scope:

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: a) Test I - the basic method for testing hydrophilic nonwovens; b) Test II - the repeated test, with the same test parameters as in a); c) Test III - the modified method for testing hydrophobic nonwovens specifying another table inclination than in a).
