标准摘要
[中文适用范围]： ISO 9073-11 描述了测量测试液体（模拟尿液）在施加一定质量液体至置于标准吸收介质上并置于斜面的非织造测试样品上后，沿该非织造样品流下的液体量的试验方法。该方法旨在比较不同非织造材料的液体流失情况，但并不旨在模拟成品在实际使用中的条件。标准中提供了三种替代试验方法：试验 I——用于测试亲水性非织造材料的基本方法；试验 II——重复试验，采用与试验 I 相同的测试参数；试验 III——针对疏水性非织造材料改良的方法，采用与试验 I 不同的斜面倾角。 [外文原描述]： This document specifies test methods to measure the amount of test liquid (simulated urine) which runs down a nonwoven test specimen when a specified mass of test liquid is poured on the nonwoven test specimen superimposed on a standard absorbent medium and placed on an inclined plane. This document is designed to compare run-off of nonwovens. It is not intended to simulate in use conditions for finished products. The three methods are: a) Option A - basic method for testing hydrophilic nonwovens, see Annex A. b) Option B - repeated test, with the same test parameters as the basic method with additional information in Option A, see Annex B. c) Option C - modified method for testing hydrophobic nonwovens specifying another degree of incline, see Annex C. The test method is designed to measure the repellency of hydrophobic nonwovens. At the standard inclination angle, Option A isn’t able to distinguish between different levels of hydrophobicity. By decreasing the inclination of the table, one can assess the difference in repellence of hydrophobic nonwovens. For R&D purposes, other characteristics can be measured according to Annex D.
