when using suitable moistening fluids. Depending from the filter material and from the moistening fluids, it serves as filterspecific coefficient for the characterization and quality control of membrane filters with a nominal pore size of 0,1 ? preferably of flat filters having an effective filter area up to 700 cm<(hoch)2>.
