ISO 9073-11描述了当将规定质量的试验液体倒入叠加在标准吸收介质上并放置在斜面上的非织造布试样时，测量沿非织造布试样流动的试验液体（模拟尿液）量的试验方法。 本试验方法旨在比较非织造布的径流。其目的不是模拟成品的使用条件。 描述了三种替代方法: 测试I——测试亲水性非织造布的基本方法； 试验三——重复试验，试验参数与试验一相同）； 试验三——测试疏水非织造布的改进方法，规定了一种不同于试验一的台面倾角。

ISO 9073-11 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: Test I -- the basic method for testing hydrophilic nonwovens; Test III -- the repeated test, with the same test parameters as in I); Test III -- the modified method for testing hydrophobic nonwovens specifying another table inclination than in I).
