Abstract

This document specifies a test method 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 could can be measured according to Annex D.
