This part of ISO 9073 describes test methods for measuring the quantity of test liquid (simulated urine) which runs down a nonwoven test piece when a specified mass of test liquid is poured on to the nonwoven test piece superimposed on a standard absorbent media and placed on an inclined plane.
This test method is designed to compare run-off of nonwovens. It is not intended to simulate in-use conditions of finished products.
Three alternative methods are described:
  1. a) Test I — the basic method for testing hydrophilic nonwovens;
  2. b) Test II — the repeated test, with the same test parameters as in a);
  3. c) Test III — the modified method for testing hydrophobic nonwovens specifying another table inclination than in a).
